A plurality of magnet holes are arranged near the edge of the feeding turntable, and magnets are embedded in the magnet holes. The feeding system includes a feeding box, a feeding box support plate, a discharge port channel and a scraper. In this solution, the feeding turntable is driven to rotate by a motor, and the magnets on the feeding turntable absorb the bolts and bring them to the discharge port channel, and the absorbed bolts are scraped off through the discharge port channel for discharging. However, this solution is only applicable to parts that can be absorbed by magnets, but not to plastic parts, and the application scenarios are limited. Utility Model Content

[0004] The purpose of the utility model is to overcome the shortcomings of the prior art and provide a parts quantitative replenishment device, which is suitable for the quantitative replenishment of parts that can be magnetically adsorbed and parts that cannot be magnetically adsorbed, including plastic parts, and has a wide range of application scenarios.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0008] Furthermore, the bottom surface of the material box is an arc surface that matches the outer circumference of the turntable, and the generatrix of the arc surface forms an angle with the horizontal plane, and the turntable is located at the bottom of the arc surface. Through the inclined setting of the arc surface, the parts in the material box are gathered to the bottom, that is, to the end where the turntable is set, ensuring that the turntable rotates to the notch at the bottom of the turntable.

The discharge channel is tilted to ensure that the parts in the discharge channel can slide down along the discharge channel under their own gravity.

[0010] Furthermore, the sensing structure is an infrared grating sensor. The infrared grating sensor includes a transmitting end and a receiving end, and the transmitting end and the receiving end are respectively located on the inner walls of both sides of the discharge channel.

When the counter counts to a preset number, the number of parts entering the receiving box reaches a target number, and when taking parts from the receiving box, the receiving box is pressed down to make the mounting plate swing, thereby changing the distance between the metal block at the bottom of the mounting plate and the metal detection sensor. When the distance is shortened to a certain range, the metal detection sensor detects the metal block, thereby triggering an output signal to the counter to reset the counter, and repeating the quantitative supply of parts.

[0026] Embodiment 1

[0027] A parts quantitative supply device, such as Figures 1 to 3As shown, it includes a frame 1, a control system, a driving mechanism 2, a turntable 3, a material box 4, a discharge channel 5, a material receiving box 6, a counter 7 and a sensing structure 8; the driving mechanism 2, the material box 4, the discharge channel 5, the material receiving box 6 and the counter 7 are respectively installed on the frame 1, and the output end of the driving mechanism 2 is transmission-connected with the turntable 3; the turntable 3 rotates in the material box 4, and is used to carry the parts to the discharge channel 5; the sensing structure 8 is arranged in the discharge channel 5, and is used to detect the parts in the discharge channel 5; the material receiving box 6 is supported at the end of the discharge channel 5; the driving mechanism 2 and the counter 7 are respectively communication-connected with the control system, and the sensing structure 8 is communication-connected with the counter 7; a plurality of notches 301 for storing parts are opened on the outer periphery of the turntable 3, and the notches 301 can be connected with the discharge channel 5 so that the parts in the notches 301 fall into the material receiving box 6 along the discharge channel 5.

[0028] When the above-mentioned parts quantitative replenishment device is used, the number of parts to be taken is first preset in the counter 7, and the control system controls the driving mechanism 2 to operate, and the driving mechanism 2 drives the turntable 3 to rotate. Since the turntable 3 is located in the material box 4 and a notch 301 is provided on the outer periphery of the turntable 3, the parts in the material box 4 enter the notch 301, and when the turntable 3 rotates, the parts in the notch 301 move synchronously. When the turntable 3 rotates to the corresponding notch 301 and docks with the discharge channel 5, the parts in the notch 301 slide down the discharge channel 5 and fall into the receiving box 6. Among them, when the parts pass through the discharge channel 5, the sensing structure 8 in the discharge channel 5 senses the parts and communicates with the counter 7 to count. When the number reaches the preset number of parts to be taken, the counter 7 communicates with the control system to control the driving mechanism 2 to stop running and the turntable 3 to stop working. At this time, the number of parts in the receiving box 6 is the preset number of parts to be taken. This embodiment can select parts in a quantitative manner, and the staff can take away the parts needed for assembly at one time, avoiding ineffective walking and waste of working time caused by repeated back and forth movements, reducing the labor load of the staff, and is suitable for quantitative supply of parts that can be magnetically adsorbed and parts that cannot be magnetically adsorbed, including plastic parts, and has a wide range of application scenarios.

[0029] Specifically, Figure 3As shown, four notches 301 are evenly arranged on the outer circumference of the rotating disk 3, and the notches 301 include arc segments 3011 and straight segments 3012. When the notches 301 are connected to the discharge channel 5, the straight segment 3012 is located below the arc segment 3011, and one end of the straight segment 3012 is connected to the arc segment 3011, and the other end of the straight segment 3012 is connected to the discharge channel 5. When the straight segment 3012 is connected to the discharge channel 5, the plane where the straight segment 3012 is located is 35° with the horizontal plane. When the parts fail to enter the discharge channel 5 from the notches 301, when the rotating disk 3 continues to rotate, the parts slide along the inner wall of the notches 301 to the bottom of the notches 301, so that the parts can continue to be stored in the notches 301 and return to the material box 4 during the operation of the rotating disk 3, ensuring that the parts do not fall on the way back. At the same time, the arrangement of the arc segment 3011 can further block the parts in the notches 301, and further prevent the parts from falling on the way back. It should be noted that the number of the notches 301 on the outer circumference of the turntable 3 can be designed according to actual needs.

[0030] The driving mechanism 2 includes a motor, and the output shaft of the motor is coaxially connected to the turntable 3. It should be noted that the driving mechanism 2 may include other structures that can realize the transmission connection between the motor and the turntable 3.

[0031] like Figure 1 , Figure 2 As shown, the cross section of the discharge channel 5 is "U"-shaped, the bottom surface of the discharge channel 5 forms an angle with the horizontal plane, the top of the discharge channel 5 is connected to the notch 301, and the bottom of the discharge channel 5 is supported by the receiving box 6. In this embodiment, the discharge channel 5 is inclined to ensure that the parts in the discharge channel 5 can slide down along the discharge channel 5 under their own gravity.

[0032] The sensing structure 8 is an infrared grating sensor. The infrared grating sensor includes a transmitting end and a receiving end, and the transmitting end and the receiving end are respectively located on the inner walls of both sides of the discharge channel 5. The transmitting end is used to transmit infrared light, and the receiving end is used to receive infrared light. When the part passes between the transmitting end and the receiving end, the infrared light will be blocked, causing the received infrared signal to change, and the counting function will be realized in cooperation with the counter 7.

[0033] The counter 7 includes an adjustment dial for presetting the number of parts replenishment. When different numbers of parts need to be taken, the required number of parts to be taken can be preset by adjusting the dial; or when different parts need to be taken, if the required number of different parts is different, the number of different parts to be taken can be preset by adjusting the dial respectively.

[0034] like Figure 1As shown, the frame 1 is provided with a start button 9, which is connected to the control system. In this embodiment, after the number of parts to be taken is preset, the start button 9 is pressed, and the control system controls the driving mechanism 2 to operate and start quantitatively replenishing parts. When the number of parts falling into the receiving box 6 reaches the preset number, the counter 7 communicates with the control system and automatically stops the parts replenishment.

[0035] like Figure 1 As shown, the frame 1 is provided with an emergency stop button 10, which is connected to the control system. When the device fails during use, such as when a part is stuck, the staff can press the emergency stop button 10 to stop the device.

[0036] Embodiment 2

[0037] This embodiment is similar to the first embodiment, except that Figure 1 , Figure 2 As shown, the bottom surface of the material box 4 is an arc surface that matches the outer circumference of the turntable 3, and the generatrix of the arc surface forms an angle with the horizontal plane, and the turntable 3 is located at the bottom of the arc surface. In this embodiment, through the inclined setting of the arc surface, the parts in the material box 4 are gathered to the bottom, that is, to the end where the turntable 3 is set, ensuring that the turntable 3 rotates to the notch 301 is located at the lower part of the turntable 3. Parts enter the notch 301, reducing the waste of man-hours caused by waiting for the parts to enter the notch 301 and smoothly enter the material receiving box 6.

[0038] Embodiment 3

[0039] This embodiment is similar to the second embodiment, except that Figure 1 , Figure 2 As shown, it also includes an extension arm 11 and a mounting plate 12, one end of the extension arm 11 is fixed to the frame 1, one end of the mounting plate 12 is connected to the other end of the extension arm 11, and the material receiving box 6 is installed at the other end of the mounting plate 12. In this embodiment, through the extension arm 11 and the mounting plate 12, the material receiving box 6 can be smoothly connected to the end of the discharge channel 5 after installation. At the same time, the mounting plate 12 with the material receiving box 6 installed forms a cantilever structure, and the end of the mounting plate 12 with the material receiving box 6 installed is a free end. When taking parts from the material receiving box 6, pressing the material receiving box 6 downward can make the mounting plate 12 bend downward. When the parts are taken out, the pressure applied to the material receiving box 6 disappears, and the mounting plate 12 is reset.

[0040] It also includes a reset mechanism for resetting the counter 7, and the reset mechanism is in communication with the counter 7. Specifically, Figure 1 , Figure 2As shown, the reset mechanism includes a metal detection sensor 13 and a metal block. The metal detection sensor 13 is installed on the frame 1, and the metal block is installed on the bottom of the mounting plate 12. The metal block corresponds to the position of the metal detection sensor 13, and the metal detection sensor 13 is connected to the counter 7 for communication. During implementation, when the counter 7 counts to a preset number, the number of parts entering the receiving box 6 reaches the target number, and when taking parts from the receiving box 6, the receiving box 6 is pressed down to make the mounting plate 12 swing, thereby changing the distance between the metal block at the bottom of the mounting plate 12 and the metal detection sensor 13. When the distance is shortened to a certain range, the metal detection sensor 13 detects the metal block, thereby triggering an output signal to the counter 7 to reset the counter 7, and repeating the quantitative supply of parts.

In order to make the description concise, not all possible combinations of the above-mentioned technical features are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

For ordinary technicians in the relevant field, other different forms of changes or modifications can be made on the basis of the above description.
