[0038] In order to make the purpose, technical scheme and advantages of the present invention clearer, the technical scheme of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The embodiments described in this application are only part of the embodiments of the present invention, not all of them. Based on the spirit of the present invention, other embodiments obtained by ordinary technicians in this field without creative work are all within the scope of protection of the present invention.

[0039] like Figure 1 , Figure 2 As shown, embodiment 1 of the present invention discloses a box sealing device for an electric energy meter assembly line, comprising: a support 29, a conveying mechanism, a box storage mechanism, a box taking mechanism, a box transfer mechanism, and a gluing mechanism. The conveying mechanism, the box storage mechanism, the box taking mechanism, the box transfer mechanism, and the gluing mechanism are all installed on the top of the support 29. The conveying mechanism is arranged on one side of the box transfer mechanism, and the outlet of the conveying mechanism is close to the inlet of the box transfer mechanism, and is used to transfer the qualified electric energy meter transferred from the previous process to the box transfer mechanism. The box storage mechanism is arranged above the box transfer mechanism, and its outlet is located above the inlet of the box transfer mechanism, and is used to store the packaging boxes folded and placed horizontally. The box taking mechanism is arranged at the entrance of the box storing mechanism, and is used to take out the packaging box folded and placed in the box storing mechanism and send it into the box transferring mechanism, and cooperate with the box transferring mechanism to restore the packaging box from a folded state to an expanded state; the box transferring mechanism is used to receive the packaging box, and when the packaging box is loaded with the electric energy meter, it conveys the packaging box to the gluing mechanism; the gluing mechanism is arranged on both sides of the box transferring mechanism, and is used to close the box covers on both sides of the packaging box after the electric energy meter is loaded and seal the box with glue.

[0040] Furthermore, the conveying mechanism includes: a conveyor belt 1, a cylinder 2, a push plate 3 and a baffle 4. The conveyor belt 1 is installed on a support 29 and is located on one side of the box-transferring mechanism. The conveyor belt 1 is used to receive qualified electric energy meters transmitted from the previous process. A baffle 4 is installed on the support 29 near the end of the conveyor belt 1. The vertical bisector of the baffle 4 is the same as the conveying direction of the conveyor belt 1, and is used to block the electric energy meter transported to the end by the conveyor belt 1. The outlet of the conveying mechanism is provided at the end of the conveyor belt 1 and on one side of the baffle 4, and the outlet of the conveying mechanism is directly opposite to the inlet of the box-transferring mechanism. A thrust mechanism is installed on the support 29 on one side of the baffle 4. The thrust mechanism is preferably a cylinder 2. A push plate 3 is fixed to the output end of the cylinder 2. The push plate 3 is arranged vertically to the baffle 4, and one side of the push plate 3 is in contact with the baffle 4. The cylinder 2 is used to drive the push plate 3 to push the electric energy meter along a direction perpendicular to the conveying direction of the conveyor belt 1, and push the electric energy meter blocked by the baffle 4 from the conveyor belt 1 to the outlet of the conveying mechanism, and finally push the electric energy meter into the inlet of the box transfer mechanism.

[0041] In a preferred but non-limiting embodiment of the present invention, a first sensor is provided on the upper side of the baffle 4 , and the first sensor is preferably a photoelectric sensor, which pauses the conveyor belt 1 when it detects that the electric energy meter reaches the baffle 4 .

[0042] An automatic revolving door is provided on one side of the conveyor belt 1 at the exit of the conveying mechanism. Figure 3 As shown, the automatic reset revolving door includes: two rotating columns 30 and two auxiliary plates 31. The two rotating columns 30 are symmetrically arranged and can be rotatably mounted on the top of the support 29. An auxiliary plate 31 is fixedly mounted on the side of each rotating column 30. The initial positions of the two auxiliary plates 31 are parallel to the push plate 3 and can rotate with the rotating column 30 to open the revolving door, so that the electric energy meter can pass between the two rotating columns 30.

[0043] Furthermore, the rotating column 30 is connected to the support 29 by a reset spring, and the reset spring is preferably a roll spring, so that the rotating column 30 can have the ability to rotate automatically. When the cylinder 1 2 moves the push plate 3 to push the electric energy meter, the electric energy meter pushes the two auxiliary plates 3 from the middle, so that the two auxiliary plates 31 rotate outward, open the automatic reset rotating door, and allow the electric energy meter to enter the box transfer mechanism.

[0044] Combination Figure 4As shown, the box-transfer mechanism includes: a transmission chain 9, a limiting bracket 10, a support plate 11 and a limiting plate 32. The support plate 11 is installed on the top of the bracket 29, and its length direction is parallel to the transmission direction of the conveyor belt 1, and the side of the support plate 11 close to the outlet of the conveying mechanism is the inlet of the box-transfer mechanism. Two transmission chains 9 are symmetrically arranged on the left and right sides of the support plate 11, and a plurality of limiting brackets 10 are evenly installed on the top of each transmission chain 9, which are located between the limiting brackets 10 of the two transmission chains 9 and are used to clamp the packaging box of the electric energy meter, and transport the packaging box under the drive of the transmission chain 9.

[0045] The limit plate 32 is fixedly mounted on the top of the support 29 and is located below the support plate 11. A box opening rack 16 is provided on the side of the limit plate 32 close to the entrance of the box transfer mechanism. The box opening rack 16 is used to cooperate with the support plate 11 and the box taking mechanism to convert the folded packaging box into a square cylindrical open state. In addition, since the present invention folds the packaging box horizontally and places it in the box storage mechanism, when the packaging box changes from a folded state to an open state, its opening direction is the same as the direction in which the conveying mechanism pushes the electric energy meter into the box transfer mechanism, so that the conveying mechanism can push the electric energy meter into the packaging box located at the entrance of the box transfer mechanism, and this process does not require human participation.

[0046] Furthermore, the box opening rack 16 is cylindrical, and its axial direction is perpendicular to the conveying direction of the box transfer mechanism. When the packaging box contacts the box opening rack 16, the box will not be stuck. After the packaging box is expanded into a square tube shape and pulled down, it will be stuck between the two pairs of limit brackets 10, and then move with the box transfer mechanism.

[0047] Furthermore, a second sensor is provided at the top of the support 29 corresponding to the position of the exit of the box transfer mechanism. The second sensor is preferably a photoelectric sensor, which is used to identify whether the packaging box follows the limiting bracket to move to the exit of the box delivery mechanism, and when the packaging box and the limiting bracket 10 move to the position of the exit of the box transfer mechanism, the driving motor of the transmission chain 9 is paused, and the electric energy meter is pushed into the packaging box through the cylinder 2.

[0048] The box storage mechanism includes: a box frame 12, which is fixedly mounted on a support 29 and is located above the box transfer mechanism. The box frame 12 includes a bottom plate, a side plate and a top plate. The packaging box folded into a pancake shape is pre-placed on the bottom plate of the box frame 12 for storage, and the packaging box is placed horizontally so that its two end openings face the left and right sides of the box storage mechanism respectively. The front ends of the bottom plate and the top plate have a downward tilt angle, and the front ends of the bottom plate, the side plate and the top plate have anti-falling sharp corners 15 bent toward the center, which have a certain limiting effect on the four sides of the packaging box to prevent it from falling automatically. A slide groove is provided in the middle of the bottom plate, and a screw rod rotatably connected to the bottom end of the box frame 12 is provided below the slide groove, and the axial direction of the screw rod is parallel to the sliding direction of the slide groove. A box pressing motor 13 is provided at the bottom of the box frame 12, and the screw rod is drivingly connected to the output end of the box pressing motor 13, and a box pressing plate 14 is threadedly connected to the screw rod, and the box pressing plate 14 passes through the slide slot and extends to the top of the box frame 12. The box pressing plate 14 slides along the slide slot, and can adjust the storage space size of the box storage mechanism to meet the storage requirements of packaging boxes of different sizes. In addition, after the packaging box is placed in the storage mechanism, the box pressing motor 13 drives the box pressing plate 14 to move, which can automatically press the packaging box and push the packaging box to the exit of the box storage mechanism so that the box taking mechanism can grab the packaging box.

[0049] Furthermore, a third sensor is provided on the box pressing plate 14, and the third sensor is preferably a patch pressure sensor. When the pressure value detected by the pressure sensor is less than the set value, the box pressing motor 13 moves toward the front end until the pressure value reaches the set value and stops, that is, the packaging box is automatically pushed to keep the packaging box in a vertical position. The pressure setting value here is relatively small, and the force required to get out of the anti-fall corner 15 will not be exceeded when pushing.

[0050] The box-taking mechanism is set at the exit of the box-depositing mechanism. Figure 5 , Figure 6As shown, the box-taking mechanism includes: a support column 21, a bracket 22 and a connecting frame 23. The support column is fixed to the ground. The top of the support column 21 is hinged to the bracket 22. A cylinder 28 is arranged between the bracket 22 and the support column 21. The cylinder 28 can control the movable angle of the bracket 22. The bracket 22 is hinged to the connecting frame 23. A cylinder 3 27 is arranged between the bracket 22 and the connecting frame 23. The cylinder 3 can control the angle between the bracket 22 and the connecting frame 23. The front end of the connecting frame 23 is fixed with a cylinder 26. The front end of the cylinder 26 is fixed with a suction cup frame 24. The suction cup frame 24 is fixed with a pneumatic suction cup 25. The pneumatic suction cup 25 is directly facing the outlet of the box storage mechanism. The front side of the limit plate 32 (i.e., the inlet side of the box transfer mechanism) is provided with a box opening frame 16. The box opening frame 16 is arranged horizontally, and its axial direction is perpendicular to the length direction of the support plate 11. The packaging box is placed on the box storage mechanism in a folded state, and the packaging box is placed horizontally so that the openings at both ends face the left and right sides of the box storage mechanism respectively. The pneumatic suction cup 25 sucks the side of the folded packaging box, and then the cylinder 2 26 retracts to pull the packaging box out of the box storage mechanism. The cylinders 3 27 and 4 28 are actuated to move the packaging box downward. During the movement, the lower side of the folded packaging box first contacts the support plate 11. When the movement continues, the packaging box is restricted by the box opening frame 16 and the support plate 11, which will squeeze the packaging box from the folded state into a square cylinder, thereby opening the packaging box and transferring it to the support plate 11 of the box transfer mechanism.

[0051] The gluing mechanism includes: a rotating frame, a lid closing frame, a lid closing frame and a gluing device. The gluing mechanism is arranged on both sides of the box transfer mechanism. The rotating frame, the lid closing frame, the lid closing frame and the gluing device are arranged in sequence from the inlet side to the outlet side of the box transfer mechanism. The gluing mechanisms located on both sides of the conveying mechanism are respectively used to seal the box cover plates located at the openings at both ends of the packaging box.

[0052] Furthermore, the gluing mechanisms on both sides of the conveying mechanism are staggered front to back, one of which is close to the entrance of the box transferring mechanism, and the other is close to the exit of the box transferring mechanism, and the gluing mechanism at the entrance works before the gluing mechanism at the exit, so that the gluing mechanism at the entrance first closes and seals the box cover on one side of the packaging box, and then the other gluing mechanism closes and seals the box cover on the other side of the packaging box.

[0053] Specifically, the rotating frame includes rotating frame 1 5 and rotating frame 2 17, and the structures of the two are exactly the same, both of which include: a rotating shaft, a frame plate and a motor. The rotating shaft is rotatably mounted on the supports located on both sides of the box transfer mechanism, and the motor is installed at the bottom of the support and connected to the corresponding rotating shaft; the frame plate is installed on the top of the rotating shaft.

[0054] The cover closing frame includes a cover closing frame 1 6 and a cover closing frame 2 18, and the structures of the two are exactly the same, both of which include: a bracket and an arc-shaped pressure plate, the bracket is fixedly mounted on the top of the support 29, the arc-shaped pressure plate is fixed on the bracket, and the arc-shaped pressure plate is arranged parallel to the conveying direction. When the packaging box enters the box transfer mechanism, the box cover plate on one side of the horizontally opened box cover plate that first enters the box transfer mechanism is closed under the action of the arc-shaped pressure plate, and the other box cover plate is driven by the motor to rotate the shaft and the frame plate, and is closed under the push of the frame plate, thereby closing the two box cover plates in the horizontal direction of the packaging box.

[0055] The cover-closing frame includes a cover-closing frame 1 7 and a cover-closing frame 2 19, both of which have the same structure and are composed of two vertically symmetrical triangular plates. The distance between the two triangular plates gradually decreases from the exit to the entrance of the box-transferring mechanism. The cover-closing frame can also be composed of rods with the same opening and closing angles. The two box covers of the vertical switch of the box enter from the side with the larger opening distance. The opening becomes smaller during the movement, so the box covers of the two vertical switches are closed.

[0056] After the box cover is closed, it is glued and packaged by a glue applicator, which includes a glue applicator 8 and a glue applicator 20, both of which are common glue applicators in the prior art and will not be described in detail here.

[0057] Embodiment 2 of the present invention provides a method for sealing a box for an electric energy meter assembly line, using the box sealing device for an electric energy meter assembly line in embodiment 1, comprising the following steps:

[0058] Fold the empty packaging box and place it in the box storage mechanism, with the two side openings of the packaging box facing the left and right sides of the box storage mechanism respectively;

[0059] The packaging box in the storage mechanism is taken out by the box taking mechanism, and the packaging box is restored from the folded state to the expanded state with the cooperation of the box transfer mechanism, and then the expanded packaging box is sent to the entrance of the box transfer mechanism;

[0060] Push the electric energy meter to be packaged into the packaging box located at the entrance of the box transfer mechanism through the conveying mechanism;

[0061] After the electric energy meter is put into the packaging box, the packaging box is transported to the gluing place of the labeling mechanism through the box transfer mechanism;

[0062] The box cover of the packaging box is closed and sealed with glue through the labeling mechanism.

[0063] The beneficial effect of the present invention is that, compared with the prior art, the present invention sets a box storage mechanism and folds the packaging box horizontally and pre-stores it in the box sealing device, so that when the packaging box enters the box transfer mechanism, the opening direction of the packaging box is parallel to the direction in which the electric energy meter enters the box transfer mechanism, so that the electric energy meter can automatically enter the packaging box under the action of the conveying mechanism without the need for manual placement of the electric energy meter. In addition, the present invention is provided with a box taking mechanism, which uses the box taking mechanism to send the packaging box into the box transfer mechanism, and can automatically convert the packaging box from a folded state to an open state through cooperation with the box transfer mechanism to facilitate the entry of the electric energy meter. Finally, the present invention sets a gluing mechanism, which can close the box cover of the packaging box containing the electric energy meter and perform gluing and box sealing. No manual participation is required in the entire box sealing process of the electric energy meter, and the electric energy meter box sealing operation of a fully automated assembly line can be realized, which greatly improves the packaging efficiency of the electric energy meter and reduces costs.

[0064] In addition, the box-taking mechanism provided in the present invention replaces the manipulator and can grab the packaging box located in the storage mechanism to the box-transferring mechanism. Moreover, the box-taking mechanism has a simple structure, convenient operation, and lower cost than the manipulator, which not only simplifies the box-sealing process of the electric energy meter, but also further saves costs.

[0065] In order to further enable the box storage mechanism to adapt to the storage requirements of packaging boxes of different sizes, the present invention provides a box pressing plate in the box storage mechanism, and the box pressing plate can move in the slide groove at the bottom of the box frame of the box storage mechanism under the drive of the box pressing motor, so as to adjust the storage space size of the box storage mechanism. In addition, after the packaging box is placed in the storage mechanism, the box pressing motor drives the box pressing plate to move, which can automatically press the packaging box and push the packaging box to the exit of the box storage mechanism so that the box taking mechanism can grab the packaging box.

[0066] In addition, in order to further improve the degree of automation of the box sealing device, the present invention is also provided with a plurality of sensors. For example, by providing the first sensor, it is possible to detect whether the conveying mechanism sends the electric energy meter to its outlet, and when the electric energy meter reaches the outlet of the conveying mechanism, the conveying of the conveyor belt is stopped; by providing the second sensor, it is possible to detect that the packaging box moves to the outlet of the box transfer mechanism, and when the packaging box moves to the outlet of the box transfer mechanism, the transmission chain is closed; by providing the third sensor, it is possible to automatically move to press the packaging box when the box pressing plate does not press the packaging box, and can close the box pressing motor when the packaging box reaches the outlet of the box storage mechanism.

[0067] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, ordinary technicians in the relevant field should understand that the specific implementation methods of the present invention can still be modified or replaced by equivalents, and any modifications or equivalent replacements that do not depart from the spirit and scope of the present invention should be covered within the scope of protection of the claims of the present invention.
