Technical Field

[0001] The utility model relates to the technical field of automatic assembly of non-standard locks, in particular to an automatic positioning assembly machine. Background Art

[0002] The lock structure is generally divided into five parts: handle, lock plate, lock body, lock core and accessories. Among them, the lock plate is an important carrier for fixing the handle, lock plate, lock body, lock core and accessories. Not only the material and thickness are important, but also the assembly process is very important. A good assembly process can significantly improve the structural strength and durability of the lock.

DETAILED DESCRIPTION

[0038] The following is a specific embodiment of the present invention. People familiar with the technology can easily understand the other advantages and functions of the present invention from the contents disclosed in this specification. Obviously, the described embodiment is a part of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] Please refer to Figure 1-Figure 5 The automatic positioning assembly machine disclosed in the utility model is connected to the vibration feeder 1 and positions the lock plate components being assembled, including a rough positioner 2, a material transfer device 3, a fine positioner 4 and a general assembly table 5, wherein the rough positioner 2, the material transfer device 3 and the general assembly table 5 are linearly arranged in sequence on a base 6, and the base 6 is a truss structure with legs installed at the bottom. The material transfer device 3 is located above it, and is used to continuously move the lock plate for assembly on the rough positioner 2, the material transfer device 3 and the general assembly table 5. Specifically, the input end of the rough positioner 2 is connected to the vibration feeder 1, so that the lock plate first enters the rough positioner 2 for a positioning, so as to detect whether the appearance of the lock plate meets the standard, thereby completing the initial screening. On the other hand, a fine locator 4 is provided at the adjacent position of the coarse locator 2. Then, after the lock plate is confirmed to be correct by the coarse locator 2, the fine locator 4 will detect the punching position of the lock plate. After final confirmation, the lock plate is sent to the general assembly table 5 to complete the final assembly. The above-mentioned whole process is realized under automated conditions, and the efficiency can be significantly improved compared with manual assembly. At the same time, after two positioning and calibration, the accuracy of the lock plate will be significantly improved, thereby significantly improving the assembly accuracy of the lock.

[0040] In this embodiment, if Figure 2 and Figure 4 The material moving device 3 is mounted on the base 6 and is located above the fine locator 4 and the coarse locator 2, wherein three mounting positions are evenly arranged on the material moving device 3, the three mounting positions are arranged horizontally, and any mounting position is provided with a picking mechanism 7. When in use, the material moving device 3 can drive the three mounting positions to move synchronously, and the three mounting positions correspond to the coarse locator 2, the material moving device 3 and the general assembly table 5, thereby the continuous movement of the locking plate accessories can be realized through the picking mechanism 7 on the mounting position, thereby completing the assembly positioning of the workpiece one by one.

[0041] In this embodiment, if Figure 3 and Figure 5The rough positioner 2 includes a pushing cylinder 21, a limiting slider 23 and a pouring chute 25. One end of the pouring chute 25 is connected to the vibrating loader 1 and the other end is connected to the dividing guide rail 24. The pouring chute 25 is perpendicular to the dividing guide rail 24 so that the locking plate can be sent into the dividing guide rail 24. A pushing cylinder 21 is installed at the bottom of the dividing guide rail 24, and the pushing cylinder 21 can push the limiting slider 23 to move along the dividing guide rail 24. A coarse positioning groove 22 that matches the shape of the accessory is provided in the limit slider 23. The coarse positioning groove 22 is suitable for aligning with the pouring trough 25, and the limit slider 23 is pushed by the pushing cylinder 21 to move the locking plate in the dividing guide rail 24. Specifically, when the locking plate enters the coarse positioning groove 22, the distance between the edge of the locking plate and the inner wall of the coarse positioning groove 22 can be sensed by an industrial camera or a sensor. If the tolerance band between the two is too large, the equipment automatically determines that it is unqualified, and then the lock plate is moved out of the dividing guide rail 24 through the limit slider 23. On the contrary, when the lock plate is detected to meet the requirements, the limit slider 23 carries the lock plate forward and moves it to the fine locator 4 through the material moving device 3.

[0042] In a specific embodiment disclosed in the present utility model, Figure 3 The precision locator 4 includes a jig 41 and a pressure button 42, wherein a precision locating groove is arranged inside the jig 41, and the precision locating groove is suitable for embedding the lock plate. At the same time, a plurality of pressure buttons 42 are arranged in the precision locating groove, wherein the arrangement position of the pressure buttons 42 is consistent with the positioning holes and riveting holes on the lock plate. After the lock plate enters the precision locating groove, for the lock plate with qualified aperture and empty position, the pressure button 42 will be directly inserted into the positioning hole and the riveting hole. On the contrary, the lock plate will interfere with the pressure button 42, thereby triggering the pressure button 42. Once the pressure button 42 is triggered, it is determined that the position of the lock plate does not meet the standard, so that the accessory is removed in the assembly process before the next step of final assembly.

[0043] In some embodiments, Figure 4 The picking mechanism 7 includes a lifting cylinder 71 and a contact sensor 74. A picker is installed at the movable end of the lifting cylinder 71, wherein the picker can be an electromagnet 72 or a pneumatic clamp 73 to move the locking plate. On the other hand, a contact sensor 74 is installed on the rigid body of the lifting cylinder 71. When the contact sensor 74 senses the locking plate, the picker is started, thereby achieving the technical effect of automatically clamping and moving materials.

[0044] In some embodiments, Figure 2 and Figure 4The material moving device 3 includes a servo motor 31 and a connecting member 32. The main shaft end of the servo motor 31 is coaxially connected to the lead screw 34, and the housing of the servo motor 31 is fixedly mounted on the bracket 35. The connecting member 32 is slidably arranged on the track in the bracket 35, and a mounting beam 36 is fixed on the front side. The mounting beam 36 is provided with scale lines, and three mounting positions are arranged on the mounting beam 36. A camera position 33 is arranged on the top for installing an industrial camera for visual inspection.

[0045] Although the utility model has been described in detail above with general descriptions and specific embodiments, it is obvious to those skilled in the art that some modifications or improvements can be made to the utility model. Therefore, these modifications or improvements made without departing from the spirit of the utility model are within the scope of protection claimed by the utility model.
