Description

Technical Field

[0001] This utility model application relates to the field of signal transmission technology, and in particular to a signal transmission device. Background Technology

[0002] To achieve tray fixing or release, when the tray moves to a specific position, such as the loading / unloading station or tray exchange station, the tray fixing / releasing mechanism loosens its clamping grip on the tray. This allows the tray pick-and-place mechanism of the tray transfer device (e.g., a suction head mechanism or a gripper mechanism) to pick up or grab the tray, remove it from the tray fixing / releasing mechanism, move it to the desired position, and then place it back down. The tray is then clamped on another device by another tray fixing / releasing mechanism. The actions of the tray pick-and-place mechanism in picking up or grabbing the tray, and the actions of picking up or grabbing and releasing the tray, as well as the actions of the tray fixing mechanism in clamping or releasing the tray, all require multi-channel signal transmission to complete.

[0003] Currently, most of the aforementioned tray loading and unloading mechanisms (such as suction head mechanisms or gripper mechanisms) and tray fixing and releasing mechanisms are frequently in motion. The multi-channel signal transmission required for controlling these mechanisms typically employs complex electrical connection components or devices, which require improvement in either cost or reliability. Therefore, a new signal transmission device is urgently needed. Utility Model Content

[0027] like Figures 1 to 6As shown, a signal transmission device includes: a rotating unit 200, a first signal transmission unit 400, a second signal transmission unit 500, and an intermediate shaft 300. The first signal transmission unit 400 is connected to the rotating unit 200, and the second signal transmission unit 500 is connected to the intermediate shaft 300. The rotating unit 200 rotates relative to the intermediate shaft 300. The first signal transmission unit 400 can contact the second signal transmission unit 500. The signal transmission device operates in the fixed release operation control of the carrier plate, and / or, the signal transmission device operates in the pick-up and drop operation control of the carrier plate.

[0028] In some embodiments, the rotating unit 200 may be a turntable or a turntable, and the intermediate shaft 300 may be a chrome-plated bar.

[0029] In some embodiments, the rotating unit 200 can be driven to rotate by a drive unit, or the rotating unit 200 can be driven to rotate by a drive unit and a transmission unit. Exemplarily, the drive unit can be a motor, the transmission unit 100 can be a cam divider (e.g., a Chip series) or a gearbox, the rotation angle range can be 360 ​​degrees, the intermediate shaft 300 and the transmission unit 100 can both be mounted on the base plate, the rotating unit 200 rotates relative to the intermediate shaft 300, and the intermediate shaft 300 can be stationary or fixed.

[0030] In some embodiments, a carrier plate fixing and releasing mechanism may be installed on the rotating unit 200. The carrier plate fixing and releasing mechanism performs fixing or releasing operations on the carrier plate. The carrier plate fixing and releasing mechanism can be connected to the first signal transmission unit 400 via a cable.

[0031] In some embodiments, a tray picking and placing mechanism may be installed on the rotating unit 200. This mechanism picks up or releases (i.e., places down) the tray. The tray picking and placing mechanism can be either a tray suction head mechanism or a tray gripping head mechanism, which are existing technologies. For example, existing utility model patents CN221498606U and CN215066095U can be referenced. This involves conventional vacuum adsorption or release (i.e., placing down) of the tray, thereby achieving the action of the tray suction head mechanism adsorbing or releasing the tray. Alternatively, a tray gripping head mechanism (e.g.,...) can be used. Figure 4 , Figure 5 The medium-load tray gripper mechanism C) can be selected from three conventional XYZ direction moving modules (X direction moving module, Y direction moving module, Z direction moving module) and a cylinder gripper mechanism to grip or release the tray (the cylinder drives the grippers to move closer to each other or the cylinder drives the grippers to move further apart to grip or release the tray; the cylinder can be a common pneumatic finger). This utility model application will not elaborate on these. The tray picking and placing mechanism can be connected to the first signal transmission unit 400 via a cable.

[0032] In some embodiments, the first signal transmission unit 400 is fixed on the rotating unit 200 and its position is adjusted with the movement of the rotating unit 200. The second signal transmission unit 500 is fixed on the intermediate shaft 300 and remains relatively stationary. The second signal transmission unit 500 can be connected to the controller via a multi-channel cable. The controller outputs a tray control signal to the second signal transmission unit 500. The tray control signal includes a tray pick-up / place signal and / or a tray fixing / releasing signal. The controller (e.g., a PLC controller, a microprocessor controller, etc.) is a prior art device in the field of existing controllers. For example, see utility model patent CN219970115U, etc. This utility model application will not elaborate on these.

[0033] In some embodiments, a signal transmission device, which can also be a tray control signal transmission device, may have one or more tray fixing and releasing mechanisms, and / or one or more tray picking and placing mechanisms, on its rotating unit 200. The signal transmission device operates (i.e., can be used for) tray fixing or releasing operation control, and / or, the signal transmission device operates (i.e., can be used for) tray picking or releasing operation control. Specifically, it includes:

[0034] When the first signal transmission unit 400 contacts the second signal transmission unit 500, the controller outputs a tray control signal to the second signal transmission unit 500. The tray control signal (e.g., one or more electrical signals) includes one or more tray pick-up / placement signals; and / or one or more tray fixation / release signals. The tray pick-up / placement signal includes a tray pick-up signal or a tray release (i.e., put down) signal, and the tray fixation / release signal includes a tray fixation signal or a tray release signal. The second signal transmission unit 500 transmits the tray control signal to the first signal transmission unit 400, and the first signal transmission unit 400 transmits the tray control signal to the tray pick-up / placement mechanism and / or the tray fixation / release mechanism. The tray pick-up / placement mechanism and / or the tray fixation / release mechanism perform tray fixation or release operations, and / or tray pick-up or release operations, according to the tray control signal.

[0035] In some embodiments, the first signal transmission unit 400 and the second signal transmission unit 500 transmit the tray control signal through physical contact (such as sliding or rolling conductive surfaces), which satisfies the control requirements of the tray pick-up and release mechanism (suction head mechanism or gripper head mechanism) for picking up or releasing (i.e., putting down) the tray, or the tray fixing and release mechanism (see below) for clamping or loosening the tray.

[0036] In this utility model application, compared with complex electrical connection elements or devices, a simplified mechanical and signal transmission design is adopted. Sliding or rotating contact replaces the traditional multi-channel cable signal transmission method, providing a flexible signal transmission method. The reliable contact between the first signal transmission unit and the second signal transmission unit meets the control requirements of the tray. It is suitable for tray loading and unloading or transfer and exchange operations, reduces material and assembly costs, and reduces or avoids maintenance costs caused by cable failures in traditional transmission methods. It is suitable for industrial applications.

[0037] Optionally, the first signal transmission unit 400 is a probe; and / or, the second signal transmission unit 500 is a spring.

[0038] In some embodiments, the spring can be connected to a controller (e.g., a PLC controller, a microprocessor controller, etc.) via a multi-channel cable. The controller outputs a carrier control signal to the second signal transmission unit 500. The carrier control signal (e.g., one or more electrical signals) includes one or more carrier pick-up / placement signals and / or one or more carrier fixation / release signals. The carrier pick-up / placement signal includes a carrier pick-up signal or a carrier release signal, and the carrier fixation / release signal includes a carrier fixation signal or a carrier release signal. The elastic range of the spring 502 can be adjusted according to the contact pressure requirements. The contact method between the probe 402 and the spring 502 can be achieved through the elastic deformation of the spring.

[0039] In some embodiments, the probe can be connected to the tray pick-and-place mechanism via a cable, and / or the probe can be connected to the tray fixation and release mechanism via a cable.

[0040] In some embodiments, the probes and springs are typically made of wear-resistant conductive materials (such as gold-plated copper) to withstand frequent contact and sliding, thus extending the service life of the springs and probes.

[0041] Optionally, the first signal transmission unit 400 includes a support plate 401, a probe 402, and an insulating block 403. The support plate 401 is connected to the rotating unit 200, the insulating block 403 is connected to the support plate 401, and the probe 402 is connected to the insulating block 403.

[0042] In some embodiments, similarly, probe 402 can be connected to a tray pick-and-place mechanism via cable, and / or probe can be connected to a tray fixation release mechanism (not shown) via cable.

[0043] In this utility model application, the support plate 401 provides a robust mechanical support, and multiple probes 402 can be installed at intervals on the insulating block 403. The insulating block 403 can fix the position of the probes 402, reducing the offset or loosening of the probes 402 during movement. The insulating block 403 isolates each probe 402, improving the reliability of the carrier control signal transmission. The modular design (support plate-insulating block-probe) facilitates assembly and maintenance, and the number of probes can be adjusted according to the needs of multiple electrical signals.

[0044] Optionally, the second signal transmission unit 500 includes a connecting frame 501 and a spring 502, with the connecting frame 501 connected to the intermediate shaft 300 via a connecting plate.

[0045] In some embodiments, similarly, the spring 502 can be connected to a controller (e.g., a PLC controller, microprocessor controller, etc.) via a multi-channel cable. The controller outputs a tray control signal to the second signal transmission unit 500. The tray control signal (e.g., one or more electrical signals) includes one or more tray pick-up / placement signals, and / or one or more tray fixation / release signals. The tray pick-up / placement signal includes a tray pick-up signal or a tray release signal, and the tray fixation / release signal includes a tray fixation signal or a tray release signal. The elastic range of the spring 502 can be adjusted according to the contact pressure requirements. The contact method between the probe 402 and the spring 502 can be achieved through the elastic deformation of the spring.

[0046] In this utility model application, the connecting frame 501 is fixed on the intermediate shaft 300 by the connecting plate. The design of the connecting frame 501 supports the installation of multiple spring clips and can carry the transmission of control signals of the carrier plate.

[0047] In this utility model application, the connecting frame 501 can provide stable mechanical support for the spring piece 502. The spring piece 502 maintains contact with the first signal transmission unit 400 (such as a probe) through elastic deformation, ensuring the reliability of the transmission of the control signal of the carrier plate during rotation. The modular design of the connecting frame 501 and the connecting plate facilitates disassembly and replacement. If the spring piece 502 is worn too much, it can be quickly replaced, reducing maintenance time and cost.

[0048] Optionally, the connecting plate includes a connecting ring 601 and a connecting head 602, a connecting bracket 501 connecting the connecting head 602, a connecting ring 601 connecting the connecting head 602, and a connecting ring 601 connecting the intermediate shaft 300.

[0049] In this utility model application, the connecting plate includes a connecting ring 601 and a connecting head 602. The connecting ring 601 can be fixedly connected to the intermediate shaft 300. The annular structure of the connecting ring 601 ensures coaxiality with the intermediate shaft 300. The connecting head 602 connects the connecting ring 601 and the connecting frame 501, and plays a transition and support role. The connecting plate provides a fixing platform for the connecting frame 501 and the spring piece 502, provides an installation position for the spring piece 502, and ensures the transmission of the carrier control signal.

[0050] In this utility model application, the separate design of the connecting plate (connecting ring 601 and connecting head 602) and the connecting frame 501 facilitates modular assembly and disassembly, supports quick replacement or adjustment, has a simple structure, and the connecting ring 601 and connecting head 602 can be produced in a standardized manner, with low processing costs, high assembly efficiency, and is suitable for industrial applications.

[0051] Optionally, the connecting plate includes a mounting ring 801 and multiple mounting heads 802, with the connecting bracket 501 connected to the mounting heads 802, the mounting ring 801 connected to the mounting heads 802, and the mounting ring 801 connected to the intermediate shaft 300.

[0052] In this utility model application, multiple mounting heads 802 are distributed on the mounting ring 801. The multiple mounting heads 802 support the connecting frame 501 to carry multiple spring pieces 502. The spring pieces 502 are in contact with the first signal transmission unit 400 and transmit the tray control signal. This satisfies the control requirements of the tray picking and placing mechanism (suction head mechanism or gripping head mechanism) to pick up or release (i.e., put down) the tray, or the tray fixing and releasing mechanism (see below) to clamp or loosen the tray. It is suitable for tray control scenarios. The structure of the mounting ring 801 and mounting head 802 is also very simple, can be standardized for production, has low processing cost, high assembly efficiency, and is suitable for large-scale industrial applications.

[0053] Optionally, multiple first signal transmission units 400 are provided, and the multiple first signal transmission units 400 are distributed circumferentially around the intermediate axis 300; and / or, the connector 602 is one or more.

[0054] In some embodiments, a plurality of first signal transmission units 400 are evenly distributed around the intermediate shaft 300 and fixed on the rotating unit 200. The number (one or more) of connectors 602 can be adjusted accordingly. The first signal transmission units 400 are connected to the tray loading and unloading mechanism; and / or the first signal transmission units 400 are connected to the tray fixing and releasing mechanism.

[0055] In this utility model application, as the rotating unit 200 rotates, the distribution design of the first signal transmission units 400 ensures that during the rotation process, multiple first signal transmission units 400 can sequentially contact the second signal transmission unit 500 (such as the spring 502) to realize the transmission of the carrier control signal. The circumferential distribution adapts to the contact requirements of different positions.

[0056] Optionally, multiple second signal transmission units 500 are provided, and the multiple second signal transmission units 500 are circumferentially distributed around the intermediate axis 300; and / or, multiple mounting heads 802 are circumferentially distributed around the intermediate axis 300.

[0057] In this utility model application, multiple second signal transmission units 500 are evenly distributed around the intermediate shaft 300 and fixed on the connecting frame 501. When the rotating unit 200 drives the first signal transmission unit 400 (such as the probe 402) to rotate, the multiple second signal transmission units 500 can contact the multiple first signal transmission units 400 to realize the transmission of multiple disk control signals.

[0058] In this utility model application, multiple mounting heads 802 are circumferentially distributed around the intermediate shaft 300 and connected to the mounting ring 801, supporting the connecting frame 501 and simultaneously supporting the mounting of multiple spring clips. Multiple second signal transmission units 500 are circumferentially distributed to support the simultaneous transmission of multiple electrical signals, thus meeting the control requirements of multiple carriers. It should be noted that the number and distribution of the second signal transmission units 500 and the mounting heads 802 can be adjusted according to the control requirements of the carriers, and those skilled in the art do not impose any particular limitations on this.

[0059] Optionally, the signal transmission device further includes a shaft lock P, a shaft lock connecting a connecting plate and an intermediate shaft 300.

[0060] In this utility model application, the shaft lock P (e.g., RS PRO series, etc.) connects the connecting plate (such as connecting ring 601 or mounting ring 801) and the intermediate shaft 300, ensuring the relative position of the intermediate shaft 300 and the connecting plate is stable, preventing poor electrical contact due to rotation or vibration, ensuring contact between the spring 502 and the probe 402, and improving the reliability of signal transmission. The shaft lock P can be quickly locked or released through mechanical or pneumatic control, making it easy to operate and suitable for industrial automation.

[0061] Optionally, the signal transmission device further includes a pneumatic slip ring B, which is located below the connecting plate and is connected to the rotating unit 200.

[0062] In this utility model application, the pneumatic slip ring B is located below the connecting plate and connected to the rotating unit 200 to maintain the continuous transmission of the gas medium. The pneumatic slip ring B can rotate with the rotating unit 200, or it can be connected to the rotating unit via a bearing and not rotate with the rotating unit 200, to adapt to the control requirements of the carrier plate.

[0063] Optionally, the rotating unit 200 is provided with a tray fixing and releasing mechanism 700. The tray fixing and releasing mechanism 700 includes a driving part 701, a pushing part 702 and a base 703. The base 703 can accommodate the tray. The driving part 701 drives the pushing part 702 to move and fix or release the tray.

[0064] In this utility model application, the base 703 serves as a platform for receiving the carrier tray, providing support and positioning space. The drive unit 701 (e.g., a pneumatic (cylinder) drive device, an electric (electric telescopic rod) drive device) drives the push unit 702 (exemplarily, a pusher plate or pusher) to move, clamping and fixing the carrier tray to the base 703 by mechanical force, or releasing the carrier tray.

[0065] When the carrier plate moves to a certain station, the drive unit 701 is activated, and the push unit 702 applies pressure to clamp the carrier plate and fix it. When it is released, the drive unit 701 drives in the opposite direction, and the push unit 702 withdraws the pressure to release the carrier plate. The carrier plate fixing and releasing mechanism 700 receives the carrier plate control signal through the signal transmission device (including the rotating unit 200 and two signal transmission units 400 and 500). The action of the drive unit 701 realizes the fixing or releasing of the carrier plate.

[0066] Optionally, the pushing part 702 includes a right-angled part or a right-angled part with a chamfer 704, which can contact the carrier plate; and / or, the base part 703 includes a first stop part 7031 and a second stop part 7012, which are connected and perpendicular to each other, and the second stop part 7012 is provided with a slotted part 7013.

[0067] In this utility model application, the chamfer is a rounded corner, and the right-angle portion or the right-angle portion with a chamfer 704 can contact the carrier plate. In this way, the drive portion 701 is activated, and the push portion 702 applies pressure to clamp the carrier plate and keep it fixed.

[0068] In this utility model application, the first stop 7031 and the second stop 7012 are connected and perpendicular. The first stop 7031, the second stop 7012, and the right-angled portion or the right-angled portion with a chamfer 704 can jointly limit the movement of the carrier, thereby achieving stable fixation of the carrier when the pushing part 702 applies pressure to clamp the carrier. At the same time, after the carrier is released, because the second stop 7012 is provided with a slotted portion 7013, a gripping mechanism C (e.g., Figure 4 , Figure 5 The transfer tray is clamped. For example, the first stop 7031 and the second stop 7012 can both be stop plates.

[0069] Optionally, the tray carries electrical components.

[0070] In some embodiments, the electrical component may be a capacitor or an inductor, etc.

[0071] It should be noted that one or more signal transmission devices may be installed.

[0072] The working method of the signal transmission device of this utility model application is as follows:

[0073] like Figure 1 , Figure 2 , Figure 6 As shown, when a signal transmission device is working, the rotating unit 200 rotates, and when the probe 402 contacts the spring 502, the transmission of the carrier plate control signal can be realized, controlling the fixing or releasing of the carrier plate by one or more carrier plate fixing and releasing mechanisms, specifically including:

[0074] When probe 402 contacts spring 502, the controller outputs a carrier plate control signal to spring 502. The carrier plate control signal includes one or more carrier plate fixing and releasing signals.

[0075] When the carrier plate fixing release signal includes the carrier plate fixing signal, the spring 502 outputs the carrier plate control signal to the probe 402. The probe 402 transmits the carrier plate control signal to the carrier plate fixing release mechanism 700. The carrier plate fixing release mechanism 700 can work. The drive unit 701 receives the control signal and drives the push unit 702 to move. The carrier plate is fixed on the base 703 by mechanical clamping force, thus completing the fixing of the carrier plate by the carrier plate fixing release mechanism.

[0076] And / or, the carrier plate fixing release signal includes a carrier plate release signal, the spring 502 outputs a carrier plate control signal to the probe 402, the probe 402 transmits the carrier plate control signal to the carrier plate fixing release mechanism 700, the carrier plate fixing release mechanism 700 can work, drive the push part 702 to release the carrier plate, release the clamping state, and the carrier plate fixing release mechanism releases the carrier plate.

[0077] And / or, such as Figure 4 , Figure 5 As shown, when one signal transmission device (i.e., one signal transmission device simultaneously equipped with one or more tray fixing and releasing mechanisms and one or more tray picking and placing mechanisms) or another signal transmission device is working, the rotating unit 200 rotates, and when the probe 402 contacts the spring 502, the transmission of tray control signals can be realized, controlling one or more tray picking and placing mechanisms to pick up or release trays, specifically including:

[0078] When probe 402 contacts spring 502, the controller outputs a carrier control signal to spring 502. The carrier control signal includes one or more carrier pick-up and drop signals.

[0079] When the tray pick-up and drop signal includes the tray pick-up signal, the tray pick-up and drop mechanism (e.g., suction head mechanism or gripper mechanism C) can work. The tray pick-up and drop mechanism can suck or grab the tray to pick up the tray, thus completing the tray pick-up and drop mechanism's task of picking up the tray.

[0080] And / or, when the tray pick-up and drop signal includes the tray release signal, the tray pick-up and drop mechanism (e.g., suction head mechanism or gripper mechanism C) can work, and the tray pick-up and drop mechanism can release (i.e. put down) the tray, thus realizing the release of the tray. The released tray can be placed on the base 703.

[0081] When the rotating unit 200 rotates and the probe 402 and the spring 502 are not in contact, no control signal for the carrier plate is transmitted, and the carrier plate on the base 703 can rotate with the rotating unit 200.
