[0051] Further, the support table 2 is provided with a distributing mechanism 8 used for staggered arrangement and combination of the pin 23, the flat pin 24, the spring 25 and the aluminum ball 26 and loading the combined components into the grooves 22; by operating the distributing mechanism 8, the pin 23, the flat pin 24, the spring 25 and the aluminum ball 26 are staggered arranged and combined, the combined pin 23, flat pin 24, spring 25 and aluminum ball 26 are arranged from bottom to top in sequence, so as to be loaded into the grooves 22 on the lock cylinder 20 at one time; in addition, the number of groups of the pin 23, the flat pin 24, the spring 25 and the aluminum ball 26 staggered arranged and combined by the distributing mechanism 8 is consistent with the number of the grooves 22, when the grooves 22 are provided with four, the distributing mechanism 8 needs to staggered arrange and combine four groups of the above components, after the combination is completed, the four groups of components are carried to the installation station 12 and placed above the lock cylinder 20 to be installed, which can load the four groups of components into different grooves 22 at one time, thereby improving the efficiency of the pin tumbler lock installation.

[0052] As Figure 4As shown, the distributing mechanism 8 comprises a support frame 81, a regulating plate 83 is transversely slidably arranged on the top of the support frame 81, and a discharging station 84 for continuously discharging the components of the tumbler lock (i.e. the tumbler 23, the flat tumbler 24, the spring 25 and the aluminum ball 26) is arranged on the regulating plate 83. By controlling the transverse movement of the regulating plate 83 on the top of the support frame 81, the discharging position of the discharging station 84 can be adjusted to facilitate cooperation with the subsequent mechanism. Specifically, a slide rail 82 is arranged transversely on the top of the support frame 81, the regulating plate 83 is slidably arranged on the slide rail 82, and in order to control the sliding of the regulating plate 83 on the slide rail 82, a lead screw 87 is arranged on the top of the support frame 81 in the same direction as the length direction of the slide rail 82, the lead screw 87 is threadedly connected with the regulating plate 83, a servo motor 88 is arranged on the side of the support frame 81, the output shaft of the servo motor 88 is drivingly connected with one end of the lead screw 87 through a transmission member 89. By driving the lead screw 87 to rotate through the transmission of the servo motor 88 and the transmission member 89, the transverse sliding of the regulating plate 83 on the slide rail 82 can be controlled. The transmission member 89 is a structure that can be driven and matched with a transmission belt, or a structure that is matched with a gear and a toothed belt.

[0053] In addition, the support frame 81 is provided with a support arm 85, and the support arm 85 is provided with a staggered material moving mechanism 86 arranged below the discharging station 84. The staggered material moving mechanism 86 is used to move the flat tumbler (24) and the tumbler (23) to be arranged above and below to form a first assembly, and to move the aluminum ball (26) and the spring (25) to be arranged above and below to form a second assembly. The staggered material moving mechanism 86 cooperates with the discharging station 84 to first discharge the tumbler 23, the flat tumbler 24, the spring 25 and the aluminum ball 26 through the discharging station 84, and then move the flat tumbler 24 to be directly above the tumbler 23 to form the first assembly, and move the aluminum ball 26 to be directly above the spring 25 to form the second assembly by operating the staggered material moving mechanism 86. In this way, the staggered displacement is realized, which facilitates the subsequent one-time loading into each tumbler groove 22 of the tumbler lock and improves the assembly efficiency of the tumbler lock. The specific staggered displacement will be described below.

[0054] The support frame 81 is also provided with a material conveying component 810 arranged below the staggered material moving mechanism 86 and used for conveying the first assembly (i.e., the flat spring 24 and the marble 23 arranged in an up-down manner) and the second assembly (i.e., the aluminum ball 26 and the spring 25 arranged in an up-down manner) to a designated mounting position; after the flat spring 24 is moved to the upper side of the marble 23 and the aluminum ball 26 is moved to the upper side of the spring 25 by the staggered material moving mechanism 86, the flat spring 24 and the marble 23 arranged in an up-down manner and the aluminum ball 26 and the spring 25 arranged in an up-down manner are dropped into the material conveying component 810, and then the material conveying component 810 is operated to convey the flat spring 24 and the marble 23 arranged in an up-down manner and the aluminum ball 26 and the spring 25 arranged in an up-down manner to the designated mounting position, and then the aluminum ball 26 and the spring 25 arranged in an up-down manner are staggered to the upper side of the flat spring 24 and the marble 23 arranged in an up-down manner, so that the marble 23, the flat spring 24, the spring 25 and the aluminum ball 26 are arranged in a sequence from bottom to top and are aligned with the cartridge 22 of the marble lock, and the marble 23, the flat spring 24, the spring 25 and the aluminum ball 26 are loaded into the designated cartridge 22 at one time; under the cooperation of the above mechanisms, the components of the marble lock are conveyed, staggered and then conveyed to the designated position for automatic mounting, the whole process is automatically set, no additional operation of the staff is needed, and the assembly efficiency of the marble lock is greatly improved.

[0055] As shown in Figures 5-7 The blanking station 84 includes a guide plate 841 arranged in an upright posture and a support block 842 arranged on the top of the guide plate 841, the guide plate 841 is formed with a flat spring conveying passage 843 arranged vertically and used for conveying the flat spring 24, and the support block 842 is provided with a first conveying component used for conveying the flat spring 24 into the flat spring conveying passage 843 one by one and continuously. In use, the first conveying component is controlled to drive a single flat spring 24 to move to be aligned with the flat spring conveying passage 843, and then the flat spring 24 in the first conveying component is automatically dropped into the flat spring conveying passage 843 and conveyed through the flat spring conveying passage 843 to realize continuous blanking and conveying of the flat spring 24.

[0056] The first conveying component comprises a flat spring conveying pipe 844 arranged on the support block 842, which is vertically arranged and used for continuously providing the flat spring 24 from top to bottom, and is connected with a peripheral vibration disc (not shown in the figure) loaded with the flat spring 24. In use, the vibration disc loaded with the flat spring 24 is operated to convey the flat spring 24 into the flat spring conveying pipe 844 one by one through directional vibration, and then the flat spring 24 is guided through the flat spring conveying pipe 844 to be orderly conveyed from top to bottom. The first conveying component further comprises a first sliding groove 845 formed in the support block 842 and arranged transversely, and the top end of the flat spring conveying channel 843 is arranged in communication with the first sliding groove 845. A first conveying member 847 for conveying a single flat spring 24 is slidably arranged in the first sliding groove 845 to convey the flat spring 24 conveyed by the flat spring conveying pipe 844 into the flat spring conveying channel 843, and the first conveying member 847 is formed with a first placing hole 848 for loading a single flat spring 24, and the depth of the first placing hole 848 is consistent with the length of the flat spring 24.

[0057] When the first conveying member 847 is placed in the initial position, the first placing hole 848 on the first conveying member 847 is arranged directly below the flat spring conveying pipe 844, and the lowermost flat spring 24 in the flat spring conveying pipe 844 automatically falls into the first placing hole 848. At this time, the first conveying member 847 is controlled to slide transversely in the first sliding groove 845 to drive the single flat spring 24 to move (the next flat spring 24 to be conveyed is blocked by the first conveying member 847), and after moving to be arranged directly above the flat spring conveying channel 843, the flat spring 24 in the first placing hole 848 automatically falls into the flat spring conveying channel 843 for conveying. Through the reciprocating sliding of the first conveying member 847 in the first sliding groove 845, the single flat spring 24 is continuously conveyed and discharged, and then conveyed to the next mechanism through the flat spring conveying channel 843 for subsequent assembly of the pin tumbler lock.

[0058] The blanking station 84 is used for continuously blanking and conveying the flat bullets 24. In order to continuously convey and blank the bullets 23 of different lengths, the bullet conveying channel 849 for conveying the bullets 23 is formed in the guide plate 841 and arranged vertically. A plurality of first guide channels 8410 are also formed in the guide plate 841 and arranged obliquely, and the ends of the first guide channels 8410 are communicated with the bullet conveying channel 849. The first guide channels 8410 are used for guiding the bullets 23 into the bullet conveying channel 849. The bullet conveying channel 849 is arranged side by side with the flat bullet conveying channel 843. A plurality of second conveying components are arranged on the support block 842 and used for conveying the bullets 23 into the corresponding first guide channels 8410 one by one and continuously. The number of the second conveying components is consistent with the number of the first guide channels 8410, and each second conveying component is used for conveying the bullets 23 of different lengths. Each second conveying component is arranged in communication with the initial end of the different first guide channels 8410. Since the lengths of the bullets 23 in the bullet lock are different, the second conveying components are arranged for conveying the bullets 23, and the second conveying components are corresponded with the different first guide channels 8410, respectively. Thus, the bullets 23 of different lengths are conveyed into the different first guide channels 8410, respectively, guided by the first guide channels 8410, and finally conveyed to the next mechanism through the bullet conveying channel 849. Thus, the automatic blanking of the bullets 23 is realized, and the subsequent assembly of the bullet lock is facilitated.

[0059] Further, the second conveying component includes the second chute 8412 formed in the support block 842 and arranged transversely. The top ends of the first guide channels 8410 are communicated with the second chutes 8412 one by one.

In addition, each second conveying part is controlled separately. After the teeth of the key are detected (the height of the teeth is detected), the order of operation of the second conveying part is controlled according to the detected data, so that the pin tumbler lock processed subsequently can be matched with the key. The specific detection method is the prior art, which is not described here.

[0061] In this embodiment, the thicknesses of the second material conveying parts 8414 are different (as shown in Figure 3 The depth of the second placing hole 8415 is basically the same as the length of the pin 23 to be conveyed, so that pins 23 of different lengths can be conveyed.

[0062] In order to realize continuous conveying and discharging of the aluminum ball 26, the guide plate 841 is formed with an aluminum ball conveying channel 8419 arranged vertically and used for conveying the aluminum ball 26, and the guide plate 841 is further provided with a third conveying part used for conveying the aluminum ball 26 into the aluminum ball conveying channel 8419 one by one and continuously; the third conveying part is controlled to operate to drive the single aluminum ball 26 to move, and after the aluminum ball 26 in the third conveying part is moved to be aligned with the aluminum ball conveying channel 8419, the aluminum ball 26 automatically falls into the aluminum ball conveying channel 8419 and is conveyed through the aluminum ball conveying channel 8419 to realize continuous discharging and conveying of the aluminum ball 26.

[0063] As Figure 8As shown, the third conveying component includes an aluminum ball conveying pipe 8420 arranged on the top of the guide plate 841, the aluminum ball conveying pipe 8420 is vertically arranged and used for continuously providing the aluminum balls 26 from top to bottom, the aluminum ball conveying pipe 8420 is connected with a vibrating disc (not shown in the figure) loaded with the aluminum balls 26; the third conveying component further includes a third chute 8421 shaped in the guide plate 841 and arranged transversely, the top end of the aluminum ball conveying channel 8419 is arranged in communication with the third chute 8421; a third conveying piece 8422 for conveying a single aluminum ball 26 is slidingly arranged in the third chute 8421, so as to convey the aluminum balls 26 conveyed by the aluminum ball conveying pipe 8420 into the aluminum ball conveying channel 8419, the third conveying piece 8422 is shaped with a third placing hole 8423 for loading a single aluminum ball 26, the depth of the third placing hole 8423 is consistent with the size of the aluminum ball 26.

[0064] When the third conveying piece 8422 is placed in the initial position, the third placing hole 8423 on the third conveying piece 8422 is placed directly below the aluminum ball conveying pipe 8420, the aluminum ball 26 placed at the lowermost position in the aluminum ball conveying pipe 8420 automatically falls into the third placing hole 8423, at this time, the third conveying piece 8422 is controlled to slide transversely in the third chute 8421, so as to drive the single aluminum ball 26 to move (the next aluminum ball 26 to be conveyed is blocked by the third conveying piece 8422), after moving to be placed directly above the aluminum ball conveying channel 8419, the aluminum ball 26 in the third placing hole 8423 automatically falls into the aluminum ball conveying channel 8419 for conveying, by controlling the third conveying piece 8422 to slide reciprocally in the third chute 8421, the single aluminum ball 26 is continuously conveyed and discharged, and conveyed to the next mechanism through the aluminum ball conveying channel 8419, so as to facilitate the subsequent assembly of the pin tumbler lock.

[0065] In order to realize the continuous conveying and discharging process of the spring 25, the guide plate 841 is shaped with a spring conveying channel 8424 arranged vertically and used for conveying the spring 25, and the guide plate 841 is further arranged with an intermittent discharging component for controlling the spring 25 to fall into the spring conveying channel 8424 for conveying one by one; the intermittent discharging component is controlled, so that the single spring 25 falls into the spring conveying channel 8424, thereby conveying the spring 25 through the spring conveying channel 8424, when the intermittent discharging component continuously discharges, the spring 25 is continuously discharged and conveyed.

[0066] As Figure 9As shown, the intermittent discharging component comprises a spring conveying pipe 8425 arranged on the top of the guide plate 841, which is vertically arranged and used for continuously providing the springs 25 from top to bottom, and is connected with a vibration disc (not shown in the figure) loaded with the springs 25; the intermittent discharging component further comprises a movable element 8426 transversely and slidably arranged on the guide plate 841, which is provided with a blocking rod 8427 transversely arranged and used for blocking the springs 25 into the spring conveying channel 8424, and is further provided with a pushing rod 8428 transversely and slidably arranged and staggered with the blocking rod 8427; when the blocking rod 8427 blocks the first spring 25 arranged from bottom to top, the pushing rod 8428 does not contact the spring 25; when the movable element 8426 is transversely moved to make the blocking rod 8427 not block the spring 25, the pushing rod 8428 applies a transverse pushing force to the second spring 25 arranged from bottom to top, so that the second spring 25 arranged from bottom to top is placed into the spring conveying channel 8424, while the first spring 25 arranged from bottom to top automatically falls downward without being blocked by the pushing rod 8428, and is guided and conveyed through the spring conveying channel 8424; at this time, the movable element 8426 is controlled to be transversely reset, the blocking rod 8427 blocks the spring conveying channel 8424 again, and the pushing rod 8428 stops applying force to the spring 25, then all the springs 25 automatically fall by one spring 25, and are blocked by the blocking rod 8427, so that the second spring 25 originally arranged from bottom to top becomes the first spring 25 arranged from bottom to top; by controlling the movable element 8426 to reciprocatingly and transversely move on the guide plate 841, the intermittent discharging of the springs 25 is realized.

A first elastic member 8431 is arranged in the sliding chamber 8429 and is used to apply a pushing force to the third sliding block 8430. The pushing direction of the first elastic member 8431 is towards the push rod 8428. When the movable member 8426 is controlled to slide on the guide plate 841 towards the spring conveying channel 8424, the end of the push rod 8428 away from the third sliding block 8430 first contacts the side of the second spring 25 arranged from bottom to top, and then the movable member 8426 is continuously controlled to slide, the push rod 8428 stops moving, the first elastic member 8431 is compressed, and a pushing force is applied to the push rod 8428, so that the second spring 25 arranged from bottom to top is stably arranged in the spring conveying channel 8424 and cannot fall down. When the movable member 8426 slides to the position where the blocking rod 8427 does not block the first spring 25 arranged from bottom to top, the spring 25 automatically falls down, and then the movable member 8426 is controlled to be laterally reset, the blocking rod 8427 blocks the spring conveying channel 8424 again, the compressed first elastic member 8431 is reset, the pushing force applied to the push rod 8428 and the spring 25 is removed, the spring 25 automatically falls down and is blocked by the blocking rod 8427, and the subsequent automatic material falling is facilitated.

[0078] As Figures 13-14As shown, the material conveying component 810 comprises a mounting plate 8101 mounted on the support frame 81, the mounting plate 8101 is slidably provided with a movable plate 8102 in the same sliding direction as the sliding direction of the adjusting plate 83, the movable plate 8102 is mounted with a material conveying block 8103, the material conveying block 8103 is formed with a mounting cavity 8107, the mounting cavity 8107 is provided with a first movable block 8104 and a second movable block 8105 which can slide towards each other or away from each other, the first movable block 8104 and the second movable block 8105 are symmetrically arranged and the sliding direction is perpendicular to the sliding direction of the movable plate 8102, the side of the first movable block 8104 and the second movable block 8105 facing each other is formed with an arc-shaped groove 8106, the arc-shaped groove 8106 on the first movable block 8104 and the arc-shaped groove 8106 on the second movable block 8105 surround to form a component channel, the component channel is provided with a plurality of component channels for storing the first assembly (i.e. the horizontally arranged flat spring 24 and the marble 23), the top end of the plurality of component channels is respectively communicated with the bottom end of different second material guiding channels 8619. A material moving block 81010 is slidably arranged on the top of the material conveying block 8103, the sliding direction of the material moving block 81010 is consistent with the sliding direction of the first movable block 8104 (or the second movable block 8105), the material moving block 81010 is formed with a plurality of storage cavities 81011 for storing the second assembly (i.e. the vertically arranged aluminum ball 26 and the spring 25), the material conveying block 8103 is laterally slid to drive the second assembly in each storage cavity 81011 to be aligned with different component channels. When the material conveying block 8103 is laterally slid to the bottom end of each storage cavity 81011 and is respectively communicated with the top end of different component channels, the second assembly and the first assembly are vertically arranged, the staggered displacement of the second assembly and the first assembly is completed, and the marble 23, the flat spring 24, the spring 25 and the aluminum ball 26 are sequentially arranged from bottom to top, which can be loaded into the corresponding cartridge 22 at one time.
