Description

Technical Field

[0002] Automated aging test production lines typically use double-speed conveyor lines to transport jigs. At certain workstations, the workpiece to be operated must be rotated a certain angle. Because it is on the conveyor line, it must first be lifted and then turned. Existing technology often uses a reduction motor to provide rotational power. The reduction motor is connected to a gear train, and the rotating carrier is fixed to the large gear of the gear train. This rotation is achieved through gear transmission, which is prone to gear wear over time. The transmission mechanism requires high machining precision, making it difficult to install and debug, prohibitively expensive, space-consuming, and prone to interference.

[0003] Therefore, it is urgent to design a transfer device and a production line to solve the above problems. Utility Model Content

[0014] As an optional solution, the projection of the starting end of the spiral groove in the vertical direction and the projection of the ending end of the spiral groove in the vertical direction are located at both ends of the diameter of the drum.

[0035] The present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are intended only to illustrate the present invention and are not intended to limit the present invention. It should also be noted that, for ease of description, the accompanying drawings only illustrate portions relevant to the present invention, not all of its components.

[0036] In the description of this utility model, unless otherwise specified or limited, the terms "connected," "connect," and "fixed" should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0037] In the present invention, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may include the first and second features being in direct contact, or may include the first and second features being in contact not directly but through another feature between them. Moreover, a first feature being "above," "above," and "above" a second feature may include the first feature being directly above or obliquely above the second feature, or may simply mean that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.

[0038] In the description of this embodiment, terms such as "upper," "lower," "left," and "right" are used to refer to positions or locations based on the positions or locations shown in the accompanying drawings. These terms are intended solely to facilitate description and simplify operation, and are not intended to indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this invention. Furthermore, the terms "first" and "second" are used solely for descriptive purposes and have no special meaning.

[0039] This embodiment provides a transfer device, in which lifting and turning can be achieved without using gears or reduction motors to output rotational motion, which is easy to install and debug, low in cost, and takes up little space. Figure 1-Figure 3As shown, the transfer device includes a lifting drive mechanism 10 and a rotating mechanism 20. The lifting drive mechanism 10 can output movement in the vertical direction. The rotating mechanism 20 includes a base 21, a lifting drive assembly 22, a rotating assembly 23 and a lifting member 24. The base 21 is connected to the output end of the lifting drive mechanism 10; the lifting drive assembly 22 is connected to the base 21 and can output movement in the vertical direction; the rotating assembly 23 is pivoted to the base 21 with the vertical direction as the axis, and the top of the rotating assembly 23 is used to place the part to be operated. The rotating assembly 23 is provided with a spiral groove 2311, and the lifting member 24 slides in the spiral groove 2311 and is connected to the output end of the lifting drive assembly 22.

[0040] The above-mentioned transfer device realizes the lifting and lowering of the rotating mechanism 20 through the lifting drive mechanism 10. When the rotating mechanism 20 is lifted to a certain height, the lifting drive component 22 drives the lifting member 24 to rise or fall. Since the rotating component 23 has a spiral groove 2311, when the lifting member 24 rises or falls, the lifting member 24 slides in the spiral groove 2311, thereby driving the rotating component 23 to rotate with the vertical direction as the axis. Therefore, the transfer device realizes the lifting and turning of the operated part by relying solely on linear output without using gears or reduction motors. It is easy to install and debug, has low cost, and occupies little space.

[0041] It should be noted that the workpiece to be operated may be a fixture or a product in a production line, etc., which is not limited here.

[0042] Alternatively, as Figure 1 and Figure 3 As shown, the rotating assembly 23 includes a rotating drum 231 and a rotating disk 232. The bottom of the rotating drum 231 is pivotally connected to the base 21, and a spiral groove 2311 is defined along the axial direction of the rotating drum 231. The rotating disk 232 is connected to the top of the rotating drum 231 and slides with the base 21. The upper side of the rotating disk 232 is used to place the workpiece to be operated. With this arrangement, the lifting action of the lifting member 24 drives the rotating drum 231 to rotate, which in turn drives the rotating disk 232, which carries the workpiece to be operated, to rotate.

[0043] Alternatively, as Figure 1 As shown, at least two positioning pins 233 are provided on the turntable 232, and the positioning pins 233 are plugged into and matched with the workpiece to be operated, so as to facilitate the placement of the workpiece to be operated on the turntable 232. The workpiece to be operated can be a jig or other parts, which is not limited here.

[0044] Optionally, the base 21 includes a bottom plate 211 and a first connecting member 212, the bottom plate 211 is connected to the output end of the lifting drive mechanism 10, the turntable 232 slides with the bottom plate 211, the bottom plate 211 has an avoidance hole 2111, the first connecting member 212 is U-shaped and connected to the lower side of the bottom plate 211, the bottom of the rotating cylinder 231 is pivotally connected to the horizontal part of the first connecting member 212, through the above arrangement, part of the rotating cylinder 231 can be set on the lower side of the bottom plate 211, thereby reducing the setting height of the turntable 232, and reducing the space occupied by the device.

[0045] In other embodiments, the first connecting member 212 may also be connected to other positions of the bottom plate 211 , which is not limited here.

[0046] Alternatively, as Figure 3 and Figure 4 As shown, the vertical projections of the starting end 23111 of the spiral groove 2311 and the vertical projections of the ending end 23112 of the spiral groove 2311 are located at opposite ends of the diameter of the rotating drum 231. With this arrangement, the lifting member 24 slides from the starting end 23111 of the spiral groove 2311 to the ending end 23112 of the spiral groove 2311 as it ascends, achieving a 180° rotation of the rotating drum 231, and thereby achieving a 180° rotation of the operating member. It should be noted that the starting end 23111 and the ending end 23112 are interchangeable.

[0047] Of course, when the rotation angle requirement of the part to be operated changes, different spiral grooves 2311 can be opened according to the requirements so that the starting end 23111 and the ending end 23112 meet the rotation angle requirement.

[0048] Alternatively, as Figure 3 and Figure 4 As shown, there are two spiral grooves 2311. The starting ends 23111 of the two spiral grooves 2311 are at the same height, and the ending ends 23112 of the two spiral grooves 2311 are at the same height. The lifting members 24 are arranged in a one-to-one correspondence with the spiral grooves 2311. In other words, the two lifting members 24 rise or fall simultaneously, improving the balance of forces on both sides of the rotating drum 231 when it rotates.

[0049] Alternatively, as Figure 2 and Figure 3As shown, the base 21 also includes two second connecting members 213, and the two second connecting members 213 are connected to the lower side of the bottom plate 211 and are respectively located on the opposite sides of the avoidance hole 2111. There are two second connecting members 213. At the same time, the lifting drive assembly 22 includes two second lifting drive members 221. The two lifting members 24 are arranged one-to-one at the output ends of the second lifting drive members 221. The second lifting drive members 221 are installed one-to-one on the second connecting members 213. Through the above arrangement, the installation of the second lifting drive member 221 can be facilitated, and the simultaneous rise or fall of the two lifting members 24 can be achieved.

[0050] Alternatively, as Figure 2 and Figure 3 As shown, the lifting drive assembly 22 further includes a third connecting member 222. The third connecting member 222 is frame-shaped. The hollow space in the middle of the third connecting member 222 allows the rotating drum 231 to pass through to prevent interference. The two ends of the third connecting member 222 are respectively connected to the output ends of the two second lifting members 24, and the two lifting members 24 are mounted on the third connecting member 222. It can be understood that by providing the third connecting member 222, the lifting and lowering of the two lifting members 24 are synchronized, avoiding the situation where there is a slight time difference between the lifting and lowering of the two second lifting members 24, which may cause the rotation of the rotating drum 231 to jam.

[0051] Optionally, the second lifting drive member 221 is a cylinder. In other embodiments, the second lifting drive member 221 may also be a linear motor, etc., which is not limited here.

[0052] Alternatively, as Figure 4 As shown, the lifting member 24 is a bearing, which can reduce the friction of the lifting member 24 in the spiral groove 2311, reduce the wear of the rotating drum 231 and the lifting member 24, and extend the service life.

[0053] Alternatively, as Figure 1 As shown, a protrusion 234 is provided on the turntable 232, and two stoppers 25 are provided on the base plate 211. One of the stoppers 25 is configured to stop the protrusion 234 when the lifting member 24 is located at the starting end 23111 of the spiral groove 2311, and the other stopper 25 is configured to stop the protrusion 234 when the lifting member 24 is located at the ending end 23112 of the spiral groove 2311. This arrangement provides a double guarantee for the rotation angle of the operating member (the starting end 23111 and the ending end 23112 of the spiral groove 2311 are the first guarantee, and the above arrangement is the second guarantee). At the same time, it prevents the spiral groove 2311 from being machined with insufficient precision, which could result in inaccurate rotation angles due to slight changes in the rotation angle.

[0054] Optionally, the limiting member 25 is a buffer. It can avoid hard collision between the limiting member 25 and the limiting protrusion 234, and play a role in cushioning. The buffer includes but is not limited to a hydraulic buffer, a rubber pad, etc., which are not limited here.

[0055] Alternatively, as Figure 5 and Figure 6 As shown, the lifting drive mechanism 10 includes two first lifting drive members 11, a base plate 211 is simultaneously connected to the output ends of the two first lifting drive members 11, the lifting member 24 is a cylinder, and the output end of the first lifting drive member 11 is connected to the I-shaped member 12, the peripheral side of the I-shaped member 12 is provided with a receiving groove 121, the base plate 211 is provided with a locking hole 2112, the I-shaped member 12 is penetrated by the locking hole 2112, and the base plate 211 is limited in the receiving groove 121, and the side walls and bottom walls of the receiving groove 121 are all gapped with the base plate 211. Through the above arrangement, the gap allows the output end of the first lifting drive member 11 to have a certain floating range. When the two first lifting drive members 11 are used to drive the base plate 211 to rise and fall simultaneously, the output ends of the two first lifting drive members 11 are prevented from being lifted to different heights, causing one of them to be "stifled" and stuck.

[0056] Alternatively, see Figure 1 and Figure 6 The bottom plate 211 is provided with a through hole 2113, which is connected to the locking hole 2112 and matches the diameter of the large diameter end of the I-shaped piece 12. The locking hole 2112 is a partially oblong hole. With the above arrangement, when installing the bottom plate 211, the lifting member 24 is already in place. At this time, the two through holes 2113 are aligned with the two I-shaped pieces 12 respectively, and the bottom plate 211 is lowered. The bottom plate 211 is then translated so that the I-shaped pieces 12 enter the locking holes 2112, facilitating the installation of the bottom plate 211. Similarly, the removal of the bottom plate 211 is the opposite process. The above arrangement facilitates the installation and removal of the bottom plate 211.

[0057] This embodiment also provides a production line including the transfer device described above. The transfer device is used between two workstations of the production line. By using the transfer device, the installation and commissioning of the entire production line is more convenient, cost-effective, and interference between devices is less likely to occur.

[0058] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here.
