Description

Technical Field

[0001] This application relates to the field of flexible printed circuit board manufacturing technology, and more specifically, to a gravity pin height limiting device for SMT cover. Background Technology

[0002] Traditionally, height limiters are used to control the height of SMT cover weight pins before they enter the oven. If the SMT cover weight pins are not pressed down or are not pressed down to the correct position, they will be blocked by the height limiters, thus controlling the cover height. However, this can easily damage the SMT cover and the product.

[0003] Therefore, this application proposes an SMT capping gravity PIN height limiting device to solve the aforementioned problems. Utility Model Content

[0004] To address the aforementioned issues, this application provides an SMT capping gravity PIN height limiting device.

[0005] The SMT capping gravity PIN height limiting device provided in this application adopts the following technical solution:

[0006] SMT capping gravity PIN height limiting device, including base,

[0007] The top of the base is provided with a plurality of aluminum profiles arranged longitudinally and evenly, and the aluminum profiles are connected by a transverse circular shaft; a conveyor belt and an induction optical fiber are respectively provided on the opposite surface and top of adjacent aluminum profiles; a height limiting carrier is placed on the conveyor belt.

[0008] The pressure cap body has several pins on it; the bottom of the pressure cap body is provided with a pressure cap positioning device, and the height limiting carrier is provided with positioning holes that correspond to and match the pressure cap positioning device.

[0009] Furthermore, the pressure cap positioning includes a column and a cone disposed at the bottom of the column, the diameter of the column is larger than the diameter of the positioning hole, and the maximum diameter of the column is the same as the diameter of the positioning hole.

[0010] The above technical solution enables the cap body to be accurately and stably positioned when installed on the height-limiting vehicle. This positioning method not only ensures the accuracy of the contact position between the cap gravity PIN and the product, guaranteeing the normal functioning of the cap, but also effectively reduces the risks caused by shaking and displacement during the transportation and operation of the cap, improving the reliability and stability of the entire device and thus improving the processing quality of the product.

[0011] Furthermore, the top and outer side of the outermost aluminum profile are respectively provided with a three-color light and a reset button that are connected to the sensing fiber optic electronic control.

[0012] Through the above technical solution, a complete abnormal alarm and handling mechanism has been formed. When the sensing fiber detects an abnormal height of the pressure cap PIN, the three-color light quickly sounds an alarm, alerting staff with a bright light and a buzzer, enabling timely detection of the abnormality. The reset button allows staff to quickly clear the alarm and restore the equipment to normal operation after the abnormality is resolved, significantly shortening the abnormality handling time, reducing equipment downtime, and improving production efficiency and management convenience.

[0013] Furthermore, it also includes a blocking cylinder electrically connected to the sensing fiber optic cable. The blocking cylinder is vertically disposed between adjacent aluminum profiles and located at the end of the moving direction of the height limiting vehicle. In the initial state, the height limiting vehicle is located in front of the adjacent sensing fiber optic cable, and the blocking cylinder is located behind the adjacent sensing fiber optic cable.

[0014] Through the above technical solution, the blocking cylinder connected to the sensing fiber optic electronic control is set at the end of the moving direction of the height-limiting vehicle. When an abnormal height is detected, it can quickly extend to block and prevent the abnormal cover from entering the subsequent processing stage. This design effectively avoids the damage of the unqualified cover to other equipment or products, protects the safety of production equipment and products, and also prevents a series of production problems caused by the abnormal cover flowing into the subsequent process, ensuring the continuity and stability of the entire production process.

[0015] Furthermore, a blocking wheel is rotatably mounted on the top of the piston rod of the blocking cylinder. In the initial state, the highest point of the blocking wheel is at the same height as the bottom of the height-limiting vehicle; the upper dead point of the stroke of the piston rod driving the blocking wheel up and down is equal to or greater than the highest point of the height-limiting vehicle.

[0016] The above technical solution effectively reduces wear on the height restriction vehicle while ensuring the blocking effect. The blocking wheel makes rotational contact with the height restriction vehicle, which greatly reduces friction compared to rigid blocking, extends the service life of the height restriction vehicle, and reduces equipment maintenance costs. Moreover, its adjustable lifting stroke can flexibly adapt to height restriction vehicles of different heights, ensuring reliable blocking function under various conditions, further improving the practicality and reliability of the device.

[0017] Furthermore, the main body of the pressure cover is also symmetrically provided with buckles that engage with the height-limiting vehicle.

[0018] Through the above technical solution, the buckle can effectively prevent the cap body from loosening or shifting during the cap transportation process. Even in the event of vibration or bumps, it can ensure that the cap body is always in the correct position, ensuring the accurate correspondence between the cap gravity PIN and the product, providing a more reliable guarantee for product quality. At the same time, it reduces the readjustment and correction work caused by cap shifting, and improves production efficiency.

[0019] In summary, this application includes at least one of the following beneficial technical effects:

[0020] (1) This application achieves accurate detection, timely alarm and effective blocking of cap height through the coordinated cooperation of multiple structures. Compared with the traditional method, it can significantly reduce the risk of product damage caused by abnormal cap height, greatly improve the product qualification rate and production quality, reduce scrap rate and production cost, and at the same time ensure the safe operation of production equipment and improve the stability and reliability of production.

[0028] Example:

[0029] The following is in conjunction with the appendix Figure 1 -3 provides further detailed description of this application.

[0030] This application discloses an SMT cover pressure PIN height limiting device, including a base.

[0031] The top of the base is provided with a plurality of aluminum profiles arranged longitudinally and evenly, and the aluminum profiles are connected by a transverse circular shaft; a conveyor belt and an induction optical fiber are respectively provided on the opposite surface and top of adjacent aluminum profiles; a height limiting carrier is placed on the conveyor belt.

[0032] The pressure cap body has several pins on it; the bottom of the pressure cap body is provided with a pressure cap positioning device, and the height limiting carrier is provided with positioning holes that correspond to and match the pressure cap positioning device.

[0033] See Figure 1 , Figure 2 Figure 3 The cap positioning system includes a column and a cone at the bottom of the column. The diameter of the column is larger than the diameter of the positioning hole, and the maximum diameter of the column is the same as the diameter of the positioning hole. This allows the cap body to be accurately and stably positioned when installed on the height-limiting vehicle. This positioning method not only ensures the accuracy of the contact position between the cap gravity PIN and the product, guaranteeing the normal functioning of the cap, but also effectively reduces the risks caused by shaking and displacement during cap transportation and operation, improving the reliability and stability of the entire device and thus improving the processing quality of the product.

[0034] See Figure 1 , Figure 2 Figure 3 The outermost aluminum profile has a tri-color light and a reset button connected to the sensing fiber optic control on its top and outer sides, respectively. This forms a complete alarm and handling mechanism. When the sensing fiber optic detects an abnormal height of the pressure cap PIN, the tri-color light quickly sounds an alarm, alerting staff with a bright light and a buzzer, ensuring timely detection of the abnormality. The reset button allows staff to quickly deactivate the alarm and restore the equipment to normal operation after the abnormality is resolved, significantly shortening the handling time, reducing equipment downtime, and improving production efficiency and management convenience.

[0035] See Figure 1 , Figure 2 Figure 3 The system also includes a blocking cylinder electrically connected to the sensing fiber optic cable. The blocking cylinder is vertically positioned between adjacent aluminum profiles and at the end of the height-limiting carrier's movement direction. In the initial state, the height-limiting carrier is located in front of the adjacent sensing fiber optic cable, and the blocking cylinder is located behind the adjacent sensing fiber optic cable. The blocking cylinder, electrically connected to the sensing fiber optic cable, is located at the end of the height-limiting carrier's movement direction. When an abnormal height is detected, it can quickly extend to block the abnormal cap from entering subsequent processing stages. This design effectively avoids damage to other equipment or products caused by caps with unqualified heights, protecting the safety of production equipment and products. It also prevents a series of production problems caused by abnormal caps flowing into subsequent processes, ensuring the continuity and stability of the entire production process.

[0036] See Figure 1 , Figure 2 Figure 3 The piston rod of the blocking cylinder is rotatably equipped with a blocking wheel. In the initial state, the highest point of the blocking wheel is at the same height as the bottom of the height-limiting vehicle. The upper dead point of the piston rod driving the blocking wheel to move up and down is equal to or greater than the highest point of the height-limiting vehicle. While ensuring the blocking effect, it effectively reduces wear on the height-limiting vehicle. When the blocking wheel contacts the height-limiting vehicle, it is a rotational contact, which greatly reduces friction compared to rigid blocking, extends the service life of the height-limiting vehicle, and reduces equipment maintenance costs. Moreover, its adjustable lifting stroke can flexibly adapt to height-limiting vehicles of different heights, ensuring reliable blocking function under various conditions, further improving the practicality and reliability of the device.

[0037] See Figure 1 , Figure 2 Figure 3The cap body is also symmetrically provided with buckles that engage with the height-limiting carrier. During the transportation of the cap, the buckles can effectively prevent the cap body from loosening or shifting. Even in the event of vibration or bumps, the cap body can be kept in the correct position, ensuring the accurate correspondence between the cap gravity PIN and the product. This provides a more reliable guarantee for product quality and also reduces the readjustment and correction work caused by cap shifting, thus improving production efficiency.

[0038] The implementation principle of the SMT capping gravity PIN height limiting device in this application embodiment is as follows: When the SMT capping gravity PIN height limiting device is running, the aluminum profile, round shaft and conveyor belt 4 at the top of the base form a conveying channel. The capping body 7 at the bottom of the capping body cooperates with the positioning hole on the height limiting carrier to achieve initial positioning. At the same time, the buckle on the capping body engages with the height limiting carrier to further fix the capping body and ensure its stability during the conveying process. Then the height limiting carrier carries the capping body to move on the conveyor belt 4.

[0039] When the height restriction carrier passes the sensing fiber optic cable on top of the adjacent aluminum profile, the sensing fiber optic cable detects the height of the gravity pin on the cap body. If the gravity pin height is normal, the height restriction carrier continues to move along the conveyor belt 4. Once an abnormal height is detected, the sensing fiber optic cable immediately transmits a signal to the three-color light and the blocking cylinder connected to it. The three-color light then lights up and sounds a buzzer alarm to alert the staff to the abnormal situation. At the same time, the blocking cylinder located at the end of the height restriction carrier's moving direction is activated, and the piston rod drives the top blocking wheel to rise, blocking the height restriction carrier from continuing to move forward and preventing the cap with abnormal height from entering the subsequent process.

[0040] After handling the abnormal situation, the staff pressed the reset button on the outermost aluminum profile, the three-color alarm was deactivated, the piston rod of the blocking cylinder drove the blocking wheel to descend, the height limit vehicle resumed movement, and continued to enter the subsequent processing process.

[0041] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
