Description

Technical Field

[0001] This utility model relates to the field of connector technology, specifically to an automatic assembly machine for 3M20P connectors. Background Technology

[0002] As an important electronic component, the 3M20P connector is widely used in various electronic devices. Its assembly quality and production efficiency directly affect the performance and production cost of electronic devices. With the rapid development of the electronics industry, the market demand for 3M20P connectors is increasing, and the requirements for production efficiency and product quality are also becoming more stringent.

[0003] The common assembly method for 3M 20P connectors often adopts a step-by-step operation mode. In this mode, each assembly step is relatively independent. After completing one assembly process, the semi-finished product needs to be transferred to the next workstation for subsequent operations by manual labor or simple transfer equipment, which is cumbersome. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an automatic assembly machine for 3M20P connectors, which has advantages such as improved production efficiency and solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic assembly machine for MP connectors, comprising a machine base and a vibratory feeder. The machine base is provided with a guide rail, a feeding mechanism, a positioning mechanism, an upper and lower row terminal feeding mechanism, a terminal insertion mechanism, a terminal folding mechanism, a terminal shaping mechanism, a product tube counting mechanism, an inkjet marking machine, an empty tube storage mechanism, and a tube pushing mechanism along the rail.

[0006] The vibratory feeder is used to transport plastic parts.

[0007] Guide rails are used for the initial guidance of plastic parts conveyed from the vibratory feeder;

[0008] The feeding mechanism is used to feed plastic parts;

[0009] The positioning mechanism is used to position plastic parts;

[0010] The upper and lower row terminal feeding mechanism is used to feed the upper and lower rows of terminals respectively;

[0011] The terminal insertion mechanism is used to insert the upper and lower rows of terminals into the pre-positioned plastic parts;

[0012] The terminal folding mechanism is used to fold the residual material strip of the terminal after it has been inserted into the plastic part;

[0013] The terminal shaping mechanism is used to correct the shape of the terminals after they have been inserted and folded.

[0014] The empty tube storage facility is used to store empty TUB tubes;

[0015] The product entry counting mechanism is used to push assembled products into the TUB tube.

[0016] Furthermore, the discharge port of the vibratory feeder corresponds to one end of the guide rail.

[0017] The above solution achieves a seamless transition of materials from the vibratory feeder to the guide rail through structural optimization, reducing positional deviations during the transfer process and improving overall conveying efficiency and stability.

[0018] Furthermore, the upper and lower terminal feeding mechanism includes two feeding discs fixedly mounted on the base surface, both of which are driven by an external motor.

[0019] The above solution enables the dual-feed tray independent drive structure to support synchronous or asynchronous feeding of upper and lower rows of terminals. The quick-change module adapts to different terminal specifications, significantly reducing equipment downtime for adjustment.

[0020] Furthermore, the product inlet counting mechanism includes a pusher cylinder and a counting sensor fixedly installed on the empty pipe storage mechanism.

[0021] The above solution, through the combined use of a pusher cylinder and a counting sensor, monitors the product pushing status in real time. By linking the pusher cylinder with the control, it ensures that the number of products in each TUB tube is accurate.

[0022] Furthermore, the empty pipe storage mechanism includes a track and a combined cylinder.

[0023] Using the above method, the combined cylinder can push the terminal into the TUB tube, thereby realizing the assembly of the two.

[0024] Furthermore, the terminal insertion mechanism includes a terminal insertion cylinder.

[0025] The above method allows the insertion cylinder to push the terminal into the track, thereby switching the terminal delivery track.

[0026] Furthermore, the terminal folding strip mechanism includes a punching cylinder, and a punching tool is fixedly installed at the output end of the punching cylinder.

[0027] The above scheme combines the use of punching tools and punching cylinders to achieve instantaneous cutting and separation of residual material strips from terminals.

[0028] Furthermore, the terminal shaping mechanism includes a crimping cylinder.

[0029] The above method uses pneumatic pressure to shape the inserted terminal, ensuring that the shaped terminal and the plastic part form an interference fit.

[0030] Compared with the prior art, the technical solution of this utility model has the following beneficial effects:

[0031] This MP connector automatic assembly machine, through the coordinated use of a vibratory feeder, a feeding mechanism, and a positioning mechanism, can transport and position plastic parts to facilitate subsequent work. The feeding mechanism accurately feeds the parts at a fixed rhythm, while the positioning mechanism fixes the position of the plastic parts, providing a foundation for subsequent processes such as terminal insertion. Combined with the terminal folding and shaping mechanism, the terminal folding mechanism quickly cuts off any residual terminal material, preventing it from interfering with the product and ensuring a clean product appearance and smooth subsequent processes. The terminal shaping mechanism uses pneumatic pressure to shape the terminals, eliminating minor deformations during insertion and ensuring a good interference fit between the terminals and the plastic parts. Finally, the product counting mechanism accurately pushes the assembled products into the TUB tubes and counts them precisely, ensuring the consistency of the number of products in each TUB tube.

[0042] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0043] Please see Figure 1 , Figure 2 and Figure 3 The 3M20P connector automatic assembly machine in this embodiment includes a machine base 1 and a vibratory feeder 2. The machine base 1 is equipped with a guide rail 3, a feeding mechanism 4, a positioning mechanism 5, an upper and lower row terminal feeding mechanism 6, a terminal insertion mechanism 7, a terminal folding tape mechanism 8, a terminal shaping mechanism 9, a product tube counting mechanism 10, an inkjet marking machine 11, and an empty tube storage mechanism 12 in sequence along its length.

[0044] Vibratory feeder 2 is used to transport plastic parts.

[0045] The guide rail 3 is used to initially guide the plastic parts conveyed from the vibratory feeder 2.

[0046] The feeding mechanism 4 is used to feed plastic parts. The feeding is achieved through indirect drive of the motor, ensuring that the feeding rhythm is synchronized with the subsequent processes.

[0047] The positioning mechanism 5 is used to position the plastic parts and can fix the terminals, thereby facilitating subsequent processing of the terminals.

[0048] The upper and lower row terminal feeding mechanism 6 is used to feed the upper and lower rows of terminals respectively. The upper and lower row terminal feeding can transport the terminals simultaneously or separately, which facilitates subsequent terminal processing. The terminal insertion mechanism 7 is used to insert the upper and lower row terminals into the pre-positioned plastic parts;

[0049] The terminal folding strip mechanism 8 is used to fold the residual strip of the terminal after it has been inserted into the plastic part, and the terminal cutting strip mechanism can bend the pins of the terminal.

[0050] The terminal shaping mechanism 9 is used to correct the shape of the terminals after they have been inserted and folded. It uses pneumatic pressure to precisely shape the terminals and eliminate minor deformations that occur during the insertion process.

[0051] The empty tube storage mechanism 12 is used to store empty TUB tubes.

[0052] The product entry counting mechanism 10 is used to push assembled products into the TUB tube.

[0053] The discharge port of the vibratory feeder 2 corresponds to one end of the guide rail 3. Through structural optimization, a seamless transition of material from the vibratory feeder 2 to the guide rail 3 is achieved, reducing positional deviation during the transfer process and improving overall conveying efficiency and stability. The upper and lower terminal feeding mechanism 6 includes two feeding discs 601 fixedly mounted on the base surface. Both feeding discs 601 are driven by external motors. The independent drive structure of the dual feeding discs 601 supports synchronous or asynchronous feeding of upper and lower terminals. Through the quick-change module, different specifications of terminals can be adapted, significantly shortening the equipment downtime for adjustment. The product inlet counting mechanism 1... The device includes a pusher cylinder 101 and a counting sensor 102 fixedly installed on the empty tube storage mechanism 12. The counting sensor 102 is a high-precision through-beam photoelectric sensor that detects the product passing through by changing the beam on / off state at the transmitting and receiving ends. It is suitable for accurate counting of transparent or opaque plastic parts, and has the ability to resist ambient light interference and a long lifespan design. By setting the pusher cylinder 101 and the counting sensor 102 to work together, the product pushing status is monitored in real time. Through the linkage control with the pusher cylinder 101, the number of products in each TUB tube is ensured to be accurate.

[0054] The empty tube storage mechanism 12 includes a track 1201 and a combination cylinder 1202. The combination cylinder 1202 can push the terminal into the TUB tube, thereby assembling the two. The terminal insertion mechanism 7 includes a terminal insertion cylinder 701. The insertion cylinder 701 can push the terminal into the track 1201, thereby switching the terminal conveying track 1201. The terminal folding strip mechanism 8 includes a punching cylinder 801. The output end of the punching cylinder 801 is fixedly installed with a punching tool 802. The combined use of the punching tool 802 and the punching cylinder 801 can realize the instantaneous cutting and separation of the residual material strip of the terminal. The terminal shaping mechanism 9 includes a crimping cylinder 901, which uses pneumatic pressure to shape the inserted terminal to ensure that the shaped terminal and the plastic part form an interference fit.

[0055] The working principle of the above embodiment is as follows: First, the vibratory feeder 2 conveys the plastic parts to the guide rail 3 through vibration, and the material feeding mechanism 4 at one end of the guide rail 3 intermittently conveys the plastic parts on the rail. After the plastic parts pass the positioning mechanism 5, the plastic parts are positioned and arranged in an orderly manner. The feeding tray 601 can convey the terminals to the guide rail 3. Then, the insertion cylinder 701 can push the terminals into the plastic parts to assemble them. When the terminals pass the terminal bending strip mechanism 8, the punching cylinder 801 can push the punching tool 802 to bend the terminals. Then, the product is conveyed to the terminal shaping mechanism 9, and the terminals are shaped by the pressing cylinder 901. Then, the pushing cylinder 101 can push the product into the track 1201 in the empty tube storage structure, and the quantity is recorded by the technical sensor. Finally, the combination cylinder 1202 can push the product to be combined with the TUB tube.
