Description

Technical Field

[0001] The present invention relates to the field of mechanical equipment automation, and particularly to a quick-insert terminal device for a headphone socket connector assembly device. Background Art

[0002] With the increasing popularity of mobile phones, the quantity and quality requirements for mobile phone components are getting higher and higher. As one of the mobile phone components, for the existing fully manual assembly and inspection method or semi-automatic assembly and inspection method of the mobile phone socket, the production efficiency is low, the product qualification rate is not high, resulting in high product costs and low competitiveness, which can no longer meet the market demand. Therefore, it is necessary to design an automatic assembly device that can automatically, quickly, and accurately insert terminals into the headphone socket, improve efficiency, and reduce the occurrence of safety accidents. Summary of the Invention

[0003] To solve the existing technical problems, the present invention provides a quick-insert terminal device for a headphone socket connector assembly device.

[0004] For the convenience of description, words such as "left and right" and "up and down" are used in the present invention. These orientation words are only used to express the positional relationship between the various structures in the structure of the present invention, and do not represent a limitation on the structure.

[0005] The specific content of the present invention is as follows: A quick-insert terminal device for a headphone socket connector assembly device includes a feeding assembly and a raw material cutting and terminal inserting assembly. The feeding assembly is an intermittent feeding mechanism. The raw material cutting and terminal inserting assembly includes a planar cam roller mechanism, a timing control mechanism, and a workpiece clamping mechanism. The timing control mechanism controls the movement sequence of the planar cam roller mechanism and the workpiece clamping mechanism. The terminal is clamped by the workpiece clamping mechanism through the movement of the planar cam roller mechanism to perform the terminal inserting work.

[0006] Further, the feeding assembly includes a motor, a motor support, a feeding ratchet, a fixing plate, a first pressing plate, and a terminal tape. The motor is installed on the motor support. The terminal tape is arranged in the pressing groove of the fixing plate. The first pressing plate is arranged above the fixing plate. The motor drives the feeding ratchet to rotate. The pawl of the feeding ratchet fits with the positioning hole on the terminal tape. The motor drives the feeding ratchet to rotate. The pawl on the feeding ratchet fits with the positioning hole on the terminal tape. When the ratchet rotates, the terminal tape is transported from left to right through the guide groove between the fixing plate and the pressing plate. For each rotation of the angle of one pawl, one unit of the workpiece on the terminal tape is conveyed to the next process.

[0007] Further, the planar cam roller mechanism includes a cylinder, a planar cam push rod driven by the cylinder, and rollers located in the cam tracks of the planar cam push rod. The rollers include a first roller, a second roller, and a third roller. The planar cam push rod is provided with a first cam track, a second cam track, and a third cam track, each with an obtuse cross-section. The cross-section angle directions of the first cam track and the second cam track are the same, and the cross-section angle direction of the third cam track is opposite to that of the first cam track.

[0008] Further, the timing control mechanism includes a first push rod, a second push rod, a first stop block, a second stop block, a fixed seat, and a sliding support. The first push rod is located in the card slot formed by the first stop block and the fixed seat, and the second push rod is located in the card slot formed by the second stop block and the fixed seat. The fixed seat is fixed to the frame of the device, and the sliding support is connected to the planar cam push rod. In the initial state, the planar cam push rod moves to the left and the sliding support remains stationary. In the pressing state, the sliding support moves downward by a certain distance. After pressing, the sliding support continues to move to the left with the planar cam push rod. In the terminal inserting state, the sliding support moves to the extreme position. After the terminal is separated from the raw material cutting and terminal inserting assembly, the sliding support moves to the right with the planar cam push rod and returns to the initial position.

[0009] Further, the timing control mechanism further includes a return spring, which is arranged between the second stop block and the fixed seat. When the push rod moves, the stop block can be pressed against the frame by the return spring. When the push rod moves to the specified position, the return spring resets and the stop block pops out to prevent further movement.

[0010] Further, a first stroke limit block and a second stroke limit block are also provided on the frame of the device. It also includes a slider, which is fixedly connected to the slider support and is arranged between the first stroke limit block and the second stroke limit block. This can prevent the cylinder from operating beyond the stroke and ensure the accurate movement of the slider support.

[0011] Further, the workpiece clamping mechanism includes a third push rod, a pressing block, a pressing plate, a cutting block, a planar cam, a sliding rod, a fixed pin, a fourth roller, and a roller fixed seat. The planar cam is fixedly connected to the sliding rod, the pressing block is fixedly connected to the sliding rod, the sliding rod can move vertically within the sliding support, the fourth roller is arranged between the roller fixed seat and the sliding rod, the third push rod is fixedly connected to the cutting block, the pressing plate is fixed to the cutting block, the fixed pin is arranged on the pressing plate, and when pressing, the fixed pin passes through the circular positioning hole on the terminal tape and inserts into the pressing block.

[0012] The working process of the raw material cutting and terminal inserting sub - assembly of the present invention is as follows: Starting from the initial position, the air cylinder drives the flat cam push rod to move. The first roller, the second roller, and the third roller move in the flat cam push rod according to their respective cam tracks. When the flat cam push rod extends, since the first push rod is at the right end of the first stop block and is in the card slot formed by the first stop block and the fixed seat, and the fixed seat is fixedly connected to the support on the frame, when the flat cam push rod moves to the left, the sliding support does not move.

[0013] The second push rod is above the second stop block. There is a return spring between the second stop block and the fixed seat. Driven by the second roller, the second push rod presses the second stop block onto the fixed seat; the third push rod is fixedly connected to the cutting block, and the pressing plate is fixed on the cutting block. According to the movement law of the third roller in the cam track, the cutting block moves downward accordingly, and the workpiece tape is subjected to a shearing force and is cut off from the terminal tape. The fixing pin on the pressing plate passes through the circular positioning hole on the terminal tape and inserts into the pressing block. At this time, the cutting block, the pressing block, and the cut - out terminal workpiece move downward for a certain distance, and the spring between the sliding support and the pressing block ensures that the terminal workpiece is pressed tightly.

[0014] As the flat cam push rod continues to move to the left, the first push rod driven by the first roller leaves the card slot formed by the first stop block and the fixed seat, and the sliding support can move to the left together with the flat cam push rod.

[0015] The pressing block and the cutting block clamp the terminal workpiece as a whole and extend forward to insert into the main body of the earphone socket. Then, since the flat cam is fixedly connected to the sliding rod, the pressing block is fixedly connected to the sliding rod, and the sliding rod can move vertically within the sliding support. The frame is fixedly connected to the roller fixed seat, and the fourth roller has only one degree of freedom to rotate around the roller center. Therefore, as the sliding support moves, the fourth roller rolls on the flat cam, causing the pressing block to move downward, and the terminal thus separates from the pressing block. Then the sliding support moves to the limit position. At this time, the second push rod driven by the second roller moves to the left end of the second stop block, and the second stop block pops back under the action of the compressed spring between it and the fixed seat, and the push rod is in the card slot formed by the second stop block and the fixed seat.

[0016] After the terminal is inserted into the main body of the earphone socket and the pressing block is loosened downward, the flat cam push rod retracts. At this time, since the second push rod is at the left end of the second stop block and is in the card slot formed by the second stop block and the fixed seat, when the flat cam push rod moves to the right, the sliding support does not move; the first push rod is above the first stop block, and there is a spring - supported connection between the first stop block and the fixed seat. Driven by the first roller, the first push rod presses the first stop block downward; the third push rod driven by the third roller moves upward, and at the same time, the cutting block fixedly connected to the push rod also moves upward, and the fixing pin is pulled out from the terminal and the pressing block, and the terminal thus separates from the cutting block.

[0017] As the flat cam push rod continues to move to the right, the second push rod leaves the card slot formed by the second stop block and the fixed seat driven by the second roller, and the sliding support can move to the right together with the flat cam push rod; the sliding support and the upper cutting block also return to the initial position together with the flat cam push rod; in addition, the first push rod moves to the right end of the first stop block driven by the first roller, and the first stop block pops back under the action of the spring compressed between it and the fixed seat, and the first push rod is in the card slot formed by the first stop block and the fixed seat and returns to the initial position.

[0018] Advantages of the present invention: The present invention can automatically, quickly and accurately insert terminals into the earphone socket, improve efficiency, reduce the occurrence of safety accidents, liberate operators from dangerous, monotonous and heavy physical labor, effectively reduce labor costs, and improve production efficiency.

In the pressing state, the sliding support 36 moves downward by a certain distance. After pressing, the sliding support 36 continues to move to the left with the planar cam push rod 21. In the state of inserting the terminal, the sliding support 36 moves to the extreme position. After the terminal is separated from the raw material cutting and terminal inserting assembly, the sliding support 36 moves back to the initial position to the right with the planar cam push rod 21.

[0030] Preferably, in this embodiment, the timing control mechanism further includes a return spring 37, and the return spring 37 is arranged between the second stop block 34 and the fixing seat 35.

It further includes a slider 39, which is fixedly connected to the slider support 36 and is arranged between the first stroke limit block 381 and the second stroke limit block 382. This can prevent the cylinder 20 from operating beyond the stroke and ensure the accurate movement of the slider support.

[0032] Preferably, in this embodiment, the workpiece clamping mechanism includes a third push rod 40, a pressing block 41, a second pressing plate 42, a cutting block 43, a planar cam 44, a sliding rod 45, a fixing pin 46, a fourth roller 47, and a roller fixing seat 48; the planar cam 44 is fixedly connected to the sliding rod 45, the pressing block 41 is fixedly connected to the sliding rod 45, the sliding rod 45 can move vertically within the sliding support 36, the fourth roller 47 is arranged between the roller fixing seat 48 and the sliding rod 45, the third push rod 40 is fixedly connected to the cutting block 43, the second pressing plate 42 is fixed on the cutting block 43, the fixing pin 46 is arranged on the second pressing plate 42, and when pressing, the fixing pin 46 passes through the circular positioning hole on the terminal tape 15 and inserts into the pressing block 41.

[0033] The working process of the raw material cutting and terminal inserting assembly of the present invention is as follows: Starting from the initial position, the cylinder 20 drives the planar cam push rod 21 to move, and the first roller 221, the second roller 222, and the third roller 223 respectively move in the planar cam push rod 21 according to the corresponding cam tracks. When the planar cam push rod 21 extends, since the first push rod 31 is at the right end of the first stop block 33 and is in the card slot formed by the first stop block 33 and the fixed seat 35, and the fixed seat 35 is fixedly connected to the support on the frame, when the planar cam push rod 21 moves to the left, the sliding support 36 does not move.

[0034] The second push rod 32 is above the second stop block 34, and there is a return spring 37 between the second stop block 34 and the fixed seat 35. The second push rod 32 presses the second stop block 34 against the fixed seat 35 under the drive of the second roller 222; the third push rod 40 is fixedly connected to the cutting block 43, and the second pressing plate 42 is fixed on the cutting block 43. According to the movement law of the third roller 223 in the cam track, the cutting block 43 moves downward accordingly, and the workpiece tape is subjected to a shearing force and is cut off from the terminal tape 15. The fixing pin 46 on the second pressing plate 42 passes through the circular positioning hole on the terminal tape 15 and inserts into the pressing block 41. At this time, the cutting block 43, the pressing block 41, and the cut-off terminal workpiece move downward a certain distance, and the spring between the sliding support 36 and the pressing block 41 ensures that the terminal workpiece is pressed.

[0035] As the planar cam push rod 21 continues to move to the left, the first push rod 31 leaves the card slot formed by the first stop block 33 and the fixed seat 35 under the drive of the first roller 221, and the sliding support 36 can move to the left together with the planar cam push rod 21.

[0036] The pressing block 41 and the cutting block 43 clamp the terminal workpiece together and project forward as a whole, and are inserted into the main body of the earphone socket. After that, since the planar cam 44 is fixedly connected to the sliding rod 45, the pressing block 41 is fixedly connected to the sliding rod 45, and the sliding rod 45 can move in the vertical direction within the sliding support 36. The frame is fixedly connected to the roller fixed seat 48, and the fourth roller 47 has only one degree of freedom to rotate around the roller center. Therefore, as the sliding support 36 moves, the fourth roller 47 rolls on the planar cam 44, causing the pressing block 41 to move downward, and the terminal thus separates from the pressing block 41. Then the sliding support 36 moves to the limit position.

[0037] After the terminal is inserted into the main body of the earphone socket and the pressing block 41 is loosened downward, the planar cam push rod 21 retracts. At this time, since the second push rod 32 is at the left end of the second stop block 34 and is in the card slot formed by the second stop block 34 and the fixed seat 35, when the planar cam push rod 21 moves to the right, the sliding support 36 does not move; the first push rod 31 is above the first stop block 33, and there is a spring support connection between the first stop block 33 and the fixed seat 35. The first push rod 31 presses the first stop block 33 downward driven by the first roller 221; the third push rod 40 moves upward driven by the third roller 223, and at the same time the cutting block 43 fixed together with the push rod also moves upward, and the fixing pin 46 is pulled out from the terminal and the pressing block 41, and the terminal thus separates from the cutting block 43.

[0038] As the planar cam push rod 21 continues to move to the right, the second push rod 32 leaves the card slot formed by the second stop block 34 and the fixed seat 35 driven by the second roller 222, and the sliding support 36 can move to the right together with the planar cam push rod 21; the sliding support 36 and the upper cutting block 43 also return to the initial position together with the planar cam push rod 21; in addition, the first push rod 31 moves to the right end of the first stop block 33 driven by the first roller 221, and the first stop block 33 pops back under the action of the spring compressed between it and the fixed seat 35, and the first push rod 31 is in the card slot formed by the first stop block 33 and the fixed seat 35 and returns to the initial position.
