Detailed Implementation

[0025] The present invention will be further described in detail below with reference to the accompanying drawings.

[0026] This embodiment discloses a thermostat terminal mounting device, such as... Figures 2-7 As shown, the system includes a machine base 1, on which are mounted a terminal feeding mechanism 2 for conveying terminals 12, a terminal transfer mechanism 3 for moving terminals to the thermostat body 11, and a screw mounting mechanism 4 for fixing terminals to the thermostat body 11. The terminal feeding mechanism 2 uses a vibratory feeder to continuously feed terminals through the feeding channel. The terminal transfer mechanism 3 includes a chuck 301 that is opened and closed by a finger-clamping cylinder. The chuck 301 can clamp terminals and then move in conjunction with a mature cylinder-slider mechanism. Specifically, it moves back and forth between the feeding position of the terminal feeding mechanism 2 and the mounting position of the screw mounting mechanism 4, continuously moving the delivered terminals to the mounting position for installation. The terminal transfer mechanism 3 has at least two types of movement: horizontal and vertical. The general process is as follows: the chuck 301 first opens, then moves vertically downwards towards the terminal at the feeding position of the terminal feeding mechanism 2. Next, the chuck 301 clamps the terminal, then rises and moves the terminal horizontally to the required installation position of the screw mounting mechanism 4. Finally, it descends and places the terminal against the temperature controller body, waiting for the screw mounting mechanism 4 to install the screw. After the screw is installed, the chuck 301 is released, moves back to the feeding position, and repeats the above process.

[0027] Furthermore, the screw installation mechanism 4 in this embodiment includes a first lifting platform 41 and a second lifting platform 42. The first lifting platform 41 is provided with a screw clamp 5, and the second lifting platform 42 is provided with a screwdriver 6 and a motor 61 that drives it to rotate. The screw clamp 5 is provided with a vertical channel 51 and an oblique channel 52. The vertical channel 51 is for the screwdriver 6 to extend into, and the oblique channel 52 is for the screw to enter. A pair of limiting clamps 7 are provided at the bottom end of the vertical channel 51. The limiting clamps 7 are driven by a finger-clamping cylinder to clamp and release. After the pair of limiting clamps 7 clamp, they limit the screw head. When the screwdriver screws the screw into the thermostat body, the limiting clamps 7 release the limitation on the screw head. With the above structure, screw 13 first enters from the inclined channel 52, then falls to the limiting clamp 7. Then the second lifting platform 42 descends, driving screwdriver 6 downward along the vertical channel 51, so that the screwdriver tip and the screw head of screw 13 come into contact. Then the first lifting platform 41 and the second lifting platform 42 descend synchronously, allowing screw 13 to pass through the terminal and abut against the mounting hole of the thermostat body. Motor 61 drives screwdriver 6 to rotate, screwing screw 13 into the thermostat body 11 and fixing and pressing the terminal 12, thus completing the installation. During the process, the limiting clamp 7 can automatically release the limiting of the screw head.

[0028] Further, the structure of the limiting clip 7 for limiting and automatically releasing the limitation comprises a pair of matched clip body a 71 and clip body b 72, the clip body a 71 and the clip body b 72 are clamped to form a through hole 73 in the shape of an inverted cone. The head of the screw is just matched with the through hole 73, and the clamping of the clip body a 71 and the clip body b 72 realizes the limitation of the screw. The limiting clip 7 is provided with a transverse groove 70, the clip body a 71 and the clip body b 72 are arranged in the transverse groove 70 and can move relatively with respect to the transverse groove 70. When the screw is screwed into the main body of the temperature controller, the downward force of the screw is affected by the tapered through hole 73, generating a horizontal and outward pushing force, and the clip body a 71 and the clip body b 72 can slide to both sides along the transverse groove, thereby automatically avoiding the rotation and downward pressing of the screw. Through the above structure, the clip body a and the clip body b do not need to be loosened in advance, but are automatically avoided in the process of screwing in. Referring to Figure 6 Since the structures of the clip body a and the clip body b are the same, the clip body a is taken as an example in the figure. When the screw is screwed down, the clip body a will be pushed away to both sides in the direction of the dotted arrow, so that the screw is always limited and clamped in the process of screwing in, which is more stable. Even in the case of long-time processing, mechanical vibration and the like, the screw can remain in the state of being screwed in vertically. When the screw is installed, the limiting clip 7 can be actively loosened by the clip finger connected thereto, moved away from the screw and then clamped to prepare for the installation of the next screw.

[0029] Further, the transverse groove 70 is provided with a trapezoidal slide rail 8 inside, the clip body a and the clip body b are provided with a trapezoidal slide 9, and the trapezoidal slide rail 8 is matched with the trapezoidal slide 9. Through the above structure, the sliding of the clip body a and the clip body b in the transverse groove 70 is realized.

[0030] Further, referring to Figure 6 , in order to prevent the clip body a and the clip body b from coming out, one end of the transverse groove 70 is closed, and the other end is provided with a limiting screw 701, and the structures of the clip body a and the clip body b at the limiting screw 701 are the same, Figure 6 Taking the clip body a as an example, during installation, the limiting screw 701 is not screwed on first, the clip body a is installed in the transverse groove 70 from the side of the limiting screw 701, and then the limiting screw 701 is screwed on. The limiting screw 701 can prevent the clip body a from coming out of the transverse groove.

[0031] Further, referring to Figure 7 , the clip body a 71 is provided with a magnetic attraction part 711, and the clip body b 72 is provided with an attraction part 721 which is attracted to the magnetic attraction part 711. Through the attraction of the magnetic attraction part 711 and the attraction part 721, the combination of the clip body a and the clip body b is more accurate and stable, and the through hole 73 formed is not easy to be out of position.

[0032] Further, the temperature controller terminal mounting device further comprises a screw feeding mechanism by air blowing, the specific structure of the screw feeding mechanism by air blowing is same as the prior art (for example, the feeder of the blowing and sucking integrated locking adaptive screw machine in CN221910672U), the feeding air pipe in the prior art is connected with the inclined channel 52, and the screw is blown into the inclined channel 52.

[0033] The embodiment further discloses a temperature controller assembling machine 10, referring to Figure 1 which comprises one or more temperature controller terminal mounting devices as described above. The temperature controller assembling machine comprises a temperature controller main body feeding mechanism, a temperature sensing piece mounting mechanism, and a temperature controller main body discharging mechanism after assembly, in simple terms, the temperature controller assembling machine firstly installs the temperature sensing piece in the mold seat, then feeds the temperature controller main body, installs the temperature controller main body in the mold seat and above the temperature sensing piece, then installs the terminal and screw on the temperature controller main body through the temperature controller terminal mounting device, fixes the terminal, the temperature controller main body and the temperature sensing piece together through the screw, and finally discharges through the discharging mechanism.

[0034] The above only describes the preferred embodiment of the utility model, and is not used for limiting the utility model, any modification, equivalent replacement, improvement and the like within the design concept of the utility model should be contained in the protection scope of the utility model.
