Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of intelligent manufacturing equipment, and particularly relates to a posture maintaining output device for an automatic assembly line of a motor starting protector. BACKGROUND

[0002] The motor starting protector is a product obtained by integrating a motor starter and a motor protector in the same housing. There are many technical information related to the motor starting protector in the disclosed Chinese patent documents. Its functions can be fully understood by reading the following patent documents, which are not limited to the examples, such as CN100581043A (Energy-saving integrated single-phase AC motor starting protector) and CN204442206U (Energy-saving single-phase AC motor starting protector).

[0003] As known in the industry, if the motor starting protector is assembled manually, the following technical problems will occur: first, due to the relatively low assembly efficiency, it is difficult to adapt to the speed of automatic assembly of other components such as the structure system of the protector, such as the static contact piece, the dynamic contact piece, and the dynamic insertion piece. Unless sufficient workers are invested, excessive investment in manpower not only wastes valuable labor resources, but also significantly increases overall manufacturing costs. Second, the quality of manual assembly is affected by the experience, proficiency, physical fitness, responsibility, and even mood of the assembly personnel, so the consistency of the assembly quality cannot be guaranteed.

[0004] Automatic assembly can solve the above technical problems. For this purpose, please refer to CN106670803A recommended "Protector automatic assembly device with protector base extraction and release function" and CN113714455A provided "Rivet riveting structure of current starter automatic assembly device", etc.

[0005] As known in the art, although the motor starting protector is not large in size, it contains relatively more components, for example, as for the components of the structural system of the motor protector, there are base, fixed seat, movable contact, static contact, insert piece, bimetallic strip, bimetallic strip supporting ring, top rod (usually ceramic material) and heating wire, etc.; as for the components of the structural system of the motor starter, there are PTC (i.e. positive temperature coefficient thermistor), spring sheet (a pair) and pin (a pair), etc. Therefore, the number of corresponding assembly mechanisms arranged on the workbench in the circumferential direction of the only one rotary disc is limited, because the diameter of the rotary disc is subject to process constraints, for example, if the diameter of the rotary disc is too large, the stability of the rotary disc cannot be guaranteed, and the load of the rotary disc driving mechanism driving the large rotary disc to rotate is also large, on the one hand, it is easy to cause transmission instability, and even frequent failures, because the rotary disc driving mechanism arranged on the workbench is only drivingly connected (usually fixedly connected) with the middle part of the rotary disc, on the other hand, it will produce vibration, affecting the assembly action reliability of the automatic assembly mechanism. Therefore, only a limited number of components can be assembled on the first assembly line, and after the assembly of a limited number of components is completed, the assembly of other components is carried out on the second or next assembly line, and the same is true for the subsequent assembly lines.

[0006] In the automatic assembly process of the motor starting protector, some components such as the bimetallic strip supporting ring and the bimetallic strip mentioned above are assembled on the first assembly line, and since both the bimetallic strip supporting ring and the bimetallic strip are in a state of no positioning constraint, if their posture changes, the previously assembled bimetallic strip supporting ring and / or bimetallic strip will be out of the base (the concept of the base can be referred to CN204442206U), resulting in the previous assembly being in vain. Therefore, after the shell conveying, the bimetallic strip supporting ring assembly and the bimetallic strip assembly on the first assembly line are completed, the posture must be kept unchanged during the whole process of transferring to the next assembly line.

[0007] In view of the above, it is of positive significance to explore an output device that can output the motor starting protector with completed assembly such as the bimetallic strip supporting ring and the bimetallic strip in a state of no positioning constraint without changing the posture (neither tilting nor overturning) during the output process after moving away from the assembly line. The technical solution to be introduced below is generated in this background. SUMMARY

[0022] The aforementioned to-be-assembled shell output mechanism 5 comprises a first supporting pier 51a (like a double-column pier), a second supporting pier 51b (like a double-column pier), a pair of conveying supports 52, a pair of guide plates 53, a driving roller 54a, a driven roller 54b, a conveying belt 55, a driving roller driving motor 56, a driving roller driving motor shaft transmission wheel 57a, a driving roller driving wheel 57b, a driving roller driving wheel transmission belt 58, and a pair of to-be-assembled shell signal collectors 59. The first and second supporting piers 51a and 51b are spaced apart from each other and are each fixed to the aforementioned workbench 1 in the form of a pair; the pair of conveying supports 52 are parallel to each other in the length direction, the middle parts of the pair of conveying supports 52 are respectively fixed to the top of the first supporting pier 51a and the second supporting pier 51b, and a driving roller shaft head rotating support seat 521 is respectively fixed to the right end of the pair of conveying supports 52, and a driven roller shaft head rotating support seat 522 is respectively fixed to the left end of the pair of conveying supports 52; the left end of the pair of guide plates 53 is respectively fixed to the side facing upward of the left end of the pair of conveying supports 52, the middle part is fixed to the side facing upward of the pair of conveying supports 52, and the right end is respectively fixed to the side facing upward of the driving roller shaft head rotating support seat 521; the space between the length direction opposite sides of the pair of guide plates 53 constitutes a to-be-assembled shell moving guide channel 531; the driving roller 54a is rotatingly supported by the driving roller shaft heads 54c at both ends thereof and through bearings between the aforementioned driving roller shaft head rotating support seats 521; the driven roller 54b is rotatingly supported by the driven roller shaft heads at both ends thereof and through bearings between the aforementioned driven roller shaft head rotating support seats 522; one end of the conveying belt 55 is sleeved on the driving roller 54a, and the other end is sleeved on the driven roller 54b; the driving roller driving motor 56 is fixed to a motor fixing seat 561, the driving roller driving motor shaft 562 of the driving roller driving motor 56 extends to the rear of the motor fixing seat 561, the motor fixing seat 561 is fixed to the rear side of the aforementioned first supporting pier 51a and the rear side of the rear one of the pair of conveying supports 52, the driving roller driving motor shaft transmission wheel 57a is fixed to the driving roller driving motor shaft 562, the driving roller driving wheel 57b is fixed to the driving roller shaft head 54c at the rear end of the driving roller 54a, one end of the driving roller driving wheel transmission belt 58 is sleeved on the driving roller driving motor shaft transmission wheel 57a, and the other end is sleeved on the driving roller driving wheel 57b, and the pair of to-be-assembled shell signal collectors 59 are fixed to the middle part of the length direction of the aforementioned pair of conveying supports 52 in the state of corresponding to each other in the front-rear direction.

[0023] In the embodiment, the aforementioned material taking driving motor 63 is a motor with forward and reverse rotation function; the aforementioned material taking lifting cylinder 66 and the material taking clamping cylinder 67 are air cylinders.

[0024] In the embodiment, the aforementioned active roller driving motor 56 is a servo motor or a stepping motor, the aforementioned conveying belt 55 is a belt, the aforementioned active roller driving motor shaft transmission wheel 57a and the active roller driving wheel 57b are synchronous pulleys, and the aforementioned active roller driving wheel transmission belt 58 is a synchronous belt.

[0025] As shown in Figure 1 and Figure 2 A stop bar 523 is fixed between the left ends of the aforementioned pair of supports 52 and at a position corresponding to the left end portions of the aforementioned pair of guide plates 53, and the middle right side of the stop bar 523 corresponds to the aforementioned subsequent shell moving guide channel 531. The subsequent shell moving guide channel 531 blocks the illustrated subsequent shell 4 from the conveying belt 55, preventing it from escaping.

[0026] In the embodiment, the aforementioned material taking transmission screw connecting plate first displacement stroke signal collector 68 and the material taking transmission screw connecting plate second displacement stroke signal collector 69 are micro switches, but they can also be stroke switches or position proximity switches; and the aforementioned pair of subsequent shell signal collectors 59 are reflective photoelectric sensors.

[0027] The applicant describes the working process of the subsequent assembly shell lifting and transferring mechanism 6. The material taking driving motor 63 works to drive the material taking transmission screw rod 64, which drives the screw rod moving nut block 642, which drives the material taking moving screw rod connecting plate 65. When the material taking moving screw rod connecting plate 65 moves to the extent that the signal can be collected by the material taking transmission screw rod connecting plate second displacement stroke signal collector 69, the signal is fed back to the electrical controller by the material taking transmission screw rod connecting plate second displacement stroke signal collector 69, and the electrical controller sends a temporary stop working instruction to the material taking driving motor 63. At this time, the material taking lifting action cylinder 66 fixed on the material taking moving screw rod connecting plate 65 and the pair of material taking clamping jaws 672 of the material taking clamping action cylinder 67 connected with the material taking lifting action cylinder up and down sliding plate 661 through the material taking clamping action cylinder seat 671 are just above the shell carrying mold 3. In the above state, the material taking lifting action cylinder up and down sliding plate 661 moves downward together with the material taking clamping action cylinder 67 by the work of the material taking lifting action cylinder 66, and the pair of material taking clamping jaws 672 clamps the subsequent assembly shell 4 on the shell carrying mold 3 by the work of the material taking clamping action cylinder 67. Then the material taking clamping action cylinder 67 moves upward together with the subsequent assembly shell 4 clamped by the pair of material taking clamping jaws 672 by the reverse work of the aforementioned material taking lifting action cylinder 66. After reaching the set delay time, the aforementioned material taking driving motor 63 works in reverse, and the aforementioned opposite movement process is followed until the material taking moving screw rod connecting plate 65 moves to the extent that the signal can be collected by the material taking transmission screw rod connecting plate first displacement stroke signal collector 68. The material taking driving motor 63 stops working again. For the same reason as mentioned above, the subsequent assembly shell 4 in the clamped state corresponds to the upper part of the subsequent assembly shell moving guide channel 531 of the structure system of the subsequent assembly shell output mechanism 5, and is released to the subsequent assembly shell moving guide channel 531, i.e. to the conveyor belt 55, by the material taking clamping action cylinder 67 descending and being repelled by the pair of material taking clamping jaws 672. The material taking driving motor 63 works again to make the material taking clamping action cylinder 67 return to the upper part corresponding to the shell carrying mold 3 again. This is repeated to extract and release the subsequent assembly shell 4 to the conveyor belt 55 corresponding to the aforementioned subsequent assembly shell moving guide channel 531.

[0028] The applicant describes the working process of the subsequent assembly shell output mechanism 5. When a pair of subsequent assembly shell signal collectors 59, which are photoelectric sensors, collect the subsequent assembly shell 4 on the subsequent assembly shell moving guide channel 531, the signal is fed back to the electrical controller by the pair of subsequent assembly shell signal collectors 59. The electrical controller gives instructions to the driving motor 56, which drives the driving motor shaft 562, which drives the driving motor shaft transmission wheel 57a, which drives the driving motor wheel transmission belt 58, which drives the driving motor wheel 57b, which drives the driving roller 54a, which drives the conveyor belt 55. The subsequent assembly shell 4 moves towards the driven roller 54b and is blocked by the blocking strip 523 on the pair of conveyor supports 52. The subsequent assembly shell 4 at the blocking strip 523 is extracted and transferred to the subsequent assembly line by the mechanical hand. Whenever a pair of subsequent assembly shell signal collectors 59 detects a subsequent assembly shell 4, a signal is fed back to the electrical controller, and the driving motor 56 works once. The working time is set by the PLC.

[0029] The above-mentioned subsequent assembly shell output mechanism 5 and the subsequent assembly shell lifting and transferring mechanism 6 can ensure that the posture of the subsequent assembly shell 4, which has completed the assembly of the bimetallic strip support ring and the bimetallic strip, does not change. Specifically, it can also be guaranteed by the subsequent assembly shell moving guide channel 531. Although the assembly of the bimetallic strip support ring and the bimetallic strip has been completed, these two components are not yet in a state of positioning constraint. Once the posture changes, such as tilting, falling, or even turning over, the bimetallic strip support ring and the bimetallic strip will be out of place, resulting in a waste of effort. Therefore, the present application can fully guarantee that the subsequent assembly shell 4 is conveyed to the position of the blocking strip 523 without changing the posture, and is extracted by the mechanical hand in the state of being blocked by the blocking strip 523 and is transferred one by one to the adjacent next assembly line to realize the assembly of other components, which embodies the posture keeping between assembly lines.

[0030] In summary, the technical solution provided by the present application makes up for the shortcomings in the prior art and successfully completes the invention task, and faithfully realizes the technical effects described by the applicant in the above technical effect column.
