Description

Technical Field

[0001] This utility model proposes a lock feeding and testing device, which belongs to the field of precision lock testing. Background Technology

[0002] In the precision inspection of locks, accurate loading is crucial for ensuring subsequent assembly accuracy and reducing defect rates. Current loading and inspection systems typically employ automated production lines using turntables and fixtures, relying on sensors to detect the presence of products and ensure correct loading positions. However, existing photoelectric sensors are often rigidly mounted on the base using fixed brackets, making it impossible to adjust their angle and height according to the different lock models. Furthermore, the existing sensor mounting structures are often custom-designed, with different locks requiring separate, custom-made brackets, mostly welded to the base. Disassembly for cleaning or replacement requires complete bracket removal, leading to lengthy maintenance and significantly reduced production efficiency. Therefore, a lock loading and inspection device with adjustable angles, high adaptability, and stable installation is needed to meet the flexible production needs of various lock types, improving inspection accuracy and production line stability. Utility Model Content

[0003] To address the technical problems existing in the prior art, this utility model proposes a lock feeding and detection device to improve the adaptability and stability of lock detection. The technical features adopted are as follows:

[0004] A lock loading and testing device includes a base, a turntable, and a testing fixture fixed to the edge of the turntable. The testing fixture rotates synchronously with the turntable. When the testing fixture rotates to a position below the loading station, a testing component is installed. The testing component is supported by a fixed rod, which is fixed to the mounting hole of the base by a bottom fixing member. The upper end of the fixed rod is connected to a rotary joint, and the other end of the rotary joint is detachably connected to a photoelectric sensor through a rotary connecting piece.

[0005] Preferably, the bottom fixing component includes a connecting hole seat and a locking pin. The connecting hole seat has at least two connection ports around its perimeter that are fixed to the machine base. Above the connecting hole seat is a locking pin that runs through the middle. The locking pin has a bolt interface with one side having a cross-section and an adjustable diameter.

[0006] Preferably, the rotary joint comprises at least two mirrored components spliced ​​together, and the mirrored components include a bolt fixing end, a fixing rod groove end, and an elastic steel sheet.

[0007] Preferably, the grooved ends of the fixing rod are spliced ​​to form an annular inner diameter structure, and the fixing end is fixed to the fixing rod by tightening the bolt.

[0008] Preferably, the elastic steel sheet is located at one end of the mirror assembly near the rotating connecting piece, and the rotating connecting piece has a circular hole in the middle that is smaller than the maximum expansion of the elastic steel sheet. The elastic steel sheet is pre-pressed into the circular hole of the rotating connecting piece for movable engagement.

[0009] Preferably, the rotating connecting piece has at least two sets of sensor fixing holes around its perimeter.

[0010] Preferably, the feeding detection device is also equipped with a protection device, which is identical to the detection component.

[0011] Preferably, the photoelectric sensor probe of the protection device faces the outer edge of the detection fixture.

[0012] The beneficial effects of this utility model are as follows:

[0013] By cooperating with the groove end of the rotating joint fixing rod and the bolt fixing end, the photoelectric sensor on the rotating joint can be adjusted 360°. In addition, the height can also be adjusted with the fixing rod. The pre-compression design of the elastic steel sheet ensures that the rotating joint can maintain a stable angle after rotation, avoiding sensor angle deviation caused by equipment vibration. It can be adapted to lock materials of different sizes, and can be quickly adjusted after changing the test product, thereby improving adaptation efficiency and testing flexibility.

[0014] The bottom fixing component ensures a close fit with the base through multiple connection ports, and the adjusting bolt reduces the inner diameter of the clamping column to achieve rigid clamping, solving the problem of vibration displacement of traditional single bolt fixing of sensors, and enhancing installation stability and detection accuracy.

[0015] The photoelectric sensor is detachably connected to the rotary joint via a rotating connecting piece. Disassembly can be performed simply by prying open the elastic steel sheet, which shortens the cleaning or replacement time and improves maintenance efficiency.

[0016] The horizontal protection device supplements the lateral offset detection, forming a dual protection of vertical presence / absence detection and lateral offset detection, avoiding machine collision failures caused by material offset and human error. Attached Figure Description

[0026] The present invention will be further described below with reference to specific embodiments, but the present invention is not limited to the embodiments.

[0027] In the description of this utility model, it should be noted that the terms "center", "longitudinal", "lateral", "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer" and "vertical" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0028] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; or they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0029] Furthermore, in the description of this utility model, unless otherwise stated, "multiple", "multiple groups", and "multiple roots" mean two or more.

[0030] Unless otherwise specified, the materials, instruments and methods used in the following embodiments are all conventional materials, instruments and methods in the art and can be obtained through commercial channels.

[0031] Figure 1This is a schematic diagram of the lock feeding and detection device of this utility model. The base 1 is fixed on the workbench of the production line. The turntable 2 is connected to the drive motor inside the base 1 through the central rotating shaft. The detection fixture 3 is evenly fixed to the edge of the turntable 2 by bolts. The inner side of the fixture is provided with a clamp that matches the shape of the lock.

[0032] like Figure 2 and Figure 4 As shown, the connecting hole seat 421 of the bottom fixing component 42 is fixed to the preset mounting hole of the base 1 by at least two M8 bolts around its perimeter. The number of bolts can be appropriately increased according to the force on the component. The clamping post 422 above the connecting hole seat has a cross section on one side. The clamping post side wall of the cross section has an adjusting bolt interface 423. The adjusting bolt interface 423 clamps the fixing rod 41 with an M6 adjusting bolt. By tightening the adjusting bolt, the inner diameter of the clamping post is reduced, thereby achieving the vertical positioning of the fixing rod 41. The preset mounting hole of the base 1 can be drilled according to the installation position of the fixing rod. In addition, the upper limit of the height of the fixing rod can be finely adjusted by loosening the bolt.

[0033] like Figure 3 and Figure 5 As shown, the rotary joint 43 is composed of two mirror-image components 431. Each mirror-image component has a bolt fixing end 4311 on one side, a fixing rod groove end 4312 in the middle, and an elastic steel sheet 4313 at the end near the rotary connecting piece 44. The bolt fixing end 4311 is connected by two M4 bolts. The bolts are connected, and the groove end 4312 of the fixing rod is spliced ​​to form an annular inner diameter structure. This inner diameter structure is fixed to the fixing rod 41 after the bolts are tightened. The rotating connecting piece 44 has a hole in the middle that is smaller than the maximum expansion degree of the elastic steel sheet 4313. The elastic steel sheet 4313 is moved and engaged by being squeezed into the hole of the rotating connecting piece 44. The steel sheet is embedded in the round hole after slight deformation, so as to achieve a detachable connection. The rotating connecting piece 44 has at least two sets of sensor fixing holes around its perimeter. In this embodiment, there are two sets of sensor fixing holes. The corresponding hole is selected according to the size of the lock material. In this embodiment, the photoelectric sensor 45 and the rotating connecting piece 44 are fixed by bolts. The photoelectric sensor selected is a diffuse reflection type photoelectric sensor. The sensor probe faces the material placement area of ​​the detection fixture 3. By cooperating with the rotary joint 43 and the rotary connecting plate 44, the rotary joint 43 can rotate 360° laterally around the fixed rod 41, and the rotary connecting plate 44 can rotate 360° longitudinally through the rotary joint 43. After rotation, the rotary connecting plate 44 maintains its current angular position due to the rebound force and friction of the elastic steel sheet.

[0034] In addition, to ensure the safety of the detection process, a protection device 5 with the same structure as the detection device 4 is set on the same side of the detection device 4. The protection device 5 only adjusts the sensor direction to be horizontal, and its photoelectric sensor probe faces the outer edge of the detection fixture 3. When the photoelectric sensor on the outer edge detects a signal, it indicates that the installed material exceeds the safe distance, or there is other situation that hinders safe production. The sensor of the protection device triggers a signal, which controls the turntable 2 to pause through the PLC to prevent the offset material from entering the subsequent process.

[0035] The workflow of this utility model is as follows:

[0036] Debugging phase: According to the size of the lock to be tested, loosen the adjusting bolt of the bottom fixing part 42 and adjust the height of the fixing rod 41 so that the sensor probe is aligned with the detection position of the clamp slot; rotate the rotary joint 43 so that the sensor probe is vertically aligned with the bottom of the slot to ensure that the light can be blocked after the material is put in; adjust the horizontal sensor of the protection device to a distance of 2-5mm from the outside of the clamp.

[0037] Detection Phase: Turntable 2 drives the detection fixture 3 to rotate. When the fixture reaches the loading station, the operator places the material into the detection fixture slot. If the material is placed without missing or offset, the photoelectric sensor 45 of the detection component detects the material. Since the material blocks the light, the sensor outputs a high-level signal, and the turntable continues to rotate. If the material is not placed, the sensor is unobstructed and outputs a low-level signal. The PLC controls the turntable to pause and alarm. If the material shifts laterally or the protection device is obstructed laterally, the sensor of the protection device 5 is triggered, and the turntable also pauses and alarms.

[0038] The detection methods, data analysis and control methods involved in this utility model are all existing technologies in this field. This utility model does not improve any software programs and methods. This utility model only improves the hardware structure design. The PLC control implementation methods or software programs are all based on existing methods or software program design books, manuals or product manuals by those skilled in the art, combined with the functions involved in the principles and effects of this utility model, and can be implemented by writing their own programs.

[0039] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Anyone skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be determined by the claims.
