Description

Technical Field

[0001] This utility model relates to the field of screw anti-slip technology, specifically a screw dispensing machine. Background Technology

[0002] The working principle of a screw dispensing machine is mainly based on fluid mechanics and mechanical control principles. The glue is stored in a specific glue cartridge or valve, and is pushed to the dispensing needle by a pneumatic drive or mechanical device such as a plunger pump or gear pump.

[0003] A search revealed a utility model patent with Chinese patent publication number CN213194352U, which discloses an automatic dispensing machine for anti-slip screws. The machine includes a housing and anti-slip screws. A belt drive mechanism is installed inside the housing. A top plate is fixedly installed on the housing via two support rods. Multiple mounting plates are installed on the top plate via a telescopic mechanism. Each mounting plate has two dispensing boxes fixedly installed via two spring rods. Each dispensing box has two glue storage boxes and an electromagnet fixedly installed.

[0004] The aforementioned device requires the screw to be placed in a designated slot before adhesive can be applied, and the screw must be removed after processing. This process is time-consuming, cannot achieve continuous processing, and is not conducive to improving work efficiency, thus leaving room for improvement. Utility Model Content

[0005] The purpose of this invention is to provide a screw dispensing machine to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a screw dispensing machine, comprising a base and a support frame, the base and the support frame being at the same level, with the support frame located at one end of the base; a dispensing assembly and a conveying assembly being installed on the top of the base, the dispensing assembly being located on one side of the conveying assembly; the conveying assembly comprising a mounting base fixedly connected to the outer wall of the top of the base, two mounting brackets fixedly connected to the top of the mounting base, the two mounting brackets forming a complete circular groove; a chuck being rotatably connected to the outer wall of the top of the mounting base via a bearing, the chuck being positioned exactly within the circular groove; four U-shaped slots being provided on the outer circumference of the chuck; a motor being fixedly installed on the outer wall of the top of the mounting base, an incomplete gear being fixedly connected to the output end of the motor; a gear one meshing with the incomplete gear being coaxially fixed to the rotating shaft of the chuck, the number of teeth of the gear one being four times that of the incomplete gear.

[0007] As a further preferred embodiment of this technical solution, a push plate is rotatably connected to the top outer wall of one of the mounting brackets via a bearing. A gear two that meshes with an incomplete gear is coaxially fixed outside the rotating shaft of the push plate. The number of teeth of the gear two is the same as the number of teeth of the incomplete gear. A collecting assembly is installed inside the support bracket. The collecting assembly includes a limiting slide groove opened on the outer wall of one end of the support bracket. A receiving bracket is slidably inserted inside the limiting slide groove. The receiving bracket has multiple horizontally arranged receiving slots inside, and one of the receiving slots is connected to two mounting brackets with a gap.

[0008] This device enables continuous screw dispensing, allowing operators to simply feed screws continuously, eliminating the need to remove them and improving processing efficiency. The screw is pushed into the gap between two mounting brackets, then enters a chuck hole. The motor output rotates one revolution, causing the top incomplete gear to rotate a quarter revolution. After two such cycles, the screw is processed. Then, the first gear rotates another quarter revolution, moving the screw to the other gap between the two mounting brackets. The motor output's incomplete gear then meshes with a second gear, causing the second gear and its top push plate to rotate one revolution. The push plate then pushes the screw out of the gap between the two mounting brackets, where it is neatly stored in a receiving slot. Operators simply need to continuously feed screws.

[0009] As a further preferred embodiment of this technical solution, a horizontally arranged extension plate is fixedly connected to one side of the outer wall of the support frame, and a positioning rod is slidably inserted inside the extension plate. Multiple locking holes are opened on one side of the outer wall of the receiving frame, and the multiple locking holes are respectively opposite to the positions of multiple receiving grooves. The positioning rod is inserted into one of the locking holes, and a spring is sleeved on the outside of the positioning rod. The two ends of the spring are fixedly connected to the end of the positioning rod and the extension plate, respectively.

[0010] As a further preferred embodiment of this technical solution, the dispensing assembly includes a pneumatic slider four fixedly installed on one end of the outer wall of the top of the base, and the pneumatic slider four is set in a vertical position. A drill is fixedly installed on the movable end of the pneumatic slider four, and the wrench at the end of the drill is aligned with one of the slots of the chuck.

[0011] As a further preferred embodiment of this technical solution, a bracket is fixedly connected to one side of the top outer wall of the base, and a vertically arranged pneumatic slider one is fixedly installed on the top of the bracket. A horizontally arranged pneumatic slider two is fixedly installed on the movable end of the pneumatic slider one, and an inclined pneumatic slider three is fixedly installed on the movable end of the pneumatic slider two. A glue dispensing cylinder is fixedly installed on the movable end of the pneumatic slider three, and the glue dispensing port of the glue dispensing cylinder is located on one side of the drilling machine.

[0012] By controlling pneumatic slider two, the glue outlet of the glue dispensing tube is positioned precisely on the side of the screw. Since pneumatic slider three is tilted, the glue dispensing tube can adapt to the angle of the screw end. By controlling pneumatic slider one, the glue dispensing tube can fully apply glue to the threaded part of the screw. During this process, by controlling pneumatic slider four, the drill moves downward, and the wrench fixed at its rotating end will be inserted into the hole at the top of the screw. With the control of the drill, the screw can start to rotate, ensuring that the glue is distributed sufficiently.

[0013] As a further preferred embodiment of this technical solution, the top outer wall of the mounting base has two placement slots, and each of the two placement slots contains a collection box, with the two collection boxes located at the bottom of the two slots of the chuck.

[0014] As a further preferred embodiment of this technical solution, the bottom outer wall of the support frame is provided with a rubber anti-slip pad.

[0015] This utility model provides a screw dispensing machine, which has the following beneficial effects:

[0016] (1) By setting up a conveying component and a collecting component, this utility model can realize continuous screw dispensing operation. The operator only needs to continuously put in the screw, which can save the process of removing the screw and improve the processing efficiency of the device. The screw is pushed into the gap between the two mounting brackets and then enters the chuck hole. The motor output end is controlled to rotate one revolution. The incomplete gear at the top of the motor drives the first gear to rotate one quarter revolution through meshing. After this process is repeated twice, the screw can be processed. Then the first gear is driven to rotate one quarter revolution, and the screw is moved to the other gap between the two mounting brackets. The incomplete gear at the motor output end then meshes with the second gear, which then drives the second gear and its top push plate to rotate one revolution. The push plate can push the screw out of the gap between the two mounting brackets and then into the receiving groove to be neatly stored. The operator only needs to continuously put in the screw.

[0017] (2) By setting up a dispensing assembly, the dispensing nozzle of the dispensing tube is positioned on the side of the screw by controlling the pneumatic slider two. Since the pneumatic slider three is tilted, the dispensing tube can adapt to the angle of the screw end. By controlling the pneumatic slider one, the dispensing tube can be used to fully dispense glue to the threaded part of the screw. During this period, the drill is moved down by controlling the pneumatic slider four, and the wrench fixed at its rotating end will be inserted into the hole at the top of the screw. With the control of the drill, the screw can start to rotate, so that the glue is distributed sufficiently. Attached Figure Description

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] This utility model provides a technical solution: such as Figure 1 , Figure 2 and Figure 3 As shown, in this embodiment, a screw dispensing machine includes a base 1 and a support frame 2. The base 1 and the support frame 2 are at the same level, and the support frame 2 is located at one end of the base 1. A dispensing component 4 and a conveying component 5 are installed on the top of the base 1. The dispensing component 4 is located on one side of the conveying component 5. The conveying component 5 includes a mounting base 501 fixedly connected to the top outer wall of the base 1. Two mounting brackets 502 are fixedly connected to the top of the mounting base 501. The two mounting brackets 502 form a complete circular groove. A chuck 503 is rotatably connected to the top outer wall of the mounting base 501 through a bearing. The chuck 503 is exactly in the circular groove. Four U-shaped slots are provided on the outer circumference of the chuck 503. A motor 504 is fixedly installed on the top outer wall of the mounting base 501. An incomplete gear is fixedly connected to the output end of the motor 504. A gear 505 that meshes with the incomplete gear is coaxially fixed to the rotating shaft of the chuck 503. The number of teeth of the gear 505 is four times that of the incomplete gear.

[0025] One of the mounting brackets 502 has a push plate 507 rotatably connected to its top outer wall via a bearing. A gear 506 that meshes with an incomplete gear is coaxially fixed to the outside of the rotating shaft of the push plate 507. The number of teeth of the gear 506 is the same as the number of teeth of the incomplete gear. A collection component 6 is installed inside the support frame 2. The collection component 6 includes a limiting slide groove 601 opened on the outer wall of one end of the support frame 2. A receiving frame 602 is slidably inserted inside the limiting slide groove 601. A plurality of horizontally arranged receiving slots 603 are opened inside the receiving frame 602. One of the receiving slots 603 is connected to the two mounting brackets 502 with a gap.

[0026] The screw is pushed into the gap between the two mounting brackets 502, and then enters a chuck hole in the chuck 503. The output end of the motor 504 rotates one revolution, and the incomplete gear at its top meshes with the gear 505 to rotate one-quarter revolution. After this process is repeated twice, the screw can be processed. Then, the gear 505 is driven to rotate one-quarter revolution, and the screw is moved to the other gap between the two mounting brackets 502. The incomplete gear at the output end of the motor 504 then meshes with the gear 506, which then rotates the gear 506 and its top push plate 507 one revolution. The push plate 507 pushes the screw out of the gap between the two mounting brackets 502 and into the receiving groove 603 for neat storage. The operator only needs to continuously place the screw.

[0027] like Figure 2 and Figure 4 As shown, a horizontally arranged extension plate 604 is fixedly connected to one side of the outer wall of the support frame 2. A positioning rod 605 is slidably inserted into the extension plate 604. Multiple locking holes are opened on one side of the outer wall of the receiving frame 602, and the multiple locking holes are respectively opposite to the positions of multiple receiving grooves 603. The positioning rod 605 is inserted into one of the locking holes. A spring 606 is sleeved on the outside of the positioning rod 605. The two ends of the spring 606 are fixedly connected to the end of the positioning rod 605 and the extension plate 604, respectively.

[0028] When one of the receiving slots 603 of the receiving bracket 602 is full, simply pull the positioning rod 605 outward, and the spring 606 will also be stretched and lengthened. After the positioning rod 605 is disengaged from the inside of the receiving bracket 602, the receiving bracket 602 can be adjusted along the limiting slide 601 until the empty receiving slot 603 is aligned with the gap between the two mounting brackets 502. Finally, release the positioning rod 605, and the spring 606 will drive the positioning rod 605 to insert into the receiving bracket 602. This allows for quick replacement, and the neat arrangement of screws ensures that the screws can be easily picked up and moved.

[0029] like Figure 1As shown in Figure 2, the dispensing assembly 4 includes a pneumatic slider 405 fixedly installed on one end of the top outer wall of the base 1, and the pneumatic slider 405 is set in a vertical position. A drill 406 is fixedly installed on the movable end of the pneumatic slider 405, and the wrench at the end of the drill 406 is directly opposite one of the slots of the chuck 503.

[0030] A bracket is fixedly connected to one side of the top outer wall of the base 1, and a vertically arranged pneumatic slider 401 is fixedly installed on the top of the bracket. A horizontally arranged pneumatic slider 402 is fixedly installed at the movable end of the pneumatic slider 401. An inclined pneumatic slider 403 is fixedly installed at the movable end of the pneumatic slider 402. A glue dispensing cylinder 404 is fixedly installed at the movable end of the pneumatic slider 403. The glue dispensing port of the glue dispensing cylinder 404 is located on one side of the drilling rig 406.

[0031] By controlling pneumatic slider 2 402, the glue outlet of glue dispensing cylinder 404 is positioned precisely on the side of the screw. Since pneumatic slider 3 403 is tilted, glue dispensing cylinder 404 can adapt to the angle of the screw end. By controlling pneumatic slider 1 401, glue dispensing cylinder 404 can fully apply glue to the threaded part of the screw. During this process, by controlling pneumatic slider 405, drilling machine 406 is moved downward, and the wrench fixed at its rotating end will be inserted into the hole at the top of the screw. With the control of drilling machine 406, the screw can start to rotate, ensuring that the glue is distributed sufficiently.

[0032] like Figure 1 As shown in Figure 2, the top outer wall of the mounting base 501 has two placement slots, and each of the two placement slots contains a collection box 3. The two collection boxes 3 are located at the bottom of the two slots of the chuck 503. If too much glue is sprayed, the collection box 3 can collect it, which helps to save resources.

[0033] like Figure 1 As shown in Figure 2, the bottom outer wall of the support frame 2 is provided with a rubber anti-slip pad, which helps to increase the static friction between the support frame 2 and the ground, thereby ensuring that the screws will not be displaced randomly when they are collected.

[0034] This utility model provides a screw dispensing machine, the specific working principle of which is as follows:

[0035] When the device is working, by controlling pneumatic slider two 402, the glue outlet of glue dispensing cylinder 404 is positioned precisely on the side of the screw. Because pneumatic slider three 403 is tilted, glue dispensing cylinder 404 can adapt to the angle of the screw end. By controlling pneumatic slider one 401, glue dispensing cylinder 404 can fully apply glue to the threaded portion of the screw. During this process, by controlling pneumatic slider four 405, the drill 406 is moved downwards, and the wrench fixed at its rotating end is inserted into the hole at the top of the screw. With the control of drill 406, the screw begins to rotate, ensuring sufficient glue distribution. The screw is pushed into the gap between the two mounting brackets 502, and then into a chuck hole in chuck 503. The output end of motor 504 rotates one revolution, and its top incomplete gear, through meshing, drives gear one 505 to rotate a quarter revolution. After this process is repeated twice, the screw is processed. Then, gear one 505 is driven to rotate another quarter revolution, and the screw is moved... The screw is moved to the other gap between the two mounting brackets 502. The incomplete gear at the output end of the motor 504 then meshes with the second gear 506, which in turn drives the second gear 506 and its top push plate 507 to rotate one revolution. The push plate 507 pushes the screw out of the gap between the two mounting brackets 502 and into the receiving groove 603 for neat storage. The operator only needs to keep placing the screw. When one of the receiving grooves 603 of the receiving bracket 602 is full, the positioning rod 605 is pulled outward, and the spring 606 is also stretched. After the positioning rod 605 is disengaged from the inside of the receiving bracket 602, the receiving bracket 602 can be adjusted along the limiting slide groove 601 until the empty receiving groove 603 is aligned with the gap between the two mounting brackets 502. Finally, the positioning rod 605 is released, and the spring 606 will drive the positioning rod 605 to insert into the receiving bracket 602. This allows for quick replacement, and the neat arrangement of the screws ensures that the screws can be easily picked up and moved.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
