Description

Technical Field

[0001] This utility model relates to the field of module strips, and specifically to a module strip terminal mounting device. Background Technology

[0002] As a highly integrated micro-electronic device, hearing aids place extreme demands on the size, precision, and reliability of their internal connector components. For example, a certain hearing aid connector project requires the assembly of two types of extremely small terminals (φ1.00±0.015; φ2.08-0.022) inside the injection molding strip, followed by injection molding. The repeatability accuracy requirement is ±0.005mm; otherwise, glue overflow will occur after injection molding.

[0003] Currently, this operation is mainly accomplished using semi-automatic pressing equipment. Specifically, after the operator initially positions the terminal and the mold strip, a pneumatically or hydraulically driven press head performs the pressing action. However, in practical applications, this production method suffers from problems such as low repeatability accuracy, poor product quality consistency, low production efficiency, and high costs. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide a terminal assembly device that can press the terminal into the mold strip with high precision and with high assembly efficiency.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is: a module strip terminal assembly device, comprising: A support platform for supporting mold strips has a first station and a second station arranged side by side in a first direction; The die strip feeding mechanism is used to feed the die strip from the first station to the second station; Two mold strip precision positioning and fixing mechanisms, respectively corresponding to the mold strips at the first and second workstations, are used to precisely position and press the corresponding mold strips during the pressing process. Two terminal pressing mechanisms, respectively corresponding to the first terminal on the mold strip after precision positioning at the first station and the second terminal on the mold strip after precision positioning at the second station, are used to press the corresponding terminal into the corresponding mold strip during the pressing process.

[0006] Furthermore, the die-mounting device also includes a coarse positioning mechanism for coarsely positioning the die at the first station in a first direction.

[0007] Furthermore, the coarse positioning mechanism includes: A coarse positioning block having an inclined surface for guiding the template strip; A coarse positioning moving drive mechanism, connected to the coarse positioning block, is used to drive the coarse positioning block to move in a second direction perpendicular to the first direction until it forms a constraint space with the fixed stop edge of the first station to constrain the position of the mold strip in the first direction.

[0008] Furthermore, a limiting plate is provided at the position opposite to the opening of the constraint space in the first station to limit the position of the mold strip in the second direction.

[0009] Furthermore, the die strip feeding mechanism includes: Flexible claw; A feeding and moving drive mechanism is connected to the elastic pawl to drive the elastic pawl to move in a first direction; wherein the elastic pawl is configured such that... During the movement from the first station to the second station, the mold strip is pushed to move; during the movement from the second station to the first station, after contacting the mold strip, it retracts under the action of the mold strip to pass over the mold strip.

[0010] Furthermore, the module strip precision positioning and fixing mechanism includes: The pressure template has clearance holes for avoiding the terminal area of ​​the mold strip and is connected to at least two positioning posts, wherein the mold strip is provided with positioning holes that cooperate with the positioning posts; A pressure template moving drive mechanism is connected to the pressure template to drive the pressure template to move toward the corresponding mold strip to press the mold strip.

[0011] Furthermore, a guide mechanism for guiding the movement of the pressure template is provided between the pressure template and the support platform.

[0013] Furthermore, the mold strip terminal assembly device also includes two terminal feeding mechanisms, corresponding to the mold strips at the first station and the second station respectively, for feeding the first terminal onto the mold strip at the first station and the second terminal onto the mold strip at the second station respectively.

[0014] Furthermore, the terminal feeding mechanism includes a terminal suction nozzle and a three-axis robotic arm connected to the terminal suction nozzle.

[0015] By adopting the above technical solution, this utility model presses the first terminal and the second terminal at the first station and the second station respectively.

Detailed Implementation

[0017] To make the contents of this utility model easier to understand, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0018] like Figures 1 to 7 As shown, a module-mounted terminal assembly includes: The support platform 1, used to support the mold strip 2, has a first station 10 and a second station 20 arranged side by side in a first direction; The die strip feeding mechanism 3 is used to feed the die strip 2 from the first station 10 to the second station 20; Two mold strip precision positioning and fixing mechanisms 4 are respectively corresponding to the mold strips 2 of the first station 10 and the second station 20. They are used to precisely position the corresponding mold strips 2 and press the mold strips 2 during the pressing process. Two terminal pressing mechanisms 5 are respectively corresponding to the first terminal on the mold strip 2 after the first station 10 is precisely positioned and the second terminal on the mold strip 2 after the second station 20 is precisely positioned. They are used to press the corresponding terminal into the corresponding mold strip 2 during the pressing process.

[0019] It should be noted that the mold strip 2 can be an injection molding strip, equivalent to the mold core. The first terminal and the second terminal can be different terminals assembled at different positions on the mold strip 2. They can also be terminals with a sequential assembly order, for example, the first terminal is pressed into the mold strip 2 first, and then the second terminal is pressed into the first terminal, and so on.

[0020] Specifically, during the process of installing terminals onto the mold strip 2, the mold strip 2 is first placed into the first station 10 of the support platform 1. Then, the mold strip 2 is precisely positioned and fixed by the mold strip precision positioning and fixing mechanism 4 of the first station 10. Then, the terminal pressing mechanism 5 presses the terminal suspended on the mold strip 2 into the mold strip 2. After the mold strip precision positioning and fixing mechanism 4 releases the mold strip 2, the mold strip feeding mechanism 3 feeds the mold strip 2 to the second station 20. Then, the mold strip precision positioning and fixing mechanism 4 of the second station 20 precisely positions and fixes the mold strip 2 again. Then, the terminal pressing mechanism 5 of the second station 20 presses the suspended second terminal into the mold strip 2.

[0021] In this embodiment, the first terminal and the second terminal are pressed into place at the first station 10 and the second station 20 respectively. Pressing into two different types of terminals separately can improve the pressing accuracy of the first terminal and the second terminal, ensure product quality, and meet high precision requirements. Furthermore, pressing into place at the first station 10 and the second station 20 simultaneously can improve assembly efficiency. In addition, the mold strip precision positioning and fixing mechanism 4 precisely positions and fixes the mold strip 2, ensuring the positional accuracy of the mold strip 2 when pressing into the terminal, further improving the pressing quality. It can also reduce the positional requirements of the initially placed mold strip 2, further improving efficiency.

[0022] The solution in this embodiment can meet the requirements of assembling two types of extremely small terminals (diameter φ1.00±0.015; diameter φ2.08-0.022) inside the module strip, with a repeatability of ±0.005mm and a position accuracy as high as 0.0016mm.

[0023] In some examples, such as Figure 1and Figure 3 As shown, the die strip terminal assembly device also includes a coarse positioning mechanism 6, which is used to coarsely position the die strip 2 of the first station 10 in the first direction.

[0024] Specifically, the initial position of the mold strip 2 at the second station 20 is determined by the feeding stroke of the mold strip feeding mechanism 3, while the initial position at the first station 10 is determined by the external feeding mechanism or manual feeding. By setting a coarse positioning mechanism 6 at the first station 10, the positional accuracy requirements of the mold strip placed at the first station 10 can be further reduced.

[0025] In some examples, such as Figure 1 and Figure 3 As shown, the coarse positioning mechanism 6 includes: The coarse positioning block 61 has an inclined surface 611 for guiding the mold strip 2; The coarse positioning moving drive mechanism 62 is connected to the coarse positioning block 61 and is used to drive the coarse positioning block 61 to move in a second direction perpendicular to the first direction to form a constraint space with the fixed stop 8 of the first station 10 to constrain the position of the mold strip 2 in the first direction.

[0026] The coarse positioning moving drive mechanism 62 can be, but is not limited to, a cylinder, a hydraulic cylinder, an electric cylinder, an electric push rod, etc.

[0027] The coarse positioning moving drive mechanism 62 drives the coarse positioning block 61 to extend. The coarse positioning block 61 and the fixed baffle 8 together form a constraint space. The mold strip 2 enters the constraint space under the guidance of the inclined surface 611, thereby effectively coarsely positioning the position of the mold strip 2 in the first direction. This embodiment saves manual placement time by fixing the mold strip 2 through dual positioning. In addition, the coarse positioning moving drive mechanism 62 drives the coarse positioning block 61 to retract, so as not to interfere with the movement of the mold strip 2 to the second station 20.

[0028] In some examples, such as Figures 1 to 7 As shown, a limiting plate 9 is provided at the position opposite to the constraint space opening of the first station 10 to limit the position of the mold strip 2 of the first station 10 in the second direction.

[0029] In this way, the position of the template 2 in the second direction can be limited.

[0030] In some examples, such as Figure 1 and Figure 4 As shown, the die strip feeding mechanism 3 includes: 31 flexible claws; The feeding and moving drive mechanism 32 is connected to the elastic pawl 31 to drive the elastic pawl 31 to move in a first direction; wherein the elastic pawl 31 is configured such that... During the movement from the first station 10 to the second station 20, the mold strip 2 is pushed to move; during the movement from the second station 20 to the first station 10, after contacting the mold strip 2, it retracts under the action of the mold strip 2 to pass over the mold strip 2.

[0031] In this way, once the mold 2 in the first station 10 is removed from the first station 10, a new mold strip 2 can be placed into the first station 10. The new mold strip 2 will not interfere with the reset of the elastic claw 31, thus avoiding waiting time and further improving assembly efficiency.

[0032] The material feeding and moving drive mechanism 32 can be, but is not limited to, a cylinder, hydraulic cylinder, electric cylinder, electric push rod, etc. The elastic claw 31 has various structures; one is listed here. The elastic claw 31 contains a spring, which allows it to maintain its normal position above the bottom surface of the die strip 2 under the action of the spring. During the resetting process, the die strip 2 acts on its inclined surface, compressing the spring and causing it to pass under the die strip 2 to reset. After passing under the die strip 2, it springs back under the action of the spring, remaining above the bottom surface of the die strip 2.

[0033] In some examples, such as Figure 5 As shown, the module strip precision positioning and fixing mechanism 4 includes: The pressure template 41 has a clearance hole 411 for avoiding the terminal area of ​​the mold strip 2, and is connected to at least two positioning posts 412. The mold strip 2 is provided with positioning holes 21 that cooperate with the positioning posts 412. The pressing template moving drive mechanism 42 is connected to the pressing template 41 to drive the pressing template 41 to move toward the corresponding mold strip 2 to press the mold strip 2.

[0034] The lower end of the positioning column 412 can be tapered. The pressure template moving drive mechanism 42 can be, but is not limited to, a cylinder, hydraulic cylinder, electric cylinder, electric push rod, etc.

[0035] In some examples, such as Figures 1 to 7 As shown, a guide mechanism 43 for guiding the movement of the pressure template 41 is arranged between the pressure template 41 and the support platform 1.

[0036] This allows the pressing template 41 to move smoothly. The guiding mechanism 43 may include guide posts disposed on the pressing template 41, the guide posts passing through guide holes on the support platform 1 or the frame, and buffer springs may also be fitted on the guide posts.

[0037] In some examples, such as Figure 1 and Figure 2 As shown, the terminal pressure compensation mechanism 5 includes: Pressure compensation component 51; The pressure compensation component moving drive mechanism 52 is connected to the pressure compensation component 51 and is used to drive the pressure compensation component 51 to move in order to compensate the corresponding terminal.

[0038] The pressure-repairing assembly 51 may include a pressure plate and several pressure blocks fixed on the pressure plate. The pressure-repairing assembly presses onto the corresponding terminals through the clearance hole 411. The pressure-repairing assembly movement drive mechanism 52 may be a two-dimensional robotic arm.

[0039] In some examples, such as Figure 7 As shown, the mold strip terminal assembly device also includes two terminal feeding mechanisms 7, which correspond to the mold strips 2 of the first station 10 and the second station 20, respectively, and are used to feed the first terminal onto the mold strip 2 of the first station 10 and the second terminal onto the mold strip 2 of the second station 20.

[0040] like Figure 7 As shown, the terminal feeding mechanism 7 includes a terminal suction nozzle 71 and a three-axis robotic arm 72 connected to the terminal suction nozzle 71. The suction nozzle 71 picks up the corresponding terminal, and the three-axis robotic arm 72 drives the suction nozzle 71 to move.

[0041] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
