Description
Technical Field
[0001] The utility model relates to the technical field of new energy battery production. Background Art
[0002] In the production process of new energy blade batteries, "battery transfer" is required to ensure subsequent blade batteries (hereinafter referred to as "electric cores"). Since the size of blade batteries is quite different from that of traditional square aluminum shell batteries, in order to ensure the smooth, fast and stable mutual operation of each electric core between workstations, it is necessary to ensure the accurate and firm position of each electric core during the grasping and transfer process. At present, the production line beat and automation level of new energy are gradually increasing, and the requirements and standards for products by users are also becoming stricter day by day. Therefore, a fully automatic, high-speed, highly stable and safe handling mechanism is needed. Summary of the Utility Model
[0003] In order to ensure the accurate position during the transfer of electric cores, the utility model provides an electric core stacking handling gripper.
[0004] The technical solution adopted by the utility model to achieve the above purpose is as follows:
[0005] An electric core stacking handling gripper, a variable pitch guide rail 2 and a variable pitch cylinder 3 are installed in parallel on the lower side of a support plate 1. The variable pitch cylinder 3 is connected to a first bracket 4. The first bracket 4 is installed on the variable pitch guide rail 2. A second bracket 5 is installed on the variable pitch guide rail 2. An adjustable pitch cylinder 6 is installed on the second bracket 5. The cylinder rod of the adjustable pitch cylinder 6 is connected to the first bracket 4. A flipping cylinder 7 is installed on each of the first bracket 4 and the second bracket 5. The flipping cylinder 7 is connected to a jaw cylinder 9 through a flipping frame 8. The jaw cylinder 9 is connected to a jaw block 10.
[0006] A jaw bracket 14 is installed on the left side of the flipping frame 8. Jaw cylinders 9 are installed at the front and rear ends of the jaw bracket 14. A proximity switch 17 is installed on the inner side of the two jaw cylinders 9 of the jaw bracket 14 through a fixing plate 18.
[0007] A limit plate 15 is installed on the right side of the flipping frame 8. Flipping stop buffers 16 are installed on the first bracket 4 and the second bracket 5 corresponding to the limit plate 15.
[0008] The variable pitch cylinder 3 is connected to a variable pitch stop plate 12 through a floating joint 11. The variable pitch stop plate 12 is connected to the first bracket 4. Variable pitch stop buffers 13 cooperating with the variable pitch stop plate 12 are installed at both ends of the variable pitch guide rail 2 on the support plate 1.
[0009] A robot connection flange 19 is installed on the upper side of the support plate 1.
[0010] The advantages of the utility model compared with the prior art are as follows:
[0011] After the gripper cylinder grabs the battery cell, the distance between each gripper cylinder is adjusted by the pitch-changing cylinder and the spacing-adjusting cylinder, so that the distance between each battery cell is kept consistent, and the gripper cylinder is flipped by the flipping cylinder to flip the battery cell. While transporting the battery cell, the spacing between the battery cells is adjusted and flipped, improving the accuracy of the battery cell transfer position and the production efficiency.

[0018] A battery cell stacking and handling gripper provided by the present utility model, such as Figures 1 - 3As shown in the figure, a robot connection flange 19 is installed on the upper side of the support plate 1. A variable pitch guide rail 2 and a variable pitch cylinder 3 are installed in parallel on the lower side of the support plate 1. The variable pitch cylinder 3 is connected to a variable pitch blocking plate 12 through a floating joint 11. The variable pitch blocking plate 12 is connected to a first bracket 4. Variable pitch blocking buffers 13 that cooperate with the variable pitch blocking plate 12 are installed at both ends of the variable pitch guide rail 2 on the support plate 1 to prevent excessive movement of the first bracket 4. The first bracket 4 is installed on the variable pitch guide rail 2. A second bracket 5 is installed on the variable pitch guide rail 2. An adjustable pitch cylinder 6 is installed on the second bracket 5. The cylinder rod of the adjustable pitch cylinder 6 is connected to the first bracket 4. Tipping cylinders 7 are installed on both the first bracket 4 and the second bracket 5. The tipping cylinders 7 are connected to jaw cylinders 9 through tipping frames 8. The jaw cylinders 9 are connected to jaw blocks 10. A jaw bracket 14 is installed on the left side of the tipping frame 8. Jaw cylinders 9 are installed at both the front and rear ends of the jaw bracket 14. A proximity switch 17 is installed on the inner side of the two jaw cylinders 9 of the jaw bracket 14 through a fixing plate 18. The proximity switch 17 is used to detect the position of the battery cell. A limit plate 15 is installed on the right side of the tipping frame 8. Tipping blocking buffers 16 are installed on the first bracket 4 and the second bracket 5 corresponding to the limit plate 15.
[0019] Working principle: The gripper of this application is installed on the robot through the robot connection flange 19. When the proximity switch 17 detects the battery cell, the jaw cylinder 9 controls the jaw block 10 to grab a total of four battery cells placed horizontally on the large wide surface. Subsequently, the first bracket 4 is pushed to move by the variable pitch cylinder 3. Then, the second bracket 5 is pushed to move by the adjustable pitch cylinder 6, so that the distance between the four battery cells changes from the original 220 mm to 265 mm. As Figure 4 shown, at this time, the limit plate 15 is horizontal and the jaw block 10 is in a vertical state. After the jaw cylinder 7 grabs the battery cell, as Figure 5 shown, the tipping cylinder 7 flips, causing the battery cell to flip 90°. At this time, the limit plate 15 is in a vertical state and contacts the tipping blocking buffer 16, and the jaw block 10 is in a horizontal state, so that the battery cell is flipped from the large wide surface horizontal state to the large narrow surface horizontal state. After the flipping is completed, the gripper places the 4 battery cells on the pre-stacking table. Subsequently, the jaw cylinder 9 opens, and the gripper withdraws and returns to the original position.
