Description

Technical Field

[0001] This utility model relates to the field of air conditioner outdoor unit chassis technology, and in particular to an in-mold riveting device for air conditioner outdoor unit chassis. Background Technology

[0002] After the air conditioner chassis parts are molded, a bolt riveting process is required. Since the holes on the chassis parts need to be fitted onto the bolt heads before riveting, the current process usually involves manually inserting the bolts into the lower mold, then lifting the chassis, fitting the three round holes onto the bolt heads, and then stamping. Because the gap between the bolt heads and the round holes on the chassis is small, this method is time-consuming and labor-intensive, resulting in low production efficiency, poor reliability, and high production costs. Furthermore, in manual operation, even slight negligence can lead to accidents where fingers are caught in the upper and lower molds. Therefore, there are still significant safety hazards in the current press-riveting process. Utility Model Content

[0015] As a further improvement of this utility model: the in-mold riveting device for the air conditioner outdoor unit chassis is also provided with a distance sensor, which is used to identify the distance between the two clamping parts;

[0016] When the two clamping parts are clamped relative to each other, there is a preset distance D. The distance sensor obtains the relative distance d between the clamping parts after the rivet is pushed upward to the forming position and the rivet is clamped.

[0017] If the relative distance d > the preset distance D, then control the stamping die to stop stamping.

[0018] As a further improvement of this utility model: the stamping die is also provided with a positioning rod, which is used to position the air conditioner outdoor unit chassis.

[0035] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

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

[0037] like Figures 1 to 8 As shown in the figure, this utility model embodiment discloses an in-mold riveting device for an air conditioner outdoor unit chassis, including: a feeding device, a stamping die, a clamping device, and a lifting device;

[0038] The feeding device is used to transport the rivet 3 into the cavity of the stamping die, and the rivet 3 is also transported to the bolt positioning part of the lifting device; the lifting device lifts the rivet 3 to the forming position inside the 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 relative to each other. When the clamping parts 11 are clamped, they have a forming position that forms inside the die cavity of the stamping die. After the rivet 3 is pushed upward to the forming 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 air conditioner outdoor unit chassis of this utility model, the utility model 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 closed during stamping. The air conditioner outdoor unit chassis 9 is placed on the cavity before stamping. The upper die 6 and the lower die work together to stamp the rivet 3 to the air conditioner outdoor unit chassis 9. In this utility model, the rivet 3 is fed into the cavity of the stamping die and onto the bolt positioning part of the lifting device by the feeding device. The lifting device then lifts the rivet 3... The jacking device lifts the rivet 3 to the forming position inside the die cavity of the stamping mold, making it convenient for the clamping device to hold the rivet 3. The clamping part 11 consists of two halves, left and right, which can slide back and forth. The jacking device lifts the rivet 3 upward, opens the forming die, and accurately delivers the rivet 3 to the designated position. Then, the clamping part 11 resets and clamps the rivet 3, grabbing the chassis part into the die cavity. The press presses down, and the upper die 6 first presses the air conditioner outdoor unit chassis 9 downward, so that the rivet 3 fits into the round hole of the air conditioner outdoor unit chassis 9. The press press continues to press down, and the upper die punch 10 connects to the rivet 3 to start the tightening work, completing the riveting process.

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

[0042] In this embodiment, after the rivet 3 falls into the positioning hole of the bolt positioning seat 8, the bolt positioning seat 8 positions the rivet 3. The lifting cylinder 7 drives the bolt positioning seat 8 to reciprocate vertically. After the lifting cylinder 7 lifts the rivet 3 to the forming position inside the die cavity, 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. Whether the rivet 3 falls into the positioning hole of the bolt positioning seat 8 can be determined by using a vision sensor. The vision sensor can more accurately identify whether the rivet 3 has fallen into the positioning hole of the bolt positioning seat 8, avoiding material leakage. Combined with the cylinder, it ensures that the rivet 3 is lifted to the forming position inside the die cavity, improving the efficiency and accuracy of lifting the rivet 3 to the forming position.

[0043] In one embodiment of this utility model, the clamping device further includes a return spring 12, which is fixedly connected to the clamping member 11 and also fixed to the stamping die. When the rivet 3 is pushed upward, the rivet 3 pushes open the clamping member 11 and compresses the return spring 12. The clamping member 11 slides on both sides. After the rivet 3 reaches the forming position, the return spring 12 returns to its original position, and the clamping member 11 clamps the rivet 3.

[0044] In this embodiment, the return spring 12 can automatically return to its original state after the external force of the rivet 3 pressing the return spring 12 disappears after the rivet 3 reaches the forming position, thereby driving the clamping component 11 connected to it to reset. The use of the return spring 12 can bring an automatic reset function, improve convenience and fast response, and has strong adaptability. When the return spring 12 works with the relatively moving clamping component 11, the lifting cylinder 7 lifts the rivet 3 upward, and the nut end of the rivet 3 pushes open the clamping component 11. After the rivet 3 is accurately delivered to the forming position, the nut end of the rivet 3 has exceeded the height of the clamping component 11. The nut end of the rivet 3 can no longer press the clamping component 11. The return spring 12 automatically returns to its original state after the external force of the rivet 3 pressing disappears. The return spring 12 resets, and the clamping component 11 clamps the rivet 3.

[0045] In another embodiment of this utility model, the clamping device further includes a reset cylinder, which is fixedly connected to the clamping component 11 and also fixed to the stamping die. With the assistance of a sensor, when the rivet 3 is pushed upwards, the sensor detects the rivet 3 and the reset cylinder retracts to open the clamping component 11. When the sensor detects that the rivet 3 has risen to the forming position inside the die cavity, it drives the reset cylinder to reset, and the clamping component 11 clamps the rivet 3. In this embodiment, in applications with frequent production operations, the reset cylinder is more effective than the reset spring 12. Because the reset spring 12 is affected by elasticity, frequent operations may cause the elasticity of the reset spring 12 to fail to effectively clamp the rivet 3. Using a reset cylinder can clamp the rivet 3 more accurately.

[0046] In one embodiment of this utility model, the clamping end of the clamping member 11 has a first inclined surface on its lower side. The first inclined surface is used to cooperate with the nut end of the rivet 3 to push the clamping member 11 open to both sides. In this embodiment, during the process of the lifting cylinder 7 lifting the rivet 3 upward, in order to facilitate the rivet 3 to push the clamping member 11 open, a first inclined surface is provided on the lower side of the clamping surface of the clamping member 11. This allows the nut end side of the rivet 3 to slowly push the clamping member 11 open to both sides along the inclined surface of the first inclined surface during the process of lifting the rivet 3 upward, making it easier to lift the rivet 3 to the forming position inside the die cavity of the stamping mold.

[0047] In one embodiment of this utility model, a second inclined surface is provided on the outer side of the top of the bolt positioning seat 8. The second inclined surface is used to cooperate with the first inclined surface during the reset process of the reset spring 12, so that the clamping member 11 clamps the rivet 3. In this embodiment, there are two situations in which the rivet 3 falls into the positioning hole of the bolt positioning seat 8: first, the screw of the rivet 3 falls completely into the positioning hole; second, the screw of the rivet 3 falls completely into the positioning hole, with an exposed shank. According to the first situation, when the clamping member 11 resets and clamps the rivet 3, it first clamps the bolt positioning seat 8, and relies on the top surface of the clamping member 11 to cooperate with the bottom surface of the nut end of the rivet 3. The lifting cylinder 7 retracts, pulling the rivet 3 out of the positioning hole of the bolt positioning seat 8. When the bolt positioning seat 8 exits the clamping surface of the clamping member 11, the clamping member 11 completes the clamping of the rivet 3, and the top of the bolt positioning seat 8 is lifted. The second inclined surface on the outer side of the clamping part 11 cooperates with the first inclined surface on the lower side of the clamping end of the clamping part 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 case, when the clamping part 11 resets to clamp the rivet 3, the clamping surface of the clamping part 11 can directly clamp the rivet 3. In order to avoid the clamping part 11 colliding with the bolt positioning seat 8 when resetting, the second inclined surface is provided on the outer side of the top of the bolt positioning seat 8. During the resetting process of the clamping part 11, the clamping surface of the clamping part 11 cannot collide with the bolt positioning seat 8. At the same time, the second inclined surface can cooperate with the first inclined surface to continue to lift the rivet 3.

[0048] In one embodiment of this utility model, the feeding device includes a vibratory feeder 2, a feeding guide rail 4, and a linear vibrator 5. The feeding guide rail 4 is connected to the vibratory feeder 2, and the linear vibrator 5 is mounted on the bottom of the feeding guide rail 4. The vibratory feeder 2 is an automatic orientation and sorting feeding device that automatically and orderly arranges disordered rivets 3 through vibration and accurately conveys them to the next process. The feeding guide rail 4 is used in conjunction with the vibratory feeder 2 to further guide the rivets 3 conveyed by the vibratory feeder 2 to a specific position. The linear vibrator 5, also known as a linear feeder, is a device that assists the vibratory feeder 2 in riveting materials 3.

[0049] In one embodiment of the present invention, the stamping die further includes a limiting plate, the limiting plate is also provided with a blanking hole, the discharge end of the feeding guide 4 cooperates with the limiting plate, and when the rivet 3 of the feeding guide 4 is delivered to the blanking hole of the limiting plate, the rod of the rivet 3 enters the positioning hole of the screw positioning seat.

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

[0051] When the two clamping parts 11 are clamped relative to each other, there is a preset distance D. The distance sensor obtains the relative distance d at which the clamping parts 11 clamp the rivet 3 after the rivet 3 is pushed upward to the forming position.

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

[0053] In this embodiment, when there are defective products in the rivet 3, the screw clamping part of the rivet 3 will have an extra protruding part. When the protruding part of the screw of the rivet 3 is clamped by the clamping part 11, the rivet 3 will also tilt. When the tilted rivet 3 is stamped with the air conditioner outdoor unit chassis 9, it cannot be connected with the air conditioner outdoor unit chassis 9, and the air conditioner outdoor unit chassis 9 will be damaged during the stamping process. Therefore, when the two clamping parts 11 are clamped relative to each other, the preset distance is the distance when the clamping parts 11 are fully clamped and fit together. If there is a protruding part on the clamping surface of the rivet 3 screw, it will push the clamping parts 11 open, and the clamping parts 11 cannot be fully clamped and fit together. 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 rivet 3 screw. This can avoid the phenomenon of tilting the clamping rivet 3, avoid damage to the air conditioner outdoor unit chassis 9 during stamping, and ensure the pass rate of stamping of the air conditioner outdoor unit chassis 9 and rivet 3.

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

[0055] This utility model consists of an automatic feeding device composed of a vibratory plate 2, a feeding guide rail 4, and a linear vibrator 5. The device automatically feeds the rivets 3 into the mold. The lifting cylinder 7 precisely lifts the rivets 3 from bottom to top to the forming position. The clamping part 11 is composed of two halves that can slide back and forth. Each half has a return spring 12. The lifting cylinder 7 lifts the rivets 3 upward, opens the clamping part 11, and precisely delivers the rivets 3 to the designated position. Then the springs return to their original positions and clamp the rivets 3. Subsequently, a robotic arm picks up the air conditioner outdoor unit chassis 9 part into the mold cavity. Through the precise positioning structure of the mold positioning rod 13, the round hole of the chassis is aligned with the head of the rivet 3. Then the punch press presses down. Under the precise positioning, the round hole of the chassis fits into the rivet 3 and is punched to complete the riveting process.

[0056] On the other hand, this application also provides a method for in-mold riveting of an air conditioner outdoor unit chassis, including the following steps:

[0057] The rivet 3 is fed into the cavity of the stamping die by a feeding device, and the rivet 3 is also fed to the bolt positioning part of the lifting device.

[0058] A lifting device is used to lift the rivet 3 to the forming position inside the die cavity of the stamping die, and a clamping device clamps the rivet 3.

[0059] The clamping device is equipped with two relatively movable clamping parts 11. When the clamping parts 11 are clamped, they form a forming position inside the mold cavity of the stamping die. After the rivet 3 is pushed upward to the forming position, the clamping parts 11 clamp the rivet 3.

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

[0061] The air conditioner outdoor unit chassis in-mold riveting device mentioned in this utility model is an automatic feeding device composed of a vibratory plate 2, a feeding guide rail 4, and a linear vibrator 5. It automatically feeds the rivets 3 into the inside of the mold. The lifting cylinder 7 precisely lifts the rivets 3 from bottom to top to the forming position. The clamping part 11 is composed of two halves, which can slide back and forth. There are return springs 12 on the rear side. The lifting cylinder 7 lifts the rivets 3 upward, opens the clamping part 11, and precisely delivers the rivets 3 to the designated position. After the springs return, the rivets 3 are clamped. Then, a robotic arm grabs the air conditioner outdoor unit chassis 9 part into the mold cavity. Through the precise positioning structure of the mold positioning rod 13, the round hole of the chassis is aligned with the head of the rivet 3. Then, the punch press presses down. Under the action of precise positioning, the round hole of the chassis fits into the rivet 3 and is punched to complete the riveting process. This production method not only improves production efficiency but, more importantly, ensures the safety of operators. It also improves the production efficiency of the riveting process for the compressor bolts of the air conditioner outdoor unit chassis 9: the traditional manual operation method can produce 3-4 pieces per minute, while using this utility model technology, it can produce 15-20 pieces per minute, increasing production efficiency by 5 times. Furthermore, it improves the on-site production safety of the air conditioner outdoor unit chassis 9 compressor riveting process: using this utility model technology can achieve unmanned production and improve on-site production safety.

[0062] In another embodiment of this application, the in-mold riveting method for the air conditioner outdoor unit chassis of this utility model also employs a distance sensor in the in-mold riveting device for the air conditioner outdoor unit chassis, the distance sensor being used to identify the distance between the two clamping parts 11;

[0063] When the two clamping parts 11 are clamped relative to each other, there is a preset distance D. The distance sensor obtains the relative distance d at which the clamping parts 11 clamp the rivet 3 after the rivet 3 is pushed upward to the forming position.

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

[0065] In this embodiment, when there are defective products in the rivet 3, the screw clamping part of the rivet 3 will have an extra protruding part. When the protruding part of the screw of the rivet 3 is clamped by the clamping part 11, the rivet 3 will also tilt. When the tilted rivet 3 is stamped with the air conditioner outdoor unit chassis 9, it cannot be connected with the air conditioner outdoor unit chassis 9, and the air conditioner outdoor unit chassis 9 will be damaged during the stamping process. Therefore, when the two clamping parts 11 are clamped relative to each other, the preset distance is the distance when the clamping parts 11 are fully clamped and fit together. If there is a protruding part on the clamping surface of the rivet 3 screw, it will push the clamping parts 11 open, and the clamping parts 11 cannot be fully clamped and fit together. 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 rivet 3 screw. This can avoid the phenomenon of tilting the clamping rivet 3, avoid damage to the air conditioner outdoor unit chassis 9 during stamping, and ensure the pass rate of stamping of the air conditioner outdoor unit chassis 9 and rivet 3.

[0066] In summary, any other corresponding modifications made by those skilled in the art after reading this utility model document, based on the technical solution and concept of this utility model without creative mental effort, shall all fall within the scope of protection of this utility model.
