Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. If the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.
[0040] Depend on Figure 1 , Figure 2 and Figure 9 As shown in the figure, this embodiment of the invention discloses a pin insertion rotary table device 1, including a rotary table 11 for driving a positioning fixture 111 to rotate between various workstations, a part vibration feeding mechanism 12 for providing parts to be assembled, a suction and transport mechanism 13 for adsorbing and transporting the parts to be assembled onto the positioning fixture 111 in place, a mounting shaft vibration feeding mechanism 14 for simultaneously providing multiple mounting shafts 1022, and a pin insertion mechanism 15 for simultaneously inserting multiple mounting shafts 1022 into the parts to be assembled to form an assembly module. This embodiment uses a deceleration frame 1021 as the part to be assembled and a deceleration frame module 102 as the assembly module to describe the above mechanisms in detail.
[0041] In one specific embodiment, the part vibration feeding mechanism 12 includes a vibratory plate, a linear vibrator 121, and a part positioning structure 122; the outlet of the linear vibrator 121 corresponds to the inlet of the vibratory plate, and the part positioning structure 122 includes a support platform and a positioning groove disposed on the support platform, the positioning groove corresponding to the outlet of the vibratory plate; the adsorption and conveying mechanism 13 is used to adsorb and convey the parts to be assembled (reduction frame 1021) conveyed to the positioning groove to the positioning fixture 111.
[0042] In another specific embodiment, by Figure 3As shown, the adsorption and conveying mechanism 13 includes a support, a horizontal drive module 131 (which can be a horizontal cylinder, electric cylinder, or other linear motion component) mounted on the support, a vertical drive component 132 (which can be a vertical cylinder, electric cylinder, or other linear motion component) mounted on the drive end of the horizontal drive module 131, and a floating suction nozzle structure 133 mounted on the drive end of the vertical drive component 132. The floating suction nozzle structure 133 includes a mounting base, a suction nozzle rod vertically slidably mounted on the mounting base, a suction nozzle mounted at the bottom end of the suction nozzle rod, and a spring sleeved on the suction nozzle rod. One end of the spring abuts against the mounting base, and the other end abuts against the suction nozzle. The top end of the suction nozzle rod has a vent connector communicating with its inner cavity. This configuration allows for the adsorption of parts to be assembled while preventing damage to the parts due to hard impacts.
[0043] The mounting shaft vibration feeding mechanism 14 includes a vibratory plate, and a positioning block is provided at the discharge port of the vibratory plate. The positioning block is provided with at least one spring tube (or flexible tube) for guiding the mounting shaft 1022 during feeding.
[0044] In another specific embodiment, by Figure 4 and Figure 5 As shown, the pin insertion mechanism 15 includes a mounting platform 151 located above the rotary table 11. The mounting platform 151 is equipped with a support frame 152, a horizontal transfer structure 153, and a mounting shaft positioning block 154. The top of the support frame 152 is provided with a pin pressing structure 155, and the side is provided with a guide structure 156 (a guide block with multiple guide channels). The horizontal transfer structure 153 includes a transfer plate 1531 and a horizontal drive component 1532 (linear motor, electric cylinder, electric push rod, etc.) for driving the transfer plate 1531 to move below the pin pressing structure 155. The side of the support frame 152 is provided with a clearance opening to avoid the transfer plate 1531. The transfer plate 1531 is slidably mounted on the mounting platform 151 via a guide rail (e.g., ...). This ensures the stability and reliability of the movement of the transfer plate 1531. The transfer plate 1531 is located below the guide structure 156 and above the mounting shaft positioning block 154. The transfer plate 1531 has multiple mounting shaft receiving holes, and the mounting shaft positioning block 154 has multiple guide positioning through holes. The guide structure 156 uses multiple spring tubes to vertically guide all the mounting shafts 1022 supplied by the mounting shaft vibration feeding mechanism 14 into the corresponding mounting shaft receiving holes. The transfer plate 1531 carries the mounting shafts 1022 to the bottom of the ejector pin pressing structure 155. The ejector pin pressing structure 155 simultaneously pushes all the mounting shafts 1022 in the gear shaft receiving holes. The mounting shafts 1022 are inserted into the reduction gear 1021 through the corresponding guide positioning through holes. This configuration allows for the simultaneous insertion of multiple mounting shafts 1022. Furthermore, during the insertion process, the mounting shaft receiving hole and the guide positioning through hole guide the mounting shaft 1022, effectively preventing bending of the mounting shaft 1022 and ensuring insertion accuracy.
[0045] Preferably, two vibratory feeding mechanisms 14 for mounting shafts 1022 of different lengths are arranged side by side; a guide structure 156 (guide block) is provided on each of the opposite sides of the support frame 152, and the two guide structures 156 correspond one-to-one with the two vibratory feeding mechanisms 14 for guiding mounting shafts 1022 of different lengths. Two horizontal transfer structures 153 are provided and located on opposite sides of the support frame 152; the mounting shaft positioning block 154 is stepped and includes a first positioning part and a second positioning part; one transfer plate 1531 is located above the first positioning part, and the other transfer plate 1531 is located above the second positioning part. With this arrangement, the mounting shaft positioning block 154 is stepped, the two horizontal transfer structures 153 operate in both directions, and the two transfer plates 1531 can transfer mounting shafts 1022 of different lengths respectively, realizing the synchronous insertion of different types of mounting shafts 1022 and further improving production efficiency.
[0046] Below the rotary table 11 corresponding to the pin insertion mechanism 15, there is a lifting mechanism 16 for lifting the part to be assembled (reduction gear 1021) on the positioning fixture 111 to assist in the insertion of the mounting shaft 1022. (It has an adsorption channel for adsorbing and fixing the reduction gear 1021 to prevent the reduction gear 1021 from moving during the lifting process.) The pin pressing structure 155 includes a pressing drive 1551 and a mounting block 1552 connected to the power unit of the pressing drive 1551 and vertically slidably mounted on the support frame 152. The bottom of the mounting block 1552 is provided with a pin 1553 and a floating push rod assembly 1554. The floating push rod assembly 1554 includes an elastic element 15541 and a push rod 15542. The elastic element 15541 is used to provide an elastic force that makes the push rod 15542 tend to move towards the part to be assembled (reduction gear 1021). When the mounting shaft 1022 is inserted, the lifting mechanism 16 first lifts the deceleration frame 1021 from the positioning fixture 111, so that it enters the clearance opening at the bottom of the mounting platform 151 and abuts against the bottom surface of the mounting shaft positioning block 154 (the mounting holes on the deceleration frame 1021 correspond one-to-one with the guide positioning through holes); then the pressing drive 1551 in the ejector pin pressing structure 155 is activated, and the ejector pin 1553 pushes the mounting shaft 1022 in the mounting shaft receiving hole onto the deceleration frame 1021, completing the assembly of the deceleration frame module 102. During insertion, the ejector pin 15542 in the floating ejector pin assembly 1554 abuts against the deceleration frame 1021 (the elastic element 15541 is compressed). After the insertion is completed, when the lifting mechanism 16 drives the deceleration frame module 102 to descend, the floating ejector pin assembly 1554 still gives the deceleration frame 1021 a downward force, which facilitates the separation of the deceleration frame 1021 from the mounting shaft positioning block 154 and prevents material from being carried along.
[0047] In another specific embodiment, by Figure 6As shown, the pin rotation stage device 1 also includes an insertion positioning detection mechanism 17 (height detection principle) for detecting whether the mounting shaft 1022 is inserted in place; the insertion positioning detection mechanism 17 includes a bracket 171, a vertical moving member 172 disposed on the bracket 171, a connecting frame 173 disposed on the moving end of the vertical moving member 172, a plurality of floating trigger structures 174 vertically slidably mounted on the connecting frame 173, and a plurality of photoelectric sensors 175 disposed on the connecting frame 173 and adapted one-to-one with the floating trigger structures 174; the number of floating trigger structures 174 corresponds to the number of mounting shafts 1022.
[0048] In another specific embodiment, the pin insertion rotary table device 1 further includes a first product handling mechanism 18 and a linear vibrating feeder 19 for buffering and conveying the deceleration frame module 102. Along the rotation direction of the rotary table 11, the first product handling mechanism 18 is located downstream of the insertion positioning detection mechanism 17. The first product handling mechanism 18 is used to absorb and transport the qualified assembly module (deceleration frame module 102) from the positioning fixture 111 onto the linear vibrating feeder 19. In addition, the pin insertion rotary table device 1 also includes a waste recycling device for storing unqualified deceleration frame modules 102 and a qualified product collection device. When the pin insertion rotary table device 1 is used as a standalone device, the first product handling mechanism 18 can absorb and transport qualified deceleration frame modules 102 into the qualified product collection device. With this configuration, the pin insertion rotary table device 1 can function as a standalone device for pin insertion operations, or it can be integrated with other devices to complete the assembly after pin insertion, thus improving its versatility.
[0049] More preferably, the pin insertion rotary table device 1 further includes a void detection mechanism 110; along the rotation direction of the rotary table 11, the void detection mechanism 110 is located downstream of the first product handling mechanism 18, and is used to detect whether the assembly module (deceleration frame module 102) on the positioning fixture 111 has been removed, so as to prevent stacking during the next material feeding. The structure and principle of the void detection mechanism 110 are similar to those of the insertion position detection mechanism 17, and will not be described in detail here.
[0050] The working process of the pin rotary table device 1 is briefly described below based on its structure:
[0051] The rotary table 11 drives the positioning fixture 111 to rotate (counterclockwise). When it reaches the deceleration frame loading station, the adsorption and conveying mechanism 13 adsorbs and conveys the deceleration frame 1021, which is already positioned on the part positioning structure 122 in the part vibration loading mechanism 12, onto the positioning fixture 111. When the positioning fixture 111 carrying the deceleration frame 1021 continues to move to the pin insertion station, the lifting mechanism 16 lifts the deceleration frame 1021 in the positioning fixture 111 until it abuts against the bottom surface of the mounting shaft positioning block 154; the pin insertion mechanism 15 operates to simultaneously insert multiple mounting shafts 1022 supplied by the mounting shaft vibration loading mechanism 14 into the deceleration frame 1021 to form the deceleration frame module 102. When the positioning fixture 111 carrying the deceleration frame module 102 continues to flow to the insertion and inspection station, the insertion and inspection mechanism 17 checks whether the installation shaft 1022 is installed correctly; the first product handling mechanism 18 adsorbs and transports the qualified deceleration frame module 102 to the linear vibrating feeder 19, and the unqualified deceleration frame module 102 is transported by the first product handling mechanism 18 to the waste recycling device; the void detection mechanism 110 located downstream of the first product handling mechanism 18 performs void detection on the positioning fixture 111.
[0052] Currently, the assembly precision of the speed reducer module 102 in the rotary drive assembly 101 is low. The hooks 10211 on the speed reducer module 102 and the slots 1011 in the rotary drive assembly 101 sometimes fail to engage properly, affecting the stability and reliability of the assembled speed reducer module 102 and rotary drive assembly 101. Therefore, this invention also discloses a product assembly device, including the pin insertion rotary table device 1 and the material handling assembly and detection device 2 disclosed in any of the above embodiments. The material handling assembly and inspection device 2 includes a conveying mechanism 21 for driving the transfer tooling 22 to move, a second product handling mechanism 24 for transporting and assembling the assembly module (reduction frame module 102) onto the semi-finished product (rotary drive assembly 101) carried by the transfer tooling 22, a locking mechanism 25 for radially pushing the hooks 10211 on the assembly module to engage with the slots 1011 on the semi-finished product, and a locking detection mechanism 26 for detecting whether the hooks 10211 are properly engaged in the slots 1011. Compared with the prior art, the material handling assembly and inspection device 2 can improve the assembly accuracy of the rotary drive assembly 101 and the reduction frame module 102 and the stability and reliability after assembly.
[0053] The conveying mechanism 21 includes a belt conveyor and multiple tooling positioning mechanisms 23 located below the conveyor belt in the belt conveyor and corresponding to each workstation. The tooling positioning mechanism 23 is used to stop the flow of the flow tooling 22 in place so that the products on it can be assembled.
[0054] The second product handling mechanism 24 is similar in structure and working principle to the first product handling mechanism 18, and will not be described in detail here.
[0055] Depend on Figure 7 As shown, the locking mechanism 25 includes a first bracket 251, a first lifting drive 252 disposed on the first bracket 251, and a first multi-jaw chuck 253 disposed on the drive part of the first lifting drive 252. The jaws of the first multi-jaw chuck 253 are provided with a first mounting frame 254. A push assembly 255 (including a push rod and a sleeve on the push rod, one end of which abuts against the first mounting frame 254 and the other end of which abuts against the stepped surface of the push rod) is radially slidably mounted on the first mounting frame 254.
[0056] Depend on Figure 8 As shown, the engagement detection mechanism 26 includes a second bracket, a second lifting drive component mounted on the second bracket, and a second multi-jaw chuck 261 mounted on the drive unit of the second lifting drive component. The jaws of the second multi-jaw chuck 261 are provided with a second mounting bracket 262, and the second mounting bracket 262 is provided with a photoelectric detection component 263. The photoelectric detection component 263 includes a floating trigger rod that is radially slidably mounted on the second mounting bracket 262 and a photoelectric sensor adapted to the floating trigger rod.
[0057] The following is a brief description of the working process of the material handling, assembly, and testing device 2, based on its structure:
[0058] The second product handling mechanism 24 in the material handling assembly and testing device 2 transports the deceleration frame module 102, which is conveyed by the linear vibrating feeder 19, to the transfer mechanism 21 and onto the transfer fixture 22, which carries the semi-finished product (rotary drive unit 101). When the transfer fixture 22 continues to transfer to the locking station, the first lifting drive component 252 in the locking mechanism 25 descends to its position, and the jaws of the first multi-jaw chuck 253 move radially toward the hook 10211. The pushing component 255 radially pushes the hook 10211 so that it engages with the rotary drive unit. When the slot 1011 of the assembly 101 engages, the deceleration frame module 102 and the rotary drive assembly 101 form product 100. After engagement, when the transfer fixture 22 carrying product 100 continues to transfer to the engagement detection station, the second lifting drive component in the engagement detection mechanism 26 descends into place, the jaws on the second multi-jaw chuck 261 move radially, and the photoelectric detection component 263 detects whether the hook 10211 is engaged in place. If the engagement is not in place, manual adjustment is made. If the engagement is in place, the transfer fixture 22 continues to transfer to the next station.
[0059] The various embodiments in this specification are described in a progressive or parallel manner. Each embodiment focuses on the differences from other embodiments, and the same or similar parts between the various embodiments can be referred to each other.
[0060] In summary, compared with the prior art, the present invention can simultaneously insert multiple mounting shafts onto the parts to be assembled, which not only improves tooling efficiency but also ensures the consistency of insertion, avoids damage to the mounting shafts, and improves the product qualification rate; it meets actual production needs; in addition, it can improve the assembly accuracy of semi-finished products and assembly modules and the stability and reliability after assembly.

Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
