Description

Technical Field

[0001] This utility model relates to the technical field of assembly line positioning devices, specifically an automatic workpiece transfer and positioning device for assembly lines. Background Technology

[0002] As is well known, battery production lines rely on conveyor belts to transport batteries, and positioning devices that move synchronously with the belt surface are installed on the conveyor belt to achieve the positioning and transmission of battery products on the conveyor belt.

[0003] For example, the utility model patent with application announcement number CN208746906U, application announcement date of April 16, 2019, and titled "A Positioning Device for Battery Production Line Conveying" has the following specific structure: a conveyor frame and a positioning cylinder. The conveyor frame has several transmission rods inside, and a conveyor belt is sleeved on the outside of the transmission rods. Several bases are placed on the upper side of the conveyor belt. Support cylinders are fixedly connected to both ends of the bases. The support cylinder is sleeved on one end of a slide rod. A limit plate is fixedly connected to one end of the slide rod inside the support cylinder. A spring A is fixedly connected between the limit plate and the support cylinder. A clamping head is fixedly connected to the other end of the slide rod, and a caster is slidably connected to the clamping head.

[0004] The shortcoming of the existing technology is that by placing the battery in the positioning cylinder and having the push plate slide against the side of the battery to fix the battery in the positioning cylinder and move synchronously with the conveyor belt, the push plate is of a fixed shape. That is, the push plate and the positioning cylinder are difficult to clamp and fix batteries of different diameters, making the positioning device not universal. Utility Model Content

[0020] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0021] Please see Figure 1-6 This utility model provides a technical solution: an automatic workpiece transfer and positioning device for an assembly line, including a frame 1, on which a placement seat 2 with a placement groove 21 is slidably arranged, and a movable seat 3 is symmetrically slidably arranged in the placement groove 21. A first clamp 41 and a second clamp 42 are symmetrically oscillating on the movable seat 3. The first clamp 41 and the second clamp 42 oscillate relative to each other to adjust the opening and closing angle between the first clamp 41 and the second clamp 42.

[0022] Preferred, such as Figure 1As shown, several placement seats 2 are interconnected by connecting rods 9, and multiple sets of placement seats 2 are slidably mounted on the frame 1. A first clamp 41 and a second clamp 42 are symmetrically oscillating on the movable seats 3. Battery workpieces can be inserted into the placement slots 21, and the two movable seats 3 slide closer to each other, allowing the first clamp 41 and the second clamp 42 to act as clamping components 4 to clamp and fix the battery workpiece on both sides, thus achieving stable clamping of the battery workpiece onto the placement seats 2 for transport. If it is necessary to clamp battery workpieces of different diameters, the first clamp 41 and the second clamp 42 can be driven to swing away or closer to each other, thereby adjusting the opening angle between the first clamp 41 and the second clamp 42. This allows for clamping, fixing, and positioning of battery workpieces of different diameters using the adjustable opening angle of the first clamp 41 and the second clamp 42, improving the placement seat 2's ability to position and transport batteries of different diameters and enhancing the versatility of the clamping components 4 on the placement seat 2.

[0023] The first clamp 41 is fixedly provided with a rotating part 411, and the second clamp 42 is fixedly provided with a mounting part 421. The rotating part 411 and the mounting part 421 are arranged coaxially and rotate around each other, and both the rotating part 411 and the mounting part 421 are rotatably mounted on the movable seat 3.

[0024] In the above technical solution, the first clamp 41 and the second clamp 42 swing away from or towards each other, thereby adjusting the opening angle between the first clamp 41 and the second clamp 42. This allows the first clamp 41 and the second clamp 42 with adjustable opening angles to clamp, fix, and position battery workpieces of different diameters, improving the positioning and conveying operation of batteries of different diameters on the placement seat 2 and enhancing the versatility of the clamping component 4 on the placement seat 2.

[0025] In another embodiment of the present invention, a drive rod 5 and a transmission gear 53 are rotatably mounted on the movable seat 3. A first drive tooth 51 and a second drive tooth 52 are fixedly mounted on the drive rod 5. The transmission gear 53 is coupled to the first drive tooth 51 and the first gear ring 412 mounted on the first clamp 41, respectively. The second drive tooth 52 is coupled to the second gear ring 422 of the second clamp 42.

[0026] Preferred, such as Figure 6As shown, the drive rod 5 and the transmission gear 53 are rotatably mounted on the movable seat 3, with the end of the drive rod 5 extending to the outside of the movable seat 3. The first drive tooth 51 of the drive rod 5 is coupled to the first gear ring 412 through the transmission gear 53, while the second drive tooth 52 is coupled to the second gear ring 422. When it is necessary to adjust the opening angle of the first clamp 41 and the second clamp 42, the drive rod 5 can be rotated, thereby driving the first clamp 41 and the second clamp 42 to swing in opposite directions through the first drive tooth 51 and the second drive tooth 52, respectively. This allows the first clamp 41 and the second clamp 42 to swing relative to each other to accommodate battery workpieces of different diameters, improving the stability of the drive adjustment of the first clamp 41 and the second clamp 42.

[0027] In another embodiment of the present invention, both the first clamp 41 and the second clamp 42 are covered with a flexible cover strip 43.

[0028] Preferred, such as Figure 1 As shown, both the first clamp 41 and the second clamp 42 are covered with flexible cover strips 43. When the movable seat 3 slides closer to each other, causing the first clamp 41 and the second clamp 42 to abut and clamp onto the battery workpiece, the flexible cover strips 43 form a contact buffer between the clamp and the battery workpiece, thereby improving the protection of the battery workpiece.

[0029] In another embodiment of the present invention, the first clamp 41 and the second clamp 42 are both L-shaped in cross-section with a bend 7, and the flexible cover 43 covers one side of the opening of the first clamp 41 and the second clamp 42 to form a clamping surface.

[0030] Preferred, such as Figure 4 As shown, both the first clamp 41 and the second clamp 42 are L-shaped pieces with a bend 7, and the opening side of the bend 7 of the first clamp 41 and the second clamp 42 faces the center of the placement groove 21. When the flexible cover 43 covers the outside of the first clamp 41 and the second clamp 42, the flexible cover 43 will cover the opening side of the bend 7 to form a flexible clamping surface. When the movable seat 3 slides closer to each other so that the first clamp 41 and the second clamp 42 clamp the battery workpiece, the flexible clamping surface formed by the flexible cover 43 is in contact with the outer surface of the battery workpiece, thereby improving the clamping stability of the battery workpiece. Secondly, the flexible clamping surface formed by the flexible cover 43 is used to limit and fix the battery workpiece, which makes it easy to clamp battery workpieces with different diameters.

[0031] In another embodiment of the present invention, arc rods 6 are linearly arrayed and rotatably arranged on the corner portions 7 of the first clamp 41 and the second clamp 42. In the default state, the arc rods 6 are perpendicular to the flexible cover 43 and push the flexible cover 43 toward the center of the placement groove 21.

[0032] Preferred, such as Figure 4 As shown, the two ends of the arc-shaped member 6 are rotatably disposed in the rotating grooves 71 opened on the bend portion 7. When the battery workpiece is not clamped, the arc-shaped member 6 is perpendicular to the flexible clamping surface formed by the flexible cover 43, so that the flexible clamping surface of the flexible cover 43 can arch towards the center of the placement groove 21, thereby improving the contact between the battery workpiece and the flexible cover 43 when the battery workpiece is inserted into the placement groove 21, and improving the stability of the battery workpiece placed in the placement groove 21. When the battery workpiece is clamped between the two sets of clamping components 4, the arc-shaped member 6 can push the flexible clamping surface of the flexible cover 43 to adhere tightly to the surface of the battery workpiece, thereby improving the clamping stability of the battery workpiece.

[0033] The rotating groove 71 is equipped with a worm spring that drives the arc rod 6 to return to its default state.

[0034] In another embodiment of this utility model, the rotation axis of the arc rod 6 is arranged perpendicular to the axis of the placement groove 21.

[0035] Preferred, such as Figure 4 As shown, the rotation axis of the arc rod 6 is arranged perpendicular to the axis of the placement groove 21. When the battery workpiece is inserted into the placement groove 21, the battery workpiece contacts the flexible clamping surface of the flexible cover 43, causing the arc rod 6 to rotate towards the bottom of the placement groove 21. At this time, the arc rod 6 also pushes the flexible cover 43 to move towards the bottom of the placement groove 21. Then, the arc rod 6 and the flexible cover 43 apply a fixing force to the bottom of the placement groove 21 to the battery workpiece in the placement groove 21, thereby further improving the fixing stability of the battery workpiece.

[0036] In another embodiment of the present invention, a sliding groove 22 is symmetrically provided in the placement groove 21, and the movable seat 3 is slidably disposed in the sliding groove 22. An elastic member 8 for driving the movable seat 3 to slide closer together is fixedly provided in the sliding groove 22.

[0037] Preferably, the movable seat 3 is slidably disposed in the sliding groove 22 of the placement seat 2 to improve the sliding stability of the movable seat 3. The elastic element 8 can be replaced by any elastic object known to those skilled in the art, such as a spring, an elastic plate, or an airbag.

[0038] In another embodiment of this utility model, the first clamp 41 is a Teflon component.

[0039] Preferably, the first clamp 41 is made of Teflon to improve its wear resistance and service life.

[0040] In another embodiment of this utility model, the second clamp 42 is a Teflon component.

[0041] Preferably, the second clamp 42 is made of Teflon to improve its wear resistance and service life.

[0042] In another embodiment of this utility model, the movable seat 3 is made of Teflon.

[0043] Preferably, the movable seat 3 is made of Teflon to improve its wear resistance and service life.

[0044] Working principle: First, the battery workpiece is inserted into the placement slot 21. The battery workpiece contacts the flexible clamping surface of the flexible cover belt 43, causing the arc rod 6 to rotate towards the bottom of the placement slot 21. At this time, the arc rod 6 also pushes the flexible cover belt 43 to move towards the bottom of the placement slot 21. Then, the arc rod 6 and the flexible cover belt 43 apply a fixing force to the bottom of the placement slot 21 to the battery workpiece in the placement slot 21. Subsequently, the two movable seats 3 slide closer to each other, so that the first clamp 41 and the second clamp 42 act as clamping components 4 to clamp and fix the two sides of the battery workpiece, thereby realizing the stable clamping of the battery workpiece onto the placement seat 2 for transportation. When it is necessary to transport battery workpieces with different diameters, the drive rod 5 can be rotated, and then the first drive tooth 51 and the second drive tooth 52 will drive the first clamp 41 and the second clamp 42 to swing in opposite directions, so that the first clamp 41 and the second clamp 42 can swing relative to each other to clamp battery workpieces with different diameters.

[0045] The foregoing description only illustrates certain exemplary embodiments of the present invention. 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. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
