Description

Technical Field

[0001] The invention relates to the field of ultrasonic welding, printing and pasting glue for electric cores, and in particular to a mechanism for pasting Z-shaped blue glue at double working stations. Background Art

[0002] In the middle process of square shell power battery, it is necessary to carry out glue insulation treatment on the weld mark after ultrasonic welding of adapter and pole ear. A group of battery cells is composed of A / B battery cells placed in mirror image. Each battery cell has copper and aluminum pole ears and is located on the same side of the battery cell. The blue glue needs to cover the weld mark and extend all the way to the shoulder of the battery cell to form a "Z"-shaped blue glue. A group of battery cells needs to be pasted with four pieces of blue glue. At present, the double-station method of pasting Z-shaped blue glue is to absorb eight pieces of blue glue at the same time through two sets of pasting heads. Due to the size of the pasting head, two pieces of blue glue need to be pasted first, and then move a certain distance to paste two pieces of blue glue at the pole ear of another battery cell. The two sets of pasting heads have the same action and can only be taken again after pasting. Due to the different specifications and dimensions of battery cell products such as thickness, when changing the product line, it is necessary not only to replace the glue suction head and adjust the position of the glue suction head, but also to change the blue glue model, change the size of the glue pulling jaws, adjust the stroke of the glue cutting blade, adjust the width limit of the glue release wheel group, change the program software, etc. The operation is cumbersome and affects the production efficiency to a certain extent.

[0003] In view of this situation, the present invention has newly designed a double-station Z-shaped blue glue sticking mechanism, which allows the left component to be glued while the right component can be glued at the same time, and when the thickness of the battery product is changed, the change can be completed by mechanical operations such as replacing the glue suction head, adjusting the blue glue suction length and limiting the glue suction head, which effectively improves production efficiency and saves changeover costs. Summary of the invention

[0004] The purpose of the present invention is to provide a double-station mechanism for affixing Z-shaped blue glue, which enables the left component to be glued while the right component can be glued at the same time, thereby completing the blue glue affixing action of the same two groups of battery cells, which can save about 2 seconds; and when changing the thickness size of the battery cell product, there is no need to replace the blue glue, change the program, and other operations. The change of model can be completed by mechanical operations such as replacing the glue suction head, adjusting the blue glue suction length and the glue suction head limit, thereby improving production efficiency and saving the cost of change of model.

Specifically, it also includes a plurality of over-the-line drag chains 120, which are used for laying various types of high-flexible cables, vacuum pipelines and gas lines.

[0033] Specifically, the left square bracket 130 and the right square bracket 170 have the same structure and are symmetrically arranged. A single square bracket includes two columns, two bottom plates and a top plate. The bottom of the column is fixedly connected to the bottom plate. The four corners of the bottom plate are provided with connecting holes. When assembled, it can be connected to the corresponding platform by bolts to complete the function of fixed support.

[0034] Specifically, Figure 4 As shown, the left three-axis servo motion assembly 110 and the right three-axis servo motion assembly 150 have the same structure. A single three-axis servo motion assembly includes a long linear module 111 (X direction), a short linear module 112 (Y direction) and a vertical linear module 113 (Z direction). The long linear module is arranged in the same direction as the top plate and connected together. The short linear module is arranged vertically with the long linear module and connected to the moving end of the long linear module. The vertical linear module is placed vertically and connected to the moving end of the short linear module. The left glue assembly 140 and the right glue assembly 160 are installed on the moving end of the vertical linear module; the left glue assembly 140 includes two groups and are respectively named as the left glue assembly No. 2 240 and the left glue assembly No. 3 260, and the right glue assembly 160 includes two groups and are respectively named as the right glue assembly No. 1 280 and the right glue assembly No. 4 290; the left glue assembly 140 and the right glue assembly 160 are connected to the moving end of the vertical linear module 113 through the longitudinal adapter plate 275. Specifically, through the design of the three-axis servo motion assembly, the long-distance position adjustment of the entire glue assembly in the horizontal direction X axis and Y axis and the height adjustment of the vertical direction Z axis are realized, and the blue glue adsorption, movement and glue operation are completed, that is, the conversion between workstations is mainly completed.

[0035] Specifically, Figure 2-4 As shown, the left glue assembly 140 and the right glue assembly 160 have the same structure and are symmetrically distributed. A single glue assembly includes a glue head assembly bottom plate 270, a long guide plate assembly, a short guide plate assembly and a glue head assembly. The long guide plate assembly is staggered in the length direction of the glue head assembly bottom plate 270. The glue head assemblies are grouped in pairs and are movably connected to the output end of the long guide plate assembly through the short guide plate assembly, and the moving direction of the short guide plate assembly is perpendicular to the moving direction of the long guide plate assembly. Specifically, the glue head assembly bottom plate 270 is connected to the moving end of the vertical linear module 113 through a longitudinal adapter plate 275, and is driven by the vertical linear module 113 to achieve rising and falling movements.

[0036] like Figure 2 As shown, two groups of long guide plate assemblies on each side are arranged in a staggered distribution, and each group of the long guide plate assemblies includes a long offset cylinder assembly 250 for glue application, a long guide rail 274 and a long offset sliding plate 273. The long offset cylinder assembly 250 for glue application is installed on both sides of the length direction of the bottom plate 270 of the glue application head assembly and is staggered. The two long guide rails 274 are staggeredly connected to the bottom large plane of the bottom plate 270 of the glue application head assembly, and the long offset sliding plate 273 is slidably connected to the bottom large plane of the bottom plate 270 of the glue application head assembly. On the long guide rail 274; a long misalignment limit assembly 271 is provided on one side of the long guide rail 274, the limit end of the long misalignment limit assembly 271 is aligned with and abuts against the long misalignment sliding plate 273 for limit, and a cylinder joint adapter plate 272 is connected to the side wall of the long misalignment sliding plate 273, and the telescopic rod of the rubber-coated long misalignment cylinder assembly 250 is positioned and connected to the bottom of the cylinder joint adapter plate 272 and drives the cylinder joint adapter plate 272 to slide linearly. Specifically, the limit switch assembly 271 includes a mounting bracket and a buffer. The mounting bracket is connected to the glue assembly adapter plate 270 by screws and is located at one end of the long guide rail 274. The buffer is connected to the upper part of the mounting bracket, and the working end of the buffer is aligned with the vertical side wall of the long offset sliding plate 273 and realizes the limit operation through contact; the cylinder joint adapter plate 272 is designed as a T-shaped connector, one end of the T-shaped connector is fixed to the outer wall of the long offset sliding plate 273 by screws, and the top of the T-shaped connector is connected to the cylinder floating joint in the glue long offset cylinder assembly 250. When the cylinder floating joint is extended, the long offset action can be realized through the connection of the cylinder joint adapter plate 272, that is, the two groups of glue heads can move in the left and right directions respectively, and then adjust the size of the distance between each other.

[0037] Among them, the long offset glue sticking cylinder assembly 250 includes a cylinder, a floating joint and a cylinder mounting part, and the cylinder is fixedly mounted on the side of the glue sticking head assembly bottom plate 270 through the cylinder mounting part; during implementation, the cylinder does not move when the glue sticking head changes distance, and the central cylinder piston rod extends out. Because the floating joint and the cylinder joint adapter plate 272 are connected, the cylinder joint adapter plate 272 also moves synchronously, and then drives the long offset sliding plate 273 to move linearly along the long guide rail 274. At this point, a group of glue sticking heads in the long offset have moved to the right, and the glue sticking heads on the other side have moved to the left. The cylinders are all electrically connected to the PLC controller. According to the setting of the program, the two can choose to move synchronously or sequentially. The movement mode is controlled by a computer program to achieve automatic adjustment, which is more time-saving and labor-saving.

[0038] like Figure 3 As shown, the short guide plate assembly includes a rubber-sticking short offset cylinder assembly 220, an adjustment base plate 230 and a short guide rail 231. The adjustment base plate 230 is movably connected to the rubber-sticking head assembly base plate 270 through the short guide rail 231. The outer end of the adjustment base plate 230 is provided with an L-shaped avoidance groove. The rubber-sticking short offset cylinder assembly 220 is located in the L-shaped avoidance groove and is fixedly mounted on the large plane of the rubber-sticking head assembly base plate 270; the telescopic rod end of the rubber-sticking short offset cylinder assembly 220 abuts against a side wall of the L-shaped avoidance groove.

[0039] Specifically, a limiting assembly is provided at a position close to the center of the adjusting base plate 230, and the limiting assembly includes a fixed limiting piece 232 and a short misalignment limiting assembly 233. The bottom end of the fixed limiting piece 232 is fixedly connected to the base plate 270 of the glue head assembly, and the top end of the fixed limiting piece 232 passes through the U-shaped groove on the adjusting base plate 230. The short misalignment limiting assembly 233 is positioned and connected to the adjusting base plate 230, and the horizontal limiting screw on the short misalignment limiting assembly 233 cooperates with the top side wall of the fixed limiting piece 232. A short misalignment limiting assembly 236 is provided at a side edge of the adjusting base plate 230 away from the glue short misalignment cylinder assembly 220. The short misalignment limiting assembly 236 includes a limiting block and a side limiting screw assembly that cooperate with each other. The limiting block is positioned and connected to the side edge of the adjusting base plate 230, and the side limiting screw assembly is connected to the base plate 270 of the glue head assembly.

[0040] During implementation, the short offset cylinder assembly 220 receives the start command from the PLC controller, the telescopic rod extends and pushes the adjustment base plate 230 to move in a straight line along the short guide rail 231, and stops after reaching the specified position; when it retracts in the reverse direction, it drives the adjustment base plate 230 to retreat. During the movement, the position is limited by the short offset limit assembly 1 233, the fixed limit piece 232 and the short offset limit assembly 2 236.

[0041] During implementation, the position of the glue suction head can be adjusted bidirectionally through the long guide plate assembly and the short guide plate assembly to be suitable for glue sticking operations of battery cells of more specifications.

[0042] The glue head assembly includes a fixed side glue head 190 and a floating side glue head 200 arranged side by side, the fixed end of the fixed side glue head 190 is directly connected to the fixed seat 235, the fixed end of the floating side glue head 200 is connected to the fixed seat 235 through a floating spring structure 210, and the fixed seat 235 is connected to the adjustment base plate 230 through a glue head position adjustment seat 234; the sides of the fixed side glue head 190 and the floating side glue head 200 are each connected to a vacuum glue suction pipeline joint 180, and the vacuum glue suction pipeline joint 180 is connected to a vacuum pump for power supply through a pipeline. Specifically, the positions of the fixed side glue head 190 and the floating side glue head 200 correspond to the glue sticking positions of the battery cells.

[0043] Specifically, the bottom surface of the adjustment base plate 230 close to the glue application head assembly is provided with scale lines to facilitate comparison during position adjustment and achieve precise adjustment.

[0044] The connecting through hole provided on the rubber head position adjustment seat 234 is set to be waist-shaped, and the installation position of the rubber head position adjustment seat 234 is placed with reference to the scale line and is locked and fixed by fastening bolts. The shape of the connecting through hole facilitates the adjustment of the position of the fixing bolt, and the assembly is more convenient and quick, and cooperates with the scale line to ensure the convenience of installation and the accuracy of the position.

[0045] It also includes a PLC controller. Multiple driving components on the left three-axis servo motion assembly 110 and the right three-axis servo motion assembly 150, the cylinders of the long offset glue cylinder assembly 250 and the short offset glue cylinder assembly 220, and the solenoid valves on the fixed side glue head 190 and the floating side glue head 200 are all electrically connected to the PLC controller to achieve automatic control. The position adjustment, adsorption and pasting of blue glue are all automated, saving time and effort.

[0046] The use process of the present invention is as follows:

[0047] First, the left three-axis servo motion assembly 110 and the right three-axis servo motion assembly 150 in the present invention are fixedly supported by the left square bracket 130 and the right square bracket 170, and the left glue assembly 140 and the right glue assembly 160 are installed, and the glue is precisely positioned during implementation; a plurality of line drag chains 120 are arranged on the top of the bracket for laying out various types of highly flexible cables, vacuum pipelines and gas lines;

[0048] In the glue taking operation, the fixed side glue head 190 and the floating side glue head 200 are each equipped with a vacuum glue suction pipeline joint 180. Under the action of the vacuum glue suction pipeline joint 180, the fixed side glue head 190 and the floating side glue head 200 work together to generate an adsorption force to absorb a piece of blue glue;

[0049] During the gluing operation, a total of eight pieces of blue glue are adsorbed on the left glue assembly 240, the left glue assembly 360, the right glue assembly 180 and the right glue assembly 4 290 under the action of vacuum; the two groups of battery cells are composed of battery cell group 1 (including single battery cell 1 & single battery cell 2) and battery cell group 2 (including single battery cell 3 & single battery cell 4), and the two groups of battery cells are arranged left and right; the left glue assembly 240 and the left glue assembly 3 260 complete the gluing action on the single battery cell 2 and the three tabs of the single battery cell, that is, each group of battery cells is glued half, and the remaining half is performed by the right glue assembly 1 and the right glue assembly 4 290, completing the gluing action on the single battery cell 1 and the four tabs of the single battery cell;

[0050] The adjustment operation during gluing takes the left No. 2 glue assembly 240 as an example: first, the long offset gluing cylinder assembly 250 is started to complete the adjustment of the long side distance of the left No. 2 glue assembly 240, and the cylinder stroke limit is determined according to the spacing between the two groups of battery cells during the adjustment; then, the short offset gluing cylinder assembly 220 is started to complete the adjustment of the short side distance of the left No. 2 glue assembly 240, and the cylinder stroke limit is determined according to the spacing between the single batteries in the battery cell group; the other three sets of gluing assemblies have the same action;

[0051] Further, after the left three-axis servo motion component 110 reaches the gluing position, the component descends, and the left glue component No. 2 240 and the left glue component No. 3 260 carry the blue glue to attach to the single battery cell 2 and the single battery cell 3; wherein, the floating side glue head 200 first attaches to the shoulder of the battery cell, and under the action of the floating spring structure 210, the floating side glue head 200 can remain stationary, and the left three-axis servo motion component 110 continues to descend until the fixed side glue head 190 is attached to the tab of the single battery cell 2;

[0052] The other workstations perform the same gluing operations, and the double-workstation Z-shaped blue glue affixing operation is now completed.

[0053] Specifically, Figure 5 As shown, part of the glue sticking position is located on the pole ear of the battery cell 300, and part of it is located on the body of the battery cell 300. The two parts are transitioned through the vertical part, and a Z-shaped blue glue shape is formed after pasting; the fixed side glue sticking head 190 is directly above the pole ear, and the floating side glue sticking head 200 is located above the shell of the battery cell; the equipment can simultaneously realize the glue sticking operation of four groups of eight battery cells in total.

[0054] In the present invention, the glue head components are symmetrically or staggeredly distributed and have strong interchangeability, so that the left component can be glued while the right component can be glued at the same time, and the blue glue attaching action of the same two groups of battery cells can be completed in about 2 seconds; and when the thickness size of the battery cell product is changed, there is no need to replace the blue glue, change the program, and other operations. The change of model can be completed by replacing the glue suction head, adjusting the blue glue suction length and the limit of the glue suction head, and other mechanical operations, thereby improving production efficiency and saving change of model costs.
