For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0043] Embodiments of the present invention are described in detail below, examples of which 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 only used to explain the present invention, and cannot be understood as limiting the present invention.

[0044] like Figures 1 to 7As shown, the present embodiment provides a shaft parts assembly device, which is used to assemble a first workpiece 1000 of a shaft-like structure into an axial hole 2100 of a second workpiece 2000 at an assembly position, and improve 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 dividing component and a material receiving component. The material dividing component has a material outlet 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 driving member 130. The material receiving member 120 is provided with a material receiving trough 121. The material receiving member 120 is rotatably disposed on the material receiving bracket 110. The material receiving driving 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 dropped from the material outlet, or opens The mouth faces downward to move the first workpiece 1000 in the receiving trough 121 out; the transfer component 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 component 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 buffer the impact generated when the first workpiece 1000 falls, avoid 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 receiving piece 120 rotates to the opening of the receiving groove 121 facing downward, the first workpiece 1000 is transferred to the transfer hole 221 of the transfer piece 220 and contacts the transfer base 210. When the transfer piece 220 rotates to the detection position, the front and back of the first workpiece 1000 can be detected by the detection component 300. When the transfer piece 220 rotates to the assembly position, the first workpiece 1000 falls into the axial hole 2100 of the second workpiece 2000 through the drop avoidance gap.

[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 part of the first workpiece 1000 in the transfer hole 221 is inserted into the pit, causing the transfer part 220 to be locked and 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 due to 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 at a position other than upward and downward.

[0051] Combination 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 which are arranged opposite to each other in the vertical direction, the material receiving inlet 141 is at the top, and the material receiving outlet 142 is at the bottom, the material receiving member 120 is penetrated through the material receiving sleeve 140, and the opening of the material receiving groove 121 is connected with the material receiving inlet 141 when it faces upward, and is connected with the material receiving outlet 142 when it faces downward, and 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 groove 121 to avoid the problem that the first workpiece 1000 inside is thrown out due to the excessively fast rotation speed of the material receiving member 120, while ensuring a high rotation speed of the material receiving member 120 and improving the safety of the rotation process.

[0052] Combination Figure 3 As shown, in some embodiments, the material receiving assembly further includes a rack 131 and a gear 132, the gear 132 and the material receiving member 120 are coaxially connected, the rack 131 is slidably disposed on the material receiving bracket 110 and meshes with the gear 132, and the material receiving drive member 130 is disposed on the material receiving bracket 110 and is transmission-connected 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 the first workpiece 1000 is transferred to the transfer hole 221, the first workpiece 1000 can fall into the transfer hole 221 by its own weight. In order to prevent the first workpiece 1000 from being stuck to the receiving trough 121 and being unable to fall under its own weight, in some embodiments, the receiving member 120 is provided with a blowing channel extending in a direction 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 sequence. In order to prevent the first workpiece 1000 located upstream of the material receiving piece 120 from affecting the rotation of the material receiving piece 120, in some embodiments, the material dividing assembly includes a material dividing bracket 150, a material dividing drive 160 and a material dividing piece 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 arranged on the material receiving bracket 110, and the material dividing piece 170 is arranged on the material dividing bracket 150, and its material dividing end can extend 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 160 is arranged on the material dividing bracket 150, and its output end is transmission connected with the material dividing piece 170.

[0055] Furthermore, the material dividing assembly also includes a material dividing lifting driving member 180, and the material dividing bracket 150 is slidably arranged on the material receiving bracket 110 in the vertical direction. The material dividing lifting driving 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 groove 121, so that the first workpiece 1000 is completely located in the material receiving groove 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 up, so that the first workpiece 1000 in the material dividing channel 151 is away from the material receiving groove 121, avoiding interference with the material receiving member 120; finally, the material receiving groove 121 can accommodate the first workpiece 1000 while also having a partial margin, thereby reducing the processing difficulty and cost.

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

[0057] The front and back of the first workpiece 1000 directly affect the yield of assembly. The detection component 300 includes a test base 310, a test movable part 320, a test drive part 330, a test piece 340 and a front and back detection piece 350. The test movable part 320 is slidably arranged on the test base 310 along the vertical direction. The test drive 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 piece 350 is arranged on the test movable part 320. The test piece 340 is slidably arranged on the test movable part 320 along the vertical direction. A conical groove is provided at the lower end of the test piece 340. 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 downward, the test member 340 abuts against the other end of the first workpiece 1000, and the test member 340 rises relative to the test moving member 320 under the support of the first workpiece 1000, 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 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 positive and negative 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 positive and negative 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 member 320 is provided with a test channel, the test member 340 is a rod-shaped member and has a stopper 341, the test member 340 is inserted into the test channel, the stopper 341 is located above the test channel, and the outer diameter of the stopper 341 is greater 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 piece 220. The detection component 300 also includes a waste piece 360 ​​and a waste drive piece 370. The waste piece 360 ​​is provided with a waste hole 361. The waste piece 360 ​​is slidably arranged on the transfer base 210. The waste drive piece 370 is arranged on the transfer base 210 and is transmission-connected to the waste piece 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 be directly below 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 in the wrong 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] Combination Figure 3 and Figure 4 As shown, the shaft parts assembly device also 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 with the positioning member 410 to drive the positioning member 410 to move to the position for positioning the second workpiece 2000, and the positioning hole 411 is 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 abutted against the side wall of the track. After the second workpiece 2000 is positioned, the position accuracy of the second workpiece 2000 is guaranteed. In this state, the positioning hole 411 is connected between the transit hole 221 and the axial hole 2100. The first workpiece 1000 located in the transit hole 221 is moved out of the transit 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 shaft 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 shaft hole 2100 is emptied 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, and the transfer base 210 is provided with an emptying avoidance notch 211 at the emptying position, and the first workpiece 1000 in the transfer hole 221 will fall from the emptying avoidance notch 211 to 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 plate 190 and a feeding pipe 191, one end of the feeding channel is connected to the outlet of the first vibration plate 190, and the other end is connected to the distribution channel 151, the first vibration plate 190 is used to vibrate the first workpiece 1000 so that it moves to the feeding pipe 191 in an orderly manner, and the first workpiece 1000 can slide along the feeding pipe 191 to the distribution channel 151 provided on the distribution bracket 150.
