Description

Technical Field

[0001] This utility model relates to the field of screw fastening technology, specifically a slide rail type screw feeding and fastening mechanism. Background Technology

[0002] A screw arranging machine neatly arranges screws and delivers them to a designated position for direct pickup by an electric screwdriver operator. This simplifies traditional screw fastening processes and improves production efficiency. Widely used in the electronics industry, screws move within a drum and fall into a hopper. Screws that do not enter the track are removed into the drum for the next cycle. The working speed is freely adjustable by changing the vibration intensity, ensuring the screws do not vibrate back and forth when reaching the pickup point, thus maintaining work efficiency.

[0003] Patent CN214922121U discloses a handheld automatic screw fastening machine. The machine features an automatic screw feeder hopper, a direct vibration automatic screw feeding mechanism, and a screw fullness sensor. When the hopper is full, the screw feeder automatically stops. A sliding rail screw dispensing mechanism completes the dispensing process and then automatically stops feeding. Screws are blown out from the dispensing section and fed to a screw head mechanism. A screw pushing mechanism pushes the screw head out of the mechanism. A screw feeding water cart automatically supplies screws, and the direct vibration automatic screw feeding mechanism is equipped with a screw fullness sensor. When the water cart is full, the screw feeding mechanism automatically stops.

[0004] In the above solution, when the screw is fed into the fastening station, the screw is prone to shifting during its descent, which affects the accuracy of fastening. Utility Model Content

[0005] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a slide rail type screw feeding and locking mechanism to solve the problems mentioned in the background art. This utility model has a novel structure. When the screw falls from the anti-tipping slide rail into the locking seat, it slides smoothly under the obstruction of the limiting plate. When it approaches the slot, it enters the locking seat through the auxiliary screw and keeps the screw vertically inside the locking seat to avoid the problem of displacement.

[0006] To achieve the above objectives, this utility model employs the following technical solution: a sliding rail type screw feeding and locking mechanism, comprising a base, a screw aligning feeder fixed to the top of the base, and a dispensing box provided at the outlet of the screw aligning feeder; an anti-tipping slide rail fixed to one side of the dispensing box of the screw aligning feeder, and an electric push rod fixed to the other side of the dispensing box of the screw aligning feeder; a locking assembly provided on the bottom surface of the base on the anti-tipping slide rail; the locking assembly comprising a mounting base fixed to the base, and a locking seat fixed to the bottom of the mounting base; a slot provided at the center of the locking seat, and an opening provided on the side of the slot facing the anti-tipping slide rail; screw blocks slidably mounted on the outer walls of both sides of the anti-tipping slide rail, and a limit plate rotatably mounted on the top of the screw blocks via a rotating shaft and a torsion spring; mounting grooves provided on both sides of the locking seat on the slot, and a guard bar provided in the mounting groove; and sensing optical fibers parallel to the anti-tipping slide rail fixed on both sides of the locking seat.

[0007] Furthermore, a vertical rail is fixed to the top of the base, and a slide is slidably mounted on the surface of the vertical rail. A cylinder is fixed to the top of the vertical rail, and the extended end of the cylinder is fixedly connected to the slide. A motor is fixed to the outside of the slide, and a drive rod is fixed to the output end of the motor.

[0008] Furthermore, the bottom of the drive rod is inserted into the mounting base, and a bit guide bearing is provided in the mounting base at the position where the drive rod is inserted. A magnet is provided on the top of the bit guide bearing, and the magnet and the bit guide bearing are wrapped around the surface of the drive rod.

[0009] Furthermore, the locking assembly also includes a screw rod. The screw rod is rotatably mounted on both outer walls of the anti-tipping slide rail via bearing seats, and the screw block is threaded onto the screw rod. A drive motor is installed on the outer wall of the anti-tipping slide rail at a position corresponding to one end of the screw rod.

[0010] Furthermore, a sliding groove is provided on the top inner wall of the mounting groove, and a sliding plate is slidably connected inside the sliding groove. A guardrail is rotatably installed on the bottom surface of the sliding plate, and a return spring is fixed between the inner wall of the sliding groove and the sliding plate.

[0011] Furthermore, a gear is installed at the rotatable connection between the barrier and the slide plate, and a toothed plate is fixed at the top of the mounting groove on one side of the slide groove, with the gear meshing with the toothed plate.

[0012] Furthermore, a baffle is fixed to the outer side of the sliding plate through the mounting groove, and one side of the screw block is in contact with the baffle. The anti-tipping slide rail is provided with a rotating groove at a position parallel to the mounting groove.

[0013] Furthermore, a top rod is fixed to the outer end of the locking seat, and the top rod is in pressure contact with the back of the limiting plate.

[0014] The beneficial effects of this utility model are:

[0015] 1. This utility model uses a screw feeder to feed screws. The feed box is equipped with a cam feeding mechanism. The screws are sorted by the feed box and then slide into the fastening assembly through the anti-tipping slide rail. After the optical fiber senses the material, the drive rod moves downward to fasten the screws. This reduces the original reciprocating screw picking method, reduces the reciprocating motion time, and effectively improves the efficiency of screw fastening.

[0016] 2. This utility model utilizes the threaded engagement of a screw block and a screw rod to slide along the outer wall of an anti-tipping slide rail. A limiting plate slides downwards along the inclined surface of the anti-tipping slide rail, and the screw descends smoothly and synchronously. When it approaches the locking seat, the back of the limiting plate contacts the top rod. Under the pressure of the top rod, the limiting plate rotates to both sides of the anti-tipping slide rail. At this point, the screw gradually enters the slot. As the screw block continues to move, it presses against the baffle plate, causing the baffle plate to move towards the rear end of the slide groove, compressing the return spring. As the baffle plate moves, the gear meshes with the toothed plate and rotates, causing the baffle plate to rotate from a vertical position to a horizontal position. During this process, the screw is pushed from the notch in the slot into the center of the slot. The screw is then kept vertically within the slot for subsequent locking.

[0017] 3. Compared with the prior art, when the screw falls from the anti-tipping slide rail into the locking seat, it slides smoothly under the obstruction of the limiting plate. When it approaches the slot, it enters the locking seat through the auxiliary screw, and keeps the screw vertically into the locking seat to avoid the problem of displacement.

[0027] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0028] Please see Figures 1 to 8This utility model provides a technical solution: a sliding rail type screw feeding and locking mechanism, including a base 1. A screw aligning feeder 2 is fixed to the top of the base 1, and a dispensing box is provided at the outlet of the screw aligning feeder 2. An anti-tipping slide rail 22 is fixed to one side of the dispensing box of the screw aligning feeder 2, and an electric push rod 21 is fixed to the other side of the dispensing box of the screw aligning feeder 2. A locking assembly 4 is provided on the bottom surface of the base 1 at the anti-tipping slide rail 22. The locking assembly 4 includes a mounting base 41, which is fixed to the base 1. A locking seat 43 is fixed to the bottom of the mounting base 41. A slot 415 is provided at the center of the locking seat 43, and the slot 415 has an opening on the side facing the anti-tipping slide rail 22. Screw blocks 46 are slidably installed on the outer walls of both sides of the anti-tipping slide rail 22, and the tops of the screw blocks 46 are connected by a rotating shaft. A limit plate 47 is installed with a torsion spring. The locking seat 43 is provided with mounting grooves 49 on both sides of the slot 415, and a baffle 417 is provided in the mounting groove 49. The locking seat 43 is fixed with sensing optical fibers 42 parallel to the anti-tipping slide rail 22 on both sides. The screw aligning feeder 2 in this solution is the prior art. It automatically feeds screws. When using the device, the screw aligning feeder 2 feeds the screws. The screws are sorted by the anti-tipping slide rail 22 and conveyed to the locking assembly 4. The locking assembly 4 limits the screws sliding down the anti-tipping slide rail 22 and pushes the screws into the slot 415. The screws are kept vertically inside the locking seat 43. The cylinder 31 drives the slide 32 to slide along the vertical rail 3. The drive rod 34 contacts the top of the screw. The motor 33 drives the drive rod 34 to rotate. The screw passes through the locking seat 43 for locking.

[0029] In this embodiment, a vertical rail 3 is fixed to the top of the base 1, and a slide 32 is slidably mounted on the surface of the vertical rail 3. A cylinder 31 is fixed to the top of the vertical rail 3, and the extended end of the cylinder 31 is fixedly connected to the slide 32. A motor 33 is fixed to the outside of the slide 32, and a drive rod 34 is fixed to the output end of the motor 33. The bottom of the drive rod 34 is inserted into the mounting base 41. A bit guide bearing 44 is provided in the mounting base 41 at the position corresponding to the insertion of the drive rod 34, and a magnet 45 is provided on the top of the bit guide bearing 44. The magnet 45 and the bit guide bearing 44 are wrapped around the surface of the drive rod 34. The screw is fed by a screw feeder. A cam sorting mechanism is provided inside the sorting box. The sorted screws are sorted by the sorting box. The sorted screws slide into the fastening assembly 4 through the anti-tipping slide rail 22. After the sensing fiber optic 42 senses the material, the drive rod 34 moves downward to fasten the screw. This reduces the original reciprocating screw picking method, reduces the reciprocating motion time, and effectively improves the efficiency of screw fastening.

[0030] In this embodiment, the locking assembly 4 further includes a screw 419. The screw 419 is rotatably mounted on the outer walls of both sides of the anti-tipping slide rail 22 via bearing seats, and a screw block 46 is threaded onto the screw 419. A drive motor is installed on the outer wall of the anti-tipping slide rail 22 at a position corresponding to one end of the screw 419. A slide groove 412 is formed on the top inner wall of the mounting groove 49, and a sliding plate 413 is slidably connected inside the slide groove 412. A guardrail 417 is rotatably mounted on the bottom surface of the sliding plate 413. The inner wall of the slide groove 412 and the sliding plate 413 are connected... A return spring 414 is fixed between 13. A gear 416 is installed at the rotatable connection between the guardrail 417 and the slide plate 413. A toothed plate 418 is fixed at the top of the mounting groove 49 on one side of the slide groove 412, and the gear 416 meshes with the toothed plate 418. A guardrail 410 is fixed to the outside of the slide plate 413 through the mounting groove 49, and one side of the screw block 46 is in contact with the guardrail 410. A rotating groove 411 is opened on the anti-tipping slide rail 22 parallel to the mounting groove 49. A top rod is fixed to the outer end of the locking seat 43. 48. The top rod 48 and the back of the limiting plate 47 are pressed into contact. After the screw is pushed into the anti-tipping slide rail 22, the limiting plate 47 is located at the uppermost end of the anti-tipping slide rail 22. The screw 419 is driven to rotate by the motor. The screw block 46 and the screw 419 are threaded together and slide along the outer wall of the anti-tipping slide rail 22. The limiting plate 47 slides down the slope of the anti-tipping slide rail 22. The screw also descends smoothly and synchronously. When it approaches the locking seat 43, the back of the limiting plate 47 contacts the top rod 48. Under the pressure of the top rod 48, the limiting plate 47 rotates to the anti-tipping slide rail 22. On both sides, the screw gradually enters the slot 415. As the screw block 46 continues to move, it presses against the baffle 410. The baffle 410 drives the slide plate 413 to move towards the rear end of the slide groove 412, compressing the return spring 414. As the slide plate 413 moves, the gear 416 meshes with the toothed plate 418 and rotates. The baffle 417 rotates from a vertical position to a horizontal position. During this process, the screw is pushed from the notch of the slot 415 into the center of the slot 415. Then, the screw is kept vertically placed inside the slot 415 to cooperate with the subsequent locking process.

[0031] When using the device, the screw is fed by a screw feeder. A cam-type feeding mechanism is installed inside the feeding box to sort the screws. The sorted screws slide into the locking assembly 4 via the anti-tipping slide rail 22. After the sensing fiber optic cable 42 senses the material, the drive rod 34 moves downward to lock the screw. After the screw is pushed onto the anti-tipping slide rail 22, the limiting plate 47 is at the uppermost end of the anti-tipping slide rail 22. The screw 419 is driven to rotate by the motor, and the screw block 46 slides along the outer wall of the anti-tipping slide rail 22 in threaded engagement with the screw 419. The limiting plate 47 slides downward along the inclined surface of the anti-tipping slide rail 22, and the screw also descends smoothly and synchronously. When it approaches the locking seat 43, the back of the limiting plate 47 contacts the top rod 48. Under the pressure of the top rod 48, the limiting plate 47 rotates to the anti-tipping position. On both sides of the slide rail 22, the screw gradually enters the slot 415. As the screw block 46 continues to move, it presses against the baffle 410. The baffle 410 drives the slide plate 413 to move towards the rear end of the slide groove 412, compressing the return spring 414. As the slide plate 413 moves, the gear 416 meshes with the toothed plate 418 and rotates. The baffle 417 rotates from a vertical position to a horizontal position. During this process, the screw is pushed from the notch of the slot 415 into the center of the slot 415. Then, the screw is kept vertically placed inside the slot 415. In conjunction with the subsequent locking process, the cylinder 31 drives the slide 32 to slide along the vertical rail 3. The drive rod 34 contacts the top of the screw. The motor 33 drives the drive rod 34 to rotate, and the screw passes through the locking seat 43 for locking.

It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.

[0033] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
