[0010] The beneficial effects of the present invention are: Compared with the existing lock buckle preparation, the present invention adopts fully automatic injection molding.

The injection molding adopts secondary injection molding, which is the injection molding shell and the first injection molding cover plate and the second injection molding cover plate in turn, and finally the grabbing and transfer are carried out through the transfer mechanism.

After the transfer, it enters the circulation transmission mechanism, and performs detection, rejection, replenishment, marking and unloading in turn, realizing fully automated preparation, saving manpower and material resources, and improving production efficiency.

[0011] The automated production line of the present invention realizes the full-process automation of the lock buckle from raw materials to finished products by integrating multiple links such as feeding, placing, picking, injection molding, transfer, cyclic transmission, detection, replenishing, marking and unloading.

Especially in the injection molding link, through the precise secondary injection molding process, the injection molded shell is molded once to fix the locking shaft and the locking sleeve, and the first injection molded cover plate and the second injection molded cover plate are molded twice, which not only ensures the stability and reliability of the lock buckle structure, but also greatly shortens the production time of a single lock buckle.

First, the locking fixed shaft and the locking shaft sleeve are firmly covered together by the injection molding shell (including the locking plug shell and the locking shaft shell) through the primary injection molding, thereby forming the basic structure of the lock buckle. Subsequently, secondary injection molding is performed to form the first injection molding cover plate and the second injection molding cover plate respectively, and the two ends of the lock buckle are encapsulated. This secondary injection molding technology not only enhances the structural strength of the lock buckle, but also improves its sealing performance, effectively prevents the intrusion of external factors such as moisture and dust, and prolongs the service life of the lock buckle.

This embodiment adopts fully automatic injection molding, and the feeding part adopts automation to distinguish the locking fixed shaft 101 and the locking sleeve 103 of the embedded parts, so as to facilitate the subsequent grabbing and classification and put them into the injection molding equipment for injection molding. The injection molding adopts secondary injection molding, which is the injection molding shell and the first injection molding cover plate 104 and the second injection molding cover plate 105 in sequence, and finally the transfer mechanism 5 is used to grab and transfer.

[0021] The automated production line of the present invention realizes the full-process automation of the lock buckle from raw materials to finished products by integrating multiple links such as feeding, placing on a plate, picking up materials, injection molding, transferring, circulating transmission, testing, replenishing materials, marking and unloading materials. Compared with the traditional manual operation or semi-automatic production method, this highly integrated automated production mode greatly shortens the production cycle, reduces manual intervention, and thus significantly improves production efficiency. Especially in the injection molding link, through the precise secondary injection molding process, the injection molded shell is molded once to fix the locking fixed shaft 101 and the locking shaft sleeve 103, and the first injection molded cover plate 104 and the second injection molded cover plate 105 are molded twice, which not only ensures the stability and reliability of the lock buckle structure, but also greatly shortens the production time of a single lock buckle.

[0022] The fixed shaft feeding assembly 11 and the sleeve feeding assembly 12 in the feeding mechanism 1 of the present invention ensure the accurate feeding of the locking fixed shaft 101 and the locking sleeve 103, avoiding material confusion or damage. The swing plate mechanism 2 can accurately place the locking fixed shaft 101 and the locking sleeve 103 on the swing plate material rack 23 at a predetermined position through the coordinated work of the swing plate manipulator 21 and the swing plate drive assembly 22, providing good preconditions for subsequent injection molding operations. This precise positioning not only improves assembly efficiency, but also ensures the precise matching between the various components of the lock, thereby improving the overall quality and durability of the lock.

[0023] The injection molding mechanism 4 of the present invention is the core part of the device, which adopts the secondary injection molding technology. First, the locking fixed shaft 101 and the locking shaft sleeve 103 are firmly wrapped together by a primary injection molding of the injection molding shell (including the locking plug shell and the locking shaft shell), forming the basic structure of the lock. Subsequently, secondary injection molding is performed to form the first injection molding cover plate 104 and the second injection molding cover plate 105 respectively, and the two ends of the lock are encapsulated. This secondary injection molding technology not only enhances the structural strength of the lock, but also improves its sealing performance, effectively prevents the intrusion of external factors such as moisture and dust, and prolongs the service life of the lock.

[0024] The design of the swing plate rack 23 takes full account of production efficiency and flexibility.

[0027] See also Fig.10As shown, the fixed shaft feeding assembly 11 includes a fixed shaft feeding bracket 111, a fixed shaft feeding hopper 112, a fixed shaft feeding tray 113, a fixed shaft straight vibration track 114 and a fixed shaft positioning module 115. The fixed shaft feeding hopper 112 is arranged at the top end of the fixed shaft feeding bracket 111. A first vibrator 1121 is arranged at the bottom of the fixed shaft feeding hopper 112 for conveying the locked fixed shaft 101 toward the fixed shaft feeding tray 113. The fixed shaft feeding tray 113 is used to convey the locked fixed shaft 101 toward the fixed shaft straight vibration track 114. The fixed shaft positioning module 115 is connected to the discharge end of the fixed shaft straight vibration track 114 for locking the fixed shaft 101 in position. Specifically, the sleeve feeding assembly 12 includes a sleeve feeding bracket 121, a sleeve feeding hopper 122, a sleeve feeding tray 123, a sleeve direct vibration track 124, and a sleeve positioning module 125. The sleeve feeding hopper 122 is arranged at the top of the sleeve feeding bracket 121. The bottom of the sleeve feeding hopper 122 is provided with a second vibrator 1221 for conveying the locking sleeve 102 toward the sleeve feeding tray 123. The sleeve feeding tray 123 is used to convey the locking sleeve 102 toward the sleeve direct vibration track 124. The sleeve positioning module 125 is connected to the discharge end of the sleeve direct vibration track 124 for positioning the locking sleeve 102. In this embodiment, the fixed shaft feeding assembly 11 and the sleeve feeding assembly 12 both adopt the vibration feeding principle, and the locking fixed shaft 101 and the locking sleeve 102 are effectively conveyed to the subsequent processing link in a preset direction and rhythm through the feeding hopper vibrator 1121. This design significantly reduces manual intervention, realizes fully automated feeding from raw material storage to processing stations, and greatly improves production efficiency. At the same time, the application of the direct vibration track ensures the stability and continuity of materials during transportation, avoids production interruptions caused by material blockage or dislocation, and further ensures the stable operation of the production line. As key components of this technical solution, the fixed shaft positioning module 115 and the sleeve positioning module 125 are tightly connected to the discharge ends of the fixed shaft direct vibration track 114 and the sleeve direct vibration track 124, respectively. These modules use advanced positioning technology to accurately capture and lock the locked fixed shaft 101 and the locked sleeve 102 output from the direct vibration track to ensure their precise position before entering the injection molding or assembly process. This high-precision positioning not only improves the matching degree of the assembly parts and reduces the product defective rate caused by positioning errors, but also provides the possibility of realizing more complex lock buckle 10 structural design and higher standards of assembly accuracy. Key components in the fixed shaft feeding assembly 11 and the sleeve feeding assembly 12, such as the feeding hopper vibrator 1121, the straight vibration track and the positioning module, are all made of high-quality materials and processed using advanced technology to ensure long-term stability and reliability. This not only extends the service life of the equipment, but also reduces downtime caused by equipment failure, thereby reducing maintenance costs.

[0028] The sleeve positioning module 125 and the fixed shaft positioning module 115 are arranged in parallel, and the swing plate manipulator 21 is used to simultaneously grab the locked fixed shaft 101 and the locked shaft sleeve 102 on the sleeve positioning module 125 and the fixed shaft positioning module 115. In this embodiment, the swing plate manipulator 21 can accurately and quickly move between the sleeve positioning module 125 and the fixed shaft positioning module 115, and grab the locked fixed shaft 101 and the locked shaft sleeve 102 at the same time, reducing the manual operation links and improving production efficiency. Secondly, this scheme ensures the accuracy and stability of the feeding of the lock 10. The sleeve positioning module 125 and the fixed shaft positioning module 115 can accurately position and fix the locked fixed shaft 101 and the locked shaft sleeve 102, avoiding the problem of feeding errors or instability caused by inaccurate positioning, thereby improving the reliability and stability of the injection molding transfer equipment.

Specifically, the swing plate driving assembly 22 includes a swing plate driving base 221, a swing plate rotating cylinder 222, and a swing plate limiting element 223, wherein the swing plate rotating cylinder 222 is disposed on the swing plate driving base 221, and the swing plate limiting element 223 is used to limit the swing plate material rack 23. In this embodiment, the XYZ transmission module 211 ensures the flexible positioning and rapid movement of the swing plate material taking element 212 in three-dimensional space, so that the first material taking slot 2121 can be accurately aligned with the locking fixed shaft 101, and the second material taking slot 2122 can be accurately aligned with the locking sleeve 102, thereby achieving high precision and high efficiency in material grabbing. At the same time, the ingenious design of the swing plate material taking element 212 allows the grabbing of two different materials to be completed in one operation, further shortening the production cycle. In addition, the introduction of the swing plate drive assembly 22, especially the setting of the swing plate rotating cylinder 222, provides a stable rotational driving force for the swing plate manipulator 21, so that the material can be smoothly transferred to the specified position after grabbing, and the addition of the swing plate limiting element 223 effectively prevents the swing plate material rack 23 from deflecting or shaking during the rotation process, ensuring the stability and safety of material transfer.
