Description

Technical Field

[0001] This utility model belongs to the field of screw feeding technology, and in particular relates to a screw vibration feeding device. Background Technology

[0002] In industrial automated production, an efficient and stable supply of screws is crucial for ensuring the continuity of assembly processes. Currently, most mainstream mechanical feeding equipment uses a vibratory feeder combined with a linear guide conveyor, but this approach still has many limitations in practical applications.

[0003] In existing devices, the connection between the track and the hopper often suffers from insufficient dimensional adaptability, leading to screw accumulation or jamming in the transition area and affecting the smoothness of feeding. In precision assembly scenarios, screws need to be transported in a specific posture, but the guide structure of traditional tracks lacks refined design, making them prone to posture deviation and increasing the cost of subsequent positioning and correction processes. Utility Model Content

[0004] In view of the above problems, the purpose of this utility model is to provide a screw vibration feeding device, which aims to solve the problems of easy accumulation or jamming when the track and hopper are connected in the existing screw feeding device, and easy deviation of screw posture.

[0005] The present invention adopts the following technical solution:

[0006] The screw vibratory feeding device includes a machine base, with a support frame and a vertical frame at the front and rear of the machine base. A vibrator is mounted on the support frame, and a guide rail is mounted on the vibrator. A hopper is mounted on the vertical frame, and a discharge port is opened on the hopper. The tail end of the guide rail is positioned towards the discharge port. A pusher and a pusher assembly are mounted on the vertical frame. The pusher assembly drives the pusher to move up and down. A bottom opening is opened at the bottom of the hopper, and the pusher is located inside the bottom opening. A transfer assembly is mounted on the support frame, directly opposite the front end of the guide rail. The transfer assembly includes a fixed frame, with a slide block mounted on the fixed frame. A fork block is laterally slidable within the slide block. A receiving groove is opened on the fork block directly opposite the front end of the guide rail. An arc-shaped groove is opened on the top of the receiving groove on the slide block. A guide seat is mounted on the fixed frame, and a transfer cylinder for driving the fork block to move is also mounted on the slide block. A sliding cylinder is mounted on the fixed frame, and the drive shaft of the sliding cylinder is connected to the slide block.

[0007] Furthermore, the hopper is provided with a connecting plate and a baffle on the front and rear sides of the discharge port, and the connecting plate and the baffle are arranged above and below each other. The connecting plate is provided with an adjusting plate, and the connecting plate has a round hole. The adjusting plate has an oblong groove. A locking screw is inserted into the round hole. After the locking screw passes through the oblong groove, it is locked by a locking nut.

[0008] Furthermore, the baffle is positioned directly opposite the material guide rail, and a discharge trough is formed in the center of the baffle. Notches are formed on both sides of the discharge trough on the baffle, and the left and right side plates of the material guide rail are located within the notches.

[0009] Furthermore, the pusher frame is slidably mounted on the upright frame, and the top of the pusher frame has a forward and downward inclined surface with a support groove on the downward-facing inclined surface. A driven wheel is rotatably mounted on the machine base, and a linkage plate is provided at the eccentric position of the driven wheel. The upper end of the linkage plate is rotatably connected to the pusher frame. The pusher assembly includes a drive motor, and a drive wheel is provided on the drive shaft of the drive motor. A belt is fitted between the drive wheel and the driven wheel.

[0010] The beneficial effects of this utility model are:

[0011] 1. This device improves the dimensional adaptability of the connection between the guide rail and the hopper by setting the guide rail opposite to the hopper outlet and cooperating with the baffle and the left and right side plates of the guide rail. This effectively reduces the accumulation or jamming of screws in the transition area and ensures smooth feeding. 2. Under the action of the vibrator, the guide rail keeps the screws in a certain posture during transport. Simultaneously, the arc-shaped groove on the slide can position the screw head, reducing screw posture deviation and lowering the cost of subsequent positioning and correction processes.

[0017] To make the objectives, technical solutions, and advantages of this utility model patent clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the scope of the present utility model.

[0018] To illustrate the technical solution described in this utility model, specific embodiments are described below.

[0019] For ease of explanation, only the parts relevant to the embodiments of this utility model are shown.

[0020] Combination Figure 1-5 As shown, the screw vibratory feeding device includes a machine base 1, with support frames 2 and upright frames 3 at the front and rear of the machine base 1. A vibrator 4 is mounted on the support frame 2, and a guide rail 5 is mounted on the vibrator 4. A hopper 6 is mounted on the upright frame 3, and a discharge port 7 is opened on the hopper 6. The tail end of the guide rail 5 faces the discharge port 7. A pusher 8 and a pusher assembly are mounted on the upright frame 3. The pusher assembly drives the pusher 8 to move up and down. A bottom opening 9 is opened at the bottom of the hopper, and the pusher 8 is located inside the bottom opening. The support frame 2 is directly opposite... The front end of the guide rail 5 is provided with a transfer assembly, which includes a fixed frame 10. The fixed frame 10 is provided with a slide block 11. A fork block 12 is slidably arranged in the slide block 11. The fork block 12 has a receiving groove 13 facing the front end of the guide rail. The slide block 11 has an arc-shaped groove 14 at the top of the receiving groove. The fixed frame 10 is provided with a guide seat 15. The slide block 11 is also provided with a transfer cylinder 16 for driving the fork block to move. The fixed frame 10 is provided with a sliding cylinder 17. The drive shaft of the sliding cylinder is connected to the slide block 11.

[0021] When using this device to feed screws, a certain number of screws are first poured into the hopper. The vibrator is activated, causing the guide rail to vibrate. The screws in the hopper enter the guide rail from the outlet and move directionally along the guide rail under the action of vibration. At the same time, the pusher moves up and down, pushing the screws at the bottom of the hopper upwards to replenish the guide rail. When the screws move to the front end of the guide rail, they enter the receiving groove of the fork block. The arc groove on the slide block positions the screw head, and then the sliding cylinder drives the slide block to move, transferring the screw to directly above the guide seat. Immediately afterwards, the transfer cylinder drives the fork block to retract, the fork block disengages from the screw, and the screw falls into the guide seat.

[0022] As a preferred structure, combined with Figure 1 , Figure 4 The hopper 6 is provided with a connecting plate 18 and a baffle 19 on the front and rear sides of the discharge port 7, respectively, and the connecting plate 18 and the baffle 19 are arranged vertically. The connecting plate 18 is provided with an adjusting plate 20. The connecting plate 18 has a round hole 21, and the adjusting plate 20 has an oblong groove 22. A locking screw (not shown in the figure) is inserted into the round hole 21. After the locking screw passes through the oblong groove, it is locked by a locking nut.

[0023] In practice, the height limit of the adjusting plate can be changed by adjusting the position of the adjusting plate relative to the connecting plate and fixing it with locking screws and locking nuts, so as to adapt to the discharge gap of screws of different specifications.

[0024] In addition, such as Figure 4The baffle is positioned directly opposite the guide rail. A discharge trough 23 is formed in the center of the baffle 19, and notches 24 are formed on both sides of the discharge trough. The left and right side plates of the guide rail 5 are located within the notches 24. This design allows the baffle to better cooperate with the guide rail, precisely guiding the screw discharge and preventing the screw from deviating from the rail during the discharge process.

[0025] Furthermore, as a preferred structure, such as Figure 5 The pusher frame 8 is slidably mounted on the upright frame 3. The top of the pusher frame 8 has a forward and downward inclined surface, and a support groove 25 is opened on the downward inclined surface. A driven wheel 26 is rotatably provided on the machine base 1. A linkage plate 27 is provided at the eccentric position of the driven wheel 26. The upper end of the linkage plate 27 is rotatably connected to the pusher frame 8. The pusher assembly includes a drive motor 28. A drive wheel 29 is provided on the drive shaft of the drive motor 28. A belt 30 is sleeved between the drive wheel 29 and the driven wheel 26.

[0026] In this structure, the bottom of the hopper has an opening, and the pusher is located inside the opening. The pusher moves up and down under the action of the pusher assembly, which can push the screws in the hopper, helping the screws to fall smoothly into the guide rail and preventing the screws from accumulating and blocking at the bottom of the hopper.

[0027] Specifically, the jacking frame is slidably mounted on the upright frame, and the top of the jacking frame has a forward-facing and downward-facing inclined surface with a support groove. This design allows the jacking frame to better contact the screw when jacking it, providing a stable jacking force, while the support groove prevents the screw from slipping off during the jacking process.

[0028] When the pusher frame moves up and down, the drive motor works, driving the drive wheel and driven wheel to rotate via the belt, which in turn drives the pusher frame to move up and down via the linkage plate, thus replenishing the screws in the hopper.

[0029] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
