DETAILED DESCRIPTION

[0037] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer and more understandable, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0038] See also Figures 1 to 5 , is a heat sealing device for lead-acid battery shell packaging as the best embodiment of the utility model, comprising:

[0039] The machine platform 10 has a transmission track 11 therein;

[0040] The limit stop mechanism 12 is arranged on the transmission track 11 in the machine 10, and is used to stop and position the pre-assembled battery shell and battery cover. In this embodiment, the limit stop mechanism 12 is composed of a plurality of cylinders, and the cylinders are extended to achieve stopping and clamping, thereby achieving the positioning stop of the battery shell and the battery cover;

[0041] The translation pressing mechanism 20 includes a frame 21 and a pressing driving device 22 for driving the frame 21 to move in the vertical direction. The middle of the frame 21 is vertically hollowed out to form a working space (not shown in the figure) opposite to the position of the limit stop mechanism 12;

[0042] The heat sealing mold 30 is slidably disposed in the working space inside the frame 21;

[0043] The yield driving device 40 is provided on one side of the frame 21 and is used to drive the heat sealing mold 30 to move back and forth in the working space;

[0044] The lifting cover grabbing mechanism 50 is arranged in the working space and located above the frame 21, and includes a clamping claw assembly 51 for grabbing the battery cover and a cover grabbing driving device 52 for driving the clamping claw assembly 51 to lift;

[0045] When the heat sealing mold 30 moves to the edge position, a clearance area 23 is formed between the inner side thereof and the frame 21 , which is opposite to the position of the limit stop mechanism 12 and through which the clamping jaw assembly 51 can pass.

[0046] In this embodiment, the cap grabbing driving device 52 is a motor-driven device. The motor is fixed on the machine platform 10, and the lifting and lowering drive of the clamping jaw assembly 51 is realized by the motor and the screw, which will not be described in detail here.

[0047] Specifically, Figure 2 , 3 As shown, the frame 21 is surrounded by four side plates 211 to form a square frame. Vertical pressing rails 24 are arranged in the machine platform 10 and at the four corners of the frame 21. The frame 21 is slidably arranged on the pressing rails 24 through pressing sliders. The pressing drive device 22 includes a pressing motor 221 fixed to the inner side of the machine platform 10 and a screw device 222 arranged on the frame 21. The output end of the pressing motor 221 is connected to the screw device 222 through a screw (not shown in the figure). The frame 21 is then driven to rise and fall, so that the pressing motor 221 is fixed to the inner side of the machine table 10, and is connected to the screw device 222 through a screw transmission. When its output shaft works, it drives the screw to rotate, and the screw device 222 driven by the screw thread is driven to move up and down along the pressing guide rails 24 at the four corners, thereby realizing the up and down movement of the entire frame 21, so as to cooperate with the heat sealing mold 30 on the frame 21 to realize the pressing and heating and melting of the upper opening position of the battery shell.

[0048] Preferably, Figure 3 As shown, two opposite side plates 211 are in the shape of a right-angled trapezoid and a lifting end 212 is formed on the same side, a mounting plate 213 is provided between the two lifting ends 212, and a screw device 222 is provided on the mounting plate 213, so that the screw device 222 and the bottom sliding heat sealing mold 30 are installed in a yielding manner through the lifting end 212 and the mounting plate 213, so as to avoid the screw device 222 from encroaching on the moving space of the heat sealing mold 30, so that the heat sealing mold 30 can move smoothly to the corner position of the side plate 211.

[0049] Preferably, Figure 3 , 4As shown, a yield driving motor 41 is fixedly provided on the outer side of one side plate 211, and a driving shaft 42 is rotatably provided between the bottoms of the two opposite side plates 211 through a fixed plate 214. The yield driving motor 41 is connected to the driving shaft 42 through a coupling 411 to drive it to rotate. Driving gears 43 are provided at both ends of the driving shaft 42. A pair of driving racks 44 parallel to each other and meshing with the driving gears 43 are symmetrically provided at the lower end of the heat sealing mold 30. Slide blocks (not shown in the figure) are protruded on both sides of the heat sealing mold 30, and a slide groove 25 that slides with the slide block is formed on the inner side of the side plate 211. In this embodiment, the extension direction of the slide groove 25 is parallel to the extension direction of the driving rack 44. The driving gear 43 and the driving rack 44 are both helical teeth. Therefore, the drive shaft 42 is rotated by the yield driving motor 41, driving the driving rack 44 meshing with it to slide, and finally driving the heat sealing mold 30 to move along the extension direction of the slide groove 25, so as to change the position of the heat sealing mold 30 in the working space.

[0050] Preferably, Figure 5 As shown, a pair of guide portions 251 distributed along the length direction are provided on the inner side of the side plate 211, and the guide portions 251 are in the shape of long strips with a rectangular cross-section. Adjacent guide portions 251 are distributed up and down and a slide groove 25 is formed between the two guide portions 251. The two slide grooves 25 are in relative positions, thereby realizing the limited sliding of the sliders at both ends of the heat sealing mold 30.

[0051] Preferably, Figure 3 , 5 As shown, a travel switch 26 is provided at the end of the slide groove 25, so that the travel switch 26 cooperates with the yield driving motor 41 to sense and limit the limit position of the heat sealing mold 30 at the edge of the slide groove 25, thereby avoiding problems such as dislocation caused by excessive movement of the heat sealing mold 30.

[0052] Preferably, Figure 6 As shown, the side plate 211 is provided with a long strip-shaped positioning groove 27 along the extension direction of the slide groove 25, and a sensing sheet 60 passing through the positioning groove 27 is provided on one side of the heat sealing mold 30. The side plate 211 is provided with a plurality of sensing members 61 that can sense and cooperate with the sensing sheet 60 on the moving path of the sensing sheet 60. In this embodiment, the sensing member 61 is a photoelectric sensor, and the extension direction of the positioning groove 27 is parallel to the moving direction of the heat sealing mold 30. Therefore, the position of the heat sealing mold 30 can be accurately defined by the sensing member 61 in cooperation with the yielding drive motor 41, and the position of the sensing member 61 can be set in cooperation with the yielding position required by the heat sealing mold 30, so as to cooperate with the action of the lifting and grasping cover mechanism 50 to form a yielding area 23 for the clamping jaw assembly 51 to pass through, thereby avoiding interference of the heat sealing mold 30 with the lifting and lowering of the clamping jaw assembly 51.

[0053] Preferably, Figure 3 , 4As shown in Figures 6 and 7, the upper and lower ends of the heat sealing mold 30 respectively form an upper heating end 31 and a lower heating end 32 adapted to the shapes of the battery cover and the battery shell. A plurality of heating devices 33 are provided in the heat sealing mold 30. In this embodiment, two upper heating ends 31 and two lower heating ends 32 of the heat sealing mold 30 are provided, thereby forming a double working mode, and simultaneously performing heat melting on the two battery covers and the battery shell, thereby improving work efficiency.

[0054] Preferably, Figure 7 As shown, the clamping jaw assembly 51 includes a base 511, a positioning cover plate 512 disposed at the bottom of the base 511 and engaged with the battery cover, a clamping jaw cylinder 513 disposed in the base 511, and a pair of movable seats 514 disposed at the output end of the clamping jaw cylinder 513. The two movable seats 514 are disposed on both sides of the positioning cover plate 512 and two clips 515 close to each other are disposed at their ends. The top of the base 511 is connected to the cover grabbing driving device 52. In this embodiment, the positioning cover plate 512 is provided with two to form a heat sealing mold. 30 corresponding to the double working station, the clamping piece 515 is L-shaped, and the two clamping pieces 515 are symmetrically distributed relative to the positioning cover plate 512, so that when the output shafts of the clamping claw cylinder 513 move towards each other, the two movable seats 514 move toward the direction close to the positioning cover plate 512, and when they are attached to the side wall of the base 511, the two L-shaped clamping pieces 515 extend into the coverage range of the positioning cover plate 512, thereby cooperating with the positioning cover plate 512 to form a clamping space for the battery cover, which facilitates the clamping process of the battery cover.

[0055] The working process and beneficial effects of the utility model are as follows:

[0056] First, the pre-assembled battery cover is closed on the upper end of the battery shell, moved along the transmission track 11 into the machine table 10, and stopped under the limit of the limit stop mechanism 12. At this time, the heat sealing mold 30 is in a yielding state, that is, it is located at the edge of the frame 21. At this time, a yielding area 23 for the clamping jaw assembly 51 to pass through is formed in the middle of the frame 21. The cover grabbing drive device 52 drives the clamping jaw assembly 51 to move downward, and the battery cover is limited on the positioning cover plate 512 through the cooperation of the clamping jaw cylinder 513, the moving seat 514 and the clamping piece 515. Then, the cover grabbing drive device 52 drives the clamping jaw assembly 51 to rise again, and the yielding drive motor 41 works. Through the cooperation of the induction member 61 and the induction sheet 60, the heat sealing mold 30 returns to the working position. At this time, the upper heating end 31 and the lower heating end 32 on the heat sealing mold 30 correspond to the lower end of the battery cover and the upper end of the battery shell respectively. The battery cover is moved down to the upper heating end 31 and the heat sealing mold 30 is moved down to the upper end of the battery shell by the pressing motor 221 and the cover grabbing drive device 52. The battery cover and the battery shell are heated synchronously by the heat sealing mold 30 so that the openings to be connected are in a hot-melt state. Finally, the heat sealing mold 30 and the battery cover are raised, and the heat sealing mold 30 is removed again. The battery cover is controlled to be pressed down along the yield area 23 so that the molten battery cover and the connecting part of the battery shell are smoothly connected, completing the heat sealing connection process of the battery cover and the battery shell. The heat-sealed battery cover and the battery shell are transferred to the next process along the transmission track 11 after heat sealing.

[0057] The utility model simplifies the space occupied by the heat sealing mold 30 and the lifting cover grasping mechanism 50 by the translation pressing mechanism 20, so that they can operate stably in the vertical working space, thereby reducing the space occupied by the entire equipment and meeting the requirements of refined production.

[0058] The utility model is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the utility model is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the method concept and technical solution of the utility model, or the concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
