Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of automation equipment, and in particular to a switch assembling device. BACKGROUND

[0002] A switch refers to an electronic component for controlling the conduction of an electric circuit, interrupting the current, or making the current flow to other circuits, and can be divided into micro switches, boat switches, toggle switches, button switches, membrane switches, and point switches according to the structure.

[0003] In related technologies, as shown in Figure 1 and Figure 2 a switch is disclosed, which includes a bottom shell 11, a shell outer pin 12 and a shell inner pin 13 inserted in the bottom shell 11, a reset spring 14 located in the bottom shell 11, a spring sheet 15 pressed on the reset spring 14, a button 16 located on the side of the spring sheet 15 away from the reset spring 14, and a cap 17 capped on the bottom shell 11, wherein the shell outer pin 12 and the shell inner pin 13 are both provided with two and are distributed in parallel.

[0004] When assembling the above-mentioned switch, two shell outer pins 12 need to be inserted into the bottom shell 11 first, and then the bottom shell 11 is turned over by 180°, and then two shell inner pins 13 are inserted into the bottom shell 11; then the reset spring 14, the spring sheet 15 and the button 16 are sequentially assembled into the bottom shell 11, and finally the cap 17 is capped on the bottom shell 11. After assembly, one end of the shell outer pin 12 and the shell inner pin 13 is located on the outside of the bottom shell 11, the reset spring 14 and the spring sheet 15 are located inside the bottom shell 11, and one end of the button 16 extends outward through the cap 17.

[0005] However, due to the complex structure and cumbersome assembly process of the above-mentioned switch, in related technologies, manual installation by workers is often required when assembling the above-mentioned switch, and the assembly efficiency is low, which needs to be improved. SUMMARY

[0006] In order to improve the assembly efficiency, the present application provides a switch assembling device.

[0007] The switch assembling device provided by the present application adopts the following technical scheme:

[0008] A switch assembling device comprises

[0009] A bottom shell loading mechanism comprises a bottom shell material channel for conveying the bottom shell, a processing material channel located on one side of the bottom shell material channel, and a shell loading assembly for feeding the bottom shell in the bottom shell material channel into the processing material channel.

[0010] A first loading mechanism is used to load the shell outer pin into the bottom shell.

[0011] The turnover mechanism comprises a turnover channel communicated with the processing channel, and a turnover power member for driving the turnover channel to rotate;

[0012] The second feeding mechanism is used for loading the inner pin into the bottom shell;

[0013] The pushing mechanism is used for driving the bottom shell in the processing channel to pass through the first feeding mechanism, the turnover mechanism and the second feeding mechanism in sequence.

[0014] The rotating disc is provided with a plurality of processing seats for the bottom shell to extend into in the circumferential direction, and the processing seat is provided with an anti-falling assembly for limiting the upward movement of the bottom shell.

[0015] The first clamping mechanism is used for loading the bottom shell in the processing channel into the processing seat.

[0016] The spring feeding mechanism is used for loading the return spring into the bottom shell.

[0017] The elastic sheet feeding mechanism is used for loading the elastic sheet into the bottom shell.

[0018] The button feeding mechanism is used for loading the button into the bottom shell.

[0019] The cap feeding mechanism is used for covering the cap on the bottom shell; the anti-falling assembly is linked with the cap feeding mechanism, and when the cap feeding mechanism works, the anti-falling assembly releases the limitation on the bottom shell in the processing seat.

[0020] The second clamping mechanism is used for moving the finished product out of the processing seat.

[0021] The rotating mechanism is used for driving the rotating disc to rotate in the circumferential direction, so that the processing seat passes through the first clamping mechanism, the spring feeding mechanism, the elastic sheet feeding mechanism, the button feeding mechanism, the cap feeding mechanism and the second clamping mechanism in sequence.

[0022] When the switch is assembled, the bottom shell in the bottom shell channel is first sent into the processing channel by the upper shell assembly, and then is sent to the first feeding mechanism, the turnover mechanism and the second feeding mechanism in sequence by the pushing mechanism. The first feeding mechanism can load the outer pin into the bottom shell to realize the automatic installation of the outer pin; after the bottom shell is moved into the turnover channel along the processing channel, the turnover power member is started to drive the turnover channel to turn the bottom shell by 180°; and the second feeding mechanism can load the inner pin into the bottom shell to realize the automatic installation of the inner pin.

[0023] When the rotating mechanism is working, the rotating disc drives the machining seat to rotate circumferentially, so that each machining seat passes through the first clamping mechanism, the spring feeding mechanism, the spring sheet feeding mechanism, the button feeding mechanism, the cap feeding mechanism and the second clamping mechanism in turn. The first clamping mechanism can load the bottom shell in the machining seat, the spring feeding mechanism can load the return spring into the bottom shell, the spring sheet feeding mechanism can load the spring sheet into the bottom shell, the button feeding mechanism can load the button into the bottom shell, and the cap feeding mechanism can connect the cap to the bottom shell, thereby realizing automatic installation of each part in the switch. After assembly is completed, the second clamping mechanism can move the finished product out of the machining seat, thereby realizing automatic unloading of the switch. The above assembly method does not require manual operation by workers, has high automation degree and assembly efficiency, and is beneficial to batch assembly production of the switch.

[0024] When the bottom shell is loaded into the machining seat by the first clamping mechanism, the anti-extraction assembly limits upward movement of the bottom shell, so that the bottom shell does not move out of the machining seat in the subsequent process of installing the return spring, the spring sheet and the button, thereby improving the stability of the bottom shell. Since the anti-extraction assembly is linked with the cap feeding mechanism, when the cap feeding mechanism is working, the anti-extraction assembly automatically releases the limitation on the bottom shell in the machining seat, so that the anti-extraction assembly does not affect installation of the cap.

[0025] Optionally, the shell pushing mechanism comprises a shell pushing rod, a shell pushing power member for driving the shell pushing rod to move along the extension direction of the machining channel, a plurality of shell pushing blocks rotatably arranged on the shell pushing rod, and a shell pushing spring connected between the shell pushing blocks and the shell pushing rod, wherein the shell pushing spring is used to drive the shell pushing blocks to extend out of the shell pushing rod, and the shell pushing blocks are provided with guide inclined surfaces on the sides away from the bottom shell along the advancing direction of the machining channel.

[0026] By adopting the above technical solution, when the shell pushing power member is working, the shell pushing rod reciprocates along the extension direction of the machining channel. When the shell pushing rod moves towards the direction where the first feeding mechanism, the turnover mechanism and the second feeding mechanism are distributed, the shell pushing blocks gradually push the bottom shell towards the first feeding mechanism, the turnover mechanism and the second feeding mechanism, so as to realize orderly feeding of the bottom shell. When the shell pushing rod moves towards the direction away from the distribution of the first feeding mechanism, the turnover mechanism and the second feeding mechanism, the guide inclined surfaces contact the bottom shell and compress the shell pushing spring connected with the shell pushing blocks, so that the shell pushing blocks do not push back the bottom shell when they are reset. After the shell pushing blocks are separated from the bottom shell, the elastic force of the shell pushing spring pushes the shell pushing blocks out of the shell pushing rod, so as to facilitate the next pushing.

[0027] Optionally, a plurality of limiting assemblies are arranged in the machining channel, and each limiting assembly comprises a mounting block fixed on the machining channel, a limiting block located on the side of the mounting block facing the shell pushing rod, and a limiting spring for driving the limiting block to move towards the shell pushing rod, wherein both ends of the limiting block along the extension direction of the machining channel are provided with chamfers.

[0028] By adopting the technical scheme, when the bottom shell travels along the processing material channel, the limiting spring drives the limiting block to abut against the adjacent bottom shell, so as to prevent the bottom shell from traveling beyond the distance under the action of its own inertia when feeding, and facilitate the accurate movement of the bottom shell.

[0029] Optionally, the first feeding mechanism comprises two pin material channels for conveying the shell external pins, a pin sleeve for the two shell external pins to extend into, a pre-assembly component for driving the shell external pins in the two pin material channels to extend into the pin sleeve, an upper pin assembly for pushing the shell external pins in the pin sleeve into the bottom shell, and a conversion assembly for driving the pin sleeve to be alternatively moved to the pre-assembly component or the upper pin assembly, and the upper pin assembly is located directly above the processing material channel.

[0030] By adopting the technical scheme, when the shell external pins are installed, the pin sleeve is first moved to the pre-assembly component by the conversion assembly, and then the pre-assembly component drives the shell external pins in the pin material channel to extend into the pin sleeve; then the conversion assembly moves the pin sleeve to the upper pin assembly, and finally the upper pin assembly works to push the shell external pins into the bottom shell located directly below, so that the automatic installation of the shell external pins can be realized, and the installation speed is fast and the precision is high.

[0031] Optionally, the pre-assembly component comprises a pre-assembly frame, two pre-assembly blocks horizontally slidingly arranged on the pre-assembly frame, a pre-assembly power member for driving the two pre-assembly blocks to move towards each other, a pre-assembly elastic member for driving the two pre-assembly blocks to move away from each other, a pre-push rod vertically slidingly arranged on the pre-assembly frame, and a pre-push power member for driving the pre-push rod to vertically move, and a pre-assembly groove for the shell external pin to extend into is formed in the side wall of the pre-assembly block facing the pin material channel, and the pre-assembly block can be moved to a state of aligning the pre-assembly groove with the adjacent pin material channel under the action of the pre-assembly elastic member, or moved to a state of aligning the pre-assembly groove with the pre-push rod under the action of the pre-assembly power member.

[0032] By adopting the technical scheme, in the initial state, the two pre-assembly blocks are located at the positions of aligning the pre-assembly groove with the adjacent pin material channel, and after the shell external pin in the pin material channel moves into the pre-assembly groove, the pre-assembly power member drives the two pre-assembly blocks to move towards each other, so that the shell external pin in the pre-assembly groove is aligned with the pre-push rod. Then the pre-push power member is started, and the pre-push rod pushes the shell external pin into the pin sleeve, so as to transfer the shell external pin in the pin material channel to the pin sleeve, so that the upper pin assembly can synchronously push the two shell external pins into the bottom shell, and the assembly efficiency is high.

[0033] Optionally, the pin sleeve comprises a base sleeve, a connecting rod vertically slidingly arranged in the base sleeve, two push rods fixed on the lower side of the connecting rod, and a fixed block fixed at the bottom end of the base sleeve, a fixed hole for the shell external pin to vertically pass through is formed in the fixed block, each fixed hole is located directly below the adjacent push rod, and the fixed hole is communicated with an air pipe, the upper pin assembly is used to drive the connecting rod to move downward, and a reset elastic member for driving the connecting rod to move upward is arranged on the base sleeve.

[0034] By adopting the technical scheme, when the preassembly component is in operation, the shell outer pin is pushed into the fixing hole, if the end of the air pipe away from the fixing hole is connected to the air pump, when the air pump is controlled to suck air, negative pressure is formed in the fixing hole and the shell outer pin is sucked tightly in the pin sleeve, so that the pin sleeve is prevented from falling off the shell outer pin when moving. After the pin sleeve moves to the position right below the needle assembly, the needle assembly is started to move the connecting rod downward, the push rod moves downward synchronously and pushes the shell outer pin into the bottom shell, so that the installation of the shell outer pin is realized. After the needle assembly returns, the reset elastic member drives the connecting rod to move upward, so that the connecting rod and the push rod are automatically reset, so that the push rod is prevented from affecting the next group of shell outer pins to extend into the fixing hole.

[0035] Optionally, the anti-falling assembly comprises two anti-falling blocks horizontally slidingly arranged on the machining seat, a lifting block vertically slidingly arranged on the machining seat, and an anti-falling spring arranged between the anti-falling blocks and the machining seat, the anti-falling spring is used to drive the two anti-falling blocks to move towards each other, so that the anti-falling blocks move to the position right above the bottom shell of the machining seat, and an end of the anti-falling block close to the lifting block and / or the lifting block is provided with a first inclined surface; a lifting power member for driving the lifting block to move upward is arranged at the first clamping mechanism, and the cap cover feeding mechanism comprises a cap cover rack, a reset rack vertically slidingly arranged on the cap cover rack, and a reset power member for driving the reset rack to vertically move, and the reset rack is fixed with a first reset block for pushing the lifting block to move downward.

[0036] By adopting the technical scheme, after the bottom shell moves into the machining seat, the lifting power member is used to drive the lifting block to move upward, so that the lifting block is separated from the anti-falling block, and then the anti-falling blocks move towards each other and move to the position right above the bottom shell under the action of the anti-falling spring, so that the separation of the bottom shell and the machining seat is limited.

[0037] When the cap cover feeding mechanism is in operation, after the reset power member drives the reset rack to move downward, the first reset block pushes the lifting block downward, so that the lifting block pushes the two anti-falling blocks to move away from each other, so that the anti-falling blocks move out of the position right above the bottom shell, so as to automatically unlock the anti-falling assembly, thereby facilitating the movement of the finished product out of the machining seat after assembly is completed.

[0038] Optionally, the machining seat is further provided with a positioning assembly, the positioning assembly comprises two positioning blocks horizontally slidingly arranged on the machining seat, two lifting blocks vertically slidingly arranged on the machining seat, and a positioning spring arranged between the positioning blocks and the machining seat, the positioning spring is used to drive the two positioning blocks to move away from each other, and an end of the positioning block close to the adjacent lifting block and / or the lifting block is provided with a second inclined surface; a lifting power member for driving the lifting block to move upward is arranged at the spring feeding mechanism, and the reset rack is fixed with a second reset block for pushing the lifting block to move downward; when the lifting block moves upward, the two positioning blocks move towards each other to form an installation gap for the reset spring to vertically pass through, and the shape of the installation gap is matched with the shape of the button.

[0039] By adopting the technical scheme, when the processing seat is in the first clamping mechanism, the two positioning blocks are in the position with the largest spacing under the action of the positioning spring, the bottom shell can pass through the gap between the two positioning blocks and extend into the bottom shell. After the processing seat moves to the spring feeding mechanism, the lifting block is driven to move upward by the lifting power piece, the lifting block will contact the positioning block, and the two positioning blocks move towards each other to form the installation gap. At this time, the positioning block plays a role of secondary limiting, so that the bottom shell is not only limited by the anti-drop block, and the limiting effect is good, and the stability of the bottom shell is high.

[0040] Optionally, the spring feeding mechanism comprises an upper spring frame, a material pipe for conveying the reset spring, a transition block and a top rod vertically slidingly arranged on the upper spring frame, a transition power piece for driving the transition block to vertically move, a top pressing power piece for driving the top rod to vertically move, a horizontal slidingly arranged flat pushing block on the upper spring frame, and a flat pushing power piece for driving the flat pushing block to horizontally move. The transition block is fixed with a transition pipe in communication with the outlet of the material pipe, the flat pushing block is located on the lower side of the transition pipe and is provided with a flat pushing hole for vertically extending the reset spring, and the upper spring frame is provided with a gap pipe located directly below the top rod. The flat pushing block can be moved to the state that the flat pushing hole is aligned with the gap pipe under the action of the flat pushing power piece.

[0041] By adopting the technical scheme, in the initial state, the transition pipe is in a state of communication with the flat pushing hole, and the reset spring in the material pipe can enter the flat pushing hole along the transition pipe. When installing the reset spring, the transition pipe is first driven to move upward by the transition power piece, then the flat pushing block is driven to move towards the gap pipe by the flat pushing power piece, so that the flat pushing hole is aligned with the gap pipe, and finally the top rod is driven to move downward by the top pressing power piece. The top rod pushes the reset spring into the bottom shell, thereby realizing the installation of the reset spring one by one.

[0042] Optionally, the spring piece feeding mechanism comprises an upper piece frame, a spring piece material channel arranged on the upper piece frame for conveying the spring piece, a movable block horizontally slidingly arranged on the upper piece frame, an activity cylinder for driving the movable block to horizontally move, an upper piece block slidingly connected to the upper piece frame, a vertical pushing power piece for driving the upper piece block to vertically move, and a horizontal pushing power piece for driving the upper piece block to horizontally move. The movable block is provided with a movable hole for moving the spring piece in the spring piece material channel, the extension direction of the movable hole is perpendicular to the extension direction of the spring piece material channel, and the upper piece block is connected with an assembly head for sucking or releasing the spring piece in the movable hole.

[0043] By adopting the technical scheme, when the movable hole is aligned with the shell fragment channel, the shell fragment will enter the movable hole and move to a state of being misaligned with the shell fragment channel under the action of the movable cylinder. After the assembly head sucks the shell fragment, the horizontal pushing power member is used to drive the upper fragment block to move horizontally, so that the assembly head moves to the adjacent processing seat, the vertical pushing power member is used to drive the upper fragment block to move downward, so that the shell fragment sucked on the assembly head extends into the processing seat, and finally the assembly head is loosened, so that the automatic installation of the shell fragment is realized.

[0045] 1. When assembling the switch, the first feeding mechanism can install the shell outer pin into the bottom shell, the turnover mechanism can control the bottom shell to turn over 180°, the second feeding mechanism can install the shell inner pin into the bottom shell, the spring feeding mechanism can install the reset spring into the bottom shell, the shell fragment feeding mechanism can install the shell fragment into the bottom shell, the button feeding mechanism can install the button into the bottom shell, and the cap feeding mechanism can cover the cap on the bottom shell, so that the automatic assembly of each part in the switch is realized, and the work efficiency is high.

[0046] 2. When the bottom shell is located in the processing seat, the anti-falling assembly and the positioning assembly can generate multi-stage limiting on the bottom shell, so as to improve the stability of the bottom shell; when the cap feeding mechanism works, the anti-falling assembly and the positioning assembly will reset to the state of releasing the limiting on the bottom shell, so as to avoid affecting the removal of the finished product from the bottom shell.

[0047] 3. When installing the shell outer pin, the pre-assembly assembly will synchronously install the two shell outer pins into the pin sleeve, and after the pin sleeve moves to the needle assembly, the needle assembly will push the shell outer pins in the pin sleeve into the bottom shell, so that the synchronous feeding of the two shell outer pins is realized, and the installation efficiency is high.

[0088] The application will be further described in detail below with reference to all the accompanying drawings.

[0089] The application discloses a switch assembling device, which is used for assembling a switch as shown in Figure 1 and Figure 2 .

[0090] Referring to Figure 3 , the switch assembling device comprises a rack 2 and a bottom shell feeding mechanism 21, a first feeding mechanism 22, a turnover mechanism 23, a second feeding mechanism 24, a dust removal mechanism 25, a lubricating mechanism 26, a shell pushing mechanism 27, a rotating disc 3, a first clamping mechanism 31, a spring feeding mechanism 32, a spring piece feeding mechanism 33, a button feeding mechanism 34, a cap feeding mechanism 35, a second clamping mechanism 36 and a rotating mechanism 37 arranged on the rack 2, wherein the shell pushing mechanism 27 is used for driving the bottom shell 11 to pass through the first feeding mechanism 22, the turnover mechanism 23, the second feeding mechanism 24, the dust removal mechanism 25 and the lubricating mechanism 26 in sequence; the rotating mechanism 37 is used for driving the rotating disc 3 to rotate, so that the bottom shell 11 on the rotating disc 3 passes through the first clamping mechanism 31, the spring feeding mechanism 32, the spring piece feeding mechanism 33, the button feeding mechanism 34, the cap feeding mechanism 35 and the second clamping mechanism 36 in sequence.

[0091] Referring to Figure 4The bottom shell feeding mechanism 21 comprises a horizontally extending bottom shell feeding channel 211, a processing feeding channel 212 arranged in parallel to one side of the bottom shell feeding channel 211, and an upper shell assembly 213 for feeding the bottom shell 11 in the bottom shell feeding channel 211 into the processing feeding channel 212. One end of the bottom shell feeding channel 211 is connected to a vibrating disc containing the bottom shell 11. When the vibrating disc is in operation, the bottom shell 11 will enter the bottom shell feeding channel 211 and be transmitted to the upper shell assembly 213.

[0092] Referring to Figure 4 The upper shell assembly 213 comprises an upper shell block 2131 and an upper shell cylinder 2132 for driving the upper shell block 2131 to reciprocate towards the processing feeding channel 212. The cylinder barrel of the upper shell cylinder 2132 is fixed to the frame 2, and the piston rod is directed towards the processing feeding channel 212 and is fixedly connected to the upper shell block 2131. A through slot is formed in the upper shell block 2131 for the bottom shell 11 to extend into. When the piston rod of the upper shell cylinder 2132 is shortened, the through slot of the upper shell block 2131 will be aligned with the discharge port of the bottom shell feeding channel 211, so as to facilitate the movement of the bottom shell 11 into the upper shell block 2131. When the piston rod of the upper shell cylinder 2132 is lengthened, the upper shell block 2131 will drive the bottom shell 11 to move towards the processing feeding channel 212, so as to feed the bottom shell 11 into the processing feeding channel 212.

[0093] Referring to Figure 5 , Figure 6 The shell pushing mechanism 27 comprises a shell pushing rod 271, a shell pushing power member 272 for driving the shell pushing rod 271 to reciprocate along the extending direction of the processing feeding channel 212, a plurality of shell pushing blocks 273 rotatably arranged on the shell pushing rod 271, and a shell pushing spring 274 connected between each shell pushing block 273 and the shell pushing rod 271. When the shell pushing spring 274 is in a natural state, one end of the shell pushing block 273 extends out of the shell pushing rod 271. The shell pushing power member 272 is preferably a shell pushing cylinder, wherein the cylinder barrel is fixed to the frame 2, and the piston rod is fixedly connected to the shell pushing rod 271. The extending direction of the piston rod of the shell pushing cylinder is parallel to the extending direction of the processing feeding channel 212.

[0094] Referring to Figure 5 , Figure 6 One side of the shell pushing block 273, which is away from the bottom shell 11 and along the advancing direction of the processing feeding channel 212, is provided with a guide inclined surface 275. The advancing direction refers to the direction from the first feeding mechanism 22 to the turnover mechanism 23. After the bottom shell 11 is moved into the processing feeding channel 212, if the piston rod of the shell pushing power member 272 is lengthened, the shell pushing block 273 will be in contact with the bottom shell 11 and push the bottom shell 11 towards the first feeding mechanism 22. If the piston rod of the shell pushing power member 272 is shortened, the guide inclined surface 275 will be in contact with the bottom shell 11, so that the shell pushing block 273 will retreat into the shell pushing rod 271, so as to prevent the bottom shell 11 from being pushed back by the shell pushing block 273. In actual application, the manufacturer can customize the number and spacing of the shell pushing blocks 273 according to the needs, so that the bottom shell 11 can advance to different mechanisms along the processing feeding channel 212.

[0095] With reference to Figure 6 To further improve the moving accuracy of the bottom shell 11, a plurality of limiting assemblies 4 are arranged in the machining channel 212. Each limiting assembly 4 comprises a mounting block 41 fixed on the machining channel 212, a limiting block 42 located on the side of the mounting block 41 facing the shell pushing rod 271, and a limiting spring 43 for driving the limiting block 42 to move towards the shell pushing rod 271. One end of the limiting spring 43 abuts against the mounting block 41, and the other end abuts against the limiting block 42. Both ends of the limiting block 42 along the extension direction of the machining channel 212 are provided with chamfers. When the bottom shell 11 travels along the machining channel 212, the limiting block 42 will abut against the bottom shell 11 under the action of the limiting spring 43, thereby reducing the displacement difference of the bottom shell 11 due to its own inertia.

[0096] With reference to Figure 4 , Figure 5 The first feeding mechanism 22 comprises two pin channels 221, a pin sleeve 222 for the two shell outer pins 12 to extend into, a pre-assembly assembly 223 for driving the shell outer pins 12 in the two pin channels 221 to synchronously extend into the pin sleeve 222, a needle assembly 224 for pushing the shell outer pins 12 in the pin sleeve 222 into the bottom shell 11, and a conversion assembly 225 for driving the pin sleeve 222 to alternately move to the pre-assembly assembly 223 or the needle assembly 224. The pin channels 221 are connected with a vibrating disc provided with the shell outer pins 12. When the vibrating disc is working, the shell outer pins 12 will move along the pin channels 221 towards the pre-assembly assembly 223.

[0097] With reference to Figure 7 The pre-assembly assembly 223 comprises a pre-assembly frame 2231 fixed on the rack 2, two pre-assembly blocks 2232 horizontally slidingly arranged on the pre-assembly frame 2231, a pre-assembly power member 2233 for driving the two pre-assembly blocks 2232 to move towards each other, a pre-assembly elastic member 2234 for driving the two pre-assembly blocks 2232 to move away from each other, a pre-push rod 2235 vertically slidingly arranged on the pre-assembly frame 2231, and a pre-push power member 2236 for driving the pre-push rod 2235 to vertically move. The side wall of each pre-assembly block 2232 facing the pin channel 221 is provided with a pre-assembly groove 2237.

[0098] With reference to Figure 7 The pre-assembly elastic member 2234 comprises a pre-assembly spring connected between the pre-assembly block 2232 and the pre-assembly frame 2231. When the pre-assembly spring is in a natural state, the pre-assembly groove 2237 is aligned with the adjacent pin channel 221, and the shell outer pin 12 can extend into the pre-assembly groove 2237 along the pin channel 221.

[0099] With reference to Figure 7The preloading power element 2233 includes a through rod 2238 that slides vertically on the preloading frame 2231, and a preloading cylinder 2239 for driving the through rod 2238 vertically. The piston rod of the preloading cylinder 2239 is fixedly connected to the through rod 2238 and faces upward. The top of the through rod 2238 is provided with a preloading inclined surface on the side adjacent to the adjacent preloading block 2232. When the preloading cylinder 2239 drives the through rod 2238 upward, the preloading inclined surface contacts the preloading block 2232, causing the two preloading blocks 2232 to move toward each other and aligning the preloading groove 2237 with the preloading push rod 2235. The pre-push force member 2236 is preferably a pre-push cylinder, the piston rod of the pre-push cylinder is upward and fixedly connected to the pre-push rod 2235. When the pre-push force member 2236 drives the pre-push rod 2235 to move upward, the pre-push rod 2235 will push the bottom shell 11 in the pre-installation groove 2237 out of the pre-installation block 2232.

[0100] Reference Figure 8 The pin sleeve 222 includes a base sleeve 2221, a connecting rod 2222 vertically slidingly arranged in the base sleeve 2221, two push rods 2223 fixed to the lower side of the connecting rod 2222, and a fixed block 2224 fixed to the bottom end of the base sleeve 2221. The fixed block 2224 is provided with two fixing holes 2225 for the outer shell pins 12 to vertically extend into. Each push rod 2223 is located directly above the adjacent fixing holes 2225 and can extend into the fixing holes 2225. The two fixing holes 2225 are interconnected and respectively connected to an air pipe 2226. When in use, the air pipe 2226 is connected to the air pump. When the pin sleeve 222 is moved to the position directly above the pre-assembled component 223, the outer shell pins 12 in the pre-assembled block 2232 are pushed into the fixing holes 2225. If the air pump is controlled to evacuate air, a negative pressure is formed inside the fixing holes 2225, thereby sucking the outer shell pins 12 into the pin sleeve 222.

[0101] Reference Figure 5 、 Figure 8 The conversion assembly 225 includes a conversion cylinder mounted on the frame 2. The piston rod of the conversion cylinder is horizontally arranged and fixedly connected to the base sleeve 2221. When the piston rod of the conversion cylinder is shortened, the pin sleeve 222 is located directly above the pre-assembled assembly 223. When the piston rod of the conversion cylinder is extended, the pin sleeve 222 is located directly below the upper needle assembly 224.

[0102] Reference Figure 5 、 Figure 8The upper needle assembly 224 comprises an upper needle cylinder located directly above the processing channel 212. After the pin sleeve 222 moves directly below the upper needle assembly 224, if the piston rod of the upper needle cylinder is elongated, the piston rod of the upper needle cylinder will be in contact with the connecting rod 2222, and the connecting rod 2222 will drive the push pin rod 2223 to move downward, so as to push the shell outer pin 12 into the bottom shell 11 by the push pin rod 2223. In order to reset the push pin rod 2223, a reset elastic element 2229 for driving the connecting rod 2222 to move upward is arranged on the base sleeve 2221, and the reset elastic element 2229 is preferably a spring.

The turnover channel 231 is connected to the middle part of the processing channel 212, and the turnover power element 232 is preferably a turnover motor with an output shaft fixedly connected to the turnover channel 231. After the bottom shell 11 enters the turnover channel 231, the turnover channel 231 is driven to rotate 180° by the turnover power element 232, and the bottom shell 11 is synchronously turned over 180°.

[0104] Referring to Figure 4 , in order to simplify the production process of the assembly equipment, the second feeding mechanism 24 is identical in structure to the first feeding mechanism 22, and the difference between the two is only that the parts transmitted by the pin channel 221 are different. The function of the second feeding mechanism 24 is to load the shell inner pin 13 into the bottom shell 11.

[0105] Referring to Figure 4 , the dust removal mechanism 25 comprises a dust removal cylinder 251 connected to the upper side of the processing channel 212.

[0107] Referring to Figure 9 , Figure 10 , a plurality of processing seats 5 for the bottom shell 11 to extend into are arranged on the turntable 3 in a circumferential direction. The rotating mechanism 37 can be a rotating motor arranged on the rack 2, and the output shaft of the rotating motor is fixedly connected to the turntable 3. The anti-disengagement assembly 51 and the positioning assembly 52 are arranged on each processing seat 5. When the bottom shell 11 extends into the processing seat 5, the anti-disengagement assembly 51 and the positioning assembly 52 can limit the upward movement of the bottom shell 11, thereby playing a multi-stage positioning role on the bottom shell 11.

When the lifting cylinder 62 drives the vertical rod 61 to move upward, the vertical rod 61 will push the lifting block 512 upward to separate from the anti-falling block 511, and at this time the anti-falling block 511 will move to the top of the bottom shell 11 under the action of the anti-falling spring 513, so as to limit the upward movement of the bottom shell 11 relative to the processing seat 5.

[0110] Referring to Figure 11 , Figure 12 , the positioning assembly 52 includes two positioning blocks 521 horizontally slidingly arranged on the processing seat 5, two lifting blocks 522 vertically slidingly arranged on the processing seat 5, and a positioning spring 523 arranged between each positioning block 521 and the processing seat 5, respectively.

In the initial state, the flat push hole 3271 is aligned with the transition pipe 3231, and the return spring 14 can fall into the flat push hole 3271 along the transition pipe 3231; during feeding, the flat push block 327 is first driven to move towards the turntable 3 by the flat push power element 328 until the flat push hole 3271 is aligned with the clearance pipe 3211, and then the return spring 14 falls into the clearance pipe 3211; and then the top rod 324 is driven to move downwards by the top pressing power element 326, so that the return spring 14 is pushed into the bottom shell 11, thereby realizing the installation of the return spring 14.

A movable hole 3331 is formed in the side wall of the movable block 333 facing the spring piece 15 channel, and the spring pieces 15 can enter the movable hole 3331 along the spring piece 15 channel. After the spring pieces 15 enter the movable hole 3331, the piston rod of the movable cylinder 334 is shortened, and then the movable block 333 drives the spring pieces 15 to move to a position dislocated from the spring piece 15 channel, which is beneficial to the feeding of the spring pieces 15 one by one.

[0121] The implementation principle of the switch assembling device is as follows: when assembling the switch, the bottom shell 11 in the bottom shell material channel 211 is first sent into the processing material channel 212 by the upper shell assembly 213, and then is sent to the first feeding mechanism 22, the turnover mechanism 23, the second feeding mechanism 24, the dust removal mechanism 25 and the lubricating mechanism 26 in sequence by the shell pushing mechanism 27; after the outer shell pin 12 is fed into the bottom shell 11 by the first feeding mechanism 22, the turnover mechanism 23 drives the bottom shell 11 to turn over by 180°, and then the inner shell pin 13 is fed into the bottom shell 11 by the second feeding mechanism 24; then the dust removal mechanism 25 removes the dust in the bottom shell 11, and the lubricating mechanism 26 injects lubricating oil into the bottom shell 11.
