When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0027] The workpiece processed by the assembly device of the present invention is shown in Figure 1 As shown, it includes a first terminal 101 , a second terminal 102 , a third terminal 103 and an outer tube 100 sleeved outside the first terminal 101 , the second terminal 102 , and the third terminal 103 .

[0028] See also Figures 2 to 6 An embodiment of the assembly device of the present invention shown in the figure comprises: a clamping mechanism 1 and an assembly mechanism 2. The clamping mechanism 1 comprises a movable clamping portion 11, the clamping portion 11 comprises an outer clamping portion 111 and an inner clamping portion 112 arranged in a nested manner, the outer clamping portion 111 is provided with a first terminal accommodating cavity 1111 and a second terminal accommodating cavity 1112 for accommodating a first terminal and a second terminal respectively, the outer clamping portion 111 clamps and releases the terminal through a first driving component 113, the inner clamping portion 112 is provided between the first terminal accommodating cavity 1111 and the second terminal accommodating cavity 1112, and an outer tube accommodating cavity 1121 is provided inside the inner clamping portion 112, and the inner clamping portion 112 clamps and releases the outer tube through a second driving component 114.

[0029] The assembly mechanism 2 is used to push the terminal assembly on the clamping part 11 into the outer tube on the clamping part 11. The assembly mechanism 2 includes two ejector pins 23 and a third driving component 22 that drives the two ejector pins 23 to perform linear reciprocating motion in opposite directions. The two ejector pins 23 are respectively arranged on both sides of the clamping part 11.

[0030] The clamping mechanism 1 further comprises a fourth driving assembly 12, which is drivingly connected to the clamping portion 11 to drive the clamping portion 11 to move between a first position and a second position. When the clamping portion 11 is located at the first position, the clamping portion 11 receives the feed, and the first terminal, the second terminal and the outer tube respectively enter the first terminal accommodating cavity 1111, the second terminal accommodating cavity 1112 and the outer tube accommodating cavity 1121. When the clamping portion 11 is located at the second position, the assembly mechanism 2 assembles the terminal into the outer tube held by the clamping portion 11.

[0031] By providing a clamping mechanism 1 that can clamp multiple terminals and outer tubes and an assembling mechanism 2 that is matched with the clamping mechanism 1, the work of assembling multiple terminals into the outer tube can be automatically completed, the work efficiency is high, the space setting is reasonable, the floor space is small, and the cost is low.

[0032] In this embodiment, a third terminal accommodating cavity 1113 for accommodating a third terminal is further provided in the outer clamping portion 111 between the first terminal accommodating cavity 1111 and the second terminal accommodating cavity 1112, and the outer clamping portion 111 clamps and releases the third terminal through the second driving assembly 114. In this way, the state of clamping three terminals at the same time is achieved, which greatly improves the production efficiency.

[0033] As a further optimization of this embodiment, the assembly mechanism 2 is arranged on a conveying mechanism 3. Specifically, the conveying mechanism 3 includes a turntable 31 that can rotate around its own axis. The turntable 31 includes two relatively arranged and synchronously moving ones. The turntable 31 is provided with a plurality of stations for accommodating assembled workpieces. When one of the stations moves to the clamping portion 11 located at the second position, the station is set as a receiving station for receiving assembled workpieces. The assembly mechanism 2 is arranged next to the receiving station. Compared with the linear conveying mechanism 3, the setting of the turntable 31 can greatly reduce the floor space of the overall device and reduce the production and processing costs. At the same time, by setting the receiving station, the stations on the turntable 31 are orderly classified, which can improve the management efficiency.

[0034] Each of the workstations comprises a first base and a second base which are respectively arranged on the two turntables 31 and are arranged correspondingly. The first base is provided with a first rotating shaft 21 which can be extended toward the second base, and the second base is provided with a second rotating shaft 211 which can be extended toward the first base. When the workstation moves to the receiving station, the second rotating shaft 211 and the first rotating shaft 21 are respectively ejected by the ejector pin 23 and the first terminal, the second terminal and the third terminal are inserted into the outer tube. The first rotating shaft 21 and the second rotating shaft 211 of the workstation are respectively driven and connected with a fifth driving component, and the fifth driving component drives the first rotating shaft 21 and / or the second rotating shaft 211 to rotate. In this embodiment, the fifth driving component includes a rotatable rubber wheel, and correspondingly, a transmission rubber wheel is provided on the second rotating shaft 211 and / or the first rotating shaft 21. The rubber wheel drives the first rotating shaft 21 and / or the second rotating shaft 211 to rotate through the transmission rubber wheel on the second rotating shaft 211 and / or the first rotating shaft 21, thereby assisting the first rotating shaft 21 and the second rotating shaft 211 to penetrate into the outer tube.

[0035] The first rotating shaft 21 and the second rotating shaft 211 used to eject the outer tube and the terminal are set separately from the ejector pin 23, so that the rotation state of the workpiece after assembly can be formed while ensuring the assembly effect, avoiding the need to set up a separate rotation drive component, and the work efficiency is high. Preferably, in order to ensure the working accuracy during assembly, the assembly mechanism 2 also includes a sixth driving component 24 used to drive the first rotating shaft 21 and the second rotating shaft 211 to penetrate the first terminal and the second terminal respectively. The sixth driving component 24 drives the third driving component 22 and the ejector pin 23 to move, thereby ejecting the first rotating shaft 21 to penetrate the terminal. At this time, the outer clamping part 111 releases the terminal, and then the third driving component 22 drives the ejector pin 23 to eject the first rotating shaft 21 and the second rotating shaft 211 respectively, and the terminal is pushed into the outer tube.

[0036] As a further optimization of this embodiment, the station before the receiving station is set as a disengagement station, and reset mechanisms 4 are provided on both sides of the disengagement station for respectively resetting the first rotating shaft 21 and the second rotating shaft 211. Specifically, the reset mechanism 4 includes mechanical claws 41 for respectively grabbing the first rotating shaft 21 and the second rotating shaft 211, and the mechanical claws 41 are driven and connected to the cylinder. When the workpiece is transported to the reset mechanism 4 on the turntable 31, the mechanical claws 41 are driven by the cylinder to grab and reset the first rotating shaft 21 and the second rotating shaft 211, respectively, so that the first rotating shaft 21 and the second rotating shaft 211 lose power and stop rotating.

[0037] A receiving mechanism 5 is provided above the ejection station for grabbing the formed workpiece and moving it to an external collector, including a grabbing assembly 51 and a cylinder group 52 for driving the grabbing assembly to move. When the receiving mechanism 5 grabs the formed workpiece, the reset mechanism 4 drives the first rotating shaft 21 and the second rotating shaft 211 to reset.

[0038] Specifically, the first driving assembly 113 includes a rotating arm 13 and a power assembly 12 for driving the rotating arm 13 to rotate, and the clamping part 11 is detachably connected to the rotating arm 13. In this way, modular assembly of the clamping part 11 is achieved, and production personnel can select different clamping parts 11 according to the heat shrink tube to be processed, thereby achieving rapid replacement of processing categories and improving the processing application scenarios of the equipment.

[0039] In this embodiment, the power assembly 12 is driven to connect the middle part of the rotating arm 13, and the number of the clamping parts 11 is two, which are respectively arranged at the two ends of the rotating arm 13. In this way, the clamping part 11 can be quickly switched between the first position and the second position. The number of the clamping parts 11 can be increased or decreased as needed, and the number of the rotating arms 13 can be increased or decreased accordingly.

[0040] Specifically, the first driving assembly 113 and the second driving assembly 114 are sequentially arranged at the end of the rotating arm 13 in a horizontal direction and perpendicular to the direction of the rotating arm 13, and the driving directions of the second driving assembly 114 and the first driving assembly 113 are arranged along the direction of the rotating arm 13. By arranging the second driving assembly 114 and the first driving assembly 113 to be perpendicular to the direction of the rotating arm 13, it is prevented that the external supporting mechanism interferes with the movement of the rotating arm 13 during the conversion of the clamping state.

[0041] As a further optimization of this embodiment, the second driving assembly 114 and the first driving assembly 113 are both left-right moving cylinders, and correspondingly the outer clamping portion 111 and the inner clamping portion 112 are both configured to be openable or closed along the direction of the left-right moving cylinders.

[0042] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
