Cap opening device

Abstract

The invention relates to a cap opening device, and relates to the technical field of relays. The cap opening device comprises a shell, a bearing piece, a thinning piece and a cutting piece. When the sealing relay needs to be uncapped, the sealing relay is placed on the bearing part, the thinning part moves towards the sealing relay in the first direction and abuts against a pipe cap of the sealing relay to thin the pipe cap, and then the cutting part moves towards the sealing relay in the second direction and cuts the pipe cap of the sealing relay. And the pipe cap is cut, so that subsequent operators can conveniently detect parts in the pipe cap and the dryness in the pipe cap. Due to the fact that the pipe cap is thinned and then cut, the pipe cap of the sealed relay is more easily cut, the risk of chippings in the cutting process is reduced, and the reliability of uncapping of the sealed relay is improved.

[0049] Referring to Figure 1 , Figure 1 FIG. shows a schematic structural diagram of the cap-opening device 100 in some embodiments of the present application. The sealed relay 6 includes a tube cap 61. The cap-opening device 100 includes a housing 1 having an accommodation cavity Q1, a carrier and thinning member 3, and a cutting member 4. The carrier member 2 is disposed in the accommodation cavity Q1, and the carrier member 2 is configured to be rotatably connected to the housing 1 about a first axis. The carrier member 2 is used to mount the sealed relay 6. The thinning member 3 is movably connected to the housing 1 along a first direction F1 and is used to abut against the tube cap 61. The cutting member 4 is movably connected to the housing 1 along a second direction F2 and is used to cut the thinned tube cap 61. Both the first direction F1 and the second direction F2 are perpendicular to the extension direction F3 of the first axis. The thinning member 3 and the cutting member 4 are arranged at intervals along the circumferential direction of the carrier member 2.

[0050] Thus, the cap-opening device 100 includes a housing 1, a carrier member 2, a thinning member 3, and a cutting member 4. When it is necessary to open the cap of the sealed relay 6, the sealed relay 6 is placed on the carrier member 2. The thinning member 3 moves along the first direction F1 towards the sealed relay 6 and abuts against the tube cap 61 of the sealed relay 6 to first thin the tube cap 61. Then, the cutting member 4 moves along the second direction F2 towards the sealed relay 6 and cuts the tube cap 61 of the sealed relay 6, so that the tube cap 61 is cut open, which is convenient for subsequent operators to detect the components inside the tube cap 61 and the dryness inside the tube cap 61. Since thinning is performed first and then cutting, the tube cap 61 of the sealed relay 6 is more easily cut open, reducing the risk of debris generation during the cutting process, and thus improving the reliability of opening the cap of the sealed relay 6.

[0051] In some embodiments of the present application, continue to refer to Figure 1 , and in combination with referring to Figure 2 , Figure 2 FIG. shows Figure 1Schematic diagram of the structure of the moving component 5 in it. The capping device 100 further includes a moving component 5. The moving component 5 includes a first part B1, a second part B2 and a commutation component. The first part B1 is movably connected to the housing 1 along the extending direction F3 of the first axis. The second part B2 is movably connected to the housing 1 along the first direction F1. The first part B1 and the second part B2 are joined. The thinning member 3 is fixedly connected to the second part B2. The first part B1 and the second part B2 are connected by means of a commutation component. The commutation component is configured to convert the movement of the first part B1 in the extending direction F1 of the first axis into the movement of the second part B2 along the first direction towards the sealed relay 6.

[0052] The capping device 100 includes a moving component 5. The above-mentioned thinning member 3 and the cutting member 4 can both be installed on the moving component 5. In this way, when the capping device 100 needs to cap the sealed relay 6, by driving the moving component 5 to move, the thinning member 3 and the cutting member 4 can be driven to reach the acting position. Referring to the figure, there are two moving components 5 provided in the present application, and the configurations of the two moving components 5 are the same. In this way, not only can the cost be saved, but the thinning member 3 can be driven alone or the cutting member 4 can be driven alone according to requirements.

[0053] The moving component 5 includes a first part B1 and a second part B2. By driving the first part B1 to move the first part B1 along the first direction F1, with the help of the commutation component, after receiving the power given by the first part B1, it can be converted into the movement of the second part B2 along the second direction F2. Since the thinning member 3 is connected to the second part B2, the thinning member 3 can follow the second part B2 to move along the second direction F2 together, realizing approaching or leaving the sealed relay 6.

[0054] It can be understood that the tube cap 61 includes a cap edge and a cap core. Referring to the figure, along the extending direction F3 of the first axis, the cap edge has opposite first end face D1 and second end face D2. The first end face D1 is welded to the base 62, and the second end face D2 is connected to the cap core.

[0055] In some embodiments of the present application, continue to refer to Figure 1 and Figure 2 , the capping device 100 further includes a first limiting member X1 and a cooperating member P. The first limiting member X1 is fixedly connected to the housing 1, and the cooperating member P is fixedly connected to the second part B2. The first limiting member X1 is located on the path of moving along the first direction F1 towards the central axis of the carrier 2.

[0056] During the process of opening the cap of the hermetic relay 6, the thinning member 3 moves towards the hermetic relay 6 along the second direction F2. When the thinning member 3 moves towards the hermetic relay 6 along the second direction F2, once the thinning member 3 abuts against both the second end D2 surface of the cap 61 of the hermetic relay 6 and the outer peripheral surface of the cap core, the limiting member will abut against the mating member P, hindering the further movement of the limiting member towards the hermetic relay 6, reducing the risk of excessive movement of the thinning member 3 and causing damage to the hermetic relay 6. The design of the limiting member and the mating member P improves the stability and controllability of the thinning member 3 during the cap opening process. The operator does not need to worry too much about the movement range of the thinning member 3, thereby reducing the possibility of operation errors and further improving the safety and reliability of the entire cap opening process.

[0057] In some embodiments of the present application, with continued reference to Figure 1 and Figure 2 , the commutation assembly includes a first sub-part Z1, and the first sub-part Z1 and the second part B2 are connected to each other in the extending direction F3 of the first axis; the first sub-part Z1 has a first contact surface M1, the commutation assembly further includes a second sub-part Z2, the second sub-part Z2 has a second contact surface M2, and the first contact surface M1 abuts against the second contact surface M2; along the direction from the first sub-part Z1 to the second part B2, both the first contact surface M1 and the second contact surface M2 are gradually inclined in a direction away from the carrier 2; the first contact surface M1 is parallel to the second contact surface M2.

[0058] The first sub-part Z1 and the second sub-part Z2 are designed as complementary cones, and the first contact surface M1 and the second contact surface M2 can form a large-area planar fit. This design can significantly increase the effective contact area, reduce the wear between the first sub-part Z1 and the second sub-part Z2 and extend the service life, and extend the service life of the cap opening device 100.

[0059] Moreover, the first contact surface M1 and the second contact surface M2 convert the acting force in the first direction F1 into the pressure in the second direction F2. It can not only convert a large driving force in the first direction F1 into a smaller force in the second direction F2, but also convert a smaller driving force in the first direction F1 into a larger force in the second direction F2. For example, when a tightening force of 10 N is applied in the first direction F1, at a 5° inclination angle, the second direction F2 can generate a component force about 1.75 times as large, where the inclination angle is the angle between the first direction F1 and the normal direction of the inclined surface.

[0060] In this application, since the hermetic relay 6 is thinned or cut, if too much pressure in the second direction F2 is directly applied, it may cause the hermetic relay 6 to deform, crack or fail due to fatigue. Therefore, the specific inclination angle can be set close to 90°, so as to decompose the larger driving force in the first direction F1 into a smaller component force in the second direction F2, reducing the risk of the cap 61 of the hermetic relay 6 being damaged during the thinning process, and further reducing the risk of debris directly entering the cap 61 during the thinning process and contaminating the various components in the cap 61, thereby improving the reliability of the cap opening device 100.

[0061] In some embodiments of the present application, with continued reference to Figure 1 and Figure 2 , the cap opening device 100 further includes an elastic member T, and the elastic member T is disposed between the housing 1 and the second part B2.

[0062] The elastic member T plays a key buffering role during the operation of the cap opening device 100. When the thinning member 3 or the cutting member 4 contacts the cap edge of the hermetic relay 6, the elastic member T can absorb and disperse the impact force, effectively protecting the hermetic relay 6 and the structure inside the cap 61 from damage, and reducing the risk of the cap 61 of the hermetic relay 6 being damaged during the thinning process. The elastic member T can specifically be a spring.

[0063] Moreover, when the driving member Q drives the first part B1 to move towards the second part B2, the elastic member T compresses and stores energy; when the driving member Q moves in the reverse direction, the elastic member T releases energy and pushes the second part B2 to reset. When the first contact surface M1 and the second contact surface M2 convert the force in the first direction F1 into a force in the second direction F2, the elastic member T compensates for the micro-displacement of the first contact surface M1 and the second contact surface M2 through expansion and contraction, so that the two contact surfaces are closely attached, improving the force transmission efficiency, and further improving the reliability of the cap opening device 100.

[0064] In some embodiments of the present application, with continued reference to Figure 1 and Figure 2 , the cap opening device 100 further includes a driving member Q, a connecting member L and a guiding member DX.

[0065] The connecting member L has a first end D1 and a second end D2 which are oppositely arranged along the extending direction F3 of the first axis. The first end D1 is threadedly connected to the driving member Q, and the second end D2 is fixedly connected to the first part B1. The guiding member DX abuts against the opposite end faces of the connecting member L along the first direction F1, and is used to guide the connecting member L to move along the extending direction F3 of the first axis.

[0066] The driving member Q converts the rotational force into a linear motion of the connecting member L in the first direction F1 through a threaded connection, while the guiding member DX restricts the degrees of freedom of the connecting member L and only allows the connecting member L to move in the first direction F1, so that the first part B1 connected to the connecting member L can move in the first direction F1, thereby driving the second part B2 to perform a precise action. The driving member Q can be selected as a motor or a cylinder. Specifically, a scale is provided on the driving member Q. When the thinning member 3 performs a thinning process or the cutting member 4 performs a cutting process, the thickness of the thinned cap can be calculated using the scale.

[0067] In this way, the threaded connection between the driving member Q and the connecting member L can achieve precise displacement, facilitating the effective control of the displacements of the thinning member 3 and the cutting member 4. The setting of the guiding member DX enables the connecting member L to move only in the first direction F1, improving the overall operating stability of the cap-opening device 100.

[0068] Furthermore, with reference to Figure 2 , in this application, the first part B1 is connected to the connecting member L, and the two sides of the connecting member L in the second direction F2 are in contact with the inner wall of the guiding member DX. The size of the first part B1 is set to be small, and a spring is sleeved on the outer surface of the first part B1. The spring can automatically adjust its deformation according to the gap between the connecting member L and the guiding member DX, so that the connecting member L can maintain stable contact with the inner wall of the guiding member DX during the movement process, effectively reducing the friction and wear between the connecting member L and the guiding member DX caused by the change of the gap. Moreover, the spring can absorb and disperse the impact and vibration generated during the operation process. This buffering effect protects the connecting member L and the guiding member DX and extends the service life of the device.

[0069] In some embodiments of this application, with continued reference to Figure 1 and Figure 2 , the cap-opening device 100 further includes a blowing member 7. The blowing member 7 is disposed on the housing 1, and the blowing member 7 is used to blow air towards the cap 61.

[0070] During the thinning process of the cap 61 of the sealed relay 6 by the thinning member 3, debris, dust or other impurities will be generated. The blowing member 7 blows air towards the cap 61 of the sealed relay 6, blowing the debris and impurities to the bottom of the housing 1, maintaining the cleanliness of the interior and surrounding environment of the sealed relay 6 after the cap is opened, and reducing the influence of impurities on the performance of the sealed relay 6. Specifically, in this application, the blowing member 7 is turned on when the thinning member 3 is operating. Since the sealed relay 6 is not uncapped during the entire thinning process, the blowing member 7 will not blow the debris into the sealed relay 6 during the whole process. Then, when the cutting member 4 is turned on, the blowing member 7 is not turned on.

[0071] In some embodiments of this application, with continued reference to Figure 1, the housing further has a storage cavity. The accommodation cavity Q1 is used to place operating components such as a hermetic relay and a carrier 2; while the storage cavity Q2 is used to store the debris blown by air. The cap-opening device 100 further includes a negative-pressure member 8, and the negative-pressure member 8 is disposed at the opening where the accommodation cavity Q1 communicates with the storage cavity Q2.

[0072] Among them, the accommodation cavity Q1 is specifically used to place the hermetic relay 6, so that the hermetic relay 6 has a fixed and dedicated space. The storage cavity Q2 is used to store the debris generated during the air blowing process, reducing the risk of these debris polluting the environment or affecting other parts of the equipment. The negative-pressure member 8 forms a local vacuum at the communication port between the accommodation cavity Q1 and the storage cavity Q2, and quickly sucks the debris blown to the bottom of the accommodation cavity Q1 from the accommodation cavity Q1 into the storage cavity Q2 for storage. Among them, the negative-pressure member 8 can be selected as an air extraction pump or a compressor, further reducing the risk of debris entering the hermetic relay 6 when the cutting member 4 performs cap-opening treatment on the hermetic relay 6 later. And the negative-pressure member 8 can form a closed-loop system of positive-pressure air blowing and negative-pressure adsorption with the above-mentioned air blowing member 7. The negative-pressure member 8 and the air blowing member 7 have a synergistic effect. The air blowing member 7 blows the surface of the tube cap 61 through positive pressure, and at the same time the negative-pressure member 8 collects the debris by negative pressure to achieve efficient cleaning.

[0073] In some embodiments of the present application, continue to refer to Figure 1 , and in combination with reference to Figure 3 and Figure 4 , Figure 3 shows Figure 1 the structural schematic diagram of the combination of the carrier 2 and the hermetic relay 6 in Figure 4 mounted on the calibration member 9, Figure 1 the structural schematic diagram of the second placement member W2 and the rotating member XZ in Figure 5 shows Figure 1Structural schematic diagram of the carrier 2 and the second object W2 in an assembled state. The cap opening device 100 further includes a calibration member 9, a first object W1, and a second object W2. The calibration member 9 is fixedly connected to the housing 1. The calibration member 9 includes a calibration surface M1 perpendicular to the extension direction F3 of the first axis, and the calibration member 9 is used to calibrate the combination of the pre-assembled sealed relay 6 and the carrier 2. The first object W1 is disposed in the accommodation cavity Q1. The first object W1 includes a first object surface WM1 perpendicular to the extension direction F3 of the first axis. The first object surface WM1 is used to place the combination of the pre-assembled sealed relay 6 and the carrier 2. The second object W2 is disposed in the accommodation cavity Q1. The second object W2 includes a second object surface WM2 perpendicular to the extension direction F3 of the first axis. The second object surface WM2 is used to place the combination of the sealed relay 6 and the carrier 2 after being calibrated by the calibration member 9. Among them, along the extension direction F3 of the first axis, the carrier 2 and the sealed relay 6 can move relative to each other; the distance between the calibration surface M1 of the carrier 2 and the first object surface WM1 along the extension direction F3 of the first axis is the first dimension, and the side surface of the thinning member 3 facing away from the carrier 2 along the extension direction F3 of the first axis and the second object surface WM2 along the first axis.

[0074] It can be understood that during the cap opening process, the sealed relay 6 is first installed on the carrier 2, and then the combination of the sealed relay 6 and the carrier 2 is placed on the first object surface WM1 for thinning and cutting operations. However, when placing the combination, it is difficult for the cutting member 4 and the thinning member 3 to directly abut against both the second end D2 surface of the above-mentioned tube cap 61 and the outer peripheral surface of the cap core. It is necessary to repeatedly debug to make the cutting member 4 or the thinning member 3 align with the second end D2 surface of the tube cap 61 and the outer peripheral surface of the cap core, which is likely to damage the sealed relay 6.

[0075] In this application, by providing the calibration member 9, before the combination is placed on the second object surface WM2, the relative positions of the carrier 2 and the sealed relay 6 are first calibrated, and then the calibrated combination is placed on the second object surface WM2, reducing the risk of damaging the sealed relay 6 and improving the cap opening efficiency. Specifically, in this application, the structure of the calibration member 9 is a U-shaped groove C is opened on a flat plate, and the cap edge of the sealed relay 6 can be stuck on the calibration surface M1 of the calibration member 9.

[0076] In this application, the first object placement member W1 is used to place the uncalibrated assembly as the initial positioning station. The second object placement member W2 is used to place the calibrated assembly as the precision machining station. The calibration surface M1 of the calibration member 9 is perpendicular to the first axis and is used to calibrate the position of the pre-assembled combination of the sealed relay 6 and the carrier member 2 in the extension direction F3 of the first axis. It can repeatedly adjust the relative position between the sealed relay 6 and the carrier member 2 so that the second end D2 surface of the above-mentioned sealed relay 6 can abut against the calibration surface M1, so that when the assembly is placed on the second object placement member W2, the sealed relay 6 can be directly thinned and cut, further improving the reliability of the capping of the capping device 100.

[0077] Moreover, the phased design of the calibration member 9, the first object placement surface WM1, and the second object placement surface WM2 allows the current sealed relay 6 to be thinned or cut while the simulation cutting member 4 and the thinning member 3 preview the path of the next workpiece, further improving the capping efficiency of the capping device 100.

[0078] In some embodiments of this application, continue to refer to Figure 1 , and in combination with reference to Figure 6 , Figure 6 shows Figure 1 a schematic structural diagram of the lid GZ, the rotating shaft ZZ, and the protection member BH in an assembled state in

[0079] During the cutting by the cutting member 4 and the thinning by the thinning member 3, the sealed relay 6 needs to rotate around the first axis. The design of the lid GZ effectively reduces the risk that after capping, the base 62 and the cap 61 are separated, resulting in the base 62 flying out of the housing 1 due to inertial force, greatly improving the safety of the capping operation. And the protection member BH is sleeved on the lead pins YJ. It not only allows the lead pins YJ to rotate freely when the sealed relay 6 rotates during the thinning and cutting processes, but also the protection member BH is sleeved on the lead pins YJ, reducing the damage to the lead pins YJ during assembly, adjustment, or transportation.

[0080] And by detachably connecting the cover GZ to the housing 1, when the cap-opening device 100 operates, the cover GZ is connected to the housing 1, making the accommodation cavity Q1 in the housing 1 a closed space, preventing the internal components of the housing 1 from being externally contaminated, and further maintaining the cleanliness and performance stability of the sealed relay 6. The design of the detachable connection also enables the convenient installation or disassembly of the cover GZ when needed, facilitating maintenance and repair. Among them, the detachable connection can be achieved by snap connection or threaded connection, etc.

[0081] In addition, specifically in this application, continue to refer to Figure 1 and Figure 4 , the sealed relay 6 can be carried by providing an installation groove on the carrier 2 and installing the tube cap 61 of the sealed relay 6 in the installation groove. This application also includes a rotating member XZ, and the carrier 2 is detachably connected to the rotating member XZ. The rotating member XZ can be set as a motor rotor or a gear shaft, etc.

[0082] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0083] The above embodiments only represent several implementation manners of this application, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of this application, several modifications and improvements can still be made, and these all belong to the protection scope of this application. Therefore, the protection scope of the patent of this application should be subject to the appended claims.
