Description

Technical Field

[0001] This utility model relates to the field of automation equipment technology, specifically to a rubber band gripping and detection device, and in particular to a device for detecting the gripping status during the rubber band feeding process. Background Technology

[0002] In automated rubber band assembly processes, a vibratory feeder is typically used to feed the rubber bands, and a clamp transfers them from the vibratory feeder outlet to the expander for further processing. In existing technology, the clamp picks up the rubber band at the vibratory feeder outlet and then moves directly to the expander station. However, due to the instability of the vibratory feeder's feeding or deviations in the clamp's gripping action, the clamp often fails to pick up the rubber band, resulting in it running unloaded to the expander station. This unloaded phenomenon not only reduces production efficiency but also increases the equipment's ineffective running time, affecting the overall production cycle time.

[0003] Currently, there is a lack of real-time detection methods for the gripping status of fixtures. Operators often need to deal with no-load issues through periodic inspections or after-the-fact detection, which not only increases the frequency of manual intervention but also makes it difficult to achieve full automation of the production process. Therefore, there is an urgent need for a device that can detect in real time whether the fixture has successfully gripped the rubber band during the rubber band feeding process, in order to effectively reduce the number of no-load incidents and improve gripping efficiency. Utility Model Content

[0004] This invention addresses the aforementioned problems by installing sensors along the feeding path. These sensors are specifically designed to identify whether the gripper is holding the rubber band during the process of gripping the rubber band and transferring it to the expander. This enables real-time monitoring of the gripping status and effectively solves the problem of low efficiency caused by no-load conditions in the prior art.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a rubber band gripping and detection device, including a frame, a vibratory feeder for feeding rubber bands and an expander for spreading rubber bands are respectively arranged on both sides of the frame, a clamp is arranged on the frame through a drive mechanism 4, the clamp moves to the outlet of the rubber band on the vibratory feeder as a first working position, the clamp moves to the expansion rod of the expander as a second working position, a rubber band conveying path is formed between the first working position and the second working position, and a sensor is arranged on the frame facing the conveying path, the sensor is used to identify whether the clamp is gripping the rubber band.

[0006] The aforementioned rubber band gripping and detection device has a third working position where the clamp pauses during its movement along the conveying path, and the sensor identifies whether the clamp is gripping the rubber band at the third working position.

[0007] The aforementioned rubber band gripping and detection device includes a drive mechanism 4 that rotates around the frame, with the clamp arranged on one side of the swing arm and swinging accordingly.

[0008] In the aforementioned rubber band gripping and detection device, a motor is installed at the rotation position of the swing arm and the frame to drive the swing arm to rotate relative to the frame to the first working position, the third working position, and the second working position.

[0009] In the aforementioned rubber band gripping and detection device, a first cylinder connected to a swing arm is arranged on the upper part of the frame. The first cylinder is used to push the swing arm to swing between a first working position and a third working position.

[0010] In the aforementioned rubber band gripping and detection device, a slider connected to a first cylinder is arranged on the upper part of the frame. The slider can convert its linear motion into the swing motion of the swing arm via the first cylinder.

[0011] In the aforementioned rubber band gripping and detection device, a second cylinder connected to a slider is arranged on the upper part of the frame. The second cylinder can drive the slider to slide along the surface of the frame.

[0012] The beneficial effects of this utility model are: through the above technical solution, it is possible to detect in real time whether the fixture has successfully gripped the rubber band, effectively avoiding the problems of low equipment efficiency and production cycle delay caused by no-load operation, and improving the reliability and automation level of the gripping process.

[0018] Reference Figure 1-3The rubber band gripping and detection device includes a frame 1. A vibratory feeder 2 for feeding rubber bands is installed on one side of the frame 1, and an expander 3 for spreading rubber bands is installed on the other side. The expander 3 has an expandable expansion rod 31. A drive mechanism 4 is installed on the frame 1. The drive mechanism 4 is connected to and drives a clamp 9, so that the clamp 9 can move between the rubber band outlet of the vibratory feeder 2 (the first working position) and the expansion rod 31 of the expander 3 (the second working position), thereby forming a rubber band conveying path. The key feature is that a sensor 10 is installed on the frame 1 along the rubber band conveying path, facing the path, to identify in real time whether the clamp 9 has successfully gripped the rubber band. The function of this sensor 10 is to solve the problem of not being able to detect the gripping status of the clamp in real time, thereby effectively identifying the no-load situation, avoiding the ineffective operation of the equipment, and thus improving production efficiency and automation.

[0019] One of the core components of this solution is the drive mechanism 4 that drives the movement of the clamp 9. Specifically, two parallel technical solutions are provided to drive the swing arm 5 to swing.

[0020] Option 1: The drive mechanism 4 includes a swing arm 5 rotatably connected to the frame 1 via a rotating shaft. A motor is installed at this rotating position, and the output shaft of the motor is connected to the rotating shaft of the swing arm 5, which can directly drive the swing arm 5 to rotate relative to the frame 1. The clamp 9 is arranged at one end of the swing arm 5 and swings synchronously with it. By controlling the rotation angle of the motor, the clamp 9 can be precisely driven to the first working position, the third working position (if sometimes), and the second working position. The scheme of directly driving the swing arm 5 with a motor has the function of achieving high-precision point control, smooth motion trajectory, and compact structure, which helps to improve the positioning accuracy and operational stability of the entire device.

[0021] Option 2: The drive mechanism 4 can also adopt a pneumatic scheme. A second cylinder 8 is installed on the upper part of the frame 1. The piston rod of the second cylinder 8 is connected to a slider 7. The slider 7 is slidably engaged with the guide rail 11 set on the upper surface of the frame 1, so that the second cylinder 8 can drive the slider 7 to make linear reciprocating motion along the guide rail 11. The tail of the cylinder body of the first cylinder 6 is hinged to the slider 7, and the end of its piston rod is hinged to the swing arm 5. When the second cylinder 8 pushes the slider 7 to move linearly, it will drive the cylinder body of the first cylinder 6 to move, thereby forcing the piston rod of the first cylinder 6 to push and pull the swing arm 5, and finally converting the linear motion of the slider 7 into the swing motion of the swing arm 5. The function of this pneumatic drive assembly is to provide another reliable drive method. By using the cooperation of the cylinder and the slider, linear motion is converted into swing motion. The cost is relatively low and the response speed is fast, which is suitable for automation scenarios that require fast cycle time.

[0022] During the movement of the fixture 9 from the first working position to the second working position, it can pause at a preset third working position. During this brief pause, the sensors 10 arranged on the frame 1, such as photoelectric sensors or fiber optic sensors, will detect the gripper area of ​​the fixture 9 to determine whether it has successfully gripped the rubber band. The third working position is set and mid-process detection is performed. Its function is to provide an optimal detection time. At this time, the fixture has moved away from the interference area of ​​the vibratory feeder and has not yet reached the expansion station. The detection results are more reliable. Once no load is detected, measures can be taken immediately to further optimize the production cycle.

[0023] Operating Procedure: First, the drive mechanism 4 (such as a motor or a combination of first and second cylinders) moves the swing arm and clamp to the first working position above the vibratory feeder outlet. The clamp performs a gripping action, grabbing the rubber band. After gripping, the drive mechanism 4 moves the clamp along a preset path towards the expander. When it passes or reaches the third working position, the mechanism will pause briefly. If a rubber band is detected at this time: the control system receives the "material present" signal from the sensor and instructs the drive mechanism 4 to continue moving, smoothly delivering the clamp to the expansion rod of the expander (second working position). The clamp releases, and the rubber band is placed on the expansion rod, completing the loading. If no rubber band is detected (no load): the control system receives the "no material present" signal from the sensor, determines that the gripping has failed, and can immediately and automatically execute the preset re-gripping program to try to grip again. Regardless of whether the loading is successful or not, after one action is completed, the swing arm and clamp return to the initial position under the command of the control system, ready to start the next work cycle.
