Description

Technical Field

[0001] This utility model relates to the field of material conveying technology, and in particular to a push-plate type nail feeder. Background Technology

[0002] A screw feeder is a specialized screw supply device used in automated production. It automatically arranges, separates, and delivers screws to designated locations for further processing or assembly. Its core objective is to improve production efficiency and reduce the complexity of manual operation. It is widely used, especially in mass production, such as in electronics assembly, automobile manufacturing, and home appliance production.

[0003] In the prior art, the conveying of screws is mostly achieved by using a vibratory feeder structure. For example, Chinese utility model patent with publication number CN220744493U disclosed a nail feeding mechanism on April 9, 2024, which uses a vibratory feeder as a feeding device to convey screws to the discharge port through the vibration of the vibratory feeder.

[0004] However, the above-mentioned method of using a vibratory feeder takes up a lot of space and is also expensive. Utility Model Content

[0005] In view of at least one of the above technical problems, the present invention provides a push-plate type nail feeder, which adopts structural improvements to reduce the cost of the nail feeder.

[0006] According to a first aspect of the present invention, a pusher-type nail feeding machine is provided, comprising: a feeding mechanism including a storage hopper and a pushing component;

[0007] A feeding mechanism, connected to the pushing assembly, includes an inclined linear material channel, the pushing assembly being used to push screws into the linear material channel;

[0008] The material distribution mechanism is connected to the output end of the linear material channel and includes a nail dropping channel and a material distribution component. At least two nail dropping channels are provided, and the material distribution component is used to feed the screws output from the linear material channel into the designated nail dropping channels.

[0009] The material pushing assembly includes a retaining wall arranged parallel to the straight material channel, a push plate that is attached to the retaining wall and can move along the vertical direction of the retaining wall, and a material pushing drive for pushing the push plate to move up and down. The lowest point of the push plate's movement stroke is at the bottom of the storage hopper, and the highest point of the push plate's movement stroke is not lower than the top of the retaining wall. The top of the push plate has an inclined wall arranged in the direction of sliding down the retaining wall.

[0010] In some embodiments of this utility model, the straight material channel is inclined toward the direction in which the material distribution mechanism slides, and the straight material channel also has a material full detection component.

[0011] In some embodiments of this utility model, the top of the straight material channel also has a blowing assembly disposed toward the storage hopper.

[0012] In some embodiments of this utility model, the blowing assembly includes an orifice plate facing the top of a straight material channel, an air chamber fitted and connected to the orifice plate, and a first air nozzle connected to the air chamber. The first air nozzle is connected to an air source, and the orifice plate has air holes facing the straight material channel.

[0013] In some embodiments of this utility model, the feeding mechanism further includes a vibration component, which is fixed to the side of the retaining wall away from the storage hopper and connected to the linear material channel for driving the vibration of the linear material channel.

[0014] In some embodiments of this utility model, the material distribution assembly includes a material distribution block and a material distribution cylinder for driving the material distribution block to move laterally. The material distribution block has a material dropping channel for accommodating a single nail. The material distribution cylinder is used to drive the material distribution block so that the material dropping channel is aligned with the nail dropping channel.

[0015] In some embodiments of this utility model, two drop channels are provided, and the two ends of the stroke of the distribution cylinder meet the dimensional requirements that the drop channel is aligned with the two drop channels respectively.

[0016] In some embodiments of this utility model, the top of the material distribution block is further provided with a stop assembly, the stop assembly including a baffle for covering or exposing the material drop channel, and the end of the baffle facing the straight material channel is further provided with a socket for inserting a stud.

[0017] In some embodiments of this utility model, the stop assembly further includes a longitudinal groove, a cover plate, and a stop cylinder for driving the material distribution block on the material distribution block. The cover plate has an arc-shaped groove, and the baffle is movable relative to the longitudinal groove. The baffle is slidably connected to the arc-shaped groove. The arc-shaped groove is configured such that when the stop cylinder drives the material distribution block to move to the middle position, the baffle covers the material dropping channel; when the material distribution block moves to the two sides, the baffle exposes the material dropping channel, causing the screw to fall into the screw dropping channel.

[0018] In some embodiments of this utility model, a second air nozzle is also connected to the nail dropping channel, the nail dropping channel has an air blowing hole that is inclined toward the direction in which the screw falls, and the second air nozzle communicates with the air blowing hole.

[0019] The beneficial effects of this utility model are as follows: This utility model realizes the feeding of screws in the storage hopper by lifting and lowering the push plate. Compared with the existing technology of using a vibratory plate, it not only occupies less space but also saves costs. Furthermore, the setting of the material distribution mechanism allows screws to select different nail drop channels, improving the applicability of the nail feeding machine.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0035] like Figures 1 to 10 The push-plate type nail feeder shown includes a feeding mechanism 1, a feeding mechanism 2, and a distributing mechanism 3, as detailed below. Figure 1 As shown, the feeding mechanism 1 includes a storage hopper 11 and a pushing assembly 12. The storage hopper 11 is used to hold screws, and the pushing assembly 12 is used to push the screws in the storage hopper 11 towards the desired direction. The feeding mechanism 2 is connected to the pushing assembly 12 and includes an inclined linear feed channel 21. The pushing assembly 12 is used to push the screws into the linear feed channel 21. In this embodiment of the invention, the pushing assembly 12 feeds the screws into the linear feed channel 21 by lifting them. Because the linear feed channel 21 is inclined, as... Figure 1As shown, after the feeding assembly 12 feeds the screw into the linear feed channel 21, the screw can be conveyed to the dispensing mechanism 3 along the direction of the linear feed channel 21; please continue to refer to Figure 1 In an embodiment of this utility model, the material distribution mechanism 3 is connected to the output end of the straight material channel 21, and includes a nail dropping channel 31 and a material distribution component 32. The nail dropping channel 31 is provided with at least two, and the material distribution component 32 is used to feed the screws output from the straight material channel 21 into the set nail dropping channel 31.

[0036] Please refer to the details. Figure 2 The feeding assembly 12 includes a baffle wall 12a arranged parallel to the straight feed channel 21, a push plate 12b attached to the baffle wall 12a and movable along the vertical direction of the baffle wall 12a, and a feeding drive 12c for pushing the push plate 12b up and down. The lowest point of the push plate 12b's travel is at the bottom of the storage hopper 11, and the highest point of the push plate 12b's travel is not lower than the top of the baffle wall 12a. The top of the push plate 12b has an inclined wall 12b1 facing the sliding direction of the baffle wall 12a. Specifically, as shown... Figure 3 As shown, when the push plate 12b moves to the bottom, it is at the bottom of the storage hopper 11. At this time, under the action of gravity, the screws will accumulate on the top of the push plate 12b. As the push plate 12b rises, some of the screws will rise with the top of the push plate 12b. When it rises to the highest point, the screws will slide down into the straight material channel 21 under the action of the inclined wall 12b1.

[0037] In the above embodiment, the screws in the storage hopper 11 are fed by lifting the push plate 12b. Compared with the method of vibrating plate in the prior art, it not only occupies less space but also saves costs. Furthermore, the setting of the material distribution mechanism 3 allows the screws to select different nail drop channels 31, which improves the applicability of the nail feeding machine.

[0038] Optionally, such as Figure 4 As shown, the straight material channel 21 is inclined toward the direction in which the material distribution mechanism 3 slides down, and the straight material channel 21 also has a material full detection component 22. It should be noted that the material full detection component 22 can take many forms. For example, it can be that a laser is irradiated into the straight material channel 21, and whether the laser is blocked is used to determine whether the screws fill the straight material channel 21. If the laser is not blocked, it means that there are no screws in the storage hopper 11, and screws need to be replenished.

[0039] Optionally, to improve the reliability of the delivery screw, such as Figure 4 As shown, the top of the straight material channel 21 also has a blowing assembly 23 disposed towards the storage hopper 11. Please refer to [reference needed] for details. Figure 3When conveying screws, the width of the straight material channel 21 is slightly larger than the screw stud but smaller than the screw nut. Therefore, the screw moves laterally in a vertical position. During the movement from the push plate 12b towards the straight material channel 21, some screws may not extend into the straight material channel 21 but instead overlap horizontally above it. By blowing material, the screws that have overlapped on the straight material channel 21 can be blown into the storage hopper 11, improving the smoothness of the conveying. Of course, it should be noted that the structure of the blowing assembly 23 can be varied. For example, it can use high-pressure air blowing in a direction perpendicular to the straight material channel 21.

[0040] In some embodiments of this utility model, such as Figure 5 As shown, the blowing assembly 23 includes an orifice plate 23a facing the top of the straight material channel 21, an air chamber 23b connected to the orifice plate 23a, and a first air nozzle 23c connected to the air chamber 23b. The first air nozzle 23c is connected to an air source, and the orifice plate 23a has air holes facing the straight material channel 21. With this arrangement, after the first air nozzle 23c is connected to a high-pressure air source, the gas enters the air chamber 23b and is then blown out through the air holes on the orifice plate 23a. In this embodiment of the present invention, one air chamber 23b can correspond to multiple air holes on the orifice plate 23a, thereby reducing the number of first air nozzles 23c.

[0041] Optionally, such as Figure 6 As shown, the feeding mechanism 2 also includes a vibration component, which is fixed to the side of the retaining wall 12a away from the storage hopper 11 and connected to the linear material channel 21 to drive the vibration of the linear material channel 21. Vibration can improve the stability of the screw's movement in the linear material channel 21. It should be noted that the vibration component can take many forms, such as electromagnetic vibration or eccentric rotational vibration.

[0042] Optionally, such as Figure 7 and Figure 8 As shown, the material distribution assembly 32 includes a material distribution block 32a and a material distribution cylinder 32b for driving the material distribution block 32a to move laterally. The material distribution block 32a has a material dropping channel 32a1 for accommodating a single nail. The material distribution cylinder 32b drives the material distribution block 32a so that the material dropping channel 32a1 is aligned with the nail dropping channel 31. That is, in the initial state, the material dropping channel 32a1 is connected to the outlet of the straight material channel 21. After a single screw in the straight material channel 21 enters the material dropping channel 32a1, the material distribution cylinder 32b drives the screw in the material dropping channel 32a1 to align with the nail dropping channel 31, thereby realizing the nail entering the corresponding nail dropping channel 31.

[0043] In some embodiments of this utility model, two nail-feeding channels 31 are provided, and the two ends of the stroke of the dispensing cylinder 32b meet the dimensional requirements of aligning the dispensing channel 32a1 with the two nail-feeding channels 31 respectively. With this arrangement, as... Figure 8 As shown, when the material distribution cylinder 32b moves to the leftmost end, it corresponds to the left-side nail dropping channel 31, and when it moves to the rightmost end, it corresponds to the right-side nail dropping channel 31.

[0044] Optionally, such as Figure 8 As shown, the top of the material distribution block 32a also has a stop assembly 33, which includes a baffle 33a for covering or exposing the material drop channel 32a1. The end of the baffle 33a facing the straight material channel 21 also has a socket for inserting a stud. It should be noted that the baffle 33a can move in various ways, such as moving laterally on the material distribution block 32a or rotating to cover or expose the material drop channel 32a1. Here, exposure means allowing the screw in the straight material channel 21 to enter the material drop channel 32a1 on the material distribution block 32a, while blocking means preventing the screw from falling from the material drop channel 32a1. The size of the socket is adapted to the size of the straight material channel 21 so that the screw head overlaps the socket and the stud is vertically downward.

[0045] In some specific embodiments of this utility model, the stop assembly 33 further includes a longitudinal groove 32a2 disposed on the material distribution block 32a, a cover plate 33b, and a stop cylinder 33c that drives the material distribution block 32a. The cover plate 33b has an arc-shaped groove 33b1. The baffle 33a is relatively movable within the longitudinal groove 32a2. The baffle 33a is slidably connected within the arc-shaped groove 33b1. The arc-shaped groove 33b1 is configured such that when the stop cylinder 33c drives the material distribution block 32a to the middle position, the baffle 33a covers the material drop channel 32a1; when the material distribution block 32a moves to the sides, the baffle 33a exposes the material drop channel 32a1, causing the screw to fall into the screw drop channel 31. Figure 8 As shown, the arc-shaped groove 33b1 on the cover plate 33b is designed as an inverted arch structure. When the material distribution block 32a moves to the middle position, the baffle 33a is positioned closest to the material discharge channel 32a1 within the longitudinal groove 32a2, effectively blocking the material discharge channel 32a1. At this time, the screw cannot fall due to the obstruction of the baffle 33a. Since the baffle 33a is slidably connected to the arc-shaped groove 33b1, under the action of the arc-shaped groove 33b1, when moving to the left or right end, because both sides of the arc-shaped groove 33b1 extend away from the material discharge channel 32a1, it pulls the baffle 33a away from the material discharge channel 32a1, thereby opening the material discharge channel 32a1. Of course, it should be noted here that... Figure 8As shown, the cover plate 33b also has a slotted hole. When the material distribution block 32a moves to the leftmost or rightmost end, the baffle 33a retracts, and the screw falls into the material discharge channel 32a1.

[0046] Optionally, such as Figure 9 and Figure 10 As shown, a second air nozzle 31a is also connected to the nail dropping channel 31. The nail dropping channel 31 has an air blowing hole 31b inclined towards the direction in which the screw falls, and the second air nozzle 31a communicates with the air blowing hole 31b. In an embodiment of this utility model, the nail dropping channel 31 can be connected to a flexible hose to directly transport the screws falling from the nail dropping channel 31 to the required location. By blowing air into the air blowing hole 31b through the second air nozzle 31a, the screws can be driven to move within the flexible hose, further improving the efficiency and reliability of the conveying process.

[0047] Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
