Description

Technical Field

[0001] The utility model relates to the field of screw production, in particular to a piece-by-piece feeding component used in a screw detection mechanism. Background Art

[0002] After production, screws need to be inspected for their length, appearance, and other factors. Regarding screw length detection, Chinese patent CN111006596A discloses a screw inspection device that uses a sensor to detect the lower limit of the screw length, and physical support to detect the upper limit of the length. However, since the screw moves on the conductive mechanism through the vibration of a vibrator, the screw will also vibrate. Therefore, even if the upper and lower limits of the length are set, the amplitude may cause false detection of the screw. Therefore, in order to improve the accuracy of the detection results, a separate screw detection mechanism is set up to detect the screws one by one. Therefore, there is an urgent need for a device that can feed the screws one by one into the screw detection mechanism. Utility Model Content

[0017] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0018] A screw detection mechanism for discharging material one by one component, such as Figure 1-Figure 5 As shown, it includes a storage block 1, a push rod 2, a drive assembly 3 and a one-way pin 4. A through-guide trough 11 is provided on the storage block 1, and a recessed mounting groove is provided on one side wall of the discharge end of the guide trough 11. The one-way pin 4 is provided in the mounting groove, and a one-way passage 5 is formed between the one-way pin 4 and the storage block 1. The drive assembly 3 is provided on the storage block 1, and the push rod 2 is rotated on the drive assembly 3 by a torsion spring; wherein, the push rod 2 rotates within a limited range, that is, the torsion spring provides a driving force for the push rod 2, so that the push rod 2 cannot be excessively reset after the initial position. The push rod 2 moves horizontally through the drive assembly 3, and the last screw is pushed out of the guide trough 11 by the push rod 2. During this process, the push rod 2 passes through the passage 5.

[0019] When using, Figure 1-Figure 5 As shown, the storage block 1 is connected to a vibration plate, through which the screws are arranged and then fed into the guide trough 11 of the storage block 1. The push rod 2 is inserted between the last two screws, and the drive assembly 3 drives the push rod 2 to move toward the discharge end of the guide trough 11, and the screw is pushed out by the push rod 2. When the push rod 2 is reset, because the one-way pin 4 can only pass in one direction, the push rod 2 is blocked by the one-way pin 4 and rotates counterclockwise. After the push rod 2 passes the one-way pin 4, it is subjected to the restoring force of the torsion spring and rotates clockwise before resetting. Among them, the installation position of the one-way pin 4 corresponds to the position of the last screw. The one-way pin 4 is provided to prevent the push rod 2 from interfering with the screw when resetting.

[0020] In one embodiment, if Figure 1-Figure 5 As shown, the drive assembly 3 includes an actuator 31, a guide rail 32, and a slider 33. The slider 33 is slidably mounted on the storage block 1 via the guide rail 32. The actuator 31 drives the slider 33 to move horizontally along the guide rail 32. A stopper 331 and a rotating shaft are provided on the slider 33. The pusher rod 2 is rotationally connected to the rotating shaft via a torsion spring. The stopper 331 limits the initial position of the pusher rod 2 and is used to support the pusher rod 2 to push the screw out of the guide trough 11. The actuator 31 is a pneumatic cylinder.

[0021] In one embodiment, if Figure 1-Figure 5As shown, a guide portion 12 is provided within the mounting slot, extending between the last two screws. This guide portion 12 guides the push rod 2 into position between the last two screws. The push rod 2 follows a curved trajectory. When the push plate 2 passes the one-way pin 4 during its reset, the push rod 2 rotates clockwise due to the restoring force of the torsion spring, acting on the guide portion 12. When the actuator 31 drives the slider 33 to the right, the push rod 2 moves rightward along the guide portion 12, extending between the last two screws. After the push rod 2 separates from the guide portion 12, it guides the push rod 2 into position between the two screws, allowing the push rod 2 to drive one screw out of the guide slot 11. The guide portion 12 is flat.

[0022] In one embodiment, if Figure 1-Figure 5 As shown, the one-way pin 4 includes a fixed seat 41, a spring 42, and a pin 43. A spring chamber and a guide chamber are provided within the fixed seat 41. The spring 42 is disposed within the spring chamber, and the pin 43 is slidably connected to the guide chamber. The two ends of the spring 42 act on the bottom of the guide chamber and one end of the pin 43. A slanted guide portion 431 is provided on one side of the other end of the pin 43. When the push rod 2 moves from left to right, it contacts the slanted guide portion 431 of the pin 43, and the pin 43 moves downward along the axis, causing the pin 43 to disappear within the fixed seat 41. Simultaneously, the spring 42 accumulates force. When the push rod 2 separates from the pin 43, the pin 43 is reset by the restoring force of the spring 42. When the push rod 2 moves from right to left, because there is no slanted guide portion 431 on the other side of the pin 43, the pin 43 blocks the push rod 2, causing it to rotate counterclockwise to pass through the one-way pin 4.

[0023] In one embodiment, if Figure 1-Figure 5 As shown, retaining springs 6 are provided on both sides of the discharge end of the material guide trough 11 , and the retaining springs 6 are used to restrict the screw in the material guide trough 11 .

[0024] When the utility model is used, Figure 1-Figure 5 As shown, the storage block 1 is tilted and connected to the vibrating plate, and the screws are arranged in the guide groove 11. The screws are blocked by the retaining spring 6 and arranged in sequence in the guide groove 11. The position of the one-way pin corresponds to the last screw, so the actuator 31 drives the slider 33 to move to the left through the one-way pin 4. Since the one-way pin 4 can only pass from left to right, the one-way pin 4 blocks the push rod 2 to make it rotate. When the push rod 2 is no longer in contact with the pin 43 of the one-way pin 4, it is rotated in the opposite direction by the restoring force of the torsion spring and acts on the guide part 12. The slider 33 is driven in the reverse direction, and the push rod 2 follows the edge of the guide part 12 and is gradually inserted between the last two screws. The push rod 2 is continued to be driven to the right, moving the last screw toward the outlet end. During this process, the pin 43 of the one-way pin 4 contracts inward, causing the push rod 2 to pass through the one-way pin 4. At this point, the unloading of one screw is completed.

[0025] The above are only preferred embodiments of the present invention and are not intended to limit the scope of implementation of the present invention. Without departing from the spirit and scope of the present invention, modifications or equivalent replacements of the present invention should be included in the scope of protection of the claims of the present invention.
