[0027] The technical solution of the present invention has the following advantages:

[0028] 1. The present invention provides an automatic assembly machine for a solenoid valve plug, which realizes the automatic assembly of the solenoid valve plug by rotating the turntable, fixing the gasket and the base through the clamp body, and then installing the pin on the base; secondly, the special-shaped setting of the fixing plate allows different stations to achieve different effects during the rotation of the turntable. Since the environments at different positions are different during the installation process, for example, during the assembly of the gasket and the base, since the size of the first accommodating cavity is adapted to them, there is no need to clamp them, and a loose environment is required for easy installation. When fixing the pin, higher precision is required. In order to prevent the base from shifting in the first accommodating cavity, the second arc surface cooperates with the guide block and the push block, and the push block moves toward one side of the first accommodating cavity. , so that the push block is against the outer wall of the base, forming a clamping and fixing effect, so that the base is firmly fixed and will not shake, which is convenient for subsequent assembly operations. Compared with the cylinder or oil cylinder clamping structure, this structure only relies on the rotational force of the turntable to achieve the clamping and fixing effect, without the need for a cylinder or an oil cylinder, that is, through simple mechanical cooperation, the clamping and fixing effect of the base can be achieved, which can greatly reduce the processing cost of the equipment, and can also release a lot of space for the installation of other automated structures; when it is located in the unloading mechanism, if the base is still firmly clamped at this time, the unloading mechanism cannot realize unloading, so at this time, the push block moves in the opposite direction, and the base is in a loose state, and the unloading mechanism can easily complete the clamping and unloading, automatic installation, and improve assembly efficiency.

[0029] 2. The present invention provides an automatic assembly machine for solenoid valve plugs, wherein the first hooking portion, the second hooking portion, and the first elastic member form an elastic connection effect between the push block and the guide block, so that an elastic linkage occurs between the two, and the second elastic member provides a force to move toward the fixed plate, so that in the initial state, the push block and the guide block move toward one side of the fixed plate, and only when the second arc surface cooperates with the guide block, will it drive the push block and the guide block to move toward one side of the first accommodating cavity, forming a clamping effect of the base, and a buffering effect will be formed during the cooperation between the fixed plate and the guide block, so as to avoid the push block from acting on the outer wall of the base and causing damage to the base. Moreover, the slide groove forms a guiding and limiting effect, and the push block and the guide block can only slide in the radial direction and cannot move in other directions. The push block and the guide block form a mutually restraining effect, thereby improving the stability of the connection. In addition, other elastic structures can also be used to cooperate to form a clamping and fixing effect.

[0030] 3. In the automatic assembly machine for solenoid valve plugs provided by the present invention, the cooperation between the bearing and the pin shaft makes the cooperation between the rotating shaft and the fixed plate smoother, thereby improving the sliding effect.

[0031] 4. The present invention provides an automatic assembly machine for solenoid valve plugs, in which there is no intersection between the first arc surface and the bearing, specifically, under the action of the second elastic member, the guide block is in the initial state, at which time the guide block will not intersect with the first arc surface, so that when the turntable rotates, the first arc surface will not drive the guide block to move, achieving a better matching effect. In addition, since the guide block and the push block are elastically connected, even if the first arc surface drives the guide block to move, as long as the elastic resistance between the guide block and the push block is guaranteed, the first arc surface will not drive the push block to move, but this structure requires precise control.

[0032] 5. The present invention provides an automatic assembly machine for solenoid valve plugs. Since the pins are arranged in a close-fitting manner, the pins need to be separated first during the clamping process. The pins are moved to the concave cavity and then the fixed block is moved upward in the vertical direction to achieve azimuthal offset, thereby achieving a separation effect and facilitating subsequent clamping operations.

[0033] 6. The present invention provides an automatic assembly machine for solenoid valve plugs, in which the third feeding mechanism forms a linear feeding effect, and the fourth feeding mechanism forms a reversing operation at the end of the feeding through the second arc groove, the second connecting plate, and the second guide shaft, so that the direction of the pins transported by the fourth feeding mechanism is different from that of the pins transported by the third feeding mechanism; this is equivalent to realizing feeding by forming the rotation direction of the pins through a driving device such as a rotating cylinder. This structure simply realizes the rotation effect, has simple parts, and reduces costs.

[0034] 7. In the automatic assembly machine for a solenoid valve plug provided by the present invention, the buffer forms a buffer limit effect, which better realizes the limit of the fourth clamping component and prevents excessive rotation.

[0035] 8. The present invention provides an automatic assembly machine for solenoid valve plugs. Since the first protrusion and the second protrusion are both arranged on the plug pin, the first protrusion and the second protrusion are electrically connected. Two spring pins are respectively abutted against the first protrusion and the second protrusion to ensure that the plug pin is installed and in place. If there is no plug pin installed at this position, an alarm will be triggered; or if one of the plug pins is not installed in place and the other three plug pins cannot contact the spring pin, an alarm will also be triggered. Compared with CCD detection, CCD detection can only perform overhead projection, and its projection detection cannot detect whether the plug pin is inserted in place. This mechanism combines mechanics and electricity to make the detection more accurate and improve assembly efficiency.

[0036] 9. The present invention provides an automatic assembly machine for electromagnetic valve plugs, which realizes the closing effect of qualified channels and unqualified channels by rotating the baffle plate, so that the installed electromagnetic valve plugs enter different collection areas.

[0037] 10. The present invention provides an automatic assembly machine for solenoid valve plugs, in which the cooperation between the dovetail portion and the dovetail groove forms a locking effect of the second crimping block in the Z-axis direction, and then the second crimping block and the second crimping seat are further connected and fixed by screws.

[0038] 11. In the automatic assembly machine for a solenoid valve plug provided by the present invention, the second notch and the second stepped groove form a giving way effect to prevent the first protrusion and the second protrusion from breaking during the crimping process.

[0059] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0060] Example 1

[0061] This embodiment provides an automatic assembly machine for a solenoid valve plug, as shown in the attached Figure 1-Figure 14 As shown, including:

[0062] The workbench 100 is placed on a horizontal plane as a whole.

[0063] The turntable 11 is located above the top surface of the workbench 100. The turntable 11 rotates relative to the workbench 100. Specifically, the workbench 100 is fixed here, and the turntable 11 rotates. The turntable 11 can form a rotation effect through a motor or a cylinder or an oil cylinder or other driving device. The turntable 11 is fixed with a plurality of clamp bodies 12 distributed in a circular array. The number of the clamp bodies 12 here can be adjusted according to actual needs. The clamp body 12 is provided with a first accommodating cavity 121, and the first accommodating cavity 121 is open upward. The first accommodating cavity 121 is used to fix the solenoid valve plug to form a accommodating and fixing effect. The outer wall of the clamp body 12 facing the center side of the turntable 11 is provided with a first through hole 122, and the first through hole 122 is connected to the first accommodating cavity 121.

[0064] The fixing plate 13 is located above the top surface of the turntable 11. The fixing plate 13 is connected and fixed to the workbench 100, forming an effect that the turntable 11 rotates relative to the fixing plate 13 and the workbench 100. The fixing plate 13 is provided with a first arc surface 131 and a second arc surface 132. The first arc surface 131 and the second arc surface 132 are arranged on the outer wall of the fixing plate 13. The diameter of the first arc surface 131 is smaller than the diameter of the second arc surface 132. At this time, the cross section of the fixing plate 13 is not a standard circle, but a special-shaped structure. The outer wall of the fixing plate 13 also includes two connecting surfaces 133. The two ends of the connecting surface 133 are respectively connected to the first arc surface 131 and the second arc surface 132, so that the entire outer wall is connected end to end to form a ring structure.

[0065] The elastic clamping mechanism includes a push block 14 and a guide block 15. The push block 14 is accommodated in the first through hole 122. The guide block 15 cooperates with the push block 14. When the second arc surface 132 abuts against the guide block 15, the guide block 15 drives the push block 14 to pass through the first through hole 122 and move toward the first accommodating cavity 121. When the second arc surface 132 is released from abutting against the guide block 15, the push block 14 moves toward the side away from the first accommodating cavity 121; the first arc surface 131 cannot drive the push block 14 to move toward the first accommodating cavity 121. In simple terms, when the second arc surface 132 cooperates with the guide block 15, the effect of the push block 14 moving with the first accommodating cavity 121 is formed, that is, a clamping and fixing effect is formed; when the first arc surface 131 cooperates with the guide block 15, the first arc surface 131 cannot push the push block 14 to move, and a loosening effect is formed at this time.

[0066] The first feeding mechanism 16 transports the gasket 101 into the first accommodating cavity 121, where the gasket 101 can be fed in an array by a vibration plate or other feeding methods, so that the first feeding mechanism 16 can place the gasket 101 into the first accommodating cavity 121 in a uniform direction.

[0067] The second feeding mechanism 17 transports the base 102 to the first accommodating cavity 121, where the base 102 can be fed in an array by a vibration plate or other feeding methods, so that the second feeding mechanism 17 can place the base 102 into the first accommodating cavity 121 in a uniform direction, where the base 102 is located above the gasket 101.

[0068] The first crimping mechanism 18 crimps the base 102 and the gasket 101. Specifically, the base 102 is provided with four fixing holes 1021, and the gasket 101 is provided with four fixing columns 1011 that match the fixing holes 1021. The fixing columns 1011 extend into the chamber 104 through the fixing holes 1021. Since the gasket 101 is made of silicone and has a certain elastic effect, the fixing columns 1011 and the fixing holes 1021 form an interference fit. Therefore, after crimping, the base 102 and the gasket 101 are firmly fixed.

[0069] The third feeding mechanism 19 matches one group of pins 103 with the base 102 in a first direction. The number of pins 103 in one group is two. The two pins 103 are symmetrically arranged on the base 102. The first direction is parallel to the long side wall of the base 102. The pins 103 can be fed in an array by a vibration plate or other feeding methods.

[0070] The fourth feeding mechanism 20, the fourth feeding mechanism 20 cooperates another group of pins 103 with the base 102 in the second direction, and the number of the other group of pins 103 is also two, and these two pins 103 are also symmetrically arranged on the base 102. Here, the second direction is a direction parallel to the short side wall of the base 102. The base 102 is an approximately rectangular parallelepiped structure, so the short side wall and the long side wall are vertically arranged, and the first direction and the second direction can also be vertically arranged, which is equivalent to four pins 103 fixed on the base 102, and the four pins 103 are distributed in the first accommodating cavity 121 in a circular array. It should also be noted here that the external connector can pass through the bottom surface of the first accommodating cavity 121 to connect with the pin 103. The top of the pin 103 can form an electrical connection effect for the wire. Here, the pin 103 can form an array feeding through a vibration plate or other feeding methods.

[0071] The second crimping mechanism 21 crimps the pin 103 and the base 102. The third feeding mechanism 19 and the fourth feeding mechanism 20 are a pre-installation operation. At this time, the pin 103 and the base 102 are not firmly fixed. At this time, the second crimping mechanism 21 forms a crimp between the pin 103 and the base 102, so that the four pins 103 are firmly fixed to the base 102.

[0072] The unloading mechanism 22 takes out the assembled solenoid valve plug from the first accommodating chamber 121. The unloading mechanism 22 is a material taking operation. After the solenoid valve plug is taken out, the fixture body 12 can be reused to form a circulation effect.

[0073] When the turntable 11 rotates to cooperate with the third feeding mechanism 19, the fourth feeding mechanism 20, and the second crimping mechanism 21, the second arc surface 132 abuts against the guide block 15; when the turntable 11 rotates to cooperate with the first feeding mechanism 16, the second feeding mechanism 17, and the unloading mechanism 22, the first arc surface 131 cooperates with the guide block 15. Simply put, during the feeding process of the base 102 and the gasket 101, the first accommodating cavity 121 is in a normal state (loose effect), and the corresponding parts can be easily placed. When the pin 103 is loaded and crimped for the second time, the first accommodating cavity 121 is in a clamping state (the push block 14 moves toward the first accommodating cavity 121, and the push block 14 abuts against the outer wall of the base 102). When the overall assembly is completed, the first accommodating cavity 121 returns to the normal state (loose effect) to facilitate the unloading operation. By rotating the turntable 11, the gasket 101 and the base 102 are fixed by the clamp body 12, and then the pin 103 is installed on the base 102, so as to realize the automatic assembly of the solenoid valve plug; secondly, through the special-shaped setting of the fixing plate 13, the turntable 11 can achieve different effects at different workstations during the rotation process. Since the environment at different positions is different during the installation process, for example, during the assembly process of the gasket 101 and the base 102, since the size of the first accommodating cavity 121 is adapted to it (with a certain margin, the base 102 can slide slightly when it is located in the first accommodating cavity 121), there is no need to clamp it, and a loose environment is required for easy installation. When fixing the pin 103, higher precision is required. In order to prevent the base 102 from deviating in the first accommodating cavity 121, the second arc surface 132 is connected with the guide block 15 and the push block 1 4, by moving the push block 14 toward the side of the first accommodating chamber 121, the push block 14 is against the outer wall of the base 102, forming a clamping and fixing effect, so that the base 102 is firmly fixed and will not shake, which is convenient for subsequent assembly operations. Compared with the cylinder or oil cylinder clamping structure, this structure can achieve the clamping and fixing effect only by the rotational force of the turntable 11, without the need for a cylinder or an oil cylinder, that is, through simple mechanical cooperation, the clamping and fixing effect of the base 102 can be achieved, which can greatly reduce the processing cost of the equipment, and can also release a lot of space for the installation of other automated structures; when located at the unloading mechanism 22, if the base 102 is still firmly clamped at this time, the unloading mechanism 22 cannot realize unloading, so at this time, the push block 14 is reversely moved, the base 102 is in a loose state, and the unloading mechanism 22 can easily complete the clamping and unloading.

[0074] Specifically, as attached Figure 1-Figure 11As shown, the clamp body 12 is provided with a second accommodating cavity 123, and the second accommodating cavity 123 is located outside the first accommodating cavity 121, and the two are connected through the first through hole 122. In this embodiment, the second accommodating cavity 123 is located on the side close to the center of the turntable 11. The clamp body 12 is provided with two legs 124 on the side facing the center of the turntable 11, and the legs 124 cooperate with the outer side wall of the first accommodating cavity 121 to form a transverse U-shaped structure, and the U-shaped structure is the second accommodating cavity 123. The second accommodating cavity 123 opens toward the center of the turntable 11. The side wall of the second accommodating cavity 123 is provided with a slide groove 125, and the slide groove 125 is arranged on the inner side wall of the two legs 124. The push block 14 and the guide block 15 are accommodated in the second accommodating cavity 123, and the push block 14 and the guide block 15 slide along the slide groove 125, where the push block 14 is located on the side close to the first accommodating cavity 121, and the guide block 15 is located on the side away from the first accommodating cavity 121. In this embodiment, the direction of the central axis of the turntable 11 is the Z-axis direction. The push block 14 and the guide block 15 slide along the radial direction of the turntable 11. One of the push block 14 and the guide block 15 is provided with a first hooking portion 141, and the other of the push block 14 and the guide block 15 is provided with a second hooking portion 151 that cooperates with the first hooking portion 141. A first elastic member 23 is fixed between the push block 14 and the guide block 15. In this embodiment, the first hooking portion 141 and the second hooking portion 151 are both L-shaped, and the two form a hooking fit, that is, one is a positive L-shape, and the other is an inverted L-shape, and the two lateral regions cooperate with each other. In this embodiment, the number of the first hooking portion 141 and the second hooking portion 151 are both two, two in a group, and are arranged on both sides, and the number of the first elastic member 23 here is also two. In this embodiment, the push block 14 is provided with a first hooking portion 141, the guide block 15 is provided with a second hooking portion 151, and the first elastic member 23 is located between the first hooking portion 141 and the guide block 15. When the guide block 15 moves toward the first accommodating cavity 121, the first hooking portion 141 and the second hooking portion 151 are separated, and the guide block 15 squeezes the first elastic member 23 so that the first elastic member 23 acts on the first hooking portion 141, so that the push block 14 moves toward the first accommodating cavity 121, which is equivalent to forming an elastic connection effect. On the contrary, when resetting, the first hooking portion 141 and the second hooking portion 151 are hooked, limiting the guide block 15 from moving toward the center of the turntable 11. A second elastic member 24 is fixed between the guide block 15 and the outer wall of the first accommodating cavity 121, and the second elastic member 24 here gives the guide block 15 a force to move toward the center of the turntable 11.The first hooking portion 141, the second hooking portion 151, and the first elastic member 23 form an elastic connection effect between the push block 14 and the guide block 15, so that elastic linkage occurs between the two, and the second elastic member 24 gives a force to move toward the fixed plate 13, so that in the initial state, the push block 14 and the guide block 15 move toward one side of the fixed plate 13, and only when the second arc surface 132 cooperates with the guide block 15, will the push block 14 and the guide block 15 be driven to move toward the first accommodating cavity 121, forming a clamping effect of the base 102, and the fixed plate 13 and the guide block 15 will form a buffering effect during the cooperation process to prevent the push block 14 from acting on the outer wall of the base 102 and causing damage to the base 102. Moreover, the slide groove 125 forms a guiding and limiting effect, the push block 14 and the guide block 15 can only slide along the radial direction of the turntable 11, and cannot move in other directions. The push block 14 and the guide block 15 form a mutually restraining effect, which improves the stability of the connection, and the push block 14 and the guide block 15 will not fall off and separate. After the guide block 15 is squeezed, a reset effect is formed through the first elastic member 23 and the second elastic member 24. In addition, other elastic structures can also be used to form a clamping and fixing effect.

[0075] Specifically, as attached Figure 2-Figure 11 As shown, the guide block 15 is provided with three grooves, the middle groove is used to accommodate the second elastic member 24, that is, the second elastic member 24 is partially accommodated in the middle groove, and the rest of the second elastic member 24 extends to the outside and abuts against the outer wall of the first accommodating chamber 121. The grooves located on both sides are used to accommodate the first elastic member 23, the first elastic member 23 is partially accommodated in the outer groove, and the rest of the first elastic member 23 extends to the outside and abuts against the first hooking portion 141. Here, the outer wall of the first accommodating chamber 121 and the first hooking portion 141 can be provided with grooves or positioning columns that cooperate with the spring to form a fixing effect of the spring. In addition, the guide block 15 can also be provided with a positioning column, so that the spring is sleeved on the positioning column to form a positioning and fixing effect, or the positioning column and the groove can cooperate to form a positioning and fixing of the spring. In this embodiment, the first elastic member 23 and the second elastic member 24 are both springs.

[0076] Specifically, as attached Figure 2-Figure 11As shown, the elastic clamping mechanism also includes a pin 25 and a bearing 26. One end of the pin 25 is connected and fixed to the guide block 15, and the other end of the pin 25 is connected to the bearing 26. The bearing 26 cooperates with the second arc surface 132. The cooperation between the bearing 26 and the pin 25 makes the cooperation between the rotating shaft and the fixed plate 13 smoother, thereby improving the sliding effect. When the turntable 11 rotates and the second arc surface 132 abuts against the bearing 26, the second arc surface 132 will drive the bearing 26 to slide along the radial direction of the turntable 11, so that the guide block 15 and the push block 14 slide toward the side of the first accommodating cavity 121, forming an elastic clamping effect, so that the base 102 fixed in the first accommodating cavity 121 is clamped and fixed.

[0077] Specifically, as attached Figure 2-Figure 11 As shown, the motion trajectory of the bearing 26 has no intersection with the first arc surface 131. There is no intersection between the first arc surface 131 and the bearing 26, which specifically means that under the action of the second elastic member 24, the guide block 15 is in the initial state. At this time, the guide block 15 will not intersect with the first arc surface 131, so that when the turntable 11 rotates, the first arc surface 131 will not drive the guide block 15 to move, achieving a better matching effect. In addition, since the guide block 15 and the push block 14 are elastically connected, even if the first arc surface 131 drives the guide block 15 to move, as long as the elastic resistance between the guide block 15 and the push block 14 is guaranteed, it can be achieved that the first arc surface 131 will not drive the push block 14 to move, but this structure requires precise control.

[0078] Specifically, a second through hole is provided in the middle of the turntable 11, and the fixing plate 13 is located above the second through hole. Bolts pass through the fixing plate 13 and the second through hole to connect and fix with the workbench 100, thereby realizing the connection and fixation of the fixing plate 13 and the workbench 100. At this time, the turntable 11 can rotate relative to the workbench 100, while the fixing plate 13 is fixed. Here, the size of the fixing plate 13 is larger than the size of the second through hole.

[0079] Specifically, as attached Figure 2-Figure 6 , Fig.13As shown, it also includes a pin feeding guide rail 27 and a pin distribution device 28. A plurality of pins 103 distributed in an array are fixed on the pin feeding guide rail 27. In this embodiment, two rows of pins 103 are fixed on the pin feeding guide rail 27, and the two rows of pins 103 are symmetrically arranged. The initial end of the pin feeding guide rail 27 is connected to a vibration plate or other feeding equipment to form an effect of transporting the pins 103. In this embodiment, the movement direction of the pin feeding guide rail 27 is also along the radial direction of the turntable 11. The sub-pin device 28 is located at the end of the pin feeding guide 27. The sub-pin device 28 includes a fixed block 281 and a sub-pin driving source 282. The fixed block 281 is provided with a concave cavity 283 on the side facing the pin feeding guide 27. The pin 103 moves to the concave cavity 283, and the sub-pin driving source 282 drives the fixed block 281 to move vertically upward. Vertically upward specifically refers to along the Z-axis direction, forming an upper and lower misalignment with the pin feeding guide 27, so that the clamping assembly can form a clamping effect. The depth of the concave cavity 283 here is adapted to the thickness of a pin 103, that is, the concave cavity 283 can only accommodate one pin 103. The number of the pin feeding guide 27 and the sub-pin device 28 are both two, two in a group, and are respectively arranged in the third feeding mechanism 19 and the fourth feeding mechanism 20. Since the pins 103 are arranged in a close fit, the pins 103 cannot be clamped directly during the clamping process. The pins 103 need to be separated first, by moving the pins 103 to the concave cavity 283, and then moving the fixed block 281 upward in the vertical direction to achieve the azimuth offset, thereby achieving the separation effect and facilitating the subsequent clamping operation. In addition, compared with the pin blocking isolation, this pin separation device 28 has higher accuracy and is less likely to be confused.

[0080] Specifically, as attached Figure 2-Figure 6As shown, the third feeding mechanism 19 includes a first guide plate 192 and a first guide shaft 193. The first guide plate 192 is provided with a first straight groove 194. Here, the first straight groove 194 is also provided along the radial direction of the rotating disk 11. The first guide shaft 193 is located in the first straight groove 194 and slides. Here, the first guide shaft 193 is provided on the third clamping assembly 191 to form a motion guiding effect of the third clamping assembly 191 to prevent its position from being offset. The fourth feeding mechanism 20 includes a second guide plate 202, a second guide shaft 203 and a second connecting plate 204. The second guide shaft 203 is rotatably connected to the second connecting plate 204. The other end of the second connecting plate 204 is connected to the fourth clamping assembly 201. The second guide plate 202 is provided with a second arc groove 205. The second guide shaft 203 is located in the second arc groove 205 and slides. When the fourth clamping assembly 201 slides, it slides along the second arc groove 205, and the second connecting plate 204 rotates to form a change in direction. The third feeding mechanism 19 forms a linear feeding effect, and the fourth feeding mechanism 20 forms a reversing operation at the end of the feeding through the second arc groove 205, the second connecting plate 204, and the second guide shaft 203, so that the direction of the pin 103 transported by the fourth feeding mechanism 20 is different from that of the pin 103 transported by the third feeding mechanism 19; this is equivalent to forming the rotation direction of the pin 103 through a driving device such as a rotating cylinder to realize feeding. This structure simply realizes the rotation effect, has simple parts, and reduces costs.

[0081] Specifically, as attached Figure 2-Figure 6 As shown, the fourth feeding mechanism 20 also includes a buffer 206 and a fourth clamping assembly 201, and the buffer 206 is located on the motion trajectory of the fourth clamping assembly 201. The buffer 206 forms a buffer limit effect, which better realizes the limit of the fourth clamping assembly 201 and prevents excessive rotation. Here, the buffer 206 is located at the limit position when the fourth clamping assembly 201 rotates to a certain angle. When the fourth clamping assembly 201 abuts against the buffer 206, the fourth clamping assembly 201 moves downward along the Z-axis direction to form a placement and fixation of the pin 103.

[0082] Specifically, it also includes a detection mechanism 29, which is provided with a spring pin 291 that cooperates with the plug pin 103. The plug pin 103 is provided with a first protrusion 1031 and a second protrusion 1032. One of the spring pins 291 abuts against the first protrusion 1031, and one of the spring pins 291 abuts against the second protrusion 1032. The detection mechanism 29 determines whether there is conduction between the two spring pins 291. Since the first protrusion 1031 and the second protrusion 1032 are both provided on the plug pin 103, the first protrusion 1031 and the second protrusion 1032 are electrically connected. The two spring pins 291 abut against the first protrusion 1031 and the second protrusion 1032 respectively to ensure that the plug pin 103 is installed and the plug pin 103 is installed in place. If the plug pin 103 is not installed in this position, an alarm will be generated; or if one of the plug pins 103 is not installed in place, the other three plug pins 103 cannot contact the spring pin 291, and an alarm will also be generated. Compared with CCD detection, CCD detection can only perform top-down projection, and its projection detection cannot detect whether the pin 103 is inserted in place. This mechanism combines mechanics and electricity to make the detection more accurate and improve assembly efficiency.

[0083] Specifically, as attached Figure 2-Figure 6 As shown, the unloading mechanism 22 includes a qualified channel 221, an unqualified channel 222 and a material dividing assembly, wherein the upper end of the qualified channel 221 is connected to the upper end of the unqualified channel 222; the material dividing assembly includes a material dividing driving source 223 and a baffle 224, wherein one end of the baffle 224 is rotatably connected to the connection between the qualified channel 221 and the unqualified channel 222, and the material dividing driving source 223 is connected to the other end of the baffle 224, and the baffle 224 is driven to close the qualified channel 221 or the unqualified channel 222. The closing effect of the qualified channel 221 and the unqualified channel 222 is achieved by rotating the baffle 224, so that the installed solenoid valve plug enters different collection areas. In this embodiment, the qualified channel 221 and the unqualified channel 222 form an inverted Y-shaped structure, and the baffle 224 is located at the connection.

[0084] Specifically, as attached Fig.14As shown, the second crimping mechanism 21 includes a second crimping seat 211 and a plurality of second crimping blocks 212. The second crimping seat 211 is provided with a dovetail groove 2111. A dovetail portion 2121 is provided at the top of the second crimping block 212. The dovetail portion 2121 cooperates with the dovetail groove 2111. The screws pass through the second crimping seat 211 and the second crimping block 212 to connect and fix. The cooperation between the dovetail portion 2121 and the dovetail groove 2111 forms a locking effect of the second crimping block 212 in the Z-axis direction. Then, the connection and fixation between the second crimping block 212 and the second crimping seat 211 are further realized by screws. In this embodiment, two dovetail grooves 2111 are provided on the second crimping seat 211. The two dovetail grooves 2111 are vertically connected to each other. The number of the second crimping blocks 212 is four, and two groups of two cooperate with the corresponding dovetail grooves 2111.

[0085] Specifically, as attached Fig.14 As shown, the second crimping block 212 has a second notch 2122 and a second stepped groove 2123 at the lower end, the second notch 2122 cooperates with the first protrusion 1031, and the second stepped groove 2123 cooperates with the second protrusion 1032. In the automatic assembly machine for a solenoid valve plug provided by the present invention, the second notch 2122 and the second stepped groove 2123 form a giving way effect, thereby preventing the first protrusion 1031 and the second protrusion 1032 from breaking during the crimping process.

[0086] Specifically, the first feeding mechanism 16 also includes a first clamping assembly 161, which can move up and down along the Z-axis direction under the action of the driving source, or can move along the radial direction of the turntable 11 (driven by a motor or cylinder or other driving device). The first clamping assembly 161 is also provided with a first clamping head, which can be clamped or opened. In this embodiment, the gasket 101 is transported to the end of the feeding guide rail of the gasket 101, the first clamping assembly 161 moves above it, then clamps the first clamping head, moves downward along the Z-axis direction until it moves to abut against the gasket 101, and then opens the first clamping head to achieve the clamping of the gasket 101. After completing the clamping of the gasket 101, the first clamping assembly 161 first moves upward along the Z-axis direction, continues to move along the radial direction of the turntable 11 to the top of the corresponding fixture body 12, and then moves downward along the Z-axis direction, so that the gasket 101 is accommodated in the first accommodating cavity 121, forming the clamping and placement of the gasket 101. It should also be noted here that the first feeding mechanism 16 also includes a detection probe to detect the position and state of the gasket 101.

[0087] Specifically, the second feeding mechanism 17 also includes a second clamping assembly 171, which can move up and down along the Z-axis direction under the action of the driving source, or can move along the radial direction of the turntable 11 (driven by a motor or cylinder or other driving device).

In this embodiment, the base 102 is transported to the end of the feeding guide rail of the base 102, the second clamping assembly 171 moves above it, then clamps the second clamping head, moves downward along the Z-axis direction until it moves to abut against the base 102, and then opens the second clamping head to achieve the clamping of the base 102. After completing the clamping of the base 102, the second clamping assembly 171 moves upward along the Z-axis direction, continues to move along the radial direction of the turntable 11 to the top of the corresponding fixture body 12, and then moves downward along the Z-axis direction, so that the base 102 is accommodated in the first accommodating cavity 121, and at this time, the base 102 is located above the gasket 101. It should also be noted that the second feeding mechanism 17 includes a detection probe to detect the position and state of the base 102 .

[0088] Specifically, the first crimping mechanism 18 includes a first crimping block 181, which moves up and down along the Z axis. When the fixture body 12 equipped with the base 102 and the gasket 101 moves to the bottom of the first crimping block 181, the first crimping block 181 moves downward, so that the base 102 is connected and fixed with the gasket 101. The push block 14 and the guide block 15 of this station do not move and are in the initial state, and the base 102 is not clamped and fixed.

[0089] Specifically, the third feeding mechanism 19 includes a third clamping assembly 191, which can move up and down along the Z-axis direction under the action of a driving source, or can move along the radial direction of the turntable 11 (driven by a motor or cylinder or other driving device). The third clamping assembly 191 is also provided with a third clamping head, which can be clamped or opened. In this embodiment, the pin 103 is transported to the end of the pin feeding guide rail 27, and the pin 103 moves upward along the Z-axis through the movement of the corresponding fixed block 281. At this time, the third clamping assembly 191 moves above it, and then opens the third clamping head and moves downward along the Z-axis direction until it moves to abut against the pin 103, and then clamps the third clamping head to achieve the clamping of the pin 103. After completing the clamping of the pin 103, the third clamping assembly 191 moves upward along the Z-axis direction, continues to move along the radial direction of the turntable 11 to the top of the corresponding fixture body 12, and then moves downward along the Z-axis direction, so that the pin 103 cooperates with the base 102 to form a pre-installed effect. It should also be noted here that the third feeding mechanism 19 includes a detection probe to detect the position and state of the pin 103. The push block 14 corresponding to this station moves toward the first accommodating cavity 121 under the action of the second arc surface 132, forming a clamping effect with the base 102.

[0090] Specifically, the fourth feeding mechanism 20 includes a fourth clamping assembly 201. Here, the third feeding mechanism 19 and the fourth feeding mechanism 20 have similar structures, and the difference is that the fourth clamping assembly 201 is rotated 90° before installing the pin 103 (a mechanical turn is formed by the second arc groove 205, the second connecting plate 204, and the second guide shaft 203). The push block 14 corresponding to this station moves toward the first accommodating cavity 121 under the action of the second arc surface 132, forming a clamping effect with the base 102.

[0091] Specifically, the second crimping mechanism 21 can move along the Z-axis under the action of the driving source. The push block 14 corresponding to this station moves toward the first accommodating cavity 121 under the action of the second arc surface 132 to form a clamping effect with the base 102 .

[0092] Specifically, the detection mechanism 29 can move along the Z-axis under the action of the driving source. The push block 14 corresponding to this station moves toward the first accommodating cavity 121 under the action of the second arc surface 132 to form a clamping effect with the base 102 .

[0093] Specifically, the unloading mechanism 22 includes a fifth clamping assembly 225, which can move up and down along the Z-axis direction or move along the radial direction of the turntable 11 under the action of the driving source. The fifth clamping assembly 225 includes a fifth clamping head, which can be clamped or opened. The push block 14 and the guide block 15 of this station do not move and are in the initial state, and the base 102 is not clamped and fixed. When the assembled solenoid valve plug moves to the position of the unloading mechanism 22, the fifth clamping head is first clamped, then moves downward along the Z-axis to the chamber 104 of the base 102, and then opens to form a clamping fixation. The clamped fifth clamping assembly 225 moves along the radial direction of the turntable 11 until it moves to the top of the qualified channel 221 and the unqualified channel 222, and performs the unloading operation. The baffle 224 is controlled by the control mechanism to achieve the separation of qualified and unqualified products.

[0094] Specifically, the first crimping mechanism 18, the third feeding mechanism 19, the fourth feeding mechanism 20, the second crimping mechanism 21, the detection mechanism 29 and the unloading mechanism 22 are all arranged on the top surface of the workbench 100, and are all located outside the outer wall of the turntable 11, forming a circumferential distribution. The first feeding mechanism 16 and the second feeding mechanism 17 are arranged on a horizontal plane, and their upper ends extend to the top surface of the workbench 100 along the radial direction of the turntable 11.

[0095] Specifically, the driving source in this embodiment can be a pneumatic cylinder, an oil cylinder, a motor, or other driving devices.

[0096] Specifically, it also includes a control mechanism, which controls the actions of each mechanism. The control mechanism here can be PLC control.

[0097] Specifically, it also includes an alarm mechanism. When a fault occurs, the alarm mechanism will give an alarm. The alarm method here can be one of light and sound, or a combination of the two.

[0098] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
