Technical Field

[0001] This invention belongs to the field of battery manufacturing technology, specifically relating to a device for detecting the matching of lead paste quantitative application and grid thickness. Background Technology

[0002] In the manufacturing process of lead-acid batteries, the application of lead paste to the grid is a crucial step. The uniformity and accuracy of the lead paste application directly affect the final battery's capacity, consistency, and lifespan. Currently, the industry widely uses automated paste application machines for the grids, such as belt-type double-sided paste application machines.

[0003] However, in actual production applications, existing coating equipment and testing methods have the following shortcomings: Currently, determining whether the lead paste layer thickness of the coated grid matches the process requirements relies heavily on manual sampling or offline measurement. This method is inefficient and cannot achieve full inspection or rapid online testing of the coated product, making it difficult to monitor the coating quality. Therefore, this application proposes a device for detecting the matching of quantitative lead paste coating with grid thickness. Summary of the Invention

[0004] The purpose of this invention is to provide a device for detecting the matching of lead paste quantitative application and grid thickness, so as to solve the problem mentioned in the background art that the thickness of the lead paste layer of the grid after coating is matched with the process requirements, which currently mostly relies on manual sampling or offline measurement.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a device for detecting the matching of quantitative lead paste application and grid thickness, comprising an operating table, a coating rack, and a lead paste application mechanism, wherein the coating rack is used to store the grid body; The operating table is equipped with a coating platform, and the lead paste coating mechanism is installed on the coating platform. The operating table is equipped with a grid transverse feeding mechanism connected to the coating rack. The grid transverse feeding mechanism is used to move the coating rack to the position of the lead paste coating mechanism or to the position of the grid longitudinal feeding mechanism. The operating platform is equipped with a grating longitudinal feeding mechanism, a lifting unit connected to the grating longitudinal feeding mechanism, a lifting frame connected to the lifting unit, a suction cup mounted on the lifting frame, and a testing platform. The suction cup is used to hold or release the grating body, and the grating longitudinal feeding mechanism is used to move the grating body held by the suction cup to the testing platform.

The pressure block is inserted into the sliding groove and slides with the sliding groove. The top of the pressure block is provided with a first inclined surface. When the grid body is fully inserted into the storage groove, the lower end face of the pressure block is located above the grid body.

[0008] Preferably, a spring is provided in the slide groove, with one end of the spring connected to the positioning box and the other end of the spring connected to the pressure block. The spring is used to give the pressure block a force to move away from the slide groove.

[0009] Preferably, the positioning box and the coating rack are provided with vertical grooves, which are perpendicular to the sliding grooves.

[0010] Preferably, the plate grid transverse feeding mechanism includes a threaded slider, a feeding box with a transverse feeding groove that slides with the threaded slider, a feeding screw inserted into the feeding box and threadedly connected to the threaded slider, a feeding drive motor mounted on the feeding box and connected to the feeding screw, and a coating rack mounted on the threaded slider.

[0015] Beneficial effects: This invention provides a device for detecting the quantitative application of lead paste and the matching of grid thickness. The device involves moving the coating rack to the position of the lead paste application mechanism, aligning the grid body on the coating rack with the lead paste application mechanism, and activating the lead paste application mechanism to evenly apply lead paste onto the grid body. When the coating rack is moved to the position of the grid longitudinal feeding mechanism, the lifting unit drives the lifting rack to move downwards. The suction cup and positioning block on the lifting rack move downwards, and when the second inclined surface on the positioning block abuts against the first inclined surface on the pressure block, the positioning block continues to move downwards, squeezing the pressure block and causing it to retract into the chute. The positioning block and the grid body are offset laterally, meaning the positioning block is not obstructed by the grid body during its downward movement. The positioning block and suction cup continue to move downwards until the suction cup reaches the grid body, activating the suction cup to hold the grid body. Afterwards, the grid body, suction cup, and positioning block move upwards without being obstructed by the pressure block, thus allowing the grid body to be removed from the storage frame. The lifting unit then moves the grid body upwards, activates the grid longitudinal feed mechanism to move it to the position of the inspection table, and performs the lead paste thickness test on the grid body on the inspection table, which can monitor the coating quality.

[0018] The specific embodiments of the present invention will be described in detail below, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0019] like Figures 1-7 As shown in the figure, the present invention provides a lead paste quantitative application and grid thickness matching detection device, including an operating table 1, a coating rack 2, and a lead paste application mechanism 9. The coating rack 2 is used to store the grid body 3. The lead paste application mechanism 9 can uniformly apply lead paste to the grid body 3. It can be a DCM-360 belt double-sided paste applicator. The coating rack 2 is moved to the position of the lead paste application mechanism 9. At this time, the grid body 3 on the coating rack 2 is aligned with the lead paste application mechanism 9. The lead paste application mechanism 9 is turned on so that it can uniformly apply lead paste to the grid body 3.

[0020] In order to store the grid body 3, a storage frame 4 is provided on the coating rack 2. The storage frame 4 is provided with a storage groove that fits with the outer wall of the grid body 3. A pressure block 5 and a positioning box 6 installed on the coating rack 2 are provided at the storage frame 4. A sliding groove is provided in the positioning box 6. The pressure block 5 is inserted into the sliding groove and slides with the sliding groove. A first inclined surface is provided on the top of the pressure block 5. When the grid body 3 is fully inserted into the storage groove, the lower end face of the pressure block 5 is above the grid body 3.

[0021] Specifically, a spring 7 is installed inside the slide groove. One end of the spring 7 is connected to the positioning box 6, and the other end of the spring 7 is connected to the pressure block 5. The spring 7 is used to give the pressure block 5 a force to move away from the slide groove. Under the elastic force given by the spring 7, the pressure block 5 can move above the grid body 3. The grid body 3 and the storage groove are connected vertically. The pressure block 5 presses down on the grid body 3 so that it cannot be moved out of the storage groove. In this way, the position of the grid body 3 can be locked. After the position of the grid body 3 is locked, there will be no positional change when applying lead paste, which facilitates the application of lead paste.

[0022] It should be noted that the positioning box 6 and the coating rack 2 are provided with vertical grooves 8, which are distributed perpendicularly to the slide grooves.

[0023] Specifically, the operating table 1 is equipped with a coating platform 10, and the lead paste coating mechanism 9 is installed on the coating platform 10. A longitudinal feeding mechanism can also be set at the coating platform 10. The structure is the same as the transverse feeding mechanism 11 of the grid. Through the threaded cooperation between the lead screw and the slider, the lead paste coating mechanism 9 is driven to perform transverse mechanism, so that it can cover the entire grid body 3. In this way, the coating of lead paste on the grid body 3 can be realized.

[0024] Specifically, the operating table 1 is equipped with a grid transverse feeding mechanism 11 connected to the coating rack 2. The grid transverse feeding mechanism 11 is used to drive the coating rack 2 to move laterally, so that the coating rack 2 can move to the position of the lead paste coating mechanism 9 or to the position of the grid longitudinal feeding mechanism 13.

[0025] Specifically, the plate grid transverse feeding mechanism 11 includes a threaded slider 1101, a feeding box 1102 with a transverse feeding groove that slides and engages with the threaded slider 1101, a feeding screw 1103 inserted into the feeding box 1102 and connected to the threaded slider 1101 by threads, a feeding drive motor 1104 mounted on the feeding box 1102 and connected to the feeding screw 1103, and a coating rack 2 mounted on the threaded slider 1101.

[0026] After the feeding drive motor 1104 is turned on, it can drive the feeding screw 1103 to rotate in both directions. The feeding screw 1103 is connected to the threaded slider 1101 by a thread. At the same time, the feeding box 1102 is provided with a transverse feed groove that slides with the threaded slider 1101. Thus, the forward and reverse rotation of the feeding screw 1103 can drive the coating frame 2 to move laterally. The lead paste coating mechanism 9 and the grid longitudinal feed mechanism 13 are within the stroke range of the grid transverse feed mechanism 11.

[0027] Specifically, a movable frame 12 is provided on the upper side of the operating table 1. The bottom of the movable frame 12 is connected to the plate grid transverse feeding mechanism 11. The coating rack 2 is installed at one end of the movable frame 12. The movable frame 12 includes a first vertical plate, a support frame, and a second vertical plate. The first vertical plate and the second vertical plate are fixedly connected by the support frame. The coating rack 2 is installed on the second vertical plate.

[0028] Specifically, the operating table 1 is equipped with a grid longitudinal feeding mechanism 13, a lifting unit connected to the grid longitudinal feeding mechanism 13, a lifting frame connected to the lifting unit, a suction cup 14 installed on the lifting frame, and a detection table 15. The suction cup 14 is used to hold or release the grid body 3. The grid longitudinal feeding mechanism 13 is used to move the grid body 3 held by the suction cup 14 to the detection table 15. The detection table 15 is used to measure the thickness of the lead paste applied to the grid body 3. The lifting unit can be a cylinder.

[0029] Specifically, the longitudinal feed mechanism 13 of the grid can adopt the same structure as the transverse feed mechanism 11 of the grid, namely, the screw and nut structure.

[0030] The grating body 3 is inserted into the storage frame 4, and there is a pressure block 5 on it to prevent the movement of the grating body 3. In order to remove the pressure block 5 before the suction cup 14 reaches the height of the grating body 3, a positioning block 16 is provided at the lifting frame. A second inclined surface is provided at the lower end of the positioning block 16. The second inclined surface cooperates with the first inclined surface at the top of the pressure block 5. A vertical groove 8 that cooperates with the positioning block 16 is provided in the positioning box 6.

[0031] Move the coating frame 2 to the position of the lead paste coating mechanism 9. At this time, the grid body 3 on the coating frame 2 is aligned with the lead paste coating mechanism 9. Turn on the lead paste coating mechanism 9 so that it can evenly apply lead paste to the grid body 3. When the coating frame 2 is moved to the position of the grid longitudinal feeding mechanism 13, the lifting unit can drive the lifting frame to move downward. The suction cup 14 and the positioning block 16 on the lifting frame move down. When the second inclined surface on the positioning block 16 abuts against the first inclined surface on the pressure block 5, the positioning block 16 continues to move down, which can squeeze the pressure block 5 and make the pressure block 5 retract into the groove. The positioning block 16 and the grid body 3 The left and right directions are staggered, so that the positioning block 16 will not be blocked by the grid body 3 during the downward movement. In this way, the positioning block 16 and the suction cup 14 continue to move downward until the suction cup 14 reaches the grid body 3. The suction cup 14 is activated (the suction cup 14 is connected to the air pump. After the air pump is activated, the air at the suction cup 14 can be sucked away. The suction cup 14 is attached to the grid body 3. After the air is sucked away, the suction cup 14 will generate a suction force to hold the grid body 3 due to the air pressure). The grid body 3 is sucked in. Then, the grid body 3, the suction cup 14, and the positioning block 16 will not be blocked by the pressure block 5 during the upward movement. In this way, the grid body 3 can be taken out from the storage box 4. Then, the lifting unit drives the grid body 3 to continue to move upward, and the grid longitudinal feeding mechanism 13 is activated to move it to the position of the inspection table 15, and the thickness of lead paste on the grid body 3 is detected on the inspection table 15.

[0032] Specifically, the testing table 15 is equipped with a testing frame 17, a first distance testing unit 18 and a second distance testing unit 19 mounted on the testing frame 17. Both the first distance testing unit 18 and the second distance testing unit 19 use laser distance measurement. The first distance testing unit 18 measures the height between itself and the upper surface of the testing table 15, while the second distance testing unit 19 is aligned with the lead paste and used to measure the height between the upper surface of the lead paste and itself. The height difference between the two is the height of the lead paste. This completes the effect of lead paste thickness detection. The thickness detection result is used to determine whether it is within the set value, and thus to determine whether the lead paste application on the grid body 3 meets the requirements.

[0033] In summary, this invention provides a device for detecting the quantitative application of lead paste and the matching of grid thickness. After the feeding drive motor 1104 is turned on, it can drive the feeding screw 1103 to rotate in both directions. The feeding screw 1103 is connected to the threaded slider 1101 by a thread. At the same time, the feeding box 1102 is provided with a transverse feed groove that slides with the threaded slider 1101. Thus, the forward and reverse rotation of the feeding screw 1103 can drive the coating frame 2 to move laterally. The lead paste coating mechanism 9 and the grid longitudinal feed mechanism 13 are within the stroke range of the grid transverse feed mechanism 11.

[0034] Move the coating frame 2 to the position of the lead paste coating mechanism 9. At this time, the grid body 3 on the coating frame 2 is aligned with the lead paste coating mechanism 9. Turn on the lead paste coating mechanism 9 so that it can evenly apply lead paste to the grid body 3. When the coating frame 2 is moved to the position of the grid longitudinal feed mechanism 13, the lifting unit can drive the lifting frame to move downward. The suction cup 14 and the positioning block 16 on the lifting frame move down. When the second inclined surface on the positioning block 16 abuts against the first inclined surface on the pressure block 5, the positioning block 16 continues to move down. The movement of the pressure block 5 allows it to be squeezed and retracted into the groove. The positioning block 16 is offset from the grid body 3 in the left and right directions, meaning that the positioning block 16 will not be blocked by the grid body 3 during its downward movement. Thus, the positioning block 16 and the suction cup 14 continue to move downward until the suction cup 14 reaches the grid body 3, and the suction cup 14 is activated to hold the grid body 3. Afterward, the grid body 3, the suction cup 14, and the positioning block 16 will not be obstructed by the pressure block 5 during their upward movement, thus allowing the grid body 3 to be removed from the storage frame 4. Then, the lifting unit drives the grid body 3 to continue to move upward, and the grid longitudinal feeding mechanism 13 is activated to move it to the position of the inspection table 15, and the thickness of lead paste on the grid body 3 is detected on the inspection table 15.

[0035] The above-disclosed embodiments are merely a few specific examples of the present invention. However, the embodiments of the present invention are not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
