Description

Technical Field

[0001] This invention belongs to the field of wire harness manufacturing technology, specifically relating to a device with automatic loading and unloading of multiple part numbers. Background Technology

[0002] Electronic wire harnesses typically consist of wire harnesses and terminal connectors. They bridge the gap between two or more isolated electronic circuits, enabling current flow and allowing various electronic components to perform their functions. They are an indispensable component in various electrical and electronic devices. Terminal blocks are accessories used to achieve electrical connections. Industrially, they fall under the category of terminal blocks. With increasing industrial automation and more stringent and precise industrial control requirements, the demand for terminal blocks is gradually rising. Due to this surge in demand, terminal block production has evolved from manual to automated processes. Therefore, automated loading and unloading equipment is needed in the terminal block production process. However, existing loading and unloading equipment still has several problems, including:

[0003] 1. In the existing loading and unloading equipment, the terminals are discharged directly from the conveyor belt during unloading, which causes the terminals to be damaged by impact when falling. In addition, the terminals fall in a messy manner, which is not conducive to collecting and packaging the terminals.

[0004] 2. Existing loading and unloading equipment mostly uses a vibratory plate to align the semi-finished products during loading, and then transfers the aligned semi-finished products to the conveyor belt. However, due to the height difference between the vibratory plate and the conveyor belt, the vibratory plate needs to be raised, which is not conducive to the stability of the vibratory plate and also not conducive to adding semi-finished products into the vibratory plate. Summary of the Invention

[0005] To address the issues of terminal blocks being directly discharged from the conveyor belt, resulting in damage upon impact and disorder after falling, which hinders collection and packaging, the present invention aims to provide an automatic loading and unloading device with multiple part numbers to solve these problems.

The feeding section electric push rod is fixedly disposed on the U-shaped base. The lifting plate is slidably disposed within the U-shaped limiting frame. The end of the output shaft of the feeding section electric push rod is fixedly connected to the lifting plate. The vibratory feeder connecting groove plate is fixedly disposed on one side of the U-shaped limiting frame. The lifting plate can be aligned with the vibratory feeder connecting groove plate. The limiting component is disposed on the feeding section electric push rod and is used to restrict the movement of the wiring terminals. The conveying component is disposed on the U-shaped limiting frame and is located above the vibratory feeder connecting groove plate and the lifting plate, and is aligned with the guide groove plate.

[0011] In a preferred embodiment, the limiting assembly includes two fixed inclined plates, four limiting shells, four pins, and four limiting blocks. All four components are located within a U-shaped limiting frame. The two fixed inclined plates are symmetrically and fixedly mounted on the electric push rod of the feeding section. The four limiting shells are respectively fixed and symmetrically mounted on the two fixed inclined plates, and are located on both sides of the lifting plate. Each limiting shell has an inclined groove, and the pins are fixedly mounted within the groove. Each limiting block is rotatably mounted within the groove and rotatably sleeved on the pin.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] This device features automatic loading and unloading of multiple part numbers. The terminal blocks can move from the guide trough plate to the top of the collection shell, allowing the electric push rod of the pressing part to press the terminal blocks down into the collection shell. This enables multiple terminal blocks to be stacked in an orderly manner, facilitating the collection and packaging of the terminal blocks. Furthermore, the spring pieces can support the terminal blocks, allowing them to descend sequentially and contact the spring pieces below during stacking, preventing the terminal blocks from falling from a height and thus avoiding damage to the terminal blocks.

[0018] This device features automatic loading and unloading of multiple material numbers. The vibratory feeder connecting trough can push semi-finished products onto the lifting plate. The electric push rod of the loading section can lift the semi-finished products upward through the lifting plate, so that after multiple semi-finished products are stacked, the topmost semi-finished product can be aligned with the guide trough, which facilitates the movement of the semi-finished products onto the guide trough, avoids raising the vibratory feeder, and makes it easier to add semi-finished products into the vibratory feeder, thus improving convenience.

[0019] This device features automatic loading and unloading of multiple material numbers. When lifting semi-finished products upwards, the semi-finished products can squeeze the limiting blocks, allowing the limiting blocks to move completely into the inclined groove. When the semi-finished products move above the limiting blocks, the limiting blocks can rotate around the pin rod under the influence of gravity, allowing one end of the limiting blocks to rotate out of the inclined groove. This allows the semi-finished products to be placed on multiple limiting blocks, thus facilitating the support of the semi-finished products and making it easier to stack them upwards.

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0031] For examples, please refer to Figure 1-9 The present invention provides a device for automatic loading and unloading of multiple material numbers, including a guide trough plate 1, a loading mechanism 2 and a unloading mechanism 3. The loading mechanism 2 and the unloading mechanism 3 are both connected to the guide trough plate 1, and the loading mechanism 2 and the unloading mechanism 3 are respectively located at both ends of the guide trough plate 1.

[0032] In this embodiment, please refer to Figure 1 or Figure 7-9The feeding mechanism 3 includes a U-shaped frame 31, a pressing electric push rod 32, a pressing block 33, a base frame 34, a discharge plate 35, a discharge assembly 36, a collection shell 37, two fixing blocks 38, and multiple spring pieces 39. The two fixing blocks 38 are fixedly mounted on the end of the guide trough plate 1 away from the feeding mechanism 2, and are symmetrically arranged. The collection shell 37 is fixedly mounted on the two fixing blocks 38, and the inner cavity of the collection shell 37 is aligned with the groove on the guide trough plate 1. The base frame 34 and the discharge plate 35... All are fixedly installed at the end of the collection shell 37 away from the fixing block 38. Multiple grooves 310 are opened inside the collection shell 37. Multiple spring pieces 39 are fixedly installed in the multiple grooves 310 respectively. The U-shaped frame 31 is fixedly installed on the two fixing blocks 38. The lower pressing part electric push rod 32 is fixedly installed on the U-shaped frame 31. The pressing block 33 is fixedly installed at the end of the output shaft of the lower pressing part electric push rod 32. The pressing block 33 is located directly above the inner cavity of the collection shell 37. The discharge assembly 36 is installed on the collection shell 37.

[0033] The vibratory feeder is connected to the feeding mechanism 2, enabling the feeding mechanism 2 to transfer the semi-finished product from the vibratory feeder to the guide trough 1 and push the semi-finished product to move on the guide trough 1. This allows the semi-finished product to pass through the processing station and be processed into a terminal block on the guide trough 1. The semi-finished product then pushes the processed terminal block to move on the guide trough 1, allowing the terminal block to move to the top of the uppermost spring piece 39 inside the collection shell 37. The electric push rod 32 of the lower pressing part pushes the pressing block 33 downwards, causing the pressing block 33 to press down on the terminal block located above the collection shell 37. The terminal blocks press against the spring 39, causing the spring 39 to retract into the groove 310, thereby allowing the terminal blocks to fall between the second layer of spring 39 and the first layer of spring 39. After multiple operations, multiple terminal blocks can be stacked together in an orderly manner. The discharge assembly 36 can push the stacked terminal blocks onto the discharge plate 35, facilitating the orderly collection of the terminal blocks. The base frame 34 can support the collection shell 37, making the collection shell 37 the same height as the feeding mechanism 2, thereby making the guide trough 1 horizontal and improving stability.

[0034] The discharge assembly 36 includes a push plate 3601, a motor 3602, a lead screw 3603, and a threaded sleeve 3604. The collection shell 37 has a strip-shaped hole. The lead screw 3603 is rotatably disposed in the strip-shaped hole, and the threaded sleeve 3604 is slidably disposed in the strip-shaped hole. The threaded sleeve 3604 is threaded onto the lead screw 3603. The push plate 3601 is slidably disposed in the collection shell 37, and the threaded sleeve 3604 is fixedly connected to the push plate 3601. The motor 3602 is fixedly disposed on the collection shell 37, and the end of the output shaft of the motor 3602 is fixedly connected to one end of the lead screw 3603. The motor 3602 can drive the lead screw 3603 to rotate, so that the lead screw 3603 can push the threaded sleeve 3604 to move, which in turn allows the threaded sleeve 3604 to drive the push plate 3601 to move. The push rod can push the stacked terminals onto the discharge plate 35 for easy collection of the terminals.

[0035] The push plate 3601 has multiple process slots 4, which are aligned with multiple spring pieces 39. When the push plate 3601 moves, the spring pieces 39 can pass through the process slots 4 on the push plate 3601, thereby preventing the spring pieces 39 from affecting the movement of the push plate 3601, and enabling the push plate 3601 to completely push out multiple terminals.

[0036] In this embodiment, please refer to Figure 1-6 The feeding mechanism 2 includes a U-shaped base 21, a U-shaped limiting frame 22, a vibrating plate connecting trough 23, a feeding section electric push rod 24, a lifting plate 25, a limiting component 26, and a conveying component 27. The U-shaped limiting frame 22 is fixedly installed at the end of the guide trough 1 away from the fixed block 38, and the end of the U-shaped limiting frame 22 away from the guide trough 1 is connected to the U-shaped base 21. The feeding section electric push rod 24 is fixedly installed on the U-shaped base 21, and the lifting plate 25 is slidably installed inside the U-shaped limiting frame 22. The end of the output shaft of the push rod 24 is fixedly connected to the lifting plate 25. The vibratory feeder connecting groove plate 23 is fixedly installed on one side of the U-shaped limiting frame 22. The lifting plate 25 can be aligned with the vibratory feeder connecting groove plate 23. The limiting component 26 is installed on the electric push rod 24 of the feeding section. The limiting component 26 is used to limit the movement of the wiring terminal. The conveying component 27 is installed on the U-shaped limiting frame 22. The conveying component 27 is located above the vibratory feeder connecting groove plate 23 and the lifting plate 25, and the conveying component 27 is aligned with the guide trough plate 1.

[0037] The vibratory feeder can connect the vibratory feeder connecting trough 23 to the vibratory feeder, allowing the semi-finished product to be pushed onto the vibratory feeder connecting trough 23 and moved onto the lifting plate 25 via the vibratory feeder connecting trough 23. The electric push rod 24 of the feeding part pushes the lifting plate 25 upward, thereby driving the semi-finished product upward, so that the limiting component 26 can fix the semi-finished product on the U-shaped limiting frame 22. At this time, the electric push rod 24 of the feeding part can drive the lifting plate 25 downward, and then lift the new semi-finished product, so that the new semi-finished product can move upward and push the semi-finished product above to move. After multiple operations, multiple semi-finished products can be stacked inside the U-shaped limiting frame 22, so that the semi-finished product above can be aligned with the conveying component 27 and the guide trough 1. The conveying component 27 can push the semi-finished product above onto the conveying component 27, which is convenient for feeding, avoids raising the vibratory feeder, improves stability, and makes it easier to add semi-finished products into the vibratory feeder, thus improving convenience.

[0038] In this embodiment, please refer to Figure 2 , Figure 4 or Figure 6 The limiting assembly 26 includes two fixed inclined plates 2601, four limiting shells 2602, four pins 2603, and four limiting blocks 2604. The two fixed inclined plates 2601, four limiting shells 2602, four pins 2603, and four limiting blocks 2604 are all located within the U-shaped limiting frame 22. The two fixed inclined plates 2601 are symmetrically and fixedly mounted on the electric push rod 24 of the feeding section, and the four limiting shells 2602 are respectively fixed and symmetrically mounted on the two fixed inclined plates. On 2601, four limiting shells 2602 are respectively located on both sides of the lifting plate 25. The limiting shell 2602 is provided with a slanted groove 2605. The pin 2603 is fixedly installed in the slanted groove 2605. The limiting block 2604 is rotatably installed in the slanted groove 2605. The limiting block 2604 is rotatably sleeved on the pin 2603. The end of the limiting block 2604 away from the pin 2603 can pass through the slanted groove 2605. The four limiting blocks 2604 are respectively located on both sides of the lifting plate 25.

[0039] When the semi-finished product moves upward, it can push multiple limit blocks 2604 to rotate, so that the limit blocks 2604 can rotate around the pin 2603 as the axis, and thus the limit blocks 2604 can be completely located inside the inclined groove 2605. When the semi-finished product moves above the limit blocks 2604, due to the inclined setting of the limit blocks 2604, the limit blocks 2604 can rotate and fall under the force of gravity. When one side of the limit blocks 2604 contacts the bottom of the inclined groove 2605, one end of the limit blocks 2604 moves out of the inclined groove 2605, and the semi-finished product can be placed on multiple limit blocks 2604. The lifting plate 25 is small in size and is located between multiple limit blocks 2604, so it will not affect the multiple limit blocks 2604.

[0040] The conveying assembly 27 includes a transmission section electric push rod 2701, a U-shaped connecting frame 2702, and a conveying block 2703. The U-shaped connecting frame 2702 is fixedly installed on the side of the U-shaped limiting frame 22 away from the guide trough plate 1. The transmission section electric push rod 2701 is fixedly installed on the U-shaped connecting frame 2702. The conveying block 2703 is fixedly installed at the end of the output shaft of the transmission section electric push rod 2701. The conveying block 2703 can slide through the interior of the U-shaped limiting frame 22. The conveying block 2703 is aligned with the guide trough plate 1. The electric push rod can push the conveying block 2703 to move, thereby enabling the conveying block 2703 to push the semi-finished product located at the top of the U-shaped limiting frame 22 to move, so that the semi-finished product can slide onto the guide trough plate 1.

[0041] In this embodiment, please refer to Figure 2-4 The end of the U-shaped limiting frame 22 away from the guide trough plate 1 is slidably connected to the U-shaped base 21. The U-shaped limiting frame 22 is provided with multiple adjustment slots 5. Multiple bolts 6 are rotatably provided on the U-shaped base 21. The multiple bolts 6 can be inserted into the multiple adjustment slots 5 respectively, so that the height of the U-shaped limiting frame 22 can be adjusted up and down. The U-shaped limiting frame 22 can be fixed after adjustment by connecting the bolts 6 with the adjustment slots 5. The limiting component 26 is connected to the U-shaped base 21 through the electric push rod 24 of the feeding part, so that the limiting component 26 will not move with the U-shaped limiting frame 22, so that the U-shaped limiting frame 22 can only drive the conveying component 27 to move up and down, which facilitates the adjustment of the height of the conveying component 27, so that the conveying component 27 can be aligned with the guide trough plate 1 of different heights.

[0042] In this embodiment, please refer to Figure 3 or Figure 5An L-shaped plate 7 is fixedly installed at one end of the vibrating plate connecting groove 23 near the U-shaped limiting frame 22. The L-shaped plate 7 is located inside the U-shaped limiting frame 22. A T-shaped rod 8 is slidably inserted into the L-shaped plate 7. An L-shaped blocking block 9 is fixedly installed at one end of the T-shaped rod 8. A spring 10 is installed between the L-shaped blocking block 9 and the L-shaped plate 7. The spring 10 is slidably sleeved on the T-shaped rod 8. The lifting plate 25 can contact the L-shaped blocking block 9. When the lifting plate 25 moves downward, it can press down on the L-shaped blocking block 9. At this time, the upper surface of the lifting plate 25 and the upper surface of the lifting plate 25 are on the same horizontal plane. The L-shaped blocking block 9 can compress the spring 10, so that the L-shaped blocking block 9 can press down on the spring 10. When the blocking block 9 moves downward, the bottom surfaces of the lifting plate 25, the L-shaped blocking block 9, and the upper groove of the vibrating plate connecting groove 23 are on the same horizontal plane, allowing the semi-finished product to move from the vibrating plate connecting groove 23 to the lifting plate 25. After the lifting plate 25 moves upward, the spring 10 can push the L-shaped blocking block 9 upward until the T-shaped rod 8 can no longer move upward. At this time, the height of the upper surface of the L-shaped blocking block 9 is higher than the ground of the upper groove of the vibrating plate connecting groove 23, so that the L-shaped blocking block 9 can block the semi-finished product on the vibrating plate connecting groove 23 and prevent it from falling below the U-shaped limit frame 22, thus improving safety and stability.

[0043] The U-shaped limiting frame 22 is symmetrically equipped with two baffles 11. Both baffles 11 are located on the side of the lifting plate 25 away from the vibrating plate connecting groove 23. When the semi-finished product moves from the vibrating plate connecting groove 23 to the lifting plate 25, it cannot continue to move after contacting the baffle 11, thus preventing the semi-finished product from falling off the lifting plate 25 and improving stability.

[0044] Based on the above, the working principle of this solution is as follows:

[0045] In use, first connect the vibratory feeder connecting trough 23 to the vibratory feeder. Then, the electric push rod 24 of the feeding section moves the lifting plate 25 downwards, aligning the vibratory feeder connecting trough 23, the L-shaped blocking block 9, and the adjusting plate. The vibration of the vibratory feeder pushes the semi-finished product onto the lifting plate 25. When the semi-finished product contacts the stop rod 11, the electric push rod 24 of the feeding section pushes the lifting plate 25 upwards, pushing the semi-finished product upwards so that it can contact the limiting block 2604. The compression and limiting block 2604 can rotate around the pin 2603, allowing the semi-finished product to move above the limiting block 2604. Then, the limiting block 2604 can fall naturally, causing one end to move out of the inclined groove 2605 and the lifting plate 25 to move downward, so that the semi-finished product can be placed on multiple limiting blocks 2604. The electric push rod 24 of the multiple extension and retraction of the feeding part can stack multiple semi-finished products on top of the limiting blocks 2604, so that the semi-finished product on the top can be connected to the conveyor block 27. 03 Alignment: The electric push rod 2701 of the transmission section pushes the conveying block 2703 to move, which can push the uppermost semi-finished product onto the guide trough plate 1. One pushes multiple semi-finished products, so that multiple semi-finished products can move on the guide trough plate 1, and thus multiple semi-finished products can pass through multiple processing stations, and thus be assembled into wiring terminals. The wiring terminals can move to the top of the collection shell 37, so that the wiring terminals are above the spring piece 39. The electric push rod 32 of the pressing section drives the pressing block 33 to move downward, which can press down on the wiring terminals. At this time, the spring piece 39 is forcefully contracted into the groove 310, so that the wiring terminals can move downward. The electric push rod 32 of the pressing section can stack multiple wiring terminals in the collection shell 37 through multiple extensions and retractions. Then, the motor 3602 is started to drive the lead screw 3603 to rotate. The lead screw 3603 can push the lead sleeve 3604 to move, which can drive the push plate 3601 to move, and thus push the multiple stacked wiring terminals onto the discharge plate 35.

[0046] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
