Description

Technical Field

[0001] The invention relates to the technical field of thermal relay assembly, in particular to thermal relay assembly equipment. Background Art

[0002] As an overload protection element, thermal relays are widely used in production due to their small size, simple structure, and low cost. The thermal element of a thermal relay is an element that generates heat through current, causing the bimetallic strip to deform. When current passes through the thermal element, the heat generated causes the bimetallic strip to deform due to different expansion coefficients. When the deformation reaches a certain distance, it pushes the connecting rod to disconnect the control circuit, thereby achieving overload protection for the motor.

[0003] The main structure of the thermal element includes a bimetallic strip, a resistance wire, a metal rod and a conductive plate. One end of the bimetallic strip is fixed to the conductive plate, and the other end of the bimetallic strip is connected to the connecting rod. The resistance wire is wound around the bimetallic strip, and one end of the metal rod is connected to the resistance wire, while the other end and the conductive plate are connected to the terminals of the thermal relay. The working principle of the thermal relay is that the current flowing into the thermal element generates heat, causing the bimetallic strip with different expansion coefficients to deform. When the deformation reaches a certain distance, it pushes the connecting rod to disconnect the control circuit, thereby causing the contactor to lose power, disconnecting the main circuit, and achieving overload protection.

[0004] During the assembly process of thermal relays, the manufacturing accuracy of thermal elements plays a vital role in the performance of thermal relays.

However, manual assembly has the problems of low thermal element assembly efficiency and poor assembly consistency of multiple thermal elements on one carrier.

In this embodiment, the three feeding jaws 222 clamp the three thermal elements 100 in a row or a column on the tray mechanism 1 one by one along the first direction X or along the second direction Y, and then the first sliding member 23 drives the base 221 to move, thereby driving the three feeding jaws 222 to move to the transfer area. Specifically, the feeding clamp 222 is a clamp cylinder.

[0070] Optionally, the grab assembly 22 further includes a first driving unit 223, which drives the base 221 to rotate around the rotation axis in the vertical direction Z, and the first sliding member 23 is configured to drive the first driving unit 223 to move along the first direction X or the second direction Y or the vertical direction Z; the first direction X and the second direction Y are located in a horizontal plane. In this embodiment, when the three feeding jaws 222 clamp the thermal element 100 along the first direction X, the first driving unit 223 is required to drive the base 221 to turn 90°, so that the three feeding jaws 222 located in the transfer area are arranged along the second direction Y. Specifically, the first driving unit 223 is a rotary cylinder.

[0071] Optionally, the first sliding member 23 includes a first sliding portion 231, a second sliding portion 232 and a third sliding portion 233. The first sliding portion 231 is arranged on the first bracket 21.

[0072] Optionally, the feeding jaw 222 includes a first feeding jaw 222a, a second feeding jaw 222b and a third feeding jaw 222c in order of arrangement, the first feeding jaw 222a is fixedly connected to the base 221, the second feeding jaw 222b and the third feeding jaw 222c are respectively slidably matched with the base 221; the grasping assembly 22 also includes an adjusting member, the adjusting member includes a cylinder 224, a connecting rod 225 and a driving pin 226, one end of the connecting rod 225 is fixedly connected to the second feeding jaw 222b, and the other end of the connecting rod 225 is provided with a first waist-shaped hole 2251 along the sliding direction of the third feeding jaw 222c, the driving pin 226 passes through the first waist-shaped hole 2251 and is fixedly arranged on the third feeding jaw 222c, and the cylinder 224 drives the second feeding jaw 222b or the third feeding jaw 222c to slide relative to the base 221. In this embodiment, since the distance between two adjacent thermal elements 100 on the tray mechanism 1 is smaller than the minimum distance between two adjacent transfer jaws 32 on the transfer mechanism 3, when the loading jaw 222 clamps the thermal element 100 on the tray mechanism 1, the distance between two adjacent loading jaws 222 is smaller than the distance between two adjacent loading jaws 222 located in the transfer area. To achieve this function, the cylinder 224 drives the third loading jaw 222c to move toward the first loading jaw 222a. When the driving pin 226 in the first waist-shaped hole 2251 abuts against one end of the first waist-shaped hole 2251 close to the first loading jaw 222a, the distance between the second loading jaw 222b and the third loading jaw 222c is at its minimum. The spacing is fixed with each other, and the cylinder 224 continues to drive the third loading jaw 222c to move. At this time, the second loading jaw 222b and the third loading jaw 222c synchronously approach the first loading jaw 222a until the spacing between the first loading jaw 222a and the second loading jaw 222b is equal to the spacing between the third loading jaw 222c and the second loading jaw 222b. At this time, the cylinder 224 stops working, and the spacing between the first loading jaw 222a and the second loading jaw 222b and the spacing between the third loading jaw 222c and the second loading jaw 222b are equal to the spacing between two adjacent thermal elements 100 on the tray mechanism 1. Therefore, the three loading jaws 222 can clamp three adjacent thermal elements 100 on the tray at the same time.

[0073] When the three feeding jaws 222 are located in the transfer area, the cylinder 224 drives the third feeding jaw 222c to move in the direction away from the first feeding jaw 222a. When the driving pin 226 in the first waist-shaped hole 2251 abuts against the end of the first waist-shaped hole 2251 away from the first feeding jaw 222a, the distance between the second feeding jaw 222b and the third feeding jaw 222c is at the maximum distance and fixed to each other. The cylinder 224 continues to drive the third feeding jaw 222c to move. At this time, the second feeding jaw 222b and the third feeding jaw 222c synchronously move to the third feeding jaw 222c. The loading jaw 222a moves away until the distance between the first loading jaw 222a and the second loading jaw 222b is equal to the distance between the third loading jaw 222c and the second loading jaw 222b. At this time, the cylinder 224 stops working, and the distance between the first loading jaw 222a and the second loading jaw 222b and the distance between the third loading jaw 222c and the second loading jaw 222b are equal to the minimum distance between two adjacent loading jaws 32 on the loading mechanism 3. Therefore, the three loading jaws 32 can clamp the thermal elements 100 on the three loading jaws 222 at the same time.

In this embodiment, since the rotating jaw 32 needs to be rotated 90° so that the assembly jaw 423 can clamp the third conductive plate 103 in the clamping area, but the conductive rod 104 is softly connected to the resistance wire 105, when the rotating jaw 32 rotates, it is easy to destroy the shape and position of the conductive rod 104. Therefore, the first clamping part 3231 is required to clamp the second conductive plate 102, and the second clamping part 3232 is required to clamp the conductive rod 104.

In this embodiment, the auxiliary pressing block 4232 abuts against the first conductive plate 101 while the auxiliary pressing block 4232 abuts against the bimetallic strip 106. When the second sliding member 422 drives the third clamping portion 4231 to move along the vertical direction Z in the direction of the mounting slot 431 of the carrier 43, in order to prevent the third conductive plate 103 from sliding relative to the third clamping portion 4231 along the vertical direction Z, and the first conductive plate 101 from deforming relative to the third conductive plate 103, the auxiliary pressing block 4232 abuts against the first conductive plate 101, and the first conductive plate 101 is pressed into the mounting slot 431 through the auxiliary pressing plate 3212.

After the thermal elements 100 are assembled in the multiple mounting grooves 431 of the carrier 43, the lifter restores the carrier 43 to the first position, and at this time, the conveyor belt 411 transports the carrier 43 fully assembled with the thermal elements 100 away from the assembly component 42.
