Description

Technical Field

[0001] The present application relates to the field of connector production equipment, and in particular to a variable pitch pin insertion machine. Background Art

[0002] A connector is a component used to connect two or more electronic devices and transmit current or signals. The basic function of a connector is to provide a reliable circuit connection to ensure that electrical signals or power can be effectively transmitted from one end to the other.

[0003] In related technologies, such as Figure 1 The connector shown includes a housing 5, on which three rows of pins 62 are arranged. Each row of pins 62 is divided into three groups. The pins 62 of each row and each group have the same structure. There are intervals between the groups of pins 62 in the same row, so that the intervals between the pins 62 in the same row are different.

[0004] like Figure 2 A material strip 6 shown in the figure includes a side strip 61 and a pin 62 connected to the side strip 61 at one end. The side strip 61 is provided with transmission holes 63, and the transmission holes 63 are evenly distributed along the length direction of the side strip 61. A connecting strip 64 is provided between adjacent pins 62, and the connecting strip 64 connects two adjacent pins 62. The pins 62 are evenly distributed along the length direction of the material strip 6, that is, the spacing between adjacent pins 62 is consistent.

[0005] Since the pins 62 used in the three rows of pins 62 on the housing 5 have the same structure, they are all connected to the same sideband 61. The spacing between adjacent pins 62 on the sideband 61 is consistent, while the spacing between pins 62 in the same row on the housing 5 is different, resulting in that the pins 62 on the material strip 6 cannot be directly installed in groups on the housing 5 according to the arrangement on the sideband 61, and often need to be installed one by one, resulting in low assembly efficiency, which needs to be improved. Summary of the invention

[0006] In order to improve the installation efficiency of pins, the present application provides a variable pitch pin insertion machine.

[0007] The variable pitch pin insertion machine provided in this application adopts the following technical solution:

[0008] A variable pitch pin insertion machine, comprising

[0009] Material belt transmission mechanism: used to transmit the material belt;

[0010] Pin punching mechanism: used to separate the pin from the side band and the pin from the connecting band;

[0011] The distance-adjustable pre-clamping mechanism comprises a pre-clamping component and a distance-adjustable component for driving the pre-clamping component to move, wherein the pre-clamping component comprises a pre-clamping seat, a pre-clamping block arranged on the pre-clamping seat, and a plurality of pre-clamping sliders slidably arranged on the pre-clamping seat, wherein each of the pre-clamping sliders is arranged along the arrangement direction of the pins, and a pre-clamping driving source is arranged on the pre-clamping seat corresponding to the pre-clamping slider, and each of the pre-clamping driving sources is used to drive different pre-clamping sliders to move;

[0012] Pin installation mechanism: used to transfer the pins clamped on the distance adjustment pre-clamping mechanism to the housing;

[0013] The material tape transmission mechanism is used to transmit the material tape along the arrangement direction of the pins, and the material tape transmission mechanism can transmit the material tape to the pin punching mechanism.

[0014] By adopting the above technical solution, when the pins are installed on the housing, the material belt is first transmitted to the pin blanking mechanism through the material belt transmission mechanism. Then the pre-clamping assembly driven by the distance adjustment assembly moves to align with the pre-clamping slider and the corresponding pins, and then the pre-clamping slider aligned with the pins to be clamped is driven by the pre-clamping driving source to move in the direction close to the pre-clamping block, and the pins to be clamped are clamped by the pre-clamping slider and the pre-clamping block, and then the pin blanking mechanism disconnects the clamped pins from the side belt and the connection belt, thus completing the blanking and clamping of the first group of pins.

[0015] Before punching the second group of pins, first drive the pre-clamping assembly to move through the distance adjustment assembly, and at the same time, transfer the subsequent material tape to the pin punching mechanism through the material tape transmission mechanism. The pre-clamping assembly moves until the pre-clamping block that has not clamped the pin moves to align with the pin to be clamped, and the pre-clamping block that has clamped the pin drives the clamped pin to move to adjust the distance between the clamped pin and the pin to be clamped. Then, the pin can be clamped again through the clamping band of the corresponding pre-clamping block, and the connection between the pin and the side band and the connecting band can be separated through the pin punching mechanism. This reciprocating process can complete the punching and clamping of each group of pins until the punching and clamping of the required row of pins on the shell are completed.

[0016] Such an arrangement can achieve the clamping after adjusting the distance between the pins, so that the pins arranged at different intervals can be installed in groups together, effectively improving the installation efficiency of the pins.

[0017] Optionally, the pin punching mechanism includes a punching seat, a main punch, multiple sub-punches and a punching drive assembly for driving the main punch and the sub-punches to move. The punching seat is provided with a main hole corresponding to the main punch, and the main hole is used for inserting the main punch. The punching seat is provided with sub-holes corresponding to each sub-punch, and the sub-holes are arranged at intervals along the arrangement direction of the pins, and each sub-hole is used for inserting a different sub-punch. The material strip transmission mechanism can transmit the side strip between the main hole and the main punch, and the material strip transmission mechanism can also transmit the connecting strip between the sub-hole and the sub-punch.

[0018] By adopting the above technical solution, when punching the pin, the material strip is first transported to the pin punching mechanism through the material strip transmission mechanism, and the connecting strip of the pin to be punched is aligned with the secondary hole, and the material strip part connected to the pin to be punched is moved between the main hole and the main punch. Then, the pin separated from the material strip and the connecting strip is clamped by the distance adjustment pre-clamping mechanism, and finally, the main punch is driven to insert into the main hole and the secondary punch is driven to insert into the corresponding secondary hole by the punching drive assembly, and the main punch will punch off the part of the side strip connected to the clamped pin, and the secondary punch will punch off the connecting strip connected to the clamped pin.

[0019] Such arrangement enables the connection strip and the side strip to be punched out simultaneously, resulting in a compact structure and high punching efficiency.

[0020] Optionally, the hole wall of the main hole includes a punching wall, and the intersection of the punching wall and the surface of the punching seat on which the main hole is opened is a punching edge. When one of the connecting bands is aligned with any of the secondary holes, one of the transmission holes is staggered with the punching edge in the punching direction of the main punch.

[0021] By adopting the above technical solution, when the material strip is transferred and the connecting strip is aligned with any auxiliary hole, one of the transfer holes is staggered with the punching direction of the punch along the cutting edge. In this way, when the pin punching mechanism is punching, not only can the auxiliary punch smoothly punch the connecting edge, but also the punching part of the main punch on the side strip is the part where the transfer hole is provided on the side strip. Compared with the rest of the side strip, the part where the transfer hole is provided on the side strip has a smaller cross-sectional area along the punching direction of the main punch, which reduces the punching force required for punching. When the main punch is driven by a cylinder for punching, such a setting can reduce the cylinder diameter and increase the punching operation speed, thereby improving the assembly efficiency of the connector.

[0022] Optionally, the pin mounting mechanism includes a mounting seat, multiple groups of clamping components arranged on the mounting seat, and a clamping drive component that drives the mounting seat to move, the clamping component is used to clamp the pin, the clamping component includes a clamping block and a clamping drive source, the clamping block is hinged on the mounting seat, one end of the clamping block is used to clamp the pin with the mounting seat, and the clamping drive source is used to drive the other end of the clamping block to swing.

[0023] By adopting the above technical solution, after the pins are arranged in a row, the clamping drive source drives the clamping block to rotate until one end of the clamping block is separated from the mounting seat and a gap is generated. Then the mounting seat is driven to move by the clamping drive assembly so that the pin is inserted into the gap between the corresponding clamping block and the mounting seat. Then the clamping drive source drives the clamping block to rotate so that the clamping block and the mounting seat clamp the pin. Finally, the clamping drive source drives the mounting seat to move so that the pin moves to the position to be installed.

[0024] Optionally, the pin installation mechanism also includes a clamping rotating assembly arranged on the clamping driving assembly, the clamping driving assembly is used to drive the clamping rotating assembly to move, and the mounting seat is arranged on the clamping rotating assembly and driven to rotate by the clamping rotating assembly.

[0025] By adopting the above technical solution, after the clamping assembly cooperates with the mounting seat to clamp the pin, the mounting seat is driven to rotate by the clamping rotation assembly, which can drive the pin to rotate, thereby realizing the change of the installation direction of the pin, so as to facilitate the installation of the pin, the punching of the material strip, and the pre-clamping of the pin. For example, when the material strip is transmitted, the stability and reliability of horizontal transmission and vertical punching are much greater than vertical transmission and horizontal punching. When installing the pin, it is vertically inserted into the shell for installation. Compared with the horizontal insertion of the shell for installation, the horizontal insertion of the shell also requires the shell to be fixed or limited, that is, the pin is installed vertically, and the required device structure is simpler. The mounting seat can rotate, which expands the selection of installation angles for the pin and the selection of transmission and punching directions of the material strip, which is helpful for the production of connectors.

[0026] Optionally, the clamping rotating assembly includes a rotating shaft rotatably arranged on the clamping driving assembly, a rotating gear arranged on the rotating shaft, a rotating rack meshing with the rotating gear, and a rotating driving source driving the rotating rack to move, and the rotating rack is slidably arranged on the clamping driving assembly.

[0027] By adopting the above technical solution, when the mounting seat is driven to rotate, the rotating rack is driven to slide by the rotating driving source, thereby driving the rotating gear to rotate, and finally the mounting seat is rotated by the rotating shaft. Not only is the structure simple and easy to implement, but the control is also precise, and it is especially easy to realize 90° rotation of the mounting seat, such as realizing rotation from horizontal to vertical.

[0028] Optionally, the pin installation mechanism also includes a pin seat for placing the shell, the pin seat is provided with a pin hole for inserting the pin, and the mounting seat, the multi-clamping assembly and the clamping drive assembly are used to insert the pin into the pin hole.

[0029] By adopting the above technical solution, compared with installing the pins row by row on the shell, the first aspect involves the setting of the transfer structure of the shell, the second aspect involves the setting of the fixing structure of the shell, and the third aspect is easily affected by the shell. For example, if there are defective products in the shell without holes or holes that are not opened correctly, it will affect the operation of the entire device. By setting a pin holder, opening pin holes corresponding to the holes on the shell, the arranged pins are first inserted into the pin holes of the pin holder, and then the shell is put on the pin holder so that all the pins are inserted into the corresponding holes on the shell. Not only can the structure of the overall connector assembly equipment be effectively simplified, but the influence of the shell yield on the assembly production can also be avoided as much as possible. The arranged pins can be assembled at one time, which can improve the assembly efficiency.

[0030] Optionally, the pin installation mechanism also includes a base and an ejection assembly arranged on the base, the pin seat is slidably arranged on the base along the extension direction of the pin hole, the ejection assembly includes an ejection seat arranged on the base and an ejection block arranged corresponding to the pin hole, each of the ejection blocks is arranged on the ejection seat, each of the ejection blocks is slidably arranged in a different pin hole and is used to push the pin out of the pin hole.

[0031] By adopting the above technical solution, after the pin is installed on the pin seat, the housing is placed on the pin seat, and then the pin seat is driven to move toward the ejection seat by a driving source such as a cylinder, and the ejection block pin seat moves, that is, the ejection block slides in the pin hole. As the ejection block moves, the ejection block presses on the pin and pushes the pin out of the pin hole, so that the pin is inserted into the corresponding hole on the housing. This arrangement further improves the installation efficiency of the pin.

[0032] Optionally, the pin installation mechanism further includes a reset assembly, the reset assembly includes a reset elastic member, and the reset elastic member drives the pin seat to reset in a direction away from the ejection seat.

[0033] By adopting the above technical solution, when the pin seat moves toward the ejection seat, the reset elastic member is compressed to store energy. After the pin is installed in the housing, the reset elastic member is restored to release energy to push the pin seat to reset, so that the subsequent pin can be installed in the pin hole.

[0034] Optionally, the material belt transmission mechanism includes a positioning assembly and a material belt driving assembly, the positioning assembly includes a positioning seat, a positioning rod slidably set on the positioning seat, and a positioning driving source for driving the positioning rod to move along the extension direction of the transmission hole, the end of the positioning rod is used to insert into the transmission hole, and the material belt driving assembly is used to drive the positioning seat to move along the pin arrangement direction.

[0035] By adopting the above technical solution, when the material belt is transmitted, the positioning rod is first driven by the positioning drive source to move until the end of the positioning rod is inserted into one of the transmission holes. Then the positioning seat is driven by the material belt drive assembly to move along the pin arrangement direction, and the positioning seat drives the material belt to move along the pin arrangement direction through the push rod, so that the material belt moves along the pin arrangement direction. After the material belt is moved, the positioning rod is first driven by the positioning drive source to reset until the end of the positioning rod moves out of the transmission hole, and then the positioning seat is reset by the material belt transmission assembly. In this way, the material belt can be transmitted.

[0036] In summary, the present application includes at least one of the following beneficial technical effects:

[0037] 1. Before punching the pins, first clamp the pins to be punched through the distance-adjusting pre-clamping mechanism. After the pins are separated from the side band and the connecting band, move the clamped pins through the distance-adjusting pre-clamping mechanism to adjust the distance between the clamped pins and the subsequent pins to be punched, and move the pre-clamping slider used to clamp the subsequent pins to be clamped to align with the clamping pins of the subsequent band. Repeat this process to achieve punching and clamping of each group of pins after distance adjustment until the punching and clamping of a row of pins required on the housing are achieved, thereby achieving group installation of pins arranged at different distances, effectively improving the installation efficiency of the pins;

[0038] 2. By adjusting the relative positions of the main hole and the auxiliary hole when they are opened, and correspondingly setting the main punch and the auxiliary punch, the connecting belt is punched off, and the transmission hole on the side belt is used as the punching position to be punched. This can reduce the punching force required for punching and increase the service life of the equipment. When the cylinder is used as the punching drive source, the punching efficiency can also be effectively improved;

[0039] 3. The setting of the pin holder enables each pin to be pre-installed on the pin holder so that they can be assembled to the housing together later, effectively improving assembly efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

Then, the pre-clamping seat 311 is driven to move in the direction close to the punching seat 21 through the yield driving source 322, so that the pins are relatively moved to between the corresponding pre-clamping slider 313 and the pre-clamping block 312. Then, the pre-clamping slider 313 is driven to move by the corresponding pre-clamping driving source 314, so that the pre-clamping slider 313 and the pre-clamping block 312 clamp the corresponding pins. After the pin punching mechanism 2 completes the punching, the pre-clamping assembly 31 is driven to move by the distance adjustment driving source 321, so that the pre-clamping slider 313 located in the second group in the material belt transmission direction is aligned with the corresponding pins, and the distance between the clamped pins and the pins to be clamped is adjusted at the same time. In this way, the pins with different spacings can be arranged and clamped in rows.

This reciprocating process can complete the installation of each row of pins. After all the pins are installed, the shell is sleeved on the pin seat 46. By moving the pin seat 46 downward, the ejection assembly 48 moves relative to the pin seat 46, and the ejection block 482 pushes the pins into the shell. As the ejection block 482 continues to move, the pin drives the shell to separate from the pin seat 46.

[0075] The implementation principle of a variable pitch pin insertion machine in the embodiment of the present application is as follows: before assembling the pins and the housing, the material belt is first transferred to the desired position through the material belt transmission mechanism 1, and then the pins to be clamped are clamped by the distance adjustment pre-clamping component 31, and the corresponding pins are punched by the pin punching mechanism 2 to separate the corresponding pins from the side band and the corresponding pins from the connecting band. Then the clamped pins are driven to move and adjust the distance by the distance adjustment pre-clamping component 31, and then the subsequent pins are clamped and punched by the pin punching mechanism 2, and this process is repeated so that the distance adjustment pre-clamping mechanism 3 completes the arrangement and clamping of a row of pins. The arranged pins are clamped by the pin installation mechanism 4, and the pins are installed in the corresponding pin holes 461 on the socket by the clamping drive component 41, the mounting seat 42, the clamping rotation component 43 and the clamping component 44. After the pin installation is completed, the housing is installed on the pin seat 46, and the pins are completely installed on the housing by the ejection component 48, and the housing and the pin seat 46 are separated.

[0076] Such an arrangement enables pins with different spacings to be installed on the housing in groups, thereby improving the installation efficiency of the pins.
