Therefore, the drawings only show the components related to the present invention and are not drawn according to the number, shape and size of the components in actual implementation. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0019] In this embodiment of the invention, all directional indicators (such as up, down, left, right, front, back, horizontal, vertical, etc.) are only used to explain the relative positional relationship and movement of each component in a specific posture. If the specific posture changes, the directional indicator will also change accordingly.

[0020] Due to installation errors and other reasons, the parallel relationship referred to in the embodiments of this utility model may actually be an approximate parallel relationship, and the perpendicular relationship may actually be an approximate perpendicular relationship.

[0021] Example 1:

[0022] like Figure 1As 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.

[0023] like Figures 2-4 As shown, a latch feeding mechanism 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 a 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 subsequent spring latch assembly mechanism for latch feeding.

[0024] The lock assembly machine of this application is equipped with two sets of lock tongue feeding mechanisms. The two sets of lock tongue feeding mechanisms respectively realize the feeding of the first lock tongue and the second lock tongue, thereby realizing the double-tongue lock tongue feeding of the first lock tongue and the second lock tongue.

[0025] 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.

[0026] 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.

[0027] 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.

[0028] The latch feeding mechanism also includes a latch feeding sensing structure, which is fixed in 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.

[0029] The latch feeding process of latch feeding assembly 21 is as follows:

[0030] When the latch 7 is introduced into the moving channel 2135 from the latch guide 2133 in a defined direction, the latch pin 2121 of the upper latch pin 212 engages with the second groove 74 of the latch, and the latch feeding drive 211 is activated to push the latch 7 to the subsequent spring latch assembly mechanism for latch feeding using the upper latch pin.

[0031] This invention achieves automatic loading of the lock tongue through a lock tongue loading drive, a lock tongue pin, and a lock tongue loading fixture, which not only improves the high-precision assembly of the lock tongue but also enhances the assembly quality.

[0032] This invention features a guide groove in the latch guide component. The latch enters the moving channel from the guide groove, and the shape of the guide groove matches the latch, thereby restricting the direction of the latch when it enters the moving channel. At the same time, the end of the upper latch pin is provided with a locking slot, which engages with the second groove to form a fit, preventing the latch from rotating during the movement of the upper latch pin, and facilitating subsequent latch assembly.

[0033] 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.
