Description

Automatic heating and pressurizing leveling device for electric heating wire of protector

Technical Field

The utility model belongs to the technical field of the special facility of electron electrical product automated production assembly line, concretely relates to heating wire self-heating pressurization leveling device of protector.

Background

The structure of the refrigeration compressor motor protector can be referred to as an overload protector of a single-phase alternating current motor recommended by the invention patent publication No. CN100356652C, and the refrigeration compressor motor protector with the structure is reasonably combined with a refrigeration compressor motor starter to form a 'refrigeration compressor motor starting and protecting device', such as CN2606490Y (a motor starting protector), CN2606491Y (an integrated motor starting and protecting device), CN102386815B (an integrated motor starting protector with improved structure) and CN100581043C (an energy-saving integrated single-phase alternating current motor starting and protecting device), and the like. Typically, the patent document CN204425126U provides an energy-saving integrated single-phase ac motor protection device, which includes the structure of CN 100356652C.

It is clear from a reading of the specifications cited above, in particular CN100356652C and CN204425126U, and not limited thereto, in particular the specifications 0039 to 0045 of the "energy-saving single-phase alternating current motor starting protector" proposed by the invention patent application publication No. CN104734569A, and a reading of fig. 4 in conjunction with this CN 104734569A: the motor protector of the refrigeration compressor mainly comprises a base, a fixed seat, a movable contact piece (also called movable pin), a static contact piece (also called static pin), an inserting piece (also called pin), a bimetallic strip, a mandril and an electric heating wire, wherein the base is also called the fixed seat and correspondingly called the fixed seat as the base. The movable contact piece, the fixed contact piece and the insert piece are all arranged by taking a base as a carrier (the base is called as a "fixed base" by CN 100356652C), that is, the above components are all arranged on the base.

As described in paragraph 0045 of the above-mentioned CN104734569A, when the bimetal is subjected to the radiation heat of the heating wire or the external environment, the bimetal will deform, and the deformation is expressed as: the peripheral edge part is turned downwards, and the central part is arched upwards, so that the central part of the bimetallic strip is arched to push the top rod to move upwards, the moving and static contacts of the two pins in the closed state are separated, and the circuit is opened to protect the motor of the compressor.

The better the whole contact effect of the electric heating wire of the structural system of the motor protector of the refrigeration compressor and the bimetallic strip is, the better the deformation effect of the bimetallic strip is correspondingly, and the higher the reliability of the break circuit is. However, since the heating wire is manually accommodated in a heating wire accommodating chamber (also referred to as an "accommodating chamber") which is preset at a side of the base facing the bimetal, and since the heating wire is similar in structure to the spring, there occurs a difference in flatness of the heating wire installed in the heating wire accommodating chamber due to factors such as experience, responsibility, and emotion of an assembly worker, and the difference results in: it is difficult or even impossible to ensure the full contact of the heating wire with the bimetal. Yet another situation is: during initial assembly, even if the heating wire is not fully embedded in the heating wire accommodating cavity, the contact state between the heating wire and the bimetallic strip can be basically expected in the industry, but along with the time lapse, repeated expansion and contraction change, the whole contact effect between the heating wire and the bimetallic strip is difficult to guarantee. The problem of how to make the heating wire permanently and reliably make integral contact with the bimetal has long plagued the industry and is expected to be solved. It goes without saying that if the heating wire is shaped to be flattened in such a manner that a shaping station is added after the installation of the heating wire is completed by a worker at a preceding station, the aforementioned technical problems can be remedied to some extent, but this measure wastes valuable labor resources, and if the shaping is manually performed by the worker without a reasonably structured automatic shaping device, shaping efficiency and shaping effect cannot be secured. The technical solutions described below have been created in this context.

The lead-in power cord (not shown) of the aforementioned power cord box 67 is electrically connected to the aforementioned controller 8, and the aforementioned rod actuator cylinder 62 and flattening cylinder 66 are electrically connected to the controller 8. As mentioned above, since the first electrical contact i 45 and the second electrical contact ii 46 are three each, i.e. six in total, the conductive bars 64 illustrated in fig. 1 and 3 are six, each two, i.e. each pair of conductive bars 64, corresponds to one first electrical contact i 45 and one second electrical contact ii 46, and the one first electrical contact i 45 and the one second electrical contact ii 46 correspond to one refrigeration compressor motor protector 9. Since the conductor bars 64 have six conductors, the aforementioned conductor bar return springs 642 have six conductors, and since the six conductor bars 64 correspond to the first electrical contact i 45 and the second electrical contact ii 46 in a spaced-apart state, it is verified that the applicant mentioned above has contacted or released the conductor bars 64 with or from the end surfaces of the first electrical contact i 45 and the second electrical contact ii 46 on the side facing away from the clamp base 41 in a spaced-apart state by the conductor bar return spring support 643.

When the rotary disk driving mechanism 3 drives the rotary disk 2 to rotate to make the protector clamp 4 with the motor protector 9 of the refrigeration compressor located at the working position corresponding to the heating wire leveling mechanism 6 and the heating wire 94 needs to be leveled and shaped in a heating and pressurizing way, the end surface of the conducting rod 64 facing the clamp base 41 through the conducting rod return spring supporting seat 643 in a spaced state is in a state of being contacted (electrically contacted) with the end surfaces of the first electrical contact I45 and the second electrical contact II 46 due to the action of the conducting rod return spring 642, therefore, under the control of the controller 8, the power wire box 67 leads out the power wire 671 to electrify the conducting rod 64, the heating wire is heated to a red-through state under the electrification, then the leveling cylinder 66 works, the leveling cylinder 661 extends downwards outside the cylinder body to drive the leveling pressure rod clamping seat 68 to move downwards, since the set of three heating wire leveling pressing rods 69 (in this embodiment) are fixed to the horizontal clamping arms 682 of the heating wire leveling pressing rods by the clamping screws 691, the set of heating wire leveling pressing rods 69 are driven to synchronously move downward when the leveling pressing rod clamping base 68 moves downward, and the bottom surface of the heating wire leveling pressing rods 69 applies pressure to the heating wire 94 heated to a red state, i.e., pressurizes, so that the flatness of the heating wire 94 tends to be uniform. After the leveling is completed, the leveling cylinder 66 is operated in reverse to move the leveling press rod holder 68 upward together with the heating wire leveling press rods 69 in the reverse direction, and the bottom surfaces of the heating wire leveling press rods 69 are away from the heating wires 94, i.e., the heating wire leveling press rods 69 move upward and are away from the motor protector 9 of the refrigeration compressor. Meanwhile, the power supply of the leading-out power line 671 is cut off, and under the action of the controller 8, the conducting rod actuating cylinder 62 works to make the conducting rod actuating cylinder slide block 621 slide (move) in the direction departing from the conducting rod seat 63, the conducting rod actuating cylinder slide block 621 drives the conducting rod fixing seat 641 to correspondingly slide, so that the conducting rod fixing seat 641 drives a group of conducting rods 64 to move in the direction departing from the clamp base 41, under the action of overcoming the reaction force of the conducting rod return spring 642, the conducting rod return spring supporting seat 643 leaves the first electrical contact head i 45 and the second electrical contact head ii 46, at this time, the conducting rod actuating cylinder slide block position signal acquisition trigger 6211 touches the conducting rod actuating cylinder slide block position signal acquisition device 6121, so that the conducting rod actuating cylinder slide block position signal acquisition device 6121 acquires a signal and feeds the signal back to the controller 8, the rod actuation cylinder 62 is deactivated, and the rod return spring 642 is compressed and charged. Then, the rotary disc 2 is rotated by a station under the action of the rotary disc driving mechanism 3, so that the refrigeration compressor motor protector 9 which finishes shaping the heating wire 94 rotates to a station where the protector removing mechanism 7 is located along with the rotary disc 2 at the protector clamp 4, and the refrigeration compressor motor protector 9 which is located at the station of the workpiece loss detecting mechanism 5 previously carries the leveling shaping to the heating wire 94 is rotated to a station of the heating wire leveling mechanism 6, and the relay operation (action) is carried out.

The horizontal displacement acting cylinder 72, the jaw fixing base lifting acting cylinder 73 and the group of jaw acting cylinders 75 are electrically connected with the controller 8 in a control mode, namely controlled by the controller 8.

Continuing to refer to fig. 4, a first extreme position signal collector i 722 of a horizontal displacement acting cylinder slide block is fixed on the end surface of the horizontal displacement acting cylinder 72 at the end departing from the rotary disk 2, and a second limit signal collector II 723 of a sliding block of the horizontal displacement acting cylinder is fixed on the end surface of one end of the horizontal displacement acting cylinder 72 facing the rotary disk 2, a slider plunger 7211 is fixed to the bottom of the aforementioned horizontal displacement action cylinder slider 721 at a position corresponding to the horizontal displacement action cylinder slider second limit signal collector ii 723, the sliding block ram 7211 is matched with a second extreme position signal collector II 723 of the sliding block of the horizontal displacement acting cylinder, and one side, facing the first extreme position signal collector I722 of the sliding block of the horizontal displacement acting cylinder, of the sliding block 721 of the horizontal displacement acting cylinder is matched with the first extreme position signal collector I722 of the sliding block of the horizontal displacement acting cylinder; a jaw fixing seat lifting action cylinder slider ascending limit position signal collector 733 is fixed at the top of the jaw fixing seat lifting action cylinder 73, a jaw fixing seat lifting action cylinder slider descending limit position signal collector 734 is also fixed at the side of the jaw fixing seat lifting action cylinder 73, a signal collector collision block 7321 is fixed at the side of the jaw fixing seat lifting action cylinder slider 732 and at the position corresponding to the upper part of the jaw fixing seat lifting action cylinder slider descending limit position signal collector 734, the upper surface of the jaw fixing seat lifting action cylinder slider 732 is matched with the jaw fixing seat lifting action cylinder slider ascending limit position signal collector 733, and the signal collector collision block 7321 is matched with the jaw fixing seat lifting action cylinder slider descending limit position signal collector 734; in this embodiment, the aforementioned first extreme position signal collector i 722 of the sliding block of the horizontal displacement acting cylinder, the second extreme position signal collector ii 723 of the sliding block of the horizontal displacement acting cylinder, the upward extreme position signal collector 733 of the sliding block of the lifting acting cylinder of the clamping jaw fixing seat, and the downward extreme position signal collector 734 of the sliding block of the lifting acting cylinder of the clamping jaw fixing seat are travel switches, but may also be micro switches, position proximity switches, reed switches or hall sensing elements; in this embodiment, the horizontal displacement acting cylinder 72, the gripper fixing base lifting acting cylinder 73, and the set of gripper acting cylinders 75 are air cylinders.

When the motor protector 9 of the refrigeration compressor, which is subjected to flattening and shaping of the heating wire 94 by the heating wire leveling mechanism 6, is to be removed from the protector socket 42 at the station where the protector removing mechanism 7 is located, the clamping jaw fixing seat lifting acting cylinder 73 works to drive the clamping jaw fixing seat lifting acting cylinder slider 732 to move downwards, and when the downward movement reaches the degree that the signal collector striking block 7321 can excite the clamping jaw fixing seat lifting acting cylinder slider descending limit position signal collector 734 to collect a signal, the signal is fed back to the controller 8 by the clamping jaw fixing seat lifting acting cylinder slider descending limit position signal collector 734, so that the clamping jaw fixing seat lifting acting cylinder 73 stops working. Next, a set of the jaw action cylinders 75 is operated, and the pair of jaws 751 of each jaw action cylinder 75 grips the protector fixing base 91 of the refrigerant compressor motor protector 9. Then, the aforementioned lifting cylinder 73 of the jaw fixing base works in the reverse direction, the slider 732 of the lifting cylinder of the jaw fixing base moves upward, and when the upward movement reaches the degree that the upper end surface of the slider 732 of the lifting cylinder of the jaw fixing base can excite the signal collector 733 of the upward limit position of the slider of the lifting cylinder of the jaw fixing base to collect the signal, the signal collector 733 of the upward limit position of the slider of the lifting cylinder of the jaw fixing base feeds the signal back to the controller 8, and the lifting cylinder 73 of the jaw fixing base stops working. In the above process, since the jaw action cylinder fixing base 74 is fixed to the jaw fixing base lifting action cylinder sliding block 732, and since the group of jaw action cylinders 75 is fixed to the jaw action cylinder fixing base 74, and the pair of jaws 751 of the group of jaw action cylinders 75 is in the clamping state to the protector fixing base 91 at this time, when the jaw fixing base lifting action cylinder sliding block 732 is displaced upward, that is, slides upward, the jaw action cylinder fixing base 74, the group of jaw action cylinders 75, and the refrigeration compressor motor protector 9 in the clamping state are also displaced upward accordingly, the protector fixing base 91 at this time is separated from the protector socket 42, specifically, the first protection pin 92 is separated from the protection pin electrical connecting rod 43, and at the same time, the second protection pin 93 is separated from the protection pin electrical connecting clamping piece 44. Then the horizontal displacement acting cylinder 72 works to make the horizontal displacement acting cylinder sliding block 721 slide towards the direction of the first extreme position signal collector I722 of the sliding block of the horizontal displacement acting cylinder until the sliding block slides to the extent that the end surface of the sliding block 721 of the horizontal displacement acting cylinder is excited or touches the first extreme position signal collector I722 of the sliding block of the horizontal displacement acting cylinder to collect the signal, the first extreme position signal collector I722 of the sliding block of the horizontal displacement acting cylinder feeds the signal back to the controller 8, and the horizontal displacement acting cylinder 72 stops working. In the foregoing process, the horizontal displacement cylinder slide block 721 drives the jaw fixing base lifting cylinder 73, the jaw acting cylinder fixing base 74, the set of jaw acting cylinders 75, and the three refrigeration compressor motor protectors 9 in the clamped state to be displaced in the direction of the protector lead-out groove 111 described below, i.e., in the position where the protector lead-out groove 111 is located, along with the horizontal displacement cylinder slide block 721, and when the displacement reaches the position corresponding to the upper side of the protector lead-out groove 111, the set of jaw acting cylinders 75 is operated in the reverse direction, and the pair of jaws 751 of each jaw acting cylinder 75 repel each other, releasing the refrigeration compressor motor protector 9 previously in the clamped state to the protector lead-out groove 111, and leading out from the protector lead-out groove 111. Then the horizontal displacement acting cylinder 72 acts reversely, the horizontal displacement acting cylinder slide block 721 slides to the direction opposite to the above until the slide block ram 7211 is excited to touch the second extreme position signal collector II 723 of the slide block of the horizontal displacement acting cylinder, the second extreme position signal collector II 723 of the slide block of the horizontal displacement acting cylinder feeds back the signal to the controller 8, so that the horizontal displacement acting cylinder 72 stops working, because the group of clamping jaw acting cylinders 75 at this time just corresponds to the upper part of the protector socket 42 again, when the signal collector bump 7321 of the clamping jaw fixing seat lifting acting cylinder slide block 732 descending to the clamping jaw fixing seat lifting acting cylinder slide block downwards is excited by the above-mentioned clamping jaw fixing seat lifting acting cylinder 73, the signal is fed back to the controller 8 by the descending extreme position signal collector 734 of the clamping jaw fixing seat lifting acting cylinder slide block, the operation of the jaw fixing base lifting cylinder 73 is stopped, and the protector fixing base 91 is clamped again by the pair of jaws 751 of the one set of jaw operating cylinders 75 as described above, and this is repeated.

Continuing to refer to fig. 4 in conjunction with fig. 1, a pair of protector guide groove posts 11 are fixed to the table 1 at positions corresponding to both sides of the pair of jaw action cylinders 75, respectively, a protector guide groove 111 is fixed between the pair of protector guide groove posts 11, the protector guide groove 111 corresponds to the jaw 751 and is inclined downward from the direction of the rotary disk 2 toward a direction away from the rotary disk 2, and the refrigerant compressor motor protector 9 released from the pair of jaws 751 and having finished flattening and shaping the heating wire 94 is guided out from the protector guide groove 11 which is inclined.
