DETAILED DESCRIPTION

[0035] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the specific embodiments of the present invention and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0036] In order to solve the technical problems in the prior art, the present invention is further described in conjunction with the accompanying drawings and embodiments:

[0037] like Figures 1 to 8 As shown, the embodiment of the present invention discloses an in-mold riveting device for an air conditioner outdoor unit chassis 9, comprising: a feeding device, a stamping die, a clamping device and a lifting device;

[0038] The feeding device is used to convey the rivet 3 into the die cavity of the stamping die, and the rivet 3 is also conveyed to the bolt positioning member of the jacking device; the jacking device jacks the rivet 3 to the forming position inside the die cavity of the stamping die, and the clamping device clamps the rivet 3;

[0039] The clamping device is provided with two clamping parts 11 that can move relatively to each other. When the clamping parts 11 are clamped, they have a molding position formed inside the mold cavity of the stamping die. After the rivet 3 is pushed upward to reach the molding position, the clamping parts 11 clamp the rivet 3; the stamping die is used to stamp the air conditioner outdoor unit chassis 9 and the rivet 3 to complete the riveting process.

[0040] According to the in-mold riveting device for the chassis 9 of the air conditioner outdoor unit of the present invention, the present invention mainly includes a feeding device, a stamping die, a clamping device and a lifting device. Specifically, the stamping die includes an upper die 6, a lower die and an upper die punch 10. The upper die 6 and the lower die have a cavity when they are stamped together. The chassis 9 of the air conditioner outdoor unit is placed on the cavity before stamping, and the upper die 6 and the lower die are cooperated to complete the stamping of the rivet 3 and the chassis 9 of the air conditioner outdoor unit. The present invention transports the rivet 3 to the inside of the die cavity of the stamping die and to the bolt positioning member of the lifting device by the feeding device, and the rivet 3 is lifted by the lifting device. To the forming position inside the stamping die cavity, it is convenient for the clamping device to clamp the rivet 3. The clamping piece 11 is composed of two halves, which can slide back and forth. The rivet 3 is lifted upward by the jacking device to push open the forming die. After the rivet 3 is accurately delivered to the specified position, the clamping piece 11 is reset to clamp the rivet 3, and the chassis parts are grabbed into the mold cavity. The punch press is pressed down, and the upper die 6 first presses the air-conditioning outdoor unit chassis 9 downward, so that the rivet 3 is inserted into the circular hole of the air-conditioning outdoor unit chassis 9. The punch press continues to press down, and the upper die punch 10 is connected to the rivet 3 to start tightening, completing the riveting process.

[0041] In one embodiment of the present invention, the jacking device is provided with a jacking cylinder 7 and a bolt positioning seat 8, the bolt positioning seat 8 is fixedly connected to the driving end of the jacking cylinder 7, the bolt positioning seat 8 is provided with a positioning hole for positioning the rivet 3, the positioning hole is adapted to the rivet 3, and the jacking cylinder 7 drives the rivet 3 to move in the vertical direction.

[0042] In this embodiment, when the rivet 3 falls into the positioning hole of the bolt positioning seat 8, the bolt positioning seat 8 will position the rivet 3, and the lifting cylinder 7 drives the bolt positioning seat 8 to reciprocate in the vertical direction. After the lifting cylinder 7 lifts the rivet 3 to the forming position inside the die cavity of the stamping die, the lifting cylinder 7 resets and retracts, waiting for the next rivet 3 to fall into the positioning hole of the bolt positioning seat 8. Among them, whether the rivet 3 falls into the positioning hole of the bolt positioning seat 8 can be completed by using a visual sensor. The visual sensor can more accurately identify whether the rivet 3 falls into the positioning hole of the bolt positioning seat 8 to avoid material leakage. The cylinder can ensure that the rivet 3 is lifted to the forming position inside the die cavity of the stamping die, thereby improving the efficiency and accuracy of lifting the rivet 3 to the forming position.

[0043] In one embodiment of the present invention, the clamping device also includes a reset spring 12, and the reset spring 12 is fixedly connected to the clamping piece 11. The reset spring 12 is also fixed to the stamping die. When the rivet 3 is pushed upward, the rivet 3 pushes the clamping piece 11 open to compress the reset spring 12, and the clamping piece 11 slides on both sides. After the rivet 3 reaches the forming position, the reset spring 12 is reset, and the clamping piece 11 clamps the rivet 3.

[0044] In this embodiment, after the rivet 3 reaches the forming position, the return spring 12 can automatically return to its original state after the external force of the rivet 3 squeezing the return spring 12 disappears, thereby driving the connected clamping piece 11 to reset. The use of the return spring 12 can bring about an automatic reset function, improve convenience and quick response, and has strong adaptability. When the return spring 12 cooperates with the relatively moving clamping piece 11 to work, the rivet 3 is lifted upward by the lifting cylinder 7, and the nut end of the rivet 3 pushes the clamping piece 11 open. After the rivet 3 is accurately sent to the forming position, the nut end of the rivet 3 has exceeded the height of the clamping piece 11, and the nut end of the rivet 3 cannot squeeze the clamping piece 11. The return spring 12 automatically returns to its original state after the external force squeezing the rivet 3 disappears, the return spring 12 is reset, and the clamping piece 11 clamps the rivet 3.

[0045] In another embodiment of the present invention, the clamping device further comprises a reset cylinder, which is fixedly connected to the clamping piece 11, and is also fixed to the stamping die, and cooperates with the sensor. When the rivet 3 is pushed upward, the sensor identifies the rivet 3, and the reset cylinder retracts to open the clamping piece 11. When the sensor identifies that the rivet 3 is lifted to the molding position inside the stamping die cavity, the reset cylinder is driven to reset, and the clamping piece 11 clamps the rivet 3. In this embodiment, in the application scenario of frequent production operations, the use of the reset cylinder is better than the reset spring 12. Since the reset spring 12 is affected by the elastic force, during frequent operations, the elastic force of the reset spring 12 may be unable to effectively clamp the rivet 3. The use of the reset cylinder can clamp the rivet 3 more accurately.

[0046] In one embodiment of the present invention, the clamping end of the clamping piece 11 has a first inclined surface on the lower side, and the first inclined surface is used to cooperate with the nut end of the rivet 3 to push the clamping piece 11 to both sides. In this embodiment, in the process of the rivet 3 being lifted upward by the lifting cylinder 7, in order to facilitate the rivet 3 to push the clamping piece 11 open, the first inclined surface is provided on the lower side of the clamping surface of the clamping piece 11, so that in the process of lifting the rivet 3 upward, the side surface of the nut end of the rivet 3 will slowly push the clamping piece 11 to both sides along the inclined surface of the first inclined surface, so as to facilitate the rivet 3 to be lifted to the forming position inside the die cavity of the stamping die.

[0047] In one embodiment of the present invention, a second inclined portion is provided on the outer side of the top end of the bolt locating seat 8, and the second inclined portion is used to cooperate with the first inclined portion during the resetting process of the reset spring 12, so that the clamping member 11 clamps the rivet 3. In this embodiment, there are two situations when the rivet 3 falls into the positioning hole of the bolt locating seat 8. The first is that the screw rod of the rivet 3 falls completely into the positioning hole, and the second is that the screw rod of the rivet 3 falls completely into the positioning hole with an exposed rod portion. According to the first situation, when the clamping member 11 resets and clamps the rivet 3, it will first clamp the bolt locating seat 8, and rely on the top surface of the clamping member 11 to cooperate with the bottom surface of the nut end of the rivet 3, and the lifting cylinder 7 will retract to pull the rivet 3 out of the positioning hole of the bolt locating seat 8, until the bolt locating seat 8 withdraws from the clamping surface of the clamping member 11, and the clamping member 11 completes the clamping of the rivet 3, and the top of the bolt locating seat 8 A second inclined portion is provided on the outer side of the end to cooperate with the first inclined portion on the lower side of the clamping end of the clamping piece 11, which can reduce the retraction stroke of the lifting cylinder 7 and complete the clamping of the rivet 3 more quickly; according to the second situation, when the clamping piece 11 is reset to clamp the rivet 3, the clamping surface of the clamping piece 11 can directly clamp the rivet 3. In order to avoid the clamping piece 11 colliding with the bolt positioning seat 8 when it is reset, a second inclined portion is provided on the outer side of the top end of the bolt positioning seat 8. During the resetting process of the clamping piece 11, the clamping surface of the clamping piece 11 cannot collide with the bolt positioning seat 8. At the same time, the second inclined portion can cooperate with the first inclined portion to continue to lift the rivet 3.

[0048] In one embodiment of the present invention, the feeding device is provided with a vibration plate 2, a feeding guide 4 and a straight vibrator 5, wherein the feeding guide 4 is connected to the vibration plate 2, and the straight vibrator 5 is assembled at the bottom of the feeding guide 4. The vibration plate 2 is a feeding device with automatic directional sorting, which automatically and orderly arranges the disordered rivets 3 by vibration and accurately transports them to the next process; the feeding guide 4 is used in conjunction with the vibration plate 2 to further guide the rivets 3 transported by the vibration plate 2 to a specific position. The straight vibrator 5, whose full name is a linear feeder, is a device that assists the vibration plate 2 in riveting the materials 3.

[0049] In one embodiment of the present invention, the stamping die also has a limiting plate, and the limiting plate is also provided with a blanking hole. The discharge end of the feeding guide rail 4 cooperates with the limiting plate. When the rivet 3 of the feeding guide rail 4 is transmitted to the blanking hole of the limiting plate, the rod of the rivet 3 falls into the positioning hole of the screw positioning seat.

[0050] In one embodiment of the present invention, the in-mold riveting device of the air conditioner outdoor unit chassis 9 is further provided with a distance sensor, and the distance sensor is used to identify the distance between the two clamping parts 11;

[0051] When the two clamping members 11 are clamped relative to each other, there is a preset distance D, and the distance sensor obtains the relative distance d at which the clamping member 11 clamps the rivet 3 after the rivet 3 is lifted up to the forming position;

[0052] If the relative distance d>the preset distance D, the stamping die is controlled to stop stamping.

[0053] In this embodiment, when there are unqualified rivets 3, the clamping part of the screw rod of rivet 3 will have an extra protruding part. When the protruding part of the screw rod of rivet 3 is clamped by the clamping piece 11, rivet 3 will be tilted. When the tilted rivet 3 is stamped together with the air-conditioning outdoor unit chassis 9, it cannot be docked with the air-conditioning outdoor unit chassis 9, and the air-conditioning outdoor unit chassis 9 will be damaged during stamping. Therefore, when the two clamping parts 11 are relatively clamped, a preset distance is set, which is the distance when the clamping parts 11 are relatively clamped and fully fitted. If there is a protruding part on the clamping surface of the screw rod of the rivet 3, the clamping part 11 will be pushed open, and the clamping parts 11 cannot be relatively clamped and fully fitted. There is a distance between the clamping surfaces of the two clamping parts 11. By comparing the relative distance between the two clamping parts 11 with the preset distance through the distance sensor, it can be identified whether there is an extra protruding part in the clamping part of the screw rod of the rivet 3, thereby avoiding the tilting of the clamped rivet 3 and damaging the air-conditioning outdoor unit chassis 9 during stamping, thereby ensuring the pass rate of the stamping of the air-conditioning outdoor unit chassis 9 and the rivet 3.

[0054] In one embodiment of the present invention, a positioning rod 13 is further provided on the stamping die, and the positioning rod 13 is used to position the chassis 9 of the air conditioner outdoor unit.

[0055] The present invention is composed of an automatic feeding device consisting of a vibration plate 2, a feeding guide rail 4, and a straight vibrator 5, which automatically conveys the rivet 3 to the interior of the mold, and the lifting cylinder 7 accurately lifts the material, lifts the rivet 3 from bottom to top, and reaches the molding position. The clamping piece 11 is composed of left and right halves, which can slide back and forth, and has a return spring 12 on the rear side. The rivet 3 is lifted upward by the lifting cylinder 7, and the clamping piece 11 is pushed open. After the rivet 3 is accurately delivered to the specified position, the spring is reset to clamp the rivet 3, and then a manipulator is used to grab the air conditioner outdoor unit chassis 9 part into the mold cavity, and the circular hole of the chassis is aligned with the head of the rivet 3 through the precise positioning structure of the mold positioning rod 13, and then the punch press is pressed down. Under the action of precise positioning, the circular hole of the chassis is inserted into the rivet 3, and punched to complete the riveting process.

[0056] On the other hand, the present invention also provides an in-mold riveting method for an air conditioner outdoor unit chassis 9, comprising the following steps:

[0057] The rivet 3 is conveyed to the cavity of the stamping die by a feeding device, and the rivet 3 is also conveyed to the bolt positioning member of the jacking device;

[0058] The rivet 3 is lifted to the forming position inside the die cavity of the stamping die by using a lifting device, and the clamping device clamps the rivet 3;

[0059] The clamping device is provided with two clamping members 11 that can move relatively. When the clamping members 11 are clamped, a forming position is formed inside the die cavity of the stamping die. After the rivet 3 is pushed up to the forming position, the clamping members 11 clamp the rivet 3.

[0060] A manipulator is used to grab the chassis 9 of the air conditioner outdoor unit and put it into the cavity of the stamping die. The stamping die stamps the chassis 9 of the air conditioner outdoor unit and the rivet 3 to complete the riveting process.

[0061] The in-mold riveting device for the air-conditioning outdoor unit chassis 9 mentioned in the present invention is an automatic feeding device composed of a vibration plate 2, a feeding guide rail 4, and a straight vibrator 5. The rivet 3 is automatically conveyed to the inside of the mold, and the material is accurately lifted by the lifting cylinder 7, and the rivet 3 is lifted from bottom to top to reach the molding position. The clamping piece 11 is composed of left and right halves, which can slide back and forth, and there are return springs 12 on the rear side. The rivet 3 is lifted upward by the lifting cylinder 7, and the clamping piece 11 is pushed open. After the rivet 3 is accurately sent to the specified position, the spring is reset to clamp the rivet 3. Subsequently, a manipulator is used to grab the air-conditioning outdoor unit chassis 9 parts into the mold cavity, and the circular hole of the chassis is aligned with the head of the rivet 3 through the precise positioning structure of the mold positioning rod 13, and then the punch press is pressed down. Under the action of precise positioning, the circular hole of the chassis is inserted into the rivet 3 and punched to complete the riveting process. This production method can not only improve production efficiency, but more importantly, it can ensure the safety of operators; it improves the production efficiency of the riveting process of the compressor bolts of the air-conditioning outdoor unit chassis 9: the traditional manual operation method can produce 3 to 4 pieces per minute, and the use of this invention technology can produce 15 to 20 pieces per minute, and the production efficiency is increased by 5 times; it improves the on-site production safety of the riveting process of the compressor of the air-conditioning outdoor unit chassis 9: the use of this invention technology can realize unmanned production and improve on-site production safety.

[0062] In another embodiment of the present invention, the in-mold riveting method of the air conditioner outdoor unit chassis 9 of the present invention further adopts a distance sensor provided in the in-mold riveting device of the air conditioner outdoor unit chassis 9, and the distance sensor is used to identify the distance between the two clamping parts 11;

[0063] When the two clamping members 11 are clamped relative to each other, there is a preset distance D, and the distance sensor obtains the relative distance d at which the clamping member 11 clamps the rivet 3 after the rivet 3 is lifted up to the forming position;

[0064] If the relative distance d>the preset distance D, the stamping die is controlled to stop stamping.

[0065] In this embodiment, when there are unqualified rivets 3, the clamping part of the screw rod of rivet 3 will have an extra protruding part. When the protruding part of the screw rod of rivet 3 is clamped by the clamping piece 11, rivet 3 will be tilted. When the tilted rivet 3 is stamped together with the air-conditioning outdoor unit chassis 9, it cannot be docked with the air-conditioning outdoor unit chassis 9, and the air-conditioning outdoor unit chassis 9 will be damaged during stamping. Therefore, when the two clamping parts 11 are relatively clamped, a preset distance is set, which is the distance when the clamping parts 11 are relatively clamped and fully fitted. If there is a protruding part on the clamping surface of the screw rod of the rivet 3, the clamping part 11 will be pushed open, and the clamping parts 11 cannot be relatively clamped and fully fitted. There is a distance between the clamping surfaces of the two clamping parts 11. By comparing the relative distance between the two clamping parts 11 with the preset distance through the distance sensor, it can be identified whether there is an extra protruding part in the clamping part of the screw rod of the rivet 3, thereby avoiding the tilting of the clamped rivet 3 and damaging the air-conditioning outdoor unit chassis 9 during stamping, thereby ensuring the pass rate of the stamping of the air-conditioning outdoor unit chassis 9 and the rivet 3.

[0066] In summary, after reading the present invention document, ordinary technicians in this field can make various other corresponding transformation schemes based on the technical scheme and technical concept of the present invention without creative mental work, which all fall within the scope of protection of the present invention.
