Description

Technical Field

[0001] This invention belongs to the field of assembly equipment technology, and particularly relates to an assembly equipment for a grinder. Background Technology

[0002] Grinding mills are commonly used equipment in food processing, chemical production, and material preparation. Their structure typically includes multiple components such as the main body, upper shell, lower shell, and steel shell. The assembly precision and connection strength of each component directly affect the working stability and service life of the grinding mill. With the continuous growth of downstream industries' demand for grinding mills, the market's requirements for grinding mill production efficiency and product consistency are increasing. As a key process in the grinding mill production process, the level of automation in the assembly stage has become a core bottleneck restricting industrial upgrading.

[0003] Currently, the assembly of grinding machines in China is mainly carried out manually or semi-automatically, which has several prominent problems: First, manual loading, positioning, pressing, and locking operations rely on the operator's experience, and are prone to human error, leading to misalignment of components. For example, misalignment between the grinding machine body and the upper shell not only affects the subsequent screw tightening effect but may also cause component damage, reducing the product qualification rate. Second, the assembly processes are carried out separately, requiring manual transfer of workpieces between different workstations, which not only increases labor intensity but also leads to chaotic production rhythms, making it difficult to form a continuous production process and resulting in low production efficiency. Third, the consistency of manual operation is poor, and key parameters such as assembly force and locking torque of the same batch of products fluctuate greatly, resulting in unstable quality of finished grinding machines and increased after-sales maintenance costs. Fourth, with rising labor costs, the production costs of the traditional manual assembly mode continue to increase, and the market competitiveness of enterprises is gradually weakening.

[0004] Although some companies have attempted to introduce automated equipment for single processes, such as independent feeding or locking devices, these devices mostly operate in isolation, lacking coordination with other processes. Manual intervention is still required for process transitions and workpiece transfers, failing to fundamentally solve the problems of fragmented assembly processes and low automation. Therefore, developing a system capable of fully automated assembly of grinders, with coordinated processes and high assembly precision, has become an urgent need for grinder manufacturers. Summary of the Invention

[0005] The purpose of this invention is to provide an assembly device for a grinder to solve the problems mentioned in the background art.

After the positioning block clamps the steel ring and positions it on the grinding machine body, the pressure head presses down on the top of the steel ring and tightens the steel ring around the outside of the grinding machine body.

[0015] In a further embodiment of the present invention, the feeding mechanism includes a ninth support frame, which is fixed on the machine frame, and a feeding belt is conveyed on the ninth support frame for placing the assembled finished product.

[0016] The beneficial effects of this invention are: 1. The equipment uses a conveyor belt as its core transport carrier. Along the conveying direction, the frame integrates a complete set of equipment, including a grinding mill body feeding mechanism, a detection mechanism, an upper shell feeding mechanism, a clamping mechanism, a locking mechanism, a tilting mechanism, a steel shell assembly mechanism, and a finishing mechanism, forming a continuous assembly production line. From the initial feeding of the grinding mill body to upper shell assembly, locking, workpiece tilting, steel shell fitting, lower shell assembly, final locking, and finished product finishing, all processes are automatically completed through mechanical structures, completely breaking the limitations of traditional decentralized production models. Simultaneously, the carrier moves synchronously with the conveyor belt, and each mechanism works collaboratively according to a preset rhythm, standardizing and rhythmizing the assembly process of each workpiece. This effectively shortens the assembly cycle of a single grinding mill, significantly improves overall production efficiency, and can meet the needs of large-scale batch production.

[0017] 2. The equipment's inspection mechanism uses a CCD camera to precisely detect the loading position of the grinder body, promptly identifying and removing misaligned workpieces to prevent subsequent assembly misalignment issues. The loading mechanism employs a precise transmission structure with a slide rail-carrier combination, coupled with clamping components to ensure stable gripping and positioning of parts, guaranteeing the alignment accuracy of the upper and lower shells with the grinder body. The clamping mechanism uses a pressure head with elastic cushioning to achieve reliable clamping while preventing damage to parts from compression. The locking mechanism uses a robotic arm to precisely complete the locking operation with a screwdriver, working in conjunction with a cylinder-driven clamping block to stably hold the grinder body, ensuring consistent screw tightening torque and preventing over-tightening or under-tightening. The precise movements and coordinated operation of these mechanisms effectively reduce errors caused by human operation, significantly improving the assembly accuracy and quality stability of the same batch of products, significantly reducing the product defect rate, and minimizing raw material waste and rework costs.

[0018] 3. The equipment adopts a modular design concept, with the upper and lower shell feeding mechanisms having identical structures, as do the first and second clamping mechanisms, and the first and second locking mechanisms. This design not only reduces the types and number of equipment parts, lowering equipment R&D, production, and procurement costs, but also facilitates operators' rapid familiarization with the operating procedures of different mechanisms, reducing training costs. Simultaneously, mechanisms with identical structures can share spare parts, reducing spare parts inventory. When equipment malfunctions, maintenance personnel can quickly locate the problem and complete repairs, shortening equipment downtime and reducing maintenance costs.

[0019] 4. The equipment frees workers from tedious, repetitive manual labor such as loading, positioning, clamping, and locking. Only a small number of operators are needed for auxiliary tasks such as equipment monitoring and tray replenishment, significantly reducing the labor intensity of operators. At the same time, the automated assembly process reduces direct contact between workers and workpieces, lowering the risk of workplace injuries due to improper operation. Furthermore, the equipment operates stably, reducing noise and dust pollution during production, creating a safer and more comfortable working environment for operators, and helping to improve employee morale and the company's production management level.

[0020] 5. The equipment's carrier can be adapted and adjusted to fit the structure of different specifications of grinder bodies. Key components such as the feeding mechanism and clamping assembly can also meet the assembly requirements of different sized parts by replacing appropriate parts, effectively improving the equipment's applicability and enabling it to meet the production needs of various types of grinders. Furthermore, the equipment's modular structure facilitates subsequent upgrades to individual mechanisms or the addition of new process modules based on production process optimization or new functional requirements, providing excellent scalability and convenient conditions for future production upgrades.

[0027] This embodiment provides an assembly device for a grinder, including: A frame 1 is provided, on which a conveyor belt 10 is horizontally fixed. The conveyor belt 10 is driven by a drive motor to rotate at a constant speed. Several carriers 11 for placing the grinding body are fixed at equal intervals along the conveying direction on the conveyor belt 10. The carriers 11 are provided with positioning grooves that are adapted to the shape of the grinding body, which can form a stable limit on the grinding body. The carriers 11 move synchronously and smoothly with the conveyor belt 10, realizing the continuous transfer of workpieces between various assembly processes, avoiding the low efficiency and workpiece collision problems caused by manual handling. On the frame 1 and located outside the conveyor belt 10, the following components are arranged in sequence along the conveying direction: grinding body feeding mechanism 1A, detection mechanism 1B, upper shell feeding mechanism 1C, first pressing mechanism 1D, first locking mechanism 1E, flipping mechanism 1F, steel shell assembly mechanism 1G, lower shell feeding mechanism 1H, second pressing mechanism 1I, second locking mechanism 1J, and unloading mechanism 1K. The actions of each mechanism are coordinated and linked through the PLC control system to ensure consistent assembly rhythm. The grinding machine body feeding mechanism 1A automatically picks up the grinding machine body and feeds it onto the carrier 11, replacing manual feeding and improving feeding efficiency and positioning accuracy. The detection mechanism 1B detects the feeding position of the grinding machine body in real time and promptly removes workpieces with misaligned positions to avoid subsequent assembly misalignment. The upper shell feeding mechanism 1C accurately picks up the upper shell and places it on top of the grinding machine body, ensuring accurate alignment between the upper shell and the body. The first pressing mechanism 1D tightly presses the upper shell onto the grinding machine body, providing a stable foundation for subsequent locking processes. The first locking mechanism 1E automatically tightens the screws, ensuring a firm connection between the upper shell and the body. The flipping mechanism... 1F drives the grinder body to complete a smooth 180° rotation, eliminating the need for manual flipping and improving operational safety and efficiency. The steel shell assembly mechanism 1G precisely fits the steel shell onto the outside of the grinder body, improving the fit of the steel shell assembly. The lower shell feeding mechanism 1H feeds the lower shell to the other end of the grinder body, achieving symmetry in the assembly of the upper and lower shells. The second pressing mechanism 1I presses the lower shell tightly against the grinder body, ensuring the stability of the lower shell assembly. The second locking mechanism 1J locks the lower shell to the grinder body with screws, ensuring a firm assembly of the entire machine. The unloading mechanism 1K automatically transfers the assembled finished product to the unloading belt 81, achieving orderly collection of the finished product.

[0028] In this embodiment, the upper shell feeding mechanism 1C and the lower shell feeding mechanism 1H adopt the same structural design, the first clamping mechanism 1D and the second clamping mechanism 1I have the same structure, and the components and operating principles of the first locking mechanism 1E and the second locking mechanism 1J are the same. This standardized design reduces the types and inventory of equipment parts, lowers equipment manufacturing costs and maintenance difficulty, and at the same time facilitates operators to quickly master the operation methods of each mechanism, shortens the training cycle, and improves production management efficiency.

[0029] In this embodiment, the grinding machine body feeding mechanism 1A further includes a first support frame 12 and a second support frame 13, both of which are fixed to the preset installation position of the frame 1 by bolts, ensuring a firm connection that is not easily loosened. A feeding belt 14 is conveyed on the first support frame 12 via a transmission roller and a drive motor. The feeding belt 14 rotates at a uniform speed in the horizontal direction. Main body fixing blocks 15 are fixed at intervals on the feeding belt 14, and each main body fixing block 15 has a slot adapted to the grinding machine body. The grinding machine body is vertically inserted into the slot, effectively preventing the body from tipping over or shifting during feeding. A horizontally arranged first slide rail 16 is fixed to the second support frame 13 by bolts. A first slide 17 is slidably mounted on the first slide rail 16, and the first slide 17 is driven by a servo motor to move laterally along the first slide rail 16. A second slide 19 is slidably mounted on the first slide 17, and the second slide 19 performs longitudinal lifting and lowering movements. The second slide 19 is fixedly equipped with a clamping assembly 100 at its bottom. This clamping assembly 100 includes a drive motor and symmetrically arranged grippers 63. The drive motor drives the grippers 63 to open and close via a gear transmission mechanism. During operation, the first slide 17 and the second slide 19 work together to move the clamping assembly 100 directly above the main body fixing block 15. Driven by the drive motor, the grippers 63 open and enclose the top of the grinder body. Then, the grippers 63 close to clamp the body. The first slide 17 and the second slide 19 work together to precisely transfer the body into the positioning slot of the carrier 11, and the grippers 63 open to complete the placement. The entire loading process is automated, with a positioning accuracy of ±0.1mm, improving efficiency by more than three times compared to manual loading, and effectively avoiding workpiece contamination caused by manual contact.

[0030] In this embodiment, the detection mechanism 1B further includes a third support frame 20, which is fixed to the frame 1 by expansion bolts to ensure stable support. A second slide rail 21 is horizontally fixed at the top of the third support frame 20, and a third slide 22 is slidably mounted on the second slide rail 21. The third slide 22 is driven by a cylinder to move along the second slide rail 21, and the detection position can be adjusted to adapt to different specifications of the grinder body. A CCD camera 23 is fixed at the bottom of the third slide 22 by a bracket. The lens of the CCD camera 23 is vertically facing the carrier 11 of the conveyor belt 10, and the camera is electrically connected to the image recognition system. When the carrier 11 carries the grinder body to the detection station, the conveyor belt 10 stops running, and the third slide 22 drives the CCD camera 23 to move directly above the body. The camera quickly captures an image of the body and transmits it to the image recognition system. The system compares the image with a preset standard image to determine whether the body has any problems such as positional deviation or tilting. If the inspection is successful, conveyor belt 10 continues to operate; if the inspection fails, the system triggers an alarm and controls subsequent mechanisms to pause operation, while simultaneously feeding back information about the defective workpiece to the control system for timely handling by operators. This inspection method offers a fast response time, effectively preventing subsequent assembly failures caused by improper placement of the main body and reducing the scrap rate.

[0031] In this embodiment, the upper shell feeding mechanism 1C further includes a feeding platform 30, which is fixedly mounted on the outside of the frame 1 by a bracket, maintaining a reasonable distance from the conveyor belt 10 to facilitate the replacement of the material trays 31. Several material trays 31 containing upper shells are placed in layers on the feeding platform 30. Each material tray 31 has a matrix-like placement groove, and the upper shells are orderly embedded in the placement groove to prevent mutual collision and wear. The upper shell feeding mechanism 1C also includes a fourth support frame 32, which is fixed to the frame 1 by bolts. A third slide rail 33 is horizontally fixed to its top, and a fourth slide 34 slides slidably on the third slide rail 33. The fourth slide 34 is driven by a servo motor to move laterally along the third slide rail 33. The bottom of the fourth slide 34 is fixed with a clamping assembly 100 identical to that of the grinding machine body feeding mechanism 1A. During operation, the fourth slide 34 moves the clamping assembly 100 above the material tray 31. The grippers 63 of the clamping assembly 100 open and clamp the upper shell under the drive of the motor. The fourth slide 34 then moves the upper shell directly above the carrier 11 of the conveyor belt 10. The mounting base descends and precisely places the upper shell onto the positioning boss on the top of the grinder body. The grippers 63 then open to complete the loading. This mechanism achieves automated and precise loading of the upper shell, increasing efficiency by two times compared to manual loading, and avoiding scratches on the upper shell caused by manual placement.

[0032] In this embodiment, the first pressing mechanism 1D further includes a fifth support frame 40, which is fixed to the frame 1 by welding and bolts, making it structurally stable and able to withstand the impact force during the pressing process. A vertically downward-facing first cylinder 41 is fixed to the top of the fifth support frame 40 via a cylinder seat. A pressure head 42 is installed at the bottom output end of the first cylinder 41 via a floating joint. An elastic rubber pad is attached to the bottom of the pressure head 42, providing good elastic cushioning. When the carrier 11 carries the grinding machine body with the upper shell to the pressing station, the conveyor belt 10 stops operating. The piston rod of the first cylinder 41 drives the pressure head 42 to move vertically downwards. The elastic rubber pad at the bottom of the pressure head 42 first contacts the top of the upper shell. As the piston rod continues to descend, the rubber pad undergoes elastic deformation, evenly transmitting the pressing force to the upper shell, ensuring a tight fit between the upper shell and the grinding machine body. The pressing force can be adjusted to a preset value (range 5-10N) via a pressure regulating valve to avoid excessive pressure causing damage to components or insufficient pressure resulting in a loose fit. After clamping is completed, the piston rod of the first cylinder 41 drives the pressure head 42 to quickly reset, and the conveyor belt 10 continues to operate. The clamping action of this mechanism is smooth and the pressure control is precise, providing a stable assembly foundation for subsequent screw tightening and making the upper shell less prone to loosening after tightening.

[0033] In this embodiment, the first locking mechanism 1E further includes a multi-degree-of-freedom manipulator 50, which is fixed to the frame 1 by a mounting base. A screwdriver is detachably mounted on its end effector, and the screwdriver is connected to an automatic feeding mechanism to achieve automatic screw supply. The first locking mechanism 1E also includes a sixth support frame 51, which is symmetrically arranged on both sides of the conveyor belt 10. Each sixth support frame 51 is equipped with a horizontally oriented second cylinder 52 fixed by a cylinder seat. The output end of the second cylinder 52 is fixed with an arc-shaped clamping block 53 by a connecting block, and an anti-slip silicone pad is attached to the inner side of the clamping block 53. When the carrier 11 reaches the locking position, the second cylinders 52 on both sides activate simultaneously, pushing the clamping block 53 towards the center until it is pressed tightly against the outer wall of the grinder body. This frictional force firmly clamps and fixes the body, preventing rotation during locking. Subsequently, the robotic arm 50 moves the screwdriver to the preset screw hole position. Driven by the motor, the screwdriver rotates, while the automatic feeding mechanism feeds the screw to the screwdriver head. The screwdriver then descends, screwing the screw into the threaded holes of the upper shell and the main body until the preset torque is reached. After locking, the screwdriver resets, the second cylinder 52 moves the clamping block 53 back, and the conveyor belt 10 continues to operate. This mechanism achieves automated and precise screw locking, increasing efficiency by four times compared to manual locking, and avoiding the uneven torque problem caused by manual locking.

[0034] In this embodiment, the flipping mechanism 1F further includes a seventh support frame 60, which is fixed on the frame 1. A third cylinder 61 is horizontally arranged and fixed on its top by a bracket. The output end of the third cylinder 61 is connected to a flipping cylinder 62 through a flange. A symmetrical gripper 63 is installed on the output end of the flipping cylinder 62 through a connecting shaft. The inner side of the gripper 63 is provided with an arc-shaped groove adapted to the grinding body, and the groove is provided with anti-slip texture. When the carrier 11 carrying the workpiece arrives at the flipping station, the third cylinder 61 actuates, pushing the flipping cylinder 62 and the gripper 63 closer to the workpiece. The gripper 63 closes under the drive mechanism of the flipping cylinder 62, firmly clamping the workpiece. Then, the third cylinder 61 moves the workpiece away from the carrier 11, disengaging it from the carrier 11's positioning slot. Next, the flipping cylinder 62 drives the gripper 63 to rotate the workpiece 180° around a horizontal axis. The flipping process is smooth and without shaking, and the rotation speed can be adjusted via a speed control valve. After flipping, the third cylinder 61 pushes the workpiece back into the carrier 11, the gripper 63 opens, and the third cylinder 61 drives the flipping cylinder 62 back to its original position, allowing the conveyor belt 10 to continue operating. This mechanism achieves automated workpiece flipping with high accuracy, avoiding the risk of workpiece falling and damage caused by manual flipping, thus improving operational safety and efficiency.

[0035] In this embodiment, the steel shell assembly mechanism 1G further includes an eighth support frame 70, which is fixed to the frame 1. A fourth slide rail 71 is vertically fixed to the top of the eighth support frame 70. A fifth slide 72 is slidably mounted on the fourth slide rail 71 and is driven by a servo motor to move up and down along the fourth slide rail 71. A guide rail is horizontally fixed to one side of the fifth slide 72, and a sixth slide 73 is slidably mounted on the guide rail. The sixth slide 73 is driven by a cylinder to move laterally along the guide rail. A drive motor is fixed to the bottom of the sixth slide 73, and the bottom output end of the drive motor is connected to a pressure head 42 via a coupling. The bottom of the pressure head 42 has an annular pressure surface adapted to the top of the steel shell. A fourth cylinder 74 is fixed to the bottom of the fifth slide 72 via a bracket. A positioning block 75 is horizontally fixed to the output end of the fourth cylinder 74. The positioning block 75 has an arc-shaped positioning surface adapted to the inner wall of the steel shell, and the positioning blocks 75 are symmetrically arranged on both sides directly below the pressure head 42. During operation, the fourth cylinder 74 pushes the positioning block 75 to open, and the steel shell is fed between the positioning blocks 75 by the feeding mechanism. Then, the fourth cylinder 74 drives the positioning block 75 to close, clamping and positioning the steel shell. Next, the fifth slide 72 and the sixth slide 73 work together to drive the pressure head 42 and the positioning block 75 to move synchronously, aligning the steel shell with the external assembly position of the grinder body. The fifth slide 72 drives the steel shell downward to fit over the outside of the body. Then, the positioning block 75 opens and resets under the action of the fourth cylinder 74. The drive motor drives the pressure head 42 to rotate and apply downward pressure, tightening the steel ring around the outside of the grinder body, ensuring a tight and gapless fit between the steel shell and the body. This mechanism achieves automated and precise assembly of the steel shell, increasing assembly efficiency by 3 times compared to manual assembly, and effectively ensuring the coaxiality of the assembled steel shell.

[0036] In this embodiment, the unloading mechanism 1K further includes a ninth support frame 80, which is bolted to the end of the frame 1. The top of the ninth support frame 80 is connected to a drive motor via a bearing seat, and a unloading belt 81 is mounted thereon. The conveying direction of the unloading belt 81 is perpendicular to the conveyor belt 10, and the height of the unloading belt 81 is adapted to the height of the carrier 11 of the conveyor belt 10, facilitating the smooth transfer of finished products. When the sensor of the unloading mechanism 1K detects that the carrier 11 carrying the assembled finished product has arrived at the unloading station, the conveyor belt 10 stops operating, and the finished product is transferred to the collection box at the end of the unloading belt 81 by clamping, achieving orderly collection of finished products. This unloading process requires no manual intervention, avoiding scratches on finished products caused by manual handling, and simultaneously achieving continuous transfer of finished products, improving the efficiency of subsequent packaging processes.
