Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.

The existing screen printing equipment is only provided with one printing table and one printing station, and the printing efficiency is low. In view of this, the present invention provides an improved battery plate printing apparatus to improve the printing efficiency of the battery plate.

The battery piece printing device provided by the utility model is described in two embodiments in the following:

first embodiment

As shown in fig. 1 to 3, a battery piece printing apparatus according to a first embodiment of the present invention includes a battery piece input mechanism 10, a printing support mechanism 20, a printing mechanism 30, and a battery piece output mechanism 40, wherein:

the cell input mechanism 10 and the cell output mechanism 40 are arranged on the first axis X, and a cell loading and unloading station is formed between the cell input mechanism 10 and the cell output mechanism 40. And a printing station is arranged on one side of the battery piece feeding and discharging station, and the printing station and the battery piece feeding and discharging station are positioned on a second axis Y vertical to the first axis X.

The printing bearing mechanism 20 comprises a translation mechanism 21, and a first printing table 22 and a second printing table 23 connected to the translation mechanism 21, wherein the translation mechanism 21 is used for driving the first printing table 22 and the second printing table 23 to move along a second axis Y, so that the first printing table 22 and the second printing table 23 are switched between the printing station and the cell loading and unloading station.

A printing mechanism 30 is provided at the printing station.

The cell input mechanism 10 conveys the cell to be printed to the first printing table 22 or the second printing table 23 located at the cell loading and unloading station, the printing mechanism 30 performs printing on the cell to be printed located at the printing station, and the cell output mechanism 40 outputs the printed cell located at the cell loading and unloading station.

It can be seen that the battery piece printing device provided by the embodiment is provided with two movable printing tables. The two printing tables alternately obtain the battery pieces to be printed from the battery piece feeding and discharging station and translate the battery pieces to be printed to the printing station to perform printing operation. Compared with the traditional battery piece printing device, the battery piece printing device has the advantage that the battery piece printing efficiency is remarkably improved.

Optionally, the first printing table 22 is connected to a first driving end of the translation mechanism 21, the second printing table 23 is connected to a second driving end of the translation mechanism 21, and the first driving end and the second driving end respectively and independently drive the first printing table 22 and the second printing table 23 to translate. If optionally, the translation mechanism 21 includes a translation guide rail, a first sliding block, a second sliding block, a first lead screw motor and a second lead screw motor, the first sliding block and the second sliding block are both connected to the translation guide rail in a sliding manner and are respectively connected to the driving rods of the first lead screw motor and the second lead screw motor, the first printing table 22 and the second printing table 23 are respectively installed on the first sliding block and the second sliding block, and the first lead screw motor and the second lead screw motor respectively and independently drive the first sliding block and the second sliding block to translate, so as to drive the first printing table 22 and the second printing table 23 to translate.

In the process of printing, when the first driving end drives the first printing table 22 to move to the battery piece loading and unloading station, the second driving end drives the second printing table 23 to move to the printing station. And when the first driving end drives the first printing table 22 to move to the printing station, the second driving end drives the second printing table 23 to move to the cell loading and unloading station. Namely, when one of the printing tables is translated to the battery piece feeding and discharging station to perform feeding and discharging on the battery pieces, the other printing table carries the battery pieces to be synchronously translated to the printing station to receive printing operation.

Optionally, the first printing table 22 and the second printing table 23 both include a bearing table and a battery piece translation mechanism disposed on the bearing table, the battery piece translation mechanism cooperates with the battery piece output mechanism 10 to output a printed battery piece to the battery piece output mechanism 40, and the battery piece translation mechanism cooperates with the battery piece input mechanism 10 to receive a battery piece to be printed from the battery piece input mechanism 10. That is, the printed battery pieces can be smoothly transferred to the battery piece output structure 40 by the driving of the battery piece translation mechanism, and the battery pieces to be printed inputted from the battery piece input mechanism 10 can be smoothly transferred to the printing table by the driving of the battery piece translation mechanism.

Particularly, the first printing table 22 and the second printing table 23 can continuously complete the blanking and feeding actions by controlling the continuous driving of the cell translation mechanism, so that the working efficiency is further improved. Taking the first printing table 22 as an example, when the first printing table 22 carries the printed battery piece to translate to the feeding station, the battery piece translating mechanism drives the printed battery piece to move toward the battery piece output mechanism 40, and finally outputs the printed battery piece to the battery piece output mechanism 40. The cell translation mechanism remains in a driving state, and thus receives the cell to be printed from the cell input mechanism 10.

Optionally, cell piece translation mechanism includes first running roller, second running roller, stock form and actuating mechanism, wherein: the first roller is arranged at the first end of the bearing table, and the second roller is arranged at the second end, opposite to the first end, of the bearing table. The roll paper is tensioned on the table top of the bearing table, one end of the roll paper is wound on the first roller, and the other end of the roll paper is wound on the second roller.

Taking the first printing table 22 as an example, when the first printing table 22 moves to the battery piece loading and unloading station:

the first roller is close to the cell input mechanism 10, and the second roller is close to the cell output mechanism 40. At the moment, the driving mechanism is controlled to drive the first roller and the second roller to rotate, and the roll paper is wound on the second roller after being discharged by the first roller. In the process, the printed battery plate carried on the bearing table is driven by the roll paper to be output to the battery plate output mechanism 40, and the battery plate to be printed input from the battery plate input mechanism 10 is driven by the roll paper to enter the bearing table. After the blanking and feeding operations are finished, the paper rolling section tensioned on the bearing table is rolled onto the second roller wheel.

Or the second roller is close to the cell input mechanism 10, the first roller is close to the cell output mechanism 40, the driving mechanism drives the first roller and the second roller to rotate so as to drive the roll paper to be discharged through the second roller and then to be wound onto the first roller, so that the printed cell carried on the bearing table is output to the cell output mechanism 40, and the cell to be printed is received from the cell input mechanism 10. In the process, the printed battery plate carried on the bearing table is driven by the roll paper to be output to the battery plate output mechanism 40, and the battery plate to be printed input from the battery plate input mechanism 10 is driven by the roll paper to enter the bearing table. After the blanking and feeding operations are completed, the paper rolling section tensioned on the bearing table is rolled to the first roller wheel.

Optionally, the mesa of plummer is provided with the absorption hole, and the absorption hole sees through the stock form absorption and bears the battery piece on the plummer to the realization is fixed a position the absorption of battery piece, prevents the battery piece landing.

Because the first printing table 22 and the second printing table 23 are arranged in the embodiment, the first printing table 22 and the second printing table 23 alternately move back and forth between the loading and unloading station and the printing station, and the bearing tables of the first printing table 22 and the second printing table 23 are easy to collide in the moving process. In addition, as is well known to those skilled in the art, in order to ensure the printing accuracy of the grid lines, the horizontal angle adjustment of the battery piece needs to be performed before the battery piece is printed.

In order to solve these problems, optionally, the first printing table 22 and the second printing table 23 further include an elevating mechanism and a rotating mechanism, the elevating mechanism is connected to the driving end of the translation mechanism, the rotating mechanism is connected to the driving end of the elevating mechanism, and the bearing table is connected to the driving end of the rotating mechanism. The lifting mechanism is used for driving the bearing platform to lift, and the rotating mechanism is used for driving the bearing platform to rotate in the horizontal direction.

Through the lifting control of the respective lifting mechanisms, the bearing tables of the first printing table 22 and the second printing table 23 can be adjusted to different heights, so that the bearing tables of the first printing table 22 and the second printing table 23 can be avoided in the moving process. Of course, the height adjustment of the battery piece to be printed borne on the bearing table can be realized through the lifting control of the lifting mechanism, so that the battery piece to be printed can be sufficiently close to the printing screen plate of the printing mechanism.

And the rotation control of the respective rotating mechanisms can realize the angle adjustment of the battery pieces to be printed on the bearing tables of the first printing table 22 and the second printing table 23.

Optionally, the loading and unloading station is located at a first height, the printing station is located at a second height, and the second height is higher than the first height. After the bearing table receives the battery piece to be printed from the battery piece input mechanism, the bearing table moves to the position below the printing station under the driving of the translation mechanism and rises to a second height to reach the printing station under the driving of the lifting mechanism.

After the battery piece on the bearing table is printed by the printing mechanism, the bearing table is driven by the lifting mechanism to descend from the second height to the third height, is driven by the translation mechanism to move to the position below the feeding and discharging station, and is driven by the lifting mechanism to ascend from the third height to the first height so as to reach the feeding and discharging station.

So set up, when the plummer of first printing platform 22 was from unloading station towards the printing station translation on first height, the plummer of second printing platform 23 was from the unloading station translation of unloading on the third height from the printing station orientation, and vice versa, so, can guarantee that the plummer of first printing platform, the plummer of second printing platform realize dodging each other at the removal in-process, prevent to produce unexpected collision.

In addition, the plummer removes to the below of printing station earlier, then rises to printing station department under elevating system's drive, then has realized printing mechanism and has dodged the plummer, prevents that printing mechanism and plummer accidental collision.

As described above, after the battery sheet translation mechanism of the first printing table 22 and the battery sheet translation mechanism of the second printing table 23 complete the blanking and loading operations of the roll, the roll paper section originally tensioned on the bearing table is wound onto the first roll or the second roll close to the battery sheet output mechanism 40.

As known to those skilled in the art, since the cost of the roll paper is high, if the degree of contamination of the roll paper segment wound up after the previous blanking and loading operation is low, it is necessary to pay out the roll paper segment again during the subsequent blanking and loading operation to recycle the roll paper segment.

In view of this, it is optional to detect whether the degree of contamination of the roll paper tensioned on the printing table is lower than a predetermined value after the battery sheet on the bearing table is printed by the printing mechanism. When the pollution degree of the roll paper tensioned on the printing table is lower than a preset value, the roll paper can be continuously recycled, and at the moment, the rotating mechanism is configured to drive the bearing table to rotate 180 degrees so as to realize position switching of the first roller and the second roller, so that the rolled roll paper of the previous roll is discharged again when the roll paper of the previous roll is subjected to blanking and loading operations of the next roll.

When the pollution degree of the roll paper tensioned on the printing platform reaches a preset value, the roll paper can not be used any more, and the rotating mechanism does not execute 180 degrees rotation on the bearing platform.

Taking the first printing station 22 as an example:

the first printing table 22 carries the printed battery piece to move to the upper and lower material stations, and it is assumed that the first roller is close to the battery piece input mechanism 10 and the second roller is close to the battery piece output mechanism 40, that is, the first roller is a paper releasing roller and the second roller is a paper collecting roller.

Whether the pollution degree of the roll paper section tensioned on the bearing platform at present is lower than a preset value is detected.

Starting a previous round of blanking and feeding: the driving mechanism is controlled to drive the first roller and the second roller to rotate, so that the roll paper section tensioned on the bearing table is wound on the second roller, and the new roll paper section discharged by the first roller is tensioned on the bearing table.

The first printing table 22 carries the acquired battery piece to be printed to move to the printing station, and the printing mechanism prints the battery piece to be printed. After the printing is completed, the first printing table 22 carries the printed battery piece to translate (return) towards the upper and lower material loading tools again, and particularly, in the return process, the rotating mechanism needs to select whether to execute a 180-degree bearing table of the bearing table according to the pollution degree of the paper winding section (at this time, the paper winding section is wound on the second roller) supported on the bearing table before the previous round of blanking and loading.

If the pollution degree of the paper roll section supported on the plummer before the previous round of unloading, material loading is less than the predetermined value, then, rotary mechanism drive plummer is rotatory 180, so, when first printing platform 22 got back to last unloading station, the second roller is close to battery piece input mechanism 10, first roller then is close to battery piece output mechanism 40, this moment promptly, the second roller switches into the paper roll of putting (notice, at this moment, the outmost stock form is the used paper roll section of previous round, unloading, material loading in-process rolling on the second roller), first roller then switches into the paper roll of receiving.

Starting the next round of blanking and feeding: the driving mechanism is controlled to drive the first roller and the second roller to rotate, so that the roll paper section tensioned on the bearing table is wound on the first roller, and the roll paper section (namely the used roll paper section wound in the previous round, the blanking process and the feeding process) discharged by the second roller is tensioned on the bearing table again. Thus, the recycling of the roll paper is realized.

However, if the degree of contamination of the roll paper supported on the support table before the previous blanking and loading reaches a predetermined value, the rotation mechanism does not perform the rotation of the support table during the return stroke of the first printing table 22. Therefore, the used roll paper of the previous blanking and feeding can not be reused.

Optionally, the battery piece printing apparatus in this embodiment further includes a first detection mechanism 50 disposed above the loading and unloading station, where the first detection mechanism 50 is configured to detect position information of a battery piece to be printed at the loading and unloading station of the battery piece and a degree of contamination of a roll paper tensioned on the printing table.

Through setting up first detection mechanism 50, realized treating the detection of the positional information of printing the battery piece on the one hand, first printing platform 22, second printing platform 23 are in the in-process that will treat that the printing battery piece removes to the printing station, can implement the position and the horizontal angle adjustment of treating the printing battery piece based on this positional information, thereby guarantee to treat that the printing battery piece can accept the printing operation after arriving the printing station, on the other hand, first detection mechanism has realized the detection to the pollution degree of stock form, first printing platform 22, second printing platform 23 can be based on pollution degree testing result when the return stroke, whether the selection implements 180 rotations to the plummer.

Optionally, the battery printing apparatus in this embodiment further includes a second detection mechanism disposed above the battery output mechanism 40, where the second detection mechanism is configured to detect whether the printed battery on the battery output mechanism 40 is qualified.

With continued reference to fig. 1-3, in the present embodiment, the printing mechanism includes a mounting bracket 31, a squeegee drive mechanism, a printing screen 32, and a squeegee assembly 33, wherein: a mounting bracket 31 is provided at an end of the translation mechanism 21 adjacent the printing station and located on the second axis Y, and the printing screen 3 is connected to the mounting bracket 31 and located at the printing station. The squeegee drive mechanism is mounted on the mounting frame 11 and positioned above the printing screen 32, and the squeegee assembly 33 is connected to a drive end of the squeegee drive mechanism and contacts the printing screen 32, and the squeegee drive mechanism drives the squeegee assembly 33 along the first axis X to coat the printing material on the printing screen.

As shown in fig. 4, the mounting bracket 31 may be disposed at the side of the translation mechanism 21 in consideration of the spatial layout of the device, and thus the structure of the battery piece printing device may be more compact.
