Abstract
Description
Technical Field
[0001] This utility model relates to the field of marking machine technology, and in particular to an automatic key recognition marking machine. Background Technology
[0002] Laser marking can engrave various patterns, texts, numbers, etc. on keys to achieve the purpose of identification and anti-counterfeiting. Through laser engraving, counterfeiting and duplication can be prevented, increasing the security and recognizability of the keys.
[0003] Currently, after keys are produced, one method is to classify and place the various types of keys before transferring them to a laser marking machine for laser marking. When keys are manually placed, it is easy to forget to control and adjust the laser marking machine when different types of keys need to be marked, resulting in marking errors. Another method is to immediately transfer each type of key to the laser marking machine for marking. While this avoids marking errors, the high frequency of transfers wastes a lot of time and leads to low processing efficiency. In addition, both existing laser marking methods require manual control and adjustment of the laser marking machine to mark different types of keys, which is not only cumbersome but also prone to errors during manual control and adjustment. Utility Model Content
[0004] In order to overcome the shortcomings of the existing technology, this utility model provides an automatic key recognition and marking machine to solve the problem that the two existing laser marking methods both require manual control and debugging of the laser marking machine to mark different types of keys, which is not only troublesome, but also prone to errors during manual control and debugging.
[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an automatic key recognition and marking machine, wherein at least one side of the key has a toothed groove, and the automatic recognition and marking machine includes:
[0006] Turntable;
[0007] At least one fixing block, the fixing block being located on a turntable, the fixing block being provided with a limiting structure for limiting and fixing the key;
[0008] The identification mechanism includes a first lifting component, a movable block, a contact switch, and a probe. The bottom of the movable block has several movable holes, and several probes are slidably disposed inside the movable holes. A contact switch is provided on the top surface of the inner wall of each movable hole. The distance between the probe and the contact switch is not greater than the depth of the tooth groove. When the fixed block is facing the identification mechanism, the key is located directly below the probe. The first lifting component is used to drive the probe to move closer to or away from the key on the fixed block.
[0009] The marking mechanism includes a laser marking machine;
[0010] The controller, each of the contact switches is signal-connected to the controller, and the controller is signal-connected to the laser marking machine;
[0011] When the turntable rotates, the fixing block is positioned directly below the probe and the laser marking machine in sequence.
[0012] Preferably, there are four fixed blocks, each of which is equidistantly arranged on the turntable. The automatic identification marking machine also includes a steel stamping mechanism, which includes a second lifting component and a steel stamping head. The second lifting component is used to drive the steel stamping head to move closer to or away from the key on the fixed block. When one of the fixed blocks is located directly below the probe, the steel stamping head and the laser marking machine are respectively located directly above one of the fixed blocks.
[0013] Preferably, a limiting groove is formed on the inner sidewall of the movable hole, and a limiting block is provided on the outer wall of the probe, the limiting block being slidably disposed in the limiting groove.
[0014] Preferably, an elastic element is fixed between the top or bottom surface of the inner wall of the limiting groove and the limiting block.
[0015] Preferably, the limiting structure is a fixing groove that is adapted to the key.
[0016] Preferably, the second lifting assembly includes a second cylinder and a second movable plate, and the stamping head is detachably fixed to the second movable plate.
[0017] Preferably, the top of the stamp head is provided with a threaded post, and the second movable plate is provided with a threaded hole adapted to the threaded post.
[0018] Compared with the prior art, the beneficial effects that this utility model can achieve are:
[0019] The key is placed on a fixed block and fixed by a limiting structure. The turntable is rotated to align the probe with the key. The first lifting component is then adjusted to move the probe downwards closer to the key. When some probes first contact the key surface, and then others enter the tooth groove, the probes in contact with the key surface move upwards relative to the movable hole until the tip of that part of the probe contacts the contact switch. Pressing the switch triggers the corresponding contact switch, which sends a signal to the controller. The first lifting component is then adjusted to move the probes upwards and reset. The turntable then rotates, moving the key directly below the laser marking machine. The controller then controls the laser marking machine to mark the corresponding mark on the key, thus completing the automatic identification and marking of the key. This avoids the hassle of manually controlling and adjusting the laser marking machine to mark different types of keys with different marks, and also avoids errors or forgotten adjustments during manual control and adjustment, improving the marking efficiency and accuracy of the key.

[0026] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model is further described below in conjunction with specific embodiments. However, the following embodiments are only preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments in the implementation methods without creative effort are all within the protection scope of this utility model.
[0027] like Figures 1-4 As shown, this utility model provides an automatic key recognition and marking machine. The key 6 has a toothed groove 61 on at least one side. The automatic recognition and marking machine includes: a turntable 1, at least one fixed block 2, a recognition mechanism 3, a marking mechanism 4, and a controller.
[0028] The fixing block 2 is located on the turntable 1, and the fixing block 2 is provided with a limiting structure for limiting and fixing the key 6;
[0029] The identification mechanism 3 includes a first lifting component, a movable block 34, a contact switch, and a probe 35. The bottom of the movable block 34 has several movable holes 341. Several probes 35 are slidably arranged inside the movable holes 341. The top surface of the inner wall of each movable hole 341 is provided with a contact switch (not shown in the figure). The distance between the probe 35 and the contact switch is not greater than the depth of the tooth groove 61. When the fixed block 2 is facing the identification mechanism 3, the key 6 is located directly below the probe 35. The first lifting component is used to drive the probe 35 to move closer to or away from the key 6 on the fixed block 2.
[0030] By setting the distance between the probe 35 and the contact switch to be no greater than the depth of the groove 61, it is ensured that during the continuous downward movement of the probe 35, a portion of the probe 35 first contacts the surface of the key 6, and then when another portion of the probe 35 enters the groove 61, the probe 35 that contacts the surface of the key 6 will move upward relative to the movable hole 341 until the top of this portion of the probe 35 contacts the contact switch, and pressing triggers the corresponding contact switch. Before the probe 35 contacts the key 6, each probe 35 does not contact each contact switch.
[0031] The first lifting assembly here includes a first vertical plate 31, a first cylinder 32 and a first movable plate 33. The first cylinder 32 is fixedly installed on the first vertical plate 31, the output end of the first cylinder 32 is fixedly connected to the first movable plate 33, and the movable block 34 is fixedly installed on the first movable plate 33.
[0032] The marking mechanism 4 includes a support frame 41 and a laser marking machine 42, with the laser marking machine 42 fixed on the support frame 41;
[0033] Each contact switch is connected to the controller (not shown in the figure), and the controller is connected to the laser marking machine 42.
[0034] When the turntable 1 rotates (the turntable 1 can be driven to rotate by a motor), the fixed block 2 is located directly below the probe 35 and the laser marking machine 42 in sequence;
[0035] After key 6 is manufactured, it is placed on fixed block 2 and fixed by limiting structure. At this time, the tooth groove 61 on key 6 faces upward. Adjust turntable 1 to rotate so that key 6 is directly below recognition mechanism 3 and probe 35 is facing key 6. Then adjust the first lifting component to drive movable block 34 to move down. The movement of movable block 34 drives probe 35 to move down and move closer to key 6. During the continuous downward movement of probe 35, when part of probe 35 first contacts the surface of key 6 and then another part of probe 35 enters the tooth groove 61, the probe 35 in contact with the surface of key 6 will move upward relative to movable hole 341 until the top of that part of probe 35 contacts the contact switch. When the probe 35 inside the toothed groove 61 is pressed (without contacting the toothed groove 61), the corresponding contact switch is triggered. The contact switch sends a signal to the controller, which then adjusts the first lifting component to move the probe 35 upward and reset it. After that, the turntable 1 rotates, causing the key 6 to move directly below the laser marking machine 42. The controller then controls the laser marking machine 42 to mark the corresponding mark on the key 6, thus completing the automatic identification and marking of the key 6. This avoids the trouble of manually controlling and adjusting the laser marking machine 42 to mark different types of keys 6 with different marks, and also avoids possible errors or forgotten adjustments during manual control and adjustment, thus improving the marking efficiency and accuracy of the key 6.
[0036] It should be noted that the principle by which the controller controls the laser marking machine 42 to subsequently print the corresponding mark after the corresponding contact switch is triggered can be controlled by the program setting, which will not be elaborated here.
[0037] like Figures 1-5 As shown, there are four fixed blocks 2, and each fixed block 2 is equidistantly arranged on the turntable 1. The automatic identification marking machine also includes a steel stamping mechanism 5, which includes a second lifting component and a steel stamping head 54. The second lifting component is used to drive the steel stamping head 54 to move closer to or further away from the key 6 on the fixed block 2. When a fixed block 2 is located directly below the probe 35, the steel stamping head 54 and the laser marking machine 42 are respectively located directly above a fixed block 2.
[0038] The second lifting assembly here includes a second vertical plate 51, a second cylinder 52, and a second movable plate 53. The second cylinder 52 is fixedly installed on the second vertical plate 51, and the output end of the second cylinder 52 is fixedly installed on the second movable plate 53. The stamping head 54 is located on the second movable plate 53. When the key 6 moves directly below the stamping head 54, the stamping head 54 is driven to move down by adjusting the second lifting assembly to complete the stamping of the key 6, which further facilitates internal employees to package and distinguish different types of keys 6.
[0039] By setting up four fixing blocks 2, after one fixing block 2 feeds the key 6, the keys 6 on the other three fixing blocks 2 can be used for identification, stamping and marking respectively.
[0040] like Figure 3 As shown, a limiting groove (not shown in the figure) is provided on the inner side wall of the movable hole 341, and a limiting block 351 is provided on the outer wall of the probe 35. The limiting block 351 is slidably disposed in the limiting groove.
[0041] By setting the limiting groove and the limiting block 351, it can be ensured that when the key 6 is in contact, the probe 35 is stably placed in the movable hole 341 and will not fall off.
[0042] An elastic element (not shown in the figure) is fixed between the top or bottom surface of the inner wall of the limiting groove and the limiting block 351;
[0043] By setting an elastic element, when the probe 35 contacts the surface of the key 6 during the continuous downward movement of the movable block 34, the probe 35 moves upward relative to the movable block 34. At this time, the elastic element is gradually compressed or stretched. After the subsequent partial contact switch is triggered, the first lifting component drives the movable block 34 to move upward, thereby driving the probe 35 to move upward so that the probe 35 no longer contacts the surface of the key 6. At this time, the elastic element rebounds and returns to its original length, ensuring that the probe 35 can be stably reset. This ensures that the identification mechanism 3 can perform identification work on the subsequent key 6, avoiding the situation where the probe 35 gets stuck in the movable hole 341 when the first lifting component drives the movable block 34 to move upward, and the probe 35 cannot fall along the movable hole 341 due to its own weight.
[0044] like Figure 4 As shown, the limiting structure is a fixing groove 21 that is adapted to the key 6. This ensures the limiting and fixing of the key 6, and facilitates the quick positioning, placement and retrieval of the key 6. At the same time, when the fixing block 2 rotates (here the turntable 1 is driven by the motor to rotate slowly to avoid the centrifugal force causing the key 6 to fall out of the fixing groove 21), the key 6 will not fall out of the fixing groove 21.
[0045] like Figure 5 As shown, the stamp head 54 is detachably fixed to the second movable plate 53, which makes it convenient for people to replace the stamp head 54, so that different stamps can be stamped on different types of keys 6, further facilitating internal employees to package and distinguish different types of keys 6.
[0046] Specifically, the top of the stamp head 54 is provided with a threaded post 55, and the second movable plate 53 is provided with a threaded hole that matches the threaded post 55. It is fixed by screw connection, which facilitates quick disassembly and replacement of the stamp head 54.
[0047] Alternatively, a rotating plate (not shown in the figure) can be rotatably set on the second movable plate 53. Several stamp heads 54 are equidistantly arranged on the rotating plate. In this way, when it is necessary to replace different stamp heads 54, the stamp heads 54 can be switched by adjusting the rotation of the rotating plate, avoiding the trouble of manually disassembling and replacing them repeatedly when a stamp head 54 is fixed by screwing.
[0048] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
