Description

Technical Field

[0001] The utility model relates to the technical field of material conveying, and more specifically, to a novel circulating flow line feeding device. Background Art

[0002] The assembly line, also known as the assembly line, refers to each production unit focusing on processing only a certain segment of the work to improve work efficiency and output. According to the conveying method, it can be roughly divided into: belt assembly line, plate chain line, double-speed chain, plug-in line, mesh belt line, suspension line and roller assembly line. The assembly line generally includes traction parts, load-bearing components, drive devices, tensioning devices, redirecting devices and supporting parts for supporting traction parts and load-bearing components. It can be used to convey quick connectors, fans, lights, sockets, process boards, storage tables, 24V power supplies, air screws, faucet components and other components. The assembly line combines the conveying system, accompanying carriers and online special machines and testing equipment to meet the conveying requirements of multiple varieties of workpieces.

[0003] In the traditional assembly line, a driving device drives the conveyor line to transfer the carrier with the product from the input end to the output end. After the product is taken out manually or mechanically, the carrier is taken out manually and placed back at the input end of the assembly line. The carrier needs to be transported manually and cannot complete the automatic cycle. At the same time, the manual operation method is not only slow but also requires multiple workers, resulting in low efficiency and high cost. In the existing technology, a lifting assembly line that moves up and down is set at both ends of the upper / lower assembly line with an upper and lower interval to connect the upper / lower assembly line and transport the carrier, so as to realize the automatic circulation of the carrier, and a photoelectric sensor and a control module electrically connected to the driver of the lifting assembly line are set on the upper / lower assembly line and the lifting assembly line. The photoelectric sensor senses the moment when the carrier blocks or does not block the light and generates an electrical signal, which is transmitted to the control module to start the lifting assembly line, so as to realize the automatic lifting of the lifting assembly line. However, there is a certain distance between the lifting assembly line and the assembly line, which will cause the small carrier to be stuck in the distance, affecting the circulation efficiency.

[0004] Therefore, how to design a new circulating assembly line feeding device to solve the above-mentioned technical defects is worthy of careful consideration. Utility Model Content

[0039] A pair of lifting and conveying mechanisms 5, the pair of lifting and conveying mechanisms 5 are correspondingly arranged at both ends of the support frame 1, and each lifting and conveying mechanism 5 includes:

[0040] A lifting frame 51 is provided with a lifting platform 53 on it for sliding in the vertical direction; specifically, the lifting frame 51 and the lifting platform 53 can be made of stainless steel or carbon steel, and the two lifting frames 51 are respectively placed at the downstream end and the upstream end of the conveyor line, and the lifting platform 53 can be slid in the vertical direction by a linear motor, a hydraulic lifting rod, a screw, etc.;

[0042] A toggle arm 6, which is arranged on the top surface of the lifting platform 53, the upper end of the toggle arm 6 slides in the vertical direction, and is provided with a toggle end that slides in the direction parallel to the conveying direction of the conveying group 2; specifically, the toggle arm 6 can be composed of a second linear drive 61, a third linear drive 62, and a toggle block 63, the lower end of the toggle arm 6 can be fixed on the top surface of the lifting platform 53 by welding or screwing, and is located at an end away from the conveying group 2, the upper end of the toggle arm 6 can be realized by the second linear drive 61 to slide in the vertical direction, and the toggle end can be realized by the third linear drive 62 to slide in the direction parallel to the conveying direction of the conveying group 2;

[0043] When the lifting platform 53 rises to a preset distance, the top of the lifting platform 53 contacts the top of the connector 4 .

[0044] In the above technical scheme, when the two ends of the longer conveying group 2 are in different working conditions, such as the upstream end of the conveying group 2 is to put some parts into the carrier 3, a plurality of workstations are set in the conveying process to assemble and form products, and convey them to the downstream end of the conveying group 2. After the product is taken out by the robot at the downstream end, in order to save manpower and conveniently transport the empty carrier 3 to the upstream end, another conveying group 2 is set above or below the conveying group 2 in the opposite direction of its conveying direction, and a lifting conveying mechanism 5 for putting the carrier 3 into or taking out the conveying group 2 and lifting and transporting is added at the head and tail ends of the conveying group 2, so as to realize the empty carrier 3. The beneficial effect of automatically circulating back to the upstream end of the conveying group 2 is that, specifically, when the conveying group 2 on the upper layer conveys the carrier 3 carrying parts and forming products during the conveying process to the rightmost end from left to right, at this time, the manipulator at the right end takes out the product in the carrier 3, and the carrier 3 is conveyed to the connector 4 under the action of the inertia generated by the conveying group 2 to the right.

When the lifting platform 53 rises to contact the side wall of the connector 4 on the upper layer, the toggle end pushes the carrier 3 to the conveying group 2 on the upper layer, thereby realizing effective automatic circulation of the carrier 3. In addition, due to the existence of the connector 4, the distance between the conveying group 2 and the lifting platform 53 can be effectively reduced, and the small carrier 3 can be effectively reduced from being stuck in the distance. In addition, due to the setting of the toggle end, even if the carrier 3 is stuck in the distance, the toggle end can move the carrier 3 from the conveying group 2 to the lifting platform 53.

[0045] In another technical solution, the conveying group 2 on each layer includes a plurality of assembly lines 21 which are arranged end to end and have the same conveying direction, and a carrier 3 is provided on the assembly line 21; specifically, the arrangement of the plurality of assembly lines 21 facilitates the formation of a plurality of workbenches, which facilitates workers or machines to assemble parts into products in multiple steps, and the carrier 3 is used to clamp or carry products for easy transportation.

[0046] In another technical solution, the assembly line 21 is a belt conveyor line; specifically, the belt conveyor line has the advantages of large conveying capacity, simple structure, convenient maintenance, and standardized components, and can effectively convey the carrier 3.

[0047] In another technical solution, the toggle arm 6 includes:

[0048] The second linear driver 61, whose fixed end is arranged on the top surface of the lifting platform 53 and is located on the side away from the assembly line 21, and the movable end of the second linear driver 61 is arranged upward; specifically, the second linear driver 61 can be a linear motor, an electric push rod or a hydraulic rod, and the fixed end of the second linear driver 61 can be fixed on the top surface of the lifting platform 53 by welding or screwing, and the second linear driver 61 provides an upward driving force for the third linear driver 62 described below;

[0049] The third linear drive 62, whose fixed end is arranged on the moving end of the second linear drive 61, and the moving end of the second linear drive 61 is horizontally oriented toward the assembly line 21; specifically, the third linear drive 62 can be a linear motor, an electric push rod or a hydraulic rod, and the fixed end of the third linear drive 62 can be fixed on the moving end of the second linear drive 61 by welding or screwing, and the third linear drive 62 provides a driving force for the horizontal movement of the shift block 63 described below;

The top surface of the connector 4 is tilted and does not contact the transmission belt of the assembly line 21, so that the carrier 3 continues to move forward under the inertia of the transmission belt of the assembly line 21 and is conveniently moved to the connector 4.

[0053] In another technical solution, the support frame 1 and the connector 4 are both provided with a first screw hole;

[0054] It also includes a connecting support plate 7, on which a pair of second screw holes corresponding to the two first screw holes are opened, and the corresponding first screw holes and second screw holes are fixed by bolts and nuts; specifically, the material of the connecting support can be stainless steel or carbon steel to have hardness and rigidity, and is used to support the connecting body 4.

When the carrier 3 moves from the assembly line 21 to the connector 4, the first photoelectric sensor senses that the carrier 3 blocks the light for a moment and generates an electrical signal to transmit to the first control module. The first control module receives the signal and controls the first linear drive 52 to start. The first linear drive 52 drives the lifting platform 53 to rise and fall until it docks with the connector 4. The first photoelectric sensor and the first control module help to achieve the beneficial effects of no manual operation required, high degree of automation and strong adaptability.

[0056] In another technical solution, a second photoelectric sensor and a second control module electrically connected thereto are provided on the lifting platform 53, and the second control module is electrically connected to the first linear drive 52; specifically, when the carrier 3 moves from the connecting body 4 to the lifting platform 53 under the control of the second linear drive 61, the third linear drive 62 and the shift block 63, the second photoelectric signal senses the light blocked by the carrier for a moment and generates an electrical signal to be transmitted to the second control module, the second control module receives the signal and controls the first linear drive 52 to start, the first linear drive 52 drives the lifting platform 53 to rise and fall until it docks with the connecting body 4 on another layer, the second photoelectric sensor and the second control module help to achieve the beneficial effects of no manual operation required, high degree of automation and strong adaptability.
