DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Please see attached Figure 1-6 The utility model provides an embodiment: a screw conveying and discharging device, including a material dividing mechanism 1, a material selecting mechanism 3, and a material feeding mechanism 4. The material selecting mechanism 3 is fixedly installed at the top center position of a chassis 5. The material dividing mechanism 1 is arranged on one side of the material selecting mechanism 3, and the material feeding mechanism 4 is located on the top of the material selecting mechanism 3. The material feeding mechanism 4 is provided with a movable tray 402, and the movable tray 402 is directly opposite to the inner cylinder 301 of the material selecting mechanism 3. A material feeding trough 302 is arranged on the outer side of the material selecting mechanism 3, and the material feeding trough 302 is matched with the material feeding mechanism 4. The material dividing mechanism 1 is connected with a conveying mechanism 2.

[0022] The material dividing mechanism 1 is used to guide the screw 6 to the conveying mechanism 2. It plays a role of guiding and diverting, connecting the material selecting mechanism 3 and the conveying mechanism 2 to ensure that the material enters the conveying mechanism 2 from the material selecting mechanism 3 in an orderly manner.

[0023] The material selection mechanism 3 has a vibration and adjustment device to ensure that the screws 6 are arranged in a specified direction. The feeding mechanism 4 includes a movable tray 402, which is used to quantitatively supply screws 6 to the material selection mechanism 3. When it is detected that the number of screws 6 in the material selection mechanism 3 is small, the movable tray 402 increases the inclination angle to inject screws 6 into the material selection mechanism 3 to a limited load, so as to ensure the normal operation of the material selection mechanism 3, and avoid too many screws 6 causing material selection difficulties, or too few screws 6 slowing down production efficiency. The inner cylinder 301 of the material selection mechanism 3 is used to accommodate and rotate the screws 6 for adjustment and arrangement. The screws 6 that meet the requirements enter the material distribution mechanism 1 through the feed trough 302. The feed trough 302 is a channel for conveying materials from the material selection mechanism 3 to the material distribution mechanism 1. The feed trough 302 ensures that the screws 6 are accurately guided into the material distribution mechanism 1, and before being used by the material distribution mechanism 1, it plays the role of caching the screws 6 for further processing. The conveying mechanism 2 is used to convey the screws 6 to the assembly equipment of the production line to ensure a continuous supply of screws 6 and keep the production line running.

[0024] The design of this device ensures that the material selection mechanism 3 has enough spare screws 6, and then the material selection and output automation are realized through the material distribution mechanism 1 and the conveying mechanism 2 to meet the production needs and improve efficiency and accuracy.

[0025] The material dividing mechanism 1 includes a cylinder A101 and a cylinder B108. The material dividing mechanism 1 is fixedly connected to the chassis 5 through a fixed seat 110. The cylinder A101 is fixedly installed on the base 7. A material guide 109 is provided on one side of the base 7. The material guide 109 is connected to the fixed seat 110 through an angle adjustment member 11001. A slide groove 10901 is provided in the material guide 109, and the feed trough 302 and the slide groove 10901 are matched and connected to each other.

[0026] Cylinder A101 is connected to the ejector block 102, a connecting block 107 is embedded in the middle of the telescopic rod of cylinder B108, and the tail thereof penetrates the guide 104. The connecting block 107 is hinged to the limit block 106, and the limit block 106 is rotatably connected to the positioning shaft 105 on the base 7. A feed pipe 112 is provided at one end of the base 7 away from the ejector block 102, and a nozzle 103 is provided just above the feed pipe 112.

[0027] The base 7 is a supporting structure of the material distributing mechanism 1 and is located at the lower part of the material distributing mechanism 1. A material guide 109 is installed on one side of the base 7, and the screw 6 is continuously fed into the chute 10901 under the guidance of the material feeding trough 302.

[0028] Cylinder A101 is connected to the ejection block 102, which is used to push the material selection mechanism 3 into the feed pipe 112 one by one. Cylinder B108 works in conjunction with cylinder A101 to ensure that the screws 6 are transported one by one. A connection block 107 is nested in the middle of the telescopic rod of cylinder B108, which is connected to the limit block 106. The limit block 106 ensures that the screw 6 is pushed into the feed pipe 112 at the appropriate time. After the screw 6 enters the feed pipe 112, the nozzle 103 sprays high-speed compressed gas, so that the screw 6 enters the conveying mechanism 2 through the pipeline and is transported to the assembly equipment of the production line. The various components of the material distribution mechanism 1 work together to ensure that each screw 6 is output in an orderly manner to meet production requirements.

[0029] The conveying mechanism 2 includes a catheter 201, through which the conveying mechanism 2 stores the received screws 6. The middle of the catheter 201 is connected to the adjustment block 202, and a spring 203 is provided between the bottom and the body of the conveying mechanism 2 to ensure that the screws 6 enter the catheter 201 in a controlled manner.

[0030] The feeding mechanism 4 comprises a material storage box 8, a material shortage detector 401, and a movable tray 402. The feeding mechanism 4 ensures that there are enough screws 6 during the processing of the material selection mechanism 3 to avoid the material selection mechanism 3 from running idle. The feeding mechanism 4 comprises a material storage box 8 for storing screws 6. The movable tray 402 is in a trapezoidal shape and is connected to the material storage box. Its wide side is located on one side of the material storage box, and its narrow side is located directly above the material selection mechanism. The material shortage detector 401 is connected to one side of the movable tray through a movable seat. The material shortage detector 401 is located on one side of the movable tray, and a probe 40101 is provided at the bottom. A folding hook is provided at the bottom of the probe 40101 to detect whether there are enough screws 6 in the inner cylinder 301. If the material shortage detector 401 detects that the number of screws in the inner cylinder 301 is insufficient, it can trigger the processing operation of the movable tray 402, and pour the screws 6 into the lower inner cylinder 301 to ensure timely feeding. After reaching the load of the inner cylinder 301, the movable tray 402 immediately resets and stops injecting the screws 6.

[0031] There are three feet 303 at the bottom of the material selection mechanism 3. These feet 303 are evenly distributed at the bottom of the material selection mechanism to balance and stabilize the device. This helps to ensure that the material selection mechanism 3 can accurately process 6 without being affected by imbalance.

Therefore, the embodiments should be regarded as exemplary and non-limiting from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.
