Description

Technical Field

[0001] This utility model relates to the field of hardware processing, and in particular to a workpiece feeding device. Background Technology

[0002] In the mass production of small hardware parts such as screws and bolts, multi-station workflow is one of the core production links, requiring the sequential completion of processes such as raw material forming, thread processing, and surface plating. However, these hardware parts are generally characterized by their small size and heterogeneous structure—for example, the diameter of the bolt head and shank differs significantly, and the screw head has a Phillips head / slotted head or an internal hexagonal structure, making it difficult to adapt to traditional workstation transfer solutions. Existing automated conveying equipment is prone to parts stacking and jamming during transport, making it impossible to achieve orderly transport of individual parts; if manual transfer is relied upon, not only are labor costs high and efficiency low, but it is also prone to damage to parts due to operational errors. Utility Model Content

[0003] To improve the convenience of transferring hardware workpieces, this utility model provides a workpiece loading device.

[0004] This utility model provides a technical solution that adopts the following approach:

[0005] A workpiece feeding device includes a vibrating feeding plate, a conveying channel, a receiving part, and a driving component. The conveying channel has a locking groove, the width of which is smaller than the diameter of the largest part of the workpiece, thereby locking the workpiece. A vibrator is provided inside the conveying channel. The locking groove extends from the vibrating feeding plate to the receiving part. The driving component drives the receiving part to move from a position facing the discharge end of the conveying channel toward the feeding end of the next process. The receiving part has multiple receiving interfaces, which sequentially and cyclically move to a position facing the conveying channel.

[0006] The two ends of the snap-fit ​​groove point to the discharge end and the receiving end of the vibrating feeder, respectively. The workpiece at the discharge end of the vibrating feeder is vibrated onto the snap-fit ​​groove by the subsequent workpiece and the vibrating feeder. Then, it continues to move forward on the snap-fit ​​groove due to vibration and the push of the subsequent workpiece until it reaches the discharge end. The workpiece falls into the receiving end. The receiving end moves to the feeding end of the next process under the drive of the drive component, thereby completing the automated transfer of workpieces between adjacent process stations. The setting of multiple receiving ends can improve the efficiency of receiving workpieces and reduce the accumulation of workpieces on the snap-fit ​​groove.

[0007] Meanwhile, the workpiece is positioned in the snap-fit ​​groove by using the larger diameter part of the workpiece protruding from its outer periphery to snap into the groove. The remaining part of the workpiece hangs freely under its own weight. Vibration causes the workpiece to move forward on the conveyor channel, which replaces the direct clamping of the workpiece. This helps to improve conveying efficiency and the convenience of workpiece transfer, while also ensuring that multiple workpieces are in a consistent state after being conveyed.

[0008] Furthermore, the transmission channel, as the discharge extension of the vibrating feed plate, utilizes the motion inertia of the workpiece on the vibrating feed plate to drive the transmission of the workpiece, making the transmission of the workpiece more convenient.

[0009] Preferably, the conveying channel includes a horizontal section and an inclined section, the inclined section is located at one end of the horizontal section near the receiving section, and the length direction of the snap-fit ​​groove is consistent with the length direction of the horizontal section and the inclined section in which it is located.

[0010] The inclined section transitions between the horizontal section and the receiving section, and simultaneously accelerates the sliding of the workpiece at the connection between the horizontal section and the inclined section into the receiving section, making it easier for the workpiece to slide into the receiving section and improving the smoothness of the workpiece transfer between the conveyor channel and the receiving section.

[0011] Preferably, the receiving part is disc-shaped, and a plurality of receiving interfaces are evenly distributed around the outer periphery of the receiving part. The end of the inclined part points to the top of the receiving part, and the bottom end of the receiving part faces the feeding end of the next process.

[0012] The driving unit drives the receiving unit to rotate. A blocking member is provided on one side of the receiving unit. The blocking member has a blocking surface, which is an arc-shaped surface. The blocking surface extends from the top end of the receiving unit to the bottom end of the receiving unit, thereby preventing the workpiece in the receiving interface that has been loaded from separating from the receiving interface.

[0013] The rotating disc structure drives multiple receiving interfaces to rotate sequentially to the top of the receiving section for loading. After loading, the receiving interface rotates to a position directly opposite the blocking surface. The blocking surface prevents the workpiece from falling out of the receiving interface until the receiving interface rotates to the bottom of the receiving section, thus separating it from the blocking surface. Once the workpiece is no longer restricted by the blocking surface, it falls from the receiving interface to the loading end of the next process due to its own gravity, completing the workpiece transfer. The blocking component ensures the stable transfer of workpieces located between the loading and unloading ends of the receiving section.

[0014] The disc-shaped receiving part has circumferentially distributed receiving interfaces, which has a high space utilization rate and does not require a long space occupied by linear reciprocating motion; when rotating, each receiving interface is connected in a cycle, and the compact layout makes the unloading station more concentrated, saving the overall installation space of the equipment.

[0015] Preferably, the receiving part is provided with a plurality of positioning holes, which are located on the upper surface of the receiving part and are evenly distributed around the circumference of the receiving part. A recognizer is also provided on one side of the receiving part, which is used to identify the positioning holes. When the recognizer detects one of the positioning holes, one of the receiving interfaces is directly opposite the end of the snap-fit ​​groove.

[0016] When one of the positioning holes rotates to face the identifier so that the identifier can recognize the position of the positioning hole, one of the corresponding receiving interfaces rotates to face the end of the snap-fit ​​groove to facilitate material receiving. The setting of the identifier makes the receiving part more accurate, which is conducive to improving the automation and mechanization of the overall machine.

[0017] Preferably, the end of the horizontal portion near the inclined portion is provided with a rounded transition, and the rounded end of the horizontal portion is consistent with the inclination of the inclined portion.

[0018] The rounded transition between the horizontal and inclined sections allows workpieces on the horizontal section to be transferred more smoothly to the inclined section, which helps to improve the smoothness of workpiece transportation.

[0019] Preferably, the driving component includes a base, a rotating motor, a driving wheel, a driven wheel, a rotating shaft, and a transmission belt. The rotating motor is mounted on the base, and the driving shaft of the rotating motor is coaxially fixed to the driving wheel. The driven wheel and the receiving part are coaxially fixed to each other via the rotating shaft. The driving wheel and the driven wheel are driven by a transmission belt, and the rotating shaft is rotatably connected to the base.

[0020] The rotating motor starts and drives the driving wheel to rotate, which in turn drives the transmission belt to move, causing the driven wheel to rotate, which in turn drives the rotating shaft to rotate, and finally drives the receiving part to rotate. By setting the driving wheel, driven wheel and transmission belt, the driving structure of the receiving part is set on one side of the receiving part, reducing the number of parts that need to be set between the receiving part and the inclined part, and optimizing the structural space design between the two.

[0021] Preferably, the vibrator is an electromagnetic vibrator or a pneumatic vibrator.

[0022] In summary, this utility model has the following beneficial technical effects:

[0023] The two ends of the snap-fit ​​groove point to the discharge end and the receiving end of the vibrating feeder, respectively. The workpiece at the discharge end of the vibrating feeder is vibrated onto the snap-fit ​​groove by the subsequent workpiece and the vibrating feeder. Then, it continues to move forward on the snap-fit ​​groove due to vibration and the push of the subsequent workpiece until it reaches the discharge end. The workpiece falls into the receiving end. The receiving end moves to the feeding end of the next process under the drive of the drive component, thereby completing the automated transfer of workpieces between adjacent process stations. The setting of multiple receiving ends can improve the efficiency of receiving workpieces and reduce the accumulation of workpieces on the snap-fit ​​groove. Attached Figure Description

[0027] The following is in conjunction with the appendix Figure 1-2 The present invention will be described in further detail below.

[0028] This utility model discloses a workpiece feeding device.

[0029] Reference Figure 1 as well as Figure 2 A workpiece feeding device includes a vibrating feeding plate, a conveying channel 1, a receiving part 2, and a driving component. The conveying channel 1 has a locking groove 3, the width of which is smaller than the diameter of the largest part of the workpiece 4, thereby locking the workpiece 4. A vibrator 5 is provided inside the conveying channel 1. The locking groove 3 extends from the vibrating feeding plate to the receiving part 2. The driving component is used to drive the receiving part 2 to move from the position facing the discharge end of the conveying channel 1 toward the feeding end of the next process. The receiving part 2 has multiple receiving interfaces, which move sequentially to the position facing the conveying channel 1.

[0030] The two ends of the snap-fit ​​groove 3 point to the discharge end and the receiving interface of the vibrating feeder, respectively. The workpiece 4 at the discharge end of the vibrating feeder is vibrated onto the snap-fit ​​groove 3 by the subsequent workpiece 4 and the vibrating feeder. Then, it continues to move forward on the snap-fit ​​groove 3 under the vibration and the push of the subsequent workpiece 4 until it reaches the discharge end. The workpiece 4 falls into the receiving interface. The receiving interface moves to the feeding end of the next process under the drive of the drive component to unload the workpiece, thereby completing the automated transfer of the workpiece 4 between adjacent process stations. The setting of multiple receiving interfaces can improve the efficiency of receiving the workpiece 4 and reduce the accumulation of the workpiece 4 on the snap-fit ​​groove 3.

[0031] Meanwhile, the workpiece 4 is positioned on the snap-fit ​​groove 3 by using the larger diameter part of the protruding outer periphery of the workpiece 4 to snap into the snap-fit ​​groove 3. The remaining part of the workpiece 4 hangs freely under its own weight. Vibration causes the workpiece 4 to move forward on the conveying channel 1, which replaces the direct clamping of the workpiece 4. This is beneficial to improve the conveying efficiency and the convenience of transferring the workpiece 4. At the same time, it can keep multiple workpieces 4 in a consistent state after conveying.

[0032] Furthermore, the transmission channel, as the discharge extension of the vibrating feed plate, utilizes the motion inertia of the workpiece 4 on the vibrating feed plate to drive the transmission of the workpiece 4, making the transmission of the workpiece 4 more convenient.

[0033] Reference Figure 1 as well as Figure 2 In this embodiment, the conveying channel 1 includes a horizontal part 6 and an inclined part 7. The inclined part 7 is located at one end of the horizontal part 6 near the receiving part 2, and the length direction of the snap-fit ​​groove 3 is consistent with the length direction of the horizontal part 6 and the inclined part 7.

[0034] The inclined section 7 transitions the horizontal section 6 and the receiving section 2, and at the same time, it accelerates the sliding of the workpiece 4 to the receiving section 2 at the connection between the horizontal section 6 and the inclined section 7, making it easier for the workpiece 4 to slide into the receiving section 2, which helps to improve the smoothness of the transfer of the workpiece 4 between the conveying channel 1 and the receiving section 2.

[0035] Reference Figure 1 as well as Figure 2 In this embodiment, the receiving part 2 is disc-shaped, and multiple receiving interfaces are evenly distributed around the outer periphery of the receiving part 2. The end of the inclined part 7 points to the top of the receiving part 2, and the bottom of the receiving part 2 faces the feeding end of the next process.

[0036] The drive unit drives the receiving part 2 to rotate. A blocking member 8 is provided on one side of the receiving part 2. The blocking member 8 has a blocking surface, which is an arc-shaped surface. The blocking surface extends from the top end of the receiving part 2 to the bottom end of the receiving part 2, thereby restricting the separation of the workpiece 4 in the receiving interface that has been loaded from the receiving interface.

[0037] Through the rotating disc structure, the disc rotates, causing multiple receiving interfaces to rotate sequentially to the top of the receiving part 2 for loading. After loading, the receiving interface rotates to a position directly opposite the blocking surface. The blocking surface prevents the workpiece 4 inside the receiving interface from falling out of the receiving interface, until the receiving interface rotates to the bottom of the receiving part 2 and is thus misaligned with the blocking surface. After the workpiece 4 is no longer restricted by the blocking surface, it falls out of the receiving interface to the loading end of the next process due to its own gravity, thereby completing the transfer of the workpiece 4. The setting of the blocking component 8 ensures that the workpiece 4 located between the loading and unloading ends of the receiving part 2 can be transferred stably.

[0038] The disc-shaped receiving part has two circumferentially distributed receiving interfaces, which has a high space utilization rate and does not require a long space to be occupied by linear reciprocating motion; when rotating, each receiving interface is connected in a cycle, and the compact layout makes the unloading station more concentrated and saves the overall installation space of the equipment.

[0039] Reference Figure 1 as well as Figure 2 In this embodiment, the receiving part 2 is provided with a plurality of positioning holes 9. The positioning holes 9 are located on the upper surface of the receiving part 2. The plurality of positioning holes 9 are evenly distributed around the circumference of the receiving part 2. A recognizer 10 is also provided on one side of the receiving part 2. The recognizer 10 is used to recognize the positioning holes 9. When the recognizer 10 detects one of the positioning holes 9, one of the receiving interfaces is directly opposite the end of the snap-fit ​​groove 3.

[0040] When one of the positioning holes 9 is rotated to face the identifier 10 so that the identifier 10 can identify the position of the positioning hole 9, one of the corresponding receiving interfaces rotates to face the end of the snap-fit ​​groove 3 to facilitate receiving materials. The setting of the identifier 10 makes the receiving part 2 more accurate, which is conducive to improving the automation and mechanization of the overall machine.

[0041] In this embodiment, the identifier 10 is an infrared identifier 10. The identifier 10 emits infrared light to detect whether it is aligned with the positioning hole 9, and then feeds back to the controller connected to the drive component of the receiving part 2, thereby controlling the quantitative drive of the drive component.

[0042] Reference Figure 1 as well as Figure 2 In this embodiment, the end of the horizontal part 6 near the inclined part 7 is provided with an arc transition, and the arc end of the horizontal part 6 is consistent with the inclination of the inclined part 7.

[0043] The horizontal section 6 and the inclined section 7 are connected by a rounded arc, which allows the workpiece 4 on the horizontal section 6 to be transferred to the inclined section 7 more smoothly, which helps to improve the smoothness of the transport of the workpiece 4.

[0044] Reference Figure 1 as well as Figure 2 In this embodiment, the driving component includes a base 11, a rotating motor 12, a driving wheel, a driven wheel 13, a rotating shaft 14, and a transmission belt 15. The rotating motor 12 is mounted on the base 11. The driving shaft of the rotating motor 12 is coaxially fixed to the driving wheel. The driven wheel 13 is coaxially fixed to the receiving part 2 via the rotating shaft 14. The driving wheel and the driven wheel 13 are driven by a transmission belt. The rotating shaft 14 is rotatably connected to the base 11.

[0045] The rotating motor 12 starts and drives the driving wheel to rotate, which in turn drives the transmission belt 15 to move, causing the driven wheel 13 to rotate, which in turn drives the rotating shaft 14 to rotate, and finally drives the receiving part 2 to rotate. By setting the driving wheel, driven wheel 13 and transmission belt 15, the driving structure of the receiving part 2 is set on one side of the receiving part 2, reducing the number of parts that need to be set between the receiving part 2 and the inclined part 7, and optimizing the structural space design between the two.

[0046] Reference Figure 1 as well as Figure 2 In this embodiment, the vibrator 5 is an electromagnetic vibrator 5 or a pneumatic vibrator 5.

[0047] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
