Description

TECHNICAL FIELD

[0001] The utility model relates to contactor assembly technical field, concretely relates to a locking screw machine of coil. BACKGROUND

[0002] As an indispensable electrical component in the power control system, the core function of the AC contactor is to realize the remote control of the power equipment by controlling the on-off of the circuit. As a key component of the AC contactor, the coil not only bears the heavy responsibility of generating a magnetic field to drive the contact to close or open, but also ensures the accurate transmission of the control signal through electrical connection with external wires. The realization of this electrical connection depends on the tile screw locked on the contactor housing. The unique tile design of the tile screw not only provides a stable mechanical connection, but also ensures the reliability of the electrical connection. However, this special design also brings some challenges to the automation of locking.

[0003] The existing locking screw machine generally uses a vibration disc for automatic feeding, then uses a suction device to suck and lift the screw from the discharge end of the vibration disc, and then moves it to the threaded hole to be installed. Finally, through the rotation of the screwdriver head, the screw is locked into the corresponding threaded hole. However, the existing locking screw machine is often designed for standard screws, and the suction device often cannot adapt to the special shape and size of the tile screw, making it difficult for the suction device to effectively suck. Even if it can be sucked, it may fall off during the moving process due to unstable suction, thereby affecting the accuracy and efficiency of locking. And the existing locking screw machine can only load one screw at a time, which will undoubtedly greatly reduce the production efficiency when dealing with AC contactors that require a large number of screws to be locked.

[0004] Therefore, in view of the challenges of AC contactor coil fixation and tile screw automation locking, it is necessary to develop a locking screw machine for coils to ensure the stable operation and reliable connection of AC contactors. UTILITY MODEL CONTENTS

[0041] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0042] The present application provides a coil screw locking machine, which is used to solve the problem of how to feed tile screws 200 and improve the feeding efficiency of tile screws 200.

[0043] Referring to Figure 1 , Figure 3 , Figure 4 and Figure 5 , it is shown that Figure 1 is a perspective view of the coil screw locking machine in the embodiment, Figure 3 is a perspective view of the material taking rod in the first position in the embodiment, Figure 4 is Figure 3 an enlarged schematic view of B, Figure 5 is a perspective view of the material taking rod in the second position in the embodiment, and the coil screw locking machine comprises a workbench 1, a feeding rack 2, a material taking rod 3, a driving mechanism 4 and a locking mechanism 5.

[0044] The workbench 1 is used for carrying and positioning the contactor shell 100.

[0045] The feeding rack 2 is installed on one side of the workbench 1, and the feeding rack 2 has at least one feeding channel 21 for conveying the tile screw 200.

[0046] The taking rod 3 has a limiting groove 31, the number of the limiting groove 31 is the same as that of the feeding channel 21, and the limiting groove 31 is used for accommodating the screw rod part of the tile screw 200.

[0047] The driving mechanism 4 is installed between the workbench 1 and the feeding rack 2, and is in transmission connection with the taking rod 3, and the driving mechanism 4 is used for driving the taking rod 3 to reciprocate between the first position and the second position.

[0048] The locking mechanism 5 is installed above the workbench 1, and the locking mechanism 5 is used for locking the tile screw 200 on the contactor shell 100 on the workbench 1.

[0049] The taking rod 3 is in the first position, and the slot of the limiting groove 31 is in butt joint with the feeding channel 21 of the feeding rack 2; and the taking rod 3 is in the second position, and the limiting groove 31 is located directly below the locking mechanism 5, so that the tile screw 200 is coaxially arranged with the threaded hole 101 on the contactor shell 100.

[0050] In use of the coil locking screw machine, the original position of the taking rod 3 is the first position, first, the feeding rack 2 inputs one tile screw 200 in each feeding channel 21 into the corresponding limiting groove 31; then, the driving mechanism 4 drives the taking rod 3 to move to the second position, so as to transfer the tile screw 200 to be directly below the locking mechanism 5, so that the tile screw 200 is coaxially arranged with the threaded hole 101 on the contactor shell 100; finally, the locking mechanism 5 locks the tile screw 200 in the corresponding threaded hole 101, and the driving mechanism 4 drives the taking rod 3 to return to the original position. It can be seen that the coil locking screw machine can replace manual feeding of the tile screw 200 through cooperation of the feeding rack 2, the taking rod 3 and the driving mechanism 4, and the number of the feeding channel 21 and the limiting groove 31 can be set according to the number of the tile screw 200 that needs to be fed at the same time, and at least one tile screw 200 can be fed at the same time through cooperation of at least one feeding channel 21 and limiting groove 31, so that the feeding efficiency of the tile screw 200 is effectively improved.

[0051] The coil locking screw machine can not only feed the tile screw 200, but also feed the standard screw through the limiting groove 31, so that the application range is wide.

[0052] The slot of the limiting slot 31 of the above-mentioned material taking rod 3 can be designed as a fixed size of the gradually expanding port 32, the caliber of the gradually expanding port 32 gradually increases along the radial direction of the limiting slot 31, in this way, the design of the gradually expanding port 32 can facilitate the input of the tile screw 200 into the limiting slot 31; or the slot of the above-mentioned limiting slot 31 can also be designed as a mechanically openable and closable slot size changeable or slot opening and closing changeable way, which can also facilitate the input of the tile screw 200 into the limiting slot 31.

[0053] Referring to Figure 1 and Figure 5 , in one embodiment of the driving mechanism 4, the driving mechanism 4 includes a first rotary driving member 41 and a linear displacement driving member 42, the first rotary driving member 41 is installed on the output end of the linear displacement driving member 42, and the output end of the first rotary driving member 41 is connected with the material taking rod 3. In this way, when the tile screw 200 is fed, the original position of the material taking rod 3 is the first position, after the feeding rack 2 inputs the tile screw 200 into the corresponding limiting slot 31, the linear displacement driving member 42 drives the first rotary driving member 41 and the material taking rod 3 to move a small distance away from the feeding rack 2, then the first rotary driving member 41 drives the material taking rod 3 to rotate, so that the slot of the limiting slot 31 faces the workbench 1; then, the linear displacement driving member 42 drives the first rotary driving member 41 and the material taking rod 3 to move a small distance towards the workbench 1, so as to move the material taking rod 3 to the second position, so that the tile screw 200 is coaxially arranged with the threaded hole 101 on the contactor housing 100; when the tile screw 200 is locked, the linear displacement driving member 42 drives the first rotary driving member 41 and the material taking rod 3 to move a small distance away from the workbench 1, the first rotary driving member 41 drives the material taking rod 3 to rotate in the opposite direction, and the linear displacement driving member 42 drives the first rotary driving member 41 and the material taking rod 3 to move a small distance towards the feeding rack 2 again, thereby driving the material taking rod 3 to return to the first position. It can be seen that the driving mechanism 4 can realize the transfer feeding of the tile screw 200 through the cooperation of the first rotary driving member 41 and the linear displacement driving member 42, wherein the driving mechanism 4 can effectively avoid the interference between the material taking rod 3 and the material blocking rod 7, the feeding rack 2 or the contactor housing 100 during the rotation of the material taking rod 3.

[0054] The above-mentioned first rotary driving member 41 can use the existing rotary driving motor or rotary cylinder and other rotary driving mechanisms 4, and the linear displacement driving member 42 can use the existing telescopic cylinder or linear motor and other linear displacement driving mechanisms 4. The output end of the first rotary driving member 41 can be detachably connected with the material taking rod 3, so as to facilitate the replacement of the material taking rod 3 with different diameters of limiting slots 31 according to the specifications of the tile screw 200.

[0055] Referring to Figure 1 , Figure 3 and Figure 5As shown, on the basis of the above embodiment, one end of the material taking rod 3 is swingably connected to the output end of the first rotary driving member 41, and the other end has the limiting slot 31 described above. The driving mechanism 4 further comprises a resilient member 43, both ends of the resilient member 43 are connected to the output end of the first rotary driving member 41 and the material taking rod 3 respectively, and the resilient member 43 is used to drive the material taking rod 3 to be horizontally arranged, or to drive the material taking rod 3 to have one end with the limiting slot 31 to be arranged obliquely upward. In this way, under the condition that the material taking rod 3 is not subjected to external force, the elastic force of the resilient member 43 can pull the material taking rod 3 to rotate upward to be horizontally arranged, or to pull the material taking rod 3 to have one end with the limiting slot 31 to be arranged obliquely upward, so as to prevent the tile screw 200 from sliding out of the limiting slot 31 in the process that the driving mechanism 4 drives the material taking rod 3 to shift the tile screw 200, thereby affecting the subsequent locking action. When the driving mechanism 4 drives the material taking rod 3 to move to the second position, the output end of the locking mechanism 5 is downwardly connected with the tile screw 200, and overcomes the elastic force of the resilient member 43, so that the shank part of the tile screw 200 can be screwed into the threaded hole 101 by a certain depth downwardly, then the driving mechanism 4 drives the material taking rod 3 to leave the second position, and the output end of the locking mechanism 5 continues to downwardly lock the tile screw 200 further. It can be seen that, in the initial stage of locking, the material taking rod 3 can limit the tile screw 200 at the second position, and effectively avoids the tile screw 200 from falling off the threaded hole 101 in the process of locking.

[0056] Referring to Figure 1 As shown, the tile screw locking machine of the coil further comprises a vibrating disc 6, the discharging end of the vibrating disc 6 is butted and communicated with the feeding channel 21 of the feeding rack 2, and is used to continuously supply the tile screws 200 for the feeding channel 21. In this way, the tile screw locking machine of the coil can continuously transport the tile screws 200 one by one through the cooperation of the vibrating disc 6 and the feeding channel 21, and further improves the feeding efficiency of the tile screws 200.

[0057] Referring to Figure 1 and Figure 3 As shown, on the basis of the above embodiment, the tile screw locking machine of the coil further comprises a material blocking rod 7 and a material blocking rod driving mechanism 8 in transmission connection with the material blocking rod 7, and the material blocking rod driving mechanism 8 is used to drive the material blocking rod 7 to move towards or away from the discharging end of the feeding channel 21. In this way, when the driving mechanism 4 drives the material taking rod 3 to move from the first position to the second position, the material blocking rod driving mechanism 8 drives the material blocking rod 7 to move to the discharging end of the feeding channel 21, so as to block the discharging end of the feeding channel 21, and avoid the remaining tile screws 200 from being output from the feeding channel 21, thereby causing waste. Conversely, when the driving mechanism 4 drives the material taking rod 3 to return from the second position to the first position, the material blocking rod driving mechanism 8 drives the material blocking rod 7 to move away from the discharging end of the feeding channel 21, so as to provide a space, and thus facilitate the slot opening of the limiting slot 31 of the material taking rod 3 to butt and take material from the feeding channel 21.

[0058] The above-mentioned material blocking rod driving mechanism 8 can use a linear displacement driving mechanism such as an existing telescopic pneumatic cylinder or a linear motor. The material blocking rod driving mechanism 8 can drive the material blocking rod 7 to move up and down towards the discharge end of the feeding channel 21, so as to block or expose the discharge end of the feeding channel 21, or drive the material blocking rod 7 to slide left and right towards the discharge end of the feeding channel 21, so as to block or expose the discharge end of the feeding channel 21. The movement direction of the material blocking rod 7 is not limited too much, as long as the opening and closing of the discharge end of the feeding channel 21 can be controlled.

[0059] Referring to Figure 1 As shown in the drawings, in one embodiment of the locking mechanism 5, the locking mechanism 5 includes a screwdriver 51, a second rotary driving member 52, and a lifting driving member 53. The second rotary driving member 52 is installed on the output end of the lifting driving member 53, and the output end of the second rotary driving member 52 is fixedly connected with the screwdriver 51 by screwing or welding, and the number of the screwdriver 51, the second rotary driving member 52, and the limiting groove 31 is the same. As can be seen, the locking mechanism 5 can drive several second rotary driving members 52 and screwdrivers 51 to move up and down together through the lifting driving member 53, and drive the screwdriver 51 to rotate through the second rotary driving member 52, so as to realize the synchronous screw lifting of several screwdrivers 51. In this way, the locking mechanism 5 can simultaneously lock multiple tile screws 200 on the same plane of the product, greatly improving the production efficiency.

[0060] Referring to Figure 1 and Figure 5 As shown in the drawings, in one embodiment of the workbench 1, the workbench 1 has a conveying channel 11 for carrying several contactor housings 100 and conveying them in sequence to the locking mechanism 5 directly below. One side of the workbench 1 is provided with a positioning clamp 12, which is opposite to the locking mechanism 5. When the locking mechanism 5 locks the tile screws 200, the positioning clamp 12 is used to position the contactor housing 100, so as to fix the contactor housing 100 directly below the locking mechanism 5. In this way, the positioning clamp 12 can fix the position of the contactor housing 100, ensuring the stability and accuracy of the screw locking process.

[0061] The conveying channel 11 can be provided on a conveying mechanism such as a conveying belt, a conveying chain, or a indexing disc, and the contactor housing 100 on the conveying channel 11 is conveyed by the conveying mechanism as a driving source.

[0062] As Figure 5As shown, the positioning clamp 12 can use the clamping jaw cylinder which can be swung outwardly to open and swung inwardly to clamp. Thus, after the tile screw 200 is locked, the clamping jaw 121 is swung outwardly to open, so that the contactor shell 100 can be conveniently moved out of the positioning clamp 12 along the conveying channel 11, and the next contactor shell 100 to be screwed can be conveniently moved into the positioning clamp 12. The conveying belt can be arranged in the conveying channel 11, so as to automatically convey the contactor shell 100 to move in and out of the positioning clamp 12.

[0063] Referring to Figure 1 and Figure 5 As shown, the coil screw locking machine further comprises a first detection member 91 installed on one side of the workbench 1 and opposite to the position of the locking mechanism 5, for detecting whether there is a contactor shell 100 below the locking mechanism 5. If not, the worker can be timely warned, so as to effectively avoid affecting the subsequent locking operation.

[0064] Referring to Figure 1 and Figure 5 As shown, the coil screw locking machine further comprises a second detection member 92 installed on the discharge end of the feeding channel 21, for detecting whether the tile screw 200 is output from the feeding channel 21. If not, the worker can be timely warned, so as to effectively avoid affecting the subsequent locking operation and avoiding the situation that the contactor product is missing the screw locking.

[0065] Referring to Figure 1 and Figure 5 As shown, the coil screw locking machine further comprises a third detection member 93 installed on one side of the workbench 1, for detecting whether the tile screw 200 is installed on the contactor shell 100, so as to effectively avoid affecting the subsequent locking operation.

[0066] The first detection member 91, the second detection member 92 and the third detection member 93 can use the existing photoelectric sensor or infrared sensor.

[0067] Although the embodiments of the present application have been shown and described, it should be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
