Description

Technical Field

[0001] The invention relates to the technical field of connectors, and in particular to a connector automatic assembly welding plate process. Background Art

[0002] A connector is a device that connects two active devices and transmits current or signals. The male end and the female end can transmit information or current after contact, which is also called a connector. Connectors are indispensable components in electronic devices. Connectors are widely used in various electronic devices, mainly playing the role of current or signal transmission, and taking on the task of current or signal transmission. Pin and female headers are a common electronic connector and are widely used in various fields. Pin and female headers can be used for internal connections of various electronic devices, and can be used for various board-to-wire connections. Pin and female headers can be used in various field wiring in the industrial field.

[0003] In the prior art, the assembly of pin and socket headers mostly relies on manual labor. Some people hold the plastic parts manually, and then install the pin or socket terminals one by one into the plastic parts. This is not only labor-intensive but also inefficient. The operator may accidentally injure his hands or damage the product during the assembly process, and the quality of the assembly is difficult to control. Some people assemble the pin and socket headers by jigs. Although the efficiency and quality control have been improved, it still requires a lot of manpower and the efficiency is not high enough. With the increasing requirements for efficiency and quality, more and more connectors are produced using automated equipment for automatic assembly. However, the assembly process of pin and socket headers includes multiple steps. Most of the existing equipment can only automatically assemble one or several steps. Some steps require manual adjustment and assistance. Manual assisted adjustment will affect efficiency, and manual operation has no error-proofing mechanism and is prone to mistakes.

[0004] Therefore, it is necessary to provide a connector automatic assembly welding board process that can improve production efficiency and improve yield. Summary of the invention

[0005] The object of the present invention is to provide a connector automatic assembly welding plate process which can improve production efficiency and yield.

[0006] To achieve the above object, the present invention provides a connector automatic assembly welding plate process, comprising the following steps:

[0009] The terminal strip is automatically loaded onto the automatic assembly device through the strip loading device;

[0010] S3, cutting the terminal strip into a preset length by an automatic assembly device, pushing the cut material segment into a plastic fixing seat, and causing waste material on the material segment to fall off by the automatic assembly device, thereby forming a product with multiple contact terminals; and then shaping the multiple contact terminals on the product into a connector by the automatic assembly device;

[0060] In order to explain the technical content and structural features of the present invention in detail, further description is given below in combination with the implementation modes and the accompanying drawings.

[0061] See also Figures 1 to 12 The present invention provides a connector automatic assembly welding plate process 100, comprising the following steps:

[0062] S1, provide a plastic fixing seat 210, a terminal strip and a PCB board 300.

[0063] S2, automatically loading the plastic fixing seat 210 onto the automatic assembly device through the first vibration plate, and positioning the plastic fixing seat 210 on the automatic assembly device.

[0064] The terminal strips are automatically loaded onto the automatic assembly device through the strip loading device.

[0065] S3, the terminal strip is cut into a preset length by an automatic assembly device, and the preset length can be any suitable length that is convenient for automatic material pushing and installation, or the preset length is an installation length that matches the plastic fixing seat 210. Then the cut material segment 220 is pushed into the plastic fixing seat 210, and the waste material 222 on the material segment 220 is removed by the automatic assembly device to form a product with multiple contact terminals 221. The multiple contact terminals 221 on the product are then shaped by the automatic assembly device to form a connector 200.

[0066] S4, the connector 200 is inspected by a first inspection device, which is a CCD inspection device. The connector 200 that passes the inspection by the CCD inspection device enters the next process from the qualified product channel to prepare for welding with the PCB. The connector 200 that fails in appearance, size or contact terminal 221 is removed from the unqualified channel and reworked.

[0067] S5, the PCB board 300 is transferred to the welding device by the transfer device. The welding device is used to leak solder paste at a preset position on the PCB board 300, and the preset position is a position on the PCB board 300 for mounting the connector 200.

[0068] S6, the connector 200 is picked up by the first material taking device onto the soldering device, and the connector 200 is placed on a preset position of the PCB board 300. Then the PCB board 300 with the connector 200 is subjected to high temperature reflow soldering, and the solder paste on the PCB board 300 is softened by the high temperature to solder the connector 200 and the PCB board 300 together, and the circuit board product 1000 is obtained after cooling.

[0069] After adopting the above technical scheme, the connector automatic assembly welding board process 100 of the present invention realizes the automatic assembly and molding of the contact terminal 221 and the plastic fixing seat 210, and can automatically weld the molded connector 200 and the PCB board 300, with a high degree of automation, high efficiency and good assembly effect. The plastic fixing seat 210 is loaded through the first vibration disk, and the contact terminal 221 is in the form of a terminal material strip and is loaded in the form of a coil through a material strip loading device. Since the contact terminal 221 is pre-molded on the terminal material strip, when winding, a paper tape is wound together with the terminal material strip at the same time, and the paper tape can separate two adjacent circles of the terminal material strip to prevent the terminal material strips from being entangled with each other and affecting the discharge. The terminal strip is automatically cut into material segments 220 on the automatic assembly device, and then the material segments 220 are pushed and installed in the plastic fixing seat 210, and the material segments 220 are operated so that the waste material 222 on the material segments 220 installed in the plastic fixing seat 210 falls off, and multiple contact terminals 221 are installed in the plastic fixing seat 210. It can be understood that the multiple contact terminals 221 of the plastic fixing seat 210 can be divided into one material segment 220 according to actual installation needs, and installed in the plastic fixing seat 210 at one time; or divided into multiple material segments 220, and installed in the plastic fixing seat 210 multiple times. After each material segment 220 is installed in the plastic fixing seat 210, the waste material 222 can be dropped off, and then other material segments 220 can be installed, and finally a product with multiple contact terminals 221 is formed. Alternatively, after the material segments 220 in the same row of mounting holes 211 are installed, the waste material 222 is removed, and then other material segments 220 are installed in other rows of mounting holes 211, and then the waste material 222 is removed. Finally, the multiple contact terminals 221 on the connector 200 are bent and shaped to form the connector 200. In addition, the solder paste is pre-printed on the PCB board 300 according to a certain position distribution, and then the connector 200 that has passed the inspection is placed on the position where the solder paste is printed on the PCB board 300. The PCB board 300 on which the connector 200 is placed is then reflow soldered, and after the solder paste is softened at high temperature and cooled again, the PCB board 300 and the connector 200 are in an integrated structure. The connector automatic assembly soldering plate process 100 of the present invention has a high degree of automation, high efficiency, and good assembly effect.

[0070] Preferably, the automatic assembly device includes at least one positioning mechanism, at least one cutting mechanism and at least one pushing mechanism. Among them, a material trough for transmitting the terminal material strip is provided on one side of the positioning mechanism, and the material trough is connected to the material strip feeding device. The cutting mechanism is movably arranged above the material trough, and is used to cut the terminal material strip in the material trough. The pushing mechanism is arranged on the side of the material trough away from the positioning mechanism, and is used to push the cut material segment 220 into the plastic fixing seat 210, so as to install the material segment 220 in the plastic fixing seat 210. Among them, the first vibration plate drives the plastic fixing seat 210 to automatically feed the material to the positioning mechanism of the automatic assembly device, and the positioning mechanism positions the plastic fixing seat 210 at a position that matches the material segment 220, and makes the mounting hole 211 of the plastic fixing seat 210 face the material trough, so as to be installed in cooperation with the material segment 220.

[0071] See also Figures 5 to 10 In some optional embodiments, step S3 specifically includes the following steps:

[0072] The terminal strip is driven to be transferred to the positioning mechanism in the material slot by the strip feeding device, and then the terminal strip is cut into material segments 220 according to the preset length by the cutting mechanism. In this embodiment, the terminals on the material segment 220 are installed in cooperation with the mounting holes 211 on the odd positions or the mounting holes 211 on the even positions in the plastic fixing seat 210. That is, after the contact terminal 221 on a material segment 220 is installed in the plastic fixing seat 210, a mounting hole 211 is left between two adjacent contact terminals 221. Then another material segment 220 is installed in the adjacent mounting hole 211. Such a structure can better enable the contact terminal 221 to be transferred in the form of a strip, and the efficiency is higher. Of course, according to the actual installation situation, the material segment 220 can be installed once to install all the mounting holes 211 on the same row with the contact terminals 221. Specifically, after the terminal strip is cut into the material segment 220, the material segment 220 is pushed into the plastic fixing seat 210 in the positioning mechanism by the pushing mechanism.

[0073] Preferably, the automatic assembly device further comprises a first material taking mechanism, which may be a manipulator. In addition, each material segment 220 is provided with a plurality of contact terminals 221, and the plastic fixing seat 210 is provided with a plurality of mounting holes 211 for mounting the contact terminals 221, and the plurality of mounting holes 211 are arranged in one row, two rows or more rows on the plastic fixing seat 210.

[0074] See also Figures 5 to 10In some optional embodiments, step S3 specifically further includes the following steps: when there is one row of mounting holes 211, the waste material 222 can be removed after all mounting holes 211 are installed with contact terminals 221. When there are two rows of mounting holes 211, the material segment 220 can be pushed into the corresponding mounting holes 211 in the plastic fixing seat 210 by the material pushing mechanism. Then the plastic fixing seat 210 is moved horizontally to a certain position by the first material taking mechanism, and other material segments 220 are continuously pushed into other corresponding mounting holes 211 in the plastic fixing seat 210 by the material pushing mechanism, and then the waste material 222 is folded. That is, after a whole row of mounting holes 211 are installed with contact terminals 221, the waste material 222 is removed. Of course, one material segment 220 can also be installed to remove the waste material 222 once. After completing the installation of the contact terminals 221 in a row of mounting holes 211, the first material-picking mechanism is used to flip the plastic fixing seat 210 up and down in the positioning mechanism, so that the positions of the first row of mounting holes 211 and the second row of mounting holes 211 are swapped, and then the material segment 220 is pushed into the corresponding mounting hole 211 in the plastic fixing seat 210 by the material-pushing mechanism. Then the plastic fixing seat 210 is moved horizontally to a certain position by the first material-picking mechanism, and other material segments 220 are continuously pushed into other corresponding mounting holes 211 in the plastic fixing seat 210 by the material-pushing mechanism, and then the waste material 222 is folded and the insertion is completed to form a product with multiple contact terminals 221. The displacement of the plastic fixing seat 210 can also be transmitted by setting a transmission mechanism on the frame. In this embodiment, there are two rows of mounting holes 211, and the terminals of one row of mounting holes 211 are pre-assembled, and then the position is adjusted and the terminals of the other row of mounting holes 211 are assembled.

[0075] See also Figures 5 to 10 In some other optional embodiments, the automatic assembly device includes multiple positioning mechanisms, multiple cutting mechanisms and multiple pushing mechanisms. Step S3 specifically also includes the following steps: pushing the material segment 220 into the corresponding mounting hole 211 in the plastic fixing seat 210 through the pushing mechanism, and then folding the waste material 222. Then, the first material picking mechanism or the conveying mechanism on the frame is used to make the plastic fixing seat 210 pass through multiple positioning mechanisms in sequence to complete the insertion of multiple contact terminals 221 in the plastic fixing seat 210, thereby forming a product with multiple contact terminals 221. It can be understood that in this embodiment, the insertion of each material segment 220 is completed by different positioning mechanisms, cutting mechanisms and pushing mechanisms, and different connectors 200 can be assembled at the same time, which is more efficient.

[0076] Preferably, the automatic assembly device further comprises a material folding mechanism, and the material folding mechanism is provided with a card slot. Figures 5 to 10In some optional embodiments, step S3 specifically further includes the following steps: the plastic fixing seat 210 with the material section 220 installed is transferred to the material folding mechanism, the contact terminal 221 in the material section 220 is inserted into the plastic fixing seat 210, and one end of the material section 220 with the waste material 222 is inserted into the card slot. Then the waste material 222 on the material section 220 is dropped by swinging the card slot. It can be understood that the end of the contact terminal 221 that cooperates with the mounting hole 211 can be elastically movable, and can facilitate guiding the contact terminal 221 into the mounting hole 211. When the contact terminal 221 is installed in the mounting hole 211 of the plastic fixing seat 210, the contact terminal 221 elastically abuts against the mounting hole 211, and the structural connection is stable. The plastic fixing seat 210 is positioned on the material folding mechanism, and the plastic fixing seat 210 can be positioned by a positioning member wrapped with a rubber sleeve. At this time, the end of the waste material 222 extends into the slot and swings up and down with the slot, so that the waste material 222 is separated from the contact terminal 221, and the contact terminal 221 and the plastic fixing seat 210 are elastically contacted in the left and right directions, and the up and down swinging can less shake the contact terminal 221 and the plastic fixing seat 210. The structure is simple, the operation is convenient, and it will not affect the cooperation between the contact terminal 221 and the plastic fixing seat 210.

[0077] Preferably, the automatic assembly device further comprises a shaping mechanism. After the plurality of contact terminals 221 are installed in the plastic fixing seat 210, a first terminal row 201 and a second terminal row 202 are formed, and each contact terminal 221 has a bending portion 223 that matches the PCB board 300. Figure 7 and Fig.10, step S3 specifically also includes: conveying the product to the shaping mechanism, and sending the first terminal row 201 and the second terminal row 202 in the first direction through the shaping mechanism, so that all the contact terminals 221 in the plastic fixing seat 210 are in the same direction in the plastic fixing seat 210, and then bending the first terminal row 201 and the second terminal row 202 in the second direction. The second direction is opposite to the first direction, and the second direction is the direction of the contact terminal 221 bending. It can be understood that the contact terminal 221 is pre-prepared with a material strip for bending on the terminal strip, and the material strip can be pre-bent in the direction to be bent. In the process of inserting the contact terminal 221 and removing the waste material 222, the material strip may be touched, so that the bending angles of the material strips on each contact terminal 221 are not uniform. If the bending is performed directly at this time, it will affect the bending molding effect. Therefore, the material strip can be pre-sent in another direction by a pusher and other components to make the bending angles of each material strip uniform, and then the material strip is bent to form a bending portion 223. Among them, the first terminal row 201 and the second terminal row 202 are symmetrically arranged on the plastic fixing seat 210 and bent to both sides respectively. The first terminal row 201 and the second terminal row 202 can be cut and bent respectively, or the first terminal row 201 and the second terminal row 202 can be cut and bent at the same time.

[0078] Preferably, the automatic assembly device further comprises a second material taking mechanism and an assembly station, and the connector 200 further comprises a suction cap 230. Fig.11 , step S3 specifically includes: transferring the connector 200 to the assembly station through the conveying structure on the automatic assembly device and positioning it on the assembly station. The connector 200 can also be picked up to the assembly station by a robot. In addition, the suction cap 230 is automatically fed to the assembly station through the second vibration disk, and then the suction cap 230 is picked up by the second material picking mechanism and inserted into the connector 200. The provision of the suction cap 230 makes it easier to pick up the entire connector 200 with a suction cup without damaging the appearance of the connector 200. The suction cap 230 is provided with a snap-fitting portion 231, which can be snap-fitted onto the plastic fixing seat 210. A guide portion 232 is provided at one end of the snap-fitting portion 231, and the guide portion 232 can facilitate the snap-fitting and insertion of the snap-fitting portion 231 onto the plastic fixing seat 210.

[0079] See also Fig.12, step S5 specifically includes: multiple PCB boards 300 are stacked on a rack, and a conveying device is connected to the rack and can convey the PCB boards 300 on the rack to the welding device one by one. The leakage position is set in advance according to actual requirements, and the PCB board 300 is leaked on the welding device. Then, in the following step, the connector 200 is placed at the position where the solder paste is leaked, and the cooled solder paste is hot-melted by reflow soldering, so that the connector 200 and the PCB board 300 are welded together, and then cooled to obtain the circuit board product 1000.

[0080] See also Fig.12 In some optional embodiments, step S6 is followed by step S7: the circuit board product 1000 is laser scanned by a laser on a laser detection device to detect whether the connector 200 on the PCB board 300 is soldered in place. If there is a leak, rework is required, and if it passes the inspection, it flows into the next process.

[0081] After step S6, the method further includes step S8: using a second material taking device to pick up the circuit board product 1000 to the automatic packaging machine, and then using the automatic packaging machine to automatically wrap and package the circuit board product 1000.

[0082] like Figures 1 to 12 As shown, the connector automatic assembly welding process 100 of the present invention realizes the automatic assembly and molding of the contact terminal 221 and the plastic fixing part, and can automatically weld the molded connector 200 and the PCB board 300. It has a high degree of automation, high efficiency and good assembly effect. The plastic fixing seat 210 is loaded through the first vibration plate, and the contact terminal 221 is in the form of a terminal strip and is loaded through a strip loading device. The terminal strip is automatically cut into material segments 220 on the automatic assembly device, and then the material segment 220 is pushed and installed in the plastic fixing seat 210, and the material segment 220 is operated so that the waste material 222 on the material segment 220 installed in the plastic fixing seat 210 falls off. Finally, the multiple contact terminals 221 on the connector 200 are bent and shaped to form the connector 200. In addition, the solder paste is pre-printed on the PCB board 300 according to a certain position distribution, and then the connector 200 that has passed the inspection is placed on the position of the PCB board 300 where the solder paste is printed and needs to be connected with the connector 200. The PCB board 300 with the connector 200 is then reflowed, and the solder paste is softened at high temperature and then cooled again to form a circuit board product 1000 with an integrated structure of the PCB board 300 and the connector 200. The connector automatic assembly soldering board process 100 of the present invention has a high degree of automation, high efficiency, and good assembly effect.

[0083] The above disclosure is only a preferred embodiment of the present invention, which cannot be used to limit the scope of the present invention. Therefore, equivalent changes made according to the claims of the present invention are all within the scope of the present invention.
