Referring to fig. 1 and fig. 2, fig. 1 shows a schematic view of a detection tool 100 and a workpiece 200 in some embodiments, and fig. 2 shows a schematic view of the workpiece 200 placed in the detection tool 100 in some embodiments. The detection jig 100 can bear the workpiece 200 and limit the workpiece 200, so that the manual handheld detection jig 100 can detect the appearance of the workpiece 200, and the risk that the workpiece 200 generates new poor appearance due to the fact that a hand of a human body directly contacts with the workpiece 200 can be avoided.

Specifically, in some embodiments, the workpiece 200 is a touch module, and the workpiece 200 can be applied to an electronic device such as a smart phone and a tablet computer, so that the electronic device has a touch sensing function. The workpiece 200 includes a body 210 and a flexible element 220 connected to each other, the body 210 may be a glass cover of a touch module, and the flexible element 220 may be a flexible circuit board (FPC) of the touch module. The detection of the appearance of the workpiece 200 may be understood as detecting whether or not the surface of the workpiece 200 has a poor appearance by human eyes or machine vision, and whether or not the appearance of the workpiece 200 meets a standard. For example, the surface of the detection main body 210 has appearance defects such as cracks and broken edges, and detects whether the regions of the workpiece 200 corresponding to the camera hole, the sensing hole, and the earpiece hole of the electronic device meet the standards of the electronic device, and whether the FPC is broken. Of course, in other embodiments, the workpiece 200 may be other modules or products that need to be supported and limited by the inspection fixture 100 so as to be manually held for appearance inspection.

In some embodiments, the inspection tool 100 includes a first tool plate 110 and a second tool plate 120 connected to each other, and the first tool plate 110 and the second tool plate 120 can rotate relatively to each other, so that the inspection tool 100 has a closed state or an open state. It should be noted that, in the present application, it is described that the detection fixture 100 is in an open state, or the first fixture plate 110 and the second fixture plate 120 are in an open state, and both the first inner side surface 116 and the second inner side surface 124 can be understood as being located on the same side of the workpiece. Further, when the detection fixture 100 is in the open state, the first fixture plate 110 and the second fixture plate 120 are substantially located on the same plane, or an included angle between the first fixture plate 110 and the second fixture plate 120 is large, for example, the included angle between the first fixture plate 110 and the second fixture plate 120 is larger than 150 ° and smaller than 180 °, so as to place the workpiece 200 on the detection fixture 100 or detect the surface of the workpiece 200 deviating from the detection fixture 100. When the detection jig 100 is in the closed state, or the first jig plate 110 and the second jig plate 120 are in the closed state, it can be understood that the first inner side surface 116 is opposite to the second inner side surface 124. Fig. 3 and fig. 4 are also referred to, in which fig. 3 illustrates a schematic view of the first jig plate 110 and the second jig plate 120 rotating relatively in some embodiments, and fig. 4 illustrates a schematic view of the first jig plate 110 and the second jig plate 120 in a closed state in some embodiments.

Further, in some embodiments, the edge of the second jig plate 120 connected to the first jig plate 110 is recessed to form the avoiding groove 121. Referring to fig. 2, the body 210 includes a first surface 211 and a second surface 212 opposite to each other, and the flexible element 220 includes a third surface 221 and a fourth surface 222 opposite to each other. When the inspection tool 100 is in the open state, the body 210 is limited on the first tool plate 110, and the flexible element 220 extends to the second tool plate 120 and is opposite to the avoiding groove 121, so as to inspect the appearance of the first surface 211 and the third surface 221. As shown in fig. 4, when the detection fixture 100 is in the closed state, the flexible element 220 rotates along with the second fixture plate 120 and is attached to the body 210, and the appearance of the fourth surface 222 can be detected through the avoiding groove 121.

In addition, the flexible element 220 is fragile, and when the first jig plate 110 and the second jig plate 120 rotate relatively to each other until being closed, the connection portion of the first jig plate 110 and the second jig plate 120 is bent to a large degree, which easily causes the flexible element 220 to be bent excessively and damaged. The avoiding groove 121 is provided, when the flexible element 220 rotates to be attached to the body 210 along with the second fixture, the avoiding groove 121 can reserve a bending space for the flexible element 220, so that the flexible element 220 can be bent more gently in the avoiding groove 121 at the joint of the first fixture plate 110 and the second fixture plate 120, i.e. the position where the bending degree is the greatest. Therefore, the avoiding groove 121 can reduce the bending degree of the flexible element 220 and avoid the flexible element 220 from being excessively bent and damaged.

Referring to fig. 2 and 4, it can be understood that the size of the avoiding groove 121 is slightly smaller than that of the flexible element 220 in the width direction of the avoiding groove 121 and the direction perpendicular to the boundary line of the first jig plate 110 and the second jig plate 120. So that the flexible element 220 can cross the avoiding groove 121 to abut against the second jig plate 120 through the body 210, and when the second jig plate 120 rotates relative to the first jig plate 110, the flexible element 220 can be driven to rotate to be attached to the body 210. Of course, the size of the avoiding groove 121 cannot be too small, otherwise, when the detection fixture 100 is in the closed state, the second fixture plate 120 is easy to shield the flexible element 220, which affects the appearance detection of the fourth surface 222.

Further, in some embodiments, the avoiding groove 121 extends along the boundary line of the first jig plate 110 and the second jig plate 120, and the size of the avoiding groove 121 is slightly smaller than that of the second jig plate 120 in a direction parallel to the boundary line of the first jig plate 110 and the second jig plate 120. Further, the length dimension of the relief groove 121 is greater than or equal to the length dimension of the workpiece 200. Therefore, when the flexible element 220 is connected to different positions of the body 210, that is, when the detection jig 100 detects different workpieces 200, as long as the flexible element 220 is connected to one side of the body 210 close to the second jig plate 120, the avoiding groove 121 can be opposite to the flexible element 220, so as to detect the appearance of the fourth surface 222 when the detection jig 100 is in the closed state. In other words, the length of the avoiding groove 121 is long enough to enable the inspection jig 100 to be adapted to different workpieces 200.

Referring to fig. 1 and 2, the first jig plate 110 is not limited to limit the workpiece 200, and in some embodiments, the first jig plate 110 includes a plate 111 and a stopper 113, the stopper 113 is disposed on one side of the plate 111, and the stopper 113 is disposed along the periphery of the plate 111. When the body 210 is placed on the jig plate, the stoppers 113 are located on three sides of the plate 111 to limit the body 210, thereby preventing the body 210 from separating from the inspection jig 100. Certainly, the stopper 113 is not disposed on one side of the body 210 close to the second fixture plate 120, so as to prevent the stopper 113 from affecting the closing of the first fixture plate 110 and the second fixture plate 120, and when the detection fixture 100 is in the closed state, the second fixture plate 120 can limit one side of the body 210 connected to the flexible element 220.

Further, the connection position of the flexible element 220 and the body 210 of different workpieces 200 may be different, and the flexible element 220 may be connected to the side of the body 210 away from the second jig plate 120. In order to improve the applicability of the detection jig 100, in some embodiments, referring to fig. 2 and 4, on the edge of the body 210 away from the second jig plate 120, the stoppers 113 are disposed at intervals to form first receiving grooves 114, the periphery of the plate body 111 is recessed to form the first viewing port 112, and the first viewing port 112 is opposite to the first receiving grooves 114. Therefore, if the flexible element 220 is connected to the body 210 at a position opposite to the first receiving groove 114, the flexible element 220 can be received in the first receiving groove 114. When the detection fixture 100 is in the closed state, the appearance of the flexible element 220 can be detected through the first observation port 112 on the side of the plate body 111 away from the second fixture plate 120, so that the detection fixture 100 can be adapted to more different elements.

Furthermore, in some embodiments, the stoppers 113 may be disposed at intervals on the edge of the plate 111 away from the second jig plate 120 to form a second receiving groove 115 spaced from the first receiving groove 114, the edge of the second jig plate 120 away from the body 210 is recessed to form a second viewing port 122, and the second viewing port 122 is opposite to the second receiving groove 115. Therefore, if the flexible element 220 is connected to the body 210 at a position opposite to the second receiving groove 115, the flexible element 220 can be received in the second receiving groove 115. When the inspection tool 100 is in the closed state, the appearance of the flexible element 220 can be inspected through the second observation opening 122, so that the inspection tool 100 can be adapted to more different elements. In addition, in some embodiments, the first receiving groove 114 and the second receiving groove 115 are respectively located at two corners of the board body 111, so that the flexible element 220 is connected to different corners of the body 210, and the inspection jig 100 can both receive and meet the inspection requirement of the flexible element 220, thereby improving the applicability of the inspection jig 100.

Referring to fig. 2 and 4, in some embodiments, the second fixture plate 120 further has a slot 123, the slot 123 is connected to one end of the avoiding slot 121, and an extending direction of the slot 123 is perpendicular to an extending direction of the avoiding slot 121. Thus, when the detection fixture 100 is in the closed state, a partial region of the body 210 can be exposed from the slot 123, for example, a region of the body 210 opposite to the earpiece hole of the electronic device is opposite to the slot 123, and the appearance of the partial region of the body 210 can be detected through the slot 123, so as to meet more detection requirements of the workpiece 200.

It should be noted that, in the present application, it is described that a partial region of the board body 111 is opposite to a partial region of the second jig board 120, and it can be understood that when the detection jig 100 is in the closed state, that is, the second jig board 120 is opposite to the surface of the board body 111, the board body 111 is opposite to the two regions of the second jig board 120.

Referring to fig. 1 again, the connection manner of the first jig plate 110 and the second jig plate 120 is not limited, as long as the first jig plate 110 and the second jig plate 120 can rotate relatively. In some embodiments, the inspection jig 100 further includes a rubber strip 130, and the rubber strip 130 is adhered to the first jig plate 110 and the second jig plate 120 at two ends of the avoiding hole. The adhesive tape 130 is made of a flexible material, and can realize the relative rotation between the first jig plate 110 and the second jig plate 120. Of course, in other embodiments, the first jig plate 110 and the second jig plate 120 may be connected by a hinge, a rotating shaft, or the like. The adhesive tape 130 is adopted for connection, so that the connection cost is low, the maintenance of the connection part is more convenient, and only the adhesive tape 130 needs to be replaced.

In addition, in some embodiments, the detection fixture 100 further includes a teflon film (not shown) covering the surfaces of the plate body 111, the stop block 113, the second fixture plate 120, and the adhesive strip 130. The teflon film has good wear resistance and durability, can prolong the service life of the detection jig 100, and simultaneously prevents the workpiece 200 from being scratched by friction damage on the surface of the detection jig 100. The teflon film has a smooth and soft surface, is not easy to adsorb broken filament foreign matters, and can reduce the risks of poor appearance such as scratching or edge and corner breakage in the process of surface friction between the workpiece 200 and the detection jig 100.

Further, in some embodiments, the stopper 113 is made of silicon gel, and the plate 111 and the second jig plate 120 are made of polyvinyl chloride (PVC). Silica gel is elastic material, regards silica gel as dog 113, rocks on plate 111 when colliding with dog 113 when body 210, and dog 113 can cushion body 210's impact, avoids body 210 to damage because of the collision. Silica gel and PVC material weight are all lighter, can greatly reduce detection tool 100's weight to reduce artifical handheld detection tool 100 and examine time measuring fatigue, promote artifical detection efficiency.

In addition, the silica gel, the PVC and the teflon all have good insulating properties, so that the manufactured detection jig 100 can well isolate the workpiece 200 from static electricity, and the workpiece 200 placed on the detection jig 100 is prevented from being damaged due to the static electricity. Specifically, the impedance value of the surface of the detection jig 100 made of the material is 1 × 10⁶-1*10⁹And omega, the impedance value standard of the touch module jig is met, and the workpiece 200 can be prevented from being damaged due to static electricity.

Furthermore, the silica gel, the PVC and the teflon are low in material cost and can be prepared from production waste, which is beneficial to reducing the manufacturing cost of the detection jig 100. For example, a silicone pad in the production waste is used as the stopper 113, and a waste plastic plate made of PVC Optical Cement (OCA) is used as the plate body 111 and the second jig plate 120. Meanwhile, the second jig plate 120, the first jig plate 110 and the adhesive tape 130 can be manufactured independently, and when one of the second jig plate, the first jig plate and the adhesive tape is damaged, only one of the second jig plate, the first jig plate and the adhesive tape needs to be replaced, so that the maintenance cost of the detection jig 100 is reduced.

It can be understood that the first surface 211 and the third surface 221 can be detected when the first jig plate 110 and the second jig plate 120 are in the open state. When the first jig plate 110 and the second jig plate 120 are closed, the fourth surface 222 can be detected through the avoiding groove 121. When the inspection tool 100 is turned over, the second tool plate 120 can support the body 210, so that the second surface 212 can be inspected when the first tool plate 110 and the second tool plate 120 are opened again. Therefore, when the detection jig 100 is used for detecting the workpiece 200, the detection of each surface of the workpiece 200 can be completed without the contact of the human hand with the workpiece 200, and the situation that the human hand contacts the workpiece 200 to cause a new bad phenomenon to be generated on the workpiece 200 is avoided.

Referring to fig. 5, fig. 5 is a schematic diagram of a detection method in some embodiments. The appearance of each surface of the workpiece 200 can be detected by using the detection jig 100 according to any one of the above embodiments according to the following detection method. Specifically, the detection method comprises the following steps:

s110, referring to fig. 1 and 2, the workpiece 200 is placed on the inspection jig 100.

The detection fixture 100 is in an open state, the plate 111 bears the body 210, the stoppers 113 are arranged along the circumferential direction of the body 210 to limit the body 210, the flexible element 220 is opposite to the avoiding groove 121, and the flexible element 220 crosses the avoiding groove 121 and contacts the second fixture plate 120. The third surface 221 is attached to the plate 111, and the fourth surface 222 is in contact with the second jig plate 120.

S120, the first jig plate 110 is kept in an open state relative to the second jig plate 120, so that the first surface 211 and the third surface 221 are exposed out of the detection jig 100, thereby facilitating the detection of the appearance of the first surface 211 and the third surface 221 on the side of the workpiece 200 departing from the detection jig 100.

S130, the first fixture plate 110 and the second fixture plate 120 are rotated relatively to be in a closed state, and the detection fixture 100 is in the closed state, so that the fourth surface 222 is exposed from the avoiding groove 121 to the second fixture plate 120, thereby facilitating the detection of the appearance of the fourth surface 222 through the avoiding groove 121 from the side of the second fixture plate 120 departing from the first fixture plate 110.

S140, the inspecting tool 100 is turned over, so that the body 210 is stacked on the second tool plate 120. In other words, after the inspection jig 100 is turned over, the body 210 is transferred from the state of being carried by the plate 111 to the state of being carried by the second jig plate 120.

S150, the first jig plate 110 is rotated to an open state relative to the second jig plate 120, so that the second surface 212 is exposed to the side of the second inner side surface 124 of the second jig plate 120, thereby facilitating the detection of the appearance of the second surface 212 at the side of the body 210 departing from the second jig plate 120.

By the detection method, the appearance of the workpiece 200 is detected by the detection jig 100, the detection of each surface of the workpiece 200 can be completed without the direct contact between the hand of a human body and the workpiece 200, and the phenomenon that the new appearance of the workpiece 200 is poor in the detection process is avoided to the greatest extent.

In some embodiments, after step S150, the detection method further includes: the inspection jig 100 is closed, and the inspection jig 100 is turned over again, so that the board 111 carries the body 210. The detection jig 100 is opened, and the workpiece 200 is removed. The workpiece 200 is placed on the detection fixture 100, and the workpiece 200 is taken down from the detection fixture 100, so that the workpiece 200 can be sucked by the vacuum suction ball, and the phenomenon of poor appearance caused by direct contact between the hand of a human body and the workpiece 200 is avoided.

It should be noted that, in the present application, when the body 210 is supported on one of the plate 111 or the second jig plate 120, the opening or closing of the detection jig 100 can be understood as fixing one of the plate 111 and the second jig plate 120 supporting the body 210 and rotating the other one to prevent the body 210 from being damaged due to being separated from the detection jig 100 during the opening or closing process. For example, in step S130, the body 210 is carried on the plate 111, and the closing detection fixture 100 can be understood as rotating the second fixture plate 120 relative to the first fixture plate 110. In step S140, after the inspection tool 100 is turned over, the body 210 is supported on the second tool plate 120, and the inspection tool 100 is opened, which is to be understood as rotating the first tool plate 110 relative to the second tool plate 120.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
