Description

Technical Field

[0001] This invention relates to the field of flip-top box quality inspection, and specifically to a snap-on flip-top box inspection device. Background Technology

[0002] Hook-and-loop flip boxes use a locking mechanism to couple the box body to the lid, offering the advantage of locking when the lid is closed. They are convenient to use and widely applicable. The tightness of the locking mechanism is a crucial indicator for hook-and-loop flip boxes. Poor tightness can cause the box to open when flipped, affecting usability. Therefore, there is an urgent need to design a testing device to ensure the secure connection of the locking mechanism in hook-and-loop flip boxes. Summary of the Invention

[0003] To overcome the shortcomings of the prior art, the present invention provides a snap-on flip box detection device, which can automatically detect the reliability of the coupling of the flip box fastening components.

[0004] To achieve the above objectives, the present invention is implemented through the following technical solution:

[0005] A snap-on flip box detection device is used to detect the quality of the flip box. The flip box includes a box body and a box lid that are rotatably connected to each other. The box body and the box lid are provided with a pair of corresponding snap-on components. The box lid is provided with an opening groove.

[0006] Also includes:

[0007] The mounting bracket has a limiting groove at the bottom of the storage box.

[0008] It also includes a lid opening detector, which includes a lid opening driver, a transmission frame and a pusher. The transmission frame is rotatably mounted on a fixed frame and is rotatably connected to the pusher. The end of the pusher away from the transmission frame is provided with a push head that is adapted to the lid opening groove. When the lid and the box body are closed, the push head abuts against the inside of the lid opening groove. The lid opening driver is rotatably connected to the transmission frame and is used to apply a preset driving force to the transmission frame.

[0009] Furthermore, in the snap-on flip-top box detection device of this application, the push head is cylindrical with its axis parallel to the opening groove, and the push head is rotatably mounted at the end of the push frame.

[0010] Furthermore, in the latch-type flip-top box detection device of this application, the opening actuator is a cylinder. A pair of relatively telescopic components of the cylinder are rotatably connected to a fixed frame and a transmission frame, respectively. The cylinder is mounted on the fixed frame on the side of the box body away from the lid. As a preferred embodiment of this application, the stability of the driving force generated by the opening actuator can be ensured by controlling the driving air pressure of the cylinder.

[0011] Furthermore, the snap-on flip box detection device of this application also includes a return spring, which is elastically connected to the push frame, and a limiting stop is provided on the fixing frame;

[0012] When the cover opening driver is not activated, the reset spring presses the pusher against the limiting flange. As a preferred embodiment of this application, the limiting flange is used to position the pusher in the reset state. In the reset state, the pusher is pressed against the limiting flange by the elastic force applied by the reset spring to ensure that the push head on the pusher can be in the cover opening groove.

[0013] Furthermore, in the snap-on flip box detection device of this application, the reset spring is a tension spring, which is connected between the push frame and the fixed frame.

[0014] Furthermore, the snap-on flip-top box detection device of this application also includes a suction nozzle, which is disposed on the bottom surface of the limiting groove and is connected to a vacuum generator via an air passage. As a preferred embodiment of this application, the suction nozzle is used to apply a downward suction force to the box body to prevent the box body from being pushed out of the limiting groove by external force.

[0015] Furthermore, in this application, a snap-on flip box detection device is provided. When the flip box is not assembled, the box body and the box cover are arranged horizontally. The box body and the box cover are connected by a flow channel forming part. Each of the box body and the box cover is provided with a rotating connecting part. The rotating connecting part includes a rotating shaft snap and a rotating shaft respectively provided on a pair of rotating connecting bodies on the same side. The pair of rotating connecting bodies are the box body and the box cover.

[0016] The cutting device is used to cut off the flow channel formed parts;

[0017] An assembly device for moving the lid to a hinge and coupling the hinge;

[0018] A lid-closing device for flipping the lid so that it couples with a pair of locking components.

[0019] Based on the above structure, the latch-type flip-top box detection device of this application further includes the following steps before the opening detector is activated:

[0020] S1, Place the injection molded product on the fixed frame, and store the box in the limiting groove. The limiting groove is used to position the injection molded product.

[0021] S2, the cutting device is started to cut off the flow channel formed part;

[0022] S3, the assembly device is activated, causing the box body and the lid to rotate and connect;

[0023] S4, the lid closing device is activated, causing the box body and lid to close together.

[0024] Therefore, it can achieve automatic separation and assembly of injection molded products, with a high degree of automation, thereby improving production efficiency.

[0025] Furthermore, in this application, a snap-on flip-top box detection device includes an ultrasonic cutting table with protrusions corresponding to the flow channel forming parts. It also includes a first driving assembly for driving the ultrasonic cutting table to move vertically. As a preferred embodiment, the ultrasonic cutting table is connected to an ultrasonic generator (not shown). The protrusions are the end execution ends of the ultrasonic cutting table. When the first driving assembly drives the protrusions to fit against the flow channel forming parts, the ultrasonic generator is activated, thus shaking the flow channel forming parts off between the box body and the lid.

[0026] Furthermore, in this application, a snap-on flip-top box detection device is provided, wherein the assembly device includes a push plate and a second drive assembly. The push plate is disposed on the side of the box cover away from the box body, and the second drive assembly is drivenly connected to the push plate for driving the push plate to move laterally.

[0027] The mounting bracket is provided with a sliding groove for the lateral movement of the storage box lid, and the lid is disposed within the sliding groove. As a preferred embodiment of this application, a push plate is driven to move by a second drive assembly to push the lid towards the box body until it is coupled to the pivot buckle and the pivot. The sliding groove is used to limit the lid from moving too far in the horizontal direction.

[0028] Furthermore, in this application, a snap-on flip-top box detection device includes a closing mechanism comprising a third drive assembly and a swing frame rotatably mounted on a fixed frame. The third drive assembly is drively connected to the swing frame to drive the swing frame to rotate on the fixed frame. A roller is provided at the end of the swing frame, extending along the width direction of the box lid. During the rotation of the swing frame, the roller pushes the box lid to rotate on the box body. As a preferred embodiment of this application, the third drive assembly drives the swing frame to flip, pushing the box lid to rotate on the box body, during which the roller contacts the box lid.

[0029] As can be seen from the above technical solution, the present invention has the following beneficial effects:

[0030] 1. This invention provides a detection device for a snap-on flip-top box. Based on the above structure, a limiting groove is used to limit the bottom of the box. The transmission frame, push frame, and lid form three movable links of a four-bar linkage. A preset first driving force is applied to the transmission frame by a lid-opening driver. The push frame transmits the force to the lid-opening groove through a push head. If the lid opens at this time, it is determined that the fastening component is not firmly coupled, and the product is unqualified; otherwise, the product is qualified. Therefore, it is possible to automatically detect the reliability of the fastening component coupling of the flip-top box.

[0031] 2. This invention provides a snap-on flip-top box inspection device, which enables the automatic separation and assembly of injection-molded flip-top boxes. After assembly, the reliability of the fastening components can be directly tested. It has the advantage of a high degree of automation. Attached Figure Description

[0048] Example 1

[0049] Combination Figure 1 and Figure 2 As shown, a snap-on flip box detection device is used to detect the quality of the flip box. The flip box includes a box body 11 and a box lid 12 that are rotatably connected to each other. The box body 11 and the box lid 12 are provided with a pair of corresponding fastening members. Specifically, the box body 11 has a locking protrusion 111 on the side away from the box lid 12, and the box lid 12 has a locking buckle 121 corresponding to the locking protrusion 111 on the side away from the box body 11. The locking protrusion 111 and the locking buckle 121 form a pair of fastening members. The box lid 12 is provided with an opening groove 1211.

[0050] Also includes:

[0051] The fixing frame 2 is provided with a limiting groove 210 at the bottom of the storage box 11;

[0052] It also includes a lid opening detector 7, which includes a lid opening driver, a transmission frame 72 and a pusher 73. The transmission frame 72 is rotatably mounted on the fixed frame 2 and is rotatably connected to the pusher 73. The pusher 73 has a push head 731 adapted to the lid opening groove 1211 at one end away from the transmission frame 72. When the lid 12 and the box body 11 are closed, the push head 731 abuts against the inside of the lid opening groove 1211. The lid opening driver is tractively connected to the transmission frame 72 and is used to apply a preset driving force to the transmission frame 72.

[0053] In this application, product quality includes the firmness of the coupling between a pair of fastening components when the lid 12 is closed to the box body 11. If the coupling is not firm, the product can be judged as unqualified. Based on the above structure, the transmission frame 72, the push frame 73, and the lid 12 form three movable links of a four-bar linkage. The opening driver applies a preset first driving force to the transmission frame 72, and the push frame 73 transmits the force to the opening slot 1211 through the push head 731. If the lid 12 opens at this time, it is judged that the fastening components are not firmly coupled and the product is unqualified; otherwise, the product is judged as qualified.

[0054] In this embodiment, the push head 731 is cylindrical with its axis parallel to the opening groove 1211, and the push head 731 is rotatably mounted at the end of the push frame 73.

[0055] In this embodiment, the lid opening driver is a cylinder 71. A pair of relatively telescopic components of the cylinder 71 are rotatably connected to the fixed frame 2 and the transmission frame 72, respectively. The cylinder 71 is set on the fixed frame 2 on the side of the box body 11 away from the lid 12.

[0056] By controlling the driving air pressure of cylinder 71, the stability of the driving force generated by the cover opening actuator can be ensured. In this embodiment, the cylinder body of cylinder 71 is rotatably mounted on the fixed frame 2, and the telescopic rod of cylinder 71 is rotatably connected to the transmission frame 72.

[0057] In this embodiment, a return spring 74 is also included. The return spring 74 is elastically connected to the push frame 73, and a limiting flange 212 is provided on the fixed frame 2.

[0058] When the cover opening driver is not started, the reset spring 74 presses the pusher 73 against the limit stop 212.

[0059] In this application, the limiting flange 212 is used to position the pusher 73 in the reset state. In the reset state, the pusher 73 is pressed against the limiting flange 212 by the elastic force applied by the reset spring 74 to ensure that the push head 731 on the pusher 73 can be in the opening groove 1211. In this embodiment, the limiting flange 212 is provided on the horizontal plate 21.

[0060] In this embodiment, the reset spring 74 is a tension spring, and the reset spring 74 is connected between the push frame 73 and the fixed frame 2.

[0061] In this embodiment, a suction nozzle 23 is also included. The suction nozzle 23 is disposed on the bottom surface of the limiting groove 210 and is connected to the vacuum generator through an air passage.

[0062] In this 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 external force.

[0063] Example 2

[0064] Combination Figure 3 and 4 As shown, when the flip box is not assembled, the box body 11 and the lid 12 are arranged horizontally, and the box body 11 and the lid 12 are connected by a flow channel forming part 13. Each of the box body 11 and the lid 12 is provided with a rotating connector, which includes a rotating shaft buckle 141 and a rotating shaft 142 respectively disposed on a pair of rotating connecting bodies on adjacent sides. The pair of rotating connecting bodies are the box body 11 and the lid 12; based on embodiment 1, combined with... Figure 5 and Figure 6 This embodiment also includes an assembly unit, which includes:

[0065] Cutting device 3 is used to cut off the flow channel forming part 13;

[0066] Assembly device 4 is used to move the box cover 12 until it is coupled with the pivot buckle 141 and the pivot 142;

[0067] The lid closing device 5 is used to flip the lid 12 so that it is coupled to a pair of fastening members.

[0068] Based on the above structure, the latch-type flip box detection device of this application further includes the following steps before the opening detector 7 is activated:

[0069] S1, place the injection molded product 1 on the fixing frame 2, and store the box body 11 in the limiting groove 210. The limiting groove 210 is used to position the injection molded product 1.

[0070] S2, the cutting device 3 is started to cut off the flow channel forming part 13;

[0071] S3, the assembly device 4 is activated, causing the box body 11 and the box cover 12 to rotate and connect;

[0072] S4, the lid closing device 5 is activated, causing the box body 11 and the lid 12 to close together.

[0073] Therefore, it can achieve automatic separation and assembly of injection molded product 1, with a high degree of automation, thereby improving production efficiency.

[0074] Combination Figure 7As shown, in this embodiment, the cutting device 3 includes an ultrasonic cutting table 31, which has protrusions 311 corresponding to the flow channel forming parts 13. It also includes a first driving assembly 32, which drives the ultrasonic cutting table 31 to move vertically. In this application, the ultrasonic cutting table 31 is connected to an ultrasonic generator (not shown). The protrusions 311 are the end execution ends of the ultrasonic cutting table 31. When the first driving assembly 32 drives the protrusions 311 to fit against the flow channel forming parts 13, the ultrasonic generator is activated, which shakes the flow channel forming parts 13 off between the box body 11 and the box cover 12. Specifically, the flow channel forming parts 13 are arranged in pairs. The cutting device 3 is located below the flow channel forming parts 13. The ultrasonic cutting table 31 has a baffle rod 312, the top of which is higher than the protrusions 311. When the protrusions 311 fit against the flow channel forming parts 13, the baffle rod 312 is located inside the flow channel forming parts 13. The baffle bar 312 is used to ensure that the flow channel forming part 13 falls outward, preventing it from falling inward and causing difficulty in material discharge. Furthermore, the fixing frame 2 includes a horizontal plate 21, and the ultrasonic cutting table 31 is slidably connected to the horizontal plate 21 in the vertical direction. The horizontal plate 21 has a groove adapted to the shape of the protrusion 311. The bottom of the ultrasonic cutting table 31 has a transmission protrusion 313. The first drive assembly 32 includes a first drive cylinder 321 and a transmission block 322. The transmission block 322 is mounted on the movable component of the first drive cylinder 321, and the fixed component of the first drive cylinder 321 is mounted on the bottom of the horizontal plate 21. The first drive cylinder 321 is used to drive the transmission block 322 to move laterally. The side of the transmission block 322 near the transmission protrusion 313 has a lifting guide surface 3221, and the transmission protrusion 313 abuts against the upper part of the lifting guide surface 3221. Based on the above structure, longitudinal space is saved and compactness is improved. Specifically, the lifting guide surface 3221 includes a horizontally arranged high section and a low section, with the high section located above the low section, and an arc-shaped transition surface between the high section and the low section. When the first drive cylinder 321 drives the transmission block 322 to move until the transmission protrusion 313 is in contact with the high section, the ultrasonic cutting table 31 rises until the protrusion 311 contacts the flow channel forming part 13. When the first drive cylinder 321 drives the transmission block 322 to move until it is in contact with the low section, the protrusion 311 descends below the cover 12 to allow space for the cover 12 to move laterally.

[0075] In this embodiment, the assembly device 4 includes a push plate 41 and a second drive assembly 42. The push plate 41 is disposed on the side of the lid 12 away from the box body 11. The second drive assembly 42 is connected to the push plate 41 for driving the push plate 41 to move laterally. The fixing frame 2 is provided with a sliding groove 211 for receiving the laterally moving lid 12, and the lid 12 is disposed in the sliding groove 211. The second drive assembly 42 drives the push plate 41 to move, thereby pushing the lid 12 towards the box body 11 until the pivot buckle 141 and the pivot 142 are coupled. The sliding groove 211 is used to limit the lid 12 from moving too far in the horizontal direction. Specifically, the sliding groove 211 is disposed on the fixing frame 2. A limiting pressure plate 411 extends from the upper end of the push plate 41, and the limiting pressure plate 411 extends beyond the front end of the push plate 41 to limit the lid 12 from moving upward. Before the cutting device 3 is started, the limiting pressure plate 411 moves above the box cover 12. After the cutting device 3 is started, when the flow channel forming part 13 and the protrusion 311 are attached, 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 attached. After the cutting is completed, during the process of the second drive assembly 42 driving 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 upward too far. In this embodiment, the second drive assembly 42 includes a second drive cylinder 421. The cylinder body of the second drive cylinder 421 is mounted on the push plate 41, and the telescopic rod of the second drive cylinder 421 is connected to the fixed frame 2.

[0076] In this embodiment, the lid-closing device 5 includes a third drive assembly 52 and a swing frame 51 rotatably mounted on the fixed frame 2. The third drive assembly 52 is connected to the swing frame 51 to drive the swing frame 51 to rotate on the fixed frame 2. The end of the swing frame 51 is provided with a roller 511, which extends along the width direction of the lid 12. During the rotation of the swing frame 51, the roller 511 is used to push the lid 12 to rotate on the box body 11. The third drive assembly 52 drives the swing frame 51 to flip, thereby pushing the lid 12 to rotate on the box body 11. During this process, the roller 511 contacts the lid 12. In this embodiment, the swing frame 51 includes a pair of swing arms 512, a roller 511 is rotatably mounted between the pair of swing arms 512, and the swing arms 512 are rotatably mounted on the fixed frame 2. A transmission gear 5121 is mounted on the swing arms 512 corresponding to their rotation axes. The third drive assembly 52 includes a third drive cylinder 521 and a rack frame 522. The rack frame 522 is connected to the movable component of the third drive cylinder 521, and a transmission rack 5221 is provided on the rack frame 522, which meshes with the transmission gear 5121. The third drive cylinder 521 drives the rack frame 522 to move, thereby driving the transmission gear 5121 to rotate, thus rotating the swing frame 51 to push a pair of engaging components to couple. When the pair of engaging components couple, the stroke of the third drive cylinder 521 can be limited, which has the advantage of simple control. In this embodiment, the rotation axis of the swing frame 51 is not concentric with the rotation axis of the lid 12. Therefore, during the process of the roller 511 pushing the lid 12 to flip, relative sliding will occur between the roller 511 and the lid 12. The swing arm 512 on the roller 511 can prevent scratching of the lid 12 during this process. Preferably, a flexible pad can be covered on the surface of the roller 511. If the quality of the molded product is poor or the rotating shaft 142 breaks during assembly, the gap between the box body 11 and the lid 12 will not be tight enough when a pair of fastening components are coupled. Therefore, the tightness of the fit between the box body 11 and the lid 12 after the lid 12 is closed on the box body 11 is an important indicator for detecting product quality.

[0077] Combination Figure 5 , Figure 6 and Figure 8The device also includes a gap detection device 6, which comprises a plug 61, a pull actuator 62, and a pressure sensor 68. A limiting plate 22 is provided on one side of the box body 11, and the detection end of the pressure sensor 68 is located on the limiting plate 22 near the box body 11. Before the lid closing device 5 is activated, the plug 61 is placed on the box body 11. After the lid closing device 5 is activated, the plug 61 is clamped between the box body 11 and the lid 12. The pull actuator 62 is connected to the plug 61 and is used to pull the plug 61 from the box body 11 towards the limiting plate 22. Based on the above device, the principle is that after the lid closing device 5 is activated, the plug 61 is clamped between the box body 11 and the lid 12. By pulling the plug 61 through the pull actuator 62, the box body 11 will not move due to the limiting plate 22. The pressure sensor 68 detects the pressure generated by the box body 11 during this process to determine whether the box body 11 and the lid 12 are tightly pressed together. If the pressure sensor 68 detects a pressure greater than a preset value, it is determined that the box body 11 and the lid 12 are tightly pressed together, and the product is qualified. If the pressure sensor 68 detects a pressure less than the preset value, the product is determined to be unqualified. In this embodiment, the thickness of the plug 61 is 0.2mm. After the lid opening detector 7 completes its detection, the lid opening driver applies a preset second driving force to ensure that the lid 12 is opened. At this time, the flipping frame drive device 65 can drive the flipping frame 63 to reset from the first posture to the second posture.

[0078] Specifically, the pull actuator 62 includes a pull drive cylinder 621 and a sliding seat 622 connected to the movable component of the pull drive cylinder 621. The sliding seat 622 is connected to the plug 61. The pull drive cylinder 621 drives the sliding seat 622 to move, thereby moving the plug 61.

[0079] In other embodiments, the gap detection device 6 further includes a flipping frame 63, which is rotatably mounted on the fixed frame 2, and a flipping frame drive device 65, which is connected to the flipping frame 63 in a transmission manner. The plug 61 and the pull driver 62 are mounted on the flipping frame 63.

[0080] The tilting frame drive device 65 is used to drive the tilting frame 63 to rotate, so that the tilting frame 63 switches between the first posture and the second posture.

[0081] In the first position, the plug 61 is attached to the upper end of the box 11;

[0082] In the second position, the plug 61 is located outside the box 11. In the initial state, the flipping frame 63 is in the second position, and the box 11 is placed in the limiting groove 210 to make room for placing the box 11 in the limiting groove 210;

[0083] After the box 11 is placed in the limiting groove 210, the flipping frame drive device 65 drives the flipping frame 63 to rotate to the first posture, and the plug 61 presses against the upper end of the box 11. The flipping frame drive device 65 is a motor, and the flipping frame 63 and the flipping frame drive device 65 are connected by a sprocket-chain transmission.

[0084] Specifically, the fixed frame 2 is provided with a limiting part. When the flipping frame 63 is in the first posture, the flipping frame 63 abuts against the limiting part. The limiting part is used to position the flipping frame 63, and after the pull driver 62 is started, it ensures that the flipping frame 63 stops in the second posture. In this embodiment, the limiting part is the upper end surface of the horizontal plate 21.

[0085] Specifically, a winding shaft 64 is rotatably mounted on the flipping frame 63. The winding shaft 64 is located on the side of the housing 11 away from the limiting plate 22. One end of the plug 61 is wound on the winding shaft 64, and the other end is connected to the pull driver 62. A winding shaft driver 66 is installed on the flipping frame 63, and the winding shaft driver 66 is connected to the winding shaft 64 in a driving connection. In this application, the winding shaft 64 serves to a certain extent to store the plug 61. After a certain number of uses, the plug 61 at the front end will wear out, affecting the detection accuracy. At this time, the front part of the plug 61 is cut off, and the unworn plug 61 at the rear end is connected to the limiting plate 22. Furthermore, before the pull driver 62 is activated, the winding shaft driver 66 locks the winding shaft 64 to prevent it from rotating. During the process of the pull driver 62 pulling the plug 61, the winding shaft driver 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 driver 66 drives the winding shaft 64 to rotate, thereby pulling the sliding seat 622 to reset. During this process, the pull drive cylinder 621 is in a disabled state. In this embodiment, the winding shaft driver 66 is a stepper motor, and the winding shaft driver 66 and the winding shaft 64 are connected by a synchronous pulley-synchronous belt drive. 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 rotating with the plug 61. The specific tension controller may be a coil spring (not shown), which is provided between the winding shaft 64 and the flipping frame 63 to apply a spring force to the winding shaft 64 in the opposite direction to R, so as to ensure the synchronicity of the rotation when the winding shaft 64 is pulled.

[0086] Specifically, the flipping frame 63 is provided with a positioning roller 67. When the flipping frame 63 is in the first posture, the positioning roller 67 is located on the side of the box body 11 away from the limiting plate 22. The positioning roller 67 is pressed onto 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.

[0087] Specifically, the tilting frame 63 includes a pair of side plates 631, with a pair of connecting plates 632 fixedly disposed between the side plates 631. The connecting plates 632 extend along the sliding direction of the sliding seat 622, and each connecting plate 632 has a guide rail mounting surface. The pair of guide rail mounting surfaces are perpendicular to each other, and guide rails 6321 are mounted on the guide rail mounting surfaces. The sliding seat 622 is slidably mounted on the guide rails 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 tilting frame 63 during the tilting and switching process. Specifically, when the tilting frame 63 is in the first posture, one of the connecting plates 632 is below the sliding seat 622.

[0088] The technical principles of the present invention have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of the invention and should not be construed as limiting the scope of protection of the invention in any way. Based on this explanation, those skilled in the art can conceive of other specific embodiments of the invention without creative effort, and these embodiments will all fall within the scope of protection of the present invention.
