Description

Technical Field

[0001] This utility model relates to the field of automation equipment technology, specifically to a three-axis automatic loading and unloading machine. Background Technology

[0002] Injection molding is a widely used processing technology in modern manufacturing. It is used for mass production of plastic parts with complex structures and high precision requirements. In the traditional injection molding production process, the following steps are usually included: manually placing the metal insert (workpiece) into the injection mold, then closing the mold and performing injection molding, manually removing the injection-molded part after opening the mold, manually cutting off the sprue material of the part, and finally placing the finished product into a material tray for transfer.

[0003] In existing technologies, the entire processing is done manually, resulting in low production efficiency. Furthermore, manual labor is affected by fatigue and it is difficult to match the high-speed cycle of the injection molding machine, thus further reducing production efficiency. Utility Model Content

[0004] To address the technical problems existing in the background art, this utility model proposes a three-axis automatic loading and unloading machine.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: A three-axis automatic loading and unloading machine includes a loading component and a forming component; The feeding assembly includes a feeding machine, on which a feeding conveyor line for conveying material trays, a unloading conveyor line for unloading workpieces, and a transfer structure for transferring workpieces are provided. The transfer structure includes a clamping module and a moving module for driving the clamping module to move in multiple axes. The feeding conveyor line includes a horizontal conveying section fixedly installed on the feeding machine and a rotating section rotating on the feeding machine. The feeding machine is provided with a material tray recycling channel that connects to the rotating section. The molding assembly includes a molding machine and a molding mold mounted on the molding machine. The transfer structure places the workpiece into the molding mold for injection molding and unloads the workpiece after injection molding.

[0006] Preferably, a rotating disk is provided on the molding machine platform, and a number of molding molds are provided on the rotating disk. The molding molds are arranged at equal intervals along the circumference of the rotating disk. Through the above improvements, multiple molding molds are provided on the molding machine platform, realizing the parallel operation of the part picking and molding cooling processes, greatly reducing the idle time of the equipment, which can not only greatly improve production efficiency, but also make the overall layout more compact.

[0007] Preferably, the rotating section includes a rotating bracket hinged to the loading platform, a support bracket mounted on the rotating bracket, and a conveyor belt mounted on the support bracket. A lifting unit is installed inside the loading platform. The actuating end of the lifting unit is connected to the rotating bracket. The lifting unit actuates and forces the rotating bracket to rotate, causing the material tray on the support bracket to slide into the material tray recycling channel. Through these improvements, when an empty material tray needs to be recycled, the rotating section rotates downwards under the drive of the lifting unit to form a ramp, allowing the empty material tray to automatically slide into the recycling channel inside the equipment by gravity, thus achieving automatic recycling of the material tray.

[0008] Preferably, the clamping module includes a mounting plate, a first clamping unit fixedly mounted on the mounting plate, and a second clamping unit slidably mounted on the mounting plate. The first clamping unit is provided with a pulling unit, and the second clamping unit is provided with a connecting plate. The actuating end of the pulling unit is connected to the connecting plate. The pulling unit actuates to bring the first clamping unit and the second clamping unit closer together or further apart. With the above improvements, after the workpiece is injection molded, the distance between the workpieces will change. The distance between the first clamping unit and the second clamping unit can be adjusted by using the pulling unit, thereby clamping the workpiece before injection molding and the workpiece after injection molding.

[0009] Preferably, the mounting plate is provided with limiting elastic elements, and the first clamping unit is slidably disposed between the limiting elastic elements. The limiting elastic elements abut against the first clamping unit and restrict its continued movement. Through the above improvement, the movement stroke of the second clamping unit is restricted by the limiting elastic elements, which makes it easier to adjust the distance between the first clamping unit and the second clamping unit.

[0010] Preferably, the loading machine platform is equipped with a sprue cutting structure, which includes a cutting bracket, a supporting sliding plate slidably disposed on the cutting bracket, a pushing unit for driving the supporting sliding plate to move, and a cutting block disposed on the cutting bracket. The pushing unit drives the supporting plate to move toward the cutting block so that the cutting block cuts off the sprue area of ​​the workpiece. Through the above improvements, the sprue of the injection-molded workpiece is removed, which greatly improves production efficiency and production quality compared to manual removal.

[0011] Preferably, the cutting bracket forms a dropping chute, and the dropping chute is located above the unloading conveyor line. Through the above improvements, the workpiece after the sprue is removed falls from the dropping chute onto the unloading conveyor line, realizing automatic unloading of the workpiece.

[0012] Preferably, the loading machine platform is provided with a transfer seat, which is provided with a first placement slot for placing unmolded workpieces and a second placement slot for placing molded workpieces. Through the above improvements, the workpieces can be placed on the transfer seat, thereby coordinating with the injection cycle of the molding components and making the entire processing process smoother.

[0013] Preferably, a position sensor is provided on the transfer seat, and the position sensor is positioned relative to the workpiece. With the above improvement, the position sensor will only send a signal to the transfer structure when it detects the workpiece, thus avoiding situations such as the transfer structure grabbing empty.

[0014] Preferably, the support bracket is provided with limiting abutment plates on both sides and abutment cylinder for pushing the material tray to press against the limiting abutment plates. The limiting abutment plates form limiting grooves for the material tray to slide. Through the above improvements, not only is the stability of the material tray improved during the feeding process, but also the smoothness and stability of the material tray during the sliding process are improved.

[0015] Compared with the prior art, the present invention has the following advantages and beneficial effects: The material tray is conveyed by the loading conveyor line to the designated position. Then, the transfer structure picks up the workpiece from the tray and places it on the molding die for injection molding. After injection molding is completed, the transfer structure picks up the injection-molded workpiece and unloads it via the unloading conveyor line. After the tray is loaded, it can be rotated by the rotating section to transport the empty tray to the tray recycling channel for unloading. Compared with manual loading and unloading, this method not only greatly improves production efficiency but also significantly reduces the labor intensity of employees. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] It should be understood that although the terms upper, middle, lower, top, one end, etc., appear in this document to describe various elements, these elements are not limited by these terms. These terms are only used to distinguish the elements from each other for ease of understanding, and are not used to define any directional or sequential restrictions.

[0019] like Figure 1-8 As shown, a three-axis automatic loading and unloading machine includes a loading component 1 and a forming component 2; Specifically, the feeding assembly 1 includes a feeding machine 1.1, on which a feeding conveyor line 1.2 for conveying material trays, a discharging conveyor line 1.3 for unloading workpieces, and a transfer structure 1.4 for transferring workpieces. The transfer structure 1.4 includes a clamping module 1.5 and a moving module 1.6 for driving the clamping module 1.5 to move in multiple axes. The feeding conveyor line 1.2 includes a horizontal conveying section 1.7 fixedly installed on the feeding machine 1.1 and a rotating section 1.8 transferred on the feeding machine 1.1. The feeding machine 1.1 is provided with a material tray recycling channel 1.9 that connects to the rotating section 1.8. Furthermore, the molding component 2 includes a molding machine 2.1 and a molding mold 2.2 disposed on the molding machine 2.1. The transfer structure 1.4 places the workpiece into the molding mold 2.2 for injection molding and unloads the workpiece after injection molding.

[0020] Throughout the entire processing, the material tray is conveyed to the designated position via the feeding conveyor line 1.2. Then, the transfer structure 1.4 picks up the workpiece from the material tray and places it onto the molding die 2.2 for injection molding. After injection molding is completed, the transfer structure 1.4 removes the injection-molded workpiece and unloads it via the unloading conveyor line 1.3. After the material tray is loaded, it can be rotated via the rotating section 1.8 to transport the empty material tray to the material tray recycling channel 1.9 for unloading. Compared with manual loading and unloading, this not only significantly improves production efficiency but also greatly reduces the labor intensity of employees.

[0021] like Figure 1 , Figure 2 As shown, as a further explanation of the implementation of the molding component 2 in this embodiment, a rotating disk 2.3 is provided on the molding machine 2.1, and a plurality of molding molds 2.2 are provided on the rotating disk 2.3, with the molding molds 2.2 arranged at equal intervals along the circumference of the rotating disk 2.3.

[0022] By setting multiple sets of molding dies 2.2 on the molding machine 2.1, the parallel operation of part picking and molding cooling processes is realized, which greatly reduces the idle time of the equipment. This not only significantly improves production efficiency, but also makes the overall layout more compact.

[0023] like Figure 1 , Figure 7 , Figure 8 As shown, in a further explanation of the embodiment of the feeding conveyor line 1.2, the rotating section 1.8 includes a rotating bracket 3.1 hinged to the feeding machine platform 1.1, a support bracket 3.2 disposed on the rotating bracket 3.1, and a conveyor belt 3.3 disposed on the support bracket 3.2. A lifting unit 3.4 is provided inside the feeding machine platform 1.1. The actuating end of the lifting unit 3.4 is connected to the rotating bracket 3.1. The lifting unit 3.4 actuates and forces the rotating bracket 3.1 to rotate, so that the material tray on the support bracket 3.2 slides into the material tray recycling channel 1.9.

[0024] When it is necessary to recycle the empty material tray, the rotating section 1.8 rotates downward under the drive of the lifting unit 3.4 to form a ramp, and the empty material tray can automatically slide into the recycling channel inside the equipment by gravity, thus realizing the automatic recycling of the material tray.

[0025] In addition, the support bracket 3.2 is provided with a limiting abutment plate 7.1 on both sides, and an abutment cylinder 7.2 for pushing the material tray to press against the limiting abutment plate 7.1, and a limiting groove 7.3 is formed on the limiting abutment plate 7.1 for the material tray to slide.

[0026] Once the tray moves to the designated position, the abutment cylinder 7.2 will push the tray from the side, causing the tray to abut against the limiting abutment plate 7.1, thereby ensuring the stability of the tray during the feeding process. During the unloading process of the empty tray, the tray can slide along the limiting slide groove 7.3, thereby improving the smoothness and stability of the tray sliding process.

[0027] like Figure 3 , Figure 4 As shown, as a further explanation of the embodiment of the transfer structure 1.4, the loading platform 1.1 is provided with a mounting bracket, the moving module 1.6 includes an X-axis transverse module, a Y-axis transverse module provided on the X-axis transverse module, and a Z-axis transverse module provided on the Y-axis transverse module, and the clamping module 1.5 is provided on the moving end of the Z-axis transverse module.

[0028] Specifically, the clamping module 1.5 includes a mounting plate 4.1, a first clamping unit 4.2 fixedly mounted on the mounting plate 4.1, and a second clamping unit 4.3 slidably mounted on the mounting plate 4.1. The first clamping unit 4.2 is provided with a pulling unit 4.4, and the second clamping unit 4.3 is provided with a connecting plate 4.5. The actuating end of the pulling unit 4.4 is connected to the connecting plate 4.5. When the pulling unit 4.4 is actuated, the first clamping unit 4.2 and the second clamping unit 4.3 are brought closer together or moved further apart.

[0029] After the workpiece is injection molded, the distance between the workpieces will change. The distance between the first clamping unit 4.2 and the second clamping unit 4.3 can be adjusted by the pulling unit 4.4, so as to clamp the workpiece before injection molding and the workpiece after injection molding.

[0030] Furthermore, the mounting plate 4.1 is provided with limiting elastic elements 4.6, and the first clamping unit 4.2 is slidably disposed between the limiting elastic elements 4.6. The limiting elastic elements 4.6 abut against the first clamping unit 4.2 and restrict its continued movement. The limiting elastic elements 4.6 restrict the movement stroke of the second clamping unit 4.3, making it easier to adjust the distance between the first clamping unit 4.2 and the second clamping unit 4.3.

[0031] like Figure 6As shown, in some other embodiments, the loading platform 1.1 is provided with a sprue cutting structure 5.1. The sprue cutting structure 5.1 includes a cutting bracket 5.2, a supporting sliding plate 5.3 slidably disposed on the cutting bracket 5.2, a pushing unit 5.4 for driving the supporting sliding plate 5.3 to move, and a cutting block 5.5 disposed on the cutting bracket 5.2. The pushing unit 5.4 drives the supporting plate to move toward the cutting block 5.5 so that the cutting block 5.5 cuts off the sprue area of ​​the workpiece, thereby removing the sprue from the injection-molded workpiece. Compared with manual cutting, this greatly improves production efficiency and production quality.

[0032] Furthermore, a material drop chute 5.6 is formed on the cutting bracket 5.2, and the material drop chute 5.6 is located above the unloading conveyor line 1.3. After the sprue is removed, the workpiece falls from the material drop chute 5.6 onto the unloading conveyor line 1.3, realizing automatic unloading of the workpiece.

[0033] A pusher structure 8.1 is provided on the cutting bracket 5.2. The pusher structure 8.1 includes a pusher plate 8.2, a pusher rod 8.3 on the pusher plate 8.2, and a pusher unit 8.4 that drives the pusher plate 8.2 to move. The pusher rod 8.3 is positioned opposite to the workpiece. After the sprue is removed, the pusher unit 8.4 can drive the pusher plate 8.2 to move, so that the pusher rod 8.3 pushes the workpiece out of the support plate. The workpiece falls from the drop chute 5.6 onto the unloading conveyor line 1.3, realizing automatic unloading of the workpiece.

[0034] In addition, a sliding rod 9.1 is inserted into the cutting bracket 5.2, and a sliding limit block 9.2 is slidably set on the cutting block 5.5. The sliding rod 9.1 is connected to the sliding limit block 9.2, and an elastic element 9.3 is sleeved on the sliding rod 9.1. One end of the elastic element 9.3 abuts against the cutting platform, and the other end abuts against the sliding rod 9.1, so that the sliding limit block 9.2 always has a tendency to slide towards the workpiece.

[0035] Once the workpiece is in place, the sliding limit block 9.2, under the action of the elastic element 9.3, abuts against the workpiece, completing the limit and achieving flexible clamping of the workpiece. This effectively limits the workpiece and can accommodate the small dimensional tolerances of the workpiece, avoiding rigid impact damage to the workpiece surface.

[0036] Furthermore, the sliding limit block 9.2 has a positioning groove. When the workpiece is cut to remove the sprue, the positioning groove fits against the outer periphery of the workpiece. The positioning groove on the sliding limit block 9.2 can limit the workpiece, thereby further improving the stability of the workpiece during movement.

[0037] In addition, after the sprue is cut, the supporting sliding plate 5.3 will drive the workpiece to reset. After the sliding limit block 9.2 is released from the workpiece, it will automatically reset. During the reset process, since the sprue has been cut off, the sliding limit block 9.2 can push the sprue into the discharge chute 5.6 to realize the discharge of the sprue.

[0038] like Figure 5 As shown, preferably, the loading platform 1.1 is provided with a transfer seat 6.1. The transfer seat 6.1 is provided with a first placement slot 6.2 for placing unmolded workpieces and a second placement slot 6.3 for placing molded workpieces. The workpieces can be placed on the transfer seat 6.1, thereby coordinating with the injection cycle of the molding component 2 and making the whole processing process smoother.

[0039] Furthermore, a position sensor 6.4 is installed on the transfer seat 6.1. The position sensor 6.4 is positioned relative to the workpiece to ensure that the transfer structure 1.4 only operates after the workpiece is placed in the correct position.

[0040] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
