A mobile communications rig

Abstract

This application relates to a mobile communication fixture for carrying a workpiece and moving it along a feeding direction. It includes a fixture plate, an actuator disposed within a space on the fixture plate, several receiving antennas, and a controller. The fixture plate has a bearing surface for carrying the workpiece. The actuator applies force to restrain the workpiece when the fixture moves to a preset position. The receiving antennas are disposed within the space and are respectively arranged on the upstream and downstream sides of the feeding direction. The controller is connected to the receiving antennas and the actuator, and controls the actuator to operate after receiving a control signal from the receiving antennas. This mobile communication fixture, because the receiving antennas are distributed upstream and downstream in the feeding direction and participate in the control logic determination together with the controller, effectively solves the signal reception blind spot problem caused by metal structure obstruction in the prior art, thereby achieving stable communication and precise control in complex interference environments and ensuring the reliability of the fixture's response during movement.

Description

Technical Field

[0001] This invention relates to mobile tooling, and more particularly to a mobile communication tooling. Background Technology

[0002] In fields such as automated assembly, semiconductor manufacturing, and precision electronic product processing, mobile tooling is typically used in conjunction with conveyor systems to transport and position workpieces in order to improve production line efficiency and achieve standardized operations. This type of mobile communication tooling not only carries the workpiece but also interacts with external control systems to automate operations at specific workstations. Therefore, tooling equipment with communication capabilities and precise, controlled responses has become an indispensable component in today's automated production environments.

[0003] Existing mobile tooling structures typically include: a tooling plate for placing the workpiece, an embedded actuator (such as an electromagnetic lock or cylinder), and a receiving antenna for receiving control signals. In practical applications, after the tooling moves to different workstations along the feeding direction, it activates the actuators based on the received wireless control signals to complete workpiece positioning, fixing, or other operations.

[0004] However, in actual production line layouts, the widespread presence of metal frames, supports, and shielding structures (such as tracks and metal enclosures) can lead to signal reception blind spots or interference areas for some receiving antennas during tooling operation. This is especially true during movement in the feeding direction, where signal continuity and integrity are difficult to guarantee, thus affecting the accuracy of the actuators' response. Therefore, there is an urgent need to propose a mobile communication tooling to solve these problems. Utility Model Content

[0005] The purpose of this invention is to provide a mobile communication fixture with a reasonable structural design that can effectively reduce the signal shielding effect of metal structures.

[0006] The technical solution adopted by this invention to solve the above problems is: a mobile communication tooling for carrying a workpiece and moving in a controlled manner along a feeding direction, comprising: A tooling plate, including a receiving space, wherein one side of the tooling plate is a bearing surface for bearing a workpiece; An actuator is disposed within the accommodating space. The actuator operates under control to apply a force to the workpiece placed on the bearing surface when the mobile communication tooling is moved to a preset position, thereby confining the workpiece on the bearing surface. A receiving antenna is disposed within the accommodating space to receive external control signals. The number of the receiving antennas is several, and at least one receiving antenna is respectively provided on both the upstream and downstream sides of the accommodating space near the feeding direction. A controller is disposed within the accommodating space and is connected to the actuator and the receiving antenna. The controller is configured to control the actuator to operate after the receiving antenna receives a control signal.

[0007] Preferably, the receiving antennas located within the accommodating space and respectively disposed on the upstream and downstream sides near the feeding direction have a preset distance between their orthogonal projections in the first direction, which is defined as perpendicular to the feeding direction.

[0008] Preferably, the number of the execution units is several.

[0009] Preferably, the tooling plate has a first opening slot communicating with the accommodating space and a second opening slot communicating with the accommodating space at the bearing surface, the receiving antenna portion passing through the first opening slot and the execution portion passing through the second opening slot.

[0010] Preferably, the actuator is an electromagnet, which is configured to apply a magnetic attraction force to the workpiece placed on the bearing surface when the mobile communication tool moves to a preset position, so as to fix the workpiece on the bearing surface.

[0011] Preferably, the electromagnet includes an adsorption surface that passes through the second opening groove, and the adsorption surface is coplanar with the bearing surface.

[0012] Preferably, the mobile communication fixture further includes a power supply module, which is disposed in the accommodating space and connected to the controller.

[0013] Preferably, the power supply module is a carbon brush assembly, which is connected to the controller, the actuator and the receiving antenna, and the carbon brush assembly is configured to be connected to the external sliding contact line when the mobile communication tool is in working state.

[0014] The beneficial effects of the embodiments of the present invention are as follows: 1. Since at least one receiving antenna is set on both the upstream and downstream sides near the feeding direction in the accommodating space, and multiple receiving antennas are connected to the controller to participate in signal reception and control logic judgment, the signal reception blind zone problem caused by the metal frame and obstruction structure in the prior art is effectively solved. This enables stable communication and precise execution control in complex interference environments, ensuring the response accuracy and control reliability of the tooling during movement.

[0015] 2. Because a preset distance is maintained between the orthographic projections of the receiving antennas located on both the upstream and downstream sides of the accommodating space in the feeding direction, the problem of existing technologies where receiving antennas are easily placed in the same direction and simultaneously enter the signal dead zone under the action of the metal shielding structure is effectively solved. This achieves spatial offset redundancy of the signal receiving path. Specifically, when one antenna cannot effectively receive the control signal due to obstruction or directional interference, the other antenna is still located in the unshielded area at a different position, thus being able to receive the signal normally and trigger the control response. The existence of this preset distance avoids the attenuation of the synchronization signal caused by "coaxial shielding," improving the communication robustness of the control system and the continuity of tooling response in complex metal environments.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art will understand the specific meaning of the above terms in this application based on the specific circumstances.

[0023] Please see Figures 1 to 3 A preferred embodiment of this application provides a mobile communication fixture for use in automated production lines to carry workpieces and move them in the conveying direction in conjunction with the conveyor mechanism of the production line. This mobile communication fixture is suitable for typical scenarios such as precision welding, electronic component inspection, and precision structural component loading, and is particularly suitable for complex wiring environments with metal obstructions, limited space, or multiple parallel control signals.

[0024] The mobile communication fixture includes a fixture plate 10, an actuator 20, a receiving antenna 30, and a controller 40. The fixture plate 10 includes a receiving space 110, and one side of the fixture plate 10 is a bearing surface 120 for supporting a workpiece. The actuator 20 is disposed within the receiving space 110, and its controlled operation applies a force to the workpiece placed on the bearing surface 120 when the mobile communication fixture moves to a preset position, thereby confining the workpiece on the bearing surface 120. A receiving antenna 30 is disposed within the accommodating space 110 to receive external control signals. The number of receiving antennas 30 is several, and at least one receiving antenna 30 is respectively disposed on both the upstream and downstream sides of the accommodating space 110 near the feeding direction. Furthermore, the orthographic projections of the receiving antennas 30 located within the accommodating space 110 and respectively disposed on the upstream and downstream sides near the feeding direction are spaced at a predetermined distance in a first direction, which is defined as perpendicular to the feeding direction. A controller 40 is disposed within the accommodating space 110 and is connected to the execution unit 20 and the receiving antennas 30. The controller 40 is configured to control the execution unit 20 to operate after the receiving antenna 30 receives a control signal.

[0025] Specifically: The tooling plate 10 is a one-piece molded structure made of high-strength, lightweight composite material to balance structural stability and weight control. The tooling plate 10 has an internal accommodating space 110, which is a cuboid cavity used to mount the actuator 20, receiving antenna 30, and controller 40. One side surface of the tooling plate 10 is a bearing surface 120, which is horizontal on the assembly line and located on the upper surface of the tooling plate 10. It undergoes precision machining to fit the bottom surface of various structural workpieces and ensure stable support.

[0026] The actuator 20 is a power mechanism for applying force to the workpiece and is disposed within the accommodating space 110. The actuator 20 is perpendicular to the bearing surface 120. When the tooling moves to the target station or designated inspection area on the production line, it receives a control signal and causes the workpiece on the bearing surface 120 to adhere tightly to the bearing surface 120, achieving the purpose of limiting and fixing. When no signal is received or the actuator 20 is in a standby state, it remains in a retracted state to reduce workpiece interference.

[0027] Receiving antennas 30 are arranged within the accommodating space 110. There are multiple antennas in total, with at least one receiving antenna 30 positioned on each of the upstream and downstream sides along the feeding direction. This ensures that during the forward or backward movement of the tooling, there is always a receiving antenna 30 within the unobstructed receiving area. Specifically, the receiving antennas 30 on the upstream and downstream sides are spaced at a predetermined distance in the direction perpendicular to the feeding direction (i.e., the orthogonal projection in the first direction). This distance is determined based on parameters such as the control signal transmission field strength, the size of the metal obstruction, and the antenna radiation mode. This ensures that the two antennas are not completely within the same obstruction area, forming a receiving redundancy zone and significantly reducing the probability of simultaneous obstruction. The receiving antennas 30 can be low-power, wide-bandwidth patch antennas or magnetic loop antennas, encapsulated in an anti-interference material housing, and connected to the controller 40 via shielded wiring.

[0028] The controller 40 is installed within the accommodating space 110 and is electrically connected to the receiving antenna 30 and the actuator 20 via wiring. It is used to receive control signals transmitted from the antenna in real time and to perform signal recognition and action trigger determination. The controller 40 has a built-in recognition algorithm module with functions such as signal priority judgment, noise reduction, and repeated confirmation. It can judge and fuse signals from multiple antennas to ensure accurate interpretation of control signals in interference environments.

[0029] During use, when the mobile communication fixture, carrying a workpiece, enters a preset station on the production line, a signal transmitter deployed in the environment sends control commands to the fixture. Upstream and downstream antennas on the fixture receive the control signals at different spatial angles and transmit them to the controller 40. After recognizing the signal, the controller 40 triggers the execution unit 20 to perform a fixing operation on the workpiece. After this fixing is completed, the production line can continue with the next steps of inspection, processing, and sorting. It should be noted that the aforementioned preset station corresponds to a preset position. The movement of the fixture plate 10 to the preset position can be determined by sensors installed on the production line; preferably, these sensors are photoelectric sensors.

[0030] This mobile communication fixture is suitable for industrial automation workshops with indoor temperature, normal humidity, and no severe impact. It supports high-frequency repeated use and features a compact structure, high control precision, and strong anti-interference capability.

[0031] In this embodiment, since multiple receiving antennas 30 are respectively set on the upstream and downstream sides of the feeding direction, and a preset distance is reserved between the orthographic projections in the direction perpendicular to the feeding direction, and these receiving antennas 30 and the controller 40 are arranged in a coordinated manner, the problem of synchronous failure of receiving antennas 30 and interruption of communication signals caused by metal frame obstruction in the prior art is effectively solved. Thus, redundant reception and stable parsing of control signals in complex electromagnetic interference environment are realized, ensuring the accurate response of the actuator 20 and the real-time reliability of workpiece limit control.

[0032] Please see Figure 3 In some embodiments, the mobile communication fixture further optimizes the arrangement of the actuator and antenna in its structural design to improve the stability and spatial adaptability of signal transmission and reception and execution response. In this embodiment, the fixture plate 10 is an integral structure, with its top surface set as a bearing surface 120 for placing the workpiece, and below the bearing surface 120 is an accommodating space 110 with multi-layer wiring and structural support frame. The number of actuators 20 is several. The bearing surface 120 of the fixture plate 10 has a first opening slot 121 communicating with the accommodating space 110 and a second opening slot 122 communicating with the accommodating space 110. The receiving antenna 30 is partially inserted through the first opening slot 121, and the actuator 20 is partially inserted through the second opening slot 122. The actuator 20 is an electromagnet, which is configured to apply a magnetic attraction force to the workpiece placed on the bearing surface 120 when the mobile communication fixture moves to a preset position, so as to fix the workpiece on the bearing surface 120. The electromagnet includes an adsorption surface 210, which passes through the second opening groove 122, and the adsorption surface 210 is coplanar with the bearing surface 120.

[0033] Specifically: The first opening slot 121 is mainly used for the signal channel layout of the antenna assembly. Some components of the receiving antenna 30 are inserted into this slot so that part of its antenna area is close to or exposed on the surface of the tooling plate 10, thereby improving signal receiving sensitivity and avoiding the shielding effect of internal metal components. The antenna packaging structure is covered with an anti-interference polymer shell, which can effectively isolate conductive interference sources.

[0034] The second opening slot 122 is used to embed the actuator. In this embodiment, the actuator 20 consists of several electromagnet units, each disposed within the accommodating space 110 and partially inserted into the corresponding second opening slot 122, with its adsorption surface 210 being coplanar with the bearing surface 120. This coplanar design ensures uniform distribution of magnetic force when acting on the bottom surface of the workpiece, avoiding problems such as workpiece tilting or unstable positioning caused by protrusions or depressions in the adsorption surface 210. Multiple electromagnets are evenly distributed in different areas of the bearing surface 120, ensuring sufficient magnetic support coverage even with large or irregularly shaped workpieces.

[0035] During operation, once the mobile communication fixture is transported to the designated workstation, the controller 40 activates the corresponding electromagnet unit based on the control signal acquired by the receiving antenna 30. Upon power-up, magnetic force is rapidly established, and the adsorption surface 210 instantly generates an adsorption force on the bottom of the workpiece, thereby firmly fixing the workpiece to the bearing surface 120. This process has a fast response speed, requires no mechanical clamping action, and is suitable for scenarios involving frequent workstation switching or repetitive positioning.

[0036] In terms of control strategy, the controller 40 can selectively activate electromagnets in corresponding areas according to different workpiece sizes, realizing regional adsorption control, which combines the advantages of flexibility and energy consumption control. The internal control logic performs data parsing and execution judgment between the control signal reception and the electromagnet on / off state, ensuring accurate response and error-free operation.

[0037] This mobile communication fixture is suitable for applications such as positioning and conveying of workpieces to be welded and high-precision pre-assembly positioning. It can operate stably and continuously in environments with strong electromagnetic interference or metal structure obstruction, making it particularly suitable for use in high-density automated production lines.

[0038] In this embodiment, by adopting a structural approach that involves setting an opening slot at the bearing surface 120 that communicates with the accommodating space 110, and having the receiving antenna 30 and the electromagnet respectively pass through different slots, and by arranging the electromagnet's adsorption surface 210 and the bearing surface 120 in a coplanar manner, the structural interference and uneven adsorption problems caused by the stacking of internal components in the tooling in the prior art are effectively solved. This results in clearer signal reception path, improved electromagnetic adsorption stability, and enhanced workpiece positioning accuracy.

[0039] Please see Figures 1 to 3In some embodiments, to ensure a stable and continuous power supply during operation of the mobile communication fixture, a power supply module 50 is further introduced. The mobile communication fixture also includes the power supply module 50, which is disposed within the accommodating space 110 of the fixture plate 10 and sequentially connected to the controller 40, the actuator 20, and the receiving antenna 30 via internal wiring, thereby providing the necessary power support for the continuous operation of these functional components. The power supply module 50 is a carbon brush assembly, which is connected to the controller 40, the actuator 20, and the receiving antenna 30. When the mobile communication fixture is in operation, the carbon brush assembly is connected to an external sliding contact line.

[0040] Specifically: The carbon brush assembly is made of composite carbon-graphite material with excellent conductivity and encapsulated in a heat-resistant and wear-resistant housing structure, exhibiting good sliding contact performance and durability. This carbon brush assembly is fixedly mounted on the bottom or side of the tooling plate 10 and is positioned opposite to the sliding contact line structure in the external power supply system. The sliding contact line is typically arranged along the production line direction (feeding direction). When the mobile communication tooling moves along the production line, enters the target station, or is within the working area, the carbon brush assembly and the sliding contact line form a sliding contact, thereby establishing an electrical connection and forming a stable power supply path.

[0041] The carbon brush assembly has a multi-stage elastic preload mechanism (not shown in the figure) to ensure full contact with the sliding contact line at different positions, avoiding poor power contact due to mechanical vibration or sliding angle deviation. The power supply path is transmitted to the controller 40 through the carbon brush assembly, and then the controller 40 distributes the power supply to the actuator 20 and the receiving antenna 30, realizing the energy closed loop of each functional unit in the communication reception, logic operation and action response process.

[0042] This power supply structure requires no additional batteries or wireless power supply devices during operation, avoiding maintenance costs caused by battery capacity decay or frequent replacements. It also does not rely on complex inductive coupling systems. The overall structure is compact and flexible in layout, making it suitable for production line scenarios with limited space or complex electromagnetic environments.

[0043] In the control process, once the fixture is connected to the sliding contact line, the carbon brush assembly automatically receives electrical energy. The controller 40 then activates the system, begins receiving signals from the antenna 30, and responds to action commands. The entire control and power supply mechanism enables synchronous operation during continuous operation, ensuring uninterrupted communication and efficient response.

[0044] This structure is suitable for continuous feeding automated production lines, and is especially suitable for tooling systems that require long-term operation and high-frequency station switching. The system as a whole is highly adaptable to the working environment and can work stably under normal temperature and humidity conditions and mechanical vibration interference.

[0045] In some alternative embodiments, the placement of the carbon brush assembly can be adjusted according to the relative height relationship between the bottom of the fixture and the sliding contact line track, and two sets of carbon brushes can be connected in parallel to improve the load-bearing capacity according to the current requirements; the sliding contact line can also adopt a bipolar or multipolar wiring structure to adapt to different voltage or control signal path requirements.

[0046] In this embodiment, by using a carbon brush assembly as a power supply module 50 within the accommodating space 110 and establishing an electrical connection between it and the external sliding contact line when the tooling is in operation, the problem of discontinuous power supply, limited battery life, or low wireless power supply efficiency of the tooling during movement in the prior art is effectively solved. This achieves stable and continuous power supply and low-maintenance, highly reliable communication control system operation under dynamic conveying conditions.

[0047] The above description is merely illustrative of the invention. Those skilled in the art can make various modifications or additions to the described specific embodiments or use similar methods to replace them, as long as they do not depart from the content of this specification or exceed the scope defined by the claims, all of which should fall within the protection scope of this invention.
