Description

Technical Field

[0001] The present invention relates to the field of low-voltage electrical appliances, and particularly to a fixing bracket feeding device and a wall switch assembly equipment. Background Art

[0002] In existing series products such as wall switches and sockets, the fixing bracket and the mounting bracket need to be assembled together. However, the structure of the fixing bracket is complex and irregular. During production and blanking, manual work is often required to place and pack the products after equipment blanking, revealing problems such as low automation degree at the back end.

[0003] In addition, after the mounting bracket is integrally injection molded, it usually needs to be placed and packed before being used for assembly with the fixing bracket, increasing the manual placement and packing process and resulting in low efficiency. Summary of the Invention

[0004] The purpose of the present invention is to overcome at least one defect of the prior art and provide a wall switch assembly equipment.

[0005] To achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A fixing bracket feeding device includes a material distribution device and a feeding tooling. The material distribution device is arranged below the feeding tooling. The feeding tooling includes a guide rail structure for passing through the mounting holes of the fixing brackets, enabling a plurality of fixing brackets to be sleeved on the guide rail structure and slide along the guide rail structure towards the material distribution device. The material distribution device includes at least two groups of limiting mechanisms. Two of the limiting mechanisms are used to limit two adjacent fixing brackets. When one group of the limiting mechanisms releases a fixing bracket, the other group of the limiting mechanisms is used to block the fixing brackets behind.

[0007] Preferably, the material distribution device includes a material distribution seat with a material distribution cavity provided therein. The guide rail structure is inserted into the material distribution cavity so that the fixing brackets can slide into the material distribution cavity. The limiting mechanism includes a limiting block that can move into the material distribution cavity.

[0008] Preferably, the feeding tooling is detachably connected to the material distribution device. A support structure is provided above the material distribution seat for supporting and fixing the guide rail structure.

[0009] Preferably, the two ends of the guide rail structure are respectively provided with a material distribution end and a limiting end. The limiting end is provided with a blocking structure. When the limiting end is located below the material distribution end, the blocking structure is used to block the movement of the fixing brackets, enabling a plurality of fixing brackets to be sleeved on the guide rail structure and stacked above the blocking structure. When the feeding tooling is buckled above the material distribution device and the material distribution end is located below the limiting end, the plurality of fixing brackets move towards the material distribution end respectively.

[0010] Preferably, the loading tooling is detachably connected to the material distribution device. A support structure is provided above the material distribution seat. A positioning pin is provided on the support structure, and a positioning hole is provided on the blocking structure. The material distribution end of the guide rail structure is inserted into the material distribution cavity, and the positioning hole is sleeved on the positioning pin to achieve detachable connection.

[0011] Preferably, the loading tooling includes four of the guide rail structures and a quadrilateral support plate arranged between the four guide rail structures. The four guide rail structures respectively include two first guide plates arranged vertically and a second guide plate connected between the two first guide plates of each. The second guide plates of the four guide rail structures are respectively in a curved surface shape, and the inner sides respectively cooperate with the four top corners of the support plate. The inner sides of the first guide plates of the four guide rail structures respectively cooperate with the four side edges of the support plate. The outer sides of the first guide plates and the second guide plates are respectively used for sliding cooperation with the rounded corners of the inner ring of the fixing frame.

[0012] Preferably, the support plate is detachably connected to the guide rail structure and the blocking structure respectively.

[0013] Preferably, the support structure includes a support frame with a U-shaped cross-section. The guide rail structure is installed inside the U-shaped structure, and a positioning pin is provided at the top of the support frame.

[0014] Preferably, the support frame includes two L-shaped baffles and a plurality of brackets respectively connected to the two baffles. The two baffles respectively include a first baffle edge and a second baffle edge connected to each other. The second baffle edges of the two baffles are arranged at intervals and flush. The first baffle edges of the two baffles are arranged opposite to each other. The two baffles enclose a loading space in a U-shaped structure. The guide rail structure can be inserted into the inner side of the loading space. The bracket is in a U-shaped structure and includes two first support rods arranged opposite to each other and a second support rod connected between the two first support rods. The first support rods are respectively connected to the first baffle edges of the two baffles, and the second support rods are respectively connected to the second baffle edges of the two baffles. The plurality of brackets are arranged along the length direction of the baffle. The distance between the two first support rods is less than the width of the blocking structure, and positioning pins are respectively provided on the two first support rods of the topmost bracket.

[0015] Preferably, the distance between the two first support rods of the bracket is greater than the distance between the first baffle edges of the two baffles, and one of the baffles is detachably connected to the bracket.

[0016] Preferably, the material distribution device includes upper and lower sets of limiting mechanisms. The two sets of limiting mechanisms are respectively a material distribution limiting mechanism and a blanking limiting mechanism. The blanking limiting mechanism is arranged below the material distribution limiting mechanism. Each of the two sets of limiting mechanisms includes two relatively arranged limiting blocks, and a material distribution cylinder for driving the two limiting blocks of each set to clamp and separate respectively. When both the material distribution limiting mechanism and the blanking limiting mechanism are clamped, the two lowermost fixing frames of the feeding tooling can be limited. When only the blanking limiting mechanism is opened, the blocked fixing frame can be released. When the blanking limiting mechanism clamps again and only the material distribution limiting mechanism is opened, the rear fixing frame can be released to the position blocked by the blanking limiting mechanism.

[0017] In the fixing frame feeding device of the present invention, the guide rail structure guides the fixing frame. Since the rounded corner is located in the inner ring of the fixing frame and the thickness of the rounded corner is greater than that of the outer ring fixing frame, the fixing frames cannot be stacked naturally, making it difficult to carry out automated design. However, by passing the guide rail structure through the fixing frame and slidingly mating with the rounded corner, not only can it cooperate with the material distribution device to achieve automated material distribution and realize the replenishment function without stopping the machine, but also it can meet the requirements of high efficiency, low manufacturing cost, and stable operation of the equipment. Moreover, the sliding fit between the guide rail structure and the rounded corner in the inner ring of the fixing frame is more stable, and there will be no jamming problem caused by inclination when mating with the outer ring of the fixing frame.

[0018] A wall switch assembly equipment includes a first feeding device, a second feeding device, and an assembly device. The first feeding device and the second feeding device are respectively used to sequentially send the fixing frame of the wall switch and the mounting frame of the wall switch to the assembly device. The assembly device is used to assemble the fixing frame and the mounting frame into an integrated assembly. The first feeding device is the above-mentioned fixing frame feeding device.

[0019] Preferably, the assembly device includes a moving device and a pressing device. The moving device sequentially passes through the first feeding device, the second feeding device, and the pressing device, and is used to obtain the distributed fixing frame from the first feeding device, obtain the mounting frame from the second feeding device, and align the mounting holes on the fixing frame with the mounting frame. The pressing device is used to press the mounting frame into the mounting hole to form an integrated assembly of the fixing frame and the mounting frame.

[0020] Preferably, the moving device further includes a lifting device for cooperating with the second feeding device. The second feeding device is a feeding manipulator. The lifting device is used to drive the fixing frame to rise. The feeding manipulator is used to directly take out the formed mounting frame in the injection molding machine and align it with the fixing frame in the lifting device.

[0021] Preferably, the pressing device includes a pressing plate and a downward pressing cylinder for driving the pressing plate to move.

[0022] Preferably, a suction cup device is provided on the pressing plate for sucking away the assembled assembly.

[0023] Preferably, the lifting device includes clamping members arranged oppositely, and a jaw cylinder for driving the two clamping members to clamp and release. The jaw cylinder is connected to a lifting cylinder, and the lifting cylinder is used to drive the jaw cylinder to move up and down.

[0024] Preferably, the moving device includes a transverse moving device and a lifting device. The transverse moving device includes a first carrier, a second carrier, a third carrier and a transverse moving cylinder that are linked. The piston rod of the transverse moving cylinder can reciprocate between a first position and a second position, and drives the first carrier, the second carrier and the third carrier to move respectively when moving. The first carrier, the second carrier and the third carrier are respectively slidably arranged on a track. A positioning plate is provided on the first carrier, and the positioning plate cooperates with a first positioning block and a second positioning block respectively. When the transverse moving cylinder moves to the first position and the second position respectively, the positioning plate contacts and limits the first positioning block and the second positioning block respectively. A first working station, a second working station, a third working station and a fourth working station are sequentially arranged in the moving direction of the first carrier, the second carrier and the third carrier. When the transverse moving cylinder moves to the first position, the first carrier, the second carrier and the third carrier are respectively located at the first working station, the second working station and the third working station. When the transverse moving cylinder moves to the second position, the first carrier, the second carrier and the third carrier are respectively located at the second working station, the third working station and the fourth working station. The first feeding device, the lifting device and the pressing device are respectively arranged above the first working station, the second working station and the third working station. A blanking device is provided above the fourth working station; the fixing frames in the first feeding device sequentially fall into the first carrier, and the first carrier is used to send the fixing frames to the second working station. The lifting device at the second working station is used to take away the fixing frames in the first carrier. The second feeding device is used to align the mounting frames with the mounting holes on the fixing frames and place the mounting frames on the mounting holes. The lifting device then places the mounting frames and the fixing frames on the second carrier, and the second carrier is used to send the mounting frames and the fixing frames to the third working station. The pressing device at the third working station is used to press the mounting frames into the mounting holes to form an assembled component in which the mounting frames and the fixing frames are integrated, and send the assembled component to the third carrier. The third carrier is used to send the assembled component to the fourth working station. The blanking device at the fourth working station is used to take away the assembled component on the third carrier.

[0025] The wall switch assembly equipment of the present invention uses a fixing frame feeding device as the first feeding device to automatically feed the fixing frames, automatically feeds the mounting frames through the second feeding device, and forms an assembled component in which the fixing frames and the mounting frames are integrated through the pressing device, realizing the automatic assembly of the mounting frames and the fixing frames and improving the assembly efficiency.

[0026] In addition, the second feeding device is directly connected to the assembly process equipment after the injection molded parts are discharged from the injection molding machine. It can complete the blanking of the mounting frame and its assembly with the fixing frame before the materials are packed into boxes, achieving economic benefits such as optimizing the subsequent product assembly process, reducing waste in material turnover, and saving labor costs. It can also achieve unmanned participation in assembly and blanking, reduce the intensity of manual operation, and maximize the utilization of site space.

[0027] In addition, by repeatedly moving the transverse cylinder between the first position and the second position, the first carrier, the second carrier, and the third carrier move between the mechanisms respectively, and cooperate with the action beats of each mechanism to realize the synchronous progress of the actions of each working station. This not only greatly shortens the blanking beat of the overall equipment, has the characteristics of high efficiency, but also has a simple and stable process, small occupied space, and low overall manufacturing cost.

Detailed implementation manners

[0040] The following embodiments given in conjunction with the accompanying drawings further illustrate the detailed implementation manners of the wall switch assembly equipment of the present invention. The wall switch assembly equipment of the present invention is not limited to the descriptions of the following embodiments.

[0041] As Figures 1-4 shown, the wall switch assembly equipment of this embodiment includes a first loading device, a second loading device and an assembly device. The first loading device and the second loading device are respectively used to sequentially send the fixing bracket 11 of the wall switch and the mounting bracket 12 of the wall switch to the assembly device, and the assembly device is used to assemble the fixing bracket 11 and the mounting bracket 12 into an integrated assembly.

[0042] The mounting bracket 12 is a plastic part formed by an injection molding machine. The second loading device of this embodiment is a loading manipulator (not shown in the figure), and the loading manipulator is used to directly take out the formed mounting bracket 12 in the injection molding machine and send it to the assembly device;

[0043] The fixing bracket 11 is usually a metal part, and of course it can also be made of other materials. A mounting hole 13 for mounting the mounting bracket 12 is provided in the middle of the fixing bracket 11. Fillets 14 protruding towards the side of the fixing bracket 11 are provided on the hole walls around the mounting hole 13, and the thickness of the fillets 14 is greater than the thickness of the fixing bracket 11.

[0044] The first loading device of this embodiment includes a material distribution device 2 and a loading tooling 3. The material distribution device 2 is arranged below the loading tooling 3. The loading tooling 3 includes a guide rail structure 31 and a blocking structure 32. The guide rail structure 31 is used to pass through the mounting hole 13 of the fixing frame 11 and slidably cooperate with the fillet 14 around the mounting hole 13, so that a plurality of fixing frames 11 can be respectively sleeved on the guide rail structure 31 and slide along the guide rail structure 31 towards the material distribution device 2.

[0045] The material distribution device 2 includes at least two groups of limiting mechanisms. Two of the limiting mechanisms are used to limit two adjacent fixing frames 11. When one group of limiting mechanisms releases a fixing frame 11, the other group of limiting mechanisms is used to block the subsequent fixing frames 11, so that the fixing frames 11 enter the assembly device in sequence.

[0046] The assembly device includes a moving device and a pressing device 4. The moving device passes through the first loading device, the second loading device and the pressing device 4 in sequence, and is used to obtain the distributed fixing frames 11 from the first loading device and obtain the mounting frames 12 from the second loading device, so that the mounting holes 13 on the fixing frames 11 are aligned with the mounting frames 12. The pressing device 4 is used to press the mounting frames 12 into the mounting holes 13 to form a combined component in which the fixing frames 11 and the mounting frames 12 are integrated.

[0047] One improvement point of this embodiment is to provide a fixing frame loading device, that is, the first loading device in the embodiment. The guide rail structure 31 is used to guide the fixing frame 11. Since the fillet 14 is located in the inner circle of the fixing frame 11 and the thickness of the fillet 14 is greater than the thickness of the outer fixing frame 11, the fixing frames 11 cannot be stacked naturally, making it difficult to carry out automated design. By passing the guide rail structure 31 through the fixing frame 11 and slidably cooperating with the fillet 14, it can not only cooperate with the material distribution device 2 to achieve automated material distribution and realize the replenishment function without stopping the machine, but also meet the requirements of high efficiency, low manufacturing cost and stable operation of the equipment. Moreover, the sliding cooperation between the guide rail structure 31 and the fillet 14 in the inner circle of the fixing frame 11 is more stable, and there will be no jamming problem caused by inclination when cooperating with the outer circle of the fixing frame 11.

[0048] Another improvement point of this embodiment is to provide a wall switch assembly device. The fixing frame loading device is used as the first loading device to automatically load the fixing frames 11, the second loading device automatically loads the mounting frames 12, and the pressing device 4 forms a combined component in which the fixing frames 11 and the mounting frames 12 are integrated, realizing the automated assembly of the mounting frames 12 and the fixing frames 11 and improving the assembly efficiency.

[0049] Another improvement point of this embodiment is that the second feeding device is directly connected to the assembly process equipment after the injection molded parts are discharged from the injection molding machine. It can complete the feeding of the mounting bracket 12 and its assembly with the fixing bracket 11 before the materials are packed into boxes, achieving economic benefits such as optimizing the subsequent product assembly process, reducing waste in material turnover, and saving labor costs. It can also achieve unmanned participation in assembly and feeding, reduce the labor operation intensity, and maximize the utilization of site space.

[0050] It can be understood that the feeding manipulator may not directly take the mounting bracket 12 from the injection molding machine. Instead, after taking out the mounting bracket 12 from the injection molding machine, it can be sent to the assembly device through the transmission mechanism of the second feeding device. Or, if the second feeding device does not adopt the manipulator method, other methods can be used to replace the manipulator to pick up and deliver the mounting bracket 12, which all fall within the protection scope of the present invention.

[0051] As Figures 5-6 shown, the moving device is used to drive the fixing bracket 11 to move. The second feeding device aligns the mounting holes 13 on the mounting bracket 12 with those on the fixing bracket 11 and places the mounting bracket 12 on the mounting holes 13. The pressing device 4 is used to press the mounting bracket 12 into the mounting holes 13 to form an integrated assembly of the mounting bracket 12 and the fixing bracket 11.

[0052] Specifically, the mobile device includes a transverse movement device 5 and a lifting device 6. The lifting device 6 cooperates with the second feeding device. The lifting device 6 is used to drive the fixed frame 11 to rise and leave the first carrier 51. The loading manipulator is used to directly take out the formed mounting frame 12 in the injection molding machine and align it with the fixed frame 11 in the lifting device 6. This not only facilitates direct docking with the injection molding machine but also serves to take away and temporarily store the fixed frame 11, ensuring that other workstations can operate continuously according to the predetermined rhythm. Specifically, the transverse movement device 5 includes a first carrier 51, a second carrier 52, and a third carrier 53 that are linked, and a transverse movement cylinder 55. The transverse movement cylinder 55 can reciprocate between a first position and a second position and drive the first carrier 51, the second carrier 52, and the third carrier 53 to move respectively when moving. The first carrier 51, the second carrier 52, and the third carrier 53 are respectively slidably arranged on the track 56. A positioning plate 57 is provided on the first carrier 51, and the positioning plate 57 cooperates with a first positioning block 58 and a second positioning block 59 respectively. When the transverse movement cylinder 55 moves to the first position and the second position, the positioning plate 57 contacts and limits the first positioning block 58 and the second positioning block 59 respectively. A first working station 101, a second working station 102, a third working station 103, and a fourth working station 104 are sequentially arranged in the moving direction of the first carrier 51, the second carrier 52, and the third carrier 53. When the transverse movement cylinder 55 moves to the first position, the first carrier 51, the second carrier 52, and the third carrier 53 are respectively located at the first working station 101, the second working station 102, and the third working station 103. When the transverse movement cylinder 55 moves to the second position, the first carrier 51, the second carrier 52, and the third carrier 53 are respectively located at the second working station 102, the third working station 103, and the fourth working station 104. The first feeding device, the lifting device 6, and the pressing device 4 are respectively arranged above the first working station 101, the second working station 102, and the third working station 103. A blanking device is provided above the fourth working station 104. The fixed frame 11 in the first feeding device sequentially falls into the first carrier 51. The first carrier 51 is used to send the fixed frame 11 to the second working station 102. The lifting device 6 at the second working station 102 is used to take away the fixed frame 11 in the first carrier 51. The second feeding device is used to align the mounting frame 12 with the mounting hole 13 on the fixed frame 11 and place the mounting frame 12 on the mounting hole 13. The lifting device 6 then places the mounting frame 12 and the fixed frame 11 on the second carrier 52. The second carrier 52 is used to send the mounting frame 12 and the fixed frame 11 to the third working station 103. The pressing device 4 at the third working station 103 is used to press the mounting frame 12 into the mounting hole 13 to form an integrated assembly of the mounting frame 12 and the fixed frame 11, and send the assembly to the third carrier 53. The third carrier 53 is used to send the assembly to the fourth working station 104. The blanking device at the fourth working station 104 is used to take away the assembly on the third carrier 53.Preferably, two sets of first carriers 51, two sets of second carriers 52, and two sets of third carriers 53 are provided on the transverse movement device 5. When each mechanism operates, two sets of fixing frames 11 and mounting frames 12 are simultaneously operated, which can improve the efficiency of the assembly work.

[0053] As Figure 7 shown, the loading tooling 3 is detachably connected to the material distribution device 2. The loading tooling 3 can be first filled with the fixing frames 11 manually, and then the loading tooling 3 is inverted above the material distribution device 2 so that the fixing frames 11 enter the material distribution device 2 in sequence. Specifically, a material distribution end and a limiting end are respectively provided at both ends of the guide rail structure 31. A blocking structure 32 is provided at the limiting end. When the limiting end is located below the material distribution end, the blocking structure 32 is used to block the movement of the fixing frames 11, so that a plurality of fixing frames 11 can be respectively sleeved on the guide rail structure 31 and stacked above the blocking structure 32. When the loading tooling 3 is inverted above the material distribution device 2, the material distribution end is located below the limiting end, and the plurality of fixing frames 11 respectively move towards the material distribution end and fall into the material distribution device 2. The operation difficulty can be reduced and the equipment cost can be reduced through manual cooperation. Of course, the fixing frames 11 can also be sequentially placed on the loading tooling 3 by means of a manipulator, and then the loading tooling 3 can be inverted above the material distribution device 2 by means of a manipulator, which both belong to the protection scope of the present invention. In addition, the limiting end can also be not provided, and the loading tooling 3 is directly installed above the material distribution device 2, and the fixing frames 11 are loaded through the original limiting end position.

[0054] Furthermore, the loading tooling 3 includes four of the guide rail structures 31, and a quadrilateral support plate 33 provided between the four guide rail structures 31. The four guide rail structures 31 respectively include two first guide plates 311 arranged vertically, and a second guide plate 312 connected between the two first guide plates 311 of each. The second guide plates 312 of the four guide rail structures 31 are respectively in a curved surface shape, and the inner sides respectively cooperate with the four vertex angles of the support plate 33. The inner sides of the first guide plates 311 of the four guide rail structures 31 respectively cooperate with the four side edges of the support plate 33. The outer sides of the first guide plates 311 and the second guide plates 312 respectively slide cooperate with the rounded corners 14 of the inner circle of the fixing frame 11. The four guide rail structures 31 can stably guide the fixing frames 11, and the support plate 33 can support the four guide rail structures 31, and the overall structure has better stability.

[0055] Further, the support plate 33 is detachably connected to the guide rail structure 31 and the blocking structure 32 respectively, which can facilitate the adjustment of the size of the loading tooling 3 to match various fixing frames 11 of different sizes. Specifically, a first connection hole for cooperating with the first connector 331 is provided on the side edge of the support plate 33, and a second connection hole 333 for cooperating with the second connector 332 is provided on the side surface of the support plate 33. The first connector 331 is used to connect the support plate 33 to the first guide plate 311 of the guide rail structure 31, and the second connector 332 is used to connect the support plate 33 to the blocking structure 32. Third connection holes 334 and fourth connection holes corresponding to the first connector 331 and the second connector 332 are respectively provided on the first guide plate 311 and the blocking structure 32. The support plate 33 can adjust its shape and size according to the size of the fixing frame 11, and then adjust the size between the guide rail structures 31. Then, by connecting the support plate 33 to the blocking structure 32, it can be adapted to various fixing frames 11 of different sizes, and it also has the characteristics of simple structure and convenience.

[0056] As Figure 8 shown, the material distribution device 2 includes a material distribution base 21, and a material distribution cavity is provided in the material distribution base 21. The guide rail structure 31 is inserted into the material distribution cavity so that the fixing frame 11 can slide into the material distribution cavity. A support structure is provided above the material distribution base 21 for supporting and fixing the guide rail structure 31. In this embodiment, a positioning pin 23 is provided on the support structure, and a positioning hole 24 for sleeving on the positioning pin 23 for limit cooperation is provided on the blocking structure 32 of the guide rail structure 31. The material distribution end of the guide rail structure 31 is inserted into the material distribution cavity, and the positioning hole 24 is sleeved on the positioning hole 24, then the fixation of the guide rail structure 31 can be realized, and it can be directly taken and placed, with convenient assembly and high efficiency. The blocking structure 32 can not only play a role in limiting the fixing frame 11, but also play a role in limiting the entire loading tooling 3 during reverse buckling.

[0057] Specifically, the support structure includes a support frame with a U-shaped cross-section. The guide rail structure 31 is installed and limited within the feeding space of the U-shaped structure. A positioning pin 23 is provided at the top of the support frame. In this embodiment, the support frame includes two L-shaped baffles and a plurality of brackets 25 respectively connected to the two baffles. The two baffles respectively include a first baffle edge 221 and a second baffle edge 222 connected to each other. The second baffle edges 222 of the two baffles are arranged at intervals and flush with each other. The first baffle edges 221 of the two baffles are arranged opposite to each other. The two baffles enclose the feeding space of the U-shaped structure. The guide rail structure 31 can be inserted into the inner side of the feeding space. The bracket 25 has a U-shaped structure and includes two first support rods arranged opposite to each other and a second support rod connected between the two first support rods. The first support rods are respectively connected to the first baffle edges 221 of the two baffles. The second support rods are respectively connected to the second baffle edges 222 of the two baffles. A plurality of brackets 25 are arranged along the length direction of the baffle. The distance between the two first support rods is smaller than the width of the blocking structure 32. Positioning pins 23 are respectively provided on the two first support rods of the uppermost bracket 25. The uppermost bracket 25 can not only be directly in limit fit with the blocking structure 32, but also be in limit fit with the blocking structure 32 through the positioning pins 23, which can fix the feeding tooling 3, effectively reduce the shaking of the feeding tooling 3, and also has the characteristics of simple structure and convenient operation.

[0058] Preferably, the distance between the two first support rods of the bracket 25 is greater than the distance between the first baffle edges 221 of the two baffles, and one of the baffles is detachably connected to the bracket 25, so that the distance between the two first baffle edges 221 can be adjusted, thereby realizing the adaptation to fixing frames 11 of various sizes.

[0059] Such as Figure 9As shown in the figure, the limiting mechanism includes a limiting block 201 that can move into the material distribution cavity to limit and fix the fixing frame 11 in the material distribution cavity or move out of the material distribution cavity to release the fixing frame 11. The material distribution device 2 of this embodiment includes two sets of limiting mechanisms, namely a material distribution limiting mechanism 27 and a blanking limiting mechanism 28. The blanking limiting mechanism 28 is arranged below the material distribution limiting mechanism 27. The two sets of limiting mechanisms respectively include two relatively arranged limiting blocks 201, and a material distribution cylinder 202 for driving the two limiting blocks 201 of each to clamp and separate. When both the material distribution limiting mechanism 27 and the blanking limiting mechanism 28 are clamped, the two fixing frames 11 at the bottom of the feeding tooling 3 can be limited. When only the blanking limiting mechanism 28 is opened, the blocked fixing frame 11 can be released. When the blanking limiting mechanism 28 is clamped again and only the material distribution limiting mechanism 27 is opened, the rear fixing frame 11 can be released to the position blocked by the blanking limiting mechanism 28. When the material distribution limiting mechanism 27 is clamped again, the third fixing frame 11 originally below is limited. At this point, it returns to the state when both the material distribution limiting mechanism 27 and the blanking limiting mechanism 28 are clamped, and then opening the blanking limiting mechanism 28 starts the cyclic operation. The material distribution cylinder 202 is installed on the material distribution seat 2. The material distribution seat 2 is provided with a limiting hole, and the material distribution cylinder 202 drives the limiting block 201 to extend into or out of the material distribution cavity through the limiting hole. As can be seen from the figure, the first carrier 51 is located below the material distribution seat 2, and the fixing frame 11 that has been distributed by the material distribution device 2 can slide into the first carrier 51.

[0060] It can be understood that the material distribution device 2 can also adopt other methods. For example, on one side are fixed parts, and on the other side, a limiting block 201 controlled by a cylinder is used to press the fixing frame 11 against the limiting block 201, or the shape of the limiting block 201 is adjusted so that the limiting block 201 can directly insert under the fixing frame 11, as long as it can block the fall of the fixing frame 11 at a predetermined time to make the fixing frame 11 fall into the first carrier 51 below in sequence.

[0061] As Figure 10 As shown in the figure, the pressing device 4 includes a pressing plate 41 and a downward pressing cylinder 42 for driving the pressing plate 41 to move. The pressing plate 41 is used to push the mounting frame 12 so that the mounting frame 12 is inserted into the mounting hole 13 of the fixing frame 11 to form an integrated assembly.

[0062] Further, a suction cup device 43 is provided on the pressing plate 41. The suction cup device 43 is used to suck away the assembled assembly after the assembly is assembled. The fixing frame 11 and the mounting frame 12 form an integral assembly in the second carrier 52. The suction cup device 43 sucks away the assembly in the second carrier 52. When the third carrier 53 moves below, the assembly is then placed into the third carrier 53, and the third carrier 53 drives the assembly to unload. Of course, the suction cup device 43 can also be provided separately and driven to move up and down by a separate cylinder, or a mechanical gripper or a robot can be provided to replace the suction cup device 43, which all fall within the protection scope of the present invention.

[0063] As Figure 11 shown, the lifting device 6 includes clamping members 61 arranged oppositely, and a jaw cylinder 62 for driving the two clamping members 61 to clamp and release. The jaw cylinder 62 is connected to a lifting cylinder 63. The lifting cylinder 63 is used to drive the jaw cylinder 62 to move up and down. When the two clamping members 61 descend to both sides of the fixing frame 11, the jaw cylinder 62 can drive the two clamping members 61 to clamp the fixing frame 11, and then the lifting cylinder 63 drives the fixing frame 11 to leave the first carrier 51. After the second feeding device places the mounting frame 12 on the fixing frame 11 and the second carrier 52 moves below the lifting clamping members 61, the lifting cylinder 63 drives the clamping members 61 to descend again. After the clamping members 61 are opened, the fixing frame 11 and the mounting frame 12 are placed into the second carrier 52, and then the second carrier 52 moves to the third station 103 for assembly.

[0064] The assembly process of this embodiment mainly includes a cross - moving cylinder 55 that reciprocates between a first position and a second position. The cross - moving cylinder 55 is provided with a first carrier 51, a second carrier 52, and a third carrier 53;

[0065] When the cross - moving device 5 moves to the first position, the first carrier 51, the second carrier 52, and the third carrier 53 are respectively located at the first station 101, the second station 102, and the third station 103, and simultaneously start step S11, step S12, and step S13 respectively:

[0066] Step S11 includes sending the fixing frame 11 to the first carrier 51 located at the first station 101;

[0067] Step S12 includes placing the fixing frame 11 and the mounting frame 12 in step S22 into the second carrier 52;

[0068] Step S13 includes sending the assembly at the position to be taken in step S33 to the third carrier 53;

[0069] When the transverse movement device 5 moves to the second position, the first carrier 51, the second carrier 52, and the third carrier 53 are respectively located at the second working station 102, the third working station 103, and the fourth working station 104, and steps S21, S22, and S23 start simultaneously:

[0070] Step S21 includes removing the fixing bracket 11 placed in the first carrier 51 in step S11 and placing the mounting bracket 12 on the fixing bracket 11;

[0071] Step S22 includes forming an assembly of the fixing bracket 11 and the mounting bracket 12 placed in the second carrier 52 in step S12 and sending the assembly to the position to be picked up;

[0072] Step S23 includes removing the assembly in the third carrier 53 in step S13.

[0073] In this embodiment, through the repeated action of the transverse movement cylinder 55, the first carrier 51, the second carrier 52, and the third carrier 53 act between the mechanisms respectively, and cooperate with the action beats of each mechanism to realize the synchronous progress of the actions of each working station. This not only greatly shortens the blanking beat of the overall equipment and has the characteristics of high efficiency, but also has a simple and stable process, a small occupied space, and a low overall manufacturing cost. Specifically, first, the fixing bracket 11 is automatically sleeved and set in the feeding tooling 3 by manual or manipulator, etc., and then the feeding tooling 3 of the fixing bracket 11 is inverted and installed on the supporting structure and fixed by the positioning pin 23 on the supporting structure. The fixing bracket 11 enters the material distribution cavity through the guidance of the feeding tooling 3. The material distribution limiting mechanism 27 and the blanking limiting mechanism 28 are alternately clamped and opened through program control to realize the separation of the lowermost fixing bracket 11, and it drops into the cavity of the first carrier 51. At this time, the transverse movement cylinder 55 is located at the first position, and the first carrier 51 is located at the first working station 101. The above cycle is repeated to distribute the fixing bracket 11. Then, the transverse movement cylinder 55 of the transverse movement device 5 is triggered by a signal to act and reach the second position state, so that the first carrier 51 reaches the second working station 102 for docking with the mounting bracket 12. The lifting device 6 performs a descending action, and the clamping member 61 is controlled by the clamping jaw cylinder 62 to clamp the fixing bracket 11. After obtaining the clamping feedback signal, the lifting cylinder 63 drives the fixing bracket 11 to rise and leave the first carrier 51, and then reaches the position where the mounting bracket 12 is placed. Through the on-line signal, the feeding manipulator serving as the second feeding device is controlled to transfer the mounting bracket 12 out of the injection molding machine and place it on the fixing bracket 11 for initial mating and positioning.

[0074] Meanwhile, the transverse movement cylinder 55 operates and reaches the first position, driving the first carrier 51 back to the first working station 101 and positioning it below the material distribution device 2, preparing for the next material receiving operation of the fixing bracket 11. At the same time, the second carrier 52 reaches the second working station 102. After the signal feedback indicating that the second carrier 52 is in place, the lifting cylinder 63 descends, places the mounting bracket 12 and the fixing bracket 11 into the cavity of the second carrier 52, and sequentially performs the operations of loosening the fixing bracket 11 by the clamping member 61 and raising the lifting cylinder 63.

[0075] After the lifting cylinder 63 rises to the in-place position, the transverse movement cylinder 55 operates and reaches the second position. At this time, the first carrier 51 is at the second working station 102, and the second carrier 52 reaches the third working station. After the transverse movement cylinder 55 reaches the in-place position, the pressing cylinder 42 operates to drive the pressing plate 41 to push the mounting bracket 12, so that the mounting bracket 12 and the fixing bracket 11 form an integrated assembly and maintain the pressing state. After the signal feedback indicates that the pressing is completed, the suction cup device 43 sucks the integrated assembly through negative pressure, and then the pressing cylinder 42 rises, driving the integrated assembly away from the second carrier 52.

[0076] Then, the above actions are repeated. The lifting device 6 at the second working station 102 raises the fixing bracket 11 in the first carrier 51. The feeding manipulator places the mounting bracket 12 on the fixing bracket 11 for initial fitting and positioning. After completing the rising and sucking operation at the third working station 103 and the rising and material receiving operation at the second working station 102, the transverse movement cylinder 55 performs an operation and reaches the first position. At this time, the first carrier 51 returns to the first working station 101 for the material receiving operation of the fixing bracket 11. The second carrier 52 returns to the second working station 102 and places the mounting bracket 12 and the fixing bracket 11 into the second carrier 52. The third carrier 53 reaches the third working station 103 for the material discharging operation, that is, the previously taken integrated assembly is placed back into the third carrier 53. After completing the material receiving and discharging operations at each working station above, the transverse movement cylinder 55 operates and reaches the second position. At this time, the first carrier 51 reaches the second working station 102 to perform the rising and material receiving operation. The second carrier 52 reaches the third working station 103 to perform the pressing and rising and sucking of the integrated assembly operation. The third carrier 53 reaches the fourth working station 104. At the fourth working station 114, the discharging device grabs the integrated assembly from the third carrier 53 through the robot grabbing component, docks with the material packing equipment, and completes the discharging operation of the integrated assembly. Thus, a production cycle of a material component is completed.
