Description

Technical Field

[0001] The invention relates to the field of bicycle assembly, in particular to a bicycle hoisting production line. Background Art

[0002] In the bicycle production process, there are many problems with the traditional bicycle assembly method. In the early days, bicycle assembly mainly relied on manual operation, and workers needed to carry, position and assemble each component one by one. This method is labor-intensive and inefficient, and due to the uncertainty of manual operation, it is difficult to ensure the consistency of product quality. With the continuous increase in bicycle market demand, the traditional manual assembly method can no longer meet the requirements of large-scale production.

[0003] In order to improve production efficiency, some companies began to introduce simple production line equipment. However, early production line equipment had many limitations. In terms of hoisting bicycle parts, traditional hoisting production lines lacked a mechanism to effectively position bicycle handlebars. Since bicycle handlebars are irregular in shape and relatively slender, they are prone to shaking and offset during the hoisting process. This makes it difficult to accurately install the handlebars in the corresponding position in the subsequent assembly process.

[0004] On the one hand, the shaking and deviation of the handlebars will affect the installation process of subsequent vehicle parts. Workers need to spend a lot of time and energy to adjust the position of the handlebars during the subsequent assembly process, which not only reduces the efficiency of assembly, but also increases labor costs. Moreover, frequent adjustments may cause unnecessary friction and collision between the handlebars and the frame, thereby damaging the surface of the vehicle parts and affecting the appearance quality of the bicycle.

[0005] On the other hand, lack of accurate positioning may also lead to deviations in the angle and position of the handlebar installation. Such deviations may affect the handling performance of the bicycle, such as causing inflexible steering and reduced hand comfort when riding. Once the product enters the market, these problems may cause consumer dissatisfaction and reduce the brand's reputation and market competitiveness.

[0006] In terms of fixing parts, the traditional fixing method often uses rigid connection, which is easy to cause damage to the parts. Moreover, due to the differences in size and shape of bicycle parts of different models, the traditional fixing method is difficult to adapt to the diverse needs of parts, reducing the versatility of the production line.

DETAILED DESCRIPTION

[0033] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0034] refer to Figures 1 to 8 , a bicycle hoisting production line, including a slide seat 3 connected to a production line slide rail 2, and also including:

[0035] The lower end of the slide 3 is fixedly connected with a main motor 4, the output end of the main motor 4 is downwardly arranged and fixedly connected with a main board 8, the lower end of the main board 8 is fixedly connected with a bracket 9, a cylinder 10 is arranged in the middle of the bracket 9, the output end of the cylinder 10 is downwardly arranged and fixedly connected with a backing plate 13, a rubber pad 14 is arranged at the lower end of the backing plate 13, a support pad 15 is arranged below the bracket 9, the rubber pad 14 is abutted against the upper end of the cross beam of the vehicle part 1, and the support pad 15 is abutted against the lower end of the cross beam of the vehicle part 1, and a positioning mechanism 16 is arranged on one side of the bracket 9, and the positioning mechanism The structure 16 includes an auxiliary motor 17, a secondary motor 21, a secondary shaft 18, two claws 19, two connecting frames 32, two main racks 37, two main gears 40, two auxiliary racks 42 and two claws 45. The auxiliary motor 17 is arranged above the bracket 9, the secondary motor 21 is arranged beside the auxiliary motor 17, the secondary shaft 18 is coaxially connected to the output end of the auxiliary motor 17, the upper ends of the two claws 19 are fixedly connected to the auxiliary shaft 18, and the two connecting frames 32 are respectively arranged on the side away from the two claws 19 (such as Figure 7As shown in the figure, one of the connecting frames 32 is fixedly connected to the auxiliary motor 17, and when the secondary motor 21 is started, it drives the two connecting frames 32 to move upward, and the two main racks 37 are respectively slidably arranged beside the two claws 19, and the main racks 37 are arranged below the bracket 9. The two main gears 40 are respectively arranged beside the two main racks 37, and the two auxiliary racks 42 are respectively arranged on the side of the two main gears 40 away from the two main racks 37. The main rack 37 drives the auxiliary rack 42 to move through the main gear 40, and the two clasps 45 are respectively fixedly connected to the two auxiliary racks 42. After the claws 19 move, they abut against the lower end of the handlebar of the vehicle component 1, and after the clasps 45 move, they abut against the upper end of the handlebar of the vehicle component 1.

[0036] When the device is in operation, the operator first hangs the vehicle part 1 on the upper end of the support pad 15, and then the cylinder 10 is started and pushes the rubber pad 14 to abut against the crossbeam of the vehicle part 1, thereby completing the preliminary positioning of the vehicle part 1.

[0037] After the crossbeam of the bicycle component 1 is positioned, the operator adjusts the placement angle of the handlebar of the bicycle component 1 and starts the auxiliary motor 17 at the same time. After the auxiliary motor 17 is started, it will drive the two claws 19 to deflect in the direction of the handlebar of the bicycle component 1, and then the secondary motor 21 is started and drives the two claws 19 to move upward. After the two claws 19 move upward, they will hold the lower end of the handlebar of the bicycle component 1 from bottom to top. In this process, the two claws 19 will drive the two main gears 40 to rotate through the two main racks 37. After the main gears 40 rotate, they will drive the claws 45 to abut the lower end of the handlebar of the bicycle component 1 from top to bottom through the auxiliary rack 42. At this time, the bicycle component 1 is completely positioned, thereby preventing the handlebar of the bicycle component 1 from shaking when the slide seat 3 moves along the slide rail 2 of the production line, thereby affecting the subsequent assembly work.

[0038] In order to reduce the load force on the output end of the main motor 4 without affecting the rotation of the main board 8, the following features are specifically provided:

[0039] The outer coaxial rotating sleeve of the slide 3 is provided with a main turntable 6, the outer coaxial fixed sleeve of the main board 8 is provided with a secondary turntable 7, and a plurality of connecting rods 5 are arranged in an array at equal intervals along the circumferential direction on one side of the main turntable 6 close to the secondary turntable 7, and the upper end of the connecting rod 5 is fixedly connected to the main turntable 6, and the lower end is fixedly connected to the secondary turntable 7. When the main motor 4 drives the main board 8 to rotate, the rotation of the main board 8 will drive the secondary turntable 7 to rotate, and the secondary turntable 7 will drive the main turntable 6 to rotate through the plurality of connecting rods 5. In this process, the rotational connection between the main turntable 6 and the slide 3 and the setting of the connecting rod 5 can share the load force borne by the output end of the main motor 4, making the rotation of the main board 8 more stable, and at the same time reducing the risk of damage that may occur to the output end of the main motor 4 due to excessive load, ensuring the normal operation of the bicycle hoisting production line, and improving the service life and work efficiency of the equipment.

[0040] In order to achieve non-rigid resistance between the rubber pad 14 and the crossbeam of the vehicle component 1, the following features are also specifically provided:

[0041] A plurality of buffer springs 12 are arranged on one side of the abutment plate 13 close to the rubber pad 14. The upper end of the buffer spring 12 is fixedly connected to the abutment plate 13, and the lower end is fixedly connected to the hard shell at the upper end of the rubber pad 14. The buffer spring 12 is coaxially sleeved with a limit shaft 11. The lower end of the limit shaft 11 is fixedly connected to the hard shell at the upper end of the rubber pad 14, and the upper end is slidably connected to the abutment plate 13. When the cylinder 10 is started to push the abutment plate 13 to move downward, the abutment plate 13 transmits force to the rubber pad 14 through the buffer spring 12. The buffer spring 12 is elastic. When the rubber pad 14 abuts against the cross beam of the vehicle component 1, the buffer spring 12 will be compressed and deformed, thereby realizing the non-rigid abutment between the rubber pad 14 and the cross beam of the vehicle component 1. The setting of the limit shaft 11 ensures that the buffer spring 12 will not deviate or twist during the compression and rebound process, thereby ensuring the stability of the buffering effect. This non-rigid offset method can avoid damage to the cross beam of the vehicle component 1 due to rigid contact when positioning the cross beam of the vehicle component 1, and can also better adapt to cross beams of different sizes and shapes of the vehicle component 1, thereby improving the versatility of the device and the protection capability of the vehicle component 1.

[0042] In order to supplement the specific structure of the positioning mechanism 16, the following features are also specifically provided:

[0043] The positioning mechanism 16 also includes two main bevel teeth 22, two driven bevel teeth 23, two bevel gear racks 24 and four side seats 25. The two main bevel teeth 22 are coaxially arranged in a symmetrical state. The two main bevel teeth 22 are coaxially fixedly connected to the output end of the secondary motor 21. The four side seats 25 are respectively arranged on the side of the secondary motor 21. The two bevel gear racks 24 are respectively rotatably connected to the two main bevel teeth 22. The two bevel gear racks 24 are respectively fixedly connected to the adjacent side seats 25. The two driven bevel teeth 23 are respectively rotatably connected to the two bevel gear racks 24, and the driven bevel teeth 23 are meshed with the main bevel teeth 22. After the secondary motor 21 is started, the secondary motor 21 will drive the driven bevel teeth 23 to rotate through the main bevel teeth 22, thereby transmitting the power of the secondary motor 21 to the subsequent transmission components, providing a power basis for the movement of the connecting frame 32 and the claw 19, further improving the power transmission structure of the positioning mechanism 16, and ensuring the normal operation of the positioning mechanism 16.

[0044] In order to drive the connecting frame 32 to move, and then drive the claw 19 through the connecting frame 32, the following features are also specifically provided:

[0045] The positioning mechanism 16 also includes four main pulleys 26, four secondary pulleys 27, four extrusion gears 28, four extrusion racks 29, four extrusion frames 30 and four buffer tension springs 31. The four main pulleys 26 are rotatably connected to the four side seats 25 respectively. The two main pulleys 26 located on one side of the same connecting frame 32 are coaxially fixedly connected to the corresponding driven bevel teeth 23. A secondary pulley 27 rotatably connected to the side seat 25 is arranged below each main pulley 26. The secondary pulley 27 is connected to the main pulley 26 through a belt. The gears 28 are rotatably arranged on the side of the four side seats 25 close to the connecting frame 32, the extrusion gear 28 is coaxially fixedly connected with the secondary pulley 27, the four extrusion racks 29 are slidably connected with the four side seats 25, the extrusion racks 29 are meshed with the extrusion gear 28, the four extrusion frames 30 are respectively fixedly connected with the four extrusion racks 29, the extrusion frames 30 are fixedly connected with the connecting frame 32, and the four buffer tension springs 31 are respectively arranged at the lower ends of the four extrusion frames 30, the upper ends of the buffer tension springs 31 are fixedly connected with the extrusion frames 30, and the lower ends are fixedly connected with the bracket 9. After the driven bevel gear 23 rotates, the driven bevel gear 23 will drive the secondary pulley 27 to rotate through the main pulley 26, and the secondary pulley 27 will drive the extrusion rack 29 to move through the extrusion gear 28, and the extrusion rack 29 will drive the connecting frame 32 to move after the movement, and the movement of the connecting frame 32 will drive the claw 19 to move in the vertical direction, thereby ensuring that the claw 19 positions the handlebar of the vehicle part 1 from bottom to top. The buffer tension spring 31 can play a buffering role during the movement of the connecting frame 32 to avoid damage to the device due to sudden force changes.

[0046] In order to form a connection between the claw 19 and the main rack 37 when the claw 19 moves upward, the following features are also provided:

[0047] The positioning mechanism 16 also includes two main buckle plates 20 and two auxiliary buckle plates 38. The two main buckle plates 20 are respectively fixedly connected to the lower ends of the two claws 19, and the two auxiliary buckle plates 38 are respectively fixedly connected to the lower ends of the two main racks 37. When the claws 19 are deflected from the inclined state to the vertical state, the upper ends of the main buckle plates 20 abut against the lower ends of the auxiliary buckle plates 38. When the auxiliary motor 17 is started, the two claws 19 are driven to deflect toward the handlebar of the vehicle component 1. When the claws 19 reach the vertical state, the upper ends of the main buckle plates 20 abut against the lower ends of the auxiliary buckle plates 38, and a connection is formed between the claws 19 and the main racks 37. This connection mode enables the claws 19 to drive the main racks 37 to move upward while moving upward, thereby realizing the linkage between the claws 19 and the main racks 37, providing the necessary conditions for the subsequent main gear 40 to drive the auxiliary racks 42 to move and the claws 45 to position the handlebars of the vehicle component 1, thereby ensuring the overall coordination of the device.

[0048] In order to facilitate the main rack 37 to reset itself after it moves upward when the main clasp plate 20 and the auxiliary clasp plate 38 are subsequently separated, the following features are also provided:

[0049] The positioning mechanism 16 further includes two positioning tooth seats 33, two top plates 34, two lifting springs 35 and two bottom plates 36. The two positioning tooth seats 33 are respectively arranged beside the two main racks 37 and are fixedly connected to the bracket 9 (such as Figure 8 As shown in the figure, the main rack 37 is slidably connected with the positioning gear seat 33, the two top plates 34 are respectively fixedly connected with the upper ends of the two positioning gear seats 33, the two bottom plates 36 are respectively fixedly connected with the upper ends of the two main racks 37, and the lifting spring 35 is arranged on the side of the top plate 34 close to the bottom plate 36, one end of the lifting spring 35 is fixedly connected with the top plate 34, and the other end is fixedly connected with the bottom plate 36. When the claw 19 moves upward and drives the main rack 37 to move upward through the main buckle plate 20 and the auxiliary buckle plate 38, the main rack 37 slides upward on the positioning gear seat 33, and the lifting spring 35 between the top plate 34 and the bottom plate 36 will be compressed. When the main buckle plate 20 and the auxiliary buckle plate 38 are separated, the lifting spring 35 will restore the elastic deformation, generate a downward elastic force, push the bottom plate 36 to move downward, thereby driving the main rack 37 to move downward to achieve reset.

[0050] In order to drive the auxiliary rack 42 to move downward, the auxiliary rack 42 can reset itself when the main pinch plate 20 and the auxiliary pinch plate 38 are separated, the following features are also provided:

[0051] The positioning mechanism 16 further includes two positioning wheel seats 39, two reset springs 41, two transfer sliders 43 and two guide rails 44. The two positioning wheel seats 39 are respectively fixedly connected to the lower end of the bracket 9, the two main gears 40 are respectively rotatably connected to the two positioning wheel seats 39, the two transfer sliders 43 are respectively fixedly connected to the two auxiliary racks 42, the two guide rails 44 are respectively arranged on the sides of the two auxiliary racks 42 and are fixedly connected to the lower end of the bracket 9, the two transfer sliders 43 are respectively slidably connected to the two guide rails 44, one end of the two reset springs 41 is fixedly connected to the two transfer sliders 43, and the other end is fixedly connected to the lower end of the bracket 9. When the main rack 37 moves upward and drives the auxiliary rack 42 to move downward through the main gear 40, the transfer slider 43 slides downward along the guide rail 44, and the reset spring 41 will be stretched. When the main clasp plate 20 and the auxiliary clasp plate 38 are separated and the main rack 37 is reset, the auxiliary rack 42 loses the driving effect of the main gear 40. Under the tension of the reset tension spring 41, the transfer slider 43 will slide upward along the guide rail 44, driving the auxiliary rack 42 to move upward to achieve reset. The setting of the positioning wheel seat 39 ensures the stable rotation of the main gear 40, the cooperation of the guide rail 44 and the transfer slider 43 ensures the linearity and stability of the movement of the auxiliary rack 42, and the reset tension spring 41 provides power for the reset of the auxiliary rack 42, so that the positioning mechanism 16 can quickly return to the initial state after completing a positioning action, and prepare for the next positioning.

[0052] The working principle of the device is that in the initial state, the production line slide rail 2 is in a standby state, and the slide seat 3 is located at the starting position of the guide rail 44. The operator carries the bicycle component 1 to the side of the device, and first hangs the component 1 on the upper end of the support pad 15. At this time, the cylinder 10 is started, and its output end pushes the abutment plate 13 downward. The abutment plate 13 transmits force to the rubber pad 14 through the buffer spring 12. The rubber pad 14 abuts against the upper end of the crossbeam of the component 1, and the support pad 15 abuts against the lower end of the crossbeam of the component 1, completing the preliminary positioning of the crossbeam of the component 1. The existence of the buffer spring 12 realizes the non-rigid abutment between the abutment plate 13 and the crossbeam of the component 1, avoiding damage to the crossbeam of the component 1.

[0053] After the crossbeam of the vehicle component 1 is positioned, the operator manually adjusts the placement angle of the handlebar of the vehicle component 1 to make it in a suitable position. Then, the auxiliary motor 17 is started, and the output end of the auxiliary motor 17 drives the secondary shaft 18 to rotate, and the two claws 19 fixedly connected to the secondary shaft 18 deflect toward the direction of the handlebar of the vehicle component 1. Then, the secondary motor 21 is started, and the output end of the secondary motor 21 drives the main bevel gear 22 to rotate, and the main bevel gear 22 drives the driven bevel gear 23 meshing therewith to rotate. The driven bevel gear 23 drives the main pulley 26 fixedly connected to the coaxial line to rotate, and the main pulley 26 drives the secondary pulley 27 to rotate through the belt, and the secondary pulley 27 drives the extrusion gear 28 to rotate, and the extrusion gear 28 meshes with the extrusion rack 29, so that the extrusion rack 29 slides on the side seat 25, and the extrusion rack 29 drives the extrusion frame 30 to move, and the extrusion frame 30 drives the connecting frame 32 to move upward, thereby moving the two claws 19 upward.

[0054] In the process of the claw 19 being required to move upward, when the claw 19 is deflected from the inclined state to the vertical state, the upper end of the main clasp plate 20 is aligned with the lower end of the auxiliary clasp plate 38, the claw 19 is connected to the main rack 37, and the claw 19 drives the main rack 37 to move upward. When the main rack 37 moves upward, it drives the main gear 40 meshing therewith to rotate, the main gear 40 drives the auxiliary rack 42 to move downward, and the auxiliary rack 42 drives the claw 45 to move downward until the claw 45 abuts against the upper end of the handlebar of the vehicle component 1, and the claw 19 abuts against the lower end of the handlebar of the vehicle component 1, thereby completing the positioning of the handlebar of the vehicle component 1.
