[0002] In the production process of the storage battery, various introduction information such as model, specification, size, composition, production date, etc. needs to be engraved on the surface of the shell. The conventional silk screen printing mechanism is usually used to engrave the storage battery shell on the market. When printing, ink is poured into one end of the silk screen printing plate, a certain pressure is applied to the ink part on the silk screen printing plate with a squeegee, and the squeegee is moved towards the other end of the silk screen printing plate at the same time. When the squeegee is scraped across the entire plate, it is lifted and the ink is scraped back to the initial position. Thus, it is a printing stroke. The conventional printing method and the conventional printing equipment have low printing efficiency. In the automatic manufacturing process, the storage battery is usually conveyed and positioned by a conveying belt cooperating with a limiting block. After positioning, silk printing is started. However, during the operation of the machine, various factors may affect the system. Foreign matter (debris, dust, etc.) in the production environment may enter the working area of the conveying belt and the limiting block, which may interfere with the work of the limiting block and cause positioning deviation. The vibration generated during the operation of the machine, whether it is normal operation vibration or abnormal vibration caused by unstable installation or component wear, may affect the position of the limiting block and cause errors. Due to the influence of foreign matter or machine vibration, the limiting block may have errors, and the errors may gradually accumulate.

[0030] Reference Figures 1 to 4 The battery shell silk screen printing machine of the utility model embodiment, it includes: rack 800 is provided with work position 801 and feeding position 802;Silk screen printing mechanism 100 is installed in the work position 801 of rack 800, can print the shell of the storage battery 700 located in the work position 801, silk screen printing mechanism 100 includes silk screen printing plate 110, silk screen printing squeegee 120 and silk screen printing drive mechanism, silk screen printing drive mechanism can drive silk screen printing squeegee 120 away from or close to silk screen printing plate 110, and silk screen printing drive mechanism can drive silk screen printing squeegee 120 to translate on silk screen printing plate 110;Transport assembly 200 is installed in rack 800, can send the storage battery 700 to feeding position 802;Clamping mechanism 300 is installed in rack 800, and clamping mechanism 300 includes clamping hand 310, longitudinal translation mechanism 320 and transverse translation mechanism 330, clamping hand 310 can clamp the storage battery 700, longitudinal translation mechanism 320 can drive clamping hand 310 to move from feeding position 802 to work position 801, and transverse translation mechanism 330 can drive clamping hand 310 to close or away from the storage battery 700;Pushing and positioning mechanism 400 is installed in the work position 801 of rack 800, and pushing and positioning mechanism 400 can fix the storage battery 700 located in the work position 801.
[0031] Firstly, the transport assembly 200 will transport the battery 700 of the previous process to the loading position 802 of the rack 800. Then, under the drive of the longitudinal translation mechanism 320, the clamping hand 310 moves to the loading position 802. Next, the transverse translation mechanism 330 drives the clamping hand 310 to approach the battery 700, and then the clamping hand 310 acts and clamps the battery 700. After that, under the drive of the longitudinal translation mechanism 320, the clamping hand 310 moves to the working position 801, and the clamping hand 310 releases the battery 700. Subsequently, the transverse translation mechanism 430 drives the clamping hand 310 away from the battery 700. At the same time, the push positioning mechanism 400 acts to fix the battery at the working position 801. Next, the silk screen mechanism 100 drives the silk screen squeegee 120 to approach the silk screen plate 110, and drives the silk screen squeegee 120 to move from one end to the other end of the silk screen plate 110, so as to complete the printing of the shell of the battery 700. When the silk screen mechanism 100 prints the shell of the battery 700, the clamping hand 310 will move to the loading position 802 again under the drive of the longitudinal translation mechanism 320. Then, the transverse translation mechanism 330 drives the clamping hand 310 to approach the next battery 700, and the clamping hand 310 acts and clamps the battery 700. Next, under the drive of the longitudinal translation mechanism 320, the clamping hand 310 moves towards the working position 801. At the same time, the silk screen mechanism 100 completes the printing of the previous battery 700. And in the process of moving the clamping hand 310 towards the working position 801, the clamping hand 310 will push the battery 700 at the working position 801 away from the working position 801. Thus, a process cycle is completed, which greatly improves the printing efficiency of the battery 700 and ensures the continuity of the printing.
[0032] In some embodiments, with reference to Figure 3 The silk screen mechanism 100 is provided with two silk screen squeegees 120, which are arranged in a spaced manner.

[0033] Specifically, in some embodiments of the present application, when the silk screen mechanism 100 is printing the battery 700, the two squeegees 120 are alternately close to and away from the screen plate 110. The silk screen driving mechanism first drives one of the squeegees 120 to move towards the screen plate 110 and abut to one end of the screen plate 110. Then, the silk screen driving mechanism simultaneously drives the two squeegees 120 to move towards the other end of the screen plate 110, and when reaching the other end, the printing work for one battery 700 is completed. Then, the other squeegee 120 is switched to close to and abut to the screen plate 110, and the silk screen driving mechanism again simultaneously drives the two squeegees 120 to move towards the initial end of the screen plate 110, and when reaching the initial end, the printing work for one battery 700 is completed again. In summary, the two squeegees 120 reciprocate on the screen plate 110 once to complete the printing work for two batteries 700, thereby greatly improving the efficiency of silk screen printing.

The first driving unit 322 can drive the support plate 321 to move between the feeding position 802 and the working position 801, and the support plate 321 drives the transverse translation mechanism 330 on it to move, and the transverse translation mechanism 330 drives the clamping hand 310 connected thereto to move.
[0035] Specifically, in some embodiments of the present application, the first driving unit 322 is a lead screw transmission mechanism. The lead screw transmission mechanism comprises a screw rod and a sliding block, wherein the sliding block has an internal thread structure matched with the screw rod, and the internal thread structure enables the sliding block to be stably sleeved on the screw rod. When the screw rod starts to rotate, due to the interaction between the threads, the rotary motion of the screw rod is converted into the linear motion of the sliding block, thereby driving the sliding block to move along the screw rod. The sliding block and the support plate 321 are connected, so that the movement of the sliding block further drives the support plate 321 to move, and finally achieves the purpose of driving the support plate 321 to move. The lead screw transmission mechanism has the advantages of simple structure, high transmission precision, etc., and can control the moving position and speed of the support plate 321 more accurately.

In this process, the guide part 411a further positions the position of the storage battery 700, thereby further ensuring the positioning accuracy of the storage battery 700 in the working position 801.
[0048] It is conceivable that, in some embodiments of the utility model, the fourth driving unit 412 can also be an oil cylinder, an electric cylinder or the like, as long as it can meet the requirement of pushing the storage battery 700 to abut against the abutting part 420.
