Description

Technical Field

[0001] This invention relates to the field of industrial safety interlocking devices, and more particularly to a safety interlocking actuator. Background Technology

[0002] In the field of industrial safety today, numerous safety interlocking devices are emerging. The mainstream approach uses key insertion to drive a cam rotation, thereby controlling the operation of the safety interlocking device. However, industrial environments are complex, and purely mechanical keys are easily blocked, posing safety risks. This invention, a safety interlocking actuator (TBL1-K1), uses RFID signal triggering to avoid signal blocking and effectively improve the level of safety protection. Based on traditional safety keys, this safety interlocking actuator (TBL1-K1) allows for more flexible adjustment of the triggering direction. The induction antenna can rotate once every 90°, providing four triggering directions. Furthermore, the overall installation of this safety interlocking actuator (TBL1-K1) provides two installation directions, effectively enhancing its practicality. Because this safety interlocking actuator (TBL1-K1) incorporates elastic components, it effectively solves the problem of the traditional safety interlocking device's key being affected by the rotation radius of the safety door, thus improving its applicability and suitability for more complex environmental conditions. Summary of the Invention

[0003] The purpose of this invention is to provide a safety interlock actuator to solve the above-mentioned technical problems.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A safety interlock actuator includes an actuator body and mounting components, which are integrated and fixed to a mounting surface by screws. The actuator body comprises a pin, an antenna, and an antenna cover. The mounting components consist of a rear cover screw, an actuator front housing, a pin base, a pin anti-tamper screw, a spring, and an actuator rear cover. The antenna is installed in the mounting hole of the pin and secured by the antenna cover. Resin glue is injected into the round hole on the back of the pin to secure the pin, antenna, and mounting surface. The three components—the antenna cover, the actuator body, and the actuator pin base—are bonded together to form the actuator body. The pin base is installed inside the actuator front housing, with its shaft passing through the hole in the actuator front housing from the inside out. The antenna cover of the actuator body faces the sensing area of ​​the safety interlock device. The actuator body is inserted into the pin base from front to back, and the actuator body and pin base are fixed with the pin anti-tamper screws. The spring is installed in the groove on the back of the pin base, and the actuator rear cover is used to press the spring and press it into the actuator front housing. The actuator rear cover and actuator front housing are fixed with two rear cover screws.

[0006] Compared with existing technologies, the present invention has the following advantages: The safety interlock actuator (TBL1-K1) of the present invention is made of metal, which can provide a larger locking force, solving the problem of insufficient locking force of the key in safety interlock actuators; the present invention uses a simple anti-tamper screw connection, allowing authorized personnel to easily adjust the relative direction of the present invention and the safety interlock in industrial sites, thereby adapting to changes in the triggering direction caused by on-site installation of the safety interlock device, and preventing unauthorized personnel from arbitrarily adjusting or maliciously blocking the triggering safety signal; the present invention uses a flexible triggering component, which can solve the problem of the safety interlock device being affected by the rotation radius of the safety door, making it suitable for more small industrial safety scenarios and more working conditions; the present invention has a small size and multiple adjustable triggering angles, making it widely applicable in complex industrial environments; the present invention uses RFID signal triggering to detect the operation of the moving mechanism, providing high safety redundancy and low risk of malicious blocking.

[0012] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0013] like Figure 1-4 As shown, a safety interlock actuator includes an actuator body 1 and a mounting component 2. The actuator body 1 and the mounting component 2 are used as a whole and are fixed to the mounting surface 12 by mounting screws 13.

[0014] The actuator body 1 consists of a pin 3, an antenna 4, and an antenna cover 5; the mounting component 2 consists of a rear cover screw 6, an actuator front shell 7, a pin base 8, a pin anti-tamper screw 9, a spring 10, and an actuator rear cover 11; the antenna 4 is installed in the mounting hole of the pin 3, and is also secured in the mounting hole of the pin 3 by the antenna cover 5; resin glue is poured into the round hole on the back of the pin 3 to bond the pin 3, the antenna 4, and the antenna cover 5 together to form the actuator body 1; the pin base 8 is installed in the actuator... Inside the front housing 7 of the actuator, the shaft of the pin base 8 passes through the hole of the front housing 7 of the actuator from the inside to the outside. The antenna cover 5 of the actuator body 1 faces the sensing area of ​​the safety interlock device. The actuator body 1 is inserted into the pin base 8 from front to back, and the actuator body 1 and the pin base 8 are fixed with the pin anti-tamper screw 9. The spring 10 is installed in the groove on the back of the pin base 8. The actuator rear cover 11 is used to press the spring 10 and press it into the actuator front housing 7. The actuator rear cover 11 and the actuator front housing 7 are fixed by two rear cover screws 6.

[0015] Assembly process: First, install the antenna 4 into the mounting hole of the pin 3, then install the antenna cover 5 into the mounting hole of the pin 3. After assembling the pin 3, antenna 4, and antenna cover 5, turn the assembly over and pour resin glue into the round hole on the back of the pin 3 to bond the pin 3, antenna 4, and antenna cover 5 together. This not only provides waterproofing and dustproofing but also prevents vibration. The assembly of the pin 3, antenna 4, and antenna cover 5 constitutes the actuator body 1 of this invention. Then, install the pin base 8 into the actuator front housing 7, so that the shaft of the pin base 8 rotates from the inside towards the outside. Insert the actuator through the hole in the front housing 7 of the actuator, then adjust the assembled actuator body 1 to the required direction of the sensing antenna, ensuring that the antenna cover 5 faces the sensing area of ​​the safety interlock device when finally used. Insert the actuator 1 into the pin base 8 from front to back, and fix the actuator body 1 and the pin base 8 with the pin anti-tamper screw 9. Then, install the spring 10 into the groove on the back of the pin base 8, press the spring 10 with the actuator rear cover, and press it into the actuator front housing 7. Fix the actuator rear cover 11 and the actuator front housing with two rear cover screws 6.

[0016] When used in industrial settings, the direction of the actuator body 1 can be adjusted to ensure that the antenna cover 5 always faces the sensing area of ​​the safety interlock device. The specific adjustment method is as follows: First, unscrew all the rear cover screws 6, remove the spring 10 and the actuator rear cover 11, and then unscrew the anti-tamper screw 9. At this time, the actuator body 1 and the mounting part 2 have been separated. Pull out the actuator body 1 and rotate it once every 90°, for a total of 4 rotations. When the actuator body 1 is rotated to the required position, insert the actuator 1 into the pin base 8 and fix the actuator body 1 and the pin base 8 with the anti-tamper screw 9. Then, install the spring 10 into the groove on the back of the pin base 8, press the spring 10 with the actuator rear cover 11, press it into the actuator front shell 7, and fix the actuator rear cover 11 and the actuator front shell 7 with the two rear cover screws 6.

[0017] In use, this invention can adjust the relative orientation of the actuator body 1 and the mounting part 2 separately, and can also adjust the positional relationship between the invention and the mounting surface 12 as a whole. It only requires removing the mounting screws 13 that fix the invention and the mounting surface 12, adjusting the invention to the required position, and then fixing the invention and the mounting surface 12 with the mounting screws 13.

[0018] When used in industrial settings, the direction of the actuator body 1 can be adjusted to ensure that the antenna cover 5 always faces the sensing area of ​​the safety interlock device. The specific adjustment method is as follows: First, unscrew all the rear cover screws 6, remove the spring 10 and the actuator rear cover 11, and then unscrew the anti-tamper screw 9. At this time, the actuator body 1 and the mounting part 2 have been separated. Pull out the actuator 1 and rotate it once every 90°, for a total of 4 rotations. When the actuator 1 is rotated to the required position, insert the actuator body 1 into the pin base 8 and fix the actuator body 1 and the pin base 8 with the anti-tamper screw 9. Then, install the spring 10 into the groove on the back of the pin base 8, press the spring 10 with the actuator rear cover 11, press it into the actuator front shell 7, and fix the actuator rear cover 11 and the actuator front shell 7 with the two rear cover screws 6.

[0019] In use, this invention can adjust the relative orientation of the actuator body 1 and the mounting part 2 separately, and can also adjust the positional relationship between the invention and the mounting surface 12 as a whole. It only requires removing the mounting screws 13 that fix the invention and the mounting surface 12, adjusting the invention to the required position, and then fixing the invention and the mounting surface 12 with the mounting screws 13.

[0020] In this invention, the actuator body 1 and the mounting part 2, as well as the mounting surface 12, can be easily adjusted and reliably fixed for use.

[0021] The anti-tamper screw in this invention features an anti-tamper design, requiring specialized tools for removal to prevent malicious disassembly and the shielding of safety signals. Similarly, the mounting screw 13 used to install this invention also employs an anti-tamper design, requiring specialized tools to remove it from the mounting surface 12 to prevent malicious disassembly and the shielding of safety signals.

[0022] When this invention comes into contact with the safety interlocking device, it has flexible properties. When the installation of this invention deviates significantly from the safety interlocking device, it can avoid damage to the device caused by hard contact. In this invention, the spring 10 can adjust the position of the actuator body 1 and the safety interlocking device when the invention receives hard contact, thereby achieving the effect of energy absorption and effectively preventing the device from being damaged. It is also suitable for safety doors with smaller rotation radii.

[0023] The above description represents a preferred embodiment of the present invention. For those skilled in the art, any changes, modifications, substitutions, and variations made to the implementation methods without departing from the principles and spirit of the present invention, based on the teachings of the present invention, still fall within the protection scope of the present invention.
