Description

Technical Field

[0001] This utility model relates to the field of watch strap processing technology, specifically to an automatic arrangement device for single watch straps. Background Technology

[0002] In the watch strap production process, the arrangement and assembly of individual strap links is a crucial step. Traditional methods rely heavily on manual labor, where individual strap links are removed one by one and arranged in a specific order. This method has several drawbacks. Firstly, manual operation is inefficient and cannot meet the demands of large-scale production. As market demand for watch straps continues to increase, the speed of manual arrangement cannot keep pace with production. Secondly, the consistency and accuracy of manual operation are difficult to guarantee. Factors such as human fatigue and lack of concentration can easily lead to errors in the arrangement of individual strap links, thus affecting product quality, increasing the defect rate, and raising production costs.

[0003] To address the issue of manual strap arrangement, some companies have adopted semi-automatic equipment, but these devices still have significant drawbacks. For example, existing single-strap arrangement devices have poor adaptability to individual straps, cannot adjust parameters such as feeding speed, arrangement order, and receiving frequency, lack versatility and flexibility, and cannot adapt to different production needs. Furthermore, existing single-strap arrangement devices are not precise enough in conveying and positioning individual straps during the arrangement process, easily leading to strap jamming and misalignment, further affecting production efficiency and product quality. Therefore, the inventors have invented an automatic single-strap arrangement device. Utility Model Content

[0004] The purpose of this invention is to provide an automatic single-stripe arrangement device. This device features a simple structure and reasonable design. Parameters such as the feeding speed, arrangement order, and receiving frequency of each single strap can be set on the human-machine interface of a PLC controller. The PLC controller controls the device in real time based on these parameters to adapt to different production needs, improve production efficiency, meet the requirements of large-scale production, ensure the accuracy and consistency of single-stripe arrangement, effectively reduce the defect rate, and improve product quality. The automated production process of this device reduces reliance on manual labor, lowers labor costs, and reduces material waste and rework costs caused by defective products, thus reducing production costs and solving the problems mentioned in the aforementioned technical background.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic single-strand watch strap arrangement device, comprising a working platform and a feeding mechanism, an arrangement mechanism, and a positioning mechanism disposed on the working platform, wherein the arrangement mechanism is located between the feeding mechanism and the positioning mechanism, the feeding mechanism includes a vibratory feeder and a feeding track disposed on the vibratory feeder, the vibratory feeder being fixed to the working platform, the arrangement mechanism including a support assembly and a drive assembly, an arrangement assembly, and a receiving plate disposed on the support assembly, wherein the arrangement assembly is located between the drive assembly and the receiving plate, a sensor is fixed on the receiving plate, the sensor being located at the end of the feeding track away from the vibratory feeder, the support assembly including a support platform, two symmetrically arranged supports being fixed on the upper surface of the support platform, the drive assembly including a first motor and a wheel connected to the output end of the first motor, the arrangement assembly including a first slide rail fixed to the upper surface of the support platform, and a sliding arrangement mechanism being slidably disposed on the first slide rail. The moving block and the push plate located on one side of the moving block are equipped with an auxiliary wheel at the end of the moving block away from the push plate. The auxiliary wheel is in contact with the wheel disk. Two guide rods are provided between the moving block and the push plate. The two guide rods are fixed on two supports respectively. The two ends of the moving block are slidably set on the two guide rods respectively. Therefore, the moving block can slide on the first slide rail and the two guide rods simultaneously.

A push bar is fixed at the end of the push plate away from the moving block. The positioning mechanism includes a fixed base and a second slide rail and a second motor fixed on the fixed base. The second slide rail and the second motor are distributed at both ends of the fixed base. A lead screw driven by the second motor is provided on the second slide rail. A receiving plate is provided on the lead screw. The receiving plate is in contact with the end of the receiving plate away from the arrangement assembly and can be translated along the surface of the receiving plate to receive the single watch strap output from the receiving plate.

The PLC controller is electrically connected to the feeding mechanism, the arranging mechanism and the positioning mechanism respectively, receives the signals fed back by the sensors, and controls the operation of each component according to the preset program. The PLC controller is also used to provide power to the feeding mechanism, the arranging mechanism and the positioning mechanism.

[0007] Preferably, the support platform is fixed to the upper end face of the working platform, and the first motor is fixed to the lower end face of the support platform.

[0008] Preferably, the wheel and the first motor are designed to be non-coaxial, and the wheel is located above the support platform.

[0010] Preferably, the receiving plate is fixed to the upper surface of the working platform, and the upper surface of the receiving plate forms an input port. The sensor is located directly above the input port and is used to detect whether there is a single watch strap in the input port.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model provides an automatic single-strand watch strap arrangement device. The device includes a working platform and a feeding mechanism, an arrangement mechanism, and a positioning mechanism mounted on the platform. A protective shell is fixed on the working platform, and a PLC controller is installed on the protective shell. The overall structure is simple and reasonably designed. The arrangement mechanism includes a support component and a drive component, an arrangement component, and a receiving plate mounted on the support component. The arrangement component is located between the drive component and the receiving plate. A sensor is fixed on the receiving plate and located at the end of the feeding track away from the vibrating plate. A sensor is also located at the end of the feeding track to detect whether the single watch strap is being output normally. If any abnormality such as blockage occurs, the PLC controller will receive a signal and issue an alarm. A track groove is provided on the feeding track, and an input port is provided on the receiving plate. Both the track groove and the input port are recessed designs. During the conveying process, the single watch strap sinks into the track groove and the input port, which can effectively prevent the single watch strap from shifting during the conveying process. This device is highly practical.

[0015] 2. The positioning mechanism in this utility model includes a fixed base and a second slide rail and a second motor fixed on the fixed base. The second slide rail and the second motor are distributed at both ends of the fixed base. A lead screw driven by the second motor is provided on the second slide rail, and a receiving plate is provided on the lead screw. Multiple positioning grooves are formed on the upper surface of the receiving plate. The position and shape of the positioning grooves correspond to the arrangement order of the single watch straps, ensuring that the single watch straps can be accurately placed in the predetermined position. The second motor drives the receiving plate to move continuously to the designated position, so that the designated positioning groove on it corresponds to the end position of the input port, and receives the single watch straps, so that the single watch straps can be accurately delivered to the receiving plate, avoiding jamming and offset of the single watch straps.

[0016] 3. In operation, the operator can interact with the device through the PLC controller. The operator can set parameters such as the feeding speed, arrangement order and receiving frequency of a single strap on the human-machine interface of the PLC controller. The PLC controller controls the device in real time according to these parameters to adapt to different production needs. Therefore, this device is suitable for widespread use.

[0017] 4. This utility model significantly shortens the arrangement time of a single watch strap by automating feeding, arrangement, and positioning. Compared with manual arrangement, the production efficiency of this device can be increased by several times or even dozens of times, meeting the needs of large-scale production. It ensures the accuracy and consistency of the arrangement of single watch straps, effectively reducing the defect rate and improving product quality. The automated production process of this device reduces reliance on manual labor and lowers labor costs. At the same time, due to the improvement in product quality and the reduction in the defect rate, it reduces material waste and rework costs caused by defective products, thereby reducing production costs and improving the economic benefits of enterprises.

[0028] Please see Figure 1 One embodiment of this utility model is an automatic single-stripe arrangement device, which includes a working platform 1, a protective shell 5 fixed on the working platform 1, and a PLC controller 6 installed on the protective shell 5.

[0029] Please see Figure 2 The working platform 1 is equipped with a feeding mechanism 2, an arranging mechanism 3, and a positioning mechanism 4. The arranging mechanism 3 is located between the feeding mechanism 2 and the positioning mechanism 4. The PLC controller 6 is electrically connected to the feeding mechanism 2, the arranging mechanism 3, and the positioning mechanism 4 respectively. It receives signals from the sensor 35 and controls the operation of each component according to the preset program. The PLC controller 6 is also used to provide power to the feeding mechanism 2, the arranging mechanism 3, and the positioning mechanism 4. In this embodiment, the PLC controller 6 adopts the OHR-PR10 model.

[0030] Please see Figure 3 The feeding mechanism 2 includes a vibratory feeder 21 and a feeding track 22 disposed on the vibratory feeder 21.

[0031] Please see Figure 4The vibratory feeder 21 is fixed on the working platform 1. A track groove 221 is formed on the feeding track 22. The track groove 221 can limit the two sides of a single watch strap, effectively preventing the single watch strap from shifting during transport. The arrangement mechanism 3 includes a support assembly 31 and a drive assembly 32, an arrangement assembly 33, and a receiving plate 34 disposed on the support assembly 31. The arrangement assembly 33 is located between the drive assembly 32 and the receiving plate 34. The receiving plate 34 is fixed to the upper surface of the working platform 1. A sensor 35 is fixed on the receiving plate 34. In this embodiment, the sensor 35 is a photoelectric sensor. The sensor 35 is located at the end of the feeding track 22 away from the vibratory feeder 21. The support assembly 31 includes a support platform 311, which is fixed to the upper surface of the working platform 1. Two symmetrically arranged supports 312 are fixed on the upper surface of the support platform 311. The drive assembly 32 includes a first motor 321 and a wheel 322 connected to the output end of the first motor 321. The first motor 321 is fixed to the lower surface of the support platform 311. The wheel 322 and the first motor 321 are non-coaxial, and the wheel 322 is located on the support platform. Above 311, the arrangement assembly 33 includes a first slide rail 331 fixed to the upper surface of the support platform 311. A moving block 332 and a push plate 333 located on one side of the moving block 332 are slidably arranged on the first slide rail 331. The moving block 332 is fixedly connected to the push plate 333. An auxiliary wheel 334 is installed at the end of the moving block 332 away from the push plate 333. The auxiliary wheel 334 is in contact with the wheel disk 322. When the first motor 321 drives the wheel disk 322 to rotate, the wheel disk 322 rotates eccentrically, which in turn drives the auxiliary wheel 334 to rotate. At the same time, the auxiliary wheel 334 rotates on the first slide rail 331. Under the action of the moving block 332, it reciprocates horizontally. Two guide rods 335 are provided between the moving block 332 and the push plate 333. The two guide rods 335 are fixed on the two supports 312 respectively. The two ends of the moving block 332 are slidably set on the two guide rods 335 respectively. Therefore, the moving block 332 can slide on the first slide rail 331 and the two guide rods 335 at the same time. Springs 336 are sleeved on the outer side of the two guide rods 335. The two ends of the springs 336 are connected to the supports 312 and the moving block 332 respectively. A pusher strip 337 is fixed at the end of the push plate 333 away from the moving block 332.

[0032] Please see Figure 5 The upper surface of the receiving plate 34 has an input port 341. The sensor 35 is located directly above the input port 341 and is used to detect whether there is a single watch strap in the input port 341. When there is a single watch strap, the PLC controller 6 drives the first motor 321 to run, which drives the pusher bar 337 to push the single watch strap in the input port 341 onto the receiving plate 45. The pusher bar 337 is set horizontally and is located below the sensor 35.

[0033] Please see Figure 6The positioning mechanism 4 includes a fixed base 41 and a second slide rail 42 and a second motor 43 fixed on the fixed base 41. Both the fixed base 41 and the second slide rail 42 are fixed to the upper surface of the working platform 1. The second slide rail 42 and the second motor 43 are distributed at both ends of the fixed base 41. A groove 421 is provided on the upper surface of the second slide rail 42, and a lead screw 44 driven by the second motor 43 is provided on the second slide rail 42. The lead screw 44 is located within the groove 421. The method of the second motor 43 driving the lead screw 44 is existing technology. In this embodiment, a set of synchronous pulleys is connected to the output end of the second motor 43. The synchronous pulleys and... The lead screw 44 is connected, thereby driving the lead screw 44 to rotate. The synchronous pulley can be set inside the fixed base 41. A receiving plate 45 is set on the lead screw 44. The receiving plate 45 is in contact with the end of the receiving plate 34 away from the arrangement assembly 33 and can be translated along the surface of the receiving plate 34 to receive the single watch straps output from the receiving plate 34. The upper end surface of the receiving plate 45 is provided with multiple positioning grooves 451. The multiple positioning grooves 451 are evenly distributed on the receiving plate 45. Each positioning groove 451 can accommodate several single watch straps. The arrangement of multiple positioning grooves 451 makes the single watch straps evenly arranged.

[0034] Working principle: Please refer to the following again. Figures 1 to 6 In operation, the vibratory feeder 21 transports individual watch straps one by one to the feeding track 22. The straps are arranged sequentially through the track groove 221 and transported to the input port 341. When a single watch strap is fed into the input port 341, the sensor 35 detects it and transmits an electrical signal to the PLC controller 6. At this time, the PLC controller 6 drives the first motor 321 to run, causing the wheel 322 to rotate one revolution. The wheel 322 rotates eccentrically, driving the auxiliary wheel 334 to rotate, causing the moving block 332 to translate towards the positioning mechanism 4. This, in turn, drives the push plate 333 to translate towards the positioning mechanism 4, causing the push bar 337 to push the single watch strap in the input port 341 out of the input port. The end of 341 outputs and enters one of the positioning slots 451. After the wheel 322 rotates once, it returns to its original position. The two springs 336 push the moving block 332, the push plate 333 and the auxiliary wheel 334 to slide on the first slide rail 331 and return to their original positions, waiting for the next single watch strap to enter the input port 341, so that the output of single watch straps can be carried out again. When a positioning slot 451 is full of single watch straps, the second motor 43 runs and drives the lead screw 44 to rotate, so that the receiving plate 45 moves a certain distance, so that the next positioning slot 451 is aligned with the end of the input port 341. In this way, the single watch straps can be evenly arranged on the receiving plate 45.

[0035] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
