Description

Technical Field

[0001] The utility model relates to the field of electronic component manufacturing equipment, and particularly to an automatic disconnection block assembling machine. Background Art

[0002] As a key component for quickly changing wires and replacing test products in test equipment, the demand for disconnection blocks continues to grow in the electronic testing industry. With the rapid iteration of electronic products and the diversification of test requirements, the production technology of disconnection blocks is also constantly evolving.

[0003] In the early stage, the production of disconnection blocks mainly relied on completely manual operations. Workers needed to manually complete all processes such as placing fixed pieces, installing pins, and assembling sockets. With the expansion of production scale, some enterprises introduced semi-automatic equipment, such as pneumatic crimping devices, to improve the efficiency and consistency of certain processes. However, the overall production process still mainly relied on manual labor, with a low degree of automation.

[0004] Currently, the production process of disconnection blocks mainly includes the following steps: manually placing fixed pieces, manually assembling pins and sockets, using pneumatic equipment for crimping, and finally manually taking out the finished products. Although this production mode has made progress compared with the early stage, there are still the following technical problems: 1. The existing process can only assemble one product at a time, and the product assembly is limited to being completed within the tooling, and it is impossible to perform the step-by-step operations of pre-assembly and crimping, which severely restricts the production efficiency; 2. The instability of manual operations leads to fluctuations in product quality, making it difficult to ensure the stability and consistency of product quality, and increasing the scrap rate.

[0005] In view of the above problems, it is urgent to develop a device that can achieve full-automatic assembly of disconnection blocks to improve production efficiency, reduce the scrap rate, meet market demands, and reduce production costs. Summary of the Utility Model

[0006] The technical problem to be solved by the utility model is: to provide an automatic disconnection block assembling machine that can greatly improve the production efficiency of disconnection blocks, so as to solve the problems of low efficiency, unstable quality, and high labor costs existing in the existing disconnection block assembly process.

[0007] The technical solution adopted by the utility model to solve its technical problems is:

[0017] The finished product taking mechanism is arranged at the downstream position of the crimping mechanism and is used to take out the assembled finished products from the machine table.

[0018] Further, the fixed piece feeding mechanism includes a vibrating bowl and a clamping device. The vibrating bowl is used to orderly convey the bulk fixed pieces, and the clamping device is used to grab the fixed pieces and place them on the turntable.

Detailed implementation manners

[0036] The present utility model will be further described below in conjunction with the accompanying drawings and embodiments, but these specific implementation manners do not limit the protection scope of the present utility model in any way. Embodiment

[0037] As Figure 1-6 shown, an automatic disconnecting block assembling machine includes:

[0038] A chassis 1, serving as the external frame and protection structure of the entire device;

[0039] A workbench 2, provided on the top of the chassis 1, providing a stable installation and operation platform for each working mechanism;

[0040] A turntable 3, provided at the central position on the top of the workbench 2, for transporting and positioning the disconnecting blocks to be assembled on the turntable 3;

[0041] A fixed piece feeding mechanism 4, provided on one side of the turntable 3, for placing the fixed pieces into the tooling on the turntable 3;

[0042] A pin feeding mechanism 6, provided at the downstream position of the fixed piece feeding mechanism 4, for inserting pins into the mounting holes of the fixed pieces;

[0043] A jack feeding mechanism 7, provided at the downstream position of the pin feeding mechanism 6, for installing jacks into the corresponding mounting holes of the fixed pieces;

[0044] A material shortage detection mechanism 8, provided at the downstream position of the jack feeding mechanism 7, for detecting whether there is any missing installation of the parts installed in the previous three stations;

[0045] A crimping mechanism 9, provided at the downstream position of the material shortage detection mechanism 8, for crimping the products detected without missing parts in place;

[0046] A finished product taking mechanism 10, provided at the downstream position of the crimping mechanism 9, for taking out the assembled finished products from the machine table.

[0047] The above solution has the following advantages:

[0048] The utility model forms an efficient automatic assembly system for disconnection blocks by arranging a turntable on the workbench and successively arranging a fixed piece feeding mechanism, a pin feeding mechanism, a jack feeding mechanism, a material shortage detection mechanism, a crimping mechanism, and a finished product taking mechanism around the turntable, effectively solving the problems of low assembly efficiency and unstable quality of disconnection blocks, and significantly improving the production efficiency and product quality.

[0049] In this embodiment, the fixed piece feeding mechanism 4 includes a vibrating plate 41 electrically connected to the electric control system and a cylinder clamping device 42. The vibrating plate 41 conveys the bulk fixed pieces in an orderly manner, and the cylinder clamping device 42 precisely grabs the fixed pieces conveyed by the vibrating plate 41 and places them into the tooling on the turntable 3. Specifically, the vibrating plate 41 is arranged on a placement rack, including a vibrating motor at the bottom and a material placement plate arranged on the vibrating motor. One side of the material placement plate is the discharge port. The cylinder clamping device 42 is arranged near the discharge port, used to grab the fixed pieces output from the discharge port and accurately place the fixed pieces on the turntable 3.

[0050] In this embodiment, the turntable 3 adopts a high-precision indexing structure, which can precisely control the rotation angle to ensure accurate positioning between each working station. Specifically, a turntable driving mechanism is provided at the bottom of the turntable 3. The turntable driving mechanism is a high-precision servo motor equipped with a high-resolution encoder, which can achieve a positioning accuracy at the micron level. And, a plurality of disconnection block carriers 5 dedicated to positioning the disconnection blocks to be assembled are arranged on the turntable 3. Each disconnection block carrier 5 includes: a positioning groove 51 for accurately placing and fixing the fixed piece of the disconnection block to ensure the accuracy of subsequent assembly steps; a pin guiding hole 52, which corresponds precisely to the mounting hole on the fixed piece, facilitating the accurate insertion of the pin; a jack positioning mechanism 53 for assisting the installation of the jack to ensure the precise fit of the jack with the fixed piece and the pin; and an elastic fixing mechanism 54, which reliably fixes each component during the assembly process and can be easily released when the finished product is taken out.

[0051] In this embodiment, the pin feeding mechanism 6 includes a vibrating plate 61 for arranging and conveying the bulk pins in an orderly manner; a conveying track 62 connected to the vibrating plate 61 for conveying the orderly pins to a designated position; a gripper 63 for grabbing the pins. The gripper 63 adopts a pneumatic jaw structure and can precisely grab two pins at the same time; it also includes X, Y, and Z-axis servo motors for controlling the movement of the gripper 63. The X-axis and Y-axis are used for positioning in the horizontal plane, and the Z-axis controls the insertion depth in the vertical direction. The vibrating plate 61 conveys the pins to the designated position, the gripper 63 precisely grabs two pins, then moves to above the fixed piece under the control of the servo motor, and subsequently the Z-axis servo motor controls the gripper 63 to descend to insert the pins into the pin guiding hole 52.

[0052] In this embodiment, the jack feeding mechanism 7 adopts precise positioning and pressing techniques to ensure the tight fit of the jacks with the fixing plates and the pins. Specifically, the jack feeding mechanism 7 includes a magazine 71 for storing the jacks to be installed, a conveying channel 72 for transporting the jacks from the magazine 71 to the working area, a robotic arm 73 with a multi-axis joint structure, and a fixture 74 installed at the end of the robotic arm 73 for gripping the jacks. A vacuum adsorption system is integrated inside the fixture 74 to ensure firm gripping of the jacks. The conveying channel 72 transports the jacks to the designated position. The multi-axis robotic arm 73 controls the fixture 74 to grip the correct jacks and then moves to the fixing plates. Subsequently, the robotic arm 73 presses down to press the jacks into the fixing plates.

[0053] In this embodiment, the material shortage detection mechanism 8 adopts optoelectronic detection technology, including multiple optoelectronic sensors and a signal processing system. Specifically, the material shortage detection mechanism 8 includes multiple sets of transmitters-receivers, which detect the products from different positions. Each set of optoelectronic sensors includes a transmitter and a receiver. The light beam emitted by the transmitter is received by the receiver after passing through the area to be detected. The signal processing system uses a high-speed microprocessor, which can analyze the signal changes of the optoelectronic sensors in real time and quickly identify whether there is a shortage or mixing of parts.

[0054] The arrangement of the optoelectronic sensors corresponds to the positions of the parts to be detected. For example, when detecting whether the fixing plates are installed in place, a set of optoelectronic sensors is installed above the expected positions of the fixing plates; when detecting whether the pins and jacks are correctly installed, multiple sets of optoelectronic sensors are arranged at the corresponding detection points, ensuring the detection coverage of each key component. To ensure the correct signal transmission between the optoelectronic sensors, both the disconnect block carrier and the turntable are provided with tiny light-transmitting holes, facilitating the arrangement of the optoelectronic sensors below the turntable corresponding to the material shortage detection mechanism.

[0055] The signal processing system collects the analog signals of the optoelectronic sensors through a high-speed A / D converter and converts them into digital signals for processing. The system adopts a threshold comparison algorithm. By comparing the intensity of the received optical signal with a preset threshold, it determines whether a part exists. For example, when detecting pins, a reflective optoelectronic sensor is used. When the pins are correctly installed, more light will be reflected back to the receiver. The signal processing system compares the received light intensity with the preset threshold to determine whether the pins exist. When detecting jacks, a transmissive optoelectronic sensor is used. When the jacks are not correctly installed (or missing), the light beam will directly pass through the detection area. When the jacks are correctly installed, part of the light beam will be blocked. In addition, by analyzing the timing relationship of the signals of different sensors, the system can also identify possible mixing problems. Optoelectronic detection technology is widely used in inspection and identification equipment. Those skilled in the art can reproduce it through the description, so it is not elaborated with drawings here.

[0056] The material shortage detection mechanism 8 is connected to the central control system. Once a material shortage or material mixing problem is detected, it immediately sends an alarm signal to the central control system. The central control system then stops the production line and displays specific error messages on the operation interface, facilitating quick positioning and problem-solving by the operators.

[0057] In this embodiment, the crimping mechanism 9 adopts a controlled crimping device, which can accurately crimp each component in place, ensuring the assembly quality and stability of the product. Specifically, the crimping mechanism 9 includes a crimping platform, a crimping head, and a servo motor; the crimping platform is fixed on the workbench 2 and is used to support the disconnection block component to be crimped. The crimping head is connected to the output shaft of the servo motor and can move in the vertical direction. The servo motor is connected to the central control system 11 through a servo driver, and controls the displacement and pressure of the crimping head according to a preset program. This type of crimping mechanism belongs to conventional technology, and those skilled in the art can reproduce it by reading and combining the existing technology, so no drawings are elaborated here.

[0058] In this embodiment, the finished product taking mechanism 10 adopts a flexible manipulator design, which can accurately position and gently grasp the finished product, avoiding any damage to the product during the material taking process. Specifically, the finished product taking mechanism 10 includes a multi-joint robot arm, and a clamping arm is provided at the end of the arm. The clamping arm can adapt to products of different shapes and sizes.

[0059] The working process of the entire disconnection block automatic assembly machine is as follows: The fixed piece feeding mechanism 4 places the fixed piece into the tooling of the turntable 3; the turntable 3 rotates and conveys the fixed piece to the pin feeding mechanism 6. The pin feeding mechanism 6 inserts two pins into the mounting holes of the fixed piece at the same time; the turntable 3 rotates again, and the product reaches the jack feeding mechanism 7 to complete the installation of the jack; the product continues to rotate with the turntable 3 to the material shortage detection mechanism 8 for comprehensive detection. The qualified products enter the crimping mechanism 9 for the final crimping and fixing. Finally, the finished product taking mechanism 10 removes the assembled product from the turntable 3.

[0060] In this embodiment, the entire system is also equipped with a central control system 11. The central control system 11 is set on the top of the frame and is connected to the turntable 3, the fixed piece feeding mechanism 4, the pin feeding mechanism 6, the jack feeding mechanism 7, the material shortage detection mechanism 8, the crimping mechanism 9, and the finished product taking mechanism 10 through a bus, and is specifically responsible for coordinating the work of each mechanism to achieve fully automated operation. The operator only needs to set parameters through the control panel and monitor the production process.

[0061] The disconnection block automatic assembly machine of the present utility model not only solves the problems existing in the prior art, but also innovates and optimizes in many aspects, reduces manual intervention, and significantly improves the production efficiency and quality of the disconnection block.

[0062] The above are only the preferred embodiments of the present utility model, and do not limit the protection scope of the present utility model. Any innovative improvement or replacement based on the present utility model shall fall within the scope of the claims of the present utility model. At the same time, the various parameters, materials, and processes mentioned in the above embodiments are not unique either. Without departing from the technical essence of the present utility model, those of ordinary skill in the art can make various alternative selections, and these alternative solutions should also be regarded as falling within the protection scope of the present utility model.
