[0022] In this application, the quality of the product includes the firmness of the coupling of a pair of buckling components when the box cover 12 is closed on the box body 11. If the coupling between the two is not firm, the product can be judged to be unqualified. Based on the above structure, the transmission frame 72, the push frame 73 and the box cover 12 form three movable links of the four-bar linkage. The first driving force is applied to the transmission frame 72 by the cover opening driver, and the push frame 73 transmits the force to the cover opening groove 1211 through the push head 731.

[0027] In the present application, the limit stop edge 212 is used to realize the positioning of the push frame 73 in the reset state. In the reset state, the push frame 73 is pressed against the limit stop edge 212 by the elastic force applied by the reset spring 74 to ensure that the push head 731 on the push frame 73 can be in the cover opening groove 1211. In this embodiment, the limit stop edge 212 is set on the horizontal plate 21.

[0028] In this embodiment, the return spring 74 is a tension spring, and the return spring 74 is connected between the push frame 73 and the fixing frame 2 .

[0029] In this embodiment, a suction nozzle 23 is further included. The suction nozzle 23 is arranged on the bottom surface of the limiting groove 210, and the suction nozzle 23 is connected to the vacuum generator through an air path.

[0030] In the present application, the suction nozzle 23 is used to apply a downward suction force to the box body 11 to prevent the box body 11 from being pushed out of the limiting groove 210 by an external force.

[0031] Example 2 Combination Figure 3 and 4 As shown, when the flip box is not assembled, the box body 11 and the box cover 12 are arranged horizontally, and the box body 11 and the box cover 12 are connected by a flow channel molding 13.

[0032] Based on the above structure, a buckle-type flip-lid box detection device in the present application further includes the following steps before the cover opening detector 7 is executed: S1, placing the injection molded product 1 on the fixing frame 2, and receiving the box body 11 in the limiting groove 210, wherein the limiting groove 210 is used to position the injection molded product 1; S2, the cutting device 3 is started to cut off the flow channel forming part 13; S3, the assembly device 4 is started, so that the box body 11 and the box cover 12 are rotatably connected; S4, the cover closing device 5 is started to close the box body 11 and the box cover 12.

[0033] Therefore, the injection molded product 1 can be automatically separated and assembled with a high degree of automation to improve production efficiency.

[0034] Combination Figure 7As shown, in this embodiment, the cutting device 3 includes an ultrasonic cutting table 31, on which a convex portion 311 corresponding to the flow channel forming part 13 is provided, and also includes a first driving component 32, which is used to drive the ultrasonic cutting table 31 to move in the vertical direction. In this application, the ultrasonic cutting table 31 is connected to an ultrasonic generator (not shown), and the convex portion 311 is the end execution end of the ultrasonic cutting table 31. When the first driving component 32 is driven to the convex portion 311 and the flow channel forming part 13 are attached, the ultrasonic generator is started, and the flow channel forming part 13 can be vibrated off from between the box body 11 and the box cover 12. Specifically, the flow channel forming part 13 is arranged in pairs, and the cutting device 3 is arranged below the flow channel forming part 13. A material stopper rod 312 is provided on the ultrasonic cutting table 31, and the top of the material stopper rod 312 is higher than the convex portion 311. When the convex portion 311 and the flow channel forming part 13 are attached, the material stopper rod 312 is arranged on the inner side of the flow channel forming part 13. The material blocking rod 312 is used to ensure that the flow channel forming part 13 falls outward, and prevents the flow channel forming part 13 from falling inward, which makes it difficult to discharge the material. In addition, the fixed frame 2 includes a horizontal plate 21, and the ultrasonic cutting table 31 is slidably connected with the horizontal plate 21 in the vertical direction. The horizontal plate 21 is provided with a slide groove adapted to the shape of the convex portion 311, and the bottom of the ultrasonic cutting table 31 is provided with a transmission convex portion 313. The first driving component 32 includes a first driving cylinder 321 and a transmission block 322. The transmission block 322 is installed on the movable component of the first driving cylinder 321, and the fixed component of the first driving cylinder 321 is installed at the bottom of the horizontal plate 21. The first driving cylinder 321 is used to drive the transmission block 322 to move horizontally. The transmission block 322 is provided with a lifting guide surface 3221 on the side near the transmission convex portion 313, and the transmission convex portion 313 abuts against the top of the lifting guide surface 3221. Based on the above structure, the longitudinal space is saved and the compactness is improved. Specifically, the lifting guide surface 3221 includes a high section and a low section arranged laterally, the high section is located above the low section, and an arc-shaped transition surface is provided between the high section and the low section. When the first driving cylinder 321 drives the transmission block 322 to move until the transmission convex portion 313 is in contact with the high section, the ultrasonic cutting table 31 rises until the convex portion 311 contacts the flow channel forming part 13, and when the first driving cylinder 321 drives the transmission block 322 to move until it is in contact with the low section, the convex portion 311 drops below the box cover 12 to make room for the box cover 12 to move laterally.

[0035] In this embodiment, the assembly device 4 includes a push plate 41 and a second drive assembly 42. The push plate 41 is arranged on the side of the box cover 12 away from the box body 11. The second drive assembly 42 is connected to the push plate 41 in a transmission manner to drive the push plate 41 to move horizontally. The fixed frame 2 is provided with a sliding groove 211 for accommodating the lateral movement of the box cover 12, and the box cover 12 is arranged in the sliding groove 211. The push plate 41 is driven to move by the second drive assembly 42 to push the box cover 12 to move toward the box body 11 until the rotating shaft buckle 141 and the rotating shaft 142 are coupled, and the sliding groove 211 is used to limit the box cover 12 from moving too far in the horizontal direction. Specifically, the sliding groove 211 is arranged on the fixed frame 2. A limit pressing plate 411 is extended from the upper end of the push plate 41, and the limit pressing plate 411 extends from the front end of the push plate 41 to limit the upward movement of the box cover 12. Before the cutting device 3 is started, the limiting pressure plate 411 moves to the top of the box cover 12. After the cutting device 3 is started, when the flow channel forming part 13 fits with the protrusion 311, the limiting pressure plate 411 provides a downward reaction force to ensure that the flow channel forming part 13 and the protrusion 311 are effectively fitted. After the cutting is completed, when the second driving component 42 drives the push plate 41 to push the box cover 12, the limiting pressure plate 411 is used to prevent the box cover 12 from moving too far upward. In this embodiment, the second driving component 42 includes a second driving cylinder 421, the cylinder body of the second driving cylinder 421 is installed on the push plate 41, and the telescopic rod of the second driving cylinder 421 is connected to the fixed frame 2.

[0036] In this embodiment, the lid closing device 5 includes a third driving assembly 52 and a swing frame 51 rotatably mounted on the fixed frame 2. The third driving assembly 52 is connected to the swing frame 51 in a transmission manner to drive the swing frame 51 to rotate on the fixed frame 2. A roller 511 is provided at the end of the swing frame 51. The roller 511 is extended along the width direction of the box cover 12. During the rotation of the swing frame 51, the roller 511 is used to push the box cover 12 to rotate on the box body 11. The swing frame 51 is driven to flip by the third driving assembly 52 to push the box cover 12 to rotate on the box body 11. During this process, the roller 511 contacts the box cover 12. In this embodiment, the swing frame 51 includes a pair of swing arms 512, the roller body 511 is rotatably mounted between the pair of swing arms 512, the swing arm 512 is rotatably mounted on the fixed frame 2, and a transmission gear 5121 is mounted on the swing arm 512 corresponding to the rotation axis of the swing arm 512; the third driving assembly 52 includes a third driving cylinder 521 and a rack frame 522, the rack frame 522 is connected to the movable assembly of the third driving cylinder 521, and a transmission rack 5221 is arranged on the rack frame 522, and the transmission rack 5221 is meshed with the transmission gear 5121. The rack frame 522 is driven to move by the third driving cylinder 521 to drive the transmission gear 5121 to rotate, so as to realize the rotation of the swing frame 51 to push a pair of buckling components to couple. When the pair of buckling components are coupled, the stroke of the third driving cylinder 521 can be limited, which has the advantage of simple control. In this embodiment, the rotating axis core of the swing frame 51 is not concentric with the rotating axis core of the box cover 12. Therefore, when the roller body 511 pushes the box cover 12 to flip, relative sliding occurs between the roller body 511 and the box cover 12. The roller body 511 is provided on the swing arm 512 for rotation to prevent the box cover 12 from being scratched during this process. Preferably, a flexible pad can be coated on the surface of the roller body 511. If the quality of the molded product is poor or the rotating shaft 142 breaks during the assembly process, the gap between the box body 11 and the box cover 12 will not be tight enough when a pair of snap-fitting components are coupled. Therefore, the tightness of the pressing between the box body 11 and the box cover 12 after the box cover 12 is covered on the box body 11 is an important indicator for detecting product quality.

[0037] Combination Figure 5 , Figure 6 and Figure 8The gap detection device 6 is also shown, and the gap detection device 6 includes a plug 61, a pulling driver 62 and a pressure sensor 68. A limit plate 22 is provided on one side of the box body 11, and the detection end of the pressure sensor 68 is arranged on the limit plate 22 near the box body 11. Before the lid closing device 5 is started, the plug 61 is arranged on the box body 11. After the lid closing device 5 is started, the plug 61 is clamped between the box body 11 and the box cover 12. The pulling driver 62 is connected to the plug 61 in a transmission manner, and the pulling driver 62 is used to pull the plug 61 from the box body 11 to the limit plate 22. Based on the above device, its principle is that after the lid closing device 5 is started, the plug 61 is clamped between the box body 11 and the box cover 12, and the plug 61 is pulled by the pulling driver 62. Due to the limit of the limit plate 22, the box body 11 will not move. The pressure generated by the box body 11 in this process is detected by the pressure sensor 68 to determine whether the box body 11 and the box cover 12 are tightly pressed. If the pressure detected by the pressure sensor 68 is greater than the preset value, it is judged that the box body 11 and the box cover 12 are tightly pressed together and the product is qualified. If the pressure detected by the pressure sensor 68 is less than the preset value, it is judged that the product is unqualified. In this embodiment, the thickness of the plug 61 is 0.2 mm. After the cover opening detector 7 completes the detection, the cover opening driver applies a preset second driving force to ensure that the box cover 12 is opened. At this time, the flip frame driving device 65 can drive the flip frame 63 to reset from the first posture to the second posture.

[0038] Specifically, the pulling driver 62 includes a pulling driving cylinder 621 and a sliding seat 622 connected to a movable component of the pulling driving cylinder 621, and the sliding seat 622 is connected to the plug 61. The pulling driving cylinder 621 drives the sliding seat 622 to move so as to drive the plug 61 to move.

[0039] In other embodiments, the gap detection device 6 further includes a flip frame 63, which is rotatably mounted on the fixed frame 2, and further includes a flip frame driving device 65, which is transmission-connected to the flip frame 63, and the plug 61 and the pulling driver 62 are mounted on the flip frame 63; The turning frame driving device 65 is used to drive the turning frame 63 to rotate, so that the turning frame 63 switches between the first posture and the second posture; In the first posture, the plug 61 is attached to the upper end of the box body 11; In the second posture, the plug 61 is located outside the box body 11. In the initial state, the flip frame 63 is in the second posture, and the box body 11 is placed in the limiting groove 210 to make room for placing the box body 11 in the limiting groove 210; When the box body 11 is placed in the limiting groove 210, the flip frame driving device 65 drives the flip frame 63 to rotate to the first posture, and the plug 61 presses on the upper end of the box body 11. The flip frame driving device 65 is a motor, and the flip frame 63 and the flip frame driving device 65 are connected through a sprocket-chain transmission.

[0040] Specifically, a limiting portion is provided on the fixed frame 2, and when the flip frame 63 is in the first posture, the flip frame 63 abuts against the limiting portion. The limiting portion is used to position the flip frame 63, and after the pulling driver 62 is started, the flip frame 63 is ensured to stop in the second posture. In this embodiment, the limiting portion is the upper end surface of the horizontal plate 21.

[0041] Specifically, a winding shaft 64 is rotatably provided on the flip frame 63, and the winding shaft 64 is arranged on the side of the box body 11 away from the limit plate 22. One end of the plug 61 is wound on the winding shaft 64, and the other end is connected to the pulling driver 62. A winding shaft driver 66 is installed on the flip frame 63, and the winding shaft driver 66 is connected to the winding shaft 64. In the present application, the winding shaft 64 has the effect of storing the plug 61 to a certain extent. After the plug 61 at the front end is used a certain number of times, it will be worn, affecting the detection accuracy. At this time, the plug 61 at the front section is cut off, and then the unworn plug 61 at the rear section is connected to the limit plate 22. In addition, before the pulling drive 62 is started, the winding shaft drive 66 locks the winding shaft 64 to prevent the winding shaft 64 from rotating; when the pulling drive 62 pulls the plug 61, the winding shaft drive 66 is in an unlocked state, and the winding shaft 64 rotates in the R direction as the plug 61 is pulled; when the plug 61 is reset, the winding shaft drive 66 drives the winding shaft 64 to rotate to pull the sliding seat 622 to reset, and the pulling drive cylinder 621 is in a disabled state during this process. In this embodiment, the winding shaft drive 66 is a stepping motor, and the winding shaft drive 66 and the winding shaft 64 are connected by a synchronous pulley-synchronous belt transmission. In other embodiments, a tension controller may be provided on the winding shaft 64 to prevent the winding shaft 64 from rotating too far when the plug 61 rotates. The specific tension controller may be a coil spring (not shown), which is provided between the winding shaft 64 and the flip frame 63 and is used to apply an elastic force opposite to the R direction to the winding shaft 64 to ensure synchronization when the winding shaft 64 is pulled and rotated.

[0042] Specifically, a positioning roller 67 is provided on the flip frame 63. When the flip frame 63 is in the first posture, the positioning roller 67 is arranged on the side of the box body 11 away from the limiting plate 22. The positioning roller 67 is pressed on the plug 61. The extension direction of the plug 61 between the positioning roller 67 and the sliding seat 622 is parallel to the upper end surface of the box body 11.

[0043] Specifically, the flip frame 63 includes a pair of side plates 631, a pair of connecting plates 632 are fixedly arranged between the side plates 631, the connecting plates 632 are extended along the sliding direction of the sliding seat 622, and a guide rail mounting surface is arranged on the connecting plate 632. The pair of guide rail mounting surfaces are perpendicular to each other, and a guide rail 6321 is mounted on the guide rail mounting surface, and the sliding seat 622 is slidably mounted on the guide rail 6321. That is, the pair of vertically arranged connecting plates 632 are slidably connected to the sliding seat 622 to ensure the stability of the connection between the sliding seat 622 and the flip frame 63 during the flipping and switching process of the flip frame 63. Specifically, when the flip frame 63 is in the first posture, one of the connecting plates 632 is below the sliding seat 622.
