[0028] Example 1:

[0029] like Figures 2-8 As shown, a latch assembly mechanism includes a spring feeding mechanism 20, a first latch feeding mechanism 21, a second latch feeding mechanism 22, and a spring latch assembly mechanism 23. The spring latch assembly mechanism 23 is connected to the spring feeding mechanism 20, the first latch feeding mechanism 21, and the second latch feeding mechanism 22.

[0030] like Figure 1 As shown, the latch 7 has a first protrusion 71 and a second protrusion 72, and a first groove 73 is formed between the first protrusion 71 and the second protrusion 72. The end of the latch 7 has a second groove 74. The latch 7 is a conventional structure and this application has not improved it.

[0031] The spring feeding mechanism 20, the first latch feeding mechanism 21, the second latch feeding mechanism 22, and the spring latch assembly mechanism 23 are installed on the latch mounting plate 271.

[0032] The spring feeding mechanism 20 includes a spring feeding drive 201, a spring feeding fixture 202, a spring pushing drive 203, and a spring pushing pin 204. The spring feeding fixture 202 is connected to the spring feeding drive 201, the spring pushing drive 203 is connected to the spring pushing pin 204, and the spring feeding fixture 202 is connected to the spring tray, which is a conventional vibratory feeder. The spring feeding fixture 202 receives the springs fed by the spring tray. The spring feeding drive 201 controls the spring feeding fixture 202 to move to the spring feeding station. The spring feeding station is located in front of the spring pushing pin 204. The spring pushing drive 203 controls the spring pushing pin 204 to move and transport the springs in the spring feeding fixture 202 to the spring locking tongue assembly mechanism 23.

[0033] The spring feeding drive 201 includes a spring feeding cylinder 2011, a spring feeding slide rail 2012, and a spring feeding slider 2013. The spring feeding cylinder 2011 and the spring feeding slide rail 2012 are fixed on the locking tongue mounting plate 271. The spring feeding slider 2013 is slidably connected to the spring feeding slide rail 2012. The spring feeding fixture 202 is fixed to the spring feeding slider 2013 through a spring feeding fixture connector. The spring feeding cylinder 2011 is connected to the spring feeding fixture 202. When the spring feeding cylinder 2011 is activated, it drives the spring feeding fixture 202 to slide along the spring feeding slide rail 2012.

[0034] The spring feeding fixture 202 is provided with a spring hole 2021, which is connected to the discharge port of the spring tray. The springs in the spring tray are transported from the discharge port to the spring hole 2021.

[0035] The spring feeding mechanism 20 also includes a spring sensing structure, which is installed inside or opposite to the spring hole 2021. The spring sensing structure senses whether a spring is present in the spring hole 2021. If a spring is present, the spring sensing structure sends a signal to the spring feeding drive 201, which then initiates the feeding operation. If no spring is present in the spring hole 2021, the spring sensing structure issues an alarm or sends a warning to the control panel or other equipment. The spring sensing structure can be a conventional photoelectric sensor, pressure sensor, etc. The sensing principle, structure, and installation can be determined according to actual needs. In this embodiment, the spring sensing structure is a photoelectric sensor. The latch mounting plate 271 is fixed with a sensing element fixing member 272, which has a sensing element fixing hole opposite to the spring hole 2021. The spring sensing structure is fixed to the sensing element fixing member 272 and faces the spring hole 2021 through the sensing element fixing hole, thereby achieving the purpose of sensing whether a spring is present in the spring hole 2021.

[0036] The spring pusher drive 203 includes a spring pusher cylinder 2031, which is fixed to the locking tongue mounting plate 271 via a pusher base plate. The spring pusher 204 is fixed to the output shaft of the spring pusher cylinder 2031 and is driven to reciprocate by the spring pusher cylinder 2031.

[0037] The spring pusher drive 203 also includes a spring pusher guide block 205, which is fixedly mounted on the latch mounting plate 271. The spring pusher guide block 205 is fixedly provided with a spring pusher guide tube 2051, and the spring pusher pin 204 slides through the spring pusher guide tube 2051. The spring pusher guide block 205 supports the spring pusher pin 204 and guides its movement.

[0038] The spring feeding mechanism 20 may also include a limiting structure 206, which is used to limit the stroke and positioning of the spring feeding cylinder 2011. In other embodiments, the travel stroke of the spring feeding cylinder 2011 may also be set, but this application does not limit it.

[0039] The first latch feeding mechanism 21 and the second latch feeding mechanism 22 are distributed on both sides of the spring latch assembly mechanism 23 and are fixedly connected to the latch mounting plate 271. The first latch feeding mechanism 21 is used to feed the first latch, and the second latch feeding mechanism 22 is used to feed the second latch. The first latch feeding mechanism 21 and the second latch feeding mechanism 22 realize the feeding of the double latches of the first latch and the second latch. The first latch feeding mechanism 21 and the second latch feeding mechanism 22 have the same structure. In this embodiment, the first latch feeding mechanism 21 is used as an example for explanation.

[0040] The first latch feeding mechanism 21 includes a latch feeding drive 211, a latch pin 212, and a latch feeding fixture 213. The latch feeding drive 211 is fixedly connected to the latch pin 212, and the latch feeding fixture 213 is connected to the latch material tray. The latch material tray is a conventional vibratory feeder. The latch feeding fixture 213 receives the latches fed by the latch material tray. The latch feeding drive 211 controls the latch pin 212 to move and feed the latches in the latch feeding fixture 213 to the spring latch assembly mechanism 23.

[0041] The latch feeding drive 211 is fixedly connected to the latch mounting plate 271 via the latch feeding fixture, and the latch feeding jig 213 is fixedly connected to the latch mounting plate 271 via the latch feeding base.

[0042] The latch loading fixture 213 includes a first latch fixture 2131, a second latch fixture 2132, and a latch guide 2133. The second latch fixture 2132 and the latch guide 2133 are respectively fixed to the first latch fixture 2131. The three fixtures form a moving channel 2135 for the latch 7 to move. The latch guide 2133 is provided with a guide groove 2134, which is connected to the moving channel 2135. The latch 7 enters the moving channel 2135 from the guide groove 2134. The shape of the guide groove 2134 matches the latch 7, thereby restricting the direction of the latch 7 when it enters the moving channel 2135.

[0043] The upper locking pin 212 has a latch 2121 at its end, which engages with the second groove 74 to form a fit, preventing the locking tongue 7 from rotating during the process of the upper locking pin 212 pushing the locking tongue 7 to move, thus facilitating the subsequent assembly of the locking tongue.

[0044] Specifically, the guide groove 2134 restricts the guiding of the latch 7: the cross-sectional shape of the guide groove 2134 matches the cross-section of the latch 7, that is, the guide groove 2134 has a slot to accommodate the first protrusion 71 and the second protrusion 72. The guide groove 2134 has a guide post. The latch guide 2133 is connected to the outlet of the latch material tray. When the latch enters the guide groove of the latch guide 2133 from the outlet, the guide post is inserted into the first slot 73, and the first protrusion 71 and the second protrusion 72 are inserted into the slot. At this time, the direction of the latch 7 entering the guide groove and the moving channel 2135 is limited.

[0045] The first latch feeding mechanism 21 also includes a latch feeding sensing structure. The latch feeding sensing structure is fixed to the latch feeding fixture 213 to sense whether there is a latch in the moving channel 2135. If there is a latch in the moving channel 2135, the latch feeding sensing structure sends a signal to the latch feeding drive 211, and the latch feeding drive 211 starts to perform the feeding operation. If there is no latch in the moving channel 2135, the latch feeding sensing structure issues an alarm or sends a warning to the control panel or other equipment. The latch feeding sensing structure can use conventional photoelectric sensors, pressure sensors, etc. The sensing principle, structure, and installation can be determined according to actual needs.

[0046] The first latch feeding mechanism 21 latch feeding process is as follows:

[0047] When the latch 7 is introduced into the moving channel 2135 from the latch guide 2133 in a defined direction, the latch pin 2121 engages with the second groove 74 of the latch, and the latch feeding drive 211 is activated to push the latch 7 to the spring latch assembly mechanism 23 using the latch pin.

[0048] The spring latch assembly mechanism 23 includes a latch assembly drive 231 and a latch assembly component 232. The latch assembly drive 231 is connected to the latch assembly component 232. The latch assembly component 232 is driven by the latch assembly drive 231 to dock with the spring feeding mechanism 20, the first latch feeding mechanism 21, and the second latch feeding mechanism 22, thereby realizing the feeding and assembly of the spring of the spring feeding mechanism 20, the first latch of the first latch feeding mechanism 21, and the second latch of the second latch feeding mechanism 22.

[0049] The latch assembly drive 231 includes a latch assembly shift cylinder 2311, a latch assembly shift slide rail 2312, and a latch assembly shift slider 2313. The latch assembly shift cylinder 2311 and the latch assembly shift slide rail 2312 are fixed on the latch mounting plate 271. The latch assembly shift slider 2313 is slidably connected to the latch assembly shift slide rail 2312. The latch assembly component 232 is fixed on the latch assembly shift slider 2313 through the latch assembly advance and retreat base plate 2314. The latch assembly shift cylinder 2311 is connected to the latch assembly advance and retreat base plate 2314. When the latch assembly shift cylinder 2311 is activated, it drives the latch assembly component 232 to slide along the latch assembly shift slide rail 2312.

[0050] The latch assembly drive 231 controls the latch assembly component 232 to move in three stations, specifically including a spring feeding station, a first latch feeding station, and a second latch feeding station. The latch assembly drive 231 controls the latch assembly component 232 to move to the spring feeding station, where the latch assembly component 232 docks with the spring feeding mechanism 20. The latch assembly drive 231 then controls the latch assembly component 232 to move to the first latch feeding station, where the latch assembly component 232 docks with the first latch feeding mechanism 21. The latch assembly drive 231 then controls the latch assembly component 232 to move to the second latch feeding station, where the latch assembly component 232 docks with the second latch feeding mechanism 22. The second latch feeding station also serves as the latch spring feeding station. After the first latch, spring, and second latch are assembled by the latch assembly component 232, they are simultaneously pushed to the subsequent latch feeding mechanism by the second latch feeding mechanism 22.

[0051] The latch assembly component 232 includes a latch assembly fixture 2321, a first push-lock structure, and a second push-lock structure. The latch assembly fixture 2321 has a receiving cavity 2322, which is configured as a feeding channel for the spring, the first latch, and the second latch. The first push-lock structure and the second push-lock structure are movably disposed in the latch assembly fixture 2321, and the first push-lock structure and the second push-lock structure respectively restrict the movement of the first latch and the second latch in the feeding channel.

[0052] The latch assembly fixture 2321 is fixedly mounted on the latch assembly advance and retreat base plate 2314. The first push-lock structure and the second push-lock structure are located on both sides of the latch assembly fixture 2321 and are fixedly connected to the latch assembly advance and retreat base plate 2314.

[0053] The first push-lock structure includes a first push-lock cylinder 2323 and a first push-lock plate 2324. The first push-lock cylinder 2323 is opposite to the first push-lock plate 2324. The first push-lock cylinder 2323 is fixed on the latch assembly advance and retraction base plate 2314. The first push-lock plate 2324 is driven by the first push-lock cylinder 2323 to move towards the latch assembly fixture 2321. The first push-lock plate 2324 is provided with a first protrusion. After the first push-lock plate 2324 is pressed by the first push-lock cylinder 2323, the first protrusion is inserted into the receiving cavity 2322 to limit the first latch.

[0054] The latch assembly fixture 2321 is provided with a first push-lock groove, and a first push-lock plate 2324 is inserted into the first push-lock groove and can move in the first push-lock groove. The first push-lock plate 2324 and the latch assembly fixture 2321 are connected by a spring.

[0055] The second push-lock structure includes a second push-lock cylinder 2325 and a second push-lock plate 2326. The second push-lock cylinder 2325 is opposite to the second push-lock plate 2326. The second push-lock cylinder 2325 is fixed on the latch assembly advance and retraction base plate 2314. The second push-lock plate 2326 is driven by the second push-lock cylinder 2325 to move towards the latch assembly fixture 2321. The second push-lock plate 2326 is provided with a second protrusion. After the second push-lock plate 2326 is pressed by the second push-lock cylinder 2325, the second protrusion is inserted into the receiving cavity 2322 to limit the second latch.

[0056] The latch assembly fixture 2321 is provided with a second push-lock slot, and the second push-lock plate 2326 is inserted into the second push-lock slot and can move in the second push-lock slot. The second push-lock plate 2326 and the latch assembly fixture 2321 are connected by a spring.

[0057] The spring latch assembly mechanism 23 may also include a latch limiting structure 234. The latch limiting structure 234 is disposed on the latch assembly fixture 2321 and located above the receiving cavity 2322. It is used to limit the movement of the latch in the height direction, so as to prevent the latch from deviating in the height direction during the feeding and pushing process, and effectively improve the efficiency of latch feeding and pushing.

[0058] The latch limiting structure 234 includes a latch fixture 2341 and a latch assembly clamping member 2342. The latch assembly clamping member 2342 is connected to the latch assembly fixture 2321. The latch assembly clamping member 2342 is disposed in the latch fixture 2341 and connected by a spring. The latch assembly clamping member 2342 is opposite to the receiving cavity 2322 and is in contact with the latch. The latch assembly clamping member 2342 is distributed along the latch feeding and pushing path. The latch assembly clamping member 2342 presses the latch from above.

[0059] The locking tongue fixture 2341 and the locking tongue assembly clamping part 2342 are connected, specifically:

[0060] The latch fixture 2341 has a mounting hole 23411. The latch assembly clamping member 2342 is adapted to be installed in the mounting hole 23411. The mounting hole 23411 has a T-shaped structure, and the latch assembly clamping member 2342 has a matching T-shaped structure. During installation, the latch assembly clamping member 2342 slides in the mounting hole 23411, thereby restricting the height of the latch assembly clamping member 2342. The latch fixture 2341 has a pin hole 23412, and the latch assembly clamping member 2342 has a pin through hole 23421. The pin hole 23412 and the pin through hole 23421 are opposite to each other and are connected by a pin, thereby restricting the front and rear directions of the latch assembly clamping member 2342 and achieving stable installation of the latch assembly clamping member 2342 in the latch fixture 2341.

[0061] The latch fixture 2341 has two sets of spring mounting holes 23413, which communicate with the mounting holes 23411. Springs are installed in the spring mounting holes 23413, connecting the latch assembly clamping member 2342 to the latch fixture 2341. The latch assembly clamping member 2342 uses the spring force to contact the latch, preventing it from moving in the height direction. When the latch is subjected to force for feeding or pushing, because the spring force is small and the direction of the external force is different from the spring force, it can overcome the spring force and push the latch back and forth.

[0062] The spring latch assembly mechanism 23 may also include a latch limiting structure 233, which is used to limit the stroke and positioning of the latch assembly shift cylinder 2311. In other embodiments, the movement stroke of the latch assembly shift cylinder 2311 may also be set, but this application does not limit it.

[0063] The assembly process of the latch and spring is as follows:

[0064] The first push-lock cylinder 2323 is activated, pushing the first push-lock plate 2324 towards the latch assembly fixture 2321. The first protrusion is inserted into the receiving cavity. After the first latch feeding mechanism 21 feeds the first latch, the latch assembly shift cylinder 2311 drives the latch assembly fixture 2321 to move to the first latch feeding station. The latch feeding drive 211 is activated, pushing the first latch into the receiving cavity 2322 in the direction of arrow b. The first latch feeding mechanism 21 is reset. After the spring feeding mechanism 20 feeds the spring, the latch assembly shift cylinder 2311 drives the latch assembly fixture 2321 to move to the spring feeding station. The spring push cylinder 2031 drives the spring push pin 204 in the direction of arrow a to push the spring into the receiving cavity 2322. The second push-lock cylinder 23235 pushes the second push-lock plate 232. 6. Move towards the latch assembly fixture 2321. The second protrusion is inserted into the receiving cavity. After the second latch is fed onto the second latch feeding mechanism 22, the latch assembly displacement cylinder 2311 drives the latch assembly fixture 2321 to move to the second latch feeding station. The latch feeding drive of the second latch feeding mechanism 22 starts and pushes the second latch to the receiving cavity 2322 in the direction of arrow a. At this time, the first push buckle cylinder 2323 and the second push buckle cylinder 2325 are reset. The first push buckle plate 2324 and the second push buckle plate 2326 are reset under the action of spring restoring force. The first protrusion and the second protrusion move away from the receiving cavity 2322. The latch feeding drive of the second latch feeding mechanism 22 continues to run. The latch pin continues to move and pushes the second latch, the spring and the first latch to the subsequent latch feeding mechanism.

[0065] This invention achieves double-tongue lock tongue assembly through a lock tongue assembly device, which not only improves the high-precision assembly of the lock tongue and enhances the assembly quality, but also achieves efficient assembly of the lock tongue and improves assembly efficiency. If necessary, it can be modified to adapt to single-tongue assembly.

[0066] Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort should fall within the protection scope of this utility model.
