Description

Technical Field

[0001] This utility model relates to the field of glass production technology, specifically to a robotic arm used in glass production lines. Background Technology

[0002] A glass cup is a container used to store water and is a common daily necessity. During the production of glass cups, robotic arms are used to transfer the glass cups from the previous process equipment to the next process equipment.

[0003] Currently, when a robotic arm transfers a glass from one side to a conveyor line, it typically uses a combination of a linear cylinder, a rotary cylinder, and an L-shaped plate. Specifically, the linear cylinder extends to move the L-shaped plate against the side wall of the glass, while the rotary cylinder rotates to rotate the linear cylinder and the L-shaped plate, thus moving the glass onto the conveyor line.

[0004] When the rotary cylinder finishes feeding the glass and resets, the linear cylinder needs to retract the L-shaped plate before returning to the initial position to avoid moving the glass (which is the new glass to be fed) during the return stroke. After returning to the initial position, the linear cylinder needs to extend the L-shaped plate to move the glass onto the conveyor line, which makes the time for a single cycle of glass feeding operation longer. Utility Model Content

[0005] The purpose of this invention is to provide a robotic arm for glass transfer lines to address the aforementioned shortcomings in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A robotic arm for glass transfer lines includes a base, a rotating part rotatably mounted on the base, a stop bar slidably mounted on the rotating part, a guide rod fixedly mounted on the stop bar, and a closed guide groove formed on the base. The guide rod extends into and slidably connects to the guide groove, allowing the stop bar to repeatedly perform a first stroke and a second stroke: First stroke: The rotating part drives the stop bar to rotate along the guide groove, causing the stop bar to rotate around the rotation center axis of the rotating part; Second stroke: The rotating part drives the stop bar to rotate along the guide groove, causing the stop bar to move towards the rotating part during rotation.

[0008] Furthermore, the rotating part includes a rotating seat rotatably connected to the base, the stop lever is slidably connected to the rotating seat, and the rotating seat is also connected to the driving part, which drives the rotating seat to perform a reciprocating oscillating motion.

[0009] Furthermore, the drive unit includes a motor fixedly mounted on the base, a disc fixedly connected to the output shaft of the motor, a limit rod fixedly connected to the disc, a rocker arm fixedly connected to the rotating seat, a limit groove formed on the rocker arm, and the limit rod extending into and slidingly connected to the limit groove.

[0010] Furthermore, the limiting groove is formed along the length of the rocker arm.

[0011] Furthermore, the guide groove includes a first arc-shaped groove and a second arc-shaped groove that are connected at both ends. The two connection points of the first arc-shaped groove and the second arc-shaped groove are respectively provided with guide parts so that the limiting rod can move unidirectionally within the guide groove.

[0012] Furthermore, the guide portion includes a retention groove formed at the connection between the first arc-shaped groove and the second arc-shaped groove, and a protrusion is provided in the retention groove.

[0013] Furthermore, a support frame is fixedly provided at the end of the stop lever, and an arc-shaped locking block is fixedly provided on the side of the support frame away from the rotating part.

[0014] In the above technical solution, the robotic arm for glass transfer provided by this utility model has the following beneficial effects:

[0015] The rotating part drives the stop lever to reciprocate along the guide groove. During the first stroke, the stop lever rotates along with the glass cup, rotating around the central axis of the rotating part. During the second stroke, the stop lever moves towards the rotating part while rotating, thus avoiding new glass cups to be moved, until it reaches the starting point of the first stroke and begins the next feeding cycle. This invention automatically avoids glass cups to be fed on the return stroke, eliminating the need for separate control of the extension and retraction actions, effectively reducing the time of a single feeding cycle.

[0016] It should be understood that the foregoing general description and the following detailed description are exemplary and illustrative only, and are not intended to limit this disclosure.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure.

[0030] Please see Figure 1-4 A robotic arm for glass transfer lines includes a base 1, a rotating part 2 rotatably mounted on the base 1, a stop bar 3 slidably mounted on the rotating part 2, and a guide rod 31 fixedly mounted on the stop bar 3. A closed guide groove 4 is formed on the base 1, and the guide rod 31 extends into and slidably connects to the guide groove 4, allowing the stop bar 3 to repeatedly perform a first stroke and a second stroke: First stroke: The rotating part 2 drives the stop bar 3 to rotate along the guide groove 4, causing the stop bar 3 to rotate around the rotation center axis of the rotating part 2; Second stroke: The rotating part 2 drives the stop bar 3 to rotate along the guide groove 4, causing the stop bar 3 to move towards the rotating part 2 during rotation.

[0031] The rotating part 2 can drive the stop lever 3 to repeatedly perform the first and second strokes. Thus, after driving the glass to rotate to the corresponding position, during the process of returning to the initial position (the beginning of the first stroke), it can move in the direction of the rotating part 2 to avoid the new glass to be delivered.

[0032] Furthermore, the rotating part 2 includes a rotating seat 21 rotatably connected to the base 1, the stop lever 3 is slidably connected to the rotating seat 21, and the rotating seat 21 is also connected to the driving part 22, which drives the rotating seat 21 to perform reciprocating swinging motion.

[0033] Furthermore, the drive unit 22 includes a motor 221 fixedly mounted on the base 1, a disk 222 fixedly connected to the output shaft of the motor 221, a limit rod 223 fixedly connected to the disk 222, a rocker arm 224 fixedly connected to the rotating seat 21, a limit groove 225 formed on the rocker arm 224, and the limit rod 223 extending into and slidingly connected to the limit groove 225.

[0034] Motor 221 drives disc 222 to rotate, disc 222 rotates and drives limit rod 223 to rotate, limit rod 223 rotates and slides in limit groove 225, thereby driving rocker arm 224 to rotate around the rotation center of rotating seat 21, rotating seat 21 drives stop rod 3 to rotate.

[0035] See appendix Figure 1 and appendix Figure 4 The rotating seat 21 drives the stop lever 3 to rotate counterclockwise as shown in the figure to start the first stroke. According to the quick return characteristic, the speed of the stop lever 3 in the first stroke is greater than the speed in the second stroke, so that it can quickly return to the initial position after the glass is delivered.

[0036] Furthermore, the limiting groove 225 is formed along the length direction of the rocker arm 224.

[0037] Furthermore, the guide groove 4 includes a first arc-shaped groove 41 and a second arc-shaped groove 42 that are interconnected at both ends. Guide portions 43 are respectively provided at the two connection points of the first arc-shaped groove 41 and the second arc-shaped groove 42 to allow the limiting rod 223 to move unidirectionally within the guide groove 4. The guide portions 43 enable the guide rod 31 to repeatedly move within the first arc-shaped groove 41 and the second arc-shaped groove 42; the center of the first arc-shaped groove 41 is collinear with the rotation center axis of the rotating seat 21.

[0038] Furthermore, the guide portion 43 includes a retention groove 431 formed at the connection between the first arc-shaped groove 41 and the second arc-shaped groove 42, and a protrusion 432 is provided in the retention groove 431.

[0039] See appendix Figure 4When the guide rod 31 moves into the retention groove 431, the stop rod 3 drives the guide rod 31 to rotate in the opposite direction. Due to the limitation of the protrusion 432, the stop rod 3 cannot return along the original arc groove, but can only slide along another arc groove, thereby ensuring that the guide rod 31 moves back and forth in the first arc groove 41 and the second arc groove 42.

[0040] Furthermore, a support frame 5 is fixedly provided at the end of the stop lever 3, and an arc-shaped locking block 51 is fixedly provided on the side of the support frame 5 away from the rotating part 2. The locking block 51 is used to restrict the glass from moving out of the movement range of the support frame 5.

[0041] Working principle:

[0042] Motor 221 drives disk 222 to rotate, disk 222 rotates and drives limit rod 223 to rotate, limit rod 223 rotates and slides in limit groove 225, thereby driving rocker arm 224 to rotate around the rotation center of rotating seat 21, rotating seat 21 drives stop rod 3 to rotate; stop rod 3 rotates and drives guide rod 31 to move back and forth along first arc groove 41 and second arc groove 42; when guide rod 31 slides along first arc groove 41, stop rod 3 rotates around the rotation center axis of rotating seat 21, i.e., the first stroke; when guide rod 31 slides along second arc groove 42, stop rod 3 rotates and moves towards rotating seat 21 at the same time, thereby avoiding new glass cups and returning to the starting point of first arc groove 41 for subsequent cycles.

[0043] 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.
