Description

Technical Field

[0001] The utility model relates to the technical field of switches, and particularly relates to a switch pin inserting device. Background Art

[0002] A switch refers to an electronic component that can open a circuit, interrupt the current, or cause the current to flow to other circuits. Common switches include micro switches, rocker switches, toggle switches, slide switches, push-button switches, key switches, etc. A switch generally has multiple components, and during the production and processing process, multiple components need to be assembled into a whole product. A common switch generally has metal pins (also called leads, terminals) provided on a base to facilitate the conduction connection between the switch and other electrical components. The number of pins varies according to different switch design requirements, but most are two or more. During the production process of the switch, first, the metal pins need to be inserted into the holes preset on the switch base to fix the metal pins on the base, and then the remaining components of the switch are installed. In traditional operations, the pin inserting operation is generally carried out by a pin inserting device. The operator places the base of the switch at the pin inserting device, and the pin inserting device then inserts the pins into the base. After the insertion is completed, the base is taken out and transferred to another pin inserting device for the insertion operation of other pins. In the case of a switch with a large number of pins, this method requires multiple material loading and unloading and transfers. The socket operation process has poor continuity, is cumbersome to operate, and has low efficiency. Content of the Utility Model

Detailed Embodiment

[0024] To facilitate the understanding of the utility model by those skilled in the art, the following will further describe the utility model in detail in combination with specific embodiments and drawings.

[0025] Referring to Figures 1 to 5, the present utility model provides a switch pin insertion device, which includes a chassis 1, a working platform 11 arranged on the chassis 1, a conveying mechanism 2 arranged on the working platform 11, a base feeding mechanism 3 arranged on the chassis 1, a plurality of pin insertion mechanisms arranged on the working platform 11, a pin foot feeding mechanism arranged on the base, and a hot riveting mechanism 6 arranged on the working platform. The plurality of pin insertion mechanisms are arranged in sequence along the conveying direction of the conveying mechanism 2, and the hot riveting mechanism 6 is close to the end of the conveying mechanism 2. The conveying mechanism 2 is used to sequentially convey the switch base between the plurality of pin insertion mechanisms and between the hot riveting mechanisms 6. Thus, after the switch base completes the pin insertion operation of one of the pin feet, it is quickly transferred to the next working station, and the operation continuity is strong. The switch base is fed into the conveying mechanism 2 by the base feeding mechanism 3. The conveying mechanism 2 conveys the base to move, and after sequentially completing the pin insertion operations of different pin feet, it leaves the conveying mechanism 2 after being riveted by the hot riveting structure.

[0026] The pin insertion mechanism includes a guide block 41 arranged on the working platform 11, a lifting frame 42 connected to the guide block 41, a pressing component 43 connected to the lifting frame 42, and a pin insertion driving part 44 arranged in the chassis 1. The pin insertion driving part 44 is connected to the lifting frame 42. The lifting frame 42 specifically includes two guide shafts and connecting blocks connected to both ends of the guide shafts. The pressing component 43 is connected to the connecting block at the upper end. When the pin insertion driving part 44 drives the lifting frame 42 to move in the vertical direction, the pressing component 43 moves accordingly. In this embodiment, the pin insertion driving part 44 adopts a cylinder.

[0027] The pressing component 43 includes a fixed block 431 connected to the lifting frame 42, a pin insertion seat 432 connected to the fixed block 431, and a pin insertion head 433 connected to the pin insertion seat 432. The pin insertion head 433 matches the switch base and the corresponding pin foot.

[0028] In this embodiment, three pin insertion mechanisms are provided, including a first pin insertion mechanism 45, a second pin insertion mechanism 46, and a third pin insertion mechanism 47 arranged in sequence along the conveying direction of the conveying mechanism 2. Three pin foot feeding mechanisms are provided, including a first pin foot feeding mechanism 53, a second pin foot feeding mechanism 54, and a third pin foot feeding mechanism 55 corresponding to the first pin insertion mechanism 45, the second pin insertion mechanism 46, and the third pin insertion mechanism 47 respectively. Of course, when the switch to be processed has more terminals, the corresponding number of pin insertion mechanisms can be set according to the number of terminals.

[0029] The hot riveting mechanism 6 includes a riveting support 61, a lifting seat 62 connected to the riveting support 61, a hot riveting block 63 connected to the lifting seat 62, a riveting head 64 connected to the bottom of the hot riveting block 63, and a hot riveting driving member 65 for driving the lifting seat 62 to move; the riveting head 64 is located above the conveying mechanism 2. In this embodiment, the hot riveting driving member 65 uses a cylinder, and the shape of the riveting head 64 matches the model of the switch base. After all the pins are inserted, the switch base reaches the corresponding position of the hot riveting mechanism 6, and the riveting head 64 presses down for the final riveting.

[0030] The conveying mechanism 2 includes a conveying seat 21 arranged on the working platform 11, a horizontal driving assembly 22 arranged at the bottom of the working platform 11, a vertical driving assembly 23 connected to the horizontal driving assembly 22, and a plurality of push rods 24 connected to the vertical driving assembly 23. A slit is arranged at the position of the conveying seat 21 corresponding to the conveying channel, and the push rods 24 extend through the slit to the conveying channel. Specifically, in this embodiment, the slit divides the conveying seat 21 into two parts, namely a first seat body and a second seat body. One side of the top surface of the first seat body close to the second seat body is recessed downward to form a first channel, and the second seat body is provided with a corresponding second channel. The first channel and the second channel form the conveying channel, and the push rods 24 enter the conveying channel from the slit to facilitate the movement of the switch base.

[0031] The horizontal driving assembly 22 specifically includes a horizontal moving plate and a horizontal cylinder for driving the horizontal moving plate. The vertical driving assembly 23 specifically includes a vertical moving plate connected to the horizontal moving plate and a vertical cylinder for driving the vertical moving plate to move up and down. With the cooperation of the horizontal driving assembly 22 and the vertical driving assembly 23, the push rods 24 can rise to the height corresponding to the switch base, then push the switch to move a set distance, and finally the push rods 24 descend and reset to the initial position. By repeating this action, the switch base is conveyed at the same rhythm, and the switch base moves the same distance each time. In addition, a plurality of spring pressing blocks can be arranged on the conveying seat 21, and the distance between adjacent spring pressing blocks is equal to the distance that the switch base moves each time, so that the switch base can be tightly pressed and positioned after each movement.

[0032] The conveying mechanism 2 is provided with a feeding assembly 7 matching the pin feeding mechanism. The number of the feeding assemblies 7 corresponds to the number of the pin inserting mechanisms. The feeding assembly 7 includes a feeding seat 71 arranged on the conveying mechanism 2, a material blocking seat 72 arranged on the conveying mechanism 2, and a material blocking block movably connected to the material blocking seat 72. When the pressing assembly 43 moves down, the material blocking block moves away from the conveying channel. The material blocking block is inserted into the material blocking seat 72, the material blocking block can move in the horizontal direction (the moving direction is perpendicular to the conveying direction of the conveying mechanism 2), and a spring is connected between the material blocking block and the material blocking seat 72. As shown in the appendixFigure 3 As shown (to avoid obscuring the stop block, the leftmost pin is hidden), specifically, the stop block supports the pin from below the pin. An inclined surface or arc surface is formed between the top surface and the side surface of the stop block. When the inserting needle head 433 is pressed down, the stop block moves away from the conveying path. At this time, there is no support below the pin. As the inserting needle head 433 continues to be pressed down, the pin is pressed into the corresponding position of the switch base. When the inserting needle head 433 resets, the stop block resets under the action of the spring and supports the next pin. In addition, if the structure of the pin causes the inserting needle head 433 to be unable to contact and cooperate with the stop block, a push rod that cooperates with the stop block can be additionally provided. The push rod can be connected to the fixing block 431 of the pressing component 43. For example, in the first pin inserting mechanism 45 of this embodiment, a push rod is provided on the fixing block 431. The push rod moves down with the fixing block 431 and inserts into the stop seat 72 to contact the stop block and push the stop block to move.

[0033] The feeding seat 71 of the feeding component 7 is provided with a feeding path 74. The shape of the feeding path 74 matches the shape of the corresponding terminal, so that after the terminal enters the feeding path 74, it can flow stably and orderly above the conveying path.

[0034] The pin feeding mechanism includes a vibrating disk 51 provided on the chassis 1, a feeding path 52 connected to the vibrating disk 51. The feeding path 52 extends above the conveying mechanism 2 and is connected to the corresponding feeding component 7. In addition, in this embodiment, the structure of the base feeding mechanism 3 and the pin feeding mechanism is similar. The difference is that the base feeding mechanism 3 further includes a temporary storage feeding path provided at the starting end of the conveying mechanism 2 to ensure that the switch bases can be fed into the conveying path one by one.

[0035] A calibration component 8 is connected to the pressing component 43 of the first pin inserting mechanism 45. The calibration component 8 includes a calibration seat 81 connected to the pressing component 43 and a calibration piece 82 connected to the calibration seat 81.

[0036] A controller 12 is provided on the chassis 1. The controller 12 can adjust the processing parameters and control each processing mechanism.

[0037] During specific operation, the base feeding mechanism 3 provides switch bases to the conveying mechanism 2. The pusher rod 24 of the conveying mechanism 2 sends the switch bases into the conveying path one by one under the cooperation of the horizontal driving component 22 and the vertical driving component 23. The switch bases pass through the first pin inserting mechanism 45, the second pin inserting mechanism 46, and the third pin inserting mechanism 47 in sequence, and perform different pin inserting operations in sequence. Finally, they reach the hot riveting mechanism 6. After being riveted by the hot riveting mechanism 6, the pin inserting operation is completed. Finally, the switch bases are sent out of the conveying path. Specifically, a conveying mechanism can be set to be connected to the conveying path to facilitate sending the switch bases with pins inserted to the next process.

[0038] The utility model is provided with a plurality of pin insertion mechanisms. With the cooperation of the conveying mechanism 2, the base feeding mechanism 3 and the pin feeding mechanism, the switch base passes through each pin insertion mechanism in sequence, realizing the pin insertion operation of different pins. The processing has strong continuity, without repeated transfer, improving the production efficiency. On the other hand, the utility model realizes automation from feeding, conveying to pin insertion, without manual intervention, further improving the production efficiency.

[0039] During the working process of the utility model, it can cooperate with the pin insertion device. The number of pins of different switches is different, and different pins need to be sequentially inserted into the switch base in sequence. For example, when the processed base has three pins, three pin insertion devices need to be set, that is, corresponding to three pin insertion operation stations. The utility model conveys the switch base orderly between multiple pin insertion operation stations, so as to facilitate each pin insertion device to insert the pins into the switch base.

[0040] The utility model is provided with a conveying channel and a driving mechanism. The driving mechanism can push the switch base to move along the conveying channel, moving the same set distance each time, accurately and orderly sending the switch base into each pin insertion station, realizing continuous pin insertion operation, without repeated and cumbersome material collection and transfer, shortening the processing time and improving the production efficiency.
