[0042] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0043] Reference Figure 1 This invention discloses an automatic nut feeding device, comprising: two vibrating feed discs 102 respectively connected to a discharge head 103 via a conveying pipe; two sets of slide rails 105 arranged horizontally and longitudinally below the discharge head 103; sliders 151 slidably mounted on the slide rails 105; a connecting plate 153 connected to the slider 151, and a connecting frame 154 connected to the lower end of the connecting plate 153; a receiving disc 104 rotatably mounted on the upper end of the connecting plate 153 and connected to a motor 201 mounted on the connecting frame 154; a first cylinder 202 also connected to the connecting frame 154; receiving columns 141 arranged in a preset manner on the upper end of the receiving disc 104, wherein the motor 201 drives the receiving disc 104 to rotate intermittently, so that one of the receiving columns 141 is located directly below the discharge port of one of the discharge heads 103.

[0044] This embodiment proposes an automatic nut feeding device to solve the problem of low efficiency in feeding screws onto equipment on industrial production lines. Specifically, through two vibrating feeders 102 and corresponding receiving trays 104, as well as corresponding components, nuts of different specifications can be stored separately, realizing the classified storage of nuts, or the two groups can work simultaneously. The vibrating feeders 102 and the conveying pipe are connected to the discharge head 103, so that the nuts can be automatically fed to the designated position without manual selection. The moving component on the workbench 101 can drive the receiving tray 104 to move, and the receiving column 14 on the receiving tray 104... The device can accurately receive nuts falling from the discharge head 103. Furthermore, the first cylinder 202 drives the slider 151 to move on the slide rail 105, causing it to move the receiving tray 104. When the receiving tray 104 is below the discharge head 103, and the receiving column 141 is directly below the discharge port of the discharge head 103, the discharge head 103 can discharge nuts separately, allowing for separate feeding when using nuts of different specifications. The motor 201 drives the receiving tray 104 to rotate intermittently, ensuring that only one receiving column 141 is directly below the discharge head 103 at a time, thus achieving precise feeding. When the receiving column 141 is full, the first cylinder 202 drives the receiving tray 104 to remove the nuts in batches and place them in the tool.

[0045] On the other hand, the two vibrating feeders 102 can also hold nuts of the same specification. When one receiving post 141 on the receiving plate 104 is located below one discharge head 103, the other receiving post 141 is also located below the other discharge head 103, so that two nuts can be placed at once, further improving the discharge efficiency.

[0046] The aforementioned structure reduces manual intervention in the automated feeding process, significantly improving the speed of screw feeding and the efficiency of the production line. The precise positioning and automatic selection mechanism reduces errors caused by human factors, such as selecting the wrong nut specification or position. This device also reduces the workload of workers, who only need to monitor the equipment's operation without performing repetitive physical labor. Multiple vibrating feeders 102 can work in coordination with the receiving tray 104, enabling the device to adapt to the feeding needs of nuts of different specifications, improving the flexibility and adaptability of the production line. Simultaneously, it reduces direct contact between workers and machinery, lowering the risk of workplace accidents.

[0047] In one embodiment of this application, a workbench 101 is further included; the workbench 101 is provided with a through hole; the slide rail 105, the slider 151 and the connecting plate 153 are disposed at the upper end of the through hole; the connecting frame 154 extends to the lower end of the through hole; a rotating shaft 142 is provided through the connecting plate 153; the motor 201 is connected to the receiving tray 104 through the rotating shaft 142. The workbench 101 separates the receiving tray 104 and its corresponding upper and lower portions. The connecting plate 153 is connected to a connecting frame 154 extending to the lower end of the through hole. The bottom of the connecting frame 154 is equipped with a motor 201 with a rotating shaft connected to the receiving tray 104. The first moving cylinder 202 has its cylinder body fixedly connected to the workbench 101, and its piston is connected to the connecting frame 154. This allows the receiving tray 104 to move longitudinally and horizontally on the workbench 101. When the receiving column 141 on the receiving tray 104 is full of nuts, the receiving tray 104 is moved to other areas for tool retrieval via the slide rail 105 and the slider 151. For example, when the receiving tray 104 is full of nuts, it is moved to a position outside the discharge head 103 and then retrieved by a power tool. The magnetic suction part in the power tool will directly attract the nuts. Moreover, multiple nut guns with multiple heads can be configured according to the target equipment to retrieve nuts simultaneously, solving the problem of low efficiency in manual nut loading.

[0048] In one embodiment of this application, the vibrating feeder 102 is connected to a receiving device 107 via a conveying pipe, and the receiving device 107 is connected to a discharge head 103. The receiving device 107 ensures a better fit between the conveying pipe and the discharge head 103, preventing mismatches in their connection positions that could lead to problems with the nut locking joint position.

[0049] In one embodiment of this application, as Figure 3 As shown, the discharge head 103 includes: a distributor chute 131, a second cylinder 132, a pusher block 133, and a receiving frame 134; the second cylinder 132 is disposed on one side of the distributor chute 131, and the receiving frame 134 is disposed over the distributor chute 131; the pusher block 133 is disposed in the space between the receiving frame 134 and the distributor chute 131; the distributor chute 131 has a first material hole 135, the pusher block 133 has a second material hole 136, and the receiving frame 134 has a third material hole 137; the third material hole 137 is connected to the conveying pipe 108 through a receiving device; the pusher block 133 is connected to the piston of the second cylinder 132, and the second cylinder 132 drives the pusher block to make the second material hole 136 communicate with the first material hole 135 or with the third material hole 137; the first material hole 135 is the discharge port.

[0050] The screw or nut is fed through the push block 133 provided in the distributor slide 131. Specifically, the distributor slide 131 is provided with a first material hole 135, and the receiving frame 134 is provided with a third material hole 137. The first material hole 135 and the third material hole 137 are offset from each other in the vertical direction. The second cylinder 132 is connected to the push block 133. The push block 133 is pushed by the second cylinder 132, so that the second material hole 136 of the push block 133 can move between the first material hole 135 and the third material hole 137. When the second material hole 136 moves to the first material hole 135 and the third material hole 137, the screw or nut is fed through the push block 133. When the third feed hole 137 is vertically aligned, the material falls from the third feed hole 135 into the second feed hole 136 of the push block 133. The second cylinder 132 pushes the push block 133. When the second feed hole 136 is vertically aligned with the first feed hole 135, the second feed hole 136 and the third feed hole 137 are misaligned, causing the material at the position of the third feed hole 137 to be blocked by the push block 133. Simultaneously, the material in the second feed hole 136 falls into the first feed hole 135. Since the first feed hole 135 is the discharge port, the material then falls from the discharge port into the receiving column 141 of the receiving tray 104. The intermittent rotation of the receiving tray 104 in conjunction with the cylinder enables precise and efficient material feeding.

[0051] In one embodiment of this application, the upper end of the vibrating feeder 101 is further provided with a hopper 106; the lower end of the hopper 106 is an inverted frustum structure; a discharge port 161 is provided on one side of the hopper 106; a pusher plate 163 extending into the interior is provided on the outer side of the bottom end of the hopper 106; a cylinder seat 164 is provided on the outer side of the hopper 106; a third cylinder (not shown in the figure) connected to the pusher plate 163 is provided on the cylinder seat 164.

[0052] Material can be stored in the hopper 106. When the material in the vibrating feed pan 101 is insufficient, the pusher plate 163 can be pushed by the third cylinder to allow the material to fall from the discharge port 161 into the vibrating feed pan, thereby achieving automatic replenishment. When the material in the hopper 106 is insufficient, material can be added from the top, which is convenient for adding material.

[0053] In one embodiment of this application, the hopper 106 is provided with a flow-limiting plate 162 at the discharge port 161; the flow-limiting plate 162 is provided with a vertical limiting groove 165; the hopper 106 is provided with a limiting screw hole for installing a limiting screw at the position corresponding to the limiting groove 165. The flow-limiting plate 162 can block or partially block the discharge port 161 or fully open it, thereby limiting the discharge speed of the hopper 106 and preventing over-discharge or under-discharge; by providing the limiting groove 165 and the corresponding limiting screw on the flow-limiting plate 162, the flow-limiting plate 162 is prevented from falling off the hopper 106; a sensor connection port 166 is also provided at the upper end of the hopper 106 above the discharge port 161 for installing a sensor. This sensor can sense the material in the hopper, for example, a laser sensor, and determine whether there is enough material in the hopper 106 by the reflection of the emitted laser, and remind the staff to add material in time.

[0054] In one embodiment of this application, a linear vibrator 203 is provided at the lower end of the conveying pipe, and a vibrating frame 204 is connected to the lower end of the linear vibrator 203. The linear vibrator 203, also known as a linear feeder or linear vibrating feeder, is a mechanical device that can linearly convey the material conveyed by the vibrating plate. In conjunction with the vibrating plate, it can further ensure that the material can be conveyed to the discharge head 103 position through the conveying pipe.

[0055] In one embodiment of this application, as Figure 6 As shown, it also includes a support frame 301; the support frame 301 is L-shaped; the slide rail 105 and the portion located on and connected to the slide rail 105 are located outside the support frame 301; a slider 151 is slidably disposed on the upper part; wherein, one end of the conveying pipe extends out of the support frame 301 and is connected to the discharge head 103. The support frame 301 provides a supporting framework for the entire device, protecting the device internally and facilitating handling and transportation.

[0056] In one embodiment of this application, as Figure 7As shown, it also includes a protective cover 302, which is disposed outside the support frame 301 to cover the portion of the support frame 301 exposed thereout. The upper end of the support frame 301 is also provided with an alarm connector 303. Through the aforementioned protective cover, the portion disposed outside the support frame 301 is covered. It is opened during operation and closed when not in operation to prevent dust and dirt from falling into the equipment from the factory environment, while also protecting the discharge head 103 and the receiving tray 104. Furthermore, an alarm connector 303 or other indicating unit can be provided at the upper end of the support frame 301 for connecting an alarm, which can be used to provide an alarm when the equipment malfunctions or other problems occur, thus alerting the staff. For example, it can be connected to a sensor to detect whether there is sufficient material in the hopper 106. When the material is insufficient, it can remind the staff to add material, preventing the equipment from running idle due to untimely material replenishment.
