[0020] Compared with the prior art, the present invention has the following beneficial effects:

Dipping with solder resist is an auxiliary tinning process. The product dipped with solder resist can make the tinning fuller and the tinning faster, and the rotary tinning of the wire is achieved through the cam connecting rod mechanism, which changes the sputtering of the tinning auxiliary material during tinning of the existing equipment and avoids the contamination of the tinning auxiliary material near the tinning mechanism;

Then, the rotating fixture mechanism rotates the wire with the riveted terminal to the shell insertion mechanism station. The shell insertion mechanism inserts the riveted terminal on the wire into the plastic shell, thereby completing the shell insertion work. The rotating fixture mechanism rotates the wire after the shell is inserted into the shell insertion detection mechanism. The shell insertion detection mechanism detects the plastic shell inserted on the wire to ensure that the plastic shell and the terminal are accurately in place Finally, the rotating fixture table mechanism rotates the inspected wire to the wire-taking mechanism, and the wire-taking mechanism discharges the processed finished product, thereby completing the automated processing of the wire. This layout design allows the wire to be clamped by the rotating fixture table mechanism and pass through each workstation in turn through clockwise rotation, achieving continuity and compactness of the processing procedure, reducing the transmission distance and time of the wire between different mechanisms, and the entire processing process from wire calibration to finished product discharge does not require manual intervention. Each mechanism works together under the drive of the cam-link mechanism to realize full-process automated production, greatly reducing manual labor intensity and reducing labor costs.

DETAILED DESCRIPTION

[0039] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0040] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0041] like Figures 1 to 14 As shown, a new cam tinning and shell insertion machine provided as an embodiment of the present invention includes a machine base 1, a line adjustment mechanism 2, a rotary tinning mechanism 3, a front end tool holder mechanism 4, a terminal crimping mechanism 6, a rear stripping mechanism 5, a wire pulling mechanism 7, a shell insertion mechanism 8, a rotating fixture platform mechanism 9, a shell insertion detection mechanism 10, a wire taking mechanism 11, a control mechanism 12 and a cam connecting rod mechanism, wherein the control mechanism 12 is connected to the cam connecting rod mechanism, and the cam connecting rod mechanism is respectively connected to the line adjustment mechanism 2, the rotary tinning mechanism 3, the front end tool holder mechanism 4, the terminal crimping mechanism 6, the rear stripping mechanism 5, the wire pulling mechanism 7, the shell insertion mechanism 8, the shell insertion detection mechanism 10 and the wire taking mechanism 11 and provides a power source for them;

[0042] The line calibration mechanism 2, the rotary tinning mechanism 3, the front end tool holder mechanism 4, the crimping terminal mechanism 6, the rear stripping mechanism 5, the wire pulling mechanism 7, the shell plugging mechanism 8, the rotary fixture table mechanism 9, the shell plugging detection mechanism 10 and the wire taking mechanism 11 are all installed on the machine base 1, the rotary fixture table mechanism 9 is installed in the middle of the machine base 1, the wire pulling mechanism 7 is installed on the machine base 1 and is located above the rotary fixture table mechanism 9, and the rotary tinning mechanism 3, the front end tool holder mechanism 4, the crimping terminal mechanism 6, the rear stripping mechanism 5, the shell plugging mechanism 8, the shell plugging detection mechanism 10 and the wire taking mechanism 11 are respectively provided around the rotary fixture table mechanism 9, and the line calibration mechanism 2 is provided on one side of the machine base 1 and cooperates with the rotary tinning mechanism 3 and the wire pulling mechanism 7 respectively;

[0043] The wire enters the rotating tinning mechanism 3 through the wire alignment mechanism 2. The wire pulling mechanism 7 pulls the wire and pulls out the wire of the set length. The rotating fixture mechanism 9 clamps the pulled wire and rotates it to the front end tool holder mechanism 4. The front end tool holder mechanism 4 cuts the wire. This process is the wire winding work.

[0044] While the wire is being pulled, the front-end tool holder mechanism 4 strips the wire, and the rotating fixture mechanism 9 conveys the stripped wire to the rotating tinning mechanism 3. The rotating tinning mechanism 3 dips the stripped wire into solder resist and completes the tinning process. Dipping with solder resist is an auxiliary process for tinning. The product dipped with solder resist can make the tinning more full and the tinning faster.

[0045] After the wire is put on the line, the rotating fixture table mechanism 9 rotates one station clockwise and moves the wire to the lowering mechanism for processing. If the next station is not equipped with a processing mechanism, this station only serves as a stop.

[0046] The wire rotates clockwise on the rotating fixture table mechanism 9. When it rotates to the position of the rear stripping mechanism 5, the rear stripping mechanism 5 strips the rear end of the wire. The rotating fixture table mechanism 9 rotates the wire with the rear end stripped to the position of the crimping terminal mechanism 6. The crimping terminal mechanism 6 rivets the terminal to the rear end of the wire. Then, the rotating fixture table mechanism 9 rotates the wire with the riveted terminal to the position of the plug-in shell mechanism 8. The plug-in shell mechanism 8 inserts the riveted terminal on the wire into the plastic shell, thereby completing the plug-in shell work. The rotating fixture table mechanism 9 rotates the wire after the shell is inserted into the plug-in shell detection mechanism 10. The plug-in shell detection mechanism 10 detects the plastic shell inserted on the wire to ensure that the plastic shell and the terminal are in good condition. Precisely in place, finally, the rotating fixture table mechanism 9 rotates the tested wire to the wire taking mechanism 11, and the wire taking mechanism 11 discharges the processed finished product, thereby completing the automated processing of the wire. Such a layout design allows the wire to be clamped by the rotating fixture table mechanism 9 and pass through each workstation in turn through clockwise rotation, thereby achieving continuity and compactness of the processing procedure, reducing the transmission distance and time of the wire between different mechanisms, and the entire processing process from wire calibration to finished product discharge does not require human intervention. Each mechanism works together under the drive of the cam connecting rod mechanism to realize full-process automated production, greatly reducing manual labor intensity and reducing labor costs.

[0047] The rotary tinning mechanism 3 includes a tinning hexagonal column 31, a tinning rotating rod 32, a tinning connecting rod 33, a tinning slider 34, a rotating platform 35, a tinning lever 36, a torsion spring 37, an interference block 38 and a pressing assembly 39. One end of the tinning hexagonal column 31 is connected to the cam connecting rod mechanism, and the other end of the tinning hexagonal column 31 is connected to the tinning rotating rod 32 rotatably mounted on the machine base 1. One end of the tinning rotating rod 32 is connected to the tinning slider 34 horizontally slidably mounted on the machine base 1 through the tinning connecting rod 33.

The interference block 38 is connected to the rotating platform 35 through the torsion spring 37, and the interference block 38 cooperates with the pressing assembly 39 provided on one side of the rotating platform 35.

[0048] The cam-link mechanism drives the tinning rotating rod 32 to rotate through the tinning hexagonal column 31, and the tinning rotating rod 32 drives the tinning slider 34 to move back and forth through the tinning connecting rod 33. When the tinning slider 34 moves to the solder resist position, the cam-link mechanism drives the pressing assembly 39 to move downward, and the pressing assembly 39 drives the resistance block 38 to rotate 90 degrees by moving downward. The resistance block 38 drives the rotating shaft to rotate 90 degrees, and the rotating shaft drives the tinning lever 36 to rotate 90 degrees, so that the tinning lever 36 can drive the wire end on the wire to be immersed in the flux liquid surface, thereby completing the solder resist process of the wire. When the wire completes the solder resist process, the cam-link mechanism drives the pressing assembly 39 to move downward. The wire is moved up a certain distance so that the wire is separated from the solder resist liquid surface, and the cam connecting rod mechanism drives the tinning slider 34 to move to the tinning station, and the pressing component 39 moves down again and drives the wire into the tin surface, thereby completing the tinning of the wire; similarly, the pressing component 39 moves back to the initial state, and the cam connecting rod mechanism moves the wire after tinning to the wire pulling station, which makes it convenient for the wire pulling mechanism 7 to pull it, and also makes it convenient for the front-end tool holder mechanism 4 to cut the wire of the set length and peel off the rubber wrapped around the outside of the wire, and the rotating tinning mechanism 3 can drive the cut wire back to the initial state to repeat the solder resist and tinning processes.

The slide post 1 41 drives the lower knife holder 44 to move up and down at the same time, and the slide post 2 43 drives the upper knife holder 45 and the lower knife holder 44 to move in the opposite direction, so that the upper knife holder 45 and the lower knife holder 44 move away from or close to each other, thereby completing the cutting and front-end stripping of the wire, meeting the processing requirements of the wire, facilitating the subsequent processing of the wire, and improving the working efficiency and work quality of the shell plugging machine.

[0056] In a preferred embodiment, the position of the limit block 77 can be controlled by a motor and a screw rod. The motor drives the screw rod to rotate, and the screw rod can drive the limit block 77 to move by rotating and being threadedly connected to the limit block 77, thereby changing the contact position between the limit block 77 and the wire pulling slider 75, and then changing the pulling length of the wire by the wire pulling clamp 76, so that the wire pulling mechanism 7 can pull wires of different lengths at the same time, meet the diversified processing of wires, and improve the applicability and convenience of the shell plug-in machine.

At this time, since the terminal positioning mechanism 86 needs to occupy a certain length of the terminal when fixing the terminal, the plastic shell clamp 84 cannot fully insert the terminal into the plastic shell when it is first sent into the terminal. After the terminal positioning mechanism 86 is opened, the plastic shell needs to be inserted a second time to make the terminal fully inserted into the plastic shell; after the shell is inserted, the plastic shell clamp 84 opens and releases the plastic shell, and then the shell plug slider 81 brings the opened plastic shell clamp away from the terminal positioning mechanism 86, and at the same time the shell plug wire clamp 85 opens and releases the wire with the plastic shell inserted; wait for the next group of wires with riveted terminals, and repeat the above actions to complete the automatic shell insertion of the wire terminals, which is convenient for subsequent mechanisms to process them and improve the working efficiency and work quality of the shell plugging machine.

The cam connecting rod mechanism can drive the pulling rod 105 to rotate on the pulling block 104 by pulling the hexagonal column 103. The laminated shell clamp 102 clamps the plastic shell inserted on the terminal. Since the wire pressing carrier 93 presses one end of the wire, there will be a section of straight wire between the wire pressing carrier 93 and the laminated shell clamp 102. Then the pulling rod 105 rotates downward under the action of the spring 106, so that the pulling rod 105 contacts the straight section of wire between the wire pressing carrier 93 and the laminated shell clamp. The pulling rod 105 applies tension to the middle wire under the action of the spring 106. If the terminal inserted into the plastic shell is not inserted into place, the pulling rod 105 will contact the sensor 107 under the action of the spring 106, thereby screening out defective products.

The wire-taking slider can drive the wire-taking clamp 116 to move back and forth, so that the wire-taking clamp 116 can pull the wire on the wire pressing carrier 93, thereby completing the pulling of the wire. Then, the wire-taking slider 112 moves downward, thereby resetting the wire-taking slider 2 114 and the wire-taking clamp 116, waiting for the next group of wires.
