The core of the invention is to provide an automatic jacketing machine, which can automatically complete the process of sleeving heat-shrinkable sleeves, thereby greatly improving the production efficiency and the product qualification rate.

It should be noted that, the electronic device mentioned in the present invention refers to a capacitor or an inductor. Of course, other electronic devices are also possible, and the application is mainly described with respect to the case that the heat pipe needs to be sleeved on the capacitor.

The automatic jacketing machine provided by the invention comprises: a short rod 43, a sleeve assembly, a clamp, a knife 47 and a control device.

Wherein the short rod 43 is used for being supported inside the heat-shrinkable sleeve 6 and capable of moving along the heat-shrinkable sleeve 6, and the sleeve assembly is arranged between the arrangement position of the heat-shrinkable sleeve 6 and the position to be sleeved of the electronic device in a moving way;

the clamping piece is used for controlling the heat-shrinkable sleeve 6 to move towards the sleeve assembly and sleeved on the sleeve assembly so that the sleeve assembly pushes the short rod 43 to move; the cutter 47 is used for cutting off the part of the heat-shrinkable sleeve 6 sleeved on the sleeve assembly; the sleeve assembly has a pushing structure for pushing the heat-shrinkable sleeve 6 sleeved on the sleeve assembly and the pushing structure sleeved on the electronic device, and the sleeve assembly, the clamping piece and the cutter 47 are all connected with the control device.

It should be noted that the above operations are controlled by the control device, and the flat heat-shrinkable sleeve 6 may be held in the stretched state by the short rod 43, and the following steps may be achieved by the control device: the sleeve component moves to the position of the heat-shrinkable sleeve 6, the clamping piece controls the heat-shrinkable sleeve 6 to move and sleeve on the sleeve component, the sleeve component correspondingly pushes the short rod 43 to move downwards, the cutter 47 can cut off the heat-shrinkable sleeve 6 sleeved on the sleeve rod group from the rest part, the heat-shrinkable sleeve 6 sleeved on the sleeve component is obtained, the sleeve component moves to the position of the electronic device and aligns with the electronic device, and the pushing structure pushes the heat-shrinkable sleeve 6 sleeved on the sleeve component to the position that the heat-shrinkable sleeve 6 can be sleeved on the electronic device.

Since it is necessary to maintain the state of the heat-shrinkable tube 6 being stretched when the heat-shrinkable tube 6 is sheathed, a short rod 43 for maintaining the stretched state of the heat-shrinkable tube 6 is provided on the automatic jacketing machine. Meanwhile, the position of the short rod 43 within the heat shrink 6 may be moved along the heat shrink 6 to socket the heat shrink 6 on the sleeve assembly, specifically, the socket 511 mentioned in the following embodiments.

Preferably, in order to facilitate the spreading of the flat heat-shrinkable sleeve 6, the short rod 43 may be designed to be cylindrical and have a wedge-shaped end, so that the wedge-shaped end is conveniently inserted into the flat heat-shrinkable sleeve 6 and the heat-shrinkable sleeve 6 is spread by the cylindrical shaft.

The clamping member is used to clamp the heat shrink 6 and push the heat shrink 6 toward the sleeve assembly. The clamping piece is connected with the control device, so that the clamped heat-shrinkable sleeve 6 can be driven to be close to the sleeve assembly through the movement of the clamping piece, and finally, the heat-shrinkable sleeve is sleeved on the sleeve assembly.

The heat-shrinkable sleeve 6 is placed in a flat state and rolled into a disc shape in an unoperated state, and before the automatic jacketing machine is operated, it is necessary to insert the short rod 43 into the head end of the disc of heat-shrinkable sleeve 6 and clamp the heat-shrinkable sleeve 6 with the clamping member.

The process of inserting the short rod 43 into the head end of the heat shrink tube 6 and clamping by the clamping member can be performed manually, and the corresponding mechanical structure can be designed to complete the operation process, such as a mechanical arm structure. The sheathing of the heat-shrinkable sleeve 6 is then achieved by the following procedure.

Based on the above embodiment, the sleeve assembly includes: a loop bar 511, an ejector bar 512 and a hold-down piece;

the ejector rod 512 is sleeved in the sleeve rod 511, an elastic piece is arranged at the upper part of the ejector rod 512, one end of the elastic piece is fixed at the upper part of the ejector rod 512, and the other end of the elastic piece is used for being abutted or fixedly connected with the upper end of the sleeve rod 511; the hold-down piece is movable along the sleeve 511 to sleeve the heat shrink 6, which is sleeved on the sleeve 511, over the electronic device;

specifically, the clamping member, the cutter 47, the pressing member and the pressing member for driving the jack 512 to move are all in signal connection with the control device, so that the control of the clamping member, the cutter 47, the pressing member and the pressing member is realized through the control device.

During the working process of the automatic sleeve, the heat-shrinkable sleeve 6 moves towards the sleeve 511 under the control of the control device, and the short rod 43 can be pushed to move downwards after the heat-shrinkable sleeve 6 is sleeved on the sleeve 511 because the position of the short rod 43 can move along the heat-shrinkable sleeve 6.

On an automatic jacketing machine, the heat-shrinkable sleeve 6 and the working position of the electronic device needing to be sleeved with the heat-shrinkable sleeve 6 need to be arranged separately, so that the sleeve assembly can move between the heat-shrinkable sleeve position and the position of the electronic device to be sleeved, and the sleeve assembly is conveniently aligned with the heat-shrinkable sleeve 6 and the electronic device to be sleeved respectively. The movement may be horizontal movement, vertical movement, rotation, or the like.

It should be noted that, the ejector pin 512 is sleeved in the sleeve rod 511, an elastic member is disposed at the upper portion of the ejector pin 512, one end of the elastic member is fixed at the upper portion of the ejector pin 512, and the other end is abutted or fixedly connected with the upper end of the sleeve rod 511. When the ejector rod 512 is driven by the pressure member to perform axial movement, the elastic member generates elastic deformation, so after the pressure member withdraws the pressure applied to the ejector rod 512, one end of the elastic member is abutted or fixed with the upper end of the sleeve rod 511, and one end contacted with the sleeve rod 511 cannot recover the deformation, so that the restoring force of the elastic member drives the ejector rod 512 to move along the opposite direction of the pressed movement direction.

Preferably, the elastic member may be a spring 513 sleeved on the upper portion of the push rod 512.

The hold down is movable along the stem 511 to push out and push the heat shrink 6 over the stem 511 onto the electronic device.

The hold-down member may be a hold-down push rod in point contact with the loop 511; or a ring-shaped piece, which is in surface contact with the loop bar 511; of course, other structures are possible as long as the heat shrinkable tube 6 fitted over the sleeve 511 can be pushed out.

The hold down may be in direct contact with the stem 511 or may be positioned on the electronic device where the sleeve is to be placed, with the hold down in contact with the stem 511 when the stem 511 is aligned with the electronic device.

The clamping element, the tool 47, the hold-down element and the pressure element for driving the movement of the ram 512 are all connected to a control device, so that the operation of the components is continuous during the sleeving process.

In the sleeving process, the following steps can be realized through the control device:

the first step, the sleeve assembly is moved to the position of the heat-shrinkable sleeve and aligned with the heat-shrinkable sleeve 6, after the alignment, the pressure piece drives the ejector rod 512 to axially move so that the ejector rod 512 contacts the short rod 43 and pushes the short rod to the other end of the heat-shrinkable sleeve 6; at the same time, the clamping member clamps the heat-shrinkable sleeve 6 and pushes it in a direction opposite to the moving direction of the short rod 43, so that the heat-shrinkable sleeve 6 is sleeved on the sleeve 511 to form an inner and outer sleeved structure.

In the second step, the pressure piece withdraws the axial pressure to the ejector rod 512, and the end face of the ejector rod 512 is far away from the inner and outer sleeving structure due to the restoring force of the elastic piece, so that the heat shrinkage sleeve 6 can be cut by the cutter 47, the inner and outer sleeving structure is obtained, and the structure of the ejector rod 512 is not affected.

And thirdly, the sleeve assembly moves to the position of the electronic device to be sleeved, after the sleeve assembly is aligned with the electronic device, the pressing piece is controlled to move axially along the sleeve 511, and the heat-shrinkable sleeve 6 sleeved on the sleeve 511 is pushed out from the sleeve 511 and sleeved on the electronic device.

In this embodiment, the automatic sleeve machine can automatically complete the process of sleeving the heat-shrinkable sleeve 6 for the electronic device, and compared with the manual operation mode in the prior art, the production efficiency is greatly improved. Meanwhile, the control device controls the alignment of the sleeve component and the electronic device to be sleeved, so that the mechanical precision is higher, and the product qualification rate is obviously improved compared with the prior art. In addition, because the mechanical automatic sleeve is adopted, manual operation is avoided, and potential safety hazard problems possibly occurring in manual operation are avoided.

In order to realize that the hold-down piece can move axially along the stem 511, the structure further includes, based on the above embodiment: the second guide rod 501 is in signal connection with the control device and can be lifted, the top of the second guide rod 501 is fixedly connected with the upper horizontal plate 505, and a second pressing block 508 is arranged at one end of the upper horizontal plate 505; a bump 509 is fixed on the second pressing block 508, the movement of the bump 509 controls the movement of the lower pressing piece, and the bump 509 is in bidirectional contact with or fixedly connected with the lower pressing piece; the second guide rod 501 is further sleeved with a lower horizontal plate 503, and the sleeve rod 511 is connected to the lower horizontal plate 503.

It should be noted that, the second guide rod 501 is mounted on the second mounting frame 5, and by being connected with the control device, the control device can directly control the second guide rod 501 to perform lifting movement so as to implement lifting movement of the second guide rod 501.

The upper horizontal plate 505 is fixedly connected with the top of the second guide rod 501, so that the upper horizontal plate 505 can be lifted and lowered together with the second guide rod 501.

The second pressing block 508 is mounted on the upper horizontal plate 505, and the second pressing block 508 is further provided with a protrusion 509 for controlling the pressing down piece, so that the control device can control the lifting movement of the protrusion 509 by controlling the lifting of the second guide rod 501, thereby controlling the axial movement of the pressing down piece along the sleeve rod 511.

There is a bi-directional contact or fixed connection between the projection 509 and the follower to provide control of the axial movement of the follower along the stem 511. The protrusion 509 may be connected to the lower press, and the movement of the protrusion 509 drives the lower press to move along the axial direction of the stem 511. The contact between the bump 509 and the presser may be merely contact, but it should be noted that, in order for the bump 509 to enable movement of the presser in both directions toward and away from the electronic device to be sleeved, at least two contact points need to exist between the bump 509 and the presser, one contact point being capable of controlling the presser to be close to the electronic device to be sleeved and the other contact point being capable of controlling the presser to be away from the electronic device to be sleeved.

The second pressing block 508 and the protruding block 509 can be fixedly connected, such as welded, or detachably connected, such as bolted; of course, the projections 509 can also be embodied as an integral structure on the second pressure piece 508.

The shape of the bump 509 may be a cube, a cylinder, or other shapes of the bump 509 may be designed, so long as the bump 509 can cooperate with the pressing member to perform its function.

Preferably, the second pressing block 508 may be provided with a short shaft, and the protrusion 509 is a bearing mounted on the short shaft.

Note that, the bump 509 in the present application indicates a bump structure, which may be used as a control member for moving the pressing member, and of course, the bump structure may be a bearing disposed on a short shaft of the second pressing member 508, or the bump may be implemented by a hydraulic control mechanism, an electric control mechanism, or the like.

The second guide rod 501 is further sleeved with a lower horizontal plate 503, and the sleeve rod 511 is connected to the lower horizontal plate 503. The distance between the end of the loop bar 511 and the lower horizontal plate 503 is relatively fixed, and may be fixed or detachable.

In addition, a guide post 504 is provided on the lower horizontal plate 503, a sleeve seat 506 is provided at a corresponding position of the upper horizontal plate 505, the guide post 504 passes through the sleeve seat 506 and the top ends are connected by a connecting rod 507. The upper horizontal plate 505 can be moved closer to or farther from the lower horizontal plate 503 by the sleeve mount 506 and the guide post 504.

Optionally, the guide posts 504 may also be one or more, and in this embodiment, two guide posts 504 are provided and are respectively disposed at two ends of the lower horizontal plate 503 to ensure stability and reliability.

In the working process, the lifting movement of the second guide rod 501 can drive the lifting of the upper horizontal plate 505, so as to drive the lifting of the second pressing block 508 connected to the upper horizontal plate 505, and further, the bump 509 installed on the second pressing block 508 is lifted along with the lifting, and the sleeve 511 is installed on the lower horizontal plate 503 and does not move along with the movement of the second guide rod 501, so that the position of the sleeve 511 is fixed relative to the frame 1, the position of the bump 509 is changed relative to the frame 1, and the heat-shrinkable sleeve 6 sleeved on the sleeve 511 can be pushed out from the sleeve 511 and sleeved on an electronic device through the axial movement of the pressing piece along the sleeve 511.

On the basis of the above embodiment, in order to simplify the structure, the pressing member may be a ring member provided with a groove on a side or in the circumferential direction, and the protrusion 509 may be inserted into the groove to drive the pressing member to move by moving itself.

The annular piece is sleeved on the sleeve 511, so that the contact area of the annular piece and the heat-shrinkable sleeve 6 sleeved on the sleeve 511 can be increased, each point on the contact surface is uniformly stressed, and the situation that the heat-shrinkable sleeve 6 is skewed when sleeved on an electronic device due to uneven stress is avoided.

Referring to fig. 3 and 4, the ring member may be a press sleeve 510 with a groove formed in the circumferential direction, and the press sleeve 510 has two stepped surfaces, which respectively provide two contact points or contact surfaces for the cam 509 to drive the press sleeve 510 to move.

On the basis of the above embodiment, in order to realize the movement of the sleeve assembly between the heat-shrinkable sleeve position and the position to be sleeved of the electronic device, a third guide rod 502 connected with the control device is sleeved outside the second guide rod 501, the outer part of the third guide rod 502 is sleeved with the lower horizontal plate 503 and is connected with the lower horizontal plate 503 in a key manner, and the rotation of the lower horizontal plate 503 can be driven by the rotation of the third guide rod 502, so that the sleeve assembly is moved between the heat-shrinkable sleeve position and the position to be mounted of the electronic device.

The third guide rod 502 is sleeved outside the second guide rod 501, and it should be noted that the rotation of the third guide rod 503 does not interfere with the lifting movement of the second guide rod 501.

The third guide bar 502 is coupled with the lower horizontal plate 503 while being coupled by a key so as to be able to transmit torque. Because the sleeve 511 is mounted to the lower horizontal plate 503, rotation of the third guide 502 can rotate the sleeve assembly.

In this embodiment, the third guide rod 502 is sleeved outside the second guide rod 501, so that the third guide rod 502 is sleeved on the lower horizontal plate 503 and connected with the control device through a key, and the control device can drive the sleeve assembly mounted on the lower horizontal plate 503 to rotate through rotation of the third guide rod 502, thereby realizing movement of the sleeve assembly between the heat-shrinkable sleeve position and the position to be mounted of the electronic device.

Alternatively, the third guide bar 502 and the lower horizontal plate 503 may be connected by other means, so as to transmit the steering motion.

On the basis of the above embodiment, in order to make the structure of the clamping member simple and easy to manufacture, the clamping member may be designed as a chuck 44 mounted on the first mount 4 below the short lever 43.
