Description

Technical Field

[0001] This utility model relates to the field of product flatness screening technology, specifically a product flatness screening tool. Background Technology

[0002] Plastic sheets are widely used in electronics, packaging, building materials, automotive interiors and other fields due to their lightweight, corrosion resistance and easy processing properties. Their flatness accuracy directly affects the assembly effect, functionality and service life of the product. Excessive flatness of plastic sheets can cause a series of problems. For example, plastic sheets used for monitor backlights and printer housings may not fit tightly with other parts during assembly if they are not flat.

[0003] Currently, the flatness inspection of plastic sheets mainly relies on manual inspection using rulers and feeler gauges. Operators need to compare gaps along different directions on the surface of the plastic sheet, and the inspection of a single piece takes about 1-3 minutes. The inspection error increases and the accuracy is difficult to guarantee. Alternatively, laser scanning inspection equipment can be used, which can achieve non-contact high-precision inspection, but the equipment cost is high. The plastic sheet needs to be fixed and positioned during inspection, and the inspection of a single piece takes more than 2 minutes. Utility Model Content

[0004] The purpose of this application is to provide a product flatness screening tool to solve the technical problems of long detection time and high cost of plastic sheet flatness in the prior art.

[0005] To achieve the above objectives, the technical solution adopted in this application is: to provide a product flatness screening tool, comprising: a support frame, a frame fixedly installed on the top of the support frame, the middle of the frame being inclined downwards, the two ends of the frame being parallel, and two partition plates fixedly connected to the bottom of the frame;

[0006] A flatness screening mechanism is provided between the two partition plates to quickly determine whether the flatness of the product is qualified. The flatness screening mechanism includes a sliding plate, a buffer plate, a screw, and a screening plate.

[0007] Furthermore, a sliding plate is fixedly installed between the two inclined surfaces in the middle of the partition plates on opposite sides. A buffer plate is fixedly connected to one side of the bottom of the sliding plate. A screw is provided on the sliding plate, and a screening plate is rotatably connected to the bottom end of the screw.

[0008] Furthermore, the screening plate and the sliding plate are parallel to each other, and their opposing surfaces are both smooth surfaces.

[0009] Furthermore, a connecting rod a is fixedly connected between the two middle inclined surfaces of the partition plates on opposite sides. A threaded sleeve is provided at the middle position of the connecting rod a, and a handwheel is fixedly installed at the top of the threaded rod.

[0010] Furthermore, connecting rods b are provided on both sides of connecting rod a, and the two ends of connecting rod b are respectively connected to the inner walls of the two partition plates. Each connecting rod b is provided with two symmetrically distributed guide cylinders.

[0011] Furthermore, each of the guide cylinders is slidably connected with a guide rod, and the bottom end of each guide rod is connected to the top of the screening plate.

[0012] The beneficial effects of this utility model are:

[0013] The advantages of this invention are that by placing the plastic plate on the sliding plate, the sliding plate slides down along its inclined surface, allowing the plastic plate to slide between the screening plate and the sliding plate. The chamfered edges on both sides of the screening plate facilitate the smooth sliding of the plastic plate. Qualified products automatically slide down the inclined surface of the sliding plate to the buffer plate without manual intervention. Unqualified products can be manually removed. The entire process does not require complex positioning or waiting, significantly shortening the inspection time for a single item, and is also low in cost. Attached Figure Description

[0026] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0027] Example 1

[0028] As attached Figures 1 to 5 The product flatness screening fixture shown includes: a support frame 1, a frame 11 fixedly installed on the top of the support frame 1, the middle of the frame 11 is inclined downwards, the two ends of the frame 11 are parallel, two partition plates 12 are fixedly connected to the bottom of the frame 11, and a flatness screening mechanism is located between the two partition plates 12 for quickly determining whether the flatness of the product is qualified.

[0029] Specifically, when checking the flatness of the plastic sheet, the plastic sheet is moved to the inclined surface of frame 11 and slides down the inclined surface. The plastic sheet is then screened by the flatness screening mechanism, thereby removing plastic sheets that do not meet the flatness requirements. Plastic sheets that meet the flatness requirements will pass under the flatness screening mechanism, while plastic sheets that do not meet the flatness requirements cannot pass under the flatness screening mechanism and can be manually removed, thus improving the efficiency of the flatness detection of the plastic sheet.

[0030] Based on Embodiment 1, the solution in Embodiment 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 5 As shown below, see details:

[0031] The flatness screening mechanism includes: a sliding plate 2, a buffer plate 21, a screw 24, and a screening plate 25. The sliding plate 2 is fixedly installed between the opposite sides of the inclined surfaces in the middle of the two partition plates 12. The buffer plate 21 is fixedly connected to one side of the bottom of the sliding plate 2. The screw 24 is provided on the sliding plate 2. The bottom end of the screw 24 is rotatably connected to the screening plate 25. The screening plate 25 is parallel to the sliding plate 2, and their opposite surfaces are smooth. A connecting rod a22 is fixedly connected between the opposite sides of the inclined surfaces in the middle of the two partition plates 12. A screw sleeve 23 is provided at the middle position of the connecting rod a22. A handwheel 26 is fixedly installed at the top of the screw 24. Connecting rods b27 are provided on both sides of the connecting rod a22. The two ends of the connecting rod b27 are respectively connected to the inner walls of the two partition plates 12. Two symmetrically distributed guide cylinders 28 are provided on each connecting rod b27. Guide rods 29 are slidably connected inside each guide cylinder 28. The bottom ends of the guide rods 29 are respectively connected to the top of the screening plate 25.

[0032] Specifically: When inspecting the flatness of the plastic sheet, the distance between the screening plate 25 and the sliding plate 2 is adjusted according to the flatness parameters of the plastic sheet. The screw 24 is rotated by manually turning the handwheel 26. The external thread of the screw 24 engages with the internal thread on the inner wall of the screw sleeve 23. The screw sleeve 23 is fixed by the connecting rod a22, thus driving the screw 24 to move axially. When the screw 24 moves, it drives the screening plate 25 to move. The screening plate 25 is restricted by four guide rods 29 and four guide cylinders 28 to prevent rotation and guide its movement. The bottom end of the screw 24 is rotatably connected to the screening plate 25. The rotation direction of the handwheel 26 is controlled to adjust the direction of the screening plate 25. The direction of movement of the screen plate 25 is adjusted to increase or decrease the distance between the screen plate 25 and the sliding plate 2, so that the distance between the screen plate 25 and the sliding plate 2 is exactly the distance of the plastic plate flatness qualification parameter. The left and right sides of the screen plate 25 are chamfered to facilitate the plastic plate to slide into the space between the screen plate 25 and the sliding plate 2. The plastic plate with qualified flatness can pass between the screen plate 25 and the sliding plate 2. The passed plastic plate slides down the inclined surface of the sliding plate 2 and falls onto the buffer plate 21. The buffer plate 21 slows down the sliding speed of the plastic plate. The plastic plate with unqualified flatness will get stuck between the screen plate 25 and the sliding plate 2. At this time, the unqualified plastic plate can be manually removed and moved to the sliding plate 2 for screening, which improves efficiency.

[0033] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
