Description

Technical Field

[0002] At present, in the industrial field, pressure vessels equipped with self-sealing joints are generally used for quantitative canning of electrolyte products. Due to the chemical characteristics of the electrolyte, air needs to be isolated during canning and turnover. Therefore, the pressure vessel uses a sealed container such as a steel cylinder, and multiple male heads equipped with self-sealing joints are connected to the sealed container. The canned hose is connected to the female head equipped with a self-sealing joint. The hose is divided into a material pipe and a gas pipe. The material pipe is used to transport the electrolyte, and the gas pipe is used to replace the gas in the sealed container to ensure that the steel cylinder is filled with inert gas.

[0003] The prior art generally adopts a manual quantitative canning method. When canning is required, the cylinder is manually placed on the scale, the female end of the hose and the male end of the sealed container are manually connected, and then the ball valve is opened to start canning. When the female end is inserted or pulled out before or after canning, a small amount of residual fluid will be sprayed out due to the pressure in the tube, which is easy to spray on the operator. Some corrosive fluids will cause certain harm to the operator. At the same time, manual connection of the hose is time-consuming and laborious, which is not conducive to large-scale industrial quantitative canning. Summary of the invention

[0072] The present application will be described in detail below in conjunction with the various embodiments shown in the accompanying drawings. However, these embodiments do not limit the present application, and any structural, methodological, or functional changes made by a person of ordinary skill in the art based on these embodiments are all included in the protection scope of the present application.

[0073] At present, the quantitative filling of electrolyte in the industrial field is realized by using a sealed container equipped with a self-sealing male connector and a hose equipped with a self-sealing female connector. Since the plugging and unplugging of the self-sealing connector is designed for manual operation, it is difficult to achieve fully automated plugging and unplugging, so semi-automatic manual quantitative filling is usually used.

[0074] During canning, it is necessary to manually connect the female end of the hose and the male end of the sealed container, and then open the ball valve to start canning. When inserting or pulling out the female end before and after canning, a small amount of residual fluid will be sprayed out due to the pressure in the tube, which may easily spray onto the operator. Some corrosive fluids may cause certain harm to the operator. At the same time, manual connection of the hose is time-consuming and labor-intensive, which is not conducive to large-scale industrial quantitative canning.

[0075] In order to solve the above problems, the applicant has developed an automatic plug-in and pull-out mechanism for a self-sealing joint, which can realize the automatic unlocking and pulling out and automatic locking and inserting operations of the self-sealing joint, thereby greatly improving the automation of quantitative filling.

[0076] Specifically, see Figure 1 , Figure 1 It is a schematic diagram of an application scenario of the automatic plug-in and pull-out mechanism of the self-sealing joint of the present application, which includes a barrel 1 with a self-sealing joint male head 10 on the top surface, a hose 2 with a self-sealing joint female head 20 at the end, and a hose rack 3 with a placement sleeve 30.

[0077] Specifically, the hose 220 may include two hoses, namely, a material hose and an air hose. Accordingly, the top surface of the drum 1 may be provided with two self-sealing male joints 10 respectively matching the self-sealing female joints 20 of the material hose and the air hose, and the hose rack 3 may be provided with two placement sleeves 30 respectively matching the self-sealing female joints 20 of the material hose and the air hose.

[0078] The self-sealing female joint 20 comprises a joint body 201 and a sliding sleeve 202 located at the end of the joint body 201 . The sliding sleeve 202 can move along the axial direction of the joint body 201 to unlock or lock the self-sealing joint.

[0079] When the perfusion is idle, the self-sealing female connector 20 of the hose 2 can be inserted into the placement sleeve 30; when quantitative perfusion is required, the self-sealing female connector 20 of the hose 2 needs to be pulled out from the placement sleeve 30 and inserted into the corresponding self-sealing male connector 10.

[0080] The following is a detailed description of the structure of the automatic plug-in and pull-out mechanism of the self-sealing joint of this application. Figure 2 , Figure 2 It is a structural schematic diagram of an embodiment of the automatic plugging and unplugging mechanism of the self-sealing joint of the present application.

[0081] like Figure 2 As shown, the automatic plugging and unplugging mechanism includes a first mounting plate 40 and a second mounting plate 50 which are stacked and spaced apart.

[0082] The first mounting plate 40 is connected to the fixing member 60 , and a first clamping assembly 70 is provided on the side of the first mounting plate 40 facing the second mounting plate 50 . The first clamping assembly 70 is used to clamp the connector body 201 of the self-sealing connector female connector 20 .

[0083] A second clamping assembly 80 is disposed on a side of the second mounting plate 50 facing away from the first mounting plate 40 . The second clamping assembly 80 is used to clamp the sliding sleeve 202 of the self-sealing joint female head 20 .

[0084] A first lifting assembly 90 is arranged between the first mounting plate 40 and the second mounting plate 50 . The first lifting assembly 90 is used to drive the first mounting plate 40 and the second mounting plate 50 to move relative to each other, so as to drive the sliding sleeve 202 to move axially along the joint body 201 .

[0085] It can be understood that when the first clamping assembly 70 and the second clamping assembly 80 respectively clamp the joint body 201 and the sliding sleeve 202 of the self-sealing joint female head 20, the control action of the first lifting assembly 90 can drive the sliding sleeve 202 to move axially along the joint body 201, thereby realizing the unlocking and locking operation of the self-sealing joint female head 20.

[0086] For example, when it is necessary to unplug the self-sealing connector female head 20, the sleeve 202 can be controlled to slide toward the connector body 201, thereby unlocking the self-sealing connector female head 20, and then the hose 2 can be pulled out by moving the fixing member 60; when it is necessary to insert the self-sealing connector female head 20, the unlocked state can be maintained by controlling the distance between the first mounting plate 40 and the second mounting plate 50. After the self-sealing connector female head 20 is inserted into the male head, the sleeve 202 is controlled to slide in the direction away from the connector body 201, thereby locking the self-sealing connector female head 20, and then the first clamping assembly 70 and the second clamping assembly 80 are controlled to be loosened to realize the insertion operation of the self-sealing connector female head 20.

[0087] See also Figure 3 , Figure 3 Schematic diagram of the structure of the first clamping assembly 70 of the present application. Figure 3 As shown, the first clamping assembly 70 includes a first clamping cylinder 701 and a pair of first clamping blocks 703 .

[0088] Specifically, the first clamping cylinder 701 is arranged on the bottom surface of the first mounting plate 40, and two first output ends 702 are arranged opposite to each other on one side of the first clamping cylinder 701, and the first clamping cylinder 701 can drive the two first output ends 702 to move relative to or away from each other.

[0089] A pair of first clamping blocks 703 are respectively arranged on the two first output ends 702. Specifically, in order to facilitate the first clamping blocks 703 to clamp the joint body 201 of the self-sealing joint, the clamping surface of the first clamping block 703 can be provided with a semicircular clamping groove 704 matching the joint body 201 of the automatic joint, so that the pair of first clamping blocks 703 cooperate to clamp the joint body 201 of the self-sealing joint.

[0090] In order to further improve the clamping stability of the first clamping block 703 on the self-sealing joint, please refer to Figure 4 , Figure 4 Schematic diagram of the structure of an embodiment of the self-sealing female connector 20 of the present application. Figure 4As shown, the inner end of the connector body 201 of the automatic connector female head can also be connected to the positioning tube 203, and convex rings can be set at both ends of the positioning tube 203, so that a positioning groove 204 matching the first clamping block 703 is formed between a pair of convex rings, so that a pair of first clamping blocks 703 can be clamped in the positioning groove 204, thereby improving the stability of the first clamping block 703 clamping the connector body 201.

[0091] It is understandable that when a positioning tube 203 is arranged at the inner end of the connector body 201 , the semicircular groove 704 on the clamping surface of the first clamping block 703 should be configured to match the positioning groove 204 on the peripheral surface of the positioning tube 203 , so as to ensure clamping stability.

[0092] See also Figure 5 , Figure 5 Schematic diagram of the structure of the second clamping assembly 80 of the present application. Figure 5 As shown, the second clamping assembly 80 includes a second clamping cylinder 801 and a pair of second clamping blocks 803 .

[0093] Specifically, the second clamping cylinder 801 is arranged on the bottom surface of the second mounting plate 50, and two second output ends 802 are arranged opposite to each other on one side of the second clamping cylinder 801, and the second clamping cylinder 801 can drive the two second output ends 802 to move relative to or away from each other.

[0094] A pair of second clamping blocks 803 are respectively arranged on the two second output ends 802 .

[0095] It should be noted that in order to ensure that the first clamping assembly 70 and the second clamping assembly 80 clamp the joint body 201 and the sliding sleeve 202 of the self-sealing joint respectively at the same time, the first output end 702 and the second output end 802 should be arranged on the same side.

[0096] Furthermore, in order to achieve automatic centering of the second clamping block 803 when clamping the sleeve 202, and at the same time make the second clamping block 803 compatible with self-sealing joints of multiple specifications, the clamping surface of the second clamping block 803 is also provided with a V-shaped groove 804, so that a pair of V-shaped grooves 804 of the second clamping block 803 can cooperate to clamp the sleeve 202.

[0097] It can be understood that the design of the V-shaped groove 804 can automatically adjust the position of the sleeve 202 to the center of the V-shaped groove 804 when clamping, thereby achieving a certain degree of automatic centering. When inserting the self-sealing joint female head 20, it is only necessary to adjust a pair of second clamping blocks 803 to the top of the self-sealing joint male head 10, and control the pair of second clamping blocks 803 to clamp the sleeve 202 of the self-sealing joint female head 20, so as to ensure that the sleeve 202 is aligned with the self-sealing joint male head 10.

[0098] Furthermore, in order to prevent the second clamping block 803 from slipping when clamping the sliding sleeve 202, the second clamping assembly 80 also includes a scraper 805, which is respectively arranged on a side of the second clamping block 803 facing the first clamping block 703 and a side of the second clamping block 803 away from the first clamping block 703, and each scraper 805 includes a clamping end close to the second clamping block 803 on the other side, and the clamping end of the scraper 805 extends out of the corresponding clamping surface of the second clamping block 803 along the clamping direction, and the clamping end of the scraper 805 is provided with a V-shaped notch 806 matching the V-shaped groove 804.

[0099] Since the V-shaped notch 806 at the clamping end of the scraper 805 extends beyond the clamping surface of the second clamping block 803 , the scraper 805 can engage the end surface of the sliding sleeve 202 during clamping, thereby preventing the sliding sleeve 202 from slipping during pushing and pulling.

[0100] It should be noted that in the above-mentioned embodiment, the clamping surface of the first clamp 703 is arranged with a semicircular groove 704, and the clamping surface of the second clamp 803 is arranged with a V-shaped notch 804. In other embodiments, the clamping surfaces of the first clamp 703 and the second clamp 803 can also be arranged with a V-shaped notch 804, which can also achieve the effect of this embodiment.

[0101] See also Figure 6 , Figure 6 Schematic diagram of the structure of the first lifting assembly 90 of the present application. Figure 6 As shown, the first lifting assembly 90 includes a first lifting cylinder 901 , a first transition rod 902 and a guide rod 903 .

[0102] The first lifting cylinder 901 is arranged on a side of the first mounting plate 40 away from the second mounting plate 50 , and an output end of the first lifting cylinder 901 extends along the first mounting plate 40 toward the second mounting plate 50 .

[0103] One end of the first transition rod 902 is connected to the output end of the first lifting cylinder 901 , and the other end is connected to the first mounting plate 40 .

[0104] The guide rod 903 is extended along the first mounting plate 40 toward the second mounting plate 50 , one end of the guide rod 903 is connected to the second mounting plate 50 , and the other end thereof penetrates through the first mounting plate 40 .

[0105] The first lifting cylinder 901 can drive the second mounting plate 50 to rise and fall through the first transition rod 902 by driving the first output end 702 to extend and retract. In order to further improve the stability of the second mounting plate 50 during the lifting movement and limit the maximum displacement of the second mounting plate 50, a guide block 904 is further provided on the side of the first mounting plate 40 facing the second mounting plate 50, and the guide rod 903 and the first transition rod 902 are arranged through the guide block 904. The guide block 904 can limit the minimum spacing between the first mounting plate 40 and the second mounting plate 50, and further limit the lifting direction of the second mounting plate 50 to avoid displacement.

[0106] When inserting the self-sealing joint female head 20, it is necessary to first align the self-sealing joint female head 20 and the self-sealing joint male head 10. This alignment operation often has a large deviation, which affects the subsequent insertion operation. To solve this problem, please refer to Figure 2 In one embodiment, the automatic plug-in / pull-out mechanism further includes a floating deviation correction assembly 100 arranged between the first mounting plate 40 and the fixing member 60 .

[0107] Specifically, see Figure 7 , Figure 7 The floating correction assembly 100 of the present application is a schematic structural diagram of an embodiment of the present invention. The floating correction assembly 100 comprises an upper floating positioning plate 1001, a lower floating positioning plate 1002, a connecting column 1003, a first universal ball 1004 and a second universal ball (not shown in the figure).

[0108] The upper floating positioning plates 1001 are stacked and arranged at intervals on one side of the first mounting plate 40 ; the lower floating positioning plates 1002 are stacked and arranged at intervals on the other side of the first mounting plate 40 . The upper floating positioning plates 1001 and the lower floating positioning plates 1002 are fixed to the fixing member 60 .

[0109] The connecting column 1003 is arranged between the upper floating positioning plate 1001 and the lower floating positioning plate 1002 to connect the upper floating positioning plate 1001 and the lower floating positioning plate 1002 into a whole.

[0110] Specifically, in this embodiment, four connecting columns 1003 arranged at four corners are provided between the upper floating positioning plate 1001 and the lower floating positioning plate 1002 .

[0111] A plurality of first universal balls 1004 are arranged in the gap between the upper floating positioning plate 1001 and the first mounting plate 40 ; a plurality of second universal balls (not shown) are arranged in the gap between the first mounting plate 40 and the lower floating positioning plate 1002 .

[0112] It is understandable that the upper floating positioning plate 1001 and the lower floating positioning plate 1002 can cooperate to form a deviation correction space, so that the first mounting plate 40 can translate in the deviation correction space. In this embodiment, in order to provide the first mounting plate 40 with sufficient translation space and limit the first mounting plate 40 at the same time, avoidance notches 401 for avoiding the corresponding corner connecting columns 1003 are provided at both ends of one side of the first mounting plate 40.

[0113] In other embodiments, the structural design of the first mounting plate 40 and the number of connecting columns 1003 can also be adjusted based on actual working conditions, so that the first mounting plate 40 can be translated in any direction in the correction space and be limited in the correction space, thereby achieving the effect of the present embodiment.

[0114] Since a chamfer is provided at the end of the self-sealing joint male head 10, under the guiding effect of the chamfer, the first mounting plate 40 can freely translate and adjust its position in the correction space to achieve effective alignment under large deviations, thereby effectively improving the accuracy and reliability of the automatic plugging and unplugging process of the automatic plugging and unplugging mechanism, reducing the requirements for system positioning accuracy, and thus reducing equipment costs.

[0115] Further, in order to facilitate the first clamping assembly 70 and the second clamping assembly 80 to move to the self-sealing joint, please refer to Figure 2 In one embodiment, the automatic plug-in and unplug mechanism also includes a second lifting assembly 110, which is used to drive the lifting of the fixing member 60, thereby synchronously driving the lifting of the first clamping assembly 70 and the second clamping assembly 80. Therefore, when the first clamping assembly 70 and the second clamping assembly 80 are shifted to the self-sealing joint female head 20 to be pulled out or the self-sealing joint male head 10 to be inserted, only the first clamping assembly 70 and the second clamping assembly 80 can be moved to the top, and then the first clamping assembly 70 and the second clamping assembly 80 are lifted and lowered by the second lifting assembly 110 to complete the shifting process.

[0116] Specifically, see Figure 8 , Figure 8 1 is a schematic diagram of the structure of an embodiment of the second lifting assembly 110 of the present application. Figure 8 As shown, the second lifting assembly 110 includes a fixed back plate 1101 , a guide rail 1102 , a slider 1106 , a second lifting cylinder 1103 and a second transition rod 1104 .

[0117] The fixed back plate 1101 can be arranged on the addressing and positioning device. The guide rail 1102 is arranged on the fixed back plate 1101 along the direction from the first mounting plate 40 to the second mounting plate 50 ; the slider is slidably arranged on the guide rail 1102 , and the slider 1106 is connected to the fixing member 60 .

[0118] The second lifting cylinder 1103 is fixed on the fixed back plate 1101 , and the output end of the second lifting cylinder 1103 is extended along the first mounting plate 40 toward the second mounting plate 50 .

[0119] One end of the second transition rod 1104 is connected to the output end of the second lifting cylinder 1103 , and the other end is connected to the slider 1106 .

[0120] It can be understood that the second lifting cylinder 1103 can drive the slider 1106 to slide along the guide rail 1102, thereby driving the fixing member 60 to slide along the guide rail 1102, and synchronously driving the first clamping assembly 70 and the second clamping assembly 80 to rise and fall synchronously.

[0121] For automated control, see Figure 8 , a first induction switch 1105 is provided on the fixed back plate 1101; please refer to Figure 7 The upper floating positioning plate 1001 is provided with a second induction switch 1005 that cooperates with the first induction switch 1105 .

[0122] When the second lifting cylinder 1103 drives the upper floating positioning plate 1001 to move to the first sensing switch 1105 and senses the second sensing switch 1005, a stop working signal can be sent to stop the second lifting cylinder 1103 from continuing to work. At this time, the upper clamping assembly and the lower clamping assembly move to the upper limit.

[0123] It should be noted that the above-mentioned embodiment only exemplarily describes the technical solution of the first induction switch 1105 and the second induction switch 1005 cooperating to limit the upper limit of movement. In other embodiments, other induction switches may be provided on the fixed back plate 1101 to cooperate with the second induction switch 1005 to limit the lower limit of movement. The second induction switch 1005 may not be arranged on the upper floating positioning plate 1001. For example, it may be directly arranged on the first mounting plate 40, the second mounting plate 50, the fixing member 60, etc., so as to realize the movement limit of the upper clamping assembly and the lower clamping assembly, and the effect of the present embodiment can be achieved.
