Description

Technical Field

[0001] The utility model relates to the technical field of automatic assembly, in particular to a device for automatically inserting pins into rubber latches. Background Art

[0002] Rubber has good elasticity and deformation ability, while metal has high rigidity and stability. In some applications, it is necessary to have both elastic and rigid characteristics, such as rubber shock absorbers in automotive suspension systems. The combination of rubber and metal can achieve this requirement. Rubber provides shock absorption and energy absorption characteristics, and metal provides support and stability characteristics. The combination of the two can achieve the complementary advantages of materials, thus meeting various functions and requirements of the product.

[0003] In the traditional assembly process of metal pins and rubber latches, since there is an interference fit between rubber and metal and the accuracy requirements for the assembled finished products are relatively high, it is necessary to first perform pre-pressing and initial positioning on the rubber latches. In this process, a worker needs to hold the rubber latch with one hand and squeeze the metal pin into the assembly hole of the rubber latch with the other hand. After completing the pre-pressing and initial positioning, with the cooperation of a hand press, the metal pin and the rubber latch are assembled through multiple aligning and pressing operations.

[0004] The existing technology has the following defects: In the traditional assembly process, workers need to apply sufficient pressure while keeping their hands stable. Long-term operation may cause hand fatigue and discomfort. And due to the high cooperation requirements, workers also need to spend a lot of energy on accurate positioning and repeated calibration. This process takes a long time, increasing the production cycle and cost, and the production efficiency is low, unable to meet the needs of large-scale production, so there is room for improvement. Summary of the Utility Model

[0005] In order to solve the above-mentioned technical problems, the utility model provides a device for automatically inserting pins into rubber latches to solve the technical problems of long positioning and calibration processes and low production efficiency in the traditional assembly process of rubber latches and metal pins.

[0006] The utility model is realized through the following technical solutions:

[0007] A device for automatically inserting pins into rubber latches includes a frame, a feeding mechanism, a pressing mechanism, a stamping mechanism, and an operating platform. The operating platform and the feeding mechanism are arranged on the frame. The feeding mechanism includes a vibrating bowl and a guiding chute. The guiding chute is inclined and is used to convey the metal pins in the vibrating bowl to the operating platform. The pressing mechanism is used to press the rubber latch located on the operating platform. The stamping mechanism includes a stamping cylinder and a punch member. The punch member pushes the metal pin into the assembly hole of the rubber latch along the operating platform under the drive of the stamping cylinder.

[0008] Preferably, a rubber positioning block is further provided on the operation platform, and the rubber positioning block is arranged in a shape matching with the side surface of the rubber lock.

[0009] Preferably, the pressing mechanism includes a pressing cylinder and a pressing joint. The pressing joint is detachably arranged at the output end of the pressing cylinder, and the pressing joint is arranged in a shape matching with the top surface of the rubber lock.

[0010] Preferably, a metal positioning block is further provided on the operation platform. The metal positioning block is arranged opposite to the discharge port of the material guiding groove, and the side of the metal positioning block close to the metal pin is arranged as a straight wall.

[0011] Preferably, a U-shaped groove is further provided on the operation platform. The U-shaped groove is arranged between the discharge port of the material guiding groove and the metal positioning block, and the metal pin is press-fitted into the assembly hole of the rubber lock along the U-shaped groove.

[0012] Preferably, a connecting arm is provided on the operation platform. The rubber positioning block is inserted and installed on the connecting arm, and a spring is connected between the rubber positioning block and the connecting arm.

[0013] Preferably, the U-shaped groove is detachably installed on the operation platform.

[0014] Preferably, a buffer block is vertically arranged at one end of the operation platform away from the punch part. The buffer block is used to buffer the collision between the metal pin and the operation platform after the press-fitting is completed.

[0015] The beneficial effects of the present utility model are as follows:

[0016] 1. Through the arrangement of the vibrating disk and the material guiding groove, the metal pin can be accurately sent to the operation platform, reducing the need for manual intervention. The pressing mechanism ensures the stability of the lock, enabling the stamping mechanism to quickly and accurately push the metal pin into the assembly hole; the automated design not only reduces the time for positioning and calibration, but also reduces the errors caused by manual operation, improving the assembly accuracy; the stability and precision of the equipment reduce the rework rate caused by improper assembly, further improving the overall efficiency and output value of the production line, and can meet the needs of large-scale production;

[0017] 2. By setting the rubber positioning block, the rubber lock is fixed at a definite position, preventing the movement or inclination of the rubber lock due to external force or vibration during the assembly process, ensuring the accuracy of subsequent pressing and stamping operations, and ensuring that the metal pin can accurately enter the assembly hole. By setting the side of the metal positioning block close to the metal pin as a straight wall, when the metal pin is discharged, it can be accurately guided to the predetermined position, preventing its deviation or dislocation. At the same time, the metal positioning block with a straight wall structure provides a general guiding solution for different forms of metal pins, ensuring the adaptability to diverse products.

[0018] 3. Through the matching design of the pressing joint with the top surface shape of the rubber lock, it is ensured that during the pressing process, the force is applied evenly and consistently, maximizing the contact area between the pressing joint and the rubber lock, and helping to prevent the rubber lock from deforming during the pressing process. By adopting a detachable pressing joint design, different-shaped pressing joints can be quickly replaced to adapt to various types of rubber locks. The detachable setting of the U-shaped groove enables the quick replacement of the U-shaped groove according to the assembly requirements of different products to fit different-sized or -shaped assembly holes.

Obviously, the described embodiments are only a part of the embodiments of this utility model, rather than all of the embodiments. Based on the embodiments in this utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the protection scope of this utility model.

[0028] It should be noted that similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0029] The following will, in conjunction with the accompanying drawings, elaborate in detail some implementation manners of this utility model. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0030] To further elaborate on the technical means and effects adopted by this utility model to achieve the intended utility model purpose, the following will, in conjunction with the accompanying drawings and preferred embodiments, elaborate in detail on the specific implementation manners, structures, features and their effects according to this utility model.

[0031] Please refer to Figures 1-4 , a device for automatically installing pins for a rubber lock, including a frame 1, a feeding mechanism 2, a pressing-down mechanism 3, a stamping mechanism 4, and a working platform 5. The working platform 5 and the feeding mechanism 2 are arranged on the frame 1. The feeding mechanism 2 includes a vibration bowl 21 and a feeding chute 22. The feeding chute 22 is inclined and is used to convey the metal pins 6 in the vibration bowl 21 to the working platform 5. The pressing-down mechanism 3 is used to press the rubber lock 7 located on the working platform 5. The stamping mechanism 4 includes a stamping cylinder 41 and a punching part 42. The punching part 42, under the drive of the stamping cylinder 41, pushes the metal pin 6 along the working platform 5 into the assembly hole of the rubber lock 7.

[0032] The operating principle of the automatic pin-installing device in this utility model is as follows:

[0033] The vibrating bowl 21 makes the metal pins 6 evenly distributed in the bowl through vibration, avoiding the accumulation and jamming of the metal pins 6 during the feeding process; the vibration frequency and amplitude can be adjusted to adapt to different types and sizes of metal pins 6; the feeding chute 22 is inclined, and by the action of gravity and vibration, the metal pins 6 in the vibrating bowl 21 are smoothly conveyed to the working platform 5; the design of the feeding chute 22 ensures the stability of the metal pins 6 during the conveying process, reducing the risk of dropping and damage; the feeding mechanism 2 accurately sends the metal pins 6 to the working platform 5 to ensure that each metal pin 6 can be operated subsequently at the correct position; the function of the pressing mechanism 3 is to press the rubber lock 7 located on the working platform 5. Through pressing, the rubber lock 7 is kept stable during the assembly process, avoiding position deviation caused by external interference, thus ensuring the accuracy of the subsequent stamping process; the punch 42 is driven by the cylinder to quickly and accurately push the metal pin 6 into the assembly hole of the rubber lock 7. Due to the action of the pressing mechanism 3, the rubber lock 7 remains stable during the stamping process, ensuring that the metal pin 6 can accurately enter the predetermined position.

[0034] In the traditional manual assembly process, the positioning and calibration of the rubber lock 7 and the metal pin 6 often require a lot of time and manpower. Each step may involve multiple adjustments and inspections, increasing the possibility of errors. After using this automatic pin loading device, the feeding mechanism 2 accurately sends the metal pins 6 to the working platform 5 through the vibrating bowl 21 and the feeding chute 22, reducing the need for manual intervention. The pressing mechanism 3 ensures the stability of the rubber lock 7, enabling the stamping mechanism 4 to quickly and accurately push the metal pin 6 into the assembly hole; the automated design not only reduces the time for positioning and calibration, but also reduces the errors caused by human operation, improving the accuracy of assembly; through the automated assembly equipment, all links in the production process are efficiently connected; the coordinated work of the feeding mechanism 2, the pressing mechanism 3 and the stamping mechanism 4 significantly reduces the assembly time of each rubber lock 7. Compared with the traditional manual assembly, the automated equipment can process more rubber locks 7 per unit time, greatly improving the production efficiency; in addition, the stability and accuracy of the equipment reduce the rework rate caused by improper assembly, further improving the overall efficiency and output value of the production line. The application of the automatic pin loading device makes the production process smoother, can meet the needs of large-scale production, and enhances the competitiveness of the enterprise.

[0035] To ensure the accuracy of subsequent pressing and stamping operations and ensure that the metal pin 6 can accurately enter the assembly hole, in one embodiment, a rubber positioning block 8 is further provided on the working platform 5, and the rubber positioning block 8 is arranged in cooperation with the side shape of the rubber lock 7. When the rubber lock 7 is placed on the working platform 5, the rubber positioning block 8 can effectively fix the rubber lock 7 in a definite position, preventing the rubber lock 7 from moving or tilting due to external force or vibration during the assembly process, ensuring the accuracy of subsequent pressing and stamping operations, and ensuring that the metal pin 6 can accurately enter the assembly hole; the application of the rubber positioning block 8 enables the operator or equipment not to spend time on fine adjustment and inspection during the assembly of the rubber lock 7. The presence of the positioning block provides great convenience for rapid assembly, making the entire assembly process more efficient. The automated equipment reduces the need for manual intervention and further improves production efficiency.

[0036] To prevent the rubber lock 7 from deforming during the pressing process and ensure its shape and structural integrity, in one embodiment, the pressing mechanism 3 includes a pressing cylinder 31 and a pressing joint 32. The pressing joint 32 is detachably arranged at the output end of the pressing cylinder 31, and the pressing joint 32 is arranged in cooperation with the top surface shape of the rubber lock 7. The matching design of the pressing joint 32 and the top surface shape of the rubber lock 7 can ensure that during the pressing process, the force application is uniform and consistent, ensuring the maximum contact area between the pressing joint 32 and the rubber lock 7, so that the pressing force is evenly distributed, which helps to prevent the rubber lock 7 from deforming during the pressing process and ensures its shape and structural integrity; by adopting the detachable pressing joint 32 design, different-shaped pressing joints 32 can be quickly replaced to adapt to various types of rubber locks 7, enabling the equipment to easily respond to different production tasks, which helps to improve production efficiency and reduce production costs; the reasonable design of the cooperation between the pressing joint 32 and the top surface of the rubber lock 7 not only helps to apply the correct pressure but also avoids damage or scratches on the surface of the rubber lock 7 caused by poor contact. When the soft rubber material is under pressure and in contact with a pressing joint 32 with a suitable shape, the risk of damage caused by sharp edges or uneven pressure is reduced, and the service life of the product is extended.

[0037] To ensure that the metal pin 6 can accurately align with the assembly hole of the rubber lock catch 7 to be assembled and reduce the wear of the metal pin 6 during the assembly process, in one embodiment, a metal positioning block 9 is further provided on the operating platform 5. The metal positioning block 9 is disposed opposite to the discharge port of the material guiding groove 22, and the side of the metal positioning block 9 close to the metal pin 6 is provided with a straight wall. The straight wall design can effectively limit the lateral movement that may occur during the placement or transportation of the metal pin 6. The metal positioning block 9 with a straight wall can accurately guide the metal pin 6 to a predetermined position when the metal pin 6 is discharged, preventing it from being misaligned or displaced, thereby ensuring that the metal pin 6 can accurately align with the assembly hole of the rubber lock catch 7 to be assembled; the metal positioning block 9 with a straight wall structure provides a general guiding solution for different forms of metal pins 6. Whether the metal pin 6 is slender or short and wide, the straight wall can effectively guide it into the assembly position, providing guarantee for the adaptability of diversified products; the existence of the straight wall of the metal positioning block 9 helps to achieve good docking between the metal pin 6 and the hole of the rubber lock catch 7, ensuring that when the metal pin 6 enters the assembly hole, it can maintain the correct angle and position, reducing the assembly error and improving the overall accuracy of the assembly process; at the same time, the setting of the straight arm reduces the friction between the metal pin 6 and the metal positioning buckle during the stamping process, reducing the wear of the metal pin 6 during the assembly process.

[0038] To effectively prevent the metal pin 6 from deviating or tilting during the falling or pushing process and reduce the positioning and alignment time during the assembly process, in one embodiment, a U-shaped groove is further provided on the operating platform 5. The U-shaped groove is disposed between the discharge port of the material guiding groove 22 and the metal positioning block 9, and the metal pin 6 is press-fitted into the assembly hole of the rubber lock catch 7 along the U-shaped groove. The structural design of the U-shaped groove provides a good guiding channel for the metal pin 6. After the metal pin 6 flows out of the material guiding groove 22 and enters the U-shaped groove, due to the lateral constraints provided by the two side walls of the U-shaped groove on the metal pin 6, it effectively prevents the metal pin 6 from deviating or tilting during the falling or pushing process, ensuring that the metal pin 6 can smoothly and accurately enter the assembly hole of the rubber lock catch 7; the design of the U-shaped groove can also play a certain buffering role. When the metal pin 6 slides from the material guiding groove 22 into the U-shaped groove, it may generate an impact due to gravity and movement speed, and the edge of the U-shaped groove can reduce the impact of the metal pin 6 falling onto the operating platform 5, improving the service life of the metal pin 6 and avoiding damage caused by rapid falling; in addition, it can also reduce the impact during the hole-entry process and protect the structure of the rubber lock catch 7; since the U-shaped groove can guide the metal pin 6 directly towards the assembly hole, it reduces the positioning and alignment time during the assembly process, effectively improving the work efficiency, enabling the assembly to be completed in a shorter time, and at the same time reducing the need for manual intervention, further realizing automation and high efficiency.

[0039] The shapes and sizes of the rubber latches 7 may vary. To ensure adaptation to different products during the assembly process, in one embodiment, a connecting arm 10 is provided on the working platform 5. The rubber positioning block 8 is inserted and installed on the connecting arm 10, and a spring is connected between the rubber positioning block 8 and the connecting arm 10. The design of the connecting arm 10 and the spring provides the necessary flexibility. The movable characteristic of the connecting arm 10 enables the rubber positioning block 8 to automatically adjust its position according to the specific shape and size of the rubber latch 7, ensuring that the positioning block can always accurately fit against the side of the rubber latch 7, thus improving the assembly accuracy; the setting of the spring provides a preloading function for the rubber positioning block 8. During the assembly process, the spring will expand and contract according to the force on the rubber positioning block 8, ensuring that the rubber latch 7 can be firmly fixed on the working platform 5 under the pressure of the pressing mechanism 3, ensuring that the rubber latch 7 will not shift during pressing and stamping, thereby improving the assembly accuracy and reducing the probability of incorrect assembly.

[0040] To achieve rapid replacement of the U-shaped groove and adapt to assembly holes of different sizes or shapes, in one embodiment, the U-shaped groove is detachably installed on the working platform 5. The detachable design of the U-shaped groove enables the device to adapt to different specifications and types of rubber latches 7. According to the assembly requirements of different products, rapid replacement of the U-shaped groove can be achieved to adapt to assembly holes of different sizes or shapes. This flexibility enables the device to play a greater role in a production environment with multiple varieties and small batches; during the production process, if it is occasionally necessary to adjust the shape or inclination angle of the U-shaped groove to improve the assembly accuracy or efficiency, the detachable design allows the operator to quickly complete the adjustment without disassembling the entire device, avoiding waste of time and manpower and improving the overall efficiency of the production line.

[0041] In order to disperse and mitigate the impact between the metal pin 6 and the working platform 5 and reduce the possible wear, in one embodiment, a buffer block 11 is vertically provided at one end of the working platform 5 away from the punch member 42. The buffer block 11 is used to buffer the collision between the metal pin 6 and the working platform 5 after the press-fitting is completed. When the metal pin 6 is pushed into the assembly hole of the rubber buckle 7 by the stamping mechanism 4, without the buffer block 11, the metal pin 6 may directly contact the working platform 5 after the assembly is completed, resulting in a large impact force and posing a risk of damaging the structure of the metal pin 6. The introduction of the buffer block 11 helps to disperse and mitigate these impacts and reduces the possible wear. Repeated impacts over a long period may cause wear to the equipment, especially at the place where the working platform 5 contacts the metal pin 6. The buffer block 11 provides an isolation between the metal pin 6 and the working platform 5, which can extend the service life of the equipment and reduce the maintenance cost caused by wear. At the same time, when the metal pin 6 quickly contacts the working platform 5, a relatively large noise is usually generated, which has a great impact on the comfort of the working environment. The presence of the buffer block 11 can absorb part of the mechanical impact energy, thereby reducing the noise level and making the equipment run relatively quietly, creating a better working environment.

[0042] The above are only the preferred embodiments of the present invention, and do not impose any form of limitation on the present invention. Although the present invention has been disclosed above with the preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to the equivalent embodiments with equivalent changes within the scope of the technical solution of the present invention. However, as long as it does not depart from the content of the technical solution of the present invention, any brief modifications, equivalent changes and modifications made to the above embodiments according to the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
