[0019] The advantages and features of the present application will be more readily understood in connection with the preferred embodiments of the present application described in detail below with reference to the accompanying drawings, so as to define the scope of the present application more clearly and explicitly.

[0020] Please refer to Figure 1 and Figure 2 The embodiment of the present application comprises:

[0021] A touch panel hand feeling detection jig, the touch panel hand feeling detection jig comprises an upper cover plate 1 and a lower cover plate 2, the upper cover plate 1 and the lower cover plate 2 are hinged through a hinge 3, the upper cover plate 1 is a rectangular hollow plate frame, a plurality of detection grooves 201 with different groove depths are circumferentially arranged on the upper surface of the hollow plate frame, the position of each detection groove 201 corresponds to the position of an infrared sensor on a jig station of a test workbench, and whether the thickness of the touch panel placed on the lower cover plate 2 is qualified can be directly judged through the sensing signal of the infrared sensor. A pressing groove 202 is circumferentially arranged on the inner side of the lower surface of the hollow plate frame, a slope structure inclined to the inner side of the hollow plate frame is arranged on the upper surface of the hollow plate frame at the position corresponding to the groove bottom of the pressing groove 202, the lower cover plate 2 has the same contour as the upper cover plate 1, nine convex columns 103 are symmetrically arranged on the plate surface of the lower cover plate 1 corresponding to the area of the pressing groove 202, simulating the actual installation state of the touch panel, six of which are symmetrically arranged on both sides, one is arranged in the front, and two are symmetrically arranged about the central axis at the back, six magnetic attraction pieces 102 are uniformly arranged on the plate surface outside the contour surrounded by the nine convex columns 103, screw locking positions 107 are arranged on the four corners of the plate surface of the lower cover plate 1, and avoiding holes 101 are arranged in the middle, there are two avoiding holes 201, one is a rectangular long hole, and the other is a square hole, which can prevent the control circuit at the back of the touch panel from being damaged during testing. By arranging the pressing groove 202, the touch panel can be clamped around after being placed in the corresponding position, which can prevent the plate surface from sliding during detection. Nine polyurethane gaskets 203 are symmetrically arranged on the groove bottom of the pressing groove 202 about the central axis of the pressing groove 202, each polyurethane gasket 203 corresponds to a convex column 103, the height of the polyurethane gasket 203 beyond the groove bottom plane of the pressing groove 202 is between 0.3-0.8mm, and it is generally 0.5mm in actual production. Such arrangement can avoid the groove bottom of the pressing groove 202 directly pressing the edge of the touch panel, because the entire jig is made of stainless steel and has high hardness, the stress on the top of the convex column 103 will be very concentrated when the groove bottom of the pressing groove 202 directly presses the four corners of the touch panel, which can easily damage the touch panel to be detected, and the use of the polyurethane gasket 203 can not only press the touch panel to be detected tightly to meet the detection requirements, but also effectively reduce the probability of damage due to the relatively small hardness of the polyurethane gasket 203.

[0022] The two positioning holes 204 are symmetrically arranged on the groove bottom of the pressing edge groove 202 on both sides of the upper cover plate 2, and the positioning column 104 is arranged at the corresponding position of the lower cover plate 1. In this way, the to-be-inspected touch panel can be quickly aligned when placed, and the placing efficiency is improved.

[0023] A plurality of cover opening positions are arranged on the outer edge of the lower surface of the upper cover plate 2, and the lower cover plate edge is provided with a corresponding cover opening avoiding groove at the position corresponding to each cover opening position. The cover opening positions are divided into two types, one is the side cover opening position 206 arranged on both sides, and the other is the front cover opening 205 arranged in the middle of the front surface of the upper cover plate. The side cover opening avoiding groove 106 and the front cover opening avoiding groove 105 are respectively arranged at the corresponding positions of the lower cover plate 1. The reason for arranging the cover opening position is that the whole jig is arranged by six strong magnetic suction pieces 102 to be combined together between the upper cover plate 2 and the lower cover plate 1 in order to improve the pressing stability, and it is not easy to separate by fingers. After the special cover opening position and the corresponding cover opening avoiding groove are arranged on the periphery, the fingers of the on-site personnel can conveniently extend into the cover opening position and the cover opening avoiding groove to separate the upper cover plate from the lower cover plate.

[0024] The screw avoiding corner groove 207 is arranged at the position corresponding to the screw locking position 107 of the lower cover plate 1 on the four corners of the lower surface of the upper cover plate 2. The screw avoiding corner groove 207 can prevent the screw on the screw locking position 107 from being stuck when loosened, and affect the accuracy.

[0025] The above-mentioned is only an embodiment of the present application, and does not limit the patent range of the present application, and any equivalent structure or equivalent process transformation, or direct or indirect application in other related technical fields, is also included in the patent protection range of the present application.
