In this embodiment, as... Figure 3As shown, the turntable 1 includes a racetrack-shaped track 11, a transmission chain 12, and a transmission drive 13 that drives the transmission chain 12 to move. The support fixture 9 is slidably disposed on the racetrack-shaped track 11 and fixedly connected to the transmission chain 12. The transmission drive 13 drives the transmission chain 12 to move along the racetrack-shaped track 11. In some embodiments, a belt can be used instead of the transmission chain 12. The transmission drive 13 may be a rotary motor or the like.

[0054] Combination Figure 1 and Figure 2 The transport line 2 is located on one side of the turntable 1. The transport line 2 is used to transport detonator chips. Specifically, the transport line 2 transports a loading fixture 21 containing detonator chips. The transport line 2 is equipped with lifting mechanisms 22 corresponding to the loading and unloading stations. Each lifting mechanism 22 includes a lifting bracket 221, a lifting drive component 222, a lifting plate 223, and a stop drive component 224. The lifting drive component 222 and the stop drive component 224 are respectively mounted on the lifting bracket 221. The lifting drive component 222 is connected to the lifting plate 223. The lifting plate 223 is provided with a positioning post 225 for positioning the loading fixture 21. The loading fixture 21 has a hole that mates with the positioning post 225. The stop drive 224 is provided on the lifting bracket 221. The stop drive 224 is used to stop the loading fixture 21, so that the loading fixture 21 located above the lifting plate 223 on the transport line 2 can be aligned with the positioning post 225. The stop drive 224 includes, but is not limited to, cylinders, hydraulic rods, electric push rods, etc. The lifting drive 222 includes, but is not limited to, cylinders, hydraulic rods, electric push rods, etc.

[0055] like Figure 1 As shown, the loading robot 3 is set up corresponding to the loading station. The loading robot 3 is used to transfer the detonator chips located in the loading fixture 21 on the transport line 2 to the carrying fixture 9 located in the loading station. The loading robot 3 includes a connected XYZ three-axis moving platform and a picking device.

[0056] An electrical testing mechanism 4 is set corresponding to the electrical testing station. The electrical testing mechanism 4 is used to perform electrical performance testing on the detonator chip carried by the support fixture 9 at the electrical testing station. The electrical testing mechanism 4 includes an electrical testing bracket, an electrical testing lifting platform, and an electrical testing drive component. The electrical testing drive component connects the electrical testing bracket and the electrical testing lifting platform to drive the lifting platform to move up and down. The electrical testing lifting platform is provided with electrical testing terminals, which are used to contact and conduct electricity with the detonator chip on the support fixture 9 at the electrical testing station to test the detonator chip. The electrical testing drive component includes, but is not limited to, cylinders, hydraulic rods, and electric push rods. To ensure precise alignment between the electrical testing terminals and the detonator chip at the electrical testing station, in some embodiments, such as... Figure 3 As shown, the turntable 1 is provided with a limiting drive 41 and a limiting block 42. The limiting drive 41 connects the turntable 1 and the limiting block 42. The limiting block 42 is used to limit the bearing fixture 9 located at the electrical testing station. In this embodiment, the limiting block 42 is provided with a notch, and the bearing fixture 9 is provided with a protrusion for cooperating with the notch.

[0057] Please combine Figure 4 and Figure 5 To prevent detonator chips from accidentally falling off the support fixture 9, in one or more embodiments, the support fixture 9 includes a base 91 and a support seat 92 and a locking assembly 93 respectively disposed on the base 91. The support seat 92 is provided with a support groove for supporting detonator chips, and there are multiple support grooves. The support seat 92 is also provided with a positioning groove 921 for positioning the material strip. One side wall of the positioning groove 921 is a positioning wall 922. It should be noted that the detonator chip material transported by the transport line 2 is in the form of a sheet, which includes the material strip, and multiple detonator chips are connected to one side of the material strip. The locking assembly 93 includes a hook 931, an elastic element 932, and a pushing component 933. The hook 931 is connected to the pushing component 933. 33. The hook 931 has a hook portion 934, which cooperates with the positioning wall 922 to form a limiting area for limiting the material strip, so that the material strip is completely limited and the sheet material will not move. The elastic member 932 abuts against the pushing member 933 and the bearing seat 92. The elastic member 932 can be a spring, a sheet, etc. The turntable 1 is provided with an unlocking drive member 14, which is used to push the pushing member 933 to unlock the locking component 93. The loading station and the unloading station are respectively provided with the unlocking drive member 14. Only when the unlocking drive member 14 drives the pushing member 933 to unlock the sheet material can the sheet material be removed from the bearing fixture 9. The unlocking drive member 14 includes, but is not limited to, a cylinder, a hydraulic rod, an electric push rod, etc.

[0058] In this embodiment, the inner side of the support seat 92 is provided with a first through hole, and the top of the support seat 92 is provided with a second through hole that communicates with the first through hole. One end of the hook 931 with a hook portion 934 passes through the first through hole, and the hook portion 934 passes through the second through hole. Specifically, the second through hole is located between two adjacent support grooves, which can effectively reduce the overall size of the support fixture 9 and allow the sheet metal to be more stably confined on the support seat 92.

[0059] Combination Figure 1 and Figures 6 to 9The tube cutting and sleeve assembly 5 is set corresponding to the sleeve station. The tube cutting and sleeve assembly 5 includes a tube releasing assembly 51, a tube pushing assembly 52, a tube cutting assembly 53 and a rotating sleeve assembly 54 arranged in sequence. The tube releasing assembly 51 is used to release the disc-shaped heat shrink tubing. The tube pushing assembly 52 is used to push the heat shrink tubing so that the heat shrink tubing passes through the cutting position of the tube cutting assembly 53. The tube cutting assembly 53 is used to cut the heat shrink tubing to make a heat shrink tubing segment. The rotating sleeve assembly 54 is used to carry the heat shrink tubing segment and sleeve the heat shrink tubing segment into the detonator chip carried by the carrying fixture 9 at the sleeve station.

[0060] like Figure 6 As shown, the tube pushing assembly 52 includes a tube pushing drive 521, a tube pushing block 522, a tube pushing lifting drive 523, a first clamping block 524, a second clamping block 525, and a limiting plate 526. The tube pushing drive 521 is connected to the tube pushing block 522 to drive the tube pushing block 522 to move back and forth, thereby causing the tube pushing block 522 to move closer to or away from the tube cutting assembly 53. The tube pushing lifting drive 523 is disposed on the tube pushing block 522 and connected to the first clamping block 524 to drive the first clamping block 524 to move up and down. The second clamping block 525 is directly or indirectly disposed on the tube pushing block 522 and corresponds to the first clamping block 524. The first clamping block 524 and the second clamping block 525 cooperate to clamp the heat shrink tubing released by the tube releasing assembly 51. The limiting plate 526 is located in front of the tube pushing block 522, and the limiting plate 526 is provided with a limiting hole for limiting the heat shrink tubing released by the tube releasing assembly 51. The tube pusher 521 includes, but is not limited to, cylinders, hydraulic rods, electric push rods, etc., and the tube pusher lifting 523 includes, but is not limited to, cylinders, hydraulic rods, electric push rods, etc. The opening and closing of the first clamping block 524 and the second clamping block 525 cooperates with the pushing of the tube pusher 521, so that the heat shrink tubing can be pushed toward the limiting hole.

[0061] To prevent the end of the heat shrink tubing from disengaging from the limiting hole when the pusher 521 drives the pusher block 522 backward, in this embodiment, the pusher assembly 52 further includes an upper clamping plate 527, a lower clamping plate 528, and a clamping drive 529. The lower clamping plate 528 is located below the upper clamping plate 527 to cooperate with it. The clamping drive 529 is connected to either the upper clamping plate 527 or the lower clamping plate 528. The lower clamping plate 528 is located behind the pusher block 522. The cooperation between the upper clamping plate 527 and the lower clamping plate 528 can clamp the rear region of the heat shrink tubing released by the tubing release assembly 51, thereby preventing the first clamping block 524 and / or the second clamping block 525 from driving the heat shrink tubing and causing the end of the heat shrink tubing to disengage from the limiting hole. The clamping drive 529 includes, but is not limited to, cylinders, hydraulic rods, electric push rods, etc. Optionally, the pusher 521 is disposed on the upper clamping plate 527.

[0062] The tube pushing assembly 52 further includes a pre-positioning plate 530. The pre-positioning plate 530 has pre-positioning holes for positioning the heat shrink tubing released by the tube releasing assembly 51. The pre-positioning plate 530 is located behind and close to the lower clamping plate 528. The presence of the pre-positioning plate 530 can organize the multiple heat shrink tubing released by the tube releasing assembly 51, so that the multiple heat shrink tubing can be kept in a row without stacking, thereby allowing the upper clamping plate 527 and the lower clamping plate 528 to better clamp the heat shrink tubing. Optionally, the pre-positioning plate 530 is fixedly connected to the upper clamping plate 527.

[0063] like Figure 8 and Figure 9 As shown, the rotating sleeve assembly 54 includes a first translation drive 541, a rotation drive 542, a rotating frame 543, a pressing plate 544, a pressing drive 545, an ejection plate 546, and an ejection drive 547. The first translation drive 541 is connected to the rotation drive 542 to drive the rotation drive 542 closer to or further away from the turntable 1. Multiple sleeve posts 5431 are respectively provided on both sides of the rotating frame 543. The sleeve posts 5431 are used to support heat shrink tubing sections. The rotation drive 542 is connected to the rotating frame 543 to drive the rotating frame. 543 rotates; the pressure plate 544 has a pressure portion 5441 corresponding to the peripheral wall of the sleeve post 5431, and the pressure driving member 545 connects the rotating frame 543 and the pressure plate 544 to drive the pressure portion 5441 to move closer to or away from the sleeve post 5431; the push-out driving member 547 connects the rotating frame 543 and the push-out plate 546, and the push-out plate 546 is provided with a clearance hole for avoiding the sleeve post 5431. The push-out plate 546 is used to push out the heat shrink tubing section sleeved on the sleeve post 5431. In this embodiment, the rotating driving member 542 drives the rotating frame 543 to rotate 180° reciprocatingly. The first translation drive component 541 includes, but is not limited to, cylinders, hydraulic rods, electric push rods, etc.; the pressing drive component 545 includes, but is not limited to, cylinders, hydraulic rods, electric push rods, etc.; the pushing drive component 547 includes, but is not limited to, cylinders, hydraulic rods, electric push rods, etc.; the rotation drive component 542 includes, but is not limited to, motors, rotary cylinders, etc.

[0064] Combination Figure 1 , Figure 6 and Figure 7In a preferred embodiment, the tube cutting and sleeve-making mechanism 5 further includes a switching component 55. The switching component 55 includes a second translational drive member. The driving direction of the second translational drive member is consistent with the axial direction of the rotation center axis of the rotating frame 543. The second translational drive member connects the tube pushing assembly 52 and the tube cutting assembly 53. The switching component 55 pushes the tube pushing assembly 52 and the tube cutting assembly 53 to translate synchronously. The plurality of sleeve posts 5431 on each side of the rotating frame 543 are divided into multiple groups. When the second translational drive member drives the tube pushing assembly 52 to move, the tube pushing assembly 52 has at least two dwelling positions. When the tube pushing assembly 52 is in different dwelling positions, the limiting holes on the limiting plate 526 correspond to different groups of sleeve posts 5431. In this embodiment, the tube pushing assembly 52 has two dwelling positions. Assuming the limiting plate 526 has 20 limiting holes, the number of sleeve posts 5431 on one side of the rotating frame 543 is 40. The second translation drive component includes, but is not limited to, cylinders, hydraulic rods, electric push rods, etc.

[0065] When the second translational drive causes the tube pusher assembly 52 to move toward a stationary position away from the tube release assembly 51, the upper clamping plate 527 and the lower clamping plate 528 will clamp the heat shrink tube to prevent it from retracting, so that the end of the heat shrink tube will fall off from the limiting hole. At the same time, since the rear area of ​​the heat shrink tube is clamped by the upper clamping plate 527 and the lower clamping plate 528, when the second translational drive causes the tube pusher assembly 52 to move, the upper clamping plate 527 and the lower clamping plate 528 will pull the tube release assembly 51 to release the tube, thereby ensuring the smoothness of the tube release assembly 51 releasing the tube.

[0066] like Figure 1 As shown, to facilitate the smooth insertion of the heat-shrink tubing segment into the sleeve post 5431, the sleeve station is further equipped with a pressing assembly 15. The pressing assembly 15 includes a first lifting drive and a pressing plate. The first lifting drive drives the pressing plate to rise and fall, and the pressing plate is used to press against the detonator chip on the support fixture 9 at the sleeve station. The first lifting drive includes, but is not limited to, a cylinder, a hydraulic rod, an electric push rod, etc.

[0067] The working steps of the tube cutting and sleeve mechanism 5 are briefly described as follows: The tube pushing and lifting drive 523 drives the first clamping block 524 to close towards the second clamping block 525, thereby clamping the heat shrink tubing with the first clamping block 524 and the second clamping block 525. The tube pushing drive 521 drives the tube pushing block 522 to move towards the turntable 1, so that the end of the heat shrink tubing is inserted into the sleeve column 5431. The tube cutting assembly 53 cuts the heat shrink tubing, forming a heat shrink tubing segment on the sleeve column 5431. Then, the clamping drive 529 drives the upper clamping plate 527 and the lower clamping plate 528 to close and clamp the heat shrink tubing. Then, the tube pushing and lifting drive 523 drives the first clamping block 524 to close towards the second clamping block 525. Clamping block 524 moves away from second clamping block 525, thus releasing the heat shrink tubing. Pushing drive 521 drives pushing block 522 to reset. Switching assembly 55 drives pushing assembly 52 to the next dwell position. Pushing lifting drive 523 drives first clamping block 524 to close towards second clamping block 525, thereby clamping the heat shrink tubing between first clamping block 524 and second clamping block 525. Clamping drive 529 drives upper clamping plate 527 to reset and release the heat shrink tubing. Pushing drive 521 drives pushing block 522 to move closer to turntable 1, so that the end of the heat shrink tubing is inserted into another set of sleeve columns on the same side of the rotating frame 543. In step 5431, the tube cutting assembly 53 cuts the heat shrink tubing, causing the sleeve post 5431 to form a heat shrink tubing segment. The clamping drive 529 drives the upper clamping plate 527 and the lower clamping plate 528 to close and clamp the heat shrink tubing. Then, the tube pushing and lifting drive 523 drives the first clamping block 524 away from the second clamping block 525, thereby releasing the heat shrink tubing. The switching assembly 55 drives the tube pushing assembly 52 to reset to the previous dwell position. The pressing drive 545 drives the pressing plate 544 to press against the heat shrink tubing segment located on the sleeve post 5431 to prevent the heat shrink tubing segment on the sleeve post 5431 from detaching from the sleeve post 5431 when the rotating frame 543 rotates. Then, the rotary drive 542 drives the rotary frame 543 to rotate 180°, and the first translation drive 541 drives the rotary drive 542 to move the rotary frame 543 closer to the detonator chip in the sleeve position. At the same time, the first lifting drive drives the lower pressure plate to descend so that the lower pressure plate presses against the detonator chip in the sleeve position, so that the sleeve post 5431 is aligned with the end of the detonator chip. The pressing drive 545 drives the pressing plate 544 to reset to release the heat shrink tubing section. Then, the ejection drive 547 drives the ejection plate 546 to move, so that the heat shrink tubing section on the sleeve post 5431 is transferred to the detonator chip.

[0068] Combination Figure 1 and Figure 10A heat-shrinking mechanism 6 is provided corresponding to the heat-shrinking station. The heat-shrinking mechanism 6 is used to heat the heat-shrinkable tubing segment on the detonator chip carried by the support fixture 9 at the heat-shrinking station, so that the heat-shrinkable tubing segment shrinks. The heat-shrinking mechanism 6 includes a heat-shrinking drive component 61, a heat-shrinkable body 62, a second lifting drive component 63, and a baffle 64. The heat-shrinking drive component 61 is connected to the heat-shrinkable body 62 to drive the heat-shrinkable body 62 closer to or further away from the support fixture 9 at the heat-shrinking station. The heat-shrinkable body 62 is provided with… The heat-shrinkable cavity is connected to an external heat source. The front side of the heat-shrinkable body 62 has an opening 65 connecting to the heat-shrinkable cavity. The second lifting drive component 63 is connected to a baffle 64, which is disposed on the front side of the heat-shrinkable body 62. The baffle 64 is used to close the opening 65, thereby reducing heat loss. This helps prevent the heat-shrinkable tube segment on the detonator chip from being affected by heat loss from the opening 65 before reaching the predetermined position, resulting in local heat shrinkage and poor subsequent heat shrinkage effect. The heat-shrinkable drive component 61 includes, but is not limited to, cylinders, hydraulic rods, electric push rods, etc.; the second lifting drive component 63 includes, but is not limited to, cylinders, hydraulic rods, electric push rods, etc.

[0069] Combination Figure 1 and Figure 11 A visual inspection mechanism 7 is set up corresponding to the appearance inspection station. The visual inspection mechanism 7 is used to perform appearance inspection on the detonator chips carried by the support fixture 9 at the appearance inspection station. The visual inspection mechanism 7 includes a CCD camera 71. To enable the visual inspection mechanism 7 to inspect a larger number of detonator chips in a short time, in this embodiment, the visual inspection mechanism 7 also includes a sliding assembly 72. The sliding assembly 72 includes a connected sliding drive and a sliding bracket. The CCD camera 71 is mounted on the sliding bracket. The sliding drive drives the sliding bracket to slide along the length direction of the support fixture 9 at the appearance inspection station. The sliding drive includes, but is not limited to, cylinders, hydraulic rods, electric push rods, etc.

[0070] like Figure 1 As shown, the unloading robot 8 is set up corresponding to the unloading station. The unloading robot 8 is used to transfer the detonator chips on the carrying fixture 9 at the unloading station to the loading fixture 21 on the transport line 2. The unloading robot 8 includes a connected XYZ three-axis moving platform and a picking device. In the actual equipment, the structure of the unloading robot 8 can be the same as that of the loading robot 3.

[0071] To further improve the working efficiency of the heat shrink tubing installation equipment, optionally, the heat shrink tubing installation equipment also includes a replacement mechanism 10. The replacement mechanism 10 includes a replacement table 101 and a replacement robot 102. The replacement table 101 is located on the side of the transport line 2 away from the turntable 1 and is set corresponding to the appearance inspection station. The replacement robot 102 is used to transfer defective products on the carrying fixture 9 at the appearance inspection station to the replacement table 101, and to transfer qualified products on the replacement table 101 to the carrying fixture 9 at the appearance inspection station. The specific structure of the replacement robot 102 can be the same as that of the loading robot 3. Not having a dedicated replacement station on the turntable 1 simplifies the structure of the heat shrink tubing installation equipment, reduces its overall size, further saves time, and improves production efficiency.

[0072] The overall working process of this heat shrink tubing installation equipment is briefly described below:

[0073] The unlocking drive 14 of the corresponding loading station is activated, which unlocks the load-bearing fixture 9 at the loading station. Then, the loading robot 3 takes out the detonator chip from the loading fixture 21 on the lifting mechanism 22 corresponding to the loading station and transfers the taken out detonator chip to the unlocked load-bearing fixture 9 at the loading station. Then, the unlocking drive 14 is reset, and the locking component 93 of the load-bearing fixture 9 locks the plate containing the detonator chip.

[0074] The transmission drive 13 of the turntable 1 drives the load fixture 9 at the loading station to the electrical testing station. The limit drive 41 drives the limit block 42 to move so that the limit block 42 limits the load fixture 9 at the electrical testing station. Then the electrical testing drive drives the electrical testing lifting platform to descend, and the electrical testing terminals contact the detonator chip to perform electrical performance testing.

[0075] After the electrical test is completed, the transmission drive 13 of the turntable 1 drives the carrier fixture 9 at the electrical test station to the sleeve station. After the sleeve station completes its work, the transmission drive 13 of the turntable 1 drives the carrier fixture 9 at the electrical test station to the heat shrink station. The second lifting drive 63 drives the baffle 64 to rise, and the heat shrink drive 61 drives the heat shrink body 62 to approach the carrier fixture 9 at the heat shrink station, so that the heat shrink tube section of the detonator chip is inserted into the opening 65, thereby allowing the heat shrink tube on the detonator chip to complete the heat shrink. The heat shrink drive 61 and the second lifting drive 63 are reset.

[0076] After heat shrinking is completed, the transmission drive 13 of the turntable 1 drives the carrier fixture 9 in the heat shrinking station to the appearance inspection station. The CCD camera 71 takes a picture of a part of the detonator chip on the carrier fixture 9. After the sliding drive drives the sliding bracket to move, the CCD camera 71 takes a picture of another part of the detonator chip on the carrier fixture 9.

[0077] When there are products that fail to meet appearance or electrical test standards, the unlocking drive 14 of the corresponding appearance inspection station is activated, which unlocks the carrier fixture 9 at the appearance inspection station. The replacement mechanism 10 removes the defective product from the carrier fixture 9 at the appearance inspection station and transfers it to the empty space of the loading fixture 21 on the replacement table 101. Then, the replacement mechanism 10 removes the qualified product from the loading fixture 21 on the replacement table 101 and places the qualified product back onto the carrier fixture 9 at the appearance inspection station. Finally, the unlocking drive 14 is activated.

[0078] After the visual inspection is completed, the transmission drive 13 of the turntable 1 drives the carrier fixture 9 at the visual inspection station to the unloading station. The unlocking drive 14 of the unloading station is activated, which unlocks the carrier fixture 9 at the unloading station. Then, the unloading robot 8 takes out the detonator chip with heat shrink tubing installed from the carrier fixture 9 at the loading station and transfers the taken-out detonator chip to the loading fixture 21 on the lifting mechanism 22 corresponding to the unloading station. Finally, the lifting mechanism 22 is reset, so that the loading fixture 21 on the lifting mechanism 22 returns to the transport line 2.

[0079] The above are merely optional embodiments of the present invention and do not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
