[0042] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0045] In the manufacturing industry, fixtures ensure the accuracy and consistency of products throughout the manufacturing process by providing stable support. Typically, fixtures consist of multiple fixing blocks, each of which is designed to provide the necessary support and positioning for the product in a specific position, thereby ensuring the accuracy of subsequent testing or assembly of the product.

[0046] However, in actual operation, operators may make operating errors or fail to strictly follow the standard operating procedures to assemble the fixing blocks, resulting in poor fixing effects of the products. In this case, the products may shift during subsequent testing or assembly processes, which in turn affects the accuracy of testing or assembly, thereby increasing the defective product rate.

[0047] To this end, the present application proposes a fixing detection device and system, which aims to solve the technical problem that the fixing effect of the product is poor due to the operator's operating errors or failure to strictly follow the standard operating procedures to assemble the fixing blocks.

[0048] In one embodiment of the present application, reference Figure 1 The fixed detection device is applied to the fixed detection system, the fixed detection system is used to detect whether the fixed block is successfully assembled, the fixed detection system includes a light emitting component 10, the fixed detection device is used to be pre-installed on the fixed block, and the fixed detection device includes:

[0049] A substrate 20, wherein the substrate 20 has a first light-emitting hole 30, a second light-emitting hole 40 and an optical path structure 50; light entering through the first light-emitting hole 30 is emitted from the second light-emitting hole 40 after passing through the optical path structure 50;

[0050] The first light-emitting hole 30 is used for allowing the light emitted by the light-emitting assembly 10 to enter the first light-emitting hole 30 when the fixing block is installed at the target position;

[0051] A light recognition component 60 is disposed on the base 20, and is used to output a corresponding light detection signal when recognizing that light is incident through the first light-emitting hole 30;

[0052] A main control circuit 70, wherein the main control circuit 70 is electrically connected to an output end of the light recognition component 60;

[0053] The main control circuit 70 is used to determine that the fixing block is successfully assembled when the light detection signal is received; the main control circuit 70 is also used to determine that the fixing block is not successfully assembled when the light detection signal is not received within a preset time.

[0054] In this embodiment, optionally, the light emitting component 10 can be implemented using a laser diode, which can generate a highly concentrated light beam so that the illumination intensity remains basically unchanged when the light is transmitted to the substrate 20, which helps to improve the accuracy of the light recognition component 60 in identifying the incident light and avoid interference from ambient light sources.

[0055] Optionally, the light emitting component 10 can also be implemented using an infrared LED, while the light identification component 60 is correspondingly implemented using an infrared sensor. Since the infrared sensor is only used to identify the wavelength of infrared light and cannot identify the wavelengths of other light, the light emitting component 10 uses an infrared LED and the light identification component 60 uses an infrared sensor to help improve the accuracy of identifying light entering through the first light-emitting hole 30 and avoid interference from ambient light sources.

[0056] In one embodiment, the optical recognition component 60 is disposed in the hole of the second light-emitting hole 40, or corresponds to the position of the second light-emitting hole 40, so that the light emitted through the second light-emitting hole 40 is directly emitted to the optical recognition component 60, which helps to improve the accuracy of the optical recognition component 60 in recognizing the light entering through the first light-emitting hole 30. Among them, the optical recognition component 60 can be implemented by a photodiode or a photoresistor. The photodiode generates a current or voltage when receiving light. The main control circuit 70 determines that the fixed block is successfully assembled after detecting the current or voltage generated by the photodiode; the resistance of the photoresistor decreases when exposed to light. The main control circuit 70 determines that the fixed block is successfully assembled after detecting that the resistance or voltage of the photoresistor decreases.

[0057] In another embodiment, the optical recognition component 60 is disposed in the substrate 20. When light enters through the first light-emitting hole 30, part of the light will propagate in the substrate 20. The optical recognition component 60 is used to determine that the light enters through the first light-emitting hole 30 when the divergent light is captured. It is understandable that since the light intensity of the divergent light is low, it is necessary to increase the sensitivity of the optical recognition component 60. For example, when the light-emitting component 10 adopts a photoresistor, the sensitivity of the photoresistor is increased so that the resistance value of the photoresistor becomes smaller when the light is weak; when the light-emitting component 10 adopts a photodiode, the sensitivity of the photodiode is increased so that the photodiode generates a voltage or current when the light is weak. When the light is infrared light, the optical recognition component 60 can be implemented using an infrared sensor.

[0058] In this embodiment, the base 20 may include a cylindrical shell, and the shape of the cylindrical shell may be any one of a cylindrical, polygonal, square or rectangular column. The first light-emitting hole 30 and the second light-emitting hole 40 are holes respectively arranged on the cylindrical shell. The optical path structure 50 is located in the cylindrical shell. The first light-emitting hole 30 is for the light emitted by the light emitting component 10 to enter the cylindrical shell, and the optical path structure 50 is used to guide the incident light to propagate along a predetermined path, thereby guiding the light to be emitted through the second light-emitting hole 40.

[0059] The optical path structure 50 may include optical elements such as reflective surfaces, lenses, and prisms, which are used to refract or reflect the incident light, so as to ensure that the light can propagate along a predetermined path and finally be emitted through the second light-emitting hole 40. In one embodiment, the optical path structure 50 may be implemented by using multiple reflective surfaces, and the light incident through the first light-emitting hole 30 is emitted from the second light-emitting hole 40 through the reflection effect of the multiple reflective surfaces. For example, referring to Figure 3 The optical path structure 50 includes a first reflecting surface 51 and a second reflecting surface 52 provided on the substrate 20; the first reflecting surface 51 and the second reflecting surface 52 are arranged opposite to each other, the central axis of the first light-emitting hole 30 and the first reflecting surface 51 have a first intersection, the central axis of the second light-emitting hole 40 and the second reflecting surface 52 have a second intersection, the light entering through the first light-emitting hole 30, after being reflected by the first intersection, passes through the second intersection, and the second intersection emits the received light through the second light-emitting hole 40.

[0060] It can be understood that the first intersection is the contact point between the light incident through the first light hole 30 and the first reflecting surface 51, and the second intersection is the contact point between the light reflected by the first intersection and the second reflecting surface 52. The first reflecting surface 51 is used to reflect the light incident through the first light hole 30 to the second reflecting surface 52, and the second reflecting surface 52 then emits the light through the second light hole 40.

[0061] In another embodiment, the optical path structure 50 may also be implemented by a refractive structure composed of at least one lens or prism, which refracts the incident light to ensure that the light can propagate along a predetermined path and finally be emitted through the second light-emitting hole 40. Figure 4 The light entering through the first light-emitting hole 30 is refracted when passing through one end of the refractive structure. The light is refracted again after total reflection inside the refractive structure and is finally aligned with the second light-emitting hole 40 so that the refracted light is emitted through the second light-emitting hole 40.

[0062] In this embodiment, the main control circuit 70 can be implemented by a main controller, such as an MCU (Microcontroller Unit), a DSP (Digital Signal Process), an FPGA (Field Programmable Gate Array), a SOC (System On Chip), etc.

[0063] In this embodiment, the preset time is the maximum time required to assemble the fixed block. If the operator fails to assemble the fixed block successfully within the preset time, it means that the operator did not assemble according to the standard operating procedures, resulting in the failure of the fixed block to be assembled successfully. The user can set the preset time according to the actual assembly situation of the fixed block.

[0064] In this embodiment, the target position is the position where the fixed block should be installed in the production line, so as to provide necessary support and positioning for the product. The light emitting assembly 10 is pre-installed at a predetermined position so that when the fixed block is installed at the target position, the light emitting end of the light emitting assembly 10 corresponds to the position of the first light emitting hole 30. In practical applications, before the user performs final assembly or testing of the product, the user pre-completes the assembly of the fixed block of a manufacturing process or production line, and pre-installs the fixed detection device on the fixed block after the assembly is completed. The user can ensure that the first light emitting hole 30 corresponds to the position of the light emitting end of the light emitting assembly 10 by constantly adjusting the position of the fixed detection device and the position of the light emitting assembly 10, thereby effectively determining the optimal position of the fixed block for pre-installing the fixed detection device and the predetermined position of the light emitting assembly 10 for pre-installation. According to the optimal position of the fixed block for pre-installing the fixed detection device and the predetermined position of the light emitting assembly 10 for pre-installation, the user can pre-install the fixed detection device on other fixed blocks in the same manufacturing process or production line to detect the assembly conditions of the fixed blocks of multiple manufacturing processes or production lines.

[0065] In this embodiment, the fixed detection device of the present application also includes an alarm module 80, which is electrically connected to the main control circuit 70. The alarm module 80 can be implemented by a sound alarm or a light alarm. When the main control circuit 70 determines that the fixed block has not been assembled successfully, it controls the alarm module 80 to emit a sound alarm or a light alarm to prompt the operator that the current fixed block has not been assembled successfully.

[0066] The fixed detection device of the present application includes a base 20 and an optical recognition component 60. The base 20 has a first light-emitting hole 30, a second light-emitting hole 40 and an optical path structure 50. The light entering through the first light-emitting hole 30 is emitted from the second light-emitting hole 40 after passing through the optical path structure 50. The first light-emitting hole 30 is used to correspond to the position of the light-emitting end of the optical emitting component 10 when the fixed block is installed at the target position, so that the light emitted by the optical emitting component 10 can enter the first light-emitting hole 30. The optical recognition component 60 is used to output a corresponding light detection signal when recognizing that light is emitted through the first light-emitting hole 30. When the main control circuit 70 receives the light detection signal, it determines that the fixed block is successfully assembled, and when the light detection signal is not received within the preset time, it determines that the fixed block is not successfully assembled.

[0067] With such a configuration, in actual application, when the operator fails to assemble the fixed block according to standard operation, resulting in the operator failing to assemble the fixed block successfully within the preset time, the fixed detection device of the present application determines that the fixed block has not been assembled successfully, and can issue an alarm to remind the operator that the fixed block has not been assembled according to the standard operation process. The operator corrects the error in time after receiving the prompt, thereby ensuring the fixing effect of the product and ensuring that the accuracy of the product in subsequent testing or assembly is not affected.

[0068] In an embodiment of the present application, optionally, the first reflection surface 51 and the second reflection surface 52 of the above embodiment can both be implemented by using a reflection mirror. Figure 5 The base 20 has a reflection cavity 23, and the fixed detection device includes a first reflection mirror 511 and a second reflection mirror 521. The first reflection mirror 511 and the second reflection mirror 521 are respectively arranged in the reflection cavity 23. The first reflection surface 51 is the reflection surface of the first reflection mirror 511, and the second reflection surface 52 is the reflection surface of the second reflection mirror 521. The reflection surface of the first reflection mirror 511 and the reflection surface of the second reflection mirror 521 are arranged opposite to each other. The reflection surface of the first reflection mirror 511 is used to reflect the light incident through the first light-emitting hole 30 to the reflection surface of the second reflection mirror 521, and the reflection surface of the second reflection mirror 521 is used to reflect the light reflected by the first reflection mirror 511 out through the second light-emitting hole 40. The reflection cavity 23 is the inner cavity of the base 20.

[0069] Optionally, the first reflecting surface 51 and the second reflecting surface 52 in the above embodiment can also be implemented by using a wall surface coated with a metal coating. Figure 6The substrate 20 has a reflective cavity 23, the substrate 20 has an upper inner wall surface 512 and a lower inner wall surface 522, the first reflective surface 51 and the second reflective surface 52 are respectively the upper inner wall surface 512 and the lower inner wall surface 522, the upper inner wall surface 512 and the lower inner wall surface 522 correspond to the first light-emitting hole 30 and the second light-emitting hole 40 respectively, and the upper inner wall surface 512 and the lower inner wall surface 522 are both coated with a metal coating so that the upper inner wall surface 512 and the lower inner wall surface 522 can reflect light.

[0070] Furthermore, the angle between the central axis of the first light-emitting hole 30 and the first reflective surface 51 is 45 degrees; the angle between the central axis of the second light-emitting hole 40 and the second reflective surface 52 is 45 degrees. The 45-degree angle allows the light to be turned 90 degrees between the first reflective surface 51 and the second reflective surface 52 without requiring an additional straight-line propagation distance, thereby allowing the entire light path to be compressed into a very limited space, which is conducive to the miniaturization design of the fixed detection device of the present application.

[0071] In one embodiment of the present application, reference Figure 7 , the fixed detection device also includes:

[0072] An action detection module 90, the action detection module 90 is used to output an action detection signal when detecting that the fixing block is assembled;

[0073] The output end of the motion detection module 90 is electrically connected to the main control circuit 70, and the main control circuit 70 is used to perform a first timing when receiving the motion detection signal;

[0074] The main control circuit 70 is used to obtain the first timing time when receiving the light detection signal, and determine whether the fixing block is successfully assembled according to the first timing time.

[0075] In this embodiment, the motion detection module 90 can be implemented by an acceleration sensor, and when the fixed block is assembled, displacement or vibration occurs, and the acceleration sensor outputs a signal when the vibration or displacement is detected. Optionally, the motion detection module 90 can also be implemented by a gyroscope, and when the fixed block is assembled, tilt or rotation occurs, and the gyroscope outputs a signal when the tilt or rotation of the fixed block is detected.

[0076] In one embodiment, when the operator assembles the fixed block only according to part of the process in the standard operating procedure, the time required to assemble the fixed block is less than the shortest time required to assemble the fixed block according to the standard operating procedure. In this regard, when the main control circuit 70 receives the light detection signal within the shortest time required to assemble the fixed block, that is, the first timing time is less than the shortest time required to assemble the fixed block, it is determined that the fixed block has not been assembled successfully, and when the main control circuit 70 receives the light detection signal after the shortest time required to assemble the fixed block, that is, the first timing time is greater than or equal to the shortest time required to assemble the fixed block, it is determined that the fixed block has been assembled successfully. With such a configuration, the fixed detection device of the present application can identify an incomplete assembly process, thereby issuing an alarm to the operator when the operator does not assemble according to the complete assembly process, so as to avoid potential quality problems during the assembly process.

[0077] In another embodiment, when the operator assembles the fixed block according to an incorrect operating procedure, the operator cannot successfully assemble the fixed block within the longest time required to assemble the fixed block according to the standard operating procedure. In this regard, when the main control circuit 70 receives the light detection signal within the longest time required to assemble the fixed block, that is, when the main control circuit 70 is less than the preset time during the first timing, it determines that the fixed block is successfully assembled, and when the light detection signal is not received within the longest time required to assemble the fixed block, that is, when the main control circuit 70 has not received the light detection signal when the first timing time is equal to the preset time, it determines that the fixed block is not successfully assembled. In this way, the fixed detection device of the present application can identify invalid or non-compliant assembly processes, and can alarm the operator when the operator assembles according to an invalid or non-compliant operating procedure, so as to avoid potential quality problems during the assembly process.

[0078] Furthermore, when the main control circuit 70 determines that the fixing block is not assembled successfully, the first timing is reset. With such a configuration, in practical applications, when the fixing detection device of the present application determines that the fixing block is not assembled successfully, the timing is reset to allow the operator to reassemble the fixing block, and the assembly status of the operator is re-detected to ensure that each assembly can be verified and corrected in a timely manner.

[0079] The present application also proposes a fixed detection system, comprising: a light emitting component 10, used to emit light when working; and the fixed detection device described above, wherein after the fixed block is installed at the target position, the first light-emitting hole 30 of the fixed detection device corresponds to the position of the light emitting end of the light emitting component 10, so as to receive the light emitted by the light emitting component 10.

[0080] It is worth noting that since the fixed detection system of the present application is based on the above-mentioned fixed detection device, the embodiments of the fixed detection system of the present application include all technical solutions of all embodiments of the above-mentioned fixed detection device, and the technical effects achieved are also exactly the same, which will not be repeated here.

[0081] In one embodiment of the present application, the fixed detection device is correspondingly provided in plurality, and is used to be pre-installed on a plurality of the fixed blocks so that each of the fixed blocks is pre-installed with a fixed detection device. After the fixed detection device is installed at the target position, the first light-emitting hole 30 of the fixed detection device corresponds to the position of the light-emitting end of the light-emitting component 10, so as to receive the light emitted by the light-emitting component 10;

[0082] Or, the first light-emitting hole 30 of the fixed detection device on the fixed block that is assembled later corresponds to the second light-emitting hole 40 of the fixed detection device on the fixed block that is assembled earlier, so as to receive light emitted through the second light-emitting hole 40 of the fixed detection device on the fixed block that is assembled earlier.

[0083] In this embodiment, when the first fixed block in the assembly sequence is installed at the target position, the first light-emitting hole 30 of the pre-installed fixed detection device corresponds to the position of the light-emitting end of the light-emitting assembly 10, so that the light emitted by the light-emitting assembly 10 enters the first light-emitting hole 30 of the pre-installed fixed detection device of the first fixed block in the assembly sequence. When the next fixed block in the assembly sequence is installed at the target position, the first light-emitting hole 30 of the pre-installed fixed detection device corresponds to the position of the second light-emitting hole 40 of the pre-installed fixed detection device on the previous fixed block in the assembly sequence, so that the light emitted by the pre-installed fixed detection device on the previous fixed block in the assembly sequence through its second light-emitting hole 40 enters the first light-emitting hole 30 of the fixed detection device on the next fixed block in the assembly sequence.

[0084] It should be noted that, since the first light-emitting hole 30 of the fixed detection device of the later fixed block in the assembly sequence only corresponds to the position of the second light-emitting hole 40 of the fixed detection device pre-installed in the previous fixed block in the assembly sequence, when at least one fixed block in the previous assembly sequence has not been assembled, even if the later fixed block in the assembly sequence has been assembled successfully, the main control circuit 70 of the pre-installed fixed detection device cannot receive the light detection signal. Therefore, when the main control circuit 70 of each fixed detection device does not receive the light detection signal after the preset time required for assembling the fixed block, it is determined that the fixed block has not been assembled successfully, or at least one fixed block in the previous assembly sequence has not been assembled.

[0085] Through the above arrangement, when any fixed block is successfully assembled, its pre-installed fixed detection device receives the light from the light emitting assembly or the light emitted from the second light-emitting hole 40 of the fixed detection device on the previous fixed block in the assembly order, and transmits the light to the fixed detection device on the next fixed block to form an optical transmission link. In practical applications, when the fixed detection device pre-installed on the fixed block recognizes that the operator has not successfully assembled the fixed block within the preset time required to assemble the fixed block, an alarm is issued to prompt the operator that the current fixed block has not been assembled successfully, or that there is a fixed block that has not been assembled in the previous assembly order, so that the operator can find and correct the error in time, thereby reducing the phenomenon of assembly errors caused by improper manual operation and improving the assembly quality of the fixed block.

[0086] It can be understood that since the above-mentioned embodiment in which the light recognition component 60 is disposed in the second light emitting hole 40 or corresponds to the position of the second light emitting hole 40, it will hinder the light from being emitted through the second light emitting hole 40. Therefore, the light recognition component 60 of this embodiment is disposed in the base 20, and when the divergent light is captured, it is determined that the light is emitted through the first light emitting hole 30, so as to avoid the light recognition component 60 hindering the light from being emitted through the second light emitting hole 40.

[0087] It is understandable that in actual applications, before the user performs final assembly or testing of the product, the user completes the assembly of multiple fixed blocks of a manufacturing process or production line in advance, and pre-installs multiple fixed detection devices on the multiple fixed blocks in sequence after the assembly is completed. By continuously adjusting the positions of the multiple fixed detection devices, it is ensured that the first light-emitting hole 30 of each fixed detection device corresponds to the position of the second light-emitting hole 40 of the fixed detection device of the previous fixed block in the assembly sequence, or corresponds to the position of the light-emitting end of the light-emitting assembly 10, and the second light-emitting hole 40 corresponds to the position of the first light-emitting hole 30 of the fixed detection device on the next fixed block in the assembly sequence, thereby effectively determining the optimal position of each fixed block for pre-installing the fixed detection device. The user can pre-install multiple fixed detection devices on multiple fixed blocks of the same manufacturing process or production line according to the determined optimal positions of the multiple fixed blocks for pre-installing the fixed detection devices, so as to detect the assembly conditions of multiple fixed blocks of multiple manufacturing processes or production lines.

[0088] When the user determines the optimal positions of multiple fixed blocks for pre-installing fixed detection devices, the user needs to adjust the position of each fixed detection device on the fixed block multiple times, so that the first light-emitting hole 30 of each fixed detection device corresponds to the position of the second light-emitting hole 40 of the fixed detection device pre-installed on the previous fixed block in the assembly sequence, and the second light-emitting hole 40 corresponds to the position of the first light-emitting hole 30 of the fixed detection device pre-installed on the next fixed block in the assembly sequence. However, in the case where the relative positions between the first light-emitting holes 30 and the second light-emitting holes 40 of multiple fixed detection devices are fixed, the user needs to determine the optimal position of each fixed detection device on the fixed block through multiple adjustments, which not only has a large workload, but also takes a lot of time.

[0089] In this regard, in one embodiment of the present application, reference is made to Figure 8 In the case where the optical path structure 50 includes a first reflecting surface 51 and a second reflecting surface 52 provided on the substrate 20, the substrate 20 includes an upper substrate 21 and a lower substrate 22, the first light-emitting hole 30 and the first reflecting surface 51 are both located in the upper substrate 21, and the second light-emitting hole 40 and the second reflecting surface 52 are both located in the lower substrate 22; the fixed detection device includes a driving component 100, a first end of the driving component 100 is transmission-connected to the upper substrate 21, and a second end of the driving component 100 is transmission-connected to the lower substrate 22.

[0090] In this embodiment, the driving assembly 100 is used to connect and drive the upper half substrate 21 and the lower half substrate 22, so that the upper half substrate 21 and the lower half substrate 22 can move relative to each other according to actual needs, so as to adjust the relative position of the first light-emitting hole 30 and the second light-emitting hole 40. Optionally, the driving assembly 100 can be implemented by dual motor drive, wherein one motor is connected to the upper half substrate 21 and the other motor is connected to the lower half substrate 22, so as to independently control the relative positions of the upper half substrate 21 and the lower half substrate 22. Optionally, the driving assembly 100 can also be implemented by a single motor and a gear / connecting rod mechanism, for example, the driving assembly 100 includes a motor, a main gear, a first driven gear and a second driven gear, the motor is connected to the main gear through a coupling, the first driven gear is respectively meshed with the main gear and the gear of the upper half substrate 21, and the second driven gear is respectively meshed with the main gear and the gear of the lower half substrate 22.

[0091] Through the above settings, the user can adjust the relative positions of the first light-emitting hole 30 and the second light-emitting hole 40 through the driving assembly 100 according to actual needs. Fig. 9According to actual needs, the user rotates the upper substrate 21 or the lower substrate 22 of the fixed detection device B through the driving assembly 100 to adjust the relative positions of the first light-emitting hole 30 and the second light-emitting hole 40 from opposite sides to the same side, ensuring that the first light-emitting hole 30 of the fixed detection device B corresponds to the second light-emitting hole 40 of the fixed detection device A, and the second light-emitting hole 40 corresponds to the first light-emitting hole 30 of the fixed detection device C.

[0092] With such arrangement, in actual application, when the user determines the optimal position of multiple fixed blocks for pre-installing the fixed detection device, the fixed detection device can be determined not only by adjusting the position of the fixed detection device on the fixed block, but also by adjusting the relative position between the first light emitting hole 30 and the second light emitting hole 40 of the fixed detection device. The user can first roughly place the fixed detection device on the fixed block, and then adjust the relative position of the first light emitting hole 30 and the second light emitting hole 40 so that the first light emitting hole 30 and the second light emitting hole 40 are accurately aligned with the second light emitting hole 40 and the first light emitting hole 30 of the adjacent fixed detection device, thereby reducing the workload required for the user to adjust the position of the fixed detection device on the fixed block and improving the efficiency of determining the optimal position of the fixed detection device on the fixed block.

[0093] Furthermore, since the relative positions of the first light-emitting hole 30 and the second light-emitting hole 40 can be adjusted by the driving assembly 100, a more precise optical path alignment can be achieved, ensuring that light is transmitted from one fixed detection device to the next in a more ideal manner, thereby improving the accuracy of the fixed detection system of the present application in detecting the assembly status of multiple fixed blocks.
