Description

Technical Field

[0001] This invention relates to the field of alkaline water hydrogen production electrode plate processing technology, specifically to an automatic positioning device for alkaline water hydrogen production electrode plates. Background Technology

[0002] Alkaline water hydrogen production is one method of hydrogen production through water electrolysis. It involves passing electricity through alkaline deionized water to decompose hydroxide ions. The electrolytic cell consists of a cell body, an anode, and a cathode, with a diaphragm separating the anode and cathode chambers in most cases. When direct current passes through the electrolytic cell, an oxidation reaction occurs at the anode-solution interface, and a reduction reaction occurs at the cathode-solution interface, producing the desired product. The electrode plates are an important component in the alkaline water hydrogen production process.

[0003] Common large material positioning typically requires overhead cranes within the workshop to grasp and move the product, aligning it with positioning pins or reference points. However, the large travel range of the overhead cranes within the workshop results in long material movement distances, leading to slow positioning speeds and safety risks, thus reducing positioning efficiency.

[0030] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0031] like Figure 1-6 As shown in the figure, an automatic positioning device for alkaline water hydrogen production electrode plates provided in this embodiment of the invention includes a base plate 1, a moving component 2 on the top of the base plate 1, a height adjustment component 3 and a column 48 on the moving component 2, a support plate 4 on the top of both the height adjustment component 3 and the column 48, and at least one support component 5 on the top of each support plate 4; a center positioning mechanism is also provided on the top of the support plate 4; the moving component is used to drive the height adjustment component 3 and the column 48 to move the support plate 4 closer or further apart, so that the center positioning mechanism can achieve center positioning of the electrode plate; the center positioning mechanism is provided in multiple ways, each center positioning mechanism includes three fixed cam followers 7, one adjustable cam follower 7, and an adjustment component 6 for adjusting the adjustable cam follower 7.

[0032] When the first electrode plate is positioned, the cam follower 7 contacts the electrode plate and pushes it. The electrode plate transmits torque through the height adjustment component 3 and the column 48 to the moving component 2. The motor driver senses the torque feedback and reduces the operating speed of the drive motor 40. When other cam followers 7 also touch the electrode plate, since the cam followers 7 are circularly positioned, according to the principle of three points determining a circle, the center of the electrode plate eventually coincides with the center of the circle formed by all the cam followers 7 of the same center positioning mechanism. At this time, the electrode plate no longer moves, the torque sensed by the motor driver reaches the predetermined value, and controls the drive motor 40 to stop rotating. The positioning of the first electrode plate is completed.

[0033] The cam follower 7 can push the electrode plate without causing friction damage to the electrode plate, thereby increasing the stability of the electrode plate positioning.

[0034] Reference Figure 2 The moving component 2 in this embodiment includes two lead screws 37, a connecting shaft 38, an L-shaped plate 39, a drive motor 40, a first synchronous pulley 41, a second synchronous pulley 42, a transmission belt 43, two moving blocks 44, and a slide rail 45. A moving groove 46 is provided on the top of the base plate 1. The two lead screws 37 are rotatably mounted in the moving groove 46. The connecting shaft 38 is fixedly mounted between the two lead screws 37. The L-shaped plate 39 is fixedly mounted on the top of the base plate 1. The drive motor 40 is fixedly mounted on the top of the L-shaped plate 39. The first synchronous pulley... 41 is rotatably mounted on one side of the L-shaped plate 39. The first synchronous pulley 41 is connected to the output end of the drive motor 40. The second synchronous pulley 42 is sleeved on the outer surface of the connecting shaft 38. The transmission belt 43 is sleeved between the second synchronous pulley 42 and the first synchronous pulley 41. The tooth ratio of the first synchronous pulley 41 to the second synchronous pulley 42 is 1:2. The two lead screws 37 have the same diameter and lead, and the screw thread direction is opposite. The height adjustment component is set on the top of one of the moving blocks, and the column 48 is set on the top of the other moving block 44.

[0035] This invention provides an automatic positioning device for alkaline water hydrogen production electrode plates. Four cam followers 7 of the same centered positioning mechanism are distributed on two support plates 4, with one cam follower 7 installed at each of the top two ends of each support plate 4. The two lead screws 37 in the moving assembly 2 have the same diameter, consistent lead, and opposite thread directions, ensuring synchronized movement of the two lead screws 37 and thus guaranteeing the positioning accuracy of the electrode plates.

[0036] The movable component 2 can drive the support plate 4 to move, thereby automatically positioning the electrode plate. The first synchronous pulley 41 and the second synchronous pulley 42, with a gear ratio of 1:2, enable the drive motor 40 to drive the automatic positioning device with less power.

[0037] The movable block 44 is slidably installed in the movable groove 46. Each movable block 44 is threadedly connected to the lead screw 37. The bottom of the movable block 44 is provided with a slider. The slide rail (45) is slidably connected to the slider. The slide rail 45 is fixedly connected to the base plate 1. The top of the base plate 1 is provided with a grating ruler. The bottom of the movable block 44 is provided with a reading head. The drive motor 40 is provided with a motor driver on one side.

[0038] The slide rail 45 can limit the movement of the moving block 44, thereby increasing the stability of the moving block 44 during movement. The reading head can cooperate with the grating ruler, thereby making the movement distance of the moving block 44 more accurate.

[0039] Reference Figure 5In this embodiment, the adjustment component 6 includes a square groove 8 formed on the top of the support plate 4, a first square plate 9 slidably installed in the square groove 8, a first limiting groove 10 formed on the top of the first square plate 9, an anti-slip pad 12 fixedly installed on the bottom of the first square plate 9, a second limiting groove 13 formed in the square groove 8, a second square plate 14 slidably installed in the second limiting groove 13, a third limiting groove 15 formed on the top of the second square plate 14, a square block 11 slidably installed between the first limiting groove 10 and the third limiting groove 15, and a sensor provided on the top of the support plate 4.

[0040] After the first electrode plate of each diameter size is positioned, the adjustment component 6 can adjust the position of the adjustable cam follower 7 so that all cam followers 7 of the same center positioning mechanism are located on the same circular surface (circular trajectory), so that the cam follower 7 automatically positions the electrode plate, thereby saving working space and working time, and thus increasing the positioning efficiency of the electrode plate.

[0041] Please continue to refer to Figure 6 In one specific embodiment, the center positioning mechanism at the top of the support plate 4 is set to three, A, B, and C. Due to processing and assembly errors, it cannot be guaranteed that the four cam followers 7 of the same center positioning mechanism will initially be on the same circular surface. Therefore, three of them are set to fixed type, and one is set to adjustable type. Taking group A as an example, the four cam followers 7 are A1, A2, A3, and A4, where A1, A2, and A3 are fixed cam followers 7, and A4 is an adjustable cam follower 7. When the first pole plate of each diameter size is placed on the top of the support plate 4, as the moving component 2 drives the height adjustment component 3 and the column 48 to move the support plate 4 in opposite directions, the three fixed cam followers 7 (A1, A2, A3) first contact the pole plate to achieve three-point circle positioning. Then, the pole plate is manually rotated, and the side of the pole plate is measured by a dial indicator. The center can be determined by the dial indicator pointer jumping within ±0.05. Subsequently, by adjusting component 6, the adjustable cam follower 7 (A4) is fixed close to the side of the electrode plate, allowing the four cam followers 7 to be mounted on the same circular surface. Afterward, all four cam followers 7 of the same centered positioning mechanism can position the electrode plate of that diameter, accelerating the positioning speed.

[0042] Please continue to refer to Figure 6The diagram shows the symmetrical center lines of the two support plates 4. Since the two support plates 4 are relatively movable, the moving component 2 drives the two support plates 4 to move relative to each other according to the diameter of the electrode plate, such that the angle between the line connecting the cam follower 7 and the center of the electrode plate and the symmetrical center line of the two support plates 4 is 45°. This invention provides an automatic electrode plate positioning device for alkaline water hydrogen production. By setting multiple center positioning mechanisms, when positioning electrode plates of corresponding diameters, the angle between the line connecting each cam follower 7 and the center of the electrode plate and the symmetrical center line of the two support plates 4 is 45°, thereby ensuring uniform force distribution when positioning the electrode plates.

A circular frame 18 is provided on the outer surface of the cylinder 16, and a first spring 19 is fixedly installed between the circular plate 17 and the circular frame 18. The first spring 19 can press the second square plate 14 against the first square plate 9 through the circular frame 18, thereby increasing the stability of the adjustment component 6 during use.

A slot 33 is provided at the top of the support plate 4, and the T-shaped plate 24 is secured within the slot 33. The support assembly 5 can support the electrode plate without affecting its movement, thereby improving the stability of the electrode plate during positioning. The pressure plate 29 can control the buckle 27's limiting of the T-shaped plate 24 and the support plate 4, thus facilitating the disassembly and assembly of the support assembly 5 for maintenance.

[0045] The first support frame 25 is set on the top of the T-shaped plate 24. The top of the first support frame 25 has a first sliding groove 34.

The column 48 is fixedly connected to the support plate 4. The height adjustment component 3 can adjust the height of the support plate 4 as needed, thereby preventing unevenness at both ends of the electrode plate and increasing the flexibility of the automatic positioning device during use.

[0048] The height adjustment frame 49 is fixedly installed on the top of the movable block 44. The top of the height adjustment frame 49 has a height adjustment groove 57. The height adjustment plate 50 is slidably installed in the height adjustment groove 57. The height adjustment plate 50 is fixedly connected to the support plate 4.

[0049] The workflow of this invention is as follows:

[0050] 1) Based on the diameter of the electrode plate, the moving component 2 is used to drive the two support plates 4 to maintain a certain distance between them;

[0051] 2) Place the electrode plate on the two support plates 4, with the electrode plate in contact with the top of the slide bar 32;

[0052] 3) When the sensor detects that the electrode plate is in position, the two ends of the electrode plate are leveled by adjusting component 3;

[0053] 4) Activate the moving component 2 to make the two support plates 4 move towards each other. When a portion of the cam follower 7 touches the electrode plate, it pushes the electrode plate to move towards the center.

[0054] 5) When all the fixed cam followers 7 of the same center positioning mechanism touch the side of the electrode plate, manually rotate the electrode plate and measure the side of the electrode plate with a lever dial indicator. The center can be determined when the dial indicator pointer jumps within ±0.05.

[0055] 6) By adjusting component 6, the adjustable cam follower 7 is fixed close to the side of the electrode plate, so that the four cam followers 7 of the same center positioning mechanism can be installed on the same circular surface.

Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
