[0001] The utility model relates to the technical field of pin taking, in particular to an automatic pin feeding device. Background Art
[0002] A pin is a commonly used fastener, usually used to connect and fix two or more parts. A pin is usually made of metal, has a cylindrical or conical head, and a shaft and a sharp portion formed at the other end. In the field of industrial manufacturing, pins are used in a wide range of areas and in large quantities. Since a large number of pins are piled together when stored, their sharp portions face in all directions, making it very inconvenient to take them out.
[0003] A Chinese patent with announcement number CN219193636U discloses a pin feeding device, which arranges the pins and reduces the time and energy spent by workers when taking them out by placing the pins on the inner wall of a placing groove, guiding the pins into the limiting grooves through a conduit, and pushing the pins out of the limiting grooves through an air pump. However, the inventor found in the process of implementing the patent that the number of pins put into the limiting grooves will be the same as the number of pins discharged each time, and these pins will move as a whole to the end of the cross bar when moving from the cross bar, causing excess pins to be discharged. Utility Model Content
[0004] In view of the deficiencies in the prior art, the utility model provides an automatic pin feeding device, which solves the problem in the prior art that when the messy pins in the storage box are discharged, the corresponding number of pins cannot be discharged according to the quantity required by the user.

DETAILED DESCRIPTION
[0019] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.
[0020] like Figure 1—4, an embodiment of the utility model proposes an automatic pin feeding device, including a transmission box 1 and a material transporting plate 8, the transmission box 1 is vertically erected on the ground through a support frame 2, a channel 3 for the pin to pass through is opened in the length direction of the transmission box 1, a material storage box 4 is provided at the end of the transmission box 1 away from the support frame 2, the channel 3 of the transmission box 1 is connected with the material storage box 4, a mounting groove is opened in the channel 3 of the transmission box 1, a connecting plate 5 is slidingly provided in the mounting groove, a first partition plate 6 and a second partition plate 7 are alternately provided on the side wall of the connecting plate 5, a driving component for driving the connecting plate 5 to move horizontally is provided on the side wall of the transmission box 1, the material transporting plate 8 is obliquely supported on the ground by a support column 9, a material guide groove 10 is opened on the top of the material transporting plate 8, the high end of the material transporting plate 8 is located directly below the channel 3 of the transmission box 1, an L-shaped baffle 11 is fixedly provided at the lower end of the material transporting plate 8, and a through hole 12 is opened at the end of the L-shaped baffle 11 close to the material transporting plate 8. Specifically, in the present embodiment, the spacing between the first partition plate 6 and the second partition plate 7 is the length of the pin. When using the present device, the pin is put into the storage box 4, and the pin enters the channel 3 of the transmission box 1 through the storage box 4. At this time, the first partition plate 6 closes the channel 3, and the driving component is started. The driving component drives the connecting plate 5 to move horizontally. At this time, the first partition plate 6 follows the connecting plate 5 to move and finally opens the channel 3, so that the pin on the top of the first partition plate 6 falls off, and at this time, the second partition plate 7 closes the channel 3, and the pin will fall on the top of the second partition plate 7. At this time, the driving component is started again to drive the connecting plate 5 to move, and the first partition plate 6 moves in the direction of the closed channel 3 (i.e., moves to the right). In the present embodiment, A protrusion with a triangular cross-section is provided at the end of a partition 6, which is convenient for inserting between two pins. At this time, the second partition 7 will move in the direction of opening the channel 3 until the first partition 6 closes the channel 3 again. The pin at the top of the second partition 7 falls from the channel 3 into the guide groove 10 of the material transport plate 8 due to the removal of the second partition 7 at the bottom, and finally slides to the end, and is discharged from the through hole 12 on the baffle 11 to the position to be loaded. The driving assembly drives the reciprocating movement of the connecting plate 5, so that the pins entering the channel 3 of the transmission box 1 are discharged one by one, and one is discharged when it is needed. There will be no situation where too many pins are discharged and cause pin accumulation, so that workers can accurately obtain pins and improve efficiency.
[0021] like Figure 3—4 Further, the driving assembly includes: a first hydraulic cylinder 13 and a push plate 14. The first hydraulic cylinder 13 is fixedly arranged on the top of the support frame 2, and the push plate 14 is arranged horizontally. One end of the push plate 14 is fixedly connected to the connecting plate 5, and the other end of the push plate 14 is fixedly connected to the output end of the first hydraulic cylinder 13 after passing through the installation slot, and the push plate 14 is slidably connected to the transmission box 1. When the control pin falls, the first hydraulic cylinder 13 is started, and the first hydraulic cylinder 13 pushes the push plate 14 to move horizontally, thereby driving the connecting plate 5 located in the installation slot to move horizontally, so that the first partition 6 and the second partition 7 open and close the channel 3 respectively, that is, the pins located in the channel 3 are discharged from the channel 3 one by one. Preferably, a corresponding control pedal can be set to control the first hydraulic cylinder 13, so that the worker can control the extension and retraction of the first hydraulic cylinder 13 by stepping on the pedal.
[0022] Furthermore, the slot width of the guide slot 10 of the material transport plate 8 is the same as the diameter of the shaft of the pin. When the pin falls from the channel 3 and lands on the material transport plate 8, the head of the pin will be stuck on the top of the guide slot 10, and the shaft and sharp part of the pin enter the guide slot 10. The entire pin slides along the guide slot 10 until it slides to the end of the material transport plate 8 and is blocked by the baffle 11 and discharged through the through hole 12. In this process, whether the pin with the head facing down or the sharp part facing down falls on the guide slot 10, due to the restriction of the pin head by the top of the guide slot 10, the end of the pin with the sharp part faces down, thereby achieving the correction effect of the direction of the sharp part of the pin. Preferably, in order to facilitate the sharp part of the pin to enter the guide slot 10, the width of the guide slot 10 is slightly larger than the diameter of the pin shaft and smaller than the diameter of the pin head.
[0023] like Figure 1 and 4 As shown, further, it also includes a second hydraulic cylinder 15, which is fixedly arranged on the side wall of the transmission box 1, and the output end of the second hydraulic cylinder 15 is vertically upward and fixedly connected to the bottom of the storage box 4, and one end of the transmission box 1 passes through the storage box 4 and is slidably set with the storage box 4. A number of pins are stored in the storage box 4, and the accommodating space of the channel 3 is limited. It is not possible to allow all the pins in the storage box 4 to enter the channel 3 in time, which will cause the pins to pile up and intertwine with each other, and it is difficult to fall into the channel 3 later. At this time, the storage box 4 is driven to rise or fall by the second hydraulic cylinder 15, so that the intertwined state between the pins in the storage box 4 is destroyed, so that the pins are easier to enter the channel 3, and through the relative movement of the storage box 4 and the top of the transmission box 1, when the pins are not required to enter the channel 3, the horizontal height of the top of the transmission box 1 is higher than the horizontal height of the pins in the storage box 4.
[0024] like Figure 1As shown in FIG. 2 , further, a feed hopper 16 is fixedly provided on the top of the transmission box 1, and an arc-shaped depression is provided on the top of the feed hopper 16, which is connected to the channel 3 of the transmission box 1. In order to make it easier for the pin to enter the channel 3 of the transmission box 1, a flared feed hopper 16 is provided on the top of the transmission box 1, so that the pin in the storage box 4 can enter the feed hopper 16 more easily, and then the pin is guided by the feed hopper 16 to fall into the channel 3 of the transmission box 1.
[0025] like Figure 2 and 5 As shown, further, it also includes a limit block 17, and the limit block 17 is two pieces, and the two limit blocks 17 are symmetrically arranged at both ends of the through hole 12 on the baffle 11. In this embodiment, the two limit blocks 17 and the baffle 11 are detachably arranged, and can be threadedly removed or fixed to the top of the baffle 11 by glue. The limit block 17 is connected to the material transport plate 8, so that after the screw slides onto the baffle 11, it will not be discharged from the through hole 12 but stuck between the two limit blocks 17. At this time, the worker can manually take the pin and place the pin at the desired position.
[0026] Furthermore, a vibration mechanism is provided on the feed hopper 16. The vibration mechanism generates vibration to prevent the pins from getting stuck after entering the feed hopper 16, and the pins accumulated in the feed hopper 16 can fall into the channel 3 through vibration. Preferably, a groove can be formed on the side wall of the feed hopper 16, and the vibration mechanism can be embedded in the groove on the side wall of the feed hopper 16 to prevent it from affecting the pins in the storage box 4.
[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
