In order to simplify the disclosure of the present application, specific example components and arrangements are described below. Of course, they are merely examples and are not intended to limit the present application. Further, the present application may repeat reference numerals and/or letters in the various examples. This repetition is for the purpose of simplicity and clarity and does not in itself dictate a relationship between the various embodiments and/or configurations discussed. In addition, examples of various specific processes and materials are provided herein, but one of ordinary skill in the art may recognize the applicability of other processes and/or the use of other materials.
Next, the spot inspection tool 100 of the fingerprint module 101 according to the embodiment of the present application is described with reference to the drawings.
As shown in fig. 1 and 3, the fingerprint module 101 includes a sensor element 1011 and a reinforcing steel sheet 1012, the sensor element 1011 is disposed on one side of the reinforcing steel sheet 1012, and the sensor element 1011 is connected to the reinforcing steel sheet 1012. For example, in the example of fig. 1 and 3, the sensor element 1011 is disposed on one side of the width of the reinforced steel sheet 1012, and the sensor element 1011 can have a finger-picking position 1011a, so that the user can place a finger on the finger-picking position 1011a in the using process, the fingerprint module 101 can identify the fingerprint of the user, and meanwhile, when the fingerprint module 101 is on a production line, the fingerprint module 101 can be conveniently picked and placed by an operator through the finger-picking position 1011 a.
As shown in fig. 1, the spot inspection tool 100 includes a spot inspection substrate 1, the spot inspection substrate 1 has an operation surface 10, for example, an upper surface of the spot inspection substrate 1 may be formed as the operation surface 10. A plurality of point inspection grooves 11 are formed on the operation surface 10, the plurality of point inspection grooves 11 are arranged at intervals, and the point inspection grooves 11 can be formed by recessing a part of the operation surface 10; point is examined recess 11 and is suitable for with fingerprint module 101 looks adaptation to screening and the fingerprint module 101 that the overall dimension of point is examined recess 11 suits. The spot inspection groove 11 comprises a first spot inspection groove 111 and a second spot inspection groove 112, the shape of the first spot inspection groove 111 is suitable for being matched with the sensor assembly 1011, and the shape of the second spot inspection groove 112 is suitable for being matched with the reinforced steel sheet 1012.
For example, in the spot inspection process, an operator can match the fingerprint module 101 with the spot inspection groove 11, match the sensor assembly 1011 with the first spot inspection groove 111, match the reinforcing steel sheet 1012 with the second spot inspection groove 112, and can eliminate the fingerprint module 101 which cannot be assembled with the spot inspection groove 11 through screening of the spot inspection groove 11, and the fingerprint module 101 and the spot inspection groove 11 have larger difference in the outer dimensions and are not in accordance with requirements; but also can get rid of and assemble to some and examine recess 11, nevertheless with some to examine the fingerprint module 101 that the interval between the lateral wall of recess 11 is great and surpass the allowed error, these fingerprint module 101 also with some the physical dimension of examining recess 11 difference greatly, do not conform to the requirement. From this, can select can assemble to some and examine recess 11, and with some fingerprint module 101 that the interval between the lateral wall of examining recess 11 is in the allowable error range, these fingerprint module 101's overall dimension meets the requirements.
Wherein, can assemble to the fingerprint module 101 of some recess 11 of examining, the interval between its periphery wall and some recess 11 lateral walls of examining can be judged through operation personnel sense organ (for example naked eye observation, sense of touch etc.) and/or measuring tool. For example, when the distance between the peripheral wall of the fingerprint module 101 and the side wall of the spot inspection groove 11 is large, an operator can judge that the requirement is not met by naked eyes, and then the measurement can be performed without using a measuring tool, so that the spot inspection efficiency is improved, the spot inspection time is saved, and the spot inspection process is more economical; for another example, when the distance between the outer peripheral wall of the fingerprint module 101 and the sidewall of the spot inspection groove 11 is small, the operator can use the measuring tool to measure, and compare the measurement result with the allowable error, if the measurement result is within the allowable error range, the measurement result is satisfactory, otherwise, the measurement result is unsatisfactory.
It is understood that the outer dimensions of the spot inspection groove 11 may include the length, width and depth of the spot inspection groove 11.
Compared with some technologies, an operator directly measures the overall dimension of the fingerprint module 101 by using a measuring tool such as a caliper to judge whether the fingerprint module 101 meets the requirement, the number of actions of the operator is large, the action amplitude is large, and the point inspection time is long, for example, the operator needs to turn over the fingerprint module for many times to measure the dimension of the fingerprint module in the point inspection process, and the point inspection precision of the operator is poor; frock 100 is examined to fingerprint module 101's point in this application need not the operator fingerprint module 101 that overturns many times, has reduced operator action quantity and action range, can effectively save the point and examine the time, promotes the point and examine efficiency, is favorable to promoting the point simultaneously and examines the precision, guarantees the accuracy of point examination result.

Therefore, the length, width and thickness of the reinforced steel sheet 1012 meet the requirements, and the external dimension of the reinforced steel sheet 1012 meets the requirements.
For example, for the fingerprint module 101 that can be assembled into the spot inspection groove 11, in the length direction of the elongated slot 11b, one end of the reinforced steel sheet 1012 abuts against the side wall of the second spot inspection groove 112, the interval between the other end of the reinforced steel sheet 1012 and the side wall of the second spot inspection groove 112 is not more than 0.3mm, that is, the length of the reinforced steel sheet 1012 meets the requirement, in the width direction of the elongated slot 11b, one end of the reinforced steel sheet 1012 abuts against the side wall of the second point inspection groove 112, the interval between the other end of the reinforced steel sheet 1012 and the side wall of the second point inspection groove 112 is not more than 0.3mm, that is, the width of the reinforcing steel sheet 1012 meets the requirement, and in the depth direction of the elongated slot 11b, the bottom surface of the reinforcing steel sheet 1012 stops against the bottom wall of the second point inspection groove 112, and the interval between the top surface of the reinforcing steel sheet 1012 and the upper end edge of the second point inspection groove 112 is not more than 1mm, that is, the thickness of the reinforcing steel sheet 1012 meets the requirement.
Similarly, the spot inspection of the sensor element 1011 by the first spot inspection groove 111 is also the same, and the first spot inspection groove 111 may be formed as a square groove 11a, and the allowable error may be 0.3mm in both the length direction and the width direction of the square groove 11a, and may be 1mm in the depth direction of the square groove 11 a. It can be understood that when the rail reinforcing steel sheet 1012 and the sensor assembly 1011 both meet the requirements, the fingerprint module 101 meets the requirements.
In some embodiments, the depth of the first spot inspection groove 111 is greater than the depth of the second spot inspection groove 112, that is, the depth of the first spot inspection groove 111 recessed from the operating surface 10 is greater than the depth of the second spot inspection groove 112 recessed from the operating surface 10; because the bottom surface of sensor subassembly 1011 and the bottom surface of reinforcement steel sheet 1012 are not on same horizontal plane to when fingerprint module 101 cooperates with the point and examines recess 11, be convenient for guarantee that sensor subassembly 1011's bottom surface ends to examine the diapire of recess 111 in the first point, the bottom surface of reinforcement steel sheet 1012 ends to examine the diapire of recess 112 in the second point simultaneously, avoid the unsettled setting of reinforcement steel sheet 1012, lead to the operator to examine the in-process fragile fingerprint module 101 in the point, and then guaranteed the practicality of point and examined recess 11.
