Description

Technical Field

[0001] The utility model relates to the field of touch screens, in particular to a deformation detection device for touch screen production. Background Technique

[0002] A touch screen is a common human-computer interaction device that can emit signals to a processor by detecting touches to achieve human-computer interaction. After the touch screen is produced, it usually needs to be detected, including deformation detection. Deformation detection can detect whether the outer wall of the device is flat. When performing deformation detection, a fixing frame is usually used to fix the to-be-detected flat plate on the workbench surface. Most of the existing fixing frames are integrally formed and cannot be adjusted, so they cannot adapt to devices of multiple models.

[0003] After retrieval, Chinese Patent Publication No.: CN220649348U discloses a deformation detection device for touch screen production, which relates to the technical field of touch screen detection. To solve the problem that after the existing touch screen is produced, the surface of the touch screen generally needs to be subjected to deformation detection to determine the yield rate of the touch screen, and the existing touch screen deformation detection device cannot accurately detect the surface of the touch screen, resulting in a high detection error rate and poor detection effect. The device includes a processing table; and also includes: brackets, which are arranged on both sides of the upper end of the top plate. The upper ends of the brackets are fixedly installed with a top plate. A detection seat is arranged in the middle below the top plate. A telescopic tube is arranged at the bottom of the detection seat, and a plurality of telescopic tubes are arranged and symmetrically arranged in two rows on both sides of the bottom of the detection seat. A circular groove is integrally formed on the upper side inside the telescopic tube. A telescopic groove is arranged at the bottom of the circular groove, and the telescopic groove penetrates through the bottom of the telescopic tube.

[0004] When the device is in use, a placement groove is used to accommodate the device. Although fixation can be achieved, since the internal shape of the placement groove cannot be adjusted, it cannot adapt to touch screens of multiple different sizes, and the overall applicability of the device is poor. Therefore, a deformation detection device for touch screen production is proposed to solve the above problems. Summary of the Utility Model

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0033] Referring to Figure 1 - Figure 3 , an embodiment provided by the present invention: a deformation detection device for touch screen production, including a machine table 1 for supporting the whole device. At the top end of the inner wall of the machine table 1, a detection head 2 for detecting the deformation amount of the touch screen is installed. At the bottom end of the inner wall of the machine table 1, a fixing component 4 for fixing the touch screen is provided. The fixing component 4 includes a support frame 41 for accommodating the touch screen. The support frame 41 is set in a U shape with the opening facing forward. The bottom end of the support frame 41 is fixedly connected to the bottom end of the inner wall of the machine table 1. At the front end of the support frame 41, a support component 3 for supporting the touch screen is provided. The support component 3 includes a slide plate 31 for supporting the movement of the whole support component 3. The slide plate 31 penetrates and is slidably connected to the front end of the support frame 41. The slide plate 31 can slide back and forth at the front end of the support frame 41. At the top end of the slide plate 31, a slide bar 36 for supporting a support plate 32 is slidably connected. The top end of the slide bar 36 is fixedly connected to a support plate 32 for directly supporting the touch screen.

[0034] Referring to Figure 2 - Figure 4 , the support component 3 further includes a baffle 34 for pulling the rear end of the touch screen. The bottom end of the baffle 34 is fixedly connected to the top end of the support plate 32 near the rear end. At the top end of the support plate 32 near the front end, an empty groove 33 for facilitating the operator to move the support plate 32 is provided. At the top end of the slide plate 31, a groove 35 for accommodating the back circuit of the touch screen is provided. At the top end of the slide plate 31, a receiving groove 38 for accommodating a support spring 37 is provided. At the top end of the receiving groove 38, a support spring 37 for pushing the support plate 32 upward is fixedly connected. The top end of the support spring 37 is fixedly connected to the bottom end of the support plate 32. When the top end of the support plate 32 is not squeezed, the support spring 37 will push the support plate 32 upward to make it move upward. At the front end of the support frame 41, an arc surface 48 for squeezing the support plate 32 is provided. The top end of the arc surface 48 is higher than the top end of the support plate 32. When the support plate 32 moves backward, it will be squeezed by the arc surface 48 and forced to move downward.

[0035] Referring to Figure 4 - Figure 6The inner wall of the support frame 41 is fixedly connected with a sleeve 42 for supporting the rotation of the rotating rod 43. The right end of the sleeve 42 penetrates and is rotatably connected with a rotating rod 43 for driving the fixed block 44 to move. The outer wall of the rotating rod 43 is slidably provided with a fixed block 44 for fixing the touch screen. The front end of the fixed block 44 is provided with an inclined surface. When the inclined surface is squeezed, the fixed block 44 will be forced to move outward. The rear end of the fixed block 44 is slidably connected to the inner wall of the support frame 41. The fixed block 44 can slide left and right on the inner wall of the support frame 41 and cannot be separated from the inner wall of the support frame 41. The outer wall of the rotating rod 43 is provided with an arc groove for squeezing the protrusion 47; the inner wall of the fixed block 44 is fixedly connected with a protrusion 47 for squeezing the protrusion 47. The protrusion 47 slides on the inner wall of the arc groove. When the rotating rod 43 rotates, the protrusion 47 will be squeezed through the arc groove to drive the fixed block 44 to move. The inner wall of the sleeve 42 is provided with a storage groove 45 for accommodating a torsion spring 46. The storage groove 45 is fixedly connected with a torsion spring 46 for driving the rotating rod 43 to rotate. The left end of the torsion spring 46 is fixedly connected to the outer wall of the rotating rod 43. There are multiple groups of fixed blocks 44, protrusions 47, and arc grooves. The multiple groups of fixed blocks 44, protrusions 47, and arc grooves are symmetrically arranged with the center line of the sleeve 42 as the symmetry axis. The arc grooves on both sides of the rotating rod 43 rotate in opposite directions. When the rotating rod 43 rotates, the two groups of protrusions 47 will drive the two groups of fixed blocks 44 to move in opposite directions.

[0036] Working principle: when detection is required, the touch screen needs to be placed on the top of the support plate 32 first, and then the slide plate 31 can be pushed backward. The slide plate 31 will drive the support plate 32 to move backward synchronously, and the arc surface 48 will squeeze the top of the support plate 32, thereby forcing the support plate 32 to move downward until the bottom end of the support plate 32 fits the top of the slide plate 31, and at the same time, the touch screen will also contact the fixed block 44. The fixed block 44 will first squeeze the touch screen so that its front end is close to the rear end of the support plate 32. When the touch screen is close to the rear end of the support plate 32, the touch screen will squeeze the fixed block 44 under the support of the support plate 32 to move outward. At the same time, the fixed block 44 will also squeeze the touch screen toward the middle position under the action of the rotating rod 43, the torsion spring 46, the arc groove, and the protrusion 47 to align its center position with the center position of the support frame 41. This makes it convenient to locate the measuring point. When the slide plate 31 is fully inserted into the interior of the support frame 41, the touch screen is fixed.

[0037] When the detection is completed, the slide plate 31 can be pulled outward. When the top of the support plate 32 is no longer squeezed by the arc surface 48, the support spring 37 can push the support plate 32 upward to drive the touch screen to move upward, so that the operator can easily take out the touch screen.

[0038] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
