Description

Technical Field

[0001] This invention relates to the field of mechanical equipment, and in particular to an assembly equipment for multiple materials. Background Technology

[0002] In the field of automated assembly, assembling products containing multiple different types of materials typically requires multiple processes, including sequential material loading, assembly, and quality inspection. Existing multi-material assembly equipment generally suffers from the following shortcomings in practical applications: First, the existing equipment has a loose layout between the assembly and testing units, and the process flow path is complex. Products often need to be transferred ineffectively or in a disorderly manner between multiple units, resulting in low overall production efficiency, large equipment footprint, and inconvenient docking between units.

[0003] Secondly, in existing equipment, quality inspection is often conducted after all assembly processes are completed, or only at a single stage. This centralized or single-stage inspection method cannot effectively identify and remove defective products during assembly, causing them to continue flowing into subsequent processes, resulting in waste of materials and time, and increasing production costs.

[0004] Furthermore, for products that require sequential assembly of various materials with significantly different shapes (such as open boxes, blocks, spheres, and lids), existing equipment lacks flexible material feeding and precise assembly mechanism designs tailored to the characteristics of different materials, making it difficult to efficiently accommodate the material feeding and assembly needs of multiple materials on the same production line.

[0005] In addition, the material transfer and positioning accuracy of each assembly station in existing equipment often depends on the positioning capability of the transmission mechanism itself. When the transmission mechanism (such as a conveyor belt) cannot meet the high-precision positioning requirements, it is easy to cause problems such as assembly misalignment and inaccurate detection, which will affect the product assembly quality and yield.

[0006] In summary, the technical problem that needs to be solved by those skilled in the art is how to design an assembly equipment with a reasonable structure, convenient connection between each unit, the ability to feed multiple materials sequentially and assemble them in order, and to perform multi-station inspection and multiple rejection screenings during the assembly process.

[0010] A further preferred embodiment: the conveyor belt is fixed on the turntable, and the turntable is driven to rotate by a motor or cylinder.

[0011] A further preferred embodiment is that the turntable rotates 90 degrees in a single rotation.

[0012] A further preferred embodiment: the first feeding unit further includes a height detection and transfer mechanism, which includes a detection frame and a detection claw. The detection frame is provided with a transverse slide rail and a longitudinal slide rail. The detection claw is connected to the detection frame to grab the workpiece to be detected from the conveyor belt and transfer it to the first detection position.

[0013] A further preferred embodiment: the rotary positioning mechanism includes a positioning baffle, which is driven to rotate to achieve interception and positioning; The rotary feeding mechanism includes a feeding hopper, a rotating plate, and a staggered push plate, wherein: The bottom end of the hopper is provided with a hopper outlet; The rotating plate is rotatably installed inside the hopper and positioned near the hopper outlet, and the rotating plate has multiple material passages. The misaligned push plate has a feeding port and is driven by a misaligned cylinder to slide back and forth along the discharge direction; The rotating plate is driven to rotate, so that any of the material outlets is connected to the outlet of the hopper; the misalignment cylinder drives the misalignment push plate to move so that the material outlet is connected to the outlet of the hopper to form a material discharge channel.

[0017] By adopting the above technical solution, the present invention has the following advantages compared with the prior art: 1. This invention integrates the first feeding unit, the second feeding unit, the quality control unit, and the output unit sequentially onto the same operating table, forming a complete assembly line module. The units are smoothly connected via conveyor belts and transport rails, ensuring a clear and orderly transfer path for products between processes. This effectively avoids the problems of ineffective or disorderly product transfer between multiple units in existing technologies, significantly improving production efficiency. Furthermore, the equipment has a compact structure and a reasonable layout. 2. This invention sets up multiple inspection points along the assembly process, employing various methods such as thickness inspection, visual inspection, and weight inspection to conduct step-by-step quality monitoring of the product at different assembly stages. Combined with the waste ejection mechanism and waste discharge pipe in the quality control unit, defective products can be immediately rejected online upon detection at any inspection point, preventing them from continuing to flow into subsequent processes and consuming materials and time, thereby effectively reducing production costs and improving the overall product yield. 3. This invention designs dedicated feeding and assembly mechanisms for materials of different shapes and sizes, such as Material 1 (top-open box), Material 2 (block), Material 3 (spherical), and Material 4 (capped). These mechanisms include various forms such as vibratory feeding combined with a pusher plate, suction cup adsorption and transfer, rotary plate quantitative dispensing, and staggered pusher plate dropping. Multiple mechanisms work collaboratively on the same production line, enabling sequential feeding and assembly of multiple materials with significant shape differences. The equipment is highly adaptable and has a wide range of applications. 4. This invention incorporates independent precision transfer and positioning mechanisms at multiple key workstations, such as height detection transfer mechanisms, rotary positioning mechanisms, and weight detection transfer mechanisms. These mechanisms enable secondary precision positioning or transfer of products that have been coarsely positioned on the conveyor belt, overcoming the problem of insufficient positioning accuracy of the conveyor belt itself. This ensures that assembly, inspection, and other operations are completed in precise positions, effectively improving the consistency and reliability of assembly quality. 5. The output unit of this invention adopts a three-axis linkage three-dimensional gripping mechanism, combined with a nine-grid material bin with switch detection function and a waste conveyor belt, which can automatically identify whether the finished product is qualified and place qualified finished products into specific material slots in the nine-grid material bin, while transferring unqualified finished products to the waste conveyor belt. This design realizes intelligent automatic sorting and warehousing management of finished products, further improving the automation level of the equipment. Attached Figure Description

[0020] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0021] It should be noted that in this invention, the terms "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. are all based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this invention and simplifying the description, and are not intended to indicate or imply that the device or element of this invention must have a specific orientation, and therefore should not be construed as a limitation of this invention.

[0022] Example like Figure 1 As shown, this invention discloses an assembly equipment for multiple materials. This equipment is designed for sequential feeding and assembly of multiple materials, multi-station inspection, and multiple rejection screening. It has a reasonable structural design, convenient docking of each unit, and avoids the existing problems of ineffective or disorderly transfer of products between multiple units.

[0023] like Figure 1 As shown, the multi-material assembly equipment includes an operating table and assembly line-style modules mounted on the operating table. The operating table is assembled from multiple operating boxes, each operating box being a box body with supporting legs. The top surface of the box body serves as the mounting surface for the assembly modules, used to fix the assembly modules. Each operating box has an operating table surface, which is inclined, and an operating computer is mounted on the operating table surface. The operating table is also equipped with a work warning light and an alarm notification device, which includes an indicator light and an alarm sound player. In this embodiment, the operating table is assembled from three operating boxes, including two single-opening boxes and one double-opening box. The two single-opening boxes are attached together and then assembled with the double-opening box. Each single-opening box has only one door, and the double-opening box has two doors that can open opposite each other.

[0024] like Figure 1 As shown, the assembly module includes a first feeding unit, a second feeding unit, a quality control unit, and an output unit arranged sequentially. The first feeding unit and the second feeding unit are respectively installed on the two single-opening boxes, while the quality control unit and the output unit are both installed on the double-opening box.

[0025] like Figure 2 and Figure 3As shown, the first feeding unit is the starting unit of the assembly equipment, and the output unit is the terminal unit of the assembly equipment. The first feeding unit includes a first conveying mechanism, which consists of a turntable and a conveyor belt. The turntable is mounted on a single-opening box via a turntable frame. The turntable is driven to rotate by a motor, and the rotation angle of the turntable can be set by configuring the motor. In this embodiment, the turntable rotates reciprocally by the motor, with each rotation angle being 90 degrees. This rotational action is used to switch between two feeding mechanisms, thereby realizing the supply and assembly of two types of materials. Furthermore, the first conveying mechanism is an independent conveyor belt equipped with a conveyor belt.

[0026] Specifically: such as Figure 1 and Figure 2 The two different material supply mechanisms are a first feeding mechanism and a second feeding mechanism. The first feeding mechanism supplies material one to the equipment, and the second feeding mechanism supplies material two to the equipment. The feeding sequence of the first feeding unit is as follows: the first feeding mechanism feeds material one to the first conveying mechanism, and then the turntable rotates to receive material two supplied by the second feeding mechanism. The assembly of material one and material two is completed on the first conveying mechanism. The first feeding mechanism and the second feeding mechanism are respectively located on two perpendicularly intersecting diameters of the turntable.

[0027] like Figure 1 As shown, the first feeding mechanism includes a first feeding bracket, a first feeding conductor, and a first feeding pusher plate. The first feeding bracket is fixed to the single-opening box, and the first feeding conductor is fixed to the first feeding bracket. The height of the first feeding bracket is higher than the turntable frame, so that the material output port of the first feeding conductor is adapted to the conveyor belt, allowing material one to be output onto the conveyor belt. The first feeding conductor has a vertical feeding channel. The material inlet of this feeding channel is the top surface of the first feeding conductor, i.e., the surface facing away from the top of the single-opening box. The material outlet of this feeding channel is arranged towards the transmission mechanism. The material outlet is located adjacent to the first feeding bracket. That is, material one (top-opening box) enters the feeding channel through the material inlet and is transported to the material outlet. Then, it is pushed from the material outlet to the end of the conveyor belt by the first feeding pusher plate, thereby realizing the feeding of material one. The first feeding pusher plate is a driving component driven by a cylinder to push material one out.

[0028] like Figure 1 and Figure 2 As shown, the second feeding mechanism includes a second feeding group, a second feeding conductor, a second feeding bracket, a second feeding push plate, and a second feeding suction cup (see...). Figure 3(As shown). The second feeding bracket is fixed to the single-opening housing, and the second feeding conductor is fixed to the second feeding bracket. The second feeding bracket is set higher than the turntable frame. The second feeding conductor has the same structure as the first feeding conductor, but its size must be adapted to material two. The material outlet of the second feeding conductor is connected to the second feeding bin. Material two (block) enters the feeding channel through the material inlet and is transferred to the material outlet. It is then pushed into the second feeding bin by the second feeding pusher. In this embodiment, the second feeding mechanism includes two second feeding groups, which share one second feeding bin. The material outlets of the second feeding bodies in the two feeding groups are arranged opposite to each other and can both guide material two into the second feeding bin.

[0029] like Figure 2 and Figure 3 As shown, the second feeding bin is an open-top material bin. To match the open-top material bin, the material output by the second feeding mechanism is fed onto the conveyor belt via the second feeding suction cup. The second feeding suction cup is an adsorption-type robotic arm, which uses adsorption of material to achieve the purpose of material transfer.

[0030] like Figure 1 As shown, in the first conveying mechanism, one end of the conveyor belt is the feeding end, and the other end is the discharging end. The discharging end is connected to the feeding end of the second feeding unit. A first detection position is provided near the discharging end. The first detection position uses thickness detection to detect whether material two is loaded into material one. The device for implementing the thickness detection method is a height sensor. This height sensor is used to detect whether the material assembly group (i.e., the assembly of material one and material two) at the first detection position reaches the preset threshold of a qualified product, thereby determining whether the material assembly group is qualified.

[0031] like Figure 1 As shown, a height detection and transfer mechanism is also provided to assist in the detection purpose of the first detection position. Because the conveyor belt in the aforementioned first conveying mechanism cannot be precisely positioned, i.e., it cannot accurately stop at the first detection position, a height detection and transfer mechanism capable of precise positioning is thus provided. Specifically, the height detection and transfer mechanism can grab the material assembly group from the conveyor belt and transfer it to the detection position (i.e., the first detection position). The height detection and transfer mechanism is a mechanical gripper mechanism, which includes a detection frame and detection grippers. The detection frame is mounted on a single-box assembly and is equipped with a transverse slide rail. The transverse slide rail is suspended on the detection frame and runs along the output direction of the material assembly. A sliding seat is slidably installed on the transverse slide rail, and a longitudinal slide rail is mounted on the sliding seat. A gripper frame is slidably installed on the longitudinal slide rail, and a detection gripper is installed on the gripper frame. The detection gripper can be adjusted and displaced in both the transverse and longitudinal directions, thereby accurately transferring the aforementioned material assembly group to the first detection position.

[0032] Combination Figures 1 to 4 As shown, the working principle of the first feeding unit is as follows: Material 1: Material 1 is fed onto the conveyor belt through the first feeding mechanism; Material 2: The turntable is normally in the docking position of the first feeding mechanism. After rotating 90 degrees, it switches to the docking position of the second feeding mechanism. At this time, the second feeding mechanism loads material 2 into material 1 located on the turntable or conveyor belt. After the assembly is completed, the turntable rotates 90 degrees in the opposite direction to return to normal. Height inspection: The material assembly group is transferred to the first inspection position through the height inspection transfer mechanism for the first inspection to determine whether the product is qualified.

[0033] The second feeding unit is used to supply material three. The second feeding unit includes a rotary unloading mechanism, a rotary positioning mechanism, and a second transmission rail. The second transmission rail is a conveyor belt, which is on the same horizontal plane as the conveyor belt of the first feeding unit and can be connected. The rotary unloading mechanism and the rotary positioning mechanism are respectively placed on both sides of the second transmission rail and correspond to the same position; that is, the rotary unloading mechanism and the rotary positioning mechanism are arranged opposite each other. The rotary positioning mechanism is used to intercept and position the material assembly group on the second transmission rail, and the rotary unloading mechanism is used to feed material three into the material assembly group. In this embodiment, there are two rotary unloading mechanisms and two rotary positioning mechanisms. The two rotary unloading mechanisms are arranged sequentially along the output direction of the second transmission rail, and thus the two rotary positioning mechanisms are distributed one-to-one with the two rotary unloading mechanisms to achieve the feeding of two different sizes of material three. Material three is a spherical object, and the two rotary unloading mechanisms respectively feed spherical objects with diameters of 8cm and 10cm.

[0034] like Figure 5 and Figure 6 As shown, the rotary positioning mechanism includes a positioning baffle and a baffle motor. The positioning baffle is bent towards the starting end of material conveying, with one end serving as a drive end. This drive end is connected to the baffle motor and is driven by the baffle motor to rotate onto the second transmission rail, thereby intercepting the material assembly group. In this embodiment, the positioning baffle is L-shaped, with its long side connected to the baffle motor and driven by the baffle motor to rotate towards the second transmission rail, thereby intercepting the material assembly group that is being transmitted via the second transmission rail. It should be noted that because the rotary positioning mechanism corresponds one-to-one with the rotary unloading mechanism, the material assembly group that has been intercepted by the positioning baffle is located at the material loading position of the rotary unloading mechanism.

[0035] like Figure 6 and Figure 7As shown, the rotary feeding mechanism includes a feeding hopper, a rotating plate, and a staggered pusher plate. The feeding hopper is an open-top container with a feeding outlet at its bottom. The rotating plate is rotatably mounted inside the feeding hopper and positioned near the feeding outlet. The rotating plate has multiple feed ports distributed at equal angles, each with a size and shape adapted to the material, allowing only one material to pass through at a time. A feeding guide plate is installed at the feeding port outlet to guide the material output from the feeding port. The staggered pusher plate has a feeding port that is normally staggered from the output material. Driven by a staggered cylinder, the staggered pusher plate slides back and forth along the discharge direction, causing the material to fall from the feeding port and accurately into the positioned material assembly group, thus completing the assembly of the material. Specifically: the rotating plate is driven to rotate by a rotating mechanism, which includes a rotary motor, a belt drive pulley set and a driven shaft; the driven shaft passes through the bottom of the hopper and is installed inside the hopper; the rotating plate is connected and linked with the driven shaft; the output shaft of the rotary motor is linked with the driven shaft through the belt drive pulley set, that is: the rotary motor drives the driven shaft to rotate by the belt drive pulley set, thereby driving the rotating plate.

[0036] It should be noted that: such as Figure 8 As shown, the end of the second transmission rail furthest from the first feeding unit is the second detection position. This second detection position uses a photographic detection method to inspect the semi-finished product after assembly of material three. A detection positioning component and a detection camera are provided at the second detection position. The camera is suspended above the second detection position by the detection frame, with its shooting end looking down at the semi-finished product. The detection positioning component includes two opposing clamping arms, which are driven by clamping cylinders to achieve effective clamping and positioning of the semi-finished product. Specifically, at the second detection position, the two opposing clamping arms can clamp and position the semi-finished product being transported on the second transmission rail. Then, the camera takes a picture of the semi-finished product from above. The picture can be compared with a preset pattern (in which the quantity of material three is set) to determine whether the semi-finished product is qualified.

[0037] like Figure 8 As shown, the semi-finished product that has been inspected at the second detection position is transferred to the third transmission rail via the second transmission rail. The third transmission rail is at the same height as the second transmission rail in the second feeding unit and is closely connected to it.

[0038] like Figure 8 and Figure 9As shown, downstream of the second feeding unit is a quality control unit, which includes a waste ejection mechanism, an interception mechanism, a waste discharge pipe, and the aforementioned third transmission rail. The waste ejection mechanism and the interception mechanism are fixed on the same side of the third transmission rail, and the waste discharge pipe is assembled on the other side of the third transmission rail, corresponding to the waste ejection mechanism. That is, the semi-finished product is transported on the third transmission rail, intercepted and positioned by the interception mechanism, and then pushed from the third transmission rail into the waste discharge pipe by the waste ejection mechanism to remove defective products.

[0039] like Figure 8 and Figure 9 As shown, the waste ejection mechanism and the interception mechanism are sequentially arranged along the transmission direction of the third transmission rail. The interception mechanism includes an interception baffle and an interception cylinder. The output end of the interception cylinder is connected to the interception baffle, and the interception baffle is driven by the interception cylinder to be pushed onto the third transmission rail to intercept the semi-finished product. The waste ejection mechanism includes a pusher arm and a pusher cylinder. The output end of the pusher cylinder is connected to the pusher arm and drives the pusher arm to push the intercepted semi-finished product towards the waste discharge pipe, thereby pushing the semi-finished product (which has been presumed to be defective) towards the waste discharge pipe, thus removing the defective product. Specifically: the interception baffle has an interception surface, which is located near the waste ejection mechanism. In this embodiment, the interception baffle is L-shaped and bent towards the waste ejection mechanism. The pusher arm has a pushing surface, which is a plane facing the pushing direction. In this embodiment, the pusher arm is a frame structure with an opening on one side. The L-shaped interception baffle is located at the notch of the pusher arm. Based on the above structural design, the semi-finished product is transported on the third transmission rail. If the semi-finished product has been determined to be a defective product at the first detection position and / or the second detection position, the intercepting cylinder drives the intercepting baffle to intercept the defective semi-finished product. Then, the pushing cylinder drives the pushing arm to push the defective semi-finished product from the detection transmission slide rail to the waste discharge pipe, and then the waste discharge pipe is used to discharge it.

[0040] like Figure 8 As shown, the waste discharge pipe can be a chute or guide rail for discharging unqualified semi-finished products. Its inlet is connected to the third transmission rail, and the other end is guided into the unqualified product recycling container.

[0041] like Figure 8 and Figure 9As shown, a weight detection guide rail is arranged adjacent to the third transmission rail and is connected to the third transmission rail. A third detection position is set at the end away from the third transmission rail. The third detection position is used for weight detection. A weighing cylinder is installed at this position. This weighing cylinder is a cylinder with an integrated weighing sensor. The weighing end of the weighing cylinder is recessed into the detection position. When detection is required, the weighing cylinder drives the weighing end to extend out of the semi-finished product mounting plane for weighing. In order to accurately transfer the semi-finished product to the third detection position, a weight detection transfer mechanism is configured. This mechanism can grab the semi-finished product and transfer it to the third detection position for weighing. Specifically, the weight detection and transfer mechanism includes a gripper, a translation slide rail, and a telescopic slide rail. The translation slide rail is fixed to the top surface of the double-opening operation box via a slide rail frame. A translation slide seat is slidably installed on the translation slide rail. The telescopic slide rail is installed on the translation slide seat. The gripping cylinder is slidably connected to the telescopic slide rail via the telescopic slide seat. The gripper is driven by the gripping cylinder to perform gripping operations.

[0042] like Figure 8 and Figure 9 As shown, in order to accurately grasp the semi-finished product, a grasping and positioning mechanism is also provided next to the interception mechanism. The grasping and positioning mechanism includes a stop claw and a stop cylinder. The stop claw is connected to the output end of the stop cylinder and is driven by the stop cylinder to extend toward the third transmission rail to stop the semi-finished product.

[0043] like Figure 8 and Figure 9 As shown, a third feeding mechanism is provided next to the third detection position. This third feeding mechanism is used to supply material four. In this embodiment, material four is fitted with a cover, which is fastened to the open end of material one to close material one. Specifically, the third feeding mechanism includes a third feeding conductor, a third feeding pusher plate, and a third feeding bin; the third feeding conductor is connected to the third feeding bin, and material four is guided down along the inner wall of the third feeding conductor and pushed into the third feeding bin by the third feeding pusher plate.

[0044] like Figure 8 and Figure 9 As shown, material four in the third feeding bin is adsorbed and fed onto material one using a feeding suction cup mechanism. The feeding suction cup mechanism includes a lifting guide rail, a telescopic cylinder, and a suction cup. The lifting guide rail is vertically arranged and installed on a double-opening operating box. A lifting slide is slidably mounted on the lifting guide rail, and a telescopic cylinder is installed on the lifting slide. The output end of the telescopic cylinder is connected to the suction cup cylinder. In this embodiment, the semi-finished product after weighing and detection remains stationary at the third detection position. Material four is adsorbed and moved to the third detection position by the feeding suction cup mechanism and assembled onto the semi-finished product to obtain the finished product.

[0045] like Figure 1 and Figure 10 As shown, the output unit is located downstream of the quality control unit. This output unit uses a product gripping mechanism to grip finished products from the quality control unit to the output unit, and utilizes a nine-grid material bin and a waste conveyor belt for waste removal. The nine-grid material bin is a material rack with multiple material slots arranged in a matrix. Each material slot has a clearance hole on its bottom. Each material slot in the nine-grid material bin is equipped with a switch, the control end of which extends through the clearance hole into the material slot. That is, when a finished product is placed in the nine-grid material bin, it will press against the control end of the switch, thus indicating that the material bin is occupied by a finished product. The waste conveyor belt is a transport channel for outputting defective finished products and is located near the nine-grid material bin.

[0046] like Figure 10 As shown, the aforementioned product gripping mechanism is a three-dimensional gripping tool with three-axis motion. It includes a three-axis linkage assembly and a gripping assembly. The three-axis linkage assembly is mounted on the top of the double-opening operating box via a three-axis frame, and is positioned higher than the nine-grid material bin and waste conveyor belt to facilitate the transfer of finished products between the nine-grid material bin and the waste conveyor belt. The three-axis linkage assembly includes an X-axis slide rail, a Y-axis slide rail, and a Z-axis slide rail. The X-axis slide rail is mounted via the three-axis frame, and the two X-axis slide rails are arranged parallel to each other, forming a double X-axis slide rail design. An X-axis slide block is mounted on each X-axis slide rail, and the Y-axis slide rail is installed between the two X-axis slide blocks, enabling the Y-axis slide rail to slide along the X-axis. A Y-axis slide block is slidably connected to the Y-axis slide rail, and the Z-axis slide rail is connected to the Y-axis slide block and driven by the Y-axis slide block to slide along the Y-axis. A Z-axis slide block is slidably mounted on the Z-axis slide rail, and the gripping assembly is mounted on the Z-axis slide block and driven by the Z-axis slide block to slide along the Z-axis. The gripping assembly includes a claw and a drive motor. The drive motor is mounted on the Z-axis slide block, and the claw is mounted on its output end. The drive motor drives the claw to perform a gripping action, thereby gripping the finished product, transferring the defective finished product to the waste conveyor belt, and transferring the qualified finished product to the nine-grid material bin.
