Description

Technical Field

[0001] This invention relates to the field of network patch cord production equipment technology, and more specifically, to a pre-installation machine for a sheath front-end bracket. Background Technology

[0002] Network patch cords are communication cables used to connect two network devices. Currently, network patch cords on the market include the cable itself and two RJ45 connectors. The rear end of each RJ45 connector is fitted with a sheath front bracket, and the rear end of the sheath front bracket is injection-molded with a sheath. Both ends of the cable pass through the corresponding sheath and sheath front bracket before electrically connecting to the corresponding RJ45 connector. Currently, when injection molding the sheath at the rear end of the sheath front bracket, the front bracket must first be assembled onto a mold base. Then, the mold base is manually placed into the injection mold. The injection molding machine then injection molds the sheath onto the rear end of the front bracket. After injection molding, the mold base is removed from the injection molding machine, and finally, the front bracket of the injection-molded sheath is manually removed from the mold base. However, in the above process, assembling the front bracket of the sheath to be injection molded onto the mold base is done manually, resulting in inconvenience and low assembly efficiency. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a pre-assembly machine for the front end bracket of the sheath, which can facilitate the assembly of the front end bracket of the sheath and the mold base and improve the assembly efficiency.

[0004] This invention provides a pre-assembly machine for sheath front-end brackets, including a frame, a support platform, a feeding mechanism, a translation mechanism, a clamping mechanism, a pushing mechanism, and a mold base for supporting multiple sheath front-end brackets. The support platform is located on one side of the frame. The feeding mechanism and the translation mechanism are both connected to the frame. The clamping mechanism and the pushing mechanism are both connected to the drive end of the translation mechanism. The mold base is placed on the drive end of the translation mechanism. Several horizontally spaced insertion rods are fixed on the mold base. The insertion rods are used to insert into the sheath front-end brackets and support them. The clamping mechanism clamps the mold base onto the drive end of the translation mechanism. The translation mechanism drives the mold base to move horizontally so that the feeding mechanism installs the sheath front-end brackets one by one onto the insertion rods located on the mold base. The pushing mechanism pushes the mold base, after assembling the sheath front-end brackets, onto the support platform.

[0005] By adopting the above structure, the present invention enables the sheath front end brackets to be assembled one by one onto the insert rods located on the mold base in a mechanized manner, thereby facilitating the assembly of the sheath front end brackets and the mold base and improving assembly efficiency.

[0006] In one possible implementation, the translation mechanism includes a linear motor and a movable seat; the linear motor is fixed on the frame, and the movable seat is fixed on the drive end of the linear motor, forming the drive end of the translation mechanism; with this structure, the linear motor can drive the movable seat to move horizontally, thereby enabling the movable seat to reliably drive the clamping mechanism, the pushing mechanism, and the mold base to move horizontally, that is, enabling the mold base to move closer to or away from the support platform, and enabling the feeding mechanism to install the front end bracket of the sheath onto several insert rods located on the mold base one by one.

[0007] In one possible implementation, the mold base is placed on a movable seat, with one end of the mold base abutting against one end of the movable seat. A clamping mechanism is connected to the movable seat, and the clamping end of the clamping mechanism abuts against the other end of the mold base to clamp the mold base onto the movable seat. With this structure, since one end of the mold base abuts against one end of the movable seat, and when the clamping end of the clamping mechanism abuts against the other end of the mold base, the mold base can be clamped onto the movable seat. In addition, the two sides of the mold base can abut against the movable seat, thereby achieving horizontal limiting of the mold base.

[0008] In one possible implementation, the clamping mechanism includes a first cylinder and a clamping block; the first cylinder is fixed on a movable seat, and the clamping block is fixed on the drive end of the first cylinder; when the first cylinder drives the clamping block to move towards the side closer to the mold base, the clamping block abuts against the other end of the mold base to clamp the mold base onto the movable seat; with this structure, since one end of the mold base abuts against one end of the movable seat, when the first cylinder drives the clamping block to move towards the side closer to the mold base, the clamping block can abut against the other end of the mold base to clamp the mold base onto the movable seat; when the first cylinder drives the clamping block to move away from the mold base, the clamping state of the mold base can be released.

[0009] In one possible implementation, the pushing mechanism includes a second cylinder and a push rod; the second cylinder is fixed on a movable seat, one end of the push rod is fixed to the driving end of the second cylinder, and the other end of the push rod is movably inserted through one end of the movable seat; when the clamping mechanism releases the clamping state of the mold base, and the second cylinder drives the push rod to move towards the side closer to the mold base, the push rod is used to push the mold base after assembling the front end bracket of the sheath onto the support platform; with this structure, when the clamping mechanism releases the clamping state of the mold base, and the second cylinder drives the push rod to move towards the side closer to the mold base, the push rod can push the mold base after assembling the front end bracket of the sheath onto the support platform; furthermore, when the second cylinder drives the push rod to move away from the mold base, the push rod can move and reset.

[0010] In one possible implementation, a guide ramp is fixed to the other end of the movable seat; when the jacking mechanism pushes the mold seat toward the support platform, the guide ramp is used to guide the mold seat onto the support platform; by adopting this structure, when the jacking mechanism pushes the mold seat toward the support platform, the guide ramp can guide the mold seat onto the support platform, that is, the guide ramp can guide and direct the movement of the mold seat.

[0011] In one possible implementation, the feeding mechanism includes a vibrating feeder, a conveying track, a third cylinder, and a pusher block. Both the vibrating feeder and the conveying track are fixed to the frame. The feed end of the conveying track is connected to the discharge end of the vibrating feeder. The third cylinder is fixed to one side of the discharge end of the conveying track, and the pusher block is fixed to the drive end of the third cylinder. The vibrating feeder supplies the sheath front-end brackets to the conveying track, and the third cylinder drives the pusher block to reciprocate, causing the pusher block to push out the sheath front-end brackets on the conveying track one by one, and to fit each sheath front-end bracket onto several insert rods located on the mold base. With this feeding mechanism, the vibrating feeder can supply the sheath front-end brackets to the conveying track, and when the third cylinder drives the pusher block to reciprocate, the pusher block can push out the sheath front-end brackets on the conveying track one by one, and the sheath front-end brackets can fit each one onto several insert rods located on the mold base.

[0012] In one possible implementation, the pre-assembly machine for the front end bracket of the sheath further includes a support base and a pushing mechanism; the support base is fixed on the frame, and the pushing mechanism is connected to the frame. The support base is used to support the mold base, and the pushing mechanism is used to push the front end bracket of the sheath located on the insert rod to disengage the front end bracket of the sheath after injection molding from the insert rod. With this structure, after the mold base is placed on the support base, the pushing mechanism can push the front end bracket of the sheath located on the insert rod to disengage the front end bracket of the sheath after injection molding from the insert rod, thus enabling the unloading of the front end bracket of the sheath after injection molding. In addition, the mold base is vertically inserted into the support base and horizontally limited by the support base.

[0013] In one possible implementation, the feeding mechanism includes a fourth cylinder and a sliding seat; the sliding seat is slidably connected to the frame, the fourth cylinder is fixed to the frame and used to drive the sliding seat closer to or away from the support seat, and the sliding seat is connected to the drive end of the fourth cylinder; several push plate groups are fixed on the side of the sliding seat facing the support seat, each push plate group includes two push plates arranged horizontally and symmetrically; when the fourth cylinder drives the sliding seat to move closer to the support seat, the two push plates in each push plate group are used to abut against the two sides of the rear end of the sheath front bracket on the corresponding insert rod and push the sheath front bracket after injection molding off the insert rod; by adopting this feeding mechanism... After the mechanism is activated, when the fourth cylinder drives the sliding seat to move towards the side closer to the support seat, the two push plates in each push plate group can abut against the two sides of the rear end of the front end bracket of the sleeve on the corresponding insert rod and push the front end bracket of the sleeve after injection molding off the insert rod, thereby realizing the unloading of the front end bracket of the sleeve after injection molding. In addition, when the two push plates in each push plate group push the rear end of the front end bracket of the sleeve on the corresponding insert rod, the two push plates in each push plate group are located on both sides of the corresponding insert rod, thereby improving the reliability of pushing the front end bracket of the sleeve after injection molding, so that the front end bracket of the sleeve after injection molding can be disengaged from the insert rod.

[0014] In one possible implementation, the pre-loading machine for the front-end support of the injection-molded sheath further includes a hopper and a hopper; the hopper is fixed to one side of the frame, and the hopper is placed on one side of the frame; the hopper is used to receive the front-end support of the injection-molded sheath pushed off the insert rod and guide the front-end support of the injection-molded sheath into the hopper; with this structure, when the pusher mechanism pushes the front-end support of the injection-molded sheath to discharge the front-end support of the injection-molded sheath, the hopper can receive the front-end support of the injection-molded sheath pushed off the insert rod and guide the front-end support of the injection-molded sheath into the hopper, that is, the hopper can collect the front-end support of the injection-molded sheath.

[0019] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0020] See Figure 1-4 As shown in the figure, this application discloses a pre-assembly machine for sheath front brackets, including a frame 1, a support platform 2, a feeding mechanism 3, a translation mechanism 4, a clamping mechanism 5, a pushing mechanism 6, and a mold base 8 for supporting multiple sheath front brackets 7. The support platform 2 is located on one side of the frame 1. The feeding mechanism 3 and the translation mechanism 4 are both connected to the frame 1. The clamping mechanism 5 and the pushing mechanism 6 are both connected to the drive end of the translation mechanism 4. The mold base 8 is placed on the drive end of the translation mechanism 4. Several horizontally spaced insertion rods 81 are fixed on the mold base 8. The insertion rods 81 are used to insert into the sheath front brackets 7 and support the sheath front brackets 7. The clamping mechanism 5 is used to clamp the mold base 8 on the drive end of the translation mechanism 4. The translation mechanism 4 is used to drive the mold base 8 to move horizontally so that the feeding mechanism 3 will fit the sheath front brackets 7 one by one onto the several insertion rods 81 located on the mold base 8. The pushing mechanism 6 is used to push the mold base 8 after assembling the sheath front brackets 7 onto the support platform 2.

[0021] The translation mechanism 4 includes a linear motor 41 and a movable seat 42. The linear motor 41 is fixed on the frame 1, and the movable seat 42 is fixed on the drive end of the linear motor 41, forming the drive end of the translation mechanism 4. With this structure, the linear motor can drive the movable seat to move horizontally, thereby enabling the movable seat to reliably drive the clamping mechanism, the pushing mechanism, and the mold base to move horizontally. This allows the mold base to move closer to or further away from the support platform, and enables the feeding mechanism to install the front end bracket of the sheath onto several insert rods located on the mold base one by one.

[0022] The mold base 8 is placed on the movable seat 42, with one end of the mold base 8 abutting against one end of the movable seat 42. The clamping mechanism 5 is connected to the movable seat 42, and the clamping end of the clamping mechanism 5 abuts against the other end of the mold base 8 to clamp the mold base 8 onto the movable seat 42. With this structure, since one end of the mold base abuts against one end of the movable seat, and when the clamping end of the clamping mechanism abuts against the other end of the mold base, the mold base can be clamped onto the movable seat. In addition, the two sides of the mold base can abut against the movable seat, thereby achieving horizontal limiting of the mold base.

[0023] The clamping mechanism 5 includes a first cylinder 51 and a clamping block 52. The first cylinder 51 is fixed on the movable seat 42, and the clamping block 52 is fixed on the drive end of the first cylinder 51. When the first cylinder 51 drives the clamping block 52 to move towards the side closer to the mold base 8, the clamping block 52 abuts against the other end of the mold base 8 to clamp the mold base 8 onto the movable seat 42. With this structure, since one end of the mold base abuts against one end of the movable seat, when the first cylinder drives the clamping block to move towards the side closer to the mold base, the clamping block can abut against the other end of the mold base to clamp the mold base onto the movable seat. When the first cylinder drives the clamping block to move away from the mold base, the clamping state of the mold base can be released.

[0024] The pushing mechanism 6 includes a second cylinder 61 and a push rod 62. The second cylinder 61 is fixed on the movable seat 42, one end of the push rod 62 is fixed to the driving end of the second cylinder 61, and the other end of the push rod 62 is movably inserted into one end of the movable seat 42. When the clamping mechanism 5 releases the clamping state of the mold base 8, and the second cylinder 61 drives the push rod 62 to move towards the side closer to the mold base 8, the push rod 62 is used to push the mold base 8 after assembling the front end bracket 7 of the protective sleeve onto the support platform 2. With this structure, when the clamping mechanism releases the clamping state of the mold base, and the second cylinder drives the push rod to move towards the side closer to the mold base, the push rod can push the mold base after assembling the front end bracket of the protective sleeve onto the support platform. In addition, when the second cylinder drives the push rod to move away from the mold base, the push rod can move and reset.

[0025] A guide ramp 43 is fixed to the other end of the movable seat 42; when the pushing mechanism 6 pushes the mold seat 8 toward the support platform 2, the guide ramp 43 is used to guide the mold seat 8 onto the support platform 2; by adopting this structure, when the pushing mechanism pushes the mold seat toward the support platform, the guide ramp can guide the mold seat onto the support platform, that is, the guide ramp can guide and direct the movement of the mold seat.

[0026] The feeding mechanism 3 includes a vibrating feeding plate 31, a conveying track 32, a third cylinder 33, and a pusher block 34. Both the vibrating feeding plate 31 and the conveying track 32 are fixed to the frame 1. The inlet end of the conveying track 32 is connected to the outlet end of the vibrating feeding plate 31. The third cylinder 33 is fixed to one side of the outlet end of the conveying track 32, and the pusher block 34 is fixed to the drive end of the third cylinder 33. The vibrating feeding plate 31 is used to supply the sheath front end bracket 7 into the conveying track 32, and the third cylinder 33 is used to drive the pusher block. The pusher block 34 reciprocates to push out the sheath front end brackets 7 on the conveying track 32 one by one, and puts the sheath front end brackets 7 into the several insert rods 81 located on the mold base 8 one by one. With this feeding mechanism, the vibrating feeder can supply the sheath front end brackets to the conveying track, and when the third cylinder drives the pusher block to reciprocate, the pusher block can push out the sheath front end brackets on the conveying track one by one, and the sheath front end brackets can be put into the several insert rods located on the mold base one by one.

[0027] The pre-assembly machine for the front sleeve support also includes a support base 91 and a pusher mechanism 92. The support base 91 is fixed on the frame 1, and the pusher mechanism 92 is connected to the frame 1. The support base 91 is used to support the mold base 8, and the pusher mechanism 92 is used to push the front sleeve support 7 located on the insert rod 81 so that the front sleeve support 7 after injection molding is detached from the insert rod 81. With this structure, after the mold base is placed on the support base, the pusher mechanism can push the front sleeve support located on the insert rod so that the front sleeve support after injection molding is detached from the insert rod, that is, the front sleeve support after injection molding can be unloaded. In addition, the mold base is vertically inserted into the support base and is horizontally limited with the support base.

[0028] The feeding mechanism 92 includes a fourth cylinder 921 and a sliding seat 922. The sliding seat 922 is slidably connected to the frame 1. The fourth cylinder 921 is fixed to the frame 1 and is used to drive the sliding seat 922 closer to or away from the support seat 91. The sliding seat 922 is connected to the drive end of the fourth cylinder 921. Several push plate groups are fixed on the side of the sliding seat 922 facing the support seat 91. Each push plate group includes two push plates 923 arranged horizontally and symmetrically. When the fourth cylinder 921 drives the sliding seat 922 to move closer to the support seat 91, the two push plates 923 in each push plate group are used to abut against the two sides of the rear end of the sheath front end bracket 7 on the corresponding insert rod 81 and press the front end of the injection-molded sheath. The bracket 7 is pushed off the insert rod 81. By adopting this pushing mechanism, when the fourth cylinder drives the sliding seat to move towards the side closer to the support seat, the two push plates in each push plate group can abut against the two sides of the rear end of the front bracket of the sleeve on the corresponding insert rod and push the front bracket of the sleeve after injection molding off the insert rod, thereby realizing the unloading of the front bracket of the sleeve after injection molding. In addition, when the two push plates in each push plate group push the rear end of the front bracket of the sleeve on the corresponding insert rod, the two push plates in each push plate group are located on both sides of the corresponding insert rod, thereby improving the reliability of pushing the front bracket of the sleeve after injection molding, so that the front bracket of the sleeve after injection molding can be disengaged from the insert rod.

[0029] The pre-loading machine for the front support of the sheath also includes a hopper 10 and a hopper 20; the hopper 10 is fixed to one side of the frame 1, and the hopper 20 is placed on one side of the frame 1; the hopper 10 is used to receive the front support 7 of the injection-molded sheath after being pushed off the insert rod 81 and guide the front support 7 of the injection-molded sheath into the hopper 20; with this structure, when the pusher mechanism pushes the front support of the injection-molded sheath to discharge the front support of the injection-molded sheath, the hopper can receive the front support of the injection-molded sheath after being pushed off the insert rod and guide the front support of the injection-molded sheath into the hopper, that is, the hopper can collect the front support of the injection-molded sheath after being discharged.

[0030] When using this invention, firstly, the mold base with insert rods is placed on the movable seat in the translation mechanism. Then, the clamping mechanism clamps the mold base onto the movable seat. Next, the feeding mechanism supplies the front end bracket of the sheath, and in conjunction with the translation mechanism, moves the mold base horizontally so that the front end brackets of the sheath are fitted one by one onto each insert rod on the mold base (the distance the translation mechanism moves the mold base horizontally each time is the distance between two insert rods). After all insert rods are fitted with the front end brackets of the sheath, the translation mechanism moves the mold base back to its original position, and the clamping mechanism releases the clamping of the mold base. Then, the pushing mechanism pushes the mold base with the front end brackets of the sheath onto the support platform. At this point, the operator can remove the mold base with the front end brackets of the sheath and place it into the injection mold. The injection molding machine then injection molds the sheath onto the rear end of the front end bracket. After injection molding is complete, the operator removes the mold base from the injection molding machine. The mold base can be inserted into the support base, and the ejector mechanism can push the front end bracket of the molded sleeve on the insert rod to detach it from the insert rod, thus enabling the unloading of the front end bracket of the molded sleeve. Simultaneously, the hopper can receive the front end bracket of the molded sleeve pushed off the insert rod and guide it into the hopper, thus enabling the hopper to collect the front end bracket of the molded sleeve. By adopting the above structure, this invention allows for the mechanized assembly of the front end brackets of the mold base onto the insert rod one by one, facilitating the assembly of the front end brackets and improving assembly efficiency. Furthermore, this invention also allows for the mechanized pushing of the front end brackets of the molded sleeve off the mold base, facilitating unloading and saving labor.

[0031] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
