Description

Technical Field

[0001] This invention relates to the field of mechanical equipment, specifically to a material distribution device and an electrical production line. Background Technology

[0002] Switches and sockets typically consist of multiple plastic parts, which need to be sorted, packed, and transported before assembly.

[0003] Taking the housing structure of a switch or socket as an example, the housing structure needs to be packaged in an inner film bag during the production and transportation process. This is followed by subsequent conveying and distribution.

[0004] The existing method mainly involves using a belt conveyor to transport the inner film bags after assembly on the original production line, and employing a combination of cylinders and components for positioning and material distribution. The disadvantages of this method are inaccurate product positioning, inconsistent material feeding directions, high equipment failure rates, and slow production cycles. Furthermore, the cylinders consistently pile up material on the belt conveyor line, and the simultaneous pushing and pushing of the cylinders for material distribution makes the inner film bags highly susceptible to damage. Summary of the Invention

[0005] The purpose of this invention is to overcome at least one defect of the prior art and provide a material dispensing device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A material distribution device includes: a feeding mechanism, a distributing mechanism, a hopper, and a material positioning mechanism. The distributing mechanism is disposed at the discharge end of the feeding mechanism, the hopper is disposed at the discharge end of the distributing mechanism, and the material positioning mechanism is disposed within the hopper.

[0008] The material positioning mechanism includes: multiple material positioning units and a unit driving device that is drively connected to the multiple material positioning units. The multiple material positioning units can move sequentially to the discharge end of the material distribution mechanism under the drive of the unit driving device and receive the output material of the material distribution mechanism.

[0009] Preferably, each material positioning unit includes: a first material positioning plate and a second material positioning plate, wherein the first material positioning plate and the second material positioning plate are arranged in parallel at intervals.

[0010] Preferably, the plurality of material positioning units are arranged at intervals in a direction perpendicular to the discharge direction of the material distribution mechanism.

[0011] Preferably, the unit drive device includes a first transmission mechanism that is driven by the first material positioning plate, a second transmission mechanism that is driven by the second material positioning plate, and a power device.

[0012] Preferably, the first transmission mechanism includes: a first synchronous belt, a first transmission wheel, a first drive wheel, and a first synchronous gear. The first synchronous belt is disposed on the first transmission wheel, the first drive wheel and the first synchronous gear are coaxially linked, the first synchronous gear is driven by the output gear of the power device, and a plurality of first material positioning plates are spaced apart on the first synchronous belt. The second transmission mechanism includes: a second synchronous belt, a second transmission wheel, a second drive wheel, and a second synchronous gear. The second synchronous belt is disposed on the second transmission wheel, the second drive wheel and the second synchronous gear are coaxially linked, the second synchronous gear is driven by the output gear of the power device, and a plurality of second material positioning plates are spaced apart on the second synchronous belt and are synchronized with the position of the first material positioning plates.

[0013] Preferably, the first transmission mechanism further includes a first fixed connecting plate, and the shafts of the first transmission wheel and the first drive wheel are connected to both ends of the first fixed connecting plate;

[0014] The second transmission mechanism further includes a second fixed connecting plate, and the shafts of the second transmission wheel and the second drive wheel are connected to both ends of the second fixed connecting plate;

[0015] The first fixed connecting plate and the second fixed connecting plate are provided with a first transmission wheel and a synchronous belt tensioning adjustment mechanism at one end of the second transmission wheel.

[0016] Preferably, a first baffle is provided in the direction of material discharge of the material distribution mechanism, corresponding to the direction in which the plurality of material positioning units are arranged.

[0017] Preferably, the feeding mechanism includes: a feeding conveyor rail, a material detection sensor, and a first pushing mechanism. The material detection sensor is disposed at the discharge end of the feeding conveyor rail, and the first pushing mechanism is disposed at the discharge end of the feeding conveyor rail, corresponding to the feeding end of the distributing mechanism.

[0018] Preferably, the material distribution mechanism includes: a material distribution rail and a second material pushing mechanism, wherein the material distribution rail is provided corresponding to the discharge end of the material feeding mechanism, and the second material pushing mechanism is provided corresponding to the feed end of the material positioning mechanism.

[0019] The material distribution device of the present invention uses multiple material positioning units to position a single material individually. The multiple material positioning units can move sequentially to the discharge end of the material distribution mechanism under the drive of the unit driving device, and receive the output material of the material distribution mechanism. This enables each material to be discharged individually during subsequent discharge, avoiding the problem of easy wear and tear on the inner film packaging bag caused by the friction between multiple materials under the pushing force of the pushing cylinder or friction with the track during discharge.

[0020] Furthermore, the individual positioning of multiple material positioning units facilitates the gripping and unloading of materials by the robotic arm. In other words, compared to the traditional cylinder-assisted ejection method, the material distribution device further reduces the possibility of wear and tear on the inner film packaging bag.

[0021] Furthermore, multiple material positioning units are arranged with the first material positioning plate and the second material positioning plate spaced apart, and are driven by synchronous belts respectively, so that multiple material positioning units can circulate within the silo. The material inflow and material outflow do not affect each other, which can improve the efficiency of material inflow and outflow, and at the same time reduce the space requirements of the material positioning units in the silo.

Detailed Implementation

[0033] The following embodiments, in conjunction with the accompanying drawings, further illustrate specific implementations of the material dispensing device of the present invention. The material dispensing device of the present invention is not limited to the descriptions in the following embodiments.

[0034] like Figure 1 As shown, the present invention provides a material distribution device, including: a feeding mechanism 100, a distributing mechanism 200, a hopper 300, and a material positioning mechanism 400. The distributing mechanism 200 is disposed at the discharge end of the feeding mechanism 100, the hopper 300 is disposed at the discharge end of the distributing mechanism 200, and the material positioning mechanism 400 is disposed within the hopper 300.

[0035] In this embodiment, the feeding mechanism 100 is mainly responsible for receiving materials from the previous process, such as switch housing components or socket housing components that have just completed inner film packaging. Of course, it can also be some other product components.

[0036] In this embodiment, the material distribution mechanism 200 is used to sequentially distribute the material from the feeding mechanism 100 into the material positioning mechanism 400 in the hopper 300, thereby realizing the individual distribution and positioning of the material so as to facilitate the grabbing or receiving of the material in subsequent processes.

[0037] In this embodiment, as Figure 2 As shown, the material positioning mechanism 400 includes: a plurality of material positioning units 410 and a unit driving device 420 that is drively connected to the plurality of material positioning units 410. The plurality of material positioning units 410 can move sequentially to the discharge end of the material distribution mechanism 200 under the drive of the unit driving device 420 and receive the output material of the material distribution mechanism 200.

[0038] In this embodiment, the material positioning mechanism 400 can be fixed to the silo 300 via the mechanism positioning plate 490. Specifically, the silo 300 has multiple support frames 320 on its frame 310, and the material positioning mechanism 400 is fixed to the support frames 320 via the mechanism positioning plate 490.

[0039] In one specific implementation, each material positioning unit 410 includes a first material positioning plate 411 and a second material positioning plate 412, which are arranged parallel to each other. The use of two material positioning plates, spaced apart, provides space for subsequent gripping by the robotic arm.

[0040] Furthermore, the plurality of material positioning units 410 are arranged at intervals in a direction perpendicular to the discharge direction of the material distribution mechanism 200. This allows each material positioning unit 410 to be transported sequentially in the vertical direction; of course, they can also be arranged sequentially in the horizontal direction.

[0041] In this embodiment, the unit driving device 420 includes a first transmission mechanism 421 connected to the first material positioning plate 411, a second transmission mechanism 422 connected to the second material positioning plate 412, and a power device 423. That is, in this embodiment, the first material positioning plate 411 and the second material positioning plate 412 of each material positioning unit are driven by independent mechanisms, which allows for further optimization of the transmission structure in space. For example, if both material positioning plates are transmitted through the same mechanism in the same direction, the unidirectional transmission space will inevitably be limited. After each material positioning (e.g., 8 materials at a time), a reset and discharge operation is required, causing a stop in material distribution. However, if the two material positioning plates are transmitted independently, cyclic operation can be achieved without stopping material distribution.

[0042] Specifically, to achieve the cyclic operation process, the first transmission mechanism 421 includes: a first synchronous belt 4211, a first transmission wheel 4212, a first drive wheel 4213, and a first synchronous gear 4214. The first synchronous belt 4211 is disposed on the first transmission wheel 4212. The first drive wheel 4213 is coaxially linked with the first synchronous gear 4214. The first synchronous gear 4214 is connected to the output gear 4231 of the power device 423. A plurality of first material positioning plates 411 are spaced apart on the first synchronous belt 4211. The second transmission mechanism 422 includes: a second synchronous belt 4221, a second transmission wheel 4222, a second drive wheel 4223, and a second synchronous gear 4224. The second synchronous belt 4221 is disposed on the second transmission wheel 4222. The second drive wheel 4223 is coaxially linked with the second synchronous gear 4224. The second synchronous gear 4224 is connected to the output gear 4231 of the power device 423. A plurality of second material positioning plates 412 are spaced apart on the second synchronous belt 4221 and are synchronized with the position of the first material positioning plate 411.

[0043] In a further embodiment, a material detection sensor (not shown in the figure) is provided in the hopper 300 at the corresponding feeding position. When the material from the dispensing mechanism 200 is pushed in, the material detection sensor can detect whether the material on the material positioning unit 410 is in place. If it is in place, a signal is sent to the unit driving device 420 to drive the next material positioning unit 410 to move up, and the current material positioning unit 410 moves down one position.

[0044] In this embodiment, the power unit 423 can be an electric motor, preferably a servo motor, to facilitate transmission control. The synchronous belt transmission method can realize the synchronization of the first material positioning plate 411 and the second material positioning plate 412. At the same time, the first transmission mechanism 421 and the second transmission mechanism 422 use the same power unit 423 and are transmitted by meshing with the output gear 4231 through the first synchronous gear 4214 and the second synchronous gear 4224, thereby realizing the synchronous movement of the synchronous belt. This can ensure that the first material positioning plate 411 and the second material positioning plate 412 of the same material positioning unit 410 arrive at the discharge end of the material distribution mechanism 200 at the same time.

[0045] In this embodiment, the first transmission mechanism 421 further includes a first fixed connecting plate 4215, and the shafts of the first transmission wheel 4212 and the first drive wheel 4213 are connected to both ends of the first fixed connecting plate 4214. The second transmission mechanism 422 further includes a second fixed connecting plate 4225, and the shafts of the second transmission wheel 4222 and the second drive wheel 4223 are connected to both ends of the second fixed connecting plate 4225. A synchronous belt tensioning adjustment mechanism 425 is provided at one end of the first fixed connecting plate 4215 and the second fixed connecting plate 4225 where the first transmission wheel 4212 and the second transmission wheel 4222 are located. Of course, the other shaft ends of the first transmission wheel 4212 and the second transmission wheel 4222 are mounted through a mechanism fixing plate 490.

[0046] Specifically, such as Figure 5 As shown, the bottom ends (the setting ends of the first transmission wheel 4212 and the second transmission wheel 4222) of the first fixed connecting plate 4215, the second fixed connecting plate 4225, and the mechanism fixing plate 490 are provided with key-shaped shaft holes 4217, which can adjust the position of the shafts of the first transmission wheel 4212 and the second transmission wheel 4222 on the shaft holes to achieve the tension adjustment of the synchronous belt, thereby ensuring that the positions of the first material positioning plate 411 and the second material positioning plate 412 are synchronized.

[0047] Furthermore, in the direction of material discharge from the material distribution mechanism 200, a first baffle plate 440 is provided corresponding to the direction in which the plurality of material positioning units 410 are arranged. The top of the first baffle plate 440 is provided with an angled edge 441 to guide the material in case the material distribution mechanism 200 fails to push the material into position. Further, such as... Figure 4 As shown, a second baffle plate 460 is also provided in the discharge direction to limit the material entering the material positioning unit 410. The height of the second baffle plate 460 at the feed end is greater than the height of the first baffle plate 440, so as to limit the material in the feeding direction and stop the material. The length of the second baffle plate 460 extending in the opposite direction to the feed end is shorter than the length of the first baffle plate 440, so as to leave room for the material discharge port 487 below, so as to facilitate the discharge of the material in the subsequent process (such as...). Figure 4 (As shown).

[0048] In this embodiment, as Figure 1 and Figure 3As shown, the feeding mechanism 100 includes: a feeding conveyor rail 110, a material detection sensor 120, and a first pushing mechanism 130. The material detection sensor 120 is located at the discharge end of the feeding conveyor rail 110, and the first pushing mechanism 130 is located at the discharge end of the feeding conveyor rail 110, corresponding to the feeding end of the distributing mechanism 200. The feeding conveyor rail 110 uses belt transmission and is driven by a motor. A limiting stop is provided at the discharge end to limit the material. The material detection sensor 120 is also provided at the discharge end to detect whether the material is in place, so as to send a signal to the first pushing mechanism 130 to push the material. The first pushing mechanism 130 can be driven by a cylinder.

[0049] In this embodiment, as Figure 3 As shown, the material distribution mechanism 200 includes a material distribution rail 210 and a second pushing mechanism 230. The material distribution rail 210 is disposed at the discharge end of the feeding mechanism 100, and the second pushing mechanism 230 is disposed at the feed end of the material positioning mechanism 400. The material distribution rail 210 is disposed on one side of the feeding transmission rail 110. The material distribution rail 210 is a non-powered rail and is only used for limiting. The material is pushed by the second pushing mechanism 230, which can also be driven by a cylinder. Similarly, a material detection sensor (not shown in the figure) can be disposed at the material distribution rail 210 for detection.

[0050] The operation process of the material distribution mechanism in this embodiment is as follows:

[0051] S1, after the material (switch housing assembly or socket housing assembly with inner film packaging bag) enters the feeding conveyor rail 110, it moves towards the discharge end under the drive of the motor. When the material reaches the discharge end, the material detection sensor 120 detects that the material is in place and sends a signal to the first pushing mechanism 130. The first pushing mechanism 130 pushes the material into the distributing mechanism 200.

[0052] S2, the material distribution track 210 of the material distribution mechanism 200 detects that the material is in place and sends a signal to the second pushing mechanism 230. The second pushing mechanism pushes the material into the hopper 300 and into the material positioning mechanism 400.

[0053] S3, the material positioning unit 410 is positioned under the drive of the unit driving device 420, that is, the first material positioning plate 411 and the second material positioning plate 412 are positioned under the drive of the first synchronous belt 4211 and the second synchronous belt 4221, and receive the material pushed out by the material distribution mechanism 200.

[0054] S4, when the material detection sensor detects material on the material positioning unit 410, it sends a signal to the material driving device 420. The first synchronous belt 4211 and the second synchronous belt 4221 drive the first material positioning plate 411 and the second material positioning plate 412 to move downward, so that another set of material positioning units can receive materials. Repeat steps S3-S4. After the predetermined number of materials are received, the material picking mechanism of the next process will grab and take away the materials on multiple material positioning units.

[0055] Based on the above embodiments, this application can also provide an electrical appliance production line, which includes the aforementioned material distribution device. This production line can be used to produce electrical appliances such as switches and sockets.
