Abstract
Description
Technical Field
[0001] This utility model relates to the field of battery panel grid coating effect testing technology, and in particular to a device for testing the adhesion strength of lead paste on electrode plates. Background Technology
[0002] In the production process of lead-acid battery plates, which includes the grid coating and curing processes, it is necessary to test the strength of the lead paste applied to the plates. The most common method is to release the cured plates horizontally from a specific height and determine whether the plates are qualified by observing the loosening of the lead paste after the plates fall.
[0003] Conventional electrode drop testing devices use a vacuum suction cup to pick up the electrode, suspending it at a specific height. By controlling a manual valve to disconnect the negative pressure air circuit connected to the suction cup, the electrode falls onto the test surface under gravity. However, this method of picking up electrode plates using a vacuum suction cup has limitations in its applicability. As the size and weight of the electrode increase, the specifications and installation structure of the vacuum suction cup must also increase. Furthermore, it is limited by the air source pressure, making it impossible to pick up some heavier electrode plates. Summary of the Invention
[0004] To address the aforementioned problems, this utility model discloses a device for testing the adhesion strength of lead paste on electrode plates. The device includes a main frame, with an electrode plate release device at the upper end of the main frame. The electrode plate release device includes a mounting base plate, and a cylinder connecting plate is fixedly connected to the upper center of the mounting base plate. A pneumatic finger is fixedly connected to the side wall of the cylinder connecting plate. Each of the two grippers of the pneumatic finger is fixedly connected to a reset latch mounting block. The reset latch mounting block has a reset latch and a pin, and the reset latch rotates and engages with the pin at the lower end of the reset latch mounting block. When the pneumatic finger moves, the reset latch mounting block moves closer to or further away from the grippers. Note that one side of the lower end of the reset latch is sloped.
[0005] The mounting base plate has rotating shafts on both sides below it. A support plate and a shaft limiting block are fixedly connected to the side wall of each shaft, with one end of the limiting block resting on the edge of the reset latch. A tension spring is located in the middle of the limiting block. When the pneumatic finger is activated, the two reset latch mounting blocks move towards each other, and the limiting block disengages from the reset latch, causing the support plate to change from a horizontal to a vertical position. Before testing, the support plate needs to be leveled. At this point, the reset latch is in its initial state. When the support plate is manually moved to a horizontal position, the reset latch can rotate around the pin. Rotating the reset latch to a suitable angle allows the support plate to pass over it, and when lowering the support plate, its edge rests against the edge of the reset latch, ensuring the support plate remains level.
[0006] Preferably, a reversing valve is provided at the upper end of the mounting base plate, and a shaft fixing block is rotatably fitted at both ends of the rotating shaft. A spring fixing block is fixedly connected to the lower end of the tension spring. The shaft fixing block and the spring fixing block are fixedly connected to the main frame.
[0007] Preferably, the lower part of the main frame is provided with a material dropping base plate, and a drawer slide groove is provided below the material dropping base plate. A dust collection drawer is slidably fitted onto the drawer slide groove. During testing, the electrode plate falls onto the material dropping base plate. Based on the separation of lead paste, the adhesion strength of the lead paste is judged. Furthermore, the lead paste separated on the material dropping base plate is swept into the dust collection drawer for weighing to determine the adhesion strength of the lead paste.
[0008] Preferably, the main frame includes four vertical columns, with horizontal and vertical beams fixedly connected to the upper and lower parts of each column, forming a cuboid structure. A base plate is fixedly connected to the lower end of each column. The main frame is constructed of angle steel.
[0009] Preferably, the main frame is further covered with a protective baffle, which includes a front panel, a first side panel, a back panel, and a second side panel that surround the side walls of the main frame in sequence. An inspection door is provided below the front panel. This prevents lead paste from spilling into other areas and contaminating the laboratory environment during testing.
[0010] The beneficial effects of this invention are as follows: First, a tension spring is used to act on the support plate, and one side of the support plate is supported on the reset buckle. When the support plate and the reset buckle are separated, the support plate can respond quickly under the pull of the tension spring, which meets the requirements of electrode plate testing. Second, the electrode plate is placed on the support plate, so there are few restrictions on the weight and size of the electrode plate, that is, this device has the advantage of a wide range of applications.

[0021] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only for illustrating the present invention and are not intended to limit the scope of the present invention. It should be noted that the terms "front", "rear", "left", "right", "up" and "down" used in the following description refer to the directions in the accompanying drawings, and the terms "inner" and "outer" refer to the directions toward or away from the geometric center of a specific component, respectively.
[0022] like Figures 1 to 8 As shown, a device for testing the adhesion strength of lead paste on electrodes includes a main frame 10, which is generally rectangular in shape. An electrode release device 20 is provided at the upper end of the main frame 10. The electrode release device 20 includes a mounting base plate 201, which is mounted and fixed to the upper end of the main frame 10. A cylinder connecting plate 203 is fixedly connected to the middle of the upper end of the mounting base plate 201. Pneumatic fingers 202 are fixedly connected to the side wall of the cylinder connecting plate 203. Both grippers of the pneumatic fingers 202 are fixedly connected to a composite... When the pneumatic finger 202 is working, the reset latch mounting block 205 moves closer or further away from the grippers. The reset latch mounting block 205 is equipped with a reset latch 206 and a pin 207. The reset latch 206 rotates and engages with the pin 207 at the lower end of the reset latch mounting block 205, meaning that the reset latch 206 can rotate around the pin 207. At the same time, the lower end of the reset latch 206 is inclined, and the upper end of the reset latch 206 is horizontal only under the action of gravity.
[0023] Rotary shafts 209 are rotatably mounted on both sides of the mounting base plate 201. A support plate 210 and a rotating shaft limiting block 211 are fixedly connected to the side wall of the rotating shaft 209. One end of the rotating shaft limiting block 211 overlaps the edge of the reset buckle 206. At this time, the support plate 210 is in a horizontal state. A tension spring 213 is provided in the middle of the rotating shaft limiting block 211. When the support plate 210 is in a horizontal state, the tension spring 213 stores elastic potential energy. When the pneumatic finger 202 is activated, the two reset buckle mounting blocks 205 move towards each other, and the rotating shaft limiting block 211 disengages from the reset buckle 206, causing the support plate 210 to change from a horizontal state to a vertical state.
[0024] During the test, the support plate 210 is first restored to a horizontal state. Specifically, the support plate 210 is manually moved, during which the tension spring 213 stores elastic potential energy. At the same time, the edge of the support plate 210 abuts against the inclined surface of the lower end of the reset latch 206, causing the reset latch 206 to rotate and eventually pass over the reset latch 206. Then the support plate 210 is released, with its edge resting on the upper edge of the reset latch 206. Next, the test electrode is placed on the support plate 210. Finally, the pneumatic finger 202 is activated, pulling the reset latch mounting block 205 to move in opposite directions. At this time, the support plate 210 and the reset latch 206 are disengaged, and under the action of the tension spring 213, the support plate 210 changes from a horizontal state to a vertical state, and the electrode falls downward without support.
[0025] A reversing valve 204 is provided at the upper end of the mounting base plate 201. The reversing valve 202 controls the position of the reset buckle mounting block 205. Both ends of the rotating shaft 209 are rotatably fitted with rotating shaft fixing blocks 208, which are fixedly connected to the main frame 10. The lower end of the tension spring 213 is fixedly connected to a spring fixing block 212, which is also fixedly connected to the main frame 10.
[0026] The lower part of the main frame 10 is provided with a material dropping base plate 30, which is a square marble slab with a smooth surface. There is a notch at each of the four corners for dust to fall on. The electrode plate falls directly on the material dropping base plate 30. The adhesion strength of the lead paste is judged according to the degree of separation. A drawer slide 105 is provided below the material dropping base plate 30. A dust collection drawer 40 is slidably installed on the drawer slide 105, which can sweep the scattered lead paste into the dust collection drawer 40 for centralized treatment.
[0027] The main frame 10 includes four vertical columns 103. The upper and lower parts of the columns 103 are fixedly connected to crossbeams 101 and longitudinal beams 102. The columns 103, crossbeams 101 and longitudinal beams 102 are all angle steel, and the columns 103, crossbeams 101 and longitudinal beams 102 form a cuboid structure. The lower end of the columns 103 is fixedly connected to a base cup 104. The base cup 104 has external threads and is locked and fixed to the bottom of the column 103, which has a square plate with threaded holes welded to the bottom surface, by a nut.
[0028] The main frame 10 is also covered with a protective baffle 50, which includes a front plate 501, a first side plate 502, a back plate 504, and a second side plate 503 arranged sequentially around the side wall of the main frame 10. An inspection door 505 is provided below the front plate 501. The front plate 501, the first side plate 502, the back plate 504, and the second side plate 503 are all fixedly connected to the main frame 10 by self-tapping screws. In addition, one side of the inspection door 505 is fixedly connected to the main frame 10 by a hinge, while the other side is fixed by magnetic attraction, which facilitates opening the door to obtain the test results.
