Description

Technical Field

[0001] This utility model relates to the field of assembly machine technology, and in particular to a material picking, guiding and pressing mechanism based on an assembly machine platform. Background Technology

[0002] Assembly machines refer to specialized mechanical equipment platforms or workstations used to automatically or semi-automatically complete the assembly of product components. They are widely used in manufacturing industries such as electronics, automobiles, home appliances, medical devices, and consumer electronics.

[0003] Existing electronic product assembly equipment typically places the material handling mechanism, guiding mechanism, and pressing mechanism in different workstations or independent modules, with each unit relying on its own positioning reference for debugging. This separate layout results in the product undergoing multiple transfers and re-alignments during the process from material handling to pressing, leading to cumulative positioning errors between processes. This makes it difficult to guarantee the final assembly accuracy, and debugging requires repeated coordination of the positional consistency of multiple fixtures and mechanisms, which is time-consuming and difficult.

[0004] Because the picking, guiding, and pressing actions are executed sequentially and rely on the repeated movement of the main motion platform, the single assembly cycle time is long, making it impossible to achieve parallel or overlapping operations between processes. Furthermore, the overall production capacity is easily limited, making it difficult to meet the needs of high-speed automated production. While existing solutions such as multi-degree-of-freedom robotic arms, rotary tables, or complex linkage mechanisms can achieve multi-functional integration, their control systems are complex, requiring high-cost servo drives and algorithm support. Moreover, the numerous moving parts and large inertia make them prone to vibration and jitter. Long-term operation may lead to rapid decay of positioning accuracy, affecting product yield. Therefore, the inventors have proposed a picking, guiding, and pressing mechanism based on an assembly machine to solve the aforementioned technical problem of solving the reference positioning of picking, guiding, and pressing in the same process. Utility Model Content

[0005] In order to overcome the shortcomings mentioned above, the utility model aims to provide a technical solution that can solve the above problems.

[0006] A material handling, guiding, and pressing mechanism based on an assembly machine includes a mounting frame, a connecting frame, and a support frame. The support frame is located on the surface of the mounting frame. The surface of the mounting frame is provided with a moving device for assisting the movement of the support frame. The moving device includes a moving X-axis and a moving Z-axis, both of which are driven by a drive motor. The surface of the support frame is provided with a pressing device, which includes a first pressing cylinder and a second pressing cylinder. A positioning fixture is provided below the pressing device, which is used to position the second product. The bottom of the support frame is equipped with a gripper cylinder for assisting in product picking. One end of the gripper cylinder is connected to a gripper for picking up the first product. The surface of the support frame is connected to a guide assembly for assisting in product guidance and pressing. This structure guides the first product into the target hole or slot along the correct path by automatically correcting deviation during the initial pressing stage. This avoids product deformation, cracking, abnormal increase in pressing force, and damage to molds or fixtures caused by forced pressing. Without guidance, the pressing process is prone to lateral friction, which requires the first or second pressing cylinder to output greater thrust. By improving this structure, the degree of freedom of motion is constrained, reducing the lateral component force and concentrating the pressing force in the effective direction. This reduces the load fluctuation of the drive motor and cylinder, and reduces energy consumption and mechanical wear.

[0007] Furthermore, the guiding assembly includes a guide plate lifting cylinder, a guide plate telescopic cylinder, and a guide positioning plate. The surface of the guide positioning plate is provided with a plurality of locking blocks for assisting product positioning. The locking blocks are linearly arranged on the surface of the guide positioning plate, and one end of the guide positioning plate is connected to the surface of the positioning fixture. The guide plate lifting cylinder controls vertical movement, the guide plate telescopic cylinder controls horizontal forward and backward movement, and the guide positioning plate provides load-bearing and positioning functions. It works with the locking block for product auxiliary positioning. The locking block is installed in the groove on the surface of the guide positioning plate. The two ends of the groove are respectively provided with clearance slots. This clearance structure is used to reduce planar interference when removing or installing the locking block, so as to reduce obstruction when gripping the locking block.

[0008] Furthermore, one end of both the first and second pressing cylinders is provided with a guide block and a pressing shaft to assist in the product guiding and pressing, and the guide block and the pressing shaft are progressively connected. In the initial stage of press fitting, the guide block with a short stroke and moderate rigidity first contacts the product or fixture, and uses it to push the press fitting shaft for coarse alignment and posture correction, eliminating minor offsets or angular deviations. Then it facilitates the press fitting shaft to press. After the guide block completes the initial positioning, the press fitting shaft continues to descend, pressing the product into the target position to ensure the final assembly depth and perpendicularity.

[0009] Furthermore, the surface of the mounting frame is provided with linear guide rails for assisting the movement of the support frame. The linear guide rails have a symmetrical structure, which distributes the overall weight of the support frame and avoids overturning when the overall center of gravity shifts or the force is uneven. The mechanical symmetry is used to construct a basic motion platform, reducing the accuracy decay caused by load eccentricity, dynamic impact, and long-term wear in automated assembly.

[0010] Furthermore, the surface of the mounting frame is provided with a moving track for assisting the support frame in moving. The track structure has a certain elastic buffering capacity, which can reduce the impact force generated by the instantaneous impact from the start and stop of the drive motor, the action of the cylinder or external collision, and avoid the force of rigid movement being directly transmitted to the pressing shaft, the picking claw or the product itself.

[0011] Furthermore, one end of the connecting frame abuts against the surface of the support frame, and the surface of the connecting frame is respectively provided with a material picking moving cylinder and a material picking lifting cylinder; the material picking moving cylinder is driven in the horizontal direction to assist the material picking gripper in approaching / moving away from the product in the front-back or left-right direction, and the material picking lifting cylinder is driven in the vertical direction to control the lifting action, so as to facilitate picking up materials or placing them into the fixture. The two are integrated on the same connecting frame to form a compact two-dimensional motion unit. This structure can realize different steps in the same process.

[0012] Compared with the prior art, the beneficial effects of this utility model are: this mechanism can set up the material picking, guiding and pressing as a centralized structure. This structure ensures that the positions of the material picking, guiding and pressing products are consistent through a unified reference plane, reduces the errors caused by the separate layout of material picking, guiding and pressing, and reduces the difficulty of debugging the product positioning fixtures due to the need for multiple alignments of material picking, guiding and pressing. By simplifying and centralizing actions through a mechanism that combines linear movements in various directions, the machine can achieve product picking, guiding, and pressing. The control method is relatively common, and the stability of the mechanism is improved. In addition, this mechanism can combine with existing sensor detection technology to detect whether the product is in a horizontal state during picking, ensuring that the product is horizontal and upright before assembly, avoiding errors caused by assembling products that are not horizontally picked, and ensuring the consistency and yield of product assembly. The mechanism places, picks, guides, and presses simultaneously, ensuring that the mechanism completes picking, guiding, and assembly in a short time, increasing the machine's capacity.

Detailed Implementation

[0014] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0015] For this embodiment, please refer to Figures 1-8 The specific implementation of the material picking, guiding and pressing mechanism based on the assembly machine includes a mounting frame 1, a connecting frame 2 and a support frame 3. The support frame 3 is located on the surface of the mounting frame 1. The surface of the mounting frame 1 is provided with a moving device for assisting the movement of the support frame 3. The moving device includes a moving X-axis 4 and a moving Z-axis 5. Both the moving X-axis 4 and the moving Z-axis 5 are driven by a drive motor 6. The surface of the support frame 3 is provided with a pressing device, which includes a first pressing cylinder 7 and a second pressing cylinder 8. A positioning clamp 9 is provided below the pressing device, which is used to position the second product. The bottom of the support frame 3 is provided with a gripper cylinder 10 for assisting in product picking. One end of the gripper cylinder 10 is connected to a picking gripper 11, which is used to grip the first product. The surface of the support frame 3 is connected with a guide assembly for assisting in product guidance and pressing. This structure guides the first product into the target hole or slot along the correct path by automatically correcting deviation during the initial pressing stage. This avoids product deformation, cracking, abnormal increase in pressing force, and damage to molds or fixtures caused by forced pressing. Without guidance, the pressing process is prone to lateral friction, which requires the first pressing cylinder 7 or the second pressing cylinder 8 to output greater thrust. By improving this structure, the degree of freedom of motion is constrained, the lateral component force is reduced, and the pressing force is concentrated in the effective direction. This reduces the load fluctuation of the drive motor 6 and the cylinder, and reduces energy consumption and mechanical wear.

[0016] The guiding assembly includes a guide plate lifting cylinder 12, a guide plate telescopic cylinder 13, and a guide positioning plate 14. The surface of the guide positioning plate 14 is provided with a plurality of locking blocks 15 for assisting product positioning. The locking blocks 15 are linearly arranged on the surface of the guide positioning plate 14, and one end of the guide positioning plate 14 is connected to the surface of the positioning fixture 9. The guide plate lifting cylinder 12 controls the vertical movement, the guide plate telescopic cylinder 13 controls the horizontal forward and backward movement, the guide positioning plate 14 serves as a bearing and positioning function, and works with the locking block 15 for product auxiliary positioning. The locking block 15 is installed in the groove on the surface of the guide positioning plate 14, and the two ends of the groove are respectively provided with clearance slots. This clearance structure is used to reduce the planar interference formed when removing or installing the locking block 15, so as to reduce obstruction when gripping the locking block 15.

[0017] One end of the first pressing cylinder 7 and the second pressing cylinder 8 is provided with a guide block 21 and a pressing shaft 16 for assisting in product guiding and pressing. The guide block 21 and the pressing shaft 16 are progressively connected. In the initial stage of pressing, the guide block 21 with a short stroke and moderate rigidity first contacts the product or fixture, and uses it to push the pressing shaft 16 for coarse alignment and posture correction, eliminating minor offsets or angular deviations, and then facilitates the pressing shaft 16 to press. After the guide block 21 completes the initial positioning, the pressing shaft 16 continues to descend, pressing the product into the target position to ensure the final assembly depth and perpendicularity.

[0018] The surface of the mounting frame 1 is provided with linear guide rails 17 for assisting the movement of the support frame 3. The linear guide rails 17 have a symmetrical structure. This symmetrical structure distributes the overall weight of the support frame 3, preventing overturning when the overall center of gravity shifts or the force is uneven. The mechanical symmetry is used to construct a basic motion platform, reducing the accuracy decay caused by load eccentricity, dynamic impact, and long-term wear in automated assembly.

[0019] The surface of the mounting frame 1 is provided with a moving track 18 for assisting the support frame 3 in moving. The track structure has a certain elastic buffering capacity, which can reduce the impact force generated by the instantaneous impact from the start and stop of the drive motor 6, the action of the cylinder or external collision, and avoid the force of rigid movement being directly transmitted to the pressing shaft 16, the picking claw 11 or the product itself.

[0020] One end of the connecting frame 2 abuts against the surface of the support frame 3. The surface of the connecting frame 2 is respectively provided with a material picking moving cylinder 19 and a material picking lifting cylinder 20. The material picking moving cylinder 19 is driven in the horizontal direction to assist the material picking gripper 11 in approaching / moving away from the product in the front-back or left-right direction. The material picking lifting cylinder 20 is driven in the vertical direction to control the lifting action, which is convenient for picking up materials or placing them into the fixture. The two are integrated on the same connecting frame 2 to form a compact two-dimensional motion unit. This structure can realize different steps in the same process.

[0021] The key design features of this utility model are: this mechanism can set up material picking, guiding and pressing as a centralized structure. This structure ensures that the positions of the material picking, guiding and pressing products are consistent through a unified reference surface, reduces the errors caused by the separate layout of material picking, guiding and pressing, and reduces the difficulty of debugging the product positioning fixtures due to the need for multiple alignments of material picking, guiding and pressing. By simplifying and centralizing actions through a mechanism that combines linear movements in various directions, the machine can achieve product picking, guiding, and pressing. The control method is relatively common, and the stability of the mechanism is improved. In addition, this mechanism can combine with existing sensor detection technology to detect whether the product is in a horizontal state during picking, ensuring that the product is horizontal and upright before assembly, avoiding errors caused by assembling products that are not horizontally picked, and ensuring the consistency and yield of product assembly. The mechanism places, picks, guides, and presses simultaneously, ensuring that the mechanism completes picking, guiding, and assembly in a short time, increasing the machine's capacity.

[0022] The operation process of this utility model is as follows: The external vibratory feeder (not shown) feeds the product ① to the receiving position. The fiber optic sensor on the positioning groove above the picking moving cylinder 19 detects the product ①. The picking moving cylinder 19 pushes the product ① out of the misalignment. The picking lifting cylinder 20 below pushes it upward. The moving X-axis 4 moves to above the receiving position. The gripper picking cylinder 10 opens in both positions to grip the product ①. At the same time, the first pressing cylinder 7 and the second pressing cylinder 8 of the dual positions extend to the receiving position to ensure that the gripper picking cylinder 10 of the dual positions is at the same height as the product ①. The gripper picking cylinder 10 cooperates with the picking gripper 11 to close and grip the product. This gripping step is to grip two products ① at the same time. Then, the Z-axis 5 is moved to raise the product to a certain height, while the X-axis 4 is moved to be directly above the positioning fixture 9 used to place product ②. The Z-axis 5 is moved downward to a distance of 3-5mm directly above product ②. The guide plate lifting cylinder 12 moves downward, and the guide plate telescopic cylinder 13 extends to ensure that the guide positioning plate 14 is aligned with the product being picked up. The gripper cylinder 10 for picking up product ① opens in both positions, and at the same time, the first pressing cylinder 7 and the second pressing cylinder 8 in both positions move downward, driving the guide block 21 and the pressing shaft 16 used for pressing to move downward. The pressing shaft 16 contacts the top surface of product ①, and the pressing force completes the pressing assembly of product ① and product ② on the guide positioning plate 14. After completion, the next cycle can continue.

It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the scope of protection of the present invention.
