Untimely manual feeding will affect the efficiency of the entire production line; the manual feeding method is inefficient and labor-intensive, and is not suitable for large-scale and high-beat production scenarios, which will cause waste of manpower costs due to frequent movement; the present invention proposes an automatic feeding system for an automatic assembly line, by arranging the main shell on the base, the bolt storage bin is arranged in the main shell, the bolt material is added through the feeding port arranged on the top of the bolt storage bin, the bolt material is lifted to the concave inclined groove by the step feeding lifting subassembly, and then slides one by one to the positioning bracket composed of two parallel support rods, due to the structure of the positioning bracket and the bolt material, the bolt material is vertically and orderly transmitted in the positioning bracket with the screw facing downward, and the vertically transmitted bolt material presents a transmission posture with the screw facing the movement direction after being toggled by the blocking rod, and the bolt material is orderly transmitted one by one on the feeding track to the target position.

[0055] Figure 1 The figure is a schematic structural diagram of an automatic feeding system of an automatic assembly line according to an embodiment of the present invention. Figure 2 Schematic diagram of the structure of the outer surface of the main housing 200 according to an embodiment of the present invention. Specifically, the present application provides an automatic feeding system for an automatic assembly line, the system comprising:

[0056] The base 100 has a main housing 200 disposed thereon.

[0057] The bolt storage bin 201 is arranged in the main housing 200 and fixed on the base 100 through the hopper support frame 202. The bolt storage bin 201 is provided with a feeding port 203 which is set at the top through the main housing 200, and a discharge port is provided on one side of the bolt storage bin 201 to connect to the inclined feeding channel 204. Specifically, the bolt storage bin 201 is arranged in the main housing 200 to provide bolt materials for the automatic feeding system of the automatic assembly line, and the bolt materials are added into the bolt storage box through the feeding port 203; the discharge port of the bolt storage bin 201 is provided with an inclined feeding channel 204, which can make the bolt materials naturally slide to the front end of the discharge port after being added into the bolt storage bin 201, thereby reducing the workload of moving the bolt materials and avoiding the bolt materials being far away from the discharge port in the bolt storage bin 201 and unable to be lifted by the step-up material subassembly 300.

[0058] The bolt positioning assembly includes: a step-loading lifting subassembly 300, a concave inclined groove 400, a positioning bracket 500 and a blocking rod 600.

[0059] The step-loading lifting subassembly 300 is arranged at the discharge port, and the step-loading lifting subassembly 300 is driven to reciprocate in the vertical direction by the cylinder 302 arranged on the step-loading bracket 301, and the step-loading bracket 301 is arranged on the base 100 to lift the bolt material at the front end of the discharge port. Specifically, the step-loading subassembly can effectively utilize the space by vertically lifting the material, and the inclined feeding channel 204 at the discharge port of the bolt storage bin 201 can gather the bolt material to the discharge port to lift it to the concave inclined groove 400; further, the step-loading method can reduce the loss of the bolt material during the loading process, and the step-loading lifting subassembly 300 can intuitively monitor the amount of bolt material in the bolt storage bin 201 and add bolt material to the bolt storage bin 201 in time according to the demand for bolt material.

[0060] The concave inclined groove 400 is used to receive and transfer the bolt material lifted by the step loading and lifting subassembly 300.

[0061] The positioning bracket 500 is composed of two parallel support rods, the spacing between the parallel support rods is less than the diameter of the circumscribed circle of the bolt material head and greater than the screw diameter of the bolt material; the positioning bracket 500 receives the bolt material conveyed by the concave inclined groove and ensures that the screw of the bolt material faces downward. Specifically, the concave inclined groove 400 is an inclined groove, and the shape characteristics and groove width characteristics of the concave inclined groove 400 make the lifted bolt material slide down one by one to the positioning bracket 500 in a posture consistent with the groove direction of the concave inclined groove 400; the positioning bracket 500 is composed of two parallel support rods, which are hollowed out in the middle. The bolt material is composed of a head and a screw, and the size of the head is larger than the screw. The spacing between the two parallel support rods of the positioning bracket 500 is less than the diameter of the circumscribed circle of the bolt material head and greater than the screw diameter. When the bolt material slides down, the screw passes through the positioning bracket 500 and faces downward, and the head is placed above the positioning bracket 500.

[0062] The blocking rod 600 is arranged at the discharge end of the positioning bracket 500, and is used to move the head of the bolt material to lag behind the screw position, so as to ensure that the screw of the material bolt is facing the front end of the movement direction on the next level track. Specifically, the blocking rod 600 is at the discharge end of the tail of the positioning bracket 500 and the feed end of the head of the transmission track 9. When the bolt material is vertically transmitted to the blocking rod 600 on the positioning bracket 500, the blocking rod 600 moves the head of the bolt material so that it is transported on the transmission track in a posture parallel to the next level transmission track.

[0063] The feeding track 700 is arranged at the exit end of the bolt positioning assembly, and receives the bolt materials that have been positioned and transports them to the target position. Specifically, after passing through the bolt positioning assembly, the bolt materials on the feeding track 700 are transported one by one in an orderly manner on the feeding track 700 in a posture that meets the transmission requirements. After the bolt materials are transported to the target position, they are grabbed by the assembly robot arm and assembled according to the set program requirements.

[0064] A power supply component to provide electrical energy.

[0065] In some embodiments, the system further comprises:

[0066] The vibration motor 800 is disposed at the bottom of the feeding track 700 to drive the feeding track 700 and the positioning bracket 500 in the bolt positioning assembly connected to the feeding track 700 to transfer the bolt material to the target position.

[0067] Specifically, the bolt materials passing through the crossbar are transported one by one in an orderly manner on the feeding track 700 in a posture parallel to the feeding track 700 until they are transported to the target position and assembled by the assembly robot arm; the bolt materials on the feeding track 700 meet the posture requirements of the assembly robot arm during assembly.

[0068] Furthermore, the bolt material is transmitted from the positioning bracket 500 to the feeding track 700, and the vibration motor 800 generates vibration and transmits it to the feeding track 700 and the positioning bracket 500. Under the influence of the vibration, the bolt material overcomes the friction between the bolt material and the positioning bracket 500, and between the bolt material and the feeding track 700, so that the bolt material moves in the direction of the vibration motor 800; the vibration frequency of the vibration motor 800 is adjustable to achieve different bolt material transmission efficiencies.

[0069] In some embodiments, the system further comprises:

[0070] The touch screen visualization interface 205 is arranged on the outer surface of the main housing 200 to set the feeding frequency of the cylinder 302, the vibration frequency of the vibration motor 800 and the required quantity range of the bolt material, and respectively control the opening and closing of each component in the automatic feeding system.

[0071] Specifically, the touch screen visualization interface 205 is the control center of the automatic feeding system of the automatic assembly line. Based on the logic control system of the single chip microcomputer, the feeding frequency of the cylinder 302 is controlled to control the frequency of the step feeding sub-assembly for step feeding, the vibration frequency of the vibration motor 800 is controlled to adjust the transmission speed of the bolt material on the positioning bracket 500 and the feeding track 700, and the required quantity range of the bolt material is controlled to control the quantity of the bolt material to meet the production requirements; the touch screen visualization interface 205 can control the opening and closing of each component in the automatic feeding system, and the switch knob 206 set on the outer surface of the main housing 200 controls the opening and closing of the entire automatic feeding system. In some embodiments, the system also includes:

[0072] The switch knob 206 is disposed on the outer surface of the main housing 200 to control the opening and closing of the automatic feeding system of the automatic assembly line.

[0073] Furthermore, in some embodiments, the touch screen visualization interface 205 further includes:

[0074] The log storage module is set in the touch screen visual interface 205 to store the feeding frequency of the cylinder 302, the vibration frequency of the vibration motor 800, the required number range of the bolt material, the counting signal of the bolt material detected by the counting sensor 900, and the abnormal situation as a log. Specifically, the touch screen visual interface 205 is set with a log storage module to record key parameters and events in the automatic feeding process, analyze and take corresponding measures for abnormal situations, analyze improvement points for the data recorded in the log, and improve the feeding performance of the automatic feeding system.

[0075] In some embodiments, the system further comprises:

[0076] The counter module is provided on the touch screen visualization interface 205 and is used to count the number of bolt materials transmitted on the feeding track 700 .

[0077] The counting sensor 900 is arranged on one side of the feeding track 700 to collect counting signals of the bolt materials and transmit them to the counter module for counting.

[0078] In some embodiments, the counting sensor 900 is provided with a light source transmitter and a receiver to emit a light beam to the bolt material and receive reflected light of the bolt material to obtain a counting signal of the bolt material.

[0079] Specifically, when the bolt material is transmitted on the feeding track 700, it passes through the counting sensor 900 arranged on one side of the feeding track 700. The light source transmitter of the technical sensor emits a light beam to the feeding track 700. When the bolt material passes on the feeding track 700, the bolt material will reflect the light signal to the receiver. The counting signal obtained after processing the reflected light signal is transmitted to the counter module to obtain the number of bolt materials passing through the feeding track 700. When the counter module detects that the number of bolt materials is abnormal, the operation of the automatic feeding system is stopped; further, when the number of bolt materials is monitored to be abnormal, the column light alarm 207 and the buzzer alarm 208 located on the upper surface of the main shell 200 issue a warning reminder to remind on-site personnel that the feeding condition of the automatic feeding system is abnormal.

[0080] In some embodiments, the system further comprises:

[0081] The column light warning device 207 is arranged on the upper surface of the main shell 200, so that when the counting signal collected by the counting sensor 900 is transmitted to the counter module for counting and the bolt material is displayed to be higher or lower than the set required number range of the bolt material, the column light warning device 207 emits a red warning light.

[0082] In some embodiments, the system further comprises:

[0083] The buzzer alarm 208 is arranged on the upper surface of the main shell 200, so that when the counting signal collected by the counting sensor 900 is transmitted to the counter module for counting and the number of bolt materials is displayed to be higher or lower than the set required number range of bolt materials, the buzzer alarm 208 emits a buzzer prompt sound.

[0084] In some embodiments, the system further comprises:

[0085] The spare feeding track is arranged at the rear end of the feeding track 700 to receive the remaining required bolt materials and transmit them to the target location through the spare feeding track when the feeding track 700 fails to work normally. Specifically, when the feeding track 700 fails, the staff activates the spare feeding track, which is connected to the feeding track 700 of the automatic feeding system and is responsible for the subsequent transmission of the bolt materials. The bolt materials are placed on the spare feeding track in the required posture and transmitted to the target location.

[0086] The present invention is described below in conjunction with a specific embodiment:

[0087] The present invention feeds the bolts into the bolt storage bin inside the main shell, and the step loading and lifting subassembly lifts the bolt materials at the feeding channel connected to the discharge port of the bolt storage bin into the concave inclined groove, and adjusts the posture by natural sliding in the concave inclined groove, and enters the positioning bracket composed of two parallel bracket support rods and the feeding track with a certain slope. By adding a vibration motor at the bottom of the feeding track, the bolt materials are transmitted in the feeding track and reach the target position. A spare feeding track is set at the tail of the slide rail to achieve seamless docking between the feeding track and the spare feeding track, ensure that the bolt materials reach the target position, and realize the automatic feeding function.
