Abstract
Description
Technical Field
[0001] The utility model relates to the field of blade lock processing equipment, in particular to a blade detection device. Background Art
[0002] The blade lock is a very common lock on the market. The blade lock head is generally composed of a lock core with a needle roller locking mechanism and a shell. The lock core with a needle roller locking mechanism is composed of a blade, a needle roller and a lock core sleeve. The blade can rotate a certain angle in the lock core sleeve. Each blade is provided with a needle roller groove with different angles, and a slide groove for placing the needle roller is provided on the side wall of the lock core sleeve. When unlocking, the key tooth groove contacts the key jack in the middle of the blade. When the blade is rotated to the designed position, the needle roller grooves on all the blades are on the same straight line, and the needle roller falls into the needle roller groove of the blade, so that the lock core sleeve can rotate relative to the shell to unlock; when locking, the key is rotated to make the needle roller groove on the blade misaligned, and the needle roller is ejected from the needle roller groove and locked with the shell.
[0003] During the assembly of the blade lock, the blade needs to be installed into the blade sleeve or the blade slot of the receiving device. In order to avoid the loss of blades during the blade assembly process, the prior art generally sets a sensor in the blade feed channel, so that an alarm can be given when the blade stock in the blade feed channel is low. However, this solution can only ensure that the blade feeding is normal, but cannot ensure whether the subsequent blades are installed in the blade sleeve or the blade slot of the receiving device, so it needs to be improved. Summary of the invention
[0004] In order to solve the above problems, the purpose of the utility model is to provide a blade detection device, through which it is possible to accurately determine whether the blade is pushed into the blade sleeve or the blade slot of the material receiving device, thereby ensuring the accuracy of lock core assembly.
[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions:
[0006] A blade detection device comprises a blade hopper and a feeding support plate attached to the lower end surface of the blade hopper; the blade hopper is provided with a blade feed channel, and the feeding support plate is constructed with a feeding trough connected with the blade feed channel; a feeding push piece is movably arranged on the feeding trough; it is characterized in that: a through hole is constructed on the pushing end of the feeding push piece, and the through hole is arranged along the length direction of the feeding push piece and extends to the end; it also includes a light detection component, and the detection path of the light detection component passes through the conveying path of the through hole of the feeding push piece.
[0007] The utility model adopts the above technical scheme, which relates to a blade detection device, in which a blade feed channel in the blade detection device is used for feeding blades, and the blades enter the feed trough from the bottom of the blade feed channel and are sent out from the outlet end of the feed trough through the feed push piece. On this basis, the scheme is provided with a light detection component on the outlet end side of the feed trough, and a through hole is constructed on the push end of the feed push piece, requiring the detection path of the light detection component to pass through the conveying path of the through hole of the feed push piece. When the equipment is running, the push end of the feed push piece has a blade in a normal state, and when the blade passes through the detection path of the light detection component, the edge of the blade will instantly block the reception of the light detection component, so that it can be judged that the blade is assembled normally. When the blade is missing from the push end of the feed push piece, since the detection path of the light detection component passes through the conveying path of the through hole of the feed push piece, there is no blade blocking the detection path of the light detection component and at the same time, the feed push piece will not block the detection path due to the setting of the through hole, so that it can be judged that the blade is missing and an alarm signal is given.
[0008] Through the above solution, it is possible to accurately determine whether the blade is pushed into the blade sleeve or the blade slot of the material receiving device, thereby ensuring the accuracy of lock core assembly.
[0009] In a specific embodiment, the optical detection assembly includes a transmitting component and a receiving component located at the upper and lower sides of the outlet end of the feeding trough; the transmitting end of the transmitting component faces the receiving component. The receiving component is used to receive the laser signal emitted by the transmitting component. When the blade blocks the laser signal during the feeding process, it can be determined that the blade is assembled normally.
[0010] Preferably, the feeding push piece is connected to the output end of the feeding cylinder.
[0011] In a further solution, the push end of the feed push piece is constructed as an arc groove that matches the blade profile, and the through hole is connected to the arc groove. In a specific embodiment, the blade feed channel includes a main channel for the blade body to pass through, and a secondary channel for the protrusion of the blade to pass through; the through hole on the feed push piece is connected and adapted to the secondary channel, and when the blade is on the push end of the feed push piece, the protrusion on the blade is embedded in the through hole of the feed push piece. In this solution, the arc groove is used to adapt and position the blade to prevent the blade from detaching; and the protrusion on the blade is embedded in the through hole of the feed push piece, which can prevent the blade from rotating during the conveying process and causing angular misalignment.
[0012] Preferably, a blade sleeve or a material receiving device for receiving blades is constructed on the outlet end of the feeding trough, so that the blades can be directly loaded into the blade sleeve or first installed in the material receiving device. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] like Figures 1 to 3 As shown, this embodiment relates to a blade detection device, including a blade hopper 1, a light detection component, and a feeding support plate 2 attached to the lower end surface of the blade hopper 1. The blade hopper 1 is provided with a blade feed channel 11, and the feeding support plate 2 is constructed with a feeding trough 21 connected to the blade feed channel 11. A feeding push piece 3 is movably arranged on the feeding trough 21, and the feeding push piece 3 is connected to the output end of the feeding cylinder. A through hole 31 is constructed on the pushing end of the feeding push piece 3, and the through hole 31 is arranged along the length direction of the feeding push piece 3 and extends to the end.
[0022] The detection path of the optical detection component passes through the conveying path of the through hole 31 of the feeding push piece 3. In a specific embodiment, the optical detection component includes a transmitting component 51 and a receiving component 52 located at the upper and lower sides of the outlet end of the feeding trough 21. The transmitting end of the transmitting component 51 faces the receiving component 52. The receiving component 52 is used to receive the laser signal emitted by the transmitting component 51. When the blade blocks the laser signal during the feeding process, it can be judged that the blade is assembled normally.
[0023] The blade feed channel 11 in the blade detection device is used to feed blades 9. The blades 9 enter the feed trough 21 from the bottom of the blade feed channel 11 and are sent out from the outlet end of the feed trough 21 through the feed push piece 3. A blade sleeve or a receiving device for receiving blades is constructed on the outlet end of the feed trough 21. The blades can be directly loaded into the blade sleeve or installed in the receiving device first. On this basis, the present scheme is provided with a light detection component on the outlet end side of the feed trough 21, and a through hole 31 is constructed on the push end of the feed push piece 3. It is required that the detection path of the light detection component passes through the conveying path of the through hole 31 of the feed push piece 3. When the equipment is running, the push end of the feed push piece 3 has a blade in a normal state. When the blade passes through the detection path of the light detection component, the edge of the blade will instantly block the reception of the light detection component, so that it can be judged that the blade is assembled normally. When a blade is missing from the pushing end of the feeding push piece 3, since the detection path of the light detection component passes through the conveying path of the through hole 31 of the feeding push piece 3, there is no blade blocking the detection path of the light detection component and the feeding push piece 3 will not block the detection path due to the setting of the through hole 31, so it can be judged that the blade is missing and an alarm signal is given. Through the above scheme, it can be accurately judged whether the blade is pushed into the blade sleeve or the blade slot of the material receiving device, thereby ensuring the accuracy of the lock core assembly.
[0024] In a further solution, the push end of the feed push piece 3 is constructed as an arc groove 32 adapted to the profile of the blade 9, and the through hole 31 is connected to the arc groove 32. In a specific embodiment, the blade feed channel 11 includes a main channel 111 for the blade body to pass through, and a secondary channel 112 for the protrusion of the blade to pass through. The through hole 31 on the feed push piece 3 is adapted to the secondary channel 112, and when the blade is on the push end of the feed push piece 3, the protrusion 91 on the blade 9 is embedded in the through hole 31 of the feed push piece 3. In this solution, the arc groove 32 is used to adapt and position the blade to prevent the blade from detaching. The protrusion on the blade is embedded in the through hole 31 of the feed push piece 3, which can prevent the blade from rotating during the conveying process and causing angular misalignment.
