Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0020] As described in the background technology, traditional spring assembly methods mostly rely on manual operation or semi-automatic equipment, which not only increases labor intensity, but may also lead to problems such as insufficient assembly precision and low production efficiency. In the existing spring automatic assembly equipment solution, the spring enters the transmission tube from the vibration plate and is transmitted from the transmission tube to the assembly mechanism. In this transmission method, multiple springs will enter the transmission tube, which will cause other springs to pull the assembled spring, causing the spring to deform or not be installed in place, affecting the assembly quality of the spring.

[0021] In order to solve this technical problem, the present invention provides a spring automatic assembly device, which is applied to the field of automatic assembly.

[0022] Specifically, please refer to Figure 2-18 , the spring automatic assembly device specifically comprises: A feeding mechanism 1, which includes a discharge pipe 102; The material transfer mechanism 2 includes a material transfer seat 201, a slide bar 202 and a transition plate 205 arranged side by side. The transition plate 205 and the slide bar 202 are respectively provided with a channel 1 206 and a channel 2 207. The channel 1 206 is docked with the discharge pipe 102. The material transfer seat 201 is provided with an upper pipe head 208 staggered with the channel 1 206. The discharge pipe 102 delivers the spring 300 to the channel 2 207 through the channel 1 206. The slide bar 202 slides to dock the channel 2 207 with the upper pipe head 208. The pushing mechanism 3 is used to push the spring 300 in the second channel 207 on the sliding bar 202 into the upper pipe head 208; A feeding mechanism 4, comprising a feeding pipe 401, wherein the feeding pipe 401 is connected to the upper pipe head 208; The assembly mechanism includes an assembly seat 501 and an assembly plate 502, wherein the assembly plate 502 is provided with a lower tube head 505 connected to the feeding tube 401, the assembly plate 502 is slidably connected to the assembly seat 501 and the assembly seat 501 is provided with a discharge hole 506 matching the lower tube head 505. When assembling, the lower tube head 505 on the assembly plate 502 is docked with the discharge hole 506. When not assembling, the assembly plate 502 moves so that the lower tube head 505 and the discharge hole 506 are staggered.

[0023] The spring automatic assembly device provided by the present invention conveys the spring 300 through the discharge pipe 102, and after passing through the channel 1 206 in the transition plate 205, it vibrates and moves to the channel 2 207 of the sliding bar 202, the sliding bar 202 moves to dock the channel 2 207 with the upper tube head 208, and the spring 300 is pushed into the upper tube head 208 by the pushing mechanism 3, and the spring 300 enters the feeding pipe 401 from the upper tube head 208 and slides along the feeding pipe 401 to the lower tube head 505, and enters the workpiece to be assembled through the discharge hole 506, completing the assembly of the spring 300, realizing the automatic assembly of the spring 300, and improving the production efficiency. The setting of the sliding bar 202 makes it possible to convey only a single spring 300 at a time, avoiding pulling between the springs 300, ensuring that the spring 300 can be installed in place, with high assembly accuracy, and improving the assembly quality of the spring 300.

[0024] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings.

[0025] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions in the embodiments may be combined with each other.

[0026] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0027] Embodiment 1 Please refer to Figure 2-4 , provides a spring automatic assembly device, which includes a loading mechanism 1, a transfer mechanism 2, a pushing mechanism 3, a feeding mechanism 4 and an assembling mechanism 5. The loading mechanism 1 feeds the spring 300 into the transfer mechanism 2, and the transfer mechanism 2 cooperates with the pushing mechanism 3 to transport the single spring 300 to the feeding mechanism 4. The feeding mechanism 4 feeds the spring 300 onto the assembling mechanism 5, and the assembling mechanism 5 is used to load the spring 300 into the workpiece to complete the assembly of the spring 300.

[0028] Specifically, Figure 1 As shown, an existing housing 100 is provided with mounting grooves 200 on both sides of the inner ends of the housing 100. Springs 300 need to be installed at both ends of the mounting grooves 200. The automatic assembly device of the present invention is specifically described by assembling the spring 300 of the housing 100.

[0029] like Figure 5 As shown, the feeding mechanism 1 includes two symmetrically arranged vibration disks 101, which are fixed on the frame. The discharging rotation directions of the two vibration disks 101 are opposite, and the outlets of the two vibration disks 101 are fixedly connected to two upper and lower distributed discharging pipes 102 to form two discharging channels. When the vibration disk 101 is started, the spring 300 moves along the rotating track inside the vibration disk 101 into the discharging pipe 102, and is discharged from the discharging pipe 102 during the vibration process, and a wire groove 103 is provided at the discharging end of the discharging pipe 102. The provision of the wire groove 103 is convenient for observing whether the spring 300 is delivered into place on the one hand, and is also convenient for blocking the discharge of the spring 300 on the other hand.

[0030] like Figure 6-11As shown, the material transfer mechanism 2 is arranged on one side of the feeding mechanism 1, and the material transfer mechanism 2 includes a material transfer seat 201. Two slideways are provided on the side of the material transfer seat 201 close to the vibration plate 101, and sliding bars 202 are slid in the two slideways. The thickness of the sliding bar 202 is consistent with the depth of the slideway. A cylinder 203 is fixedly installed on one side of the material transfer seat 201, and the telescopic end of the cylinder 203 is fixedly connected to a clamp seat 204. One end of the two sliding bars 202 are fixedly connected to the clamp seat 204, and the cylinder 203 drives the sliding bar 202 to slide along the material transfer seat 201. A transition plate 205 is provided on one side of the transfer base 201 close to the vibration plate 101. The transition plate 205 is fixed on the frame. Four channels 1 206 are arranged in a matrix. Two channels 207 are arranged on each sliding bar 202. The distance between the two channels 207 is the same as the distance between the two transverse channels 1 206. Four upper tube heads 208 are arranged in a matrix on the transfer base 201. One end of the upper tube head 208 extends into the slideway. The upper tube head 208 is staggered with the channel 2 207, and the sliding bar 202 is provided with two channels 207. The moving distance of the strip 202 is the same as the offset distance between the upper tube head 208 and the channel 2 207. The discharge tube 102 vibrates to input the spring 300 into the channel 1 206, and uses the push of the rear spring 300 to push the front spring 300 into the channel 2 207 of the sliding strip 202. Then the cylinder 1 203 pushes the sliding strip 202 to move along the slideway, so that the channel 2 207 is coaxial with the upper tube head 208, and uses the pushing mechanism 3 to send the spring 300 from the channel 2 207 into the upper tube head 208 to complete the feeding.

[0031] like Figure 3 , 8 As shown, the pushing mechanism 3 is used to push the spring 300 in the second channel 207 on the transition plate 205 into the upper tube head 208, and the spring 300 enters the feeding mechanism 4 through the upper tube head 208. Specifically, in this example, the pushing mechanism 3 is a blowing structure, and the blowing mechanism includes an air pump and a blowing pipe 301. The blowing pipe 301 is fixed on the transition plate 205, and the blowing pipe 301 is coaxially arranged with the upper tube head 208. The air pump is connected to the blowing pipe 301 and an electric air valve is arranged. The electric air valve is used to control the air intake amount and air intake time. The blowing pipe 301 is used to blow high-pressure gas into the upper tube head 208, and the spring 300 is blown from the second channel 207 into the upper tube head 208, and a certain power can be provided to the spring 300, so that the spring 300 can enter the feeding mechanism 4 from the upper tube head 208. Of course, other pushing mechanisms 3 may also be used, such as a cylinder driving a push rod, and the push rod is used to push the spring 300 into the upper tube head 208. The push rod can be a hard rod or a flexible rod.

[0032] like Figure 3 , Fig.16As shown, the feeding mechanism 4 includes a feeding tube 401, and there are four feeding tubes 401 and they correspond one to one with the upper tube head 208. The feeding tube 401 is an arc structure. Specifically, the feeding tube 401 is a 90° arc segment, and straight tubes 402 are provided at both ends of the feeding tube 401. The other end of the upper tube head 208 extends out of the transfer seat 201 and the extended part is slidably inserted into the straight tube 402 of the feeding tube 401, and the inner diameter of the arc segment of the feeding tube 401 is the same as the inner diameter of the upper tube head 208, ensuring that the spring 300 can smoothly slide from the upper tube head 208 into the arc segment of the feeding tube 401, and slide out from the lower end into the assembly mechanism 5.

[0033] like Figure 16-18 As shown, the assembly mechanism 5 includes an assembly seat 501 and an assembly plate 502, the assembly seat 501 is fixed on the frame, the assembly plate 502 is slidably connected to the assembly seat 501, and a cylinder 3 503 is fixedly connected to the assembly seat 501, the telescopic shaft of the cylinder 3 503 is fixedly connected to the assembly plate 502 through a connector 504, the cylinder 3 503 drives the assembly plate 502 to slide back and forth on the assembly seat 501, and four lower pipe heads 505 are inserted and installed on the assembly plate 502, and the lower pipe heads 505 correspond to the feeding pipes 401 one by one. During installation, the lower tube head 505 is plugged into the lower end straight tube 402 of the feeding tube 401 and the inner diameter of the lower tube head 505 is consistent with the inner diameter of the arc section of the feeding tube 401. The lower port of the lower feeding tube is flush with the lower surface of the assembly plate 502. Four discharge holes 506 are arranged on the assembly seat 501. The discharge holes 506 are matched with the lower tube head 505. When the cylinder 3 503 drives the assembly plate 502 to move forward and backward, the lower tube head 505 on the assembly plate 502 and the discharge holes 506 are adjusted between alignment and offset. Specifically, during assembly, the lower tube head 505 on the assembly plate 502 is docked with the discharge holes 506 and coaxially arranged. When not assembled, the assembly plate 502 moves so that the lower tube head 505 and the discharge holes 506 are offset to prevent the spring 300 from falling out of the discharge holes 506. The discharge end of the feed tube 401 is arranged tangent to the lower tube head 505 to ensure that the spring 300 can slide smoothly into the lower tube head 505. At the same time, the lower tube head 505 is placed vertically so that the spring 300 can automatically fall into the mounting groove 200 in the housing 100 under the action of gravity, and a positioning block 507 is provided between the two discharge holes 506 corresponding to the mounting groove 200 on the same side of the housing 100 on the bottom surface of the assembly seat 501, which is used to position the installation of the spring 300 so that the spring 300 can accurately fall to the outside of the spring 300 column on both sides of the mounting groove 200 to complete the assembly of the spring 300 into the housing 100.

[0034] It is worth mentioning that in the assembly mechanism 5, a sensor unit for positioning the housing 100, such as a laser sensor, a proximity sensor or an infrared sensor, etc., and a PLC control system are also provided below the assembly plate 501. These parts are all existing conventional technologies and can be designed and used by oneself according to the usage function, and will not be described in detail here.

[0035] Embodiment 2 The spring automatic assembly device provided in the first embodiment is further optimized. Specifically, Figure 8 , 9 As shown in Figures 13, 14, and 15, in order to prevent the spring 300 from being pushed all the time and causing the spring 300 to abut against the sliding bar 202, when the sliding bar 202 moves back and forth, the spring 300 is damaged, and the quality of the spring 300 is affected. For this reason, a stop mechanism 6 is also provided. The stop mechanism 6 includes an L frame 601 fixed on the frame, and the L frame 601 extends to the top of the transition plate 205. A cylinder 2 602 is fixed on the L frame 601. A mounting seat 603 is fixedly connected to the telescopic shaft of the cylinder 202. Two guide columns 604 are fixedly connected to the mounting seat 603. The guide columns 604 are slidably connected to the transition plate 205. The cylinder 2 602 drives the mounting seat 603 to move up and down, and the guide columns 604 are used to maintain the lifting stability and accuracy of the mounting seat 603. Both ends of the mounting seat 603 are fixedly connected with stop blocks 605, and two protruding blocks 606 of different sizes and triangular structures are provided on the stop block 605. The two protruding blocks 606 are vertically distributed, and a stop piece 607 is fixed on the protruding block 606. The transition plate 205 is located above each channel 1 206 and is provided with a triangular structure insertion groove 209. The protruding block 606 extends into the insertion groove 209, and the insertion groove 209 is connected to the channel 1 206 through a gap 210. When the cylinder 2 602 drives the mounting seat 603 to move downward, the stop piece 607 is inserted into the channel 1 206 from the gap 210. The stop piece 607 presses the spring 300 in the channel 1 206 to prevent the spring 300 from vibrating, thereby pressing and fixing the spring 300 to prevent the spring 300 from escaping from the channel 2 207.

[0036] Embodiment 3 The spring automatic assembly device provided in the second embodiment is further optimized. Specifically, Figure 8 , 11As shown, the material transfer mechanism 2 also includes a sliding seat 211 fixed on the frame, the material transfer seat 201 is slidably connected to the sliding seat 211, the transition plate 205 has a groove at the lower end and the two sides cross the sliding seat 211 and are fixed to the frame, the material transfer seat 201 can pass through the groove at the lower end of the transition plate 205, and a cylinder four 212 is fixedly connected to the side of the sliding seat 211 close to the vibration plate 101, and the telescopic shaft of the cylinder four 212 is fixedly connected to a clamping block 213, and the clamping block 213 is clamped with one side of the material transfer seat 201, and the telescopic shaft of the cylinder four 212 drives the clamping block 213 to move, thereby driving the material transfer seat 201 to slide, so that the material transfer seat 201 is close to or away from the transition plate 205, and the thickness of the sliding bar 202 is greater than or equal to the length of a single assembled spring 300, so as to avoid the spring 300 in the channel one 206 also extending into the channel two 207 after the spring 300 is installed in the channel two 207. When it is necessary to feed the spring 300 from channel one 206 to channel two 207, the cylinder four 212 drives the transfer seat 201 to move toward the transition plate 205, so that the transition plate 205 fits with the sliding bar 202, and the stop piece 607 disengages from the gap 210, so that the spring 300 enters the channel two 207 from the channel one 206, and then the stop piece 607 presses down the spring 300 behind, and then the cylinder four 212 drives the transfer seat 201 to move away from the transition plate 205, so that a gap is left between the transition plate 205 and the sliding bar 202, so that the spring 300 in the channel one 206 and the spring 300 in the channel two 207 are far away from each other and do not contact each other, so that when the sliding bar 202 slides, the springs 300 will not be pulled and deformed, thereby ensuring the feeding stability of the spring 300, and the reciprocating operation is performed in this way.

[0037] The working principle of the spring automatic assembly device provided by the present invention is as follows: The spring 300 to be assembled is placed in the two vibration plates 101 respectively, and the vibration plates 101 are started. During the vibration process of the vibration plates 101, the spring 300 is vibrated and discharged from the two discharge pipes 102 along the track, and enters the channel 1 206 of the transition plate 205, and then enters the channel 2 207 of the two sliding bars 202. After the spring 300 completely enters the channel 207, the cylinder 2 602 drives the mounting seat 603 to descend so that the stopper 607 passes through the gap 210 and presses down the channel The spring 300 in the first channel 206 is pushed away from the transition plate 205 by the cylinder 4 212, so that the spring 300 in the second channel 207 is away from the spring 300 in the first channel 206 and does not contact each other. The cylinder 1 203 pushes the slide bar 202 to move along the slideway, so that the second channel 207 is coaxial with the upper tube head 208. The blowing structure blows the spring 300 in the second channel 207 into the upper tube head 208 and uses air pressure to push the spring 300 from the upper tube head 208 into the feeding tube 40. 1, the spring 300 slides into the lower pipe head 505 along the feeding pipe 401 under the action of air pressure and gravity. At this time, the lower pipe head 505 is staggered with the discharge hole 506. The housing 100 is fed to the bottom surface of the assembly seat 501 by a manipulator or a conveying mechanism, and the positioning block 507 is inserted into the mounting groove 200 of the housing 100. The cylinder 3 503 drives the assembly plate 502 to slide on the assembly seat 501, so that the lower pipe head 505 is coaxial with the discharge hole 506. At this time, the four springs 300 are released from the discharge hole 506. 06 fall down at the same time and enter the designated installation position of the housing 100, completing the assembly of the spring 300, realizing the automated assembly of the spring 300, and being able to assemble four springs 300 at the same time, greatly improving the assembly efficiency and production efficiency of the spring 300, reducing the labor intensity, and the setting of the sliding bar 202 allows only a single spring 300 to be transported each time, avoiding pulling between the springs 300, ensuring that the spring 300 can be installed in place, with high assembly accuracy, and improving the assembly quality of the spring 300.
