Description

Technical Field

[0001] This utility model relates to the field of relay assembly equipment technology, and in particular to a relay pusher assembly mechanism. Background Technology

[0002] A relay is an automatic switching element with isolation function, widely used in remote control, telemetry, communication, automatic control, mechatronics, and power electronic equipment, and is one of the most important control components. A relay mainly consists of a coil, iron core, iron frame, hook, armature, push plate, base, housing, and terminals.

[0003] Currently, in the relay manufacturing process, after the coil, iron core, iron frame, and hook are assembled into a coil assembly, the ARM component needs to be inserted between the iron frame and hook of the coil assembly. Then, the coil assembly with the ARM component is assembled on the base, and the pusher is installed on the base. Patent CN113707496B discloses an ARM pusher coil assembly device. In this device, the pusher assembly process involves a robotic arm at the end of the pusher feeding mechanism directly clamping the pusher onto the base. Since the robotic arm only has a single clamping and transfer function, it needs to be pressed by a pusher pressing structure. This method requires multiple devices to work together, resulting in high mechanical investment costs and increased space occupancy on the production line. Utility Model Content

The feeding device includes a feeding vibratory plate with a linear vibration track at its output end. The transfer device is located at the output end of the linear vibration track and has a tooling seat that can move independently horizontally forward and backward and left and right. The tooling seat has transfer jaws, two of which are symmetrically arranged. The top of the adjacent sides of the two transfer jaws has grooves, and the grooves on the two transfer jaws cooperate to form a clamping groove for receiving materials one by one from the output end of the linear vibration track. The transfer device also includes a material control structure located at the output end of the linear vibration track, which can release materials one by one according to a threshold cycle. The feeding device has a feeding end that can move forward and backward, left and right, and up and down. The assembly fixture is located on the feeding end, and a rotary drive is provided between the assembly fixture and the feeding end. The assembly fixture can clamp the pusher located in the clamping groove, move it to the threshold position, and assemble the pusher onto the relay base by means of a flipping action.

[0007] Based on the above technical solution, the top of the output end of the linear vibrating track is provided with a limiting groove, and the material control structure includes a material control lifting seat set on one side of the output end of the linear vibrating track. The material control lifting seat is provided with a vertical material control rod, the top of the material control rod is connected to the material control lifting seat, and the material control lifting seat is connected to a lifting cylinder. After the material control lifting seat moves down, it can drive the bottom of the material control rod to extend into the limiting groove, forming a limiting material control structure at the output end of the linear vibrating track.

[0008] Based on the above technical solution, the transfer device includes a transfer bracket, on which a transfer left and right lateral movement module is provided, and on the movable slider of the transfer left and right lateral movement module is a transfer front and rear lateral movement module, and on the movable slider of the transfer front and rear lateral movement module is connected the tooling base.

[0009] Based on the above technical solution, the feeding direction of the linear vibrating track is the front-to-back direction, the opening and closing direction of the two transfer grippers is the left-to-right direction, the height of the transfer gripping groove is consistent with the height of the output end of the linear vibrating track, and the transfer gripping groove has an open structure on the side near the output end of the linear vibrating track. When the tooling seat moves to the output end of the linear vibrating track, the open end of the transfer gripping groove is aligned and fitted with the output end of the linear vibrating track.

[0010] Based on the above technical solution, the transfer bracket is also equipped with a positioning sensor, and the positioning sensor detects the loading position of the transfer clamping groove located at the output end of the linear vibration track.

[0012] Based on the above technical solution, the assembly fixture is a pneumatic gripper.

[0013] Based on the above technical solution, an angle sensor is provided between the assembly fixture and the movable slider of the feeding left and right transverse module.

[0014] Compared with the prior art, the present invention has at least the following advantages:

[0015] This invention improves upon existing conventional clamping and transfer methods by utilizing the coordinated operation of a feeding device, a transfer device, a feeding device, and an assembly fixture. It employs a rotary drive structure between the assembly fixture and the feeding device, enabling the assembly fixture to clamp the push piece located in the transfer clamping slot, move it to a threshold position, and then, through a flipping motion, snap the push piece onto the relay base. This eliminates the need for a pressing device; in other words, a rotary snap-fit ​​assembly method replaces the traditional pressing assembly method. This simplifies the assembly machinery structure and reduces the space occupied by the structure without affecting assembly quality. Furthermore, the transfer device provides a buffer for feeding, which facilitates stable and smooth feeding. The segmented feeding steps simplify the movement of the assembly fixture, thereby improving processing efficiency. Attached Figure Description

[0025] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0026] Combination Figure 1-4 This embodiment discloses a relay pusher assembly mechanism, including a feeding device 100, a transfer device 200, a feeding device 300, and an assembly fixture 400. The feeding device 100 is used to supply pushers, the transfer device 200 is used to transition the feeding process, and the feeding device 300 cooperates with the assembly fixture 400 to transfer the pushers on the transfer device 200 and assemble them onto the base of the relay. This embodiment aims to optimize the assembly process of the relay pusher, reduce the number of required devices through integrated design, reduce mechanical investment costs, and reduce the space occupancy of the equipment structure.

[0027] The feeding device 100 includes a feeding vibratory plate, and the output end of the feeding vibratory plate is provided with a linear vibration track 110. The feeding vibratory plate and the linear vibration track 110 are used to linearly transport the push plates, which are then led out of the vibratory plate one by one and transported in a certain direction and speed.

[0028] Furthermore, the conveying direction of the linear vibrating track 110 is the front-to-back direction. The top of the output end of the linear vibrating track 110 is provided with a limiting groove 111. The limiting groove 111 is a strip-shaped slot located at the top of the linear vibrating track 110. The length direction of the strip-shaped slot is parallel to the front-to-back direction and is used to cooperate with the limiting structure for material control.

[0029] The transfer device 200 is located at the output end of the linear vibrating track 110. The transfer device 200 is equipped with a tooling base 240 that can move independently horizontally forward and backward, and left and right. The tooling base 240 has two transfer grippers 250 arranged symmetrically on both sides. The top of the adjacent sides of the two transfer grippers 250 has grooves. These grooves together form a clamping groove that can receive materials one by one from the output end of the linear vibrating track 110. The transfer device 200 also includes a material control structure located at the output end of the linear vibrating track 110. The material control structure can release materials one by one according to a threshold cycle. It should be noted that the transfer grippers 250 and the tooling base 240 are detachably connected, allowing for easy replacement of the transfer grippers 250 to meet the operational needs of pushers of different sizes.

[0030] Specifically, in combination Figure 2 and Figure 3 To achieve precise control of the tooling base 240, the transfer device 200 includes a transfer bracket 210, on which a transfer left-right lateral movement module 220 is mounted. A transfer front-back lateral movement module 230 is mounted on the movable slider of the transfer left-right lateral movement module 220, and the tooling base 240 is connected to the movable slider of the transfer front-back lateral movement module 230. Thus, by controlling the movement of the movable sliders of the transfer left-right lateral movement module 220 and the transfer front-back lateral movement module 230, precise control of the tooling base 240 in the horizontal and vertical directions can be achieved, thereby ensuring that the transfer clamping slot 251 can accurately receive the pusher plate output from the linear vibration track 110.

[0031] Furthermore, to optimize the structural design of the transfer clamping groove 251, the feeding direction of the linear vibrating track 110 is front-to-back, and the opening and closing direction of the two transfer grippers 250 is left-to-right. The height of the transfer clamping groove 251 is consistent with the height of the output end of the linear vibrating track 110, and the transfer clamping groove 251 has an open structure on the side near the output end of the linear vibrating track 110. When the tooling base 240 moves to the output end of the linear vibrating track 110, the open end of the transfer clamping groove 251 is aligned and fitted with the output end of the linear vibrating track 110. In this way, when the linear vibrating track 110 outputs a pusher piece, the transfer clamping groove 251 can accurately catch the pusher piece and temporarily store it.

[0032] The material control structure includes a material control lifting seat 260 disposed on one side of the output end of the linear vibrating track 110. A vertical material control rod 261 is mounted on the material control lifting seat 260, with its top connected to the lifting seat 260. A lifting cylinder is connected to the lifting seat 260. When the lifting seat 260 descends, it can drive the bottom of the material control rod 261 into the limiting groove 111, forming a limiting material control structure at the output end of the linear vibrating track 110. The function of the material control structure is to control the rhythm of the pusher plates output by the linear vibrating track 110, ensuring that only one pusher plate is conveyed into the transfer clamping groove 251 at a time, preventing multiple pusher plates from entering simultaneously and causing jamming or damage.

[0033] In order to monitor the loading status of the transfer clamping slot 251 in real time, the transfer bracket 210 is also equipped with a position sensor 270. The detection position of the position sensor 270 is the loading position of the transfer clamping slot 251 located at the output end of the linear vibration track 110. In this embodiment, the position sensor 270 is a through-beam light sensor.

[0034] The feeding device 300 is provided with a feeding end that can move back and forth, left and right, and up and down. The assembly fixture 400 is provided on the feeding end, and a rotary drive 360 ​​is provided between the assembly fixture 400 and the feeding end. The assembly fixture 400 can clamp the push piece located in the transfer clamping groove 251 and move it to the threshold position, and then use the flipping action to fasten and assemble the push piece on the relay base.

[0035] Specifically, to achieve precise control of the feeding end, the feeding device 300 includes a feeding bracket 310, a feeding forward and backward lateral movement module 320 is provided on the feeding bracket 310, a feeding lifting module 330 is provided on the movable slider of the feeding forward and backward lateral movement module 320, a lifting base 340 is provided on the movable slider of the feeding lifting module 330, a feeding left and right lateral movement module 350 is provided on one side of the lifting base 340, a rotary drive 360 ​​is provided on the movable slider of the feeding left and right lateral movement module 350, and the output end of the rotary drive 360 ​​is connected to the assembly fixture 400. In this embodiment, the rotary drive 360 ​​is a servo motor. In order to monitor the flip angle of the assembly fixture 400 in real time, an angle sensor is provided between the assembly fixture 400 and the movable slider of the feeding left and right lateral movement module 350. The angle sensor can monitor the flip angle of the assembly fixture 400 in real time and feed the signal back to the control system. When the flipping angle reaches the set value, the control system can issue a command to stop the flipping operation to ensure that the pusher can be accurately engaged with the relay base.

[0036] To optimize the structural design of the assembly fixture 400, the assembly fixture 400 is a pneumatic gripper. Pneumatic grippers have advantages such as simple structure, convenient operation, and large clamping force, making them suitable for clamping push pieces. Furthermore, the clamping force of the pneumatic gripper can be controlled by adjusting the air pressure to accommodate push pieces of different sizes and shapes.

[0037] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
