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

[0032] Embodiment 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 part of the housing 1 is provided with a moving through slot 4 which vertically penetrates the bottom wall of the housing 1, and the front middle lower part of the housing 1 is provided with an L-shaped through slot 3 which horizontally penetrates the front side wall of the housing 1. Figure 3 As shown, a plurality of connecting rods 7 are arranged in parallel on the right side of the inner cavity of the shell 1, and the lower ends of the connecting rods 7 pass through the movable through slots 4 and are provided with a clamping mechanism 8 for temporarily fixing the pins, a driving mechanism 2 6 for controlling the simultaneous left and right movement of the plurality of connecting rods 7 is arranged on the left side of the inner cavity of the shell 1, and a driving mechanism 1 5 for controlling the up and down movement of the plurality of connecting rods 7 is arranged on the right side of the inner cavity of the shell 1;

[0034] It can be seen 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 the BTB connector can be used in various electronic devices such as mobile phones, computers, cameras and even medical equipment, but the size of various devices is different, the space for accommodating the connector is also different. Devices such as mobile phones and cameras require a smaller pin spacing to achieve high-density connection. Therefore, this embodiment provides a driving mechanism 6 to increase the application range of the device;

[0036] Specifically, 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, a plurality of moving components 61 for limiting the position of the connecting rod 7 are provided in the middle of the support frame 62, and a U-shaped limiting plate 63 is provided at the front right end and the rear right end of the support frame 62. Figure 5 As shown, the left and right parts of the U-shaped limiting plate 63 are both 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 a plurality of 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, 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 only the U-shaped limit plate 63 in the driving mechanism 2 6 can move up and down by relying on the extension and retraction 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 plurality of limit grooves in the guide groove group 66 are different, but the plurality of limit grooves in the same group are inclined in the same direction, and the tops and bottoms of the plurality of limit grooves are at the same horizontal height. It can be imagined that the limit grooves are placed on a plane, but their tops and bottoms are "attached" to two parallel horizontal edges of the plane, and the top spacing of each two adjacent limit grooves in the guide groove group 66 is equal, and the bottom spacing of each two adjacent limit grooves in the guide groove group 66 is equal;

[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 that 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, and the two adjacent limit grooves in the guide groove group 66 satisfy the proportional relationship of L1*sinθ1 / L2*sinθ2=L1*cosθ1 / L2*cosθ2, so that the distance between each two adjacent limit grooves in the guide groove group 66 on any horizontal line is equal, and further, when the driving mechanism 2 6 controls the plurality of connecting rods 7 to move left and right, the distance between each two adjacent connecting rods 7 in the plurality of connecting rods 7 is always equal;

[0040] Specifically, 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 equipped with rollers at the connection position 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 located 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 located on the same side and is slidably connected to the connecting rod 7, and a rubber sleeve 614 is provided at the middle part of the upper end of the right part of the horizontal part of the T-shaped connecting plate 613. 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 movable components 61 approach or move away from each other, thereby proportionally changing the spacing between two adjacent connecting rods 7 and pins.

[0042] In a standard BTB connector design, in order to ensure good electrical connection and mechanical stability, pins on the same connector are usually designed to have the same insertion depth, so that the contact pressure between each pin and the corresponding jack can be uniform and consistent, thereby improving the reliability of the connection. However, in some special BTB connector designs, in order to meet specific functional requirements, the insertion depth of some pins may be different from that of other pins. For example, for a connector with special signal transmission requirements, some pins may need to be inserted to a specific depth to achieve the best signal transmission performance. Therefore, in this embodiment, a driving mechanism 5 is provided to achieve the special depth requirement;

[0043] Specifically, Figure 7As shown, the driving mechanism 1 5 includes a moving push plate 52, an upper front end portion of the moving 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 storage slot 54 is provided at the lower left end of the moving push plate 52, as shown in FIG. Figure 8 As shown, a movable slot 1 is provided at the left portion of the bottom wall of the storage slot 54 and vertically penetrates the lower end and the left end of the movable push plate 52 for allowing the connecting rod 7 to move left and right, an open slot 510 is provided at the middle and upper portion of the movable push plate 52 and horizontally penetrates the side wall of the movable push plate 52, and a movable slot 2 is provided at 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 slide 511 are provided on the inner side of the opening groove 510, and the convex portion of the magnetic convex movable slide 511 is slidably connected in the groove of the concave slide 55, the width of the magnetic convex movable slide 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, the convex portion of the magnetic convex movable slide 511 is sleeved on the outer side of the screw 57 and is threadedly connected with the screw 57, the right part of the inner cavity top wall of the shell 1 is provided with an electric push rod 2 51, 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, and the rear inner side of the shell 1 A Z-shaped carrier plate is provided on the wall, and a stepper motor 59 is provided on the upper end of the horizontal part of the Z-shaped carrier plate. The rear end of the screw rod 57 passes through the side wall of the concave slide plate 55 and is provided with a belt-connected transmission box assembly 58 together with the output end of the stepper motor 59. 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 moving push plate 52 moves up and down. This is a simple combination of existing technologies, so it will not be 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 Fig. 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 storage slot 54, so that after pressing a single connecting rod 7 to move downward, the connecting rod 7 can be pulled back to its original position by magnetic force;

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

[0046] As can be seen from the above, when the pins need to be inserted to the same depth, the electric push rod 2 51 extends to push the movable push plate 52 downward, and then the movable push plate 52 uses the storage 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 adjustment 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. Then 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:

[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, and then the U-shaped limiting plate 63 uses the movable limiting rod 612 to slide in the limiting groove to make the multiple moving components 61 close to each other, so as to change the distance between two adjacent connecting rods 7 in proportion according to the size of the injection molding box, so that the pins can be aligned with the holes on the injection molding box later, and then the driving mechanism 1 5 controls the multiple connecting rods 7 to move up and down at the same time, and uses the clamping mechanism 8 to clamp the pins from the raw material container;

[0051] If the pins need to be inserted to the same depth, the drive 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 stepper 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] Embodiment 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. Fig. 9As shown, the clamping mechanism 8 includes a box body 81 fixedly connected to the bottom of the connecting rod 7, a connecting port vertically penetrating the side wall of the box body 81 is opened in the middle of the bottom wall of the box body 81, and right-angled trapezoidal clamping blocks 83 are provided at the left and right parts of the inner cavity of the box body 81. 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, reduce the friction between the pins, and scratch the pin surface, 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 Fig.10 As shown, the upper parts of the ends of the two right-angled trapezoidal clamping blocks 83 close to each other are both provided with mounting grooves 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 grooves 84 are located at the left part of the right-angled trapezoidal clamping blocks 83. When the two right-angled trapezoidal clamping blocks 83 are placed face to face, one of the mounting grooves 84 is located at the left part of the right-angled trapezoidal clamping blocks 83, and the other mounting groove 84 is located at the right part of the right-angled trapezoidal clamping blocks 83. Fig. 9 The placement position in can be obtained by rotating one of the right-angled trapezoidal clamping blocks 83 by 180°. The top and bottom walls of the two mounting grooves 84 are both provided with inclined grooves 87. The angle between the inclined grooves 87 and the horizontal line is 45°. The inner sides of the two mounting grooves 84 are both provided with push-pull plates 86 and limiting plates 88, and the two limiting plates 88 are located between the two push-pull plates 86. The push-pull plates 86 and the limiting plates 88 on the same side are slidably connected. The upper and lower ends of the limiting plates 88 are both provided with sliding rods near the push-pull plates 86, and the two sliding rods are respectively slidably connected in the inclined grooves 87 on the same side. A spring 2 85 is commonly provided between the end of the push-pull plate 86 away from the limiting plate 88 and the inner wall of the mounting groove 84. The limiting 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:

[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 use the inclined surface at the bottom of the two right-angled trapezoidal clamping blocks 83 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.

[0058] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, and these changes and improvements all fall within the scope of the present invention to be protected.
