Description

Technical Field

[0001] The utility model relates to the technical field of locks, in particular to a device for detecting the quality of a lock body. Background Technique

[0002] The lock body is one of the important components of a lock. It usually includes lock tongues such as a bevel tongue, a square tongue, and an auxiliary lock tongue. The functions of opening and closing the lock are realized by the expansion and contraction of the above lock tongues, which plays an important role in anti-theft. Therefore, the quality of the lock body will directly affect the overall reliability of the lock. For this reason, manufacturers and inspection departments need to conduct quality inspections on the lock body according to corresponding standards.

[0003] For this reason, in the prior art, there is a lock body detection device disclosed in a Chinese invention application "A Lock Body Quality Detection Device" with a patent number of CN202210350369.X (publication number of CN114813071A). Such lock body detection devices usually use a motor to drive the lock tongue to detect, for example, the handle torque, the number of times the lock tongue returns, etc., and use a cylinder to push the lock tongue to test the pressure value when the lock tongue extends.

[0004] However, such lock body detection devices still have the following defects in actual use: First, the lock body can usually be divided into two types: left version and right version. The two versions are basically symmetrical in appearance, and after the detection is completed, it is necessary to distinguish between the left version and the right version and make corresponding marks. However, the existing lock body detection devices are difficult to automatically distinguish the versions of the lock body; Second, the existing lock body detection devices usually use a cylinder to test the pressure value when the lock tongue extends, and the cylinder is easily affected by air pressure, resulting in inaccurate and ineffective feedback of the pressure value sometimes. Therefore, it is still necessary to further improve the existing lock body detection devices. Summary of the Utility Model

[0005] The first technical problem to be solved by the utility model is to provide a lock body detection device that can automatically identify the left and right versions of the lock body in view of the above-mentioned prior art status.

[0006] The second technical problem to be solved by the utility model is to provide a lock body detection device that can more accurately test the pressure value when the lock tongue extends in view of the above-mentioned prior art status.

[0007] The technical solution adopted by the present utility model to solve the first technical problem is as follows: A lock body detection device includes a clamping mechanism for fixing the lock body. A rotating mechanism is provided on the clamping mechanism and is connected to a rotating shaft hole corresponding to the lock tongue to drive the lock tongue to extend and retract. Correspondingly, a pressing mechanism for pressing and testing the pressure value of the lock tongue is further provided in front of the lock tongue in the extending direction. It is characterized in that: It further includes a visual detection mechanism, and the visual detection mechanism includes an image acquisition module for identifying the left and right layouts of the lock body.

[0008] In order to facilitate the image acquisition module to identify the left and right layouts of the lock body, preferably, the visual detection mechanism further includes a light source adjacent to the lock tongue. The light source is provided for two purposes. On the one hand, it is to facilitate the image acquisition module to effectively use the gray threshold to detect the left and right layouts of the lock body. On the other hand, it can also use the image acquisition module to judge the extending and retracting states of the lock tongue, so as to cooperate with the movement of the pressing mechanism.

[0009] Furthermore, in order to improve the cooperation effect between the image acquisition module and the light source, preferably, the image acquisition module is located on one side of the lock body in the thickness direction, and two light sources are provided, which are respectively arranged on both sides in front of the lock tongue in the extending direction. The image acquisition module is arranged on one side of the lock body in the thickness direction to make the line of sight of the image acquisition module perpendicular to the extending direction of the lock tongue. At the same time, light sources are arranged on both sides in front of the lock tongue in the extending direction, which can more clearly identify the left and right layouts of the lock body by means of the lock tongue.

[0010] For further design, in order to avoid interference from the external environment during the lock body detection process, preferably, it further includes a cover body. A detection space is formed inside the cover body, and the clamping mechanism and the image acquisition module are arranged in the detection space. The cover body can prevent the external environment from affecting the normal operation of the visual detection mechanism and can also prevent impurities and the like from interfering with the work of other mechanisms.

[0011] To solve the second technical problem, the present utility model provides a lock body detection device. The pressing mechanism includes a pressing member and a first driving source for driving the pressing member to move closer to or away from the lock tongue. A pressure sensor is provided on the pressing member. Through the pressure sensor, the pressure value when the lock tongue extends can be effectively recorded. In addition, it can cooperate with the first driving source to drive the pressing member to press the lock tongue, or move synchronously in the direction away from the lock tongue under the pressure of the lock tongue as the lock tongue extends.

[0012] To enable the first driving source to have a high feedback accuracy, preferably, the first driving source is a servo electric cylinder, and the pressure sensor is arranged between the pressing member and the first driving source. Such a design is considered because the commonly used first driving source is a cylinder, and the cylinder is easily affected by air pressure, resulting in ineffective feedback. Arranging the pressure sensor between the pressing member and the first driving source can also prevent the pressure sensor from being damaged by directly contacting the locking tongue.

[0013] Furthermore, to achieve the pressing function of the pressing member, preferably, the pressing member is a columnar pressing head. According to actual working needs, the pressing member can be set as a columnar pressing head such as a cylindrical shape or a prismatic shape.

[0014] To be able to record detection data and control the cooperation of each mechanism, preferably, a control module is further included. The control module is signal-connected to the pressing mechanism and the visual detection mechanism, so as to control the pressing member to move close to the locking tongue when the locking tongue retracts. And controlling the pressing member to move close to the locking tongue when the locking tongue retracts is to enable the pressing member and the pressure sensor to detect the pressure value of the locking tongue extending out when the locking tongue then extends.

[0015] To enable the clamping mechanism to fix the lock body and be able to install the rotating mechanism, preferably, the clamping mechanism includes a fixture plate, the rotating mechanism includes a second driving source for driving the locking tongue to extend and retract, and a through hole for the power output shaft of the second driving source to pass through is provided on the fixture plate.

[0016] Furthermore, to avoid wear or jamming between the power output shaft and the fixture plate, preferably, a bearing is also arranged between the power output shaft and the through hole. Through the bearing, not only can the working stability of the power output shaft be improved, but also its service life can be extended.

[0017] Compared with the prior art, the advantages of the present utility model are as follows:

[0018] 1. The lock body detection device is provided with a visual detection mechanism, which can efficiently identify the left and right layouts of the lock body through the image acquisition module, and can also judge the extending and retracting states of the locking tongue, so as to cooperate with the movement of other mechanisms, which is relatively accurate and efficient.

[0019] 2. Pressing the locking tongue by a servo electric cylinder and cooperating with a pressure sensor can more accurately detect the pressure value of the locking tongue extending out. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The following further describes the present utility model in detail with reference to specific embodiments.

[0030] As Figures 1 to 9 shown, it is a preferred embodiment of the present utility model. The lock body detection device in this embodiment includes a clamping mechanism 1 for fixing the lock body A. A rotating mechanism 2 is arranged on the clamping mechanism 1, and the rotating mechanism 2 is connected to the rotating shaft hole C corresponding to the lock tongue B to drive the lock tongue B to extend and retract. Correspondingly, a pressing mechanism 3 for pressing and testing the pressure value of the lock tongue B is further arranged in front of the extending direction of the lock tongue B. Further, the lock body detection device in this embodiment further includes a visual detection mechanism 4, and the visual detection mechanism 4 includes an image acquisition module 41 for identifying the left and right formats of the lock body A.

[0031] And in order to facilitate the image acquisition module 41 to identify the left and right formats of the lock body A, as Figure 2 、 Figure 3As shown in the figure, the visual inspection mechanism 4 further includes a light source 42 adjacent to the lock tongue B. The light source 42 is provided for two purposes. On the one hand, it facilitates the image acquisition module 41 to effectively utilize the gray-scale threshold to detect the left and right layouts of the lock body A. On the other hand, it can also use the image acquisition module 41 to judge the extended and retracted states of the lock tongue B, so as to cooperate with the pressing mechanism 3 to move. Further, in order to improve the cooperation effect between the image acquisition module 41 and the light source 42, the image acquisition module 41 is located on one side of the lock body A in the thickness direction, and two light sources 42 are provided, which are respectively arranged on both sides in front of the extending direction of the lock tongue B. Setting the image acquisition module 41 on one side of the lock body A in the thickness direction is to make the line of sight of the image acquisition module 41 perpendicular to the extending direction of the lock tongue B. At the same time, light sources 42 are arranged on both sides in front of the extending direction of the lock tongue B, which can use the lock tongue B to more clearly identify the left and right layouts of the lock body A. The image acquisition module 41 in this embodiment is as Figure 5 shown, and the light source 42 is as Figure 6 shown. As Figure 1 、 Figure 2 shown, in order to avoid interference from the external environment during the detection process of the lock body A, the lock body detection device in this embodiment further includes a cover body 5. A detection space 51 is formed inside the cover body 5, and the clamping mechanism 1 and the image acquisition module 41 are arranged in the detection space 51. The cover body 5 can prevent the external environment from affecting the normal operation of the visual inspection mechanism 4, and can also prevent, for example, impurities from interfering with the work of other mechanisms.

[0032] Further, as Figure 7 shown, the pressing mechanism 3 in this embodiment includes a pressing member 31 and a first driving source 32 for driving the pressing member 31 to move closer to or away from the lock tongue B. A pressure sensor 33 is arranged on the pressing member 31. Through the pressure sensor 33, the pressure value when the lock tongue B extends can be effectively recorded. In addition, it can cooperate with the first driving source 32 to drive the pressing member 31 to press the lock tongue B, or move in the direction away from the lock tongue B synchronously under the pressure of the lock tongue B as the lock tongue B extends. In order to enable the first driving source 32 to have a high feedback accuracy, the first driving source 32 in this embodiment is a servo electric cylinder, and the pressure sensor 33 is arranged between the pressing member 31 and the first driving source 32. Such a design is considered because the commonly used first driving source 32 is a cylinder, and the cylinder is easily affected by air pressure and cannot provide effective feedback. Arranging the pressure sensor 33 between the pressing member 31 and the first driving source 32 can also prevent the pressure sensor 33 from being damaged by directly contacting the lock tongue B. In addition, the pressing member 31 in this embodiment is a columnar pressing head.

[0033] In order to record the detection data and control the cooperation of each mechanism, the lock body detection device in this embodiment further includes a control module. The control module is signal-connected to the pressing mechanism 3 and the visual detection mechanism 4, so as to control the pressing member 31 to move closer to the lock tongue B when the lock tongue B retracts. And controlling the pressing member 31 to move closer to the lock tongue B when the lock tongue B retracts is to enable the pressing member 31 and the pressure sensor 33 to detect the pressure value when the lock tongue B extends later. In order to enable the clamping mechanism 1 to fix the lock body A and install the rotating mechanism 2, the clamping mechanism 1 in this embodiment further includes a fixture plate 11. The rotating mechanism 2 includes a second driving source 21 for driving the lock tongue B to extend and retract, and a through hole 12 for the power output shaft 22 of the second driving source 21 to pass through is provided on the fixture plate 11. Further, in order to avoid wear or jamming between the power output shaft 22 and the fixture plate 11, a bearing 23 is provided between the power output shaft 22 and the through hole 12 in this embodiment. And through the bearing 23, not only can the working stability of the power output shaft 22 be improved, but also its service life can be extended.

[0034] The following is the specific use process of the lock body detection device in this embodiment:

[0035] As Figure 4 shown, the lock body A has three lock tongues B, which are the auxiliary lock tongue, the diagonal tongue, and the square tongue from top to bottom. After the auxiliary lock tongue retracts, the diagonal tongue and the square tongue cannot retract. After the detection starts, first, the visual detection mechanism 4 is used to judge the left and right layouts of the lock body A. Then, the rotating mechanism 2 drives the diagonal tongue to retract. At this time, if the visual detection mechanism 4 can recognize that the diagonal tongue retracts, the pressing mechanism 3 will drive the corresponding pressing member 31 to move towards the diagonal tongue and contact the diagonal tongue. Then, the rotating mechanism 2 drives the diagonal tongue to extend. After the corresponding pressing member 31 receives the pressure from the diagonal tongue, it moves synchronously with the diagonal tongue and records the pressure value of the diagonal tongue. Thereafter, the same detection process as that of the diagonal tongue is repeated for the square tongue. Finally, the rotating mechanism 2 drives the auxiliary lock tongue to retract. At this time, the pressing mechanism 3 presses the diagonal tongue and the square tongue, and neither the diagonal tongue nor the square tongue can be retracted. Then, the rotating mechanism 2 drives the diagonal tongue and the square tongue to also not be retracted, and the lock body A is detected to be qualified.
