Referring to fig. 9 to 12, in the present embodiment, the material control mechanism 23 includes a stopper 232, a pressing block 233, a holder 234, a lock block 237, a reset member 238, an ejector 235, a thrust member 236, and a U-shaped material control rack 231; one end of the control material rack 231 is connected with the moving track 22, so that the bushing 200 in the moving track 22 automatically slides into the control material rack 231; an ejection hole 2311 is formed in the inner bottom of the material control frame 231 in a penetrating manner, and a thrust hole 2312 is formed in the side wall of the material control frame 231 in a penetrating manner; the stop block 232 is arranged at the other end of the material control frame 231, and the stop block 232 is used for limiting the bushing 200 to slide continuously when the bushing 200 moves to the position right above the ejection hole 2311; the number of the retainers 234 is two, the two retainers 234 are arranged at the upper end of the material control rack 231 at intervals, and a limit area for adapting to the lifting of the bushing 200 is formed between the two retainers 234; the locking block 237 is horizontally and slidably arranged at the inner bottom of the retainer 234, one end of the locking block 237, which is close to the limiting area, is provided with a guide inclined surface 2371, and one end of the locking block 237, which is far away from the limiting area, is connected with the retainer 234 through a reset piece 238; the ejection member 235 is slidably disposed in the ejection hole 2311 up and down, when the ejection member 235 slides up, the ejection member 235 pushes up one of the bushings 200 directly above the ejection hole 2311, so that the guiding inclined surface 2371 is pressed by the bushing 200 to force the locking block 237 to slide outwards, until the bushing 200 moves above the locking block 237, the reset member 238 forces the locking block 237 to slide inwards, and thus the bushing 200 is supported in the limiting area; the thrust piece 236 is slidably disposed in the thrust hole 2312, and when the thrust piece 236 slides into the control rack 231, the thrust piece 236 is used for limiting the bushing 200 directly above the ejection hole 2311 from being extruded by other bushings 200; the pressing block 233 is provided at an upper end of the control stack 231, and the pressing block 233 serves to restrict the bushing 200, which is not directly above the ejection hole 2311, from being upwardly separated from the control stack 231. During the material control operation, under the action of the vibration plate 21, the bushing 200 in the moving rail 22 gradually moves to the inside of the material control frame 231 until being blocked by the stop block 232, as shown in fig. 11, at this time, the ejection member 235 is controlled to move upwards, so that one bushing 200 right above the ejection hole 2311 can be ejected upwards; during ejection, the bushing 200 generates a pushing force to the guiding inclined plane 2371, and the horizontal component force of the pushing force pushes the locking block 237 to slide outwards (i.e. in the left direction in fig. 11), after the bushing 200 moves normally above the locking block 237 (i.e. in the limit area), the ejector 235 is controlled to move downwards, and the locking block 237 automatically slides inwards under the elastic force of the reset element 238, so as to prevent the bushing 200 in the limit area from falling; when the ejector 235 is reset downwards, the bushings 200 in the moving rail 22 move towards the direction of the material control rack 231 by one unit length, so that the next bushing 200 moves right above the ejection holes 2311 again, and then the ejector 235 is repeatedly operated to eject the corresponding bushing 200 upwards into the limit area, so that a proper number of bushings 200 can be stacked in the limit area by repeatedly operating the ejector 235. In addition, as shown in fig. 12, during the ejection of the ejector 235, the thrust piece 236 slides into the control rack 231, so as to abut against the subsequent bush 200 (i.e., the bush 200 not located directly above the ejection hole 2311) to prevent the subsequent bush 200 from pressing the bush 200 directly above the ejection hole 2311; after the ejector 235 is reset downward, the thrust piece 236 slides to the outside of the control rack 231, so that the subsequent bushing 200 continues to slide. In addition, as shown in fig. 11, during the ejection of the ejection member 235, the pressing block 233 presses the bushings 200 that are not directly above the ejection holes 2311 in the control rack 231, thereby preventing the bushings 200 from being accidentally ejected, and ensuring the reliability of continuous operation. The manner in which the up and down movement of the ejector 235 and the horizontal movement of the thrust member 236 are controlled is known in the art, for example, by a direct drive of a cylinder. The return member 238 is also known in the art, such as a spring.

Feeding mechanism

Referring to fig. 3, 7, 13 and 14, the feeding mechanism 24 includes a feeding robot 241, a feeding frame 242, a feeding rod 243, a guide rod 244, a pressing block 245, an elastic member 246, a feeding clamp 247 and a feeding clamping cylinder 248, and the feeding robot 241 is used for driving the feeding frame 242 to move in a three-dimensional space; the upper ends of the material inserting rod 243 and the guide rod 244 are arranged on the feeding frame 242, the material pressing block 245 is connected with the material inserting rod 243 and the guide rod 244 in a vertical sliding way, and the lower end of the material pressing block 245 is provided with a material pressing part 2451 in a protruding way; the elastic piece 246 is disposed between the presser 245 and the feeding frame 242, and the elastic piece 246 is used for forcing the presser 245 to slide downwards; the number of the feeding clamps 247 is two, one ends of the two feeding clamps 247 are arranged on the feeding clamping air cylinders 248, and the feeding clamping air cylinders 248 are arranged on the feeding frame 242; when the insert rod 243 moves to the position right above the limit area and is downwardly inserted into the bushing 200 in the limit area, the other ends of the two feed clamps 247 are respectively clamped on the corresponding bushing 200 through the gap between the two holders 234, at this time, the bushing 200 flush with the feed clamps 247 and the bushing 200 above the feed clamps 247 are separated from the limit area upward along with the insert rod 243, and the gap between the two feed clamps 247 is greater than or equal to the width of the pressing part 2451. During the material taking operation, the feeding robot 241 drives the feeding frame 242 to move, so that the lower end of the material inserting rod 243 is inserted into each lining 200 in the limiting area from the right upper side of the limiting area (i.e. the uppermost lining 200 in fig. 9) downwards; in the process, the uppermost bushing 200 forces the plunger 245 to slide up the guide rod 244 and compresses the elastic member 246; then, the two feed clamps 247 are driven to clamp each other by the feed clamping cylinder 248, the two feed clamps 247 are clamped on the lowest one of the bushings 200 in the limit area by the gap between the two holders 234, the feeding robot 241 drives the feeding frame 242 to move upward, so that each bushing 200 in the limit area can be simultaneously taken out, and the taken out bushings 200 can continue to move by the feeding frame 242. It should be noted that, as shown in fig. 3, in order to save cost and improve space utilization, the feeding mechanism 24 may take a plurality of bushings 200 at a time for standby (i.e. the feeding robot 241 does not need to perform frequent reciprocating motion to perform material taking), so the feeding robot 241 may share the same four-axis robot with the material taking robot 141.

Device to be assembled

Referring to fig. 15, 17 and 18, in the present embodiment, in order to achieve positioning of the bush 200, the to-be-mounted device 3 includes a second positioning mechanism 34, and the second positioning mechanism 34 includes a rotary clamping cylinder 341, a rotary seat 342, a positioning rod 343, and two to-be-mounted clips 344; the rotary clamping cylinder 341 is arranged on the to-be-assembled table 32, and the rotary seat 342 and the two to-be-assembled clamps 344 are arranged on the rotary clamping cylinder 341; one end of the positioning rod 343 is disposed on the rotary base 342, and the other end of the positioning rod 343 is provided with a plugging portion 3431 for plugging the single bushing 200. In the initial state, the rotary clamping cylinder 341 drives the rotary seat 342 and the to-be-clamped 344 to rotate, so that the plug-in portion 3431 is rotated to be arranged toward the upper side; when the lower end of the rod 243 moves to align with the insertion portion 3431, the two feed clamps 247 are opened to each other, so that the bushings 200 on the rod 243 are integrally and downwardly displaced by one unit length under the action of the elastic members 246, and the lowest bushing 200 on the rod 243 is automatically placed on the insertion portion 3431; then, the two feeding clamps 247 re-clamp the corresponding bushings 200 on the inserting rod 243, and then control the inserting rod 243 to be far away from the inserting part 3431; next, the rotary clamping cylinder 341 drives the two clamps 344 to clamp each other until the two clamps 344 clamp the lower ends of the bushings 200 on the plug-in parts 3431, and the rotary clamping cylinder 341 drives the rotary seat 342 and the clamps 344 to rotate, so that the bushings 200 on the plug-in parts 3431 rotate to a horizontal state to complete positioning.

Referring to fig. 15, in the present embodiment, in order to reduce the waiting time of the transfer device 4, the device to be mounted 3 further includes a base 31; the number of the to-be-assembled tables 32 is two, the two to-be-assembled tables 32 are slidably arranged on the base 31, and one to-be-assembled table 32 is positioned above the other to-be-assembled table 32; the two to-be-assembled tables 32 are respectively provided with a first positioning mechanism 33 and a second positioning mechanism 34, the number of the first positioning mechanisms 33 and the number of the second positioning mechanisms 34 on the same to-be-assembled table 32 are equal to the number of molding cavities on the injection mold 500, and the positions of the first positioning mechanisms 33 and the positions of the second positioning mechanisms 34 on the same to-be-assembled table 32 are adapted to the positions of the molding cavities. That is, with the two stages 32 of the upper and lower layers being slidably staggered, no interference is generated, and when one of the stages 32 conveys the terminals 300 and the bushings 200 through the feeding mechanism 24, the other stage 32 has positioned a corresponding number of the terminals 300 through the first positioning mechanism 33, and has positioned a corresponding number of the bushings 200 through the second positioning mechanism 34, so that the transfer device 4 can clamp the bushings.

First clamping mechanism

Referring to fig. 19, in the present embodiment, the first gripping mechanism 42 includes a first mounting plate 421, a first gripping piece 422 for gripping the terminal 300, and a second gripping piece 423 for gripping the bush 200; the first mounting plate 421 is provided to the transfer robot 41, and the first gripping member 422 and the second gripping member 423 are provided to the first mounting plate 421.

First clamping piece

Referring to fig. 20 and 21, in the present embodiment, the first gripping member 422 includes a support base 4221, a first clamping cylinder 4222, and two first clamping arms 4223; the support base 4221 and the first clamping cylinder 4222 are both disposed on the first mounting plate 421, and two positioning portions 4224 for adapting to the front end of the terminal 300 are formed at one end of the support base 4221 away from the first mounting plate 421; one ends of the two first clamping arms 4223 are arranged on the first clamping cylinder 4222, and clamping parts 4227 extend oppositely at the other ends of the two first clamping arms 4223; when the positioning portion 4224 moves to contact with the front ends of the terminals 300 in the positioning groove 332, the first clamping cylinder 4222 drives the two first clamping arms 4223 to clamp each other, so that the two clamping portions 4227 move to the lower sides of the two terminals 300 respectively through the third groove 3323 on the positioning groove 332 (as shown in fig. 16), and further clamp the front ends of the terminals 300 between the clamping portions 4227 and the positioning portion 4224.

Referring to fig. 21 and 22, in the present embodiment, a ramp structure 4229 is provided between an end surface of the clamping portion 4227 away from the first clamping arm 4223 and a side surface of the clamping portion 4227 facing the terminal 300, and when the two clamping portions 4227 move toward each other under the action of the ramp structure 4229, the clamping portion 4227 can be prevented from scratching the terminal 300 and interfering with the terminal 300.

Referring to fig. 21, in the present embodiment, in order to improve the positioning accuracy between the positioning portion 4224 and the terminal 300 and the stability after positioning, the positioning portion 4224 is provided with a positioning post 4225 protruding from a hole site 302 (as shown in fig. 1) for adapting to the front end of the terminal 300, and the clamping portion 4227 is provided with a yielding groove 4228 for adapting to the positioning post 4225.

Referring to fig. 21, in the present embodiment, since the pin 301 at the front end of the terminal 300 needs to be inserted into the pin groove of the mold insert when the terminal 300 is assembled into the injection mold 500, in order to prevent deformation of the pin 301 during insertion, the positioning portion 4224 is provided with the arc surface structure 4226 for adapting to the outer arc surface between the front end of the terminal 300 and the pin 301, and the root of the pin 301 is supported by the arc surface structure 4226, thereby preventing deformation of the pin 301 during insertion.

Referring to fig. 19, in the present embodiment, since the insertion depth of the pin 301 into the pin slot is neither large nor small, it is difficult to precisely control the relative height between the positioning portion 4224 (i.e., the support base 4221) and the first mounting plate 421 during the actual mounting process, and therefore, the first gripping mechanism 42 further includes a lifting adjusting member 424, the support base 4221 is connected to the first mounting plate 421 through the lifting adjusting member 424, and the relative height between the positioning portion 4224 and the first mounting plate 421 is continuously adjusted through the lifting adjusting member 424, so that the relative height between the positioning portion 4224 and the first mounting plate 421 is suitable.

Lifting adjusting piece

Referring to fig. 21 and 23, in the present embodiment, the lifting adjuster 424 includes an upper housing 4241, a lower housing 4242, a guide post 4243, a guide sleeve 4244, two upper bolts 4245, and two lower bolts 4246; the supporting seat 4221 is disposed on the upper seat 4241, and the upper seat 4241 and the lower seat 4242 are respectively located on the upper and lower sides of the first mounting plate 421; the guide sleeve 4244 is disposed on the first mounting plate 421, and the guide sleeve 4244 penetrates through the upper and lower sides of the first mounting plate 421; the guide post 4243 is connected to the guide sleeve 4244 in a vertically sliding manner, the upper end of the guide post 4243 is connected with the upper base 4241, and the lower end of the guide post 4243 is connected with the lower base 4242; one upper bolt 4245 is in threaded connection with the upper base 4241, the other upper bolt 4245 is in threaded connection with the first mounting plate 421, and the two upper bolts 4245 are in mutual abutting connection; one lower bolt 4246 is screwed to the lower housing 4242, the other lower bolt 4246 is screwed to the first mounting plate 421, and the two lower bolts 4246 are abutted against each other. During debugging, the height between the upper base 4241 (i.e. the supporting base 4221) and the first mounting plate 421 is changed by rotating the two upper bolts 4245, after the position of the upper base 4241 is changed, the position of the lower base 4242 is correspondingly changed (i.e. when the distance between the upper base 4241 and the first mounting plate 421 is reduced, the distance between the lower base 4242 and the first mounting plate 421 is increased, otherwise, the distance is opposite), and the position of the lower base 4242 is adapted to the change of the position by rotating the two lower bolts 4246, so that the two upper bolts 4245 are always in contact with each other, and the two lower bolts 4246 are always in contact with each other, thereby maintaining the relative height between the upper base 4241 and the first mounting plate 421 unchanged. The use of two upper bolts 4245 and two lower bolts 4246 can prevent the upper bolts 4245 and the lower bolts 4246 from contacting the first mounting plate 421; the pitches of the two upper bolts 4245 may be different to achieve coarse adjustment by one upper bolt 4245 (i.e., having a larger pitch) and fine adjustment by the other upper bolt 4245 (i.e., having a smaller pitch); the pitch of the two lower bolts 4246 are different to achieve coarse adjustment by one lower bolt 4246 (i.e., the pitch is larger) and fine adjustment by the other lower bolt 4246 (i.e., the pitch is smaller).

Second clamping piece

Referring to fig. 19 and 24, in the present embodiment, the second gripping member 423 includes a second gripping cylinder 4231 and two second gripping arms 4232; the second clamping cylinder 4231 is slidably disposed on the first mounting plate 421 along the axial direction of the bushing 200, the lower ends of the two second clamping arms 4232 are disposed on the second clamping cylinder 4231, and the upper ends of the two second clamping arms 4232 are used for clamping or loosening the bushing 200. When the second clamping member 423 moves to the second positioning mechanism 34 (as shown in fig. 15 and 17), the second clamping cylinder 4231 drives the two second clamping arms 4232 to clamp the bushing 200, the rotating clamping cylinder 341 drives the two clamps 344 to release the bushing 200, and the second clamping cylinder 4231 slides along the axial direction of the bushing 200 in a direction away from the rotating seat 342, so that the bushing 200 can be taken out from the inserting portion 3431. Similarly, when the bush 200 is automatically assembled into the injection mold 500 by sliding the second clamp cylinder 4231 in the axial direction of the bush 200 at the position of the injection mold 500, the bush 200 is released by the second clamp cylinder 4231, and the second clamp cylinder is slid in the opposite direction, thereby completing the automatic assembly of the bush 200. The sliding mounting manner of the second clamping cylinder 4231 on the first mounting plate 421 is in the prior art, for example, sliding limiting is realized through a sliding groove sliding block, and power required by sliding is provided through the cylinder.

Referring to fig. 25, in the present embodiment, the upper end of the second clamp arm 4232 is provided with a profiling groove 4233 for fitting the bush 200, so that radial displacement of the bush 200 between the two second clamp arms 4232 can be restricted by the profiling groove 4233. In addition, one end of the profiling groove 4233 is provided with a thrust step 4234, and by setting the direction in which the bush 200 is assembled into the injection mold 500 to be the opposite direction of the thrust step 4234 (i.e., the direction along the profiling groove 4233 axially away from the thrust step 4234), the thrust step 4234 axially limits the bush 200 during assembly, thereby improving the assembly accuracy between the bush 200 and the injection mold 500.

Second clamping mechanism

Referring to fig. 26 and 27, in the present embodiment, the second gripping mechanism 43 includes a second mounting plate 431, a third gripping cylinder 432, and two third gripping arms 433; the second mounting plate 431 is disposed on the transfer robot 41, and the second mounting plate 431 is not located on the same side as the first mounting plate 421; the third clamping cylinder 432 is disposed on the second mounting plate 431, one ends of the two third clamping arms 433 are disposed on the third clamping cylinder 432, and the other ends of the two third clamping arms 433 are adapted to clamp or unclamp the housing 100. That is, when the housing 100 (i.e., the automobile sensor) needs to be taken out of the injection mold 500, only the first mounting plate 421 and the second mounting plate 431 need to be driven to rotate by the transfer robot 41 so that the second mounting plate 431 faces the injection mold 500, and the two third clamping arms 433 can be driven to clamp the housing 100 by the third clamping cylinder 432, so that the housing 100 can be taken out. Similarly, when the terminals 300 and the bushings 200 are required to be assembled into the injection mold 500, the first mounting plate 421 and the second mounting plate 431 only need to be driven to rotate by the transfer robot 41 so that the first mounting plate 421 faces the injection mold 500.

Referring to fig. 27, in this embodiment, in order to avoid pinching the housing 100, the second pinching mechanism 43 further includes two cushions 434, and the two cushions 434 are disposed opposite to the two third pinching arms 433, so as to avoid the third pinching arms 433 from directly contacting the housing 100..

Referring to fig. 19 and 26, in the present embodiment, the number of the first clamping mechanisms 42 and the number of the second clamping mechanisms 43 are equal to the number of molding cavities on the injection mold 500, and the positions of the first clamping mechanisms 42 and the positions of the second clamping mechanisms 43 are adapted to the positions of the molding cavities on the injection mold 500, so that the terminals 300 and the bushings 200 required for the same injection molding are clamped at one time by the respective first clamping mechanisms 42, and the plurality of housings 100 for the same injection molding are clamped at one time by the respective second clamping mechanisms 43, thereby reducing the frequency of the reciprocating motion of the transfer robot 41 and improving the working efficiency.

Detection device

Referring to fig. 28, in the present embodiment, the inspection apparatus 5 includes a stage 51 to be inspected, a good stage 52, a defective cassette 53, an equidistant carrying mechanism 54, a metal detection mechanism 55, an insulation conduction detection mechanism 56, a needle height detection mechanism 57, and a positional detection mechanism 58; the metal detection mechanism 55, the insulation conduction detection mechanism 56, the needle height detection mechanism 57 and the position detection mechanism 58 are arranged between the to-be-detected carrier 51 and the good carrier 52 at equal intervals along the same direction; the metal detection mechanism 55, the insulation conduction detection mechanism 56, the needle height detection mechanism 57 and the position detection mechanism 58 are respectively provided with a defective product box 53 at one side close to the defective product carrier 52; the equidistant carrying mechanism 54 is arranged between the to-be-inspected carrying platform 51 and the good carrying platform 52; the second clamping mechanism 43 is used for placing the automobile sensor on the to-be-inspected carrying platform 51, and the equidistant carrying mechanism 54 is used for carrying the automobile sensor on the to-be-inspected carrying platform 51 to the metal detecting mechanism 55, the insulation conduction detecting mechanism 56, the needle height detecting mechanism 57 and the position detecting mechanism 58 in sequence. In operation, the finished automobile sensors after injection molding are sequentially placed on the carrier 51 to be inspected through the transfer device 4 (namely the second clamping mechanism 43), then the automobile sensors on the carrier 51 to be inspected are sequentially conveyed to the metal detection mechanism 55, the insulation conduction detection mechanism 56, the needle height detection mechanism 57 and the position detection mechanism 58 through the equidistant conveying mechanism 54, so that whether the automobile sensors are provided with the bushings 200 (the automobile sensors without the bushings 200 are automatically placed in the passing defective boxes 53 in the next conveying process) or not is detected through the metal detection mechanism 55, whether the terminals 300 are conducted (the automobile sensors which are not conducted continuously under the pressure-resistant working condition are automatically placed in the passing defective boxes 53 in the next conveying process) or not through the insulation conduction detection mechanism 56, whether the heights of the contact pins 301 are qualified (the automobile sensors with the unqualified heights of the contact pins 301 are automatically placed in the passing defective boxes 53 in the next conveying process) or not is detected through the needle height detection mechanism 57, whether the position of the contact pins 301 are detected through the position detection mechanism 58 (the automobile sensors with the unqualified heights of the contact pins 301 are automatically placed in the passing defective boxes 53 in the next conveying process) is detected through the insulating conduction detection mechanism 56, whether the terminal 300 is conducted (the automobile sensors with the position 301 are not continuously placed in the passing defective boxes 53 in the next conveying process), and whether the automobile sensors with the automatic sensor is automatically placed in the passing defective boxes 53 in the conveying process, and whether the passing automobile sensor is automatically detected through the passing through the carrier or not is detected through the automatic carrier 6. The equidistant carrying mechanism 54, the metal detecting mechanism 55, the insulation conducting detecting mechanism 56, the needle height detecting mechanism 57, the position detecting mechanism 58 and the packaging device 6 are all of the prior art, and will not be described in detail herein. In addition, since four automotive sensors are typically molded at a time within the injection mold 500, they are typically grouped together (i.e., not in the same row); if four automobile sensors are to be carried for detection at the same time, the detection mechanisms are required to be arranged on at least two opposite sides, so that the equipment cost is high and the occupied space is large; and the injection molding of the injection mold 500 takes time, so the detection efficiency is not improved by the simultaneous detection. Therefore, the to-be-detected carrier 51 may adopt a sliding design, when the second clamping mechanism 43 simultaneously places four automobile sensors on the to-be-detected carrier 51, the to-be-detected carrier 51 is controlled to slide first, so that two of the automobile sensors move to the position of the equidistant carrying mechanism 54 first, and after the two automobile sensors are carried away, the to-be-detected carrier 51 is controlled to slide continuously, so that the other two automobile sensors move to the position of the equidistant carrying mechanism 54, thereby not only reasonably utilizing injection molding time, but also reducing the number of each detecting mechanism. In addition, the to-be-inspected stage 51, the good stage 52, the metal detection mechanism 55, the insulation conduction detection mechanism 56, the needle height detection mechanism 57 and the position detection mechanism 58 may be provided with a slot structure for adapting to the automobile sensor, so that the automobile sensor may be positioned and fixed at each stage.
