During the assembly process of the button assembly and other components, it is necessary to confirm whether the button is the target model and whether the spring is detached from the button to achieve the accurate assembly of the button assembly and ensure the stability of unlocking. In the related art, manual inspection of the button and the spring may result in misjudgment, causing the button model of the button assembly to be judged correctly only during subsequent assembly, so that the button assembly needs to be reworked and reinstalled, that is, the detection accuracy of manual inspection is low, affecting the automated assembly production of the button assembly.

[0057] In view of this, an embodiment of the first aspect of the present application provides a detection device 10 for detecting a button assembly 20.

By sensing and detecting the model of the button assembly 20 through the first sensor 310, the sensing assembly 300 can prevent assembly mixing and ensure the accuracy of the assembly of the button assembly 20. It should be noted that the first sensor 310 can sense the button part 21 of the button assembly 20.

[0060] Refer to Figure 4 and Figure 10 , the second sensor 320 is used to sense the spring part 22 of the button assembly 20 to detect and confirm whether the spring part 22 of the button assembly 20 is separated from the button part 21. The specific sensing position of the second sensor 320 can be determined according to the actual situation. Through the sensing and detection operation of the second sensor 320, the sensing assembly 300 can prevent the button assembly 20 lacking the spring part 22 from being assembled and improve the accuracy of the overall assembly operation.

[0061] Refer toFigures 6 to 9 The position switching component 200 is used to switch the orientation of the button component 20. Specifically, the position switching component 200 can be connected to the transmission part 120, that is, it can obtain the button component 20 output by the transmission part 120. The first sensor 310 of the sensing component 300 can detect and confirm the model of the button component 20 output by the transmission part 120.

The feeding component 100 includes a storage part 110 and a transmission part 120. In the prior art, the model and spring of the button component are detected manually, and the detection accuracy is relatively low. In this solution, the button component 20 is stored in the storage part 110, and the button component 20 stored in the storage part 110 is transmitted through the transmission part 120. The first sensor 310 can sense the model of the button component 20, and the second sensor 320 can sense the spring part 22.

Therefore, the position switching component 200 of this solution can switch the orientation of the button component 20 to meet the orientation detection requirements of different sensors, further improve the detection accuracy, and optimize the structural layout of the detection device 10.

[0064] Refer to Figure 1 Next, the specific settings of the detection device 10 will be introduced. First, the storage box 111 will be introduced.

Specifically, the storage box 111 defines a cavity that can accommodate the button component 20, and the specific size and structure of the cavity can be determined according to the actual situation.

[0065] Refer to Figure 1 and Figure 2, the specific settings of the transmission unit 120 will be introduced below. In some embodiments, the transmission unit 120 includes a vibrator and a transfer guide rail 121, and the vibrator is connected to the transfer guide rail 121. The vibrator generates vibrations through an electric device or a pneumatic device, and the above vibrations can be transmitted to the button assembly 20 through the transfer guide rail 121, so that the button assembly 20 can be affected by the vibrations and move along the transfer guide rail 121. Specifically, one end of the transfer guide rail 121 can extend into the cavity, that is, the button assembly 20 in the cavity can be acquired by the transfer guide rail 121 and conveyed. The other end of the transfer guide rail 121 can cooperate with the position switching component 200, that is, the button assembly 20 can be conveyed to the position switching component 200 for position switching to perform the commutation operation of the button assembly 20.

[0066] In some other embodiments, the transmission unit 120 can include a conveyor belt and a motor, and the motor can drive the conveyor belt to move to realize the conveyance of the button assembly 20. In other embodiments, the transmission unit 120 can include a slider, a slide rail and a motor, and the motor can drive the slider to slide relative to the slide rail, and the slider can carry the button assembly 20 to realize the conveyance. The specific settings of the transmission unit 120 can be determined according to the actual situation. Some embodiments of the present application are described by taking the transmission unit 120 including a vibrator and a transfer guide rail 121 as an example. The vibration frequency of the vibrator and the angle setting of the transfer guide rail 121 can be determined according to the actual situation.

[0067] The storage bin 111 of this solution can realize the storage operation of the button assembly 20. The vibrator and the transfer guide rail 121 of the transmission unit 120 can smoothly convey the button assembly 20 from the storage bin 111 to the position switching component 200 for orientation switching, which can ensure the detection accuracy and assembly stability of the button assembly 20.

[0068] Refer to Figure 6 and Figure 7 , the specific settings of the transfer guide rail 121 in some embodiments will be introduced below. The transfer guide rail 121 includes a first track and a second track. In some embodiments, the structures of the first track and the second track can be set in the same way. In some other embodiments, the structures of the first track and the second track can be set differently. The specific settings of the first track and the second track can be determined according to the actual situation. Some embodiments of the present application are described by taking the structures of the first track and the second track as the same as an example.

[0069] Refer to Figure 5, the button part 21 includes a guide rod 24 and a button cap 23, and the button cap 23 is connected to one end of the guide rod 24 along its extending direction. The button cap 23 and the guide rod 24 can be integrally connected and arranged. Further, the button part 21 can include two guide rods 24, and the two guide rods 24 can be spaced apart from each other. A connecting column can be provided between the two guide rods 24, and the spring part 22 can be sleeved on the outer periphery of the connecting column. The specific structure and connection arrangement of the button part 21 and the spring part 22 can be determined according to the actual situation.

[0070] Referring to Figure 6 , the first track and the second track of the transfer guide rail 121 can be arranged at intervals, and the gap between the first track and the second track can accommodate the guide rod 24 of the button part 21. Moreover, the first track and the second track can jointly support the button part 21. Specifically, the first track and the second track can support the two lateral sides of the lower end wall of the button cap 23. It should be noted that in some embodiments, the detection device 10 can include a single transfer guide rail 121. In other embodiments, the detection device 10 can include multiple transfer guide rails 121. Some embodiments of the present application will be described by taking the detection device 10 including a single transfer guide rail 121 as an example.

[0071] The first track and the second track of this solution can stably support the button part 21, prevent the button part 21 from shifting, enable the button part 21 to move smoothly along the transfer guide rail 121, avoid the guide rod 24 from being stuck and causing stagnation, and ensure the smoothness of the transportation of the button assembly 20 and the stability of the detection.

[0072] The following introduces the specific setting of the first sensor 310 in some embodiments. Referring to Figure 6 In terms of orientation, the first sensor 310 can be arranged above the transmission part 120, and the first sensor 310 can sense the model of the button assembly 20 downward from above the button assembly 20. In the related art, the first sensor senses the button assembly laterally, and due to the influence of the surrounding environment of the button assembly, the edge gradient of the button assembly is not obvious, so the accuracy of the first sensor sensing the model of the button assembly is poor, resulting in a low detection accuracy. The first sensor 310 of this solution senses the button assembly 20 vertically, can effectively reduce the interference of the external environment on the first sensor 310, ensure the accuracy of sensing, and improve the sensing accuracy.

[0073] The following describes the specific indication of the model of the button component 20. In some embodiments, the model of the button component 20 may be the color of the button portion 21. In some other embodiments, the model of the button component 20 may be the size of the button portion 21. In other embodiments, the model of the button component 20 may be the shape or material of the button portion 21, etc. In some embodiments of the present application, the model of the button component 20 being the color of the button portion 21 is taken as an example for illustration. That is, the first sensor 310 can sense at least one of the color, size, shape, or material of the button portion 21. This solution can adapt to various detection requirements, improve the accuracy of assembling the button component 20, and ensure the quality of the finished product.

[0074] Refer to Figure 1 , Figure 2 , Figures 6 to 9 , the following describes the specific settings of the position switching component 200 in some embodiments. The position switching component 200 includes a moving portion 210 and a rotating portion 220. The moving portion 210 is used to move the button component 20, and the rotating portion 220 is used to rotate the button component 20. Specifically, the moving portion 210 can be connected to the transmission portion 120 of the feeding component 100. The moving portion 210 can obtain the button component 20 output by the transmission portion 120 at the first position and translate the button component 20 to the second position. It can be understood that the first position and the second position are spaced apart in the horizontal direction. The rotating portion 220 is used to rotate the button component 20 located at the second position around the transverse axis. The specific rotation angle and rotation direction of the button component 20 can be determined according to the actual situation. The moving portion 210 of this solution can adjust the position of the button component 20, and the rotating portion 220 can adjust the arrangement direction of the button component 20, so that the button component 20 can meet the sensing requirements of relevant sensors, ensuring the detection accuracy and the stability of detection.

[0075] Refer to Figure 6, the specific structure of the moving part 210 of some embodiments is introduced below. The moving part 210 includes a first driving cylinder 211, a base plate 212 and a limit frame 213. The limit frame 213 can accommodate the button assembly 20. Specifically, the limit frame 213 includes a limit cavity and an opening connected to the limit cavity. When the moving part 210 is in the first position, the opening of the limit cavity faces the transmission part 120, so that the opening can obtain the button assembly 20 output by the transmission part 120, that is, the button assembly 20 can enter the limit frame 213 through the opening. The limit frame 213 can be connected to the base plate 212, and further, the limit frame 213 can be bolted or integrally connected to the base plate 212. The first driving cylinder 211 can be connected to the base plate 212 and can drive the base plate 212 to translate horizontally, so that the button assembly 20 can be moved to the second position. The moving part 210 of the present solution can transport the button assembly 20 to a specified position through the first driving cylinder 211 , and position and limit the button assembly 20 through the limit frame 213 , thereby ensuring the accuracy and stability of sensing the button assembly 20 .

[0076] Reference Figure 6 In some embodiments, the top plate of the limit frame 213 may be provided with a first through hole 2132, the first through hole 2132 may extend in the up-down direction and communicate with the limit cavity, and the specific size and shape of the first through hole 2132 may depend on the actual situation. The first sensor 310 may be provided on the upper side of the limit frame 213. It can be understood that the button assembly 20 may be arranged along the vertical extension in the limit frame 213, and the first sensor 310 may sense the color of the button cap 23 of the button assembly 20 through the first through hole 2132. This solution can effectively reduce the interference of the external environment on the first sensor 310, further improve the accuracy of sensing, and improve the assembly accuracy.

[0077] Reference Figures 6 to 9 The specific structure of the rotating part 220 of some embodiments is described below. The rotating part 220 includes a second driving cylinder 221 and a push rod 222. The second driving cylinder 221 can have the same structure as the first driving cylinder 211, or it can be different. The side plate of the limiting frame 213 facing away from the opening can be provided with a second through hole 2133, refer to Figure 6 The second driving cylinder 221 can drive the push rod 222 to translate in the lateral direction and extend into the limit frame 213 from the second through hole 2133. The push rod 222 extending into the limit frame 213 can push the button part 21 to flip, and enable the button assembly 20 to move out of the limit frame 213 from the opening, so as to facilitate subsequent sensing operations. Figure 10 The push rod 222 can push the button portion 21 to flip until the two guide rods 24 are respectively located on the upper and lower sides of the spring portion 22, so that the second sensor 320 can sense the spring portion 22 along the horizontal direction.

[0078] The second driving cylinder 221 of this solution can drive the push rod 222 to enter the limiting frame 213 through the second through hole 2133 to drive the button part 21 to flip, enabling the button assembly 20 to reliably rotate to the target position and ensuring the accuracy and stability of the position switching of the button assembly 20.

Refer to Figure 9 As shown in [relevant figure], the detection device 10 further includes a positioning part 500, and the positioning part 500 is used to position the button assembly 20. Specifically, the positioning part 500 can position the button assembly 20 pushed out of the limiting frame 213 by the push rod 222, ensuring the accuracy of subsequent detection.

[0081] Refer to Figure 10 As shown in [relevant figure], the specific setting of the second sensor 320 is introduced below. In some embodiments, the second sensor 320 can be set at the end of the first clamping arm 421. In other embodiments, the second sensor 320 can be set at the end of the second clamping arm 422.

The positioning part 500 can position the button assembly 20 so that the button assembly 20 can be accurately transferred to the sensing position. The second sensor 320 can reliably sense whether the spring part 22 is separated from the button part 21, ensuring the stability and accuracy of sensing.

[0083] A second aspect embodiment of the present application provides an assembly system for assembling a child seat, where the child seat includes a button assembly 20. The assembly system includes the detection device 10 of the above embodiment. It can be understood that the assembly system may include a robotic arm or a vision detection system, etc. The robotic arm can assemble the qualified button assembly 20 to the target position of the seat part. The vision detection system can monitor in real time during the assembly process to ensure the accuracy of each assembly link. In addition, the assembly system can also be connected to the management system of the production line to realize real-time transmission and analysis of production data.

[0084] In this solution, the button assembly 20 is stored in the storage part 110, and the button assembly 20 stored in the storage part 110 is transmitted through the transmission part 120. Moreover, the first sensor 310 can sense the model of the button assembly 20, and the second sensor 320 can sense the spring part 22. That is, this solution can effectively improve the detection accuracy of the button assembly 20, ensure the detection efficiency, and greatly reduce the misjudgment situation. The position switching component 200 can switch the orientation of the button assembly 20 to meet the orientation detection requirements of different sensors, further improve the detection accuracy, and optimize the structural layout of the detection device 10.

[0085] The specific action process of the assembly system of an embodiment is introduced below. First, the button assembly 20 is placed in the cavity of the storage box 111. The vibrator of the transmission part 120 drives the button assembly 20 to move along the transmission guide rail 121. The first track and the second track of the transmission guide rail 121 can jointly support the button cap 23 of the button part 21. The first driving cylinder 211 of the moving part 210 in the position switching assembly 200 can drive the limit frame 213 to move to the first position, and the opening can obtain the button assembly 20 at the first position, that is, the button assembly 20 can enter its cavity through the opening of the limit frame 213. The first sensor 310 can be arranged above the limit frame 213, and can sense the model of the button assembly 20 through the first perforation 2132. When the model of the button assembly 20 does not match the target model, the button assembly 20 will be marked as NG and discharged from the assembly line; when the model of the button assembly 20 matches the target model, the second driving cylinder 221 of the rotating part 220 can drive the push rod 222 to translate horizontally and extend from the second through hole 2133 into the limiting hole. The push rod 222 can push the button part 21 to flip, and rotate the button part 21 until the two guide rods 24 are respectively located on the upper and lower sides of the spring part 22. The driving bracket 410 of the transfer assembly 400 can drive the transfer clamp 420 to translate horizontally or vertically. The first clamping arm 421 and the second clamping arm 422 of the transfer clamp 420 can move relative to each other horizontally to clamp the guide rod 24 of the button part 21. The positioning part 500 can position the button assembly 20. The second sensor 320 on the first clamping arm 421 or the second clamping arm 422 can sense the spring portion 22 between the two guide rods 24 to confirm whether the spring portion 22 is separated from the button portion 21. When the second sensor 320 does not detect the spring portion 22, the button assembly 20 will be marked as NG, and the part of the button assembly 20 will be moved to the NG slot and thrown in. When the second sensor 320 senses the spring portion 22, the button assembly 20 will be transferred to the subsequent assembly station for assembly with other parts. The assembly system of this solution can improve assembly efficiency and ensure assembly accuracy.
