[0044] Some embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0045] See also Figure 1 The embodiment of the present application provides a detection device 100, which includes a positioning component 10, a frame 20, a pushing component 30 and an imaging component 40. The detection device 100 is used to detect a product 200. Figure 2 , wherein the product 200 includes a first workpiece 201 and a second workpiece 202 connected to each other. The first workpiece 201 can be a mobile phone frame, and the second workpiece 202 can be a mobile phone mid-plate. The first workpiece 201 and the second workpiece 202 can be welded or adhesively connected.

[0046] See also Figure 1 and Figure 2The positioning assembly 10 is used to position the first workpiece 201, and the frame 20 is mounted on the positioning assembly 10. The pushing assembly 30 includes a pushing drive member 31 and a pushing member 32. The pushing drive member 31 is arranged on the frame 20 and connected to the pushing member 32. The pushing drive member 31 is used to drive the pushing member 32 to push the second workpiece 202. The imaging assembly 40 includes an imaging member 41. The imaging member 41 is arranged on the frame 20 with an interval between the imaging member 41 and the pushing drive member 31. The imaging member 41 is used to capture an image of the connection between the second workpiece 202 and the first workpiece 201 after pushing, so as to detect the product 200. The processor 44 is communicatively connected to the pushing drive member 31, that is, electrically connected to the pushing drive member 31, for controlling the pushing operation of the pushing drive member 31. The processor 44 is communicatively connected to the imaging member 41, that is, electrically connected to the imaging member 41, for controlling the imaging member 41 to perform relevant functional operations, such as detecting the product 200 based on the image information of the imaging member 41. Exemplarily, the image capturing element 41 may be an industrial camera; the processor 44 may be a chip circuit having control and communication functions, such as a PLC controller and a single-chip microcomputer.

[0047] When the above-mentioned detection device 100 is actually used, the first workpiece 201 is positioned by the positioning component 10, and the pushing member 31 drives the pushing member 32 to apply a preset thrust to the second workpiece 202, so that the imaging member 41 captures the image of the connection between the second workpiece 202 and the first workpiece 201 after the push. The processor 44 intuitively detects whether the gap value between the first workpiece 201 and the second workpiece 202 exceeds the preset gap standard based on the image, and then accurately determines whether the product 200 is qualified, thereby improving the detection accuracy of the product 200.

[0048] See also Figure 1 and Figure 3 In some embodiments, the imaging assembly 40 further includes a reflector 42, a light emitting element 43, and a processor 44. The reflector 42 is connected to the frame 20. The light emitting element 43 is disposed on a side of the frame 20 facing the positioning assembly 10 and is connected to the frame 20. The light emitting element 43 is configured to emit light toward the second workpiece 202. The light is reflected by the second workpiece 202 and the reflector 42 to the imaging element 41.

[0049] Since the second workpiece 202 is connected to the inner cavity wall of the first workpiece 201, the imaging element 41 cannot directly capture the image of the connection between the first workpiece 201 and the second workpiece 202. Therefore, by setting the above-mentioned emitting element and the light-emitting element 43, the light emitted by the light-emitting element 43 is reflected to the imaging element 41 through the second workpiece 202 and the emitting element, ensuring that the imaging element 41 stably obtains the image of the connection between the first workpiece 201 and the second workpiece 202.

[0050] See also Figure 1 and Figure 4In some embodiments, the frame 20 includes a base 21, a support frame 22, and a guide member 23. The base 21 is mounted on the positioning assembly 10 and has a through-hole 211. The imaging element 41 is disposed around the through-hole 211 and captures an image of the connection between the first workpiece 201 and the second workpiece 202 through the through-hole 211. The support frame 22 is disposed on the side of the base 21 facing away from the positioning assembly 10 and is connected to the driving member 31. The guide member 23 is disposed through the base 21 and sleeved on the driving member 32. The guide member 23 is used to guide the driving member 32.

[0051] Thus, by providing the base 21 and the support frame, respectively connecting the image capturing element 41 and the driving element 31, the frame 20, the image capturing assembly 40, and the driving element 30 are rationally arranged. Furthermore, by providing a through hole 211 in the base 21, the image capturing element 41 is positioned at the junction of the first workpiece 201 and the second workpiece 202 through the through hole 211, preventing the base 21 from obstructing the image capturing element 41 and ensuring stable image capture by the image capturing element 41. Furthermore, by fitting the guide member 23 onto the driving element 32, the guide member 23 guides the movement direction of the driving element 32, allowing the driving element 32 to accurately push the second workpiece 202 to a predetermined position, thereby ensuring the inspection accuracy of the product 200.

[0052] See also Figure 1 、 Figure 3 and Figure 4 In some embodiments, the reflector 42 includes a lifting drive body 421, a support body 422, and a reflector 423. The lifting drive body 421 is arranged around the through hole 211 and connected to the base 21. The lifting drive body 421 is electrically connected to the processor 44. The support body 422 is movably arranged in the through hole 211 and connected to the lifting drive body 421. The reflector 423 is tilted relative to the support body 422 and is detachably connected to the support body 422. The reflector 423 is used to adjust to a preset height under the drive of the lifting drive body 421 to reflect light to the imaging element 41. Exemplarily, the lifting drive body 421 can be a cylinder, and the reflector 423 can be any reflective part, reflective sheet, or similar reflective block that can reflect light.

[0053] In this way, the processor 44 controls the lifting drive 421 to drive the support 422 to drive the reflector 423 to move synchronously, thereby adjusting the reflector 423 to a preset height, ensuring that the reflector 423 accurately reflects light to the imaging element 41. After the product 200 is inspected, the lifting drive 421 drives the support 422 to move the reflector 423 away from the positioning assembly 10, making it easier for the operator to remove the inspected product 200 and avoiding interference between the product 200 and the reflector 42. In addition, by providing a detachable connection between the reflector 423 and the support 422, the operator can easily adjust the inclination angle of the reflector 423 to ensure that the reflector 423 stably reflects light to the imaging element 41.

[0054] See also Figure 1 In some embodiments, the number of push assemblies 30 and imaging assemblies 40 is multiple, and the multiple push assemblies 30 are spaced apart and arranged on the frame 20. The multiple imaging assemblies 40 correspond to the multiple push assemblies 30 and are respectively connected to the frame 20. It is understood that the multiple groups mentioned above refer to two or more groups.

[0055] In this way, by setting up multiple groups of pushing components 30 and multiple groups of imaging components 40 in one-to-one correspondence, multiple groups of pushing components 30 respectively push different positions of the second workpiece 202, so that multiple groups of imaging components 40 respectively take images of the connection points between the second workpiece 202 and the first workpiece 201 at different positions, and then detect different positions of the product 200, ensuring that the product 200 is completely detected.

[0056] See also Figure 1 and Figure 3 There are multiple reflectors 423, and the number of the multiple reflectors 423 is consistent with the number of the pushing components 30. The support body 422 includes a support frame 4221 and multiple support parts 4222. The support frame 4221 is movably inserted into the through hole 211 and connected to the lifting drive body 421. The multiple support parts 4222 correspond one-to-one to the multiple reflectors 423 and are respectively connected to the support frame 4221.

[0057] Thus, by configuring the specific structure of the support body 422, the support frame 4221 drives the multiple reflectors 423 to move synchronously through the multiple support portions 4222. This allows the multiple reflectors 423 to move synchronously through a single drive source, the elevating drive body 421. This simplifies the mechanical structure of the reflector 42 and facilitates the rational layout of the detection device 100. The support frame 4221 is a frame structure, so the imaging element 41 can receive light reflected by the reflectors 423 through the support frame 4221 to capture images.

[0058] See also Figure 1 and Figure 3 In some embodiments, the light-emitting element 43 includes a connector 431, a light-emitting element 432, and a locking element 433. The connector 431 is disposed on a side of the frame 20 facing the positioning assembly 10 and is connected to the frame 20. The connector 431 defines an adjustment hole 4311. The light-emitting element 432 is rotatably connected to the connector 431 and is configured to emit light. The locking element 433 is disposed through the adjustment hole 4311 and is detachably connected to the light-emitting element 432, and is configured to lock and secure the light-emitting element 432. For example, the light-emitting element 432 may be a bar-shaped light source, and the locking element 433 may be a bolt.

[0059] In this way, by setting the specific structure of the above-mentioned light-emitting component 43, the operator can adjust the inclination angle of the light-emitting body 432 so that the locking body 433 passed through the adjustment hole 4311 is connected to the adjusted light-emitting body 432, thereby fixing the adjusted light-emitting body 432, and then ensuring that the light emitted by the light-emitting body 432 is stably reflected through the second workpiece 202 and the reflector 423 to the imaging component 41.

[0060] See also Figure 1 and Figure 5 In some embodiments, the pushing driving member 31 includes a pushing driving body 311, a linkage body 312 and a sensor 313. The pushing driving body 311 is arranged on the frame 20 and connected to the linkage body 312. The linkage body 312 is provided with a seating groove 3121 and a connecting hole 3122. The connecting hole 3122 is opened at the bottom of the seating groove 3121 adjacent to the positioning component 10 and is connected to the seating groove 3121. The sensor 313 is embedded in the other bottom of the seating groove 3121 and corresponds to the connecting hole 3122. The pusher 32 includes a pusher 321 and an elastic body 322. The pusher 321 is movably arranged in the connecting hole 3122 and extends to the placement groove 3121. The pusher 321 abuts the bottom of the placement groove 3121. The pusher 321 is used to move closer to the positioning assembly 10 under the drive of the linkage body 312. The elastic body 322 is provided at one end of the pusher 321 facing the sensor 313 and is connected to the pusher 321. The elastic body 322 is used to move relative to the linkage body 312 and abut against the sensor 313 under the drive of the pusher 321. Among them, the processor 44 is electrically connected to the pusher driving body 311 and the sensor 313 respectively. For example, the pusher driving body 311 can be a cylinder, the sensor 313 can be a pressure sensor 313, and the elastic body 322 can be a spring.

[0061] In this way, the processor 44 controls the pushing driving body 311 to drive the linkage body 312 to drive the pushing body 321 to move close to the second workpiece 202. After the pushing body 321 abuts against the second workpiece 202, the elastic body 322 moves relative to the linkage body 312 and abuts against the sensor 313 under the drive of the pushing body 321. The processor 44 receives the pressure sensing signal sent by the sensor 313, and then controls the processor 44 to make the pushing driving body 311 compress the elastic body 322 to the pushing body 321 through the sensor 313, so that the pushing body 321 flexibly presses the second workpiece 202 to avoid damage to the second workpiece 202. At the same time, the sensor 313 can sense the thrust applied to the second workpiece 202 by the pushing body 321 to ensure that the thrust applied to the second workpiece 202 by the pushing member 322 is the preset thrust, so that the detection device 100 can stably detect the product 200.

[0062] See also Figure 5In some embodiments, the pushing body 321 includes a connecting portion 3211 and a pushing portion 3212. The connecting portion 3211 is movably arranged in the connecting hole 3122 and abuts against the bottom of the seating groove 3121. The opposite ends of the connecting portion 3211 are respectively connected to the elastic body 322 and the pushing portion 3212. The cross-sectional area of ​​the connecting portion 3211 is larger than the cross-sectional area of ​​the pushing portion 3212.

[0063] In this way, by setting the cross-sectional area of ​​the connecting portion 3211 to be larger than the cross-sectional area of ​​the pushing portion 3212, the pushing body 321 can utilize the large structural size of the connecting portion 3211 to enhance the structural strength of the pushing body 321 and prevent the pushing body 321 from being damaged during use. The small structural size of the pushing portion 3212 can be utilized to facilitate the flexible use of the pushing portion 3212 and avoid collisions between the pushing body 321 and other components when pushing the second workpiece 202 to the preset position.

[0064] Please continue reading Figure 5 In some embodiments, a supporting groove 3211a is formed on the side wall of the connecting portion 3211, and the supporting groove 3211a is adjacent to the elastic body 322 relative to the pushing portion 3212. The two opposite groove walls of the supporting groove 3211a are located on both sides of the connecting hole 3122, and the groove wall of the supporting groove 3211a adjacent to the elastic body 322 is used to abut against the groove bottom of the placement groove 3121.

[0065] In this way, by opening a supporting groove 3211a on the side wall of the connecting portion 3211, when the pushing body 321 is in the initial position, the groove wall of the supporting groove 3211a adjacent to the elastic body 322 abuts against the groove bottom of the receiving groove 3121, so that the linkage body 312 supports the connecting portion 3211 to drive the pushing portion 3212 to move closer to the second workpiece 202, thereby ensuring the linkage operation of the linkage body 312 and the pushing body 321.

[0066] See also Figure 5 In some embodiments, the side wall of the linkage body 312 is provided with an opening 3123 , and the opening 3123 is communicated with the seating groove 3121 .

[0067] Thus, by providing the opening 3123 on the side wall of the linkage body 312 , it is convenient to assemble the pushing member 32 into the receiving groove 3121 of the linkage body 312 through the opening 3123 , which is beneficial to the reasonable layout of the driving member 31 and the pushing member 32 .

[0068] See also Figure 1In some embodiments, the positioning assembly 10 includes a conveyor 11, a carrier 12, and a positioning member 13. The conveyor 11 is disposed below the frame 20. The carrier 12 is connected to the conveyor 11 and is used to carry the first workpiece 201. The positioning member 13 is connected to the carrier 12 and is used to position the first workpiece 201 carried by the carrier 12. For example, the conveyor 11 can be a servo slide.

[0069] Thus, when inspecting product 200, carrier 12 is conveyed to the bottom of pusher 32 by conveyor 11, so that pusher 32 can stably push against second workpiece 202. After product 200 is inspected, carrier 12 is moved away by conveyor 11, making it easier for the operator to remove the inspected product 200, thus facilitating repeated operations of inspection device 100. Furthermore, positioning member 13 positions first workpiece 201 carried by carrier 12, ensuring that first workpiece 201 and second workpiece 202 connected to first workpiece 201 maintain a preset orientation and placement, facilitating pusher 32 to accurately push against the preset position of second workpiece 202, while ensuring that imaging element 41 accurately captures an image of the connection between first workpiece 201 and second workpiece 202.

[0070] Please continue reading Figure 1 In some embodiments, the positioning assembly 10 further includes a pressing member 14, which includes a pressing driving body 141 and a pressing body 142. The pressing driving body 141 is spaced apart from the positioning member 13 and is disposed on the supporting member 12. The pressing body 142 is connected to the pressing driving body 141. For example, the pressing driving body 141 can be a rotary telescopic cylinder.

[0071] In this way, by setting the above-mentioned pressing member 14, the pressing driving body 141 drives the pressing body 142 to press the first workpiece 201 to the supporting member 12, ensuring that the first workpiece 201 remains in a stable position during the detection process, avoiding the first workpiece 201 from shaking during the detection and affecting the detection results.

[0072] The working process of the above-mentioned detection device 100 is roughly as follows:

[0073] First, the carrier 12 receives the product 200 and carries the first workpiece 201. The positioning member 13 positions the first workpiece 201 on the carrier 12. The pressing member 14 presses the first workpiece 201 onto the carrier 12. The conveying member 11 drives the carrier 12 to move the first workpiece 201 and the second workpiece 202 to the bottom of the pushing member 32.

[0074] Then, the driving body 311 drives the linkage body 312 to drive the pushing body 321 to move closer to the second workpiece 202. After the pushing body 321 abuts the second workpiece 202, the elastic body 322 moves relative to the linkage body 312 under the drive of the pushing body 321 and abuts the sensor 313. The driving body 311 compresses the elastic body 322 toward the pushing body 321 through the sensor 313, so that the pushing body 321 flexibly presses against the second workpiece 202 and applies a preset thrust to the second workpiece 202. At the same time, the sensor 313 can sense the magnitude of the thrust applied by the pushing body 321 to the second workpiece 202.

[0075] Finally, the light emitted by the light-emitting element 43 is reflected by the second workpiece 202 and the emitting element to the imaging element 41. The imaging element 41 obtains the image of the connection between the first workpiece 201 and the second workpiece 202.
