[0029] Different from manually taking the temperature limiter 1, the present application sets a vibration component, which drives the temperature limiter 1 to move through vibration to realize automatic feeding, and further limits and transports the temperature limiter 1 through the guide rail component, so that the temperature limiter 1 is arranged neatly, and the material distribution unit at the end of the guide rail component takes the orderly transported temperature limiter 1 for material distribution. The above structure can realize automatic feeding of the temperature limiter 1, replacing the manual operation of taking the temperature limiter 1, and at the same time solves the problem of material jamming caused by the temperature limiter 1 when distributing materials, thereby releasing labor, reducing employee labor intensity, improving feeding efficiency, enhancing product competitiveness, and improving the degree of automation of the production line. The present application can be combined with other automation mechanisms to realize automatic assembly of the temperature limiter 1, and provide an automatic feeding solution for the automatic assembly of the temperature limiter 1.

[0030] In the temperature limiter feeding mechanism of this embodiment, the vibration assembly includes a vibration disk 2 and a transition guide rail 3. The transition guide rail 3 connects the discharge end of the vibration disk 2 and the guide rail assembly. After the temperature limiter 1 in the vibration disk 2 is limited by vibration, it moves from the discharge end to the transition guide rail 3 for transportation.

[0031] Specifically, the vibration plate 2 is designed according to the appearance, size, weight and material of the temperature limiter 1 to ensure that the temperature limiter 1 automatically arranges the material for discharge along the spiral rise of the vibration plate 2. The working principle of the vibration plate 2 in this application is the prior art and will not be described in detail here.

[0032] In the temperature limiter feeding mechanism of this embodiment, the guide rail assembly includes a guide rail base 4 and a guide rail baffle 5, two guide rail baffles 5 are provided and are relatively arranged above the guide rail base 4, and a material guide channel is formed between the guide rail base 4 and the guide rail baffle 5, and the material guide channel is connected to the discharge end of the transition guide rail 3 to connect the limited temperature limiter 1.

[0033] Specifically, a guide rail assembly is provided to increase the distance between the transition guide rail 3 and the material distribution unit, thereby increasing the number of temperature limiters 1 that can be carried and improving the conveying and loading efficiency; the two guide rail baffles 5 and the guide rail base 4 below form a groove-shaped material guiding channel, and the guide rail baffles 5 limit the temperature limiter 1 transported on the guide rail base 4 in the left and right directions to prevent the temperature limiter 1 from tilting or even falling on the guide rail base 4.

[0034] In the temperature limiter feeding mechanism of this embodiment, a straight vibrator 7 is installed below the guide rail base 4, a guide groove is provided between the guide rail baffle 5 and the guide rail base 4, the temperature limiter fixing ear 17 is embedded in the guide groove, the height of the guide groove is adjustable, the guide rail baffle 5 is parallel to the temperature limiter plug terminal 6, and a gap is left between the two.

[0035] Specifically, the guide rail base 4 is arranged along the extension direction of the transition guide rail 3, and the straight vibrator 7 drives the guide rail base 4 to vibrate and connect with the transition guide rail 3 to realize that the temperature limiter 1 vibrates and automatically arranges the material forward along the guide rail assembly. In this application, the thickness of the temperature limiter fixing ear 17 is relatively thin, about 0.4mm, and the fixing ear is easily deformed and stuck, and the temperature limiter 1 discharge guide rail needs to be designed with an adjustable structure.

[0036] Preferably, the guide rail baffle 5 is connected to the guide rail base 4 by screws and is designed as an adjustable spacing structure. The screws are adjusted so that the spacing of the guide grooves between the guide rail baffle 5 and the guide rail base 4 is adjusted to the thickness of the temperature limiter fixing ear 17, thereby avoiding stacking of materials when the temperature limiter 1 is arranged for discharging; the guide rail baffle 5 is set to be parallel to the temperature limiter plug terminal 6 and a small gap is designed to further limit the temperature limiter 1, so that the temperature limiter 1 is transported in a direction parallel to the temperature limiter plug terminal 6, thereby avoiding the temperature limiter 1 from rotating and getting stuck when the temperature limiter 1 is arranged for discharging, and at the same time improving the neatness of the discharging, which is convenient for subsequent material division operations.

[0037] In the temperature limiter feeding mechanism of this embodiment, the dispensing unit includes a receiving component, and the receiving component includes a temperature limiter seat 8. The temperature limiter seat 8 is located at the discharge end of the guide rail assembly and matches the shape of the temperature limiter 1.

[0038] Specifically, the temperature limiter 1 is limited when discharging materials on the guide rail assembly, and the direction of the temperature limiter fixing ear 17 is parallel to the extension direction of the material guide channel. The temperature limiter seat 8 is located at the end of the guide rail assembly, that is, perpendicular to the material guide channel. Therefore, a limiting groove matching the shape of the temperature limiter fixing ear 17 is provided on the temperature limiter seat 8, thereby facilitating the clamping of the temperature limiter 1 to receive the temperature limiter 1.

[0039] In the temperature limiter feeding mechanism of this embodiment, the material distribution unit also includes a grabbing component and a driving component. The grabbing component is arranged at the output end of the driving component. The driving component drives the grabbing component to grab the temperature limiter 1 on the temperature limiter seat 8 and drive it to move.

[0040] Specifically, the grabbing assembly includes a clamp 9, which is installed at the output end of the pneumatic finger 10 in the driving assembly. The pneumatic finger 10 drives the clamp 9 to move to grab or release the temperature limiter 1. The pneumatic finger 10 is set at the output end of the telescopic cylinder 11. The telescopic cylinder 11 drives the pneumatic finger 10 and the temperature limiter 1 to move in the horizontal direction. The telescopic cylinder 11 is set at the output end of the lifting cylinder 12. The lifting cylinder 12 is extended and drives the telescopic cylinder 11, the pneumatic finger 10 and the temperature limiter 1 to move in the vertical direction, thereby driving the temperature limiter 1 to the specified position.

[0041] Preferably, the material of the temperature limiter shell is divided into bakelite and ceramic. There is a difference in friction when the temperature limiter 1 is clamped, and a suitable material of the clamping jaw 9 needs to be selected; the clamping jaw 9 is designed to imitate the cylindrical surface of the temperature limiter 1 shell, and stainless steel is used for machine processing to ensure the processing accuracy, so as to achieve stable clamping of the temperature limiter 1 with ceramic and bakelite shell materials.

[0042] The temperature limiter feeding mechanism of this embodiment also includes a slide cylinder 13, a positioning plate is arranged above the slide cylinder 13, and the material distribution unit is fixed on the positioning plate. The slide cylinder 13 is extended and retracted to drive the positioning plate and the material distribution unit above it to move axially along the slide cylinder 13 to move away from or close to the guide rail assembly.

[0043] Specifically, the slide cylinder 13 drives all parts on the positioning plate to move axially. During the reciprocating motion of the slide cylinder 13, the lifting cylinder 12 does not move. At this time, the lifting cylinder 12 remains in a retracted state to press the temperature limiter 1; the lifting cylinder 12 will only move when the slide cylinder 13 is stationary, that is, when it is extended or retracted into place.

[0044] Specifically, after the temperature limiter 1 moves from the guide rail assembly to the temperature limiter seat 8 and is in place, the clamp 9 presses the temperature limiter 1, and then the slide cylinder 13 drives the entire material distribution unit to move, and the temperature limiter 1 leaves the guide rail assembly, realizing automatic material distribution of the temperature limiter 1, and at the same time realizing separate material distribution to avoid overlapping and jamming.

[0045] In the temperature limiter feeding mechanism of this embodiment, a blocking assembly is provided at the discharge end of the guide rail assembly, and the blocking assembly includes a blocking cylinder 14 and an optical fiber sensor 15 connected to the signal of the blocking cylinder 14, and the optical fiber sensor 15 is arranged on the temperature limiter seat 8. The blocking cylinder 14 is arranged perpendicular to the guide rail assembly and its output end extends into the material guiding channel.

[0046] Specifically, a blocking cylinder 14 is added to the discharge port of the straight vibration guide rail, i.e., the guide rail assembly, and an optical fiber sensor 15 is installed on the temperature limiter seat 8. When the previous temperature limiter 1 enters the temperature limiter seat 8 and is recognized as in place by the optical fiber sensor 15, the output end of the blocking cylinder 14 is extended and inserted into the material guide channel to block the next temperature limiter 1 to avoid overlapping and jamming of materials. The optical fiber sensor 15 is used to identify whether the temperature limiter fixing ear 17 is blocked, so as to automatically determine whether the temperature limiter 1 is in place, and realize automatic material sorting and clamping when the temperature limiter 1 is in place.

[0047] In the temperature limiter feeding mechanism of the present embodiment, the discharge end of the transition guide rail 3 and the discharge end of the guide channel are respectively provided with an air blowing pipe 16, and the air blowing pipe 16 is arranged above the limited temperature limiter 1. The air blowing pipe 16 blows air to the limited temperature limiter 1 during the conveying process, so that the limited temperature limiter 1 is distributed at intervals.

[0048] Specifically, blowing pipes 16 are respectively installed at the discharge positions of the vibration plate 2 and the straight vibration guide rail, i.e., the guide rail assembly, for blowing. The blowing function of the blowing pipe 16 is increased so that the temperature limiter 1 is dispersed from each other when it vibrates and moves forward, further avoiding the overlapping of the temperature limiter fixing ears 17 to cause material jamming.

[0049] Specifically, the working process of the temperature limiter feeding mechanism in the present application includes: pouring the temperature limiter 1 into the vibration plate 2, turning on the vibration plate 2 and the straight vibrator 7 and the air blowing pipe 16, the temperature limiter 1 vibrates and feeds in the vibration plate 2, and is transported along the transition guide rail 3 and the guide rail assembly. After the temperature limiter 1 reaches the temperature limiter seat 8, the output end of the blocking cylinder 14 extends to block the subsequent temperature limiter 1, and at the same time, the lifting cylinder 12 contracts to drive the clamping claw 9 to approach the temperature limiter 1, and the pneumatic finger 10 drives the clamping claw 9 to tighten and clamp the temperature limiter 1, and then the slide cylinder 13 extends The retraction drives the temperature limiter seat 8 to move to separate the temperature limiter 1 from the guide rail assembly, the lifting cylinder 12 extends to drive the clamping jaws 9 and the temperature limiter 1 to leave the temperature limiter seat 8, the telescopic cylinder 11 extends to drive the clamping jaws 9 and the temperature limiter 1 to reach the placement position, and the clamping jaws 9 are released to complete the loading. At this time, the telescopic cylinder 11 contracts and the slide cylinder 13 resets to drive the temperature limiter seat 8 back to the end of the guide rail assembly to prepare to receive the next temperature limiter 1, and the blocking cylinder 14 is retracted to release the temperature limiter 1. Wait for the next temperature limiter 1 to reach the temperature limiter seat 8 and repeat the above steps.

[0050] The present application also proposes an assembly production line, including the temperature limiter feeding mechanism, which includes the beneficial effects of the temperature limiter feeding mechanism in the above-mentioned embodiments.
