[0031] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0032] Example 1

[0033] like Figure 1-Figure 3 As shown, this embodiment discloses a BTB connector production pin device, including a housing 1, as shown in FIG. Figure 1 As shown, the left end of the housing 1 is provided with a hydraulic rod 2 for controlling the horizontal movement of the housing 1. Figure 2 As shown, the lower right portion of the housing 1 is provided with a movable through slot 4 that vertically penetrates the bottom wall of the housing 1, and the lower middle portion of the front end of the housing 1 is provided with an L-shaped through slot 3 that horizontally penetrates the front side wall of the housing 1. Figure 3 As shown, the right part of the inner cavity of the shell 1 is provided with multiple connecting rods 7, and the multiple connecting rods 7 are distributed side by side. The lower end of the connecting rod 7 passes through the movable slot 4 and is provided with a clamping mechanism 8 for temporarily fixing the pins. The left part of the inner cavity of the shell 1 is provided with a driving mechanism 2 6 for controlling the simultaneous left and right movement of the multiple connecting rods 7. The right part of the inner cavity of the shell 1 is provided with a driving mechanism 1 5 for controlling the up and down movement of the multiple connecting rods 7.

[0034] It can be seen from this that when the equipment is working, the driving mechanism 1 5 first controls the connecting rod 7 to move downward, uses the clamping mechanism 8 to clamp the pins from the raw material container, and then controls the connecting rod 7 to reset. After that, the hydraulic rod 2 extends and pushes the shell 1 to move above the injection molding box. Then the driving mechanism 2 6 adjusts the distance between the multiple connecting rods 7 according to the size of the injection molding box to align the pins with the holes on the injection molding box. Finally, the driving mechanism 1 5 continues to control the connecting rod 7 to move downward to insert the pins into the injection molding box.

[0035] Since BTB connectors can be used in various electronic devices such as mobile phones, computers, cameras, and even medical equipment, the sizes of various devices vary, and the space required to accommodate the connectors also varies. Devices such as mobile phones and cameras require a smaller pin pitch to achieve high-density connections. Therefore, this embodiment provides a second drive mechanism 6 to increase the applicability of the devices.

[0036] Specifically, such as Figure 3 As shown, the driving mechanism 2 6 includes a support frame 62 fixedly connected to the left inner wall of the housing 1, as shown in FIG. Figure 4 As shown, the middle part of the support frame 62 is provided with a plurality of moving components 61 for limiting the position of the connecting rod 7, and the right front end and the right rear end of the support frame 62 are both provided with a U-shaped limiting plate 63, as shown in FIG. Figure 5 As shown, the left and right parts of the U-shaped limiting plate 63 are provided with guide groove groups 66, and the two guide groove groups 66 are symmetrically distributed with the vertical center line of the moving component 61 as the axis. The guide groove group 66 is composed of several limiting grooves, such as Figure 4 As shown, a T-shaped connecting baffle 64 is provided at the front right end of the U-shaped limiting plate 63, and an electric push rod 1 65 is provided at the front bottom wall of the housing 1, and the output end of the electric push rod 1 65 is fixedly connected to the horizontal part of the T-shaped connecting baffle 64;

[0037] It can be seen that in the second drive mechanism 6, only the U-shaped limit plate 63 can be moved up and down by the extension and contraction of the electric push rod 1 65, and then the guide groove group 66 is used to adjust the distance between two adjacent moving components 61;

[0038] Further, such as Figure 5 As shown, the lengths and inclination angles of the multiple limiting grooves in the guide groove group 66 are different, but the multiple limiting grooves in the same group are all inclined in the same direction, and the tops and bottoms of the multiple limiting grooves are at the same horizontal height. It can be imagined that these limiting grooves are placed on a plane, but their tops and bottoms are "attached" to two parallel horizontal edges of this plane. The tops of every two adjacent limiting grooves in the guide groove group 66 are spaced equally, and the bottoms of every two adjacent limiting grooves in the guide groove group 66 are spaced equally.

[0039] In addition, the vertical components and horizontal components of the plurality of limit grooves on any horizontal line also satisfy a specific proportional relationship. Assuming the inclination angle of the limit groove is θ and the length is L, then the component of the limit groove in the vertical direction is L*sinθ and the component in the horizontal direction is L*cosθ. The two adjacent limit grooves in the guide groove group 66 satisfy the proportional relationship of L1*sinθ1 / L2*sinθ2=L1*cosθ1 / L2*cosθ2, thereby making the distance between each two adjacent limit grooves in the guide groove group 66 on any horizontal line equal. Further, when the driving mechanism 2 6 controls the left and right movement of the plurality of connecting rods 7, the distance between each two adjacent connecting rods 7 in the plurality of connecting rods 7 is always equal.

[0040] Specifically, such as Figure 6 As shown, the moving assembly 61 includes a moving plate 611 horizontally slidably connected to the support frame 62, and the moving plate 611 can be installed with rollers at the connection part with the support frame 62 to reduce the moving friction of the moving assembly 61, and a T-shaped connecting plate 613 is provided at the bottom of the right end of the moving plate 611, and a moving limiting rod 612 is provided at the upper left end of the vertical part of the T-shaped connecting plate 613. The left end of the moving limiting rod 612 passes through the limiting groove on the same side and is fixedly connected to the moving plate 611, and the horizontal part of the right part of the T-shaped connecting plate 613 is sleeved on the outer side of the connecting rod 7 on the same side and is slidably connected to the connecting rod 7. A rubber sleeve 614 is provided at the middle part of the upper end of the right horizontal part of the T-shaped connecting plate 613, and the rubber sleeve 614 is sleeved on the outer side of the connecting rod 7 to increase the friction resistance of the connecting rod 7 moving up and down, so as to prevent the connecting rod 7 from freely falling when losing the support of the driving mechanism 5, thereby affecting the normal operation of the equipment;

[0041] From the above, it can be seen that the electric push rod 65 works by controlling the U-shaped limit plate 63 to move up and down through the T-shaped connecting baffle 64, and then the U-shaped limit plate 63 uses the movable limit rod 612 to slide in the limit groove to make the multiple moving components 61 approach or move away from each other, and proportionally change the spacing between the two adjacent connecting rods 7 and the pins.

[0042] In standard BTB connector designs, to ensure good electrical connection and mechanical stability, pins on the same connector are typically designed to have the same insertion depth. This ensures uniform contact pressure between each pin and its corresponding socket, thereby improving connection reliability. However, in some specialized BTB connector designs, to meet specific functional requirements, the insertion depth of some pins may differ from that of others. For example, in connectors with special signal transmission requirements, some pins may need to be inserted to a specific depth to achieve optimal signal transmission performance. Therefore, this embodiment provides a drive mechanism 5 to achieve this specific depth requirement.

[0043] Specifically, such as Figure 7As shown, the driving mechanism 1 5 includes a movable push plate 52, an upper front end portion of the movable push plate 52 is provided with an adjusting rod 53, the front portion of the adjusting rod 53 passes through the L-shaped through slot 3 and extends to the outside of the housing 1, and a receiving slot 54 is provided at the lower left end portion of the movable push plate 52. Figure 8 As shown, a movable slot 1 is formed on the left side of the bottom wall of the receiving slot 54 and vertically penetrates the lower and left ends of the movable push plate 52 for allowing the connecting rod 7 to move left and right. An open slot 510 is formed on the upper middle portion of the movable push plate 52 and horizontally penetrates the side wall of the movable push plate 52. A movable slot 2 is formed on the middle portion of the top wall of the open slot 510 and vertically penetrates the upper end of the movable push plate 52.

[0044] like Figure 8 As shown, a concave slide 55 and a magnetic convex movable slider 511 are provided on the inner side of the opening slot 510, and the convex portion of the magnetic convex movable slider 511 is slidably connected to the groove of the concave slide 55, and the width of the magnetic convex movable slider 511 is greater than the width of the movable slot 2. The inner cavity of the concave slide 55 is provided with a horizontally placed screw 57, and the convex portion of the magnetic convex movable slider 511 is sleeved on the outer side of the screw 57 and is threadedly connected to the screw 57. An electric push rod 2 51 is provided on the right part of the top wall of the inner cavity of the shell 1, and the output end of the electric push rod 2 51 passes through the movable slot 2 and is fixedly connected to the concave slide 55. The rear inner side of the shell 1 The wall is provided with a Z-shaped carrier plate, and the upper end of the horizontal part of the Z-shaped carrier plate is provided with a stepping motor 59. The rear end of the screw 57 passes through the side wall of the concave slide 55 and is provided with a belt-connected transmission box assembly 58 between the output end of the stepping motor 59, and the belt-connected transmission box assembly 58 is slidably connected in the open groove 510. The belt-connected transmission box assembly 58 consists of a belt transmission assembly and an outer box. The outer box is used to ensure that the belt transmission assembly will not be affected when the mobile push plate 52 moves up and down. This is a simple combination of existing technologies, so it is no longer described in detail. The belt-connected transmission box assembly 58 is fixedly connected to the upper end of the vertical part of the Z-shaped carrier plate, such as Figure 9 As shown, the upper end of the connecting rod 7 passes through the movable slot and is provided with a magnetic plate 9 slidably connected to the receiving slot 54, so that after pressing a single connecting rod 7 to move downward, the magnetic force can be used to pull the connecting rod 7 back to its original position;

[0045] In the initial state, the plurality of magnetic plates 9 are all located in the receiving slots 54;

[0046] As can be seen from the above, when the pins need to be inserted to the same depth, the second electric push rod 51 extends to push the movable push plate 52 downward, and then the movable push plate 52 uses the receiving slot 54 to push the magnetic plate 9 and the connecting rod 7 downward, so that multiple pins are inserted to the same depth at the same time;

[0047] When the depth of the pins to be inserted is no longer consistent, first move the adjusting rod 53 to the right on the outside of the shell 1 to disengage the magnetic plate 9 from the storage slot 54, then start the stepper motor 59, and control the screw 57 to rotate through the belt-connected transmission box assembly 58. Then the screw 57 controls the magnetic convex moving slider 511 to move to the top of the connecting rod 7 that needs to be moved downward. After that, repeat the above steps, and the moving push plate 52 will use the magnetic convex moving slider 511 to push the single connecting rod 7 downward to insert the pin to the expected depth.

[0048] Furthermore, the vertical parts of the magnetic plate 9 and the magnetic convex movable slider 511 are mutually attractive neodymium iron boron magnets. The magnetic force of neodymium iron boron magnets is several times or even dozens of times that of ordinary ferrite magnets. They can easily absorb objects that are dozens of times larger than their own weight. In the industrial field, neodymium magnets can also be used in tools such as magnetic clamps and magnetic lifters to conveniently and quickly transport and fix metal objects.

[0049] Therefore, the specific implementation of this embodiment is as follows:

[0050] The electric push rod 1 65 extends through the T-shaped connecting baffle 64 to control the U-shaped limiting plate 63 to move upward. Then, the U-shaped limiting plate 63 uses the movable limiting rod 612 to slide in the limiting groove to move the multiple moving components 61 closer to each other, so as to change the distance between two adjacent connecting rods 7 in proportion to the size of the injection molding box so that the pins can be aligned with the holes on the injection molding box. Then, the driving mechanism 1 5 controls the multiple connecting rods 7 to move up and down simultaneously, and the clamping mechanism 8 is used to clamp the pins from the raw material container.

[0051] If the pins need to be inserted to the same depth, the driving mechanism 5 will continue to control the connecting rod 7 to move downward and insert the pins into the injection molding box. If the depth of the pins to be inserted is no longer consistent, first move the adjusting rod 53 to the right on the outside of the shell 1 to disengage the magnetic plate 9 from the storage slot 54, and then the stepping motor 59 controls the screw 57 to rotate through the belt-connected transmission box assembly 58, and then the screw 57 controls the magnetic convex moving slider 511 to move to the top of the connecting rod 7 that needs to be moved downward, and then repeat the above steps. The moving push plate 52 will use the magnetic convex moving slider 511 to push the single connecting rod 7 downward to insert the pin to the expected depth.

[0052] Example 2

[0053] This embodiment further improves the clamping mechanism 8 on the basis of the first embodiment, so as to find out the pins that are not aligned in advance and avoid damage to the injection molding box when inserting the pins. Figure 9As shown, the clamping mechanism 8 includes a box body 81 fixedly connected to the bottom of the connecting rod 7. A communication port is provided in the middle of the bottom wall of the box body 81 and vertically penetrates the side wall of the box body 81. The left and right parts of the inner cavity of the box body 81 are both provided with right-angled trapezoidal clamping blocks 83. The right-angled trapezoidal clamping blocks 83 are made of smooth polytetrafluoroethylene, or a wear-resistant coating is applied on the surface of the right-angled trapezoidal clamping blocks 83 to reduce the friction coefficient and reduce the friction between the pins, thereby reducing the scratching of the pin surface and affecting the appearance and electrical performance of the pins. A spring 82 is provided between the ends of the two right-angled trapezoidal clamping blocks 83 that are away from each other and the inner wall of the box body 81.

[0054] Further, such as Figure 10 As shown, the upper part of one end of the two right-angled trapezoidal clamping blocks 83 close to each other is provided with a mounting groove 84, and the two mounting grooves 84 are staggered. When the two right-angled trapezoidal clamping blocks 83 are placed side by side, the mounting groove 84 is located on the left part of the right-angled trapezoidal clamping block 83. When the two right-angled trapezoidal clamping blocks 83 are placed face to face, one of the mounting grooves 84 is located on the left part of the right-angled trapezoidal clamping block 83, and the other mounting groove 84 is located on the right part of the right-angled trapezoidal clamping block 83. Figure 9 The placement position in can be obtained by rotating one of the right-angled trapezoidal clamping blocks 83 180 degrees. The top and bottom walls of the two mounting grooves 84 are provided with inclined grooves 87. The angle between the inclined grooves 87 and the horizontal line is 45 degrees. The inner sides of the two mounting grooves 84 are provided with push-pull plates 86 and limit plates 88, and the two limit plates 88 are located between the two push-pull plates 86. The push-pull plates 86 and the limit plates 88 on the same side are slidably connected. The upper and lower ends of the limit plates 88 are close to the push-pull plates 86. A sliding rod is provided, and the two sliding rods are respectively slidably connected in the inclined groove 87 on the same side. A spring 2 85 is provided between the end of the push-pull plate 86 away from the limit plate 88 and the inner wall of the mounting groove 84. The limit plate 88 is always tightly attached to the other right-angled trapezoidal clamping block 83 under the push of the push-pull plate 86 and the spring 2 85.

[0055] Furthermore, the front inner wall of one mounting groove 84 and the rear inner wall of the other mounting groove 84 are both located in the middle vertical plane of the right-angled trapezoidal clamping block 83, so that the two limiting plates 88 and the sides of the two right-angled trapezoidal clamping blocks 83 close to each other jointly form a cubic space for clamping pins.

[0056] Therefore, the specific implementation of this embodiment is as follows:

[0057] When the clamping mechanism 8 moves downward, the pins will enter the inner side of the box body 81 through the connecting port, and then the inclined surface of the lower part of the two right-angled trapezoidal clamping blocks 83 will be used to push the two right-angled trapezoidal clamping blocks 83 apart. At this time, the limiting plate 88 will also move obliquely outward under the action of the spring 2 85 and the push-pull plate 86, so that the two limiting plates 88 and the two right-angled trapezoidal clamping blocks 83 are close to each other. A cubic space for clamping the pins is formed. If the pins are in a skewed state, they cannot enter the cubic space normally, which makes it convenient for the staff to observe the condition of the pins and reduces the subsequent quality inspection process.

It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention.
