[0001] This invention relates to an automated clamping device for solar panel grids, which uses a push rod system to fix and clamp the grid material, achieving precise positioning and clamping of the grid material. It belongs to the field of clamping technology, and particularly relates to an automated clamping device for solar panel grids. Background Technology

[0002] As a safe, reliable, inexpensive, readily available, and recyclable chemical power source, storage batteries are increasingly being used across various industries. The battery grid, a key component, plays a crucial role in energy conversion; therefore, efficient automated production equipment for battery grids has always been a focus of industry research. Currently, the most common grid clamping devices in the industry use manual feeding, followed by hammering the grid into the mold. This method has a high rate of damage to the grid raw materials and is inefficient. Especially for battery grids with complex structures and nested core materials, high precision is required for the outer surface and dimensions of the grid. Therefore, manual hammering can no longer meet the high-precision requirements of grid installation.

[0003] Given this situation, it is necessary to design an automated plate clamping device that is simple in structure, has high clamping accuracy, and is easy to transfer. Summary of the Invention

[0004] The purpose of this invention is to solve the problem that the clamping mechanism in the prior art is complex in structure and cannot meet the requirements for the accuracy of the outer surface and dimensions of the grid, and to provide an automated clamping device for battery grids.

[0005] To achieve the purpose of this invention, the following technical solution is adopted: This invention discloses an automated clamping device for solar panel grids, comprising: a mold tray, floating pins, fixed pins, movable push rods, springs, washers, and retaining rings. The mold tray is rectangular, and the solar panel grids are clamped on the front side of the mold tray. Several parallel push rod slots are formed along the length of the mold tray on its back side. Several floating pin through slots are formed perpendicularly to the upper and lower sides of each push rod slot. A spring slot is formed perpendicularly to the upper and lower sides of each floating pin through slot, and the spring slot communicates with the floating pin through slot. The movable push rod is installed in a push rod slot spanning the length of the mold tray. A floating pin is installed in each of the floating pin through slots above and below the push rod slot. The two ends of the floating pin pass through the front side of the mold tray and the fixed pin slot, respectively. On the back of the mold tray, a shim is installed between two floating pins on the same movable push rod. A retaining ring is fastened to the end of the floating pin facing the back of the mold tray, axially fixing the floating pin. A spring is installed on each spring groove, and the spring presses against the floating pin, causing the floating pin to press against the movable push rod. Fixed pins are installed on the front of the mold tray between two adjacent floating pins along the length of each movable push rod. The diameter of the movable push rod cross-section is different. Pushing the movable push rod from one end increases or decreases the distance between the two floating pins on the same movable push rod. The battery grid is fitted between several pairs of two opposing floating pins and several opposing fixed pins on the front of the mold tray, both on the same movable push rod.

[0006] The present invention discloses an automated clamping device for battery grids, wherein: a groove is provided on one end near the floating pin, a retaining ring is fitted on the groove, and the retaining ring is a spring ring with a notch; the other end of the floating pin is a tapered head.

[0007] The present invention provides an automated clamping device for solar panel grids, wherein: the push rod groove is a blind groove; the spring groove is a blind groove.

[0008] The present invention discloses an automated clamping device for battery grids, wherein: there is only one spring groove between adjacent movable push rods, the spring groove is connected to two floating pin through grooves above and below, and a spring is installed on the spring groove, the spring respectively abutting the corresponding two floating pins of the adjacent movable push rods.

[0009] The present invention provides an automated clamping device for battery grids, wherein: along the length direction of the movable push rod, at the floating pin that contacts it, the diameter of the movable push rod is gradually changing, and pushing the movable push rod causes the two floating pins above and below the same movable push rod to open or retract.

Detailed Implementation

[0012] like Figures 1 to 5 As shown, an automated clamping device for battery grids according to the present invention includes: a mold tray 1, a floating pin 2, a fixed pin 3, a movable push rod 4, a spring 5, a washer 6, and a retaining ring 8. The mold tray 1 is rectangular, and the battery grid 7 is clamped on the front side 12 of the mold tray. Several parallel push rod grooves 10 are formed along the length of the back side 13 of the mold tray. Several floating pin through grooves 11 perpendicular to each push rod groove 10 are formed on the upper and lower sides along the length of each push rod groove 10. A spring groove 9 perpendicular to each floating pin through groove 11 is formed on the upper and lower sides of each floating pin through groove 11. The spring groove 9 and the floating pin through groove 11 are connected. 1. The movable push rod 4 is installed in the push rod groove 10 spanning the length of the mold tray 1. A floating pin 2 is installed in the floating pin through groove 11 above and below the push rod groove 10. The two ends of the floating pin 2 pass through the front 12 and the back 13 of the mold tray, respectively. A shim 6 is installed between the two floating pins 2 above and below the same movable push rod 4 on the back 13 of the mold tray. There is a groove 14 near one end of the floating pin 2. The retaining ring 8 is a spring ring with a notch. The retaining ring 8 is fitted on the groove 14 to fix the floating pin 2 axially. The other end of the floating pin 2 is a tapered head. A spring 5 is installed on each spring groove 9, and the spring 5 presses against the floating pin 2, so that the floating pin 2 presses against the movable push rod 4. The fixed pin 3 is installed on the front side 12 of the mold tray between two adjacent floating pins 2 along the length direction of each movable push rod 4. The diameter of the cross section of the movable push rod 4 is different. Pushing the movable push rod 4 from one end increases or decreases the distance between the two floating pins 2 above and below the same movable push rod 4. The battery grid 7 is fitted between several pairs of two relative floating pins 2 and several relative fixed pins 3 above and below the same movable push rod 4 on the front side 12 of the mold tray.

[0013] The push rod groove 10 is a blind groove; the spring groove 9 is a blind groove. There is only one spring groove 9 between adjacent movable push rods 4. The spring groove 9 is connected to the two floating pin through grooves 11 above and below. A spring 5 is installed on the spring groove 9. The spring 5 presses against the corresponding two floating pins 2 of the adjacent movable push rods 4.

[0014] like Figure 4 As shown, along the length of the movable push rod 4, at the floating pin 2 that contacts it, the diameter of the movable push rod 4 gradually changes. Pushing the movable push rod 4 causes the two floating pins 2 above and below the same movable push rod 4 to open or retract.

[0015] Working principle of the invention: like Figure 1 , Figure 2 and Figure 3 The battery grid 7 enters vertically downwards into the mold tray 1 located below through the material clip, and under the guidance and positioning of the fixed pin 3, the grid material is precisely positioned in the left, right, up, and down directions. At this time, a thrust is applied from left to right, pushing the movable push rod 4 located in the corresponding groove below the tray to move from left to right. The inclined surfaces distributed on the movable push rod 4 push the floating pins 2 distributed on both sides of it to move from the inside to the outside. At the same time, the floating pins 2 compress the springs 5 ​​located on both sides of them. The upper end of the floating pins 2 squeezes the inner ring of the battery grid 7, thereby completing the vertical positioning of the workpiece. That is, the conical head of the floating pins 2 plays a role in preventing the grid material from lifting and demolding. At the same time, by controlling the inclined surfaces distributed on the movable push rod 4, the dimensional accuracy of the inner ring of the workpiece can be precisely controlled, preventing the workpiece from deforming under the action of external force during the flow process. When the workpiece needs to be demolded, a pulling force from right to left is applied to the movable push rod 4, and the movable push rod returns to its initial position. Under the action of the springs 5 ​​on both sides, the floating pin 2 returns to its initial position, the vertical upward limit of the solar panel grid 7 is released, and the solar panel grid 7 can be demolded from the vertical upward direction.

[0016] The above description only discloses specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or modifications that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
