Description

Technical Field

[0001] The utility model relates to the field of leaf lock processing, in particular to a leaf assembling machine and a leaf material selecting device thereof. Background Art

[0002] Traditional leaf locks generally consist of a lock core and a housing provided with a rolling pin locking mechanism. The lock core with the rolling pin locking mechanism is composed of leaves, rolling pins and a lock core sleeve. The leaves can rotate a certain angle within the lock core sleeve. Each leaf is provided with rolling pin grooves at different angles, and a sliding groove for placing the rolling pins is provided on the side wall of the lock core sleeve. When unlocking, through the contact between the tooth profile groove of the key and the key insertion hole in the middle of the leaf, when the leaf is rotated to the designed position, the rolling pin grooves on all the leaves are in the same straight line, and the rolling pins fall into the rolling pin grooves of the leaves, enabling the lock core sleeve to rotate relative to the housing to unlock; when locking, the key is rotated to misalign the rolling pin grooves on the leaves, the rolling pins are ejected from the rolling pin grooves, and locking with the housing is achieved.

[0003] Refer to the attached Figure 2 leaf shape shown in the Chinese utility model patent with the publication number of "CN202152576U", and the attached Figure 4 existing ordinary circular leaf shape shown in the Chinese invention patent text with the publication number of "CN208251860U". Also refer to the existing circular leaf shape shown in the Chinese design patent with the publication number of "CN302887108S". Generally speaking, the middle part of the existing leaf body shown in the above documents is provided with a key hole for the key to pass through, and protrusions and rolling pin grooves are provided on the circular outer edge of the leaf body. During the assembly process of the leaves with the above structure, the leaves must be inserted into the lock core sleeve of the leaf lock in sequence according to the tooth profile of the key in a regular direction; however, since the leaves need to be vibrated and polished by a vibrating disk and electroplated after being punched by a punching machine, they are in a chaotic state when it comes to assembly and use. Due to the design of the original leaves, it is very difficult for automated equipment to arrange them in a specified order, which becomes a technical bottleneck for the automated assembly of leaf locks.

[0004] This solution aims to optimize and improve the material selection and arrangement of existing leaves. Summary of the Invention

[0005] In order to solve the above problems, the first object of the utility model is to provide a leaf material selecting device, which can automatically select and arrange materials for existing leaves, thereby improving the leaf arrangement efficiency.

[0006] In order to achieve the above object, the utility model adopts the following technical solutions:

[0007] A blade material selection device includes a material selection base, a stringing rod for arranging and stringing blades in a specified direction, and a material selection component capable of planar movement and lifting; characterized in that: a material selection port and an induction component are provided on the material selection base, and the induction end of the induction component is arranged on the circumferential side wall of the material selection port; the material selection component includes a plugging rod rotatably arranged. After the material selection component descends until the lower end of the plugging rod is adaptively plugged into the central hole of the blade, during the rotation of the plugging rod driving the blade, the convex block on the outer edge of the blade triggers the induction end of the induction component; the material selection component holds and transfers the blade to the waste area or the stringing rod based on whether the angle of the detection axis of the plugging rod relative to the reference line meets a preset angle value when triggered.

[0008] The present utility model adopts the above technical solution, which relates to a blade material selection device. The material selection base in the blade material selection device is used to feed and place the blades to be selected, and the material selection component is used to screen the blades, so as to place the blades on the stringing rod in a set manner, enabling the blades to be arranged and strung in a specified direction on the stringing rod.

[0009] Specifically, in this solution, the blade is conveyed or placed into the material selection port. After the lower end of the plugging rod in the material selection component is adaptively plugged into the central hole of the blade, it can drive the blade to rotate synchronously. During the rotation, when the convex block on the outer edge of the blade passes through the induction end of the induction component, it will trigger the induction. At this time, by judging whether the angle of the detection axis of the plugging rod relative to the reference line meets the preset angle value, relevant information such as whether the front and back orientations of the blade are correct can be judged. Specifically, the following steps can be executed:

[0010] 1. When the convex block on the outer edge of the blade triggers the induction and the detection axis of the plugging rod meets the preset angle value with the reference line, it is judged that the front and back orientations of the blade are correct, and the material selection component holds and transfers the blade to the stringing rod;

[0011] 2. When the convex block on the outer edge of the blade triggers the induction and the detection axis of the plugging rod does not meet the preset angle value with the reference line, and the front and back orientations of the blade are incorrect, the material selection component holds and transfers the blade to the waste area.

[0012] Based on the above blade material selection device, automatic material selection and discharging of existing blades can be carried out, thereby improving the blade arrangement efficiency.

[0013] In a specific implementation, a feeding track and a pushing rod for pushing along the feeding track are provided on the material selection base; the material selection port is at the end of the feeding track, and the pushing rod is used to push the blade in the feeding track to the material selection port. This solution uses the feeding track to introduce the blade. The feeding track can be connected to the output track of the vibrating disk, and the pushing rod can push the blade to the material selection port.

[0014] In a specific embodiment, the sensing assembly includes a sensing rod and an elastic member acting on the sensing rod; the elastic member acts on the sensing rod to make the sensing end inside it protrude from the circumferential side wall of the material selection port; when the bump on the outer edge of the blade triggers the sensing end of the sensing assembly, it pushes the sensing rod to move axially. In this solution, the sensing end at the inner end of the sensing rod protrudes from the circumferential side wall of the material selection port, and the axial direction of the sensing rod is the radial direction of the material selection port. When the material selection assembly drives the blade to rotate, the bump on the outer edge of the blade can push the sensing rod to move axially to generate an axial displacement, which can be detected by a sensor.

[0015] In a further solution, the elastic member is a compression spring, and the compression spring is sleeved outside the sensing rod and its deformed end abuts against the sensing rod. In this solution, the compression spring drives the sensing rod to reset, and when the bump on the outer edge of the blade pushes the sensing rod outwards, the compression spring produces a certain amount of compression.

[0016] In one of the embodiments, the material selection assembly further includes a blanking sleeve sleeved outside the insertion rod and capable of lifting relative to it; during blanking, the blanking sleeve is used to push the blade inserted on the insertion rod down. In this solution, the insertion rod can position and fix the blade when inserted into the central hole of the blade, and during blanking, the blade needs to be removed from the insertion rod by the downward movement of the blanking sleeve.

[0017] Further, a groove or a through hole is formed on the lower end portion of the insertion rod, and an elastic snap spring is embedded in the groove; at least part of the elastic snap spring protrudes from the groove or the through hole for elastically clamping the central hole of the blade. Thus, when the insertion rod is inserted into the central hole of the blade, the inner wall of the central hole of the blade presses the elastic snap spring, so that the blade is clamped on the insertion rod.

[0018] When the blanking sleeve moves downward to remove the blade from the insertion rod, the elastic snap spring resets.

[0019] The part of the elastic snap spring protruding from the groove or the through hole is constructed as an arc, which is convenient for inserting and withdrawing from the central hole of the blade.

[0020] In another embodiment, the material selection assembly further includes an adsorption member sleeved outside the insertion rod for adsorbing the end face of the blade. In this solution, when the insertion rod is inserted into the central hole of the blade, the end face of the blade is adsorbed by the adsorption member on the outside, so that the blade can be clamped and positioned.

[0021] In a specific solution, the adsorption member is constructed as an electromagnet or a negative pressure suction cup.

[0022] The second object of the present utility model is to provide a blade assembling machine, including the above-mentioned blade material selection device. Description of the Drawings

Embodiment 1

[0032] As Figures 2 to 4 shown, this embodiment relates to a blade material selection device, which includes a material selection base 1, a stringing rod 2 for arranging and stringing blades 10 in a specified direction, and a material selection component 3 capable of planar movement and lifting. In a specific implementation, a feeding track 11 and a pushing rod 12 for pushing along the feeding track 11 are provided on the material selection base 1.

[0033] As Figure 4 shown, a material selection port 13 and an induction component 4 are provided on the material selection base 1. The material selection port 13 is located at the end of the feeding track 11, and the pushing rod 12 is used to push the blade 10 in the feeding track 11 to the material selection port 13. In this solution, the feeding track 11 is used to introduce the blade 10, and the feeding track 11 can be connected to the output track of the vibrating disk, and the pushing rod 12 can push the blade 10 to the material selection port 13.

[0034] The induction end of the induction component 4 is arranged on the circumferential side wall of the material selection port 13. Specifically, the induction component 4 includes an induction rod 41 and an elastic component 42 acting on the induction rod 41. The elastic component 42 acts on the induction rod 41 to make the induction end inside it extend out of the circumferential side wall of the material selection port 13. When the convex block on the outer edge of the blade 10 triggers the induction end of the induction component 4, it pushes the induction rod 41 to move axially. In this solution, the induction end at the inner end of the induction rod 41 extends out of the circumferential side wall of the material selection port 13, and the axial direction of the induction rod 41 is the radial direction of the material selection port 13. When the material selection component 3 drives the blade 10 to rotate, the convex block on the outer edge of the blade 10 can push the induction rod 41 to move axially to generate an axial displacement, which can be detected by a sensor. In a further solution, the elastic component 42 is a compression spring, and the compression spring is sleeved outside the induction rod 41 and its deformation end abuts against the induction rod 41. In this solution, the compression spring drives the induction rod 41 to reset, and when the convex block on the outer edge of the blade 10 pushes the induction rod 41 outwards, the compression spring produces a certain amount of compression.

[0035] As Figure 2 and 3As shown, the material selection component 3 includes a plugging rod 31 rotatably arranged. After the material selection component 3 moves downward until the lower end of the plugging rod 31 is adaptively plugged into the central hole 100 of the blade, during the process of the plugging rod 31 driving the blade 10 to rotate, the bump on the outer edge of the blade 10 triggers the sensing end of the sensing component 4. Based on whether the angle of the detection axis of the plugging rod 31 relative to the reference line meets the preset angle value when triggered, the material selection component 3 clamps the blade 10 and transfers it to the waste area or transfers it onto the stringing rod 2. The material selection base 1 in this blade material selection device is used to feed and place the blades 10 to be selected, and the material selection component 3 is used to screen the blades 10, so as to place the blades 10 on the stringing rod 2 in a set manner, enabling the blades 10 to be strung along the specified direction on the stringing rod 2.

[0036] In Figure 3 In one of the embodiments shown, the material selection component 3 further includes a blanking sleeve 32 sleeved outside the plugging rod 31 and capable of moving up and down relative to it. During blanking, the blanking sleeve 32 is used to push down the blade 10 plugged on the plugging rod 31. In this solution, when the plugging rod 31 is plugged into the central hole 100 of the blade, it can position and fix the blade 10, and when blanking, it is necessary to move the blanking sleeve 32 downward to remove the blade 10 from the plugging rod 31. Further, a groove 311 or a through hole is formed on the lower end portion of the plugging rod 31, and an elastic snap spring 33 is embedded in the groove 311. At least part of the elastic snap spring 33 extends out of the groove 311 or the through hole for elastically clamping the central hole 100 of the blade. Thus, when the plugging rod 31 is inserted into the central hole 100 of the blade, the inner wall of the central hole 100 of the blade presses the elastic snap spring 33, so that the blade 10 is clamped on the plugging rod 31. When the blanking sleeve 32 moves downward to remove the blade 10 from the plugging rod 31, the elastic snap spring 33 resets. The part of the elastic snap spring 33 extending out of the groove 311 or the through hole is constructed as an arc, which is convenient for inserting into and withdrawing from the central hole 100 of the blade.

[0037] In another embodiment, the material selection component 3 further includes an adsorption component sleeved outside the plugging rod 31 for adsorbing the end face of the blade 10. In this solution, when the plugging rod 31 is inserted into the central hole 100 of the blade, the end face of the blade 10 is adsorbed by the adsorption component on the outside, so as to clamp and position the blade 10. In a specific solution, the adsorption component is constructed as an electromagnet or a negative pressure suction cup.

[0038] When the above solution is implemented, the blade 10 in this solution is conveyed or placed into the material selection port 13. The material selection assembly 3 descends until the lower end of the insertion rod 31 presses against the blade 10. During rotation, the center hole 100 of the blade is searched for until the lower end of the insertion rod 31 is aligned with the center hole 100 of the blade and then quickly inserted. Then, the blade 10 can be driven to rotate synchronously. During rotation, when the convex block on the outer edge of the blade 10 passes through the sensing end of the sensing assembly 4, the sensing will be triggered. At this time, by determining whether the angle between the detection axis of the insertion rod 31 and the reference line meets the preset angle value, relevant information such as whether the front and back orientations of the blade 10 are correct can be determined. And based on the above conditions, the following steps can be executed:

[0039] 1. When the convex block on the outer edge of the blade triggers the sensing and the angle between the detection axis of the insertion rod and the reference line meets the preset angle value, it is determined that the front and back orientations of the blade are correct, and the material selection assembly clamps the blade and transfers it to the stringing rod;

[0040] 2. When the convex block on the outer edge of the blade triggers the sensing and the angle between the detection axis of the insertion rod and the reference line does not meet the preset angle value and the front and back orientations of the blade are incorrect, the material selection assembly clamps the blade and transfers it to the waste area.

[0041] Based on the above blade material selection device, automatic material selection and discharging of the existing blade 10 can be carried out, thereby improving the arrangement efficiency of the blade 10.

[0042] For example, since there are four arrangement situations for the vertical and horizontal central axes of the blade to be perpendicular; when the blade rotates to the trigger sensing state through the insertion rod 31, there are four states, such as Figure 1a 、 1b 、1c and 1d shown;

[0043] Such as Figure 1a and Figure 1d shown, the back of the blade 10 is facing up; among them, in the solution such as Figure 1a , when the sensing is triggered, the angle between the detection axis of the insertion rod 31 and the reference line is 90°; in the solution such as Figure 1d , when the sensing is triggered, the angle between the detection axis of the insertion rod 31 and the reference line is 270°.

[0044] Such as Figure 1b and Figure 1c shown, the front of the blade 10 is facing up; among them, in the solution such as Figure 1b , when the sensing is triggered, the detection axis of the insertion rod 31 coincides with the reference line and the angle is 0°; in the solution such as Figure 1c , when the sensing is triggered, the angle between the detection axis of the insertion rod 31 and the reference line is 180°.

[0045] If the direction of the arranged blade 10 of the device is with the front side facing up, then when determining whether the angle between the detection axis of the insertion rod 31 and the reference line meets the preset angle value, it is to determine whether the angle between the detection axis of the insertion rod 31 and the reference line is 0° or 180°. And based on the above conditions, the following steps can be executed:

[0046] 1. When it is determined that the angle between the detection axis of the insertion rod 31 and the reference line is 0° and 180°, it is considered that the front and back sides of the blade 10 are facing correctly, and the material selection component 3 clamps the blade 10 and transfers it to the stringing rod 2.

[0047] 2. When it is determined that the angle between the detection axis of the insertion rod 31 and the reference line is 90° and 270°, it is considered that the above requirements are not met and the front and back sides of the blade 10 are facing incorrectly. Then the material selection component 3 clamps the blade 10 and transfers it to the waste area. Embodiment 2
