[0043] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0044] like Figures 1 to 7As shown, this embodiment provides a shaft parts assembly device, which is used to assemble a first workpiece 1000 of an axial structure into the shaft hole 2100 of the second workpiece 2000 in the assembly position, and improve the assembly efficiency through an automated assembly process. The shaft parts assembly device includes a first feeding component 100, a transfer component 200 and a detection component 300. Among them, the first feeding component 100 includes a material separation component and a material receiving component. The material separation component has a discharge port with an opening facing downward to supply the first workpiece 1000. The material receiving component includes a material receiving bracket 110, a material receiving member 120 and a material receiving drive member 130. The material receiving member 120 is provided with a material receiving trough 121. The material receiving member 120 is rotatably provided on the material receiving bracket 110. The material receiving drive member 130 is used to drive the material receiving member 120 to rotate so that the opening of the material receiving trough 121 faces upward to receive the first workpiece 1000 that falls from the discharge port, or opens The mouth faces downward to move the first workpiece 1000 in the receiving trough 121 out; the transfer assembly 200 includes a transfer base 210 and a transfer member 220, the transfer member 220 is provided with a transfer hole 221, the transfer member 220 is rotatably arranged on the transfer base 210, so that the transfer hole 221 moves below the receiving trough 121, between the detection position and the assembly position, and the transfer base 210 is provided with a drop avoidance notch at the assembly position; the detection assembly 300 is used to detect the front and back of the first workpiece 1000 in the transfer hole 221 located at the detection position.

[0045] The arrangement of the receiving member 120 can cushion the impact generated when the first workpiece 1000 falls, prevent the first workpiece 1000 from directly contacting the second workpiece 2000, ensure the structural integrity of the second workpiece 2000, and improve the assembly yield rate.

[0046] In addition, when the material receiving part 120 rotates to the point where the opening of the material receiving groove 121 faces downward, the first workpiece 1000 is transferred to the transfer hole 221 of the transfer part 220 and contacts the transfer base 210. When the transfer part 220 rotates to the detection position, the front and back of the first workpiece 1000 can be detected through the detection component 300. When the transfer part 220 rotates to the assembly position, the first workpiece 1000 falls through the blanking avoidance gap into the axial hole 2100 of the second workpiece 2000.

[0047] In the prior art, the first workpiece 1000 falling from a height will impact the transfer base 210 and produce a pit, so that the first workpiece 1000 in the transfer hole 221 is partially inserted into the pit, causing the transfer part 220 to be locked, making it unable to rotate normally or the power is too large, causing the first workpiece 1000 to bend, resulting in waste.

[0048] With the help of the buffering effect of the material receiving member 120, the first workpiece 1000 is effectively prevented from impacting the transfer base 210 and causing pits, thereby ensuring the flatness of the transfer base 210 and ensuring that the first workpiece 1000 located in the transfer hole 221 can slide smoothly on the top surface of the transfer base 210 during the rotation of the transfer member 220.

[0049] In this embodiment, the hardness of the material receiving member 120 is greater than the hardness of the transfer base 210. In some embodiments, the hardness of the material receiving member 120 is greater than the hardness of the transfer base 210 and greater than the hardness of the second workpiece 2000.

[0050] During the rotation of the material receiving piece 120, in order to prevent the first workpiece 1000 from moving out of the material receiving trough 121 under the action of inertia, the material receiving bracket 110 is provided with an arc-shaped shielding portion, which is arranged around the outer periphery of the material receiving piece 120. The shielding portion is arranged to block the opening of the material receiving trough 121 when the opening of the material receiving trough 121 is located in a position other than upward and downward.

[0051] Combine Figure 5 and Figure 6 As shown, specifically, the material receiving bracket 110 is provided with a material receiving sleeve 140, and the side wall of the material receiving sleeve 140 is provided with a material receiving inlet 141 and a material receiving outlet 142 arranged opposite to each other in the vertical direction, with the material receiving inlet 141 at the top and the material receiving outlet 142 at the bottom. The material receiving member 120 is inserted into the material receiving sleeve 140, and the opening of the material receiving trough 121 is connected to the material receiving inlet 141 when it faces upward, and is connected to the material receiving outlet 142 when it faces downward. At least part of the inner side wall of the material receiving sleeve 140 forms a shielding portion. The material receiving sleeve 140 can shield the opening of the material receiving trough 121 to prevent the material receiving member 120 from rotating too fast and causing the first workpiece 1000 inside to be thrown out. This ensures a high rotation speed of the material receiving member 120 while improving the safety of the rotation process.

[0052] Combine Figure 3 As shown, in some embodiments, the material receiving assembly further includes a rack 131 and a gear 132. The gear 132 is coaxially connected to the material receiving member 120. The rack 131 is slidably disposed on the material receiving bracket 110 and meshes with the gear 132. The material receiving drive member 130 is disposed on the material receiving bracket 110 and is in transmission connection with the rack 131. In some embodiments, the material receiving drive member 130 is a telescopic cylinder. In other embodiments, the material receiving drive member 130 can be a servo motor to directly drive the material receiving member 120 to rotate.

[0053] When transferring the first workpiece 1000 to the transfer hole 221, the first workpiece 1000 can fall into the transfer hole 221 under its own weight. To prevent the first workpiece 1000 from sticking to the receiving trough 121 and preventing it from falling under its own weight, in some embodiments, the receiving member 120 is provided with a blowing channel extending parallel to the axis of the receiving member 120. One end of the blowing channel is connected to the receiving trough 121, and the other end passes through the end of the receiving member 120 and can be connected to an external air source. The blowing channel and the receiving trough 121 are connected at the bottom of the receiving trough 121.

[0054] The first workpiece 1000 can flow out of the discharge port in turn. In order to prevent the first workpiece 1000 located upstream of the material receiving member 120 from affecting the rotation of the material receiving member 120, in some embodiments, the material dividing assembly includes a material dividing bracket 150, a material dividing drive member 160 and a material dividing member 170. The material dividing bracket 150 is provided with a material dividing channel 151, and the outlet at the lower end of the material dividing channel 151 forms the discharge port. The material dividing bracket 150 is provided on the material receiving bracket 110, and the material dividing member 170 is provided on the material dividing bracket 150, and its material dividing end can be extended into the material dividing channel 151 to lock the first workpiece 1000 or be pulled out from the material dividing channel 151 to unlock the first workpiece 1000. The material dividing drive member 160 is provided on the material dividing bracket 150, and its output end is transmission connected to the material dividing member 170.

[0055] Furthermore, the material dividing assembly also includes a material dividing lifting drive member 180, a material dividing bracket 150 is slidably arranged on the material receiving bracket 110 in the vertical direction, and the material dividing lifting drive member 180 is arranged on the material receiving bracket 110, and its output end is transmission-connected with the material dividing bracket 150. The length of the first workpiece 1000 can be less than the depth of the material receiving trough 121, so that the first workpiece 1000 is completely located in the material receiving trough 121, avoiding interference between the first workpiece 1000 and the material receiving sleeve 140 during the rotation of the material receiving member 120; at the same time, before the material receiving member 120 rotates, the material dividing bracket 150 is moved upward, so that the first workpiece 1000 in the material dividing channel 151 is away from the material receiving trough 121, avoiding interference with the material receiving member 120; finally, the material receiving trough 121 can accommodate the first workpiece 1000 while also having some margin, thereby reducing processing difficulty and reducing costs.

[0056] Of course, in other embodiments, the depth of the receiving trough 121 and the length of the first workpiece 1000 can be set to be the same. Under this structure, there is no need to set the material separation and lifting drive component 180, which simplifies the operation process to a certain extent.

[0057] The front and back of the first workpiece 1000 directly affect the assembly yield rate. The detection component 300 includes a test base 310, a test movable part 320, a test driving part 330, a test part 340 and a front and back detection part 350. The test movable part 320 slides in the vertical direction and is arranged on the test base 310. The test driving part 330 is arranged on the test base 310, and its output end is transmission-connected with the test movable part 320. The front and back detection part 350 is arranged on the test movable part 320. The test part 340 slides in the vertical direction and is arranged on the test movable part 320. The lower end of the test part 340 is provided with a conical groove. One end of the first workpiece 1000 has a conical protrusion 1100 that can be inserted into the conical groove. The outer diameter of the other end of the first workpiece 1000 is larger than the opening diameter of the conical groove. During testing, the test driving member 330 drives the test moving member 320 to descend, and drives the test member 340 to descend synchronously. When the conical protrusion 1100 of the first workpiece 1000 is facing downward, the test member 340 abuts against the other end of the first workpiece 1000. Supported by the first workpiece 1000, the test member 340 rises relative to the test moving member 320, and the upper end of the test member 340 enters the testing range of the positive and negative test members 340; when the conical protrusion 1100 of the first workpiece 1000 is facing upward, the conical groove is sleeved outside the conical protrusion 1100, and the test member 340 follows the test moving member 320 to fall normally, and the upper end of the test member 340 moves out of the testing range of the positive and negative test members 340. It should be noted that when the test piece 340 is in the initial position, its upper end is outside the test range of the front and back test pieces 340; in other words, when the test movable piece 320 is descending, the upper end of the test piece 340 is outside the test range of the front and back test pieces 340.

[0058] Exemplarily, the front and back test pieces 340 are photoelectric sensors. When the test piece 340 is in the initial position, its upper end is located under the test light of the photoelectric sensor. When the test piece 340 rises relative to the test movable piece 320, its upper end rises to the irradiation path of the test light of the photoelectric sensor.

[0059] Among them, the test movable part 320 is provided with a test channel, the test part 340 is a rod-shaped part, and has a stop part 341, the test part 340 is passed through the test channel, the stop part 341 is located above the test channel, and the outer diameter of the stop part 341 is larger than the inner diameter of the test channel.

[0060] When it is detected that the first workpiece 1000 is in the wrong orientation, that is, upside down, it is necessary to move the first workpiece 1000 out of the transfer part 220. The detection component 300 also includes a waste part 360 and a waste drive part 370. The waste part 360 is provided with a waste hole 361. The waste part 360 is slidably arranged on the transfer base 210. The waste drive part 370 is arranged on the transfer base 210 and is transmission-connected to the waste part 360 so that when the upper end of the test piece 340 moves out of the test range of the positive and negative test pieces 340, the waste hole 361 is driven to the bottom of the transfer hole 221, and the first workpiece 1000 in the transfer hole 221 falls from the waste hole 361.

[0061] Specifically, the transfer base 210 is provided with a waste avoidance gap, the initial position of the waste piece 360 ​​is located in the waste avoidance gap, and the upper end surface is flush with the upper end surface of the transfer base 210, and can block the transfer hole 221. When the first workpiece 1000 is not in the correct orientation, the waste piece 360 ​​can move toward the axial direction of the transfer piece 220 so that the waste hole 361 is opposite to the transfer hole 221. At this time, the first workpiece 1000 can fall from the waste hole 361 into the waste collection piece below.

[0062] Combine Figure 3 and Figure 4 As shown, the shaft parts assembly device further includes an assembly component 400, which includes a positioning member 410 and a positioning drive member 420. The positioning member 410 is provided with a positioning hole 411. The positioning member 410 is slidably disposed on the transfer base 210 and is located in the blanking avoidance gap. The positioning drive member 420 is disposed on the transfer base 210 and is transmission-connected to the positioning member 410 to drive the positioning member 410 to move to a position for positioning the second workpiece 2000, with the positioning hole 411 located between the transfer hole 221 and the shaft hole 2100. When the positioning member 410 moves to the position for positioning the second workpiece 2000, the second workpiece 2000 can be brought into contact with the side wall of the track. After the second workpiece 2000 is positioned, the positioning accuracy of the second workpiece 2000 is guaranteed. In this state, the positioning hole 411 is connected between the transfer hole 221 and the axial hole 2100. The first workpiece 1000 located in the transfer hole 221 is moved out of the transfer hole 221 under the action of gravity, and enters the axial hole 2100 after passing through the positioning hole 411.

[0063] To ensure that the first workpiece 1000 can be smoothly removed from the transfer hole 221, in some embodiments, Figure 7 As shown, the assembly component 400 includes a crimping base 430, a crimping member 440 and a crimping driving member 450. The crimping member 440 is slidably arranged on the crimping base 430 along the vertical direction. The crimping driving member 450 is arranged on the crimping base 430 and is transmission-connected to the crimping member 440. The crimping driving member 450 can drive the crimping member 440 into the transfer hole 221 to move the first workpiece 1000 into the axial hole 2100.

[0064] After the first workpiece 1000 falls into the axial hole 2100, the transfer member 220 continues to rotate so that the transfer hole 221 rotates to the bottom of the receiving trough 121 to receive the next first workpiece 1000. To ensure that the interior of the axial hole 2100 is empty when receiving the first workpiece 1000, in some embodiments, during the rotation of the transfer member 220, the transfer hole 221 passes through the emptying position. The transfer base 210 is provided with an emptying avoidance notch 211 at the emptying position. The first workpiece 1000 in the transfer hole 221 will fall through the emptying avoidance notch 211 into the emptying collection box 212 below.

[0065] Regarding the automatic supply of the first workpiece 1000, in some embodiments, the first feeding assembly 100 also includes a first vibration disk 190 and a feeding pipe 191. One end of the feeding channel is connected to the outlet of the first vibration disk 190, and the other end is connected to the distribution channel 151. The first vibration disk 190 is used to vibrate the first workpiece 1000 so that it moves to the feeding pipe 191 in an orderly manner. The first workpiece 1000 can slide along the feeding pipe 191 to the distribution channel 151 provided on the distribution bracket 150.

[0066] In some embodiments, the transfer member 220 may be provided with a plurality of transfer holes 221 to enable the synchronous transfer of a plurality of first workpieces 1000, thereby improving the assembly efficiency of the first workpieces 1000 and the second workpieces 2000. The plurality of second workpieces 2000 are transported at intervals, and the plurality of first workpieces 1000 are sequentially arranged in the plurality of transfer holes 221 in the arrangement direction of the second workpieces 2000. For example, the transfer member 220 may be provided with eight transfer holes 221, divided into four groups, each group including two transfer holes 221. In this embodiment, when the transfer member 220 is rotated to the assembly position, the positioning member 410 is in the initial position, which can block the bottoms of the two transfer holes 221 in the same group of the assembly position, so that the two first workpieces 1000 are both maintained above the positioning member 410. After the first workpiece 1000 and the second workpiece 2000 are moved to the assembly position, the positioning member 410 moves along the axis away from the transfer member 220 to the position for positioning the second workpiece 2000, and the two first workpieces 1000 fall into the corresponding two axial holes 2100. In some embodiments, the first workpiece 1000 and the second workpiece 2000 can be moved to the assembly position sequentially or simultaneously.

[0067] In other embodiments, each group of transfer members 220 may be provided with three or more transfer holes 221 .

[0068] In order to improve assembly efficiency, the shaft parts assembly device also includes an assembly line 500 and a second feeding assembly 600. The assembly line 500 is used to transport a carrier carrying a second workpiece 2000 and can deliver the carrier to the assembly position. The second feeding assembly 600 is used to supply the second workpiece 2000 to the carrier located at the receiving position of the assembly line 500. The assembly line 500 includes a bracket and a plurality of sliding and spaced-apart toggles arranged on the bracket. The toggles move back and forth along the transmission direction of the assembly line 500 to toggle the carrier on the assembly line 500. Among them, when the toggles move forward, they can drive the carrier forward. When the toggles move backward, they flip forward and then move backward alone. When they move forward again, they flip backward under the action of the elastic member and drive the carrier forward again. At least a portion of the bracket forms a track. This embodiment does not specifically limit the specific structure of the toggles.

[0069] In some embodiments, it is necessary to assemble a third workpiece into the shaft hole 2100 before the first workpiece 1000 is assembled into the shaft hole 2100. For this purpose, the shaft parts assembly device also includes a third feeding assembly 700, which is used to supply the third workpiece into the shaft hole 2100 of the first workpiece 1000 located at the delivery position. The delivery position is located between the material receiving position and the assembly position. Since the third workpiece only needs to be placed in the shaft hole 2100, there is no need to detect the front and back, and no large impact will be generated. It can be directly transported to the shaft hole 2100 at the delivery position through a conveying pipeline. In some embodiments, the third workpiece is a spring. The specific spring supply structure can be set according to the above-mentioned feed pipe 191. In other embodiments, the specific spring supply structure and supply method can be set with reference to the existing technology and are not limited here.
