Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of connector assembly production, in particular to a connector assembly production device. BACKGROUND

[0002] The double-row pin connector is a device that uses two rows of pins for connection, which is usually composed of two parts of a detachable connector plug and a socket. One row of pins on the plug corresponds to one row of slots on the socket, and the electrical and signal transmission is achieved by inserting the plug into the socket. This design is not only simple and stable, but also can maintain reliable connection in different environments, and is also convenient for maintenance and replacement. The double-row pin connector needs to be assembled and produced by using an assembly jig during production.

[0003] For example, the Chinese patent document with the authorization announcement number CN204030245U discloses a pin connector mounting device, which includes a base, a push rod, a support rod, a rotating rod and a connecting rod. The patent sets the base for placing the base and the plurality of pins, and sets the push rod with the convex teeth cooperating with the base to slide. When operating, the rotating rod is rotated to drive the push rod to move to the right, and the convex teeth on the push rod push the pins into the inner hole of the base. Since the pushing force of the push rod on the pins is consistent, the entire row of pins can be pushed into the base at one time, and the pins are uniformly stressed.

[0004] However, the above-mentioned device still has some deficiencies when in use: the above-mentioned pin connector mounting device pushes the pins into the base by the push rod. The above-mentioned device is used for the installation of single-row pins, and only one row of pins can be inserted into the connecting seat at a time during use. To complete the installation of double-row pins, the connecting seat needs to be manually turned over after the installation of one row of pins is completed, and then the second row of pins is inserted and installed. The assembly efficiency is low. In addition, the connecting seat may change the position of the installed pins when it is turned over, thereby affecting the production quality of the connector.

[0005] In order to complete the simultaneous assembly of double-row pins, the skilled person in the same field is easy to think of setting two rows of pin slots above and below to insert two rows of pins into the connecting seat at the same time, but two difficulties need to be solved to realize this function: 1. How to quickly and accurately place the pins in the two rows of pin slots; 2. How to insert the pins in the two rows of pin slots into the connecting seat at the same time, and the existing technology cannot well solve the above problems.

[0006] Therefore, in order to improve the installation efficiency of the double-row pin connector, a connector assembly production device is needed, which can quickly and accurately place the pins in the two rows of pin slots and insert the two rows of pins into the connecting seat at the same time.

[0056] The main idea of the application is that the pin 13 can be distributed into the recesses of the upper pin receiving plate 222 and the lower pin receiving plate 221 by setting the discharging device 21, the recesses correspond to the two rows of pin holes in the connector, and then the jacking rod 34 provides a pushing force to push the upper pin receiving plate 222 and the pushing plate 23, so that the pin 13 is inserted into the corresponding pin hole of the connecting seat 12, thereby completing the assembly of the connector.

[0057] Embodiment 1 of the connector assembly production apparatus provided by the present invention:

[0058] like Figures 1 to 15 As shown, the assembly production device mainly includes a workbench 1, a drive structure 3, a discharge structure 2, and a transmission structure 4. The workbench 1 is a square plate and serves as the carrier of the device. The drive structure 3 is located on one side of the workbench 1, specifically at the left end, and provides thrust for the assembly operation. The connector includes a connector base 12 and pins 13. The discharge structure 2 is located at the right end of the workbench 1 and is used to insert the pins 13 into the connector base 12 in layers. The transmission structure 4 is located below the discharge structure 2 and is used to lift the connector after assembly.

[0059] The following section first introduces the material discharge structure 2, such as... Figure 1 As shown, the material feeding structure 2 mainly includes a feeder 21, which is a vertical plate-like structure extending front and rear. Rectangular rod-shaped supports 212 are provided on both its front and rear sides. The feeder 21 is fixed to the workbench 1 via the supports 212. Inside the feeder 21, two rows of vertical needle channels 213 are arranged linearly. The diameter of the needle channels 213 is adapted to the outer periphery of the pins 13. The needle channels 213 are through holes. The pins 13 are vertically inserted into each needle channel 213 via external equipment and enter the assembly process through each needle channel 213.

[0060] In addition, such as Figure 1 , Figure 4 and Figure 5 As shown, square cutouts 214 are provided on the left and right sides of the lower end of the feeder 21, corresponding to each needle channel 213. The width of the cutout 214 is the same as the diameter of the needle channel 213, and the square cutout 214 is connected to the arc surface of the corresponding needle channel 213. Among them, the lower ends of two adjacent cutouts 214 are connected through each other, and a stop block 215 is provided inside the two connected cutouts 214. The stop block 215 is a rectangular block, such as... Figure 9 As shown, the stop block 215 has a shaft 216 extending forward and backward inside. The shaft 216 is rotatably mounted on the feeder 21. One end of the shaft 216 is equipped with a motor 217. The motor 217 is located at the front end of the shaft 216 and is fixed on the feeder 21 so that it can drive the stop block 215 to rotate together through the shaft 216.

[0061] like Figures 11 to 15As shown, the left and right side corners of the block 215 are rounded. Since the pins 13 are vertically placed in each lower needle passage 213, when the long side of the block 215 is rotated counterclockwise from the horizontal direction to the vertical direction, the pin 13 in the left lower needle passage 213 is released downward, and the pin 13 in the right lower needle passage 213 is pushed upward by the right end of the block 215. At this time, the rounded corners can prevent the pin 13 from being clamped by the right end of the block 215. When the long side of the block 215 is in the vertical position, the pin 13 in the right lower needle passage 213 is released downward, and then slides to the right side with the rotation of the block 215. When the long side of the block 215 continues to rotate counterclockwise to the horizontal position, the upper side of the block 215 can block the pins 13 in the left and right lower needle passages 213, thereby achieving the blocking and positioning of the pins 13. By setting the motor 217 and the block 215 to optimize the discharging structure 2, the smooth discharging can be ensured, and the excess pins 13 can be prevented from falling and stacking, thereby ensuring the smoothness of the assembly process.

[0062] Secondly, as shown in Figure 1 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 , the discharging structure 2 further comprises a pin receiving plate 22, which is divided into two layers, the lower layer being a lower pin receiving plate 221. The lower pin receiving plate 221 is a rectangular block structure, is fixed on the workbench 1 and is located between the two side supports 212. The upper surface of the lower pin receiving plate 221 has a plurality of horizontally extending grooves, which correspond to the right lower needle passages 213 of the discharger 21. These grooves are defined as grooves one 2211, which are used to receive the pins 13 released by the right lower needle passages 213 of the discharger 21. The two sides of the protruding part between two adjacent grooves one 2211 have chamfers, which play a role in assisting the lower end of the pin 13 to enter the groove, thereby ensuring the smoothness of the assembly process.

[0063] The pin receiving plate 22 is divided into two layers, the upper layer being an upper pin receiving plate 222. The upper pin receiving plate 222 is a rectangular plate structure and is located above the lower pin receiving plate 221. The lower surface of the upper pin receiving plate 222 has a plurality of horizontally extending top strips, which are in sliding guide cooperation with the grooves one 2211 and are defined as top strips one 2225. The top strips one 2225 are used to push the pins 13 in the grooves one 2211 to the right.

[0064] As shown in Figure 6As shown in the figure, the upper surface of the upper needle receiving plate 222 has a plurality of horizontally extending grooves corresponding to the lower needle channels 213 on the left side of the material dispenser 21, which are defined as grooves two 2226, and are used to receive the inserted pins 13 released from the left side of the material dispenser 21. The two sides of the protruding part between the two adjacent grooves two 2226 are chamfered, which can help the lower end of the inserted pin 13 enter the groove. The right end surface of the top strip one 2225 is arranged in a staggered manner with the right end surface of the groove two 2226, which is used to prevent the lower inserted pin 13 from being pushed upward during the pushing process. Among them, as Figure 5 shown in the figure, the left end of the upper needle receiving plate 222 has two cylindrical limiting rods 2221 extending horizontally in parallel, and a pushing spring 2222 is sleeved on the limiting rod 2221, which is used to push the upper needle receiving plate 222 to move to the right.

[0065] Then, as Figure 2 shown in the figure, the material dispensing structure 2 further comprises a pushing plate 23 located above the upper needle receiving plate 222, and the lower surface of the pushing plate 23 has a plurality of horizontally extending top strips corresponding to the grooves two 2226, which are defined as top strips two 232, and are used to push the inserted pins 13 received by the upper needle receiving plate 222. As Figure 6 shown in the figure, the right end surface of the top strip two 232 is arranged in a staggered manner with the right end surface of the pushing plate 23, and when the top strip two 232 pushes the inserted pin 13 to the right, the upper end surface of the pushing plate 23 is located above the inserted pin 13, which can prevent the left end of the inserted pin 13 from being pushed upward during the pushing process.

[0066] As Figure 2 shown in the figure, the front and rear sides of the left end of the upper needle receiving plate 222 are respectively provided with square lower limiting blocks 2223, and the front and rear sides of the right end of the pushing plate 23 are respectively provided with square upper limiting blocks 231, which can push the lower limiting blocks 2223 to the left when the pushing plate 23 moves to the left, thereby driving the upper needle receiving plate 222 to move to the left.

[0067] Next, the driving structure 3 will be introduced, as Figure 1 shown in the figure, the driving structure 3 is located at the left end of the workbench 1, which comprises a cylinder 31, and the right end of the cylinder 31 is provided with a cylindrical cylinder push rod 32 extending and moving horizontally, and the right side of the cylinder push rod 32 is provided with a cylinder push plate 33, which is a rectangular block and is fixedly connected with the cylinder push rod 32. As Figure 6 shown in the figure, the right upper end of the cylinder push plate 33 is fixedly connected with the left end of the pushing plate 23, and two guide holes 35 are arranged in the middle of the cylinder push plate 33, as Figure 1 and Figure 2 shown in the figure, the two guide holes 35 are slidably connected with the two limiting rods 2221 to guide the sliding direction of the limiting rods 2221.

[0068] In addition, asFigure 1 、 Figure 2 、 Figure 4 and Figure 5 As shown in the drawings, the right end of the workbench 1 is provided with a limiting seat 11, which is a rectangular block structure, and the left end of the limiting seat 11 is fixedly connected with the lower layer of the needle plate 221. Figure 4 In the limiting seat 11, a clamping groove 112 is arranged above the limiting seat 11, and a plurality of square avoiding grooves 113 corresponding to the first groove 2211 and the second groove 2226 are arranged in the clamping groove 112. The square avoiding grooves 113 extend through the limiting seat 11 in the left-right direction, and play a guiding role in the process of inserting the pin 13 into the connector, so that the assembly process of the pin 13 is more smooth. The shape of the clamping groove 112 is matched with the outer shape of the connecting seat 12, and is used for installing the connecting seat 12. Figure 4 In the limiting seat 11, a clamping groove 112 is arranged above the limiting seat 11, and a plurality of square avoiding grooves 113 corresponding to the first groove 2211 and the second groove 2226 are arranged in the clamping groove 112. The square avoiding grooves 113 extend through the limiting seat 11 in the left-right direction, and play a guiding role in the process of inserting the pin 13 into the connector, so that the assembly process of the pin 13 is more smooth. The shape of the clamping groove 112 is matched with the outer shape of the connecting seat 12, and is used for installing the connecting seat 12.

[0069] As shown in the drawings, the right end of the workbench 1 is provided with a limiting seat 11, which is a rectangular block structure, and the left end of the limiting seat 11 is fixedly connected with the lower layer of the needle plate 221. Figure 7 As shown in the drawings, the right end of the workbench 1 is provided with a limiting seat 11, which is a rectangular block structure, and the left end of the limiting seat 11 is fixedly connected with the lower layer of the needle plate 221. Figure 5 As shown in the drawings, the right end of the workbench 1 is provided with a limiting seat 11, which is a rectangular block structure, and the left end of the limiting seat 11 is fixedly connected with the lower layer of the needle plate 221.

[0070] As shown in the drawings, the right end of the workbench 1 is provided with a limiting seat 11, which is a rectangular block structure, and the left end of the limiting seat 11 is fixedly connected with the lower layer of the needle plate 221. Figure 1 As shown in the drawings, the right end of the workbench 1 is provided with a limiting seat 11, which is a rectangular block structure, and the left end of the limiting seat 11 is fixedly connected with the lower layer of the needle plate 221. Figure 3 As shown in the drawings, the right end of the workbench 1 is provided with a limiting seat 11, which is a rectangular block structure, and the left end of the limiting seat 11 is fixedly connected with the lower layer of the needle plate 221.

[0071] As shown in the drawings, the right end of the workbench 1 is provided with a limiting seat 11, which is a rectangular block structure, and the left end of the limiting seat 11 is fixedly connected with the lower layer of the needle plate 221. Figure 3 、 Figure 7 、 Figure 8 and Figure 9 As shown in the drawings, the right end of the workbench 1 is provided with a limiting seat 11, which is a rectangular block structure, and the left end of the limiting seat 11 is fixedly connected with the lower layer of the needle plate 221.Figure 8 As shown, the upper and lower sides of the outer peripheral surface of the actuating element 45 have axially extending transmission plates 47. (As shown...) Figure 3 As shown, a wedge block 46 is in contact with the upper part of the actuating member 45. The wedge block 46 is slidably installed in the limiting seat 11 with its inclined surface facing down. During the process of the traction block 42 moving to the left, the traction block 42 pushes the transmission plate 47 on the lower side of the actuating member 45 to the left, causing the actuating member 45 to rotate clockwise around the fixed shaft 43. At this time, the transmission plate 47 on the upper side of the actuating member 45 pushes the inclined surface of the wedge block 46 to move the wedge block 46 upward, thereby lifting the connecting seat 12.

[0072] like Figure 8 As shown, a torsion spring 44 is provided between the actuating element 45 and the fixed shaft 43 to reset the actuating element 45 after rotation. The transmission structure 4 enables the cylinder push rod 32 to push out the connector 12 while retracting, reducing manual labor and preventing the pin 13 from shifting or misaligning during manual material handling, thus improving the assembly accuracy of the connector.

[0073] The working principle of the connector assembly and production apparatus provided by this invention is as follows:

[0074] Before assembly, the cylinder push rod 32 drives the cylinder push plate 33 to the left side of the workbench 1. First, the pin 13 is inserted into the lower needle channel 213 of the feeder 21. At least two pins 13 stacked on top of each other are left in each lower needle channel 213 on both sides of the feeder 21. At this time, the long side of the stop block 215 is in the horizontal direction, and the lower pins 13 in each lower needle channel 213 are blocked by the stop block 215. Then, viewed from the front, the motor 217 drives the stop block 215 to rotate counterclockwise. As the long side of the stop block 215 rotates from the horizontal to the vertical direction, the needle 13 in the needle channel 213 on the left side of the feeder 21 slides down to the left along the upper side of the stop block 215 and slides into the groove 2226 on the upper side of the upper needle receiving plate 222. The needle 13 in the needle channel 213 on the right side of the feeder 21 is pushed upward by the stop block 215. When the long side of the stop block 215 continues to rotate to the vertical direction, the needle 13 in the needle channel 213 on the right side of the feeder 21 begins to slide downward.

[0075] From the front side, in the process of the long edge of the block 215 continuing to rotate counterclockwise from the vertical direction to the horizontal direction, the remaining needle 13 in the left lower needle channel 213 of the dispenser 21 is blocked by the left end of the block 215, and the needle 13 in the right lower needle channel 213 of the dispenser 21 continues to slide right along the upper side of the block 215 and falls into the groove one 2211 on the upper side of the lower needle plate 221. When the long edge of the block 215 continues to rotate to the horizontal direction, the remaining needle 13 in the right lower needle channel 213 of the dispenser 21 is blocked by the block 215, and thus the left and right lower needle channels 213 of the dispenser 21 complete a needle 13 discharging operation.

[0076] Then the cylinder 31 is started, the cylinder push plate 33 pushes the pushing plate 23 to move to the right side, and at the same time the cylinder push plate 33 pushes the upper needle plate 222 to move to the right side through the pushing spring 2222, at this time the top bar one 2225 pushes the needle 13 in the groove one 2211 to the right side. Because the elastic force of the reset spring 111 is greater than that of the pushing spring 2222, when the upper needle plate 222 moves to the left end of the reset spring 111, the reset spring 111 pushes the block 2224 to the left, and the upper needle plate 222 stops moving, at this time the needle 13 on the lower needle plate 221 is located on the left side of the connecting seat 12.

[0077] Then the pushing plate 23 continues to move to the right side under the action of the cylinder 31, the pushing spring 2222 is squeezed, and the top bar two 232 pushes the needle 13 inside the groove two 2226 to the right side. When the two top rods 34 move to the left end surface of the upper needle plate 222, the two top rods 34 push the upper needle plate 222 to the right, so that the upper needle plate 222 moves to the right side with the pushing plate 23 at the same time, at this time the reset spring 111 is squeezed, and then in the process of the pushing plate 23 and the upper needle plate 222 moving to the right side, the needles 13 in the groove one 2211 and the groove two 2226 are pushed by the top bar one 2225 and the top bar two 232 into the needle hole inside the connecting seat 12, realizing the assembly of the needle 13 and the connecting seat 12.

[0078] After the assembly of the needle 13 is completed, the pushing plate 23 and the traction plate 41 are moved to the left side under the action of the cylinder 31, at this time the reset spring 111 pushes the right end surface of the upper needle plate 222 to the left, so that the upper needle plate 222 also moves to the left side. When the right end surface of the upper needle plate 222 moves to the left side of the connecting seat 12, the traction block 42 pushes the transmission plate 47 on the lower side of the actuator 45 to the left, so that the transmission plate 47 on the upper side of the actuator 45 rotates to the right and compresses the torsion spring 44, at this time the transmission plate 47 on the upper side of the actuator 45 pushes the inclined surface on the lower end of the wedge block 46 upward, so that the wedge block 46 moves upward, and the wedge block 46 pushes the connecting seat 12 upward, so that the connecting seat 12 is pushed out upward.

[0079] In the process of moving left with the cylinder 31 driving the pushing plate 23, the upper limit block 231 at the right end of the pushing plate 23 will push the lower limit block 2223 at the left end of the upper layer of the needle plate 222 left, thereby driving the upper layer of the needle plate 222 to move left. When the pushing plate 23 moves to the left to the stroke limit of the cylinder 31, the upper layer of the needle plate 222 also moves to the left side of the discharger 21.

[0080] In addition, in the process of moving right with the traction plate 41, the traction block 42 pushes the transmission plate 47 at the lower side of the driving part 45 right, so that the transmission plate 47 at the upper side of the driving part 45 rotates left. In this process, the transmission plate 47 at the upper side of the driving part 45 has no contact with the wedge block 46, and will not affect the assembly work of the pin 13.

[0081] In this embodiment, the two ends of the pin 13 are the same structure, and there is no distinction between positive and negative. In other embodiments, the two ends of the pin 13 are different structures, and there is a distinction between positive and negative. At this time, when the pin 13 is inserted into the discharger 21, the insertion direction of the left row of pins 13 and the right row of pins 13 needs to be opposite, so as to ensure that the direction of the pin 13 inserted into the connector is consistent.
