Description

Technical Field

[0001] This invention relates to the field of automotive air conditioning clutch manufacturing technology, specifically to an automatic glue-applying equipment for automotive air conditioning clutches. Background Technology

[0002] The automotive air conditioning electromagnetic clutch is a power transmission device between the automotive engine and the automotive air conditioning compressor. The automotive air conditioning compressor is driven by the automotive engine through the electromagnetic clutch. The automotive air conditioning electromagnetic clutch is generally composed of three parts: pulley assembly, coil assembly, and drive plate assembly. The automotive air conditioning electromagnetic clutch is a relatively typical mechatronics product.

[0003] After the coil assembly is installed in the housing, resin glue needs to be injected into the housing to seal the coil assembly. However, during the glue injection process, because there are data cables on the side of the electromagnetic clutch, the data cables lack a positioning structure during the glue injection process. Workers need to bend and arrange them one by one, which affects the installation efficiency of the electromagnetic clutch on the transfer template. At the same time, during the later transfer glue injection process, the data cables will reset and curl up, affecting the glue injection process. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a safety performance testing device for flexible electrical insulation devices, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] An automatic glue-applying device for automotive air conditioning clutches includes a conveyor rail, on the top of which are multiple transfer templates. The surfaces of the transfer templates have rectangularly arranged central tubes used to position and mount the electromagnetic clutch body. The electromagnetic clutch body includes an annular housing with an annular receiving cavity inside. A central hole is located at the center of the annular housing, into which the central tubes are inserted. A data cable is electrically connected to the outer wall of the annular housing, with a connector at the end of the data cable. Multiple retaining seats are located on the surface of the transfer templates, and a retaining seat is located on the side of each central tube. A glue-applying mechanism is mounted on the top surface of the conveyor rail, and a liftable electromagnetic clutch constraint assembly is mounted at the bottom of the glue-applying mechanism.

[0007] The electromagnetic clutch constraint assembly includes an outer frame, an inner plate, a rotation drive assembly, an outer ring assembly, and a rolling assembly. The outer frame is lifted and installed at the bottom of the glue injection mechanism. The outer frame has multiple rectangular slots inside, and each rectangular slot has a set of inner plates. The inner plates have linearly arrayed operating holes inside, and each operating hole has an outer ring assembly around its outer circumference. Each operating hole has a rolling assembly above its upper part, and the rolling assembly is fixed to the inner wall of the outer ring assembly.

[0008] Automatic glue dispensing equipment includes the following states:

[0009] In the first state, the electromagnetic clutch body is inserted into the outside of the corresponding central tube, and the data line end of the electromagnetic clutch body is clipped into the card slot.

[0010] In the second state, the conveyor rail transports the transfer template to the bottom of the outer frame, and each electromagnetic clutch body is correspondingly arranged below the operating hole;

[0011] In the third state, the outer frame descends once, the annular shell passes through the operation hole, and the glue injection mechanism injects resin into the receiving cavity;

[0012] In the fourth state, the outer frame descends a second time, the rolling assembly is inserted into the outer wall of the annular shell, the rolling assembly drives the annular shell to rotate, so that the redundant data line is wound up to the outer wall of the annular shell, and the inner plate stops the data line in the winding state from above.

[0013] In the fifth state, the outer ring assembly drives the rolling assembly to make a circular motion to fully roll the resin liquid in the receiving cavity and discharge the gas in the resin liquid.

[0014] Furthermore, the rolling assembly includes a fixed plate, a fixed column, a rolling plate, a third drive rod, and a positioning rod. The fixed column is vertically provided on the inner side of the bottom surface of the fixed plate, the rolling plate is vertically provided at the bottom end of the fixed column, and a rotation drive assembly is vertically slidably installed on the outer side of the bottom surface of the fixed plate. The third drive rod is provided at the top of the fixed plate and is fixed to the outer ring assembly by the positioning rod.

[0015] In the second state, the third drive rod drives the fixed plate to lift and retract, and the rolling plate is positioned directly above the receiving cavity.

[0016] In the fourth state, the third drive rod drives the fixed plate to move downward, so that the rotation drive assembly contacts the outer wall of the annular shell, and the rolling plate enters the receiving cavity and contacts the resin liquid.

[0017] In the fifth state, the rotation drive assembly does not translate and does not contact the outer wall of the annular housing.

[0018] Furthermore, the bottom surface of the rolling plate is embedded with a ring-shaped array of balls.

[0019] Furthermore, the rotation drive assembly includes a drive column, a drive shaft at the top of the drive column, a constraint ring rotatably fitted on the outer wall of the drive shaft, the constraint ring being placed in a mounting hole in the fixed plate, multiple sets of spring rods on the inner side of the constraint ring, a second motor installed at the top of the drive shaft, and an electromagnet on the outer side of the constraint ring.

[0020] When the electromagnet is energized, it attracts the constraint ring, causing the constraint ring to translate and stretch the spring rod, preventing the drive column from contacting the outer wall of the annular shell. When the electromagnet is de-energized, the spring rod pulls the drive column to retract and contact the outer wall of the annular shell.

[0021] Furthermore, the outer ring assembly includes a toothed ring, constraint posts, a central gear, a drive gear, and a first motor. The toothed ring is concentrically located on the outside of the operating hole and is rotatably mounted on the surface of the inner plate. The outer wall of the toothed ring meshes with the central gear, and the side of the central gear meshes with the drive gear. The first motor is mounted on the bottom of the drive gear. The outer wall of the toothed ring is rolled and fitted against multiple constraint posts, which are vertically located on the surface of the inner plate. A positioning rod is vertically fixed to the top surface of the toothed ring.

[0022] Furthermore, the glue injection mechanism includes a horizontal guide plate and a vertical guide plate. The vertical guide plates are respectively located on both sides of the outer frame. The bottom ends of the vertical guide plates are fixed to the side walls of the conveying track by support columns. A horizontal guide plate is slidably fitted between the two sets of vertical guide plates. A glue box is installed on the surface of the horizontal guide plate. A movable seat is slidably installed on the bottom surface of the horizontal guide plate. A glue pump is installed on the bottom surface of the movable seat. The input end of the glue pump is connected to the glue box. The output end of the glue pump is connected to a vertically downward extending glue injection pipe. The glue injection pipe is located above the receiving cavity. The first drive rod is vertically located in the middle of the bottom surface of the vertical plate.

[0023] Furthermore, the operating hole has a quadrilateral structure, with semi-circular edges at both longitudinal ends and straight edges on both transverse sides; in the third state, the two sets of straight edges are respectively attached to the side wall of the annular shell, and the straight edges of the inner plate are used with data lines in a pressed and wound state; both semi-circular edges at both ends have a movable gap with the annular shell.

[0024] Furthermore, the electromagnetic clutch constraint assembly also includes a moving bar, which is spaced at the longitudinal side of the outer frame. The second drive rod is symmetrically arranged at both ends of the transverse surface of the outer frame. The moving bar is symmetrically provided with mating plates at both ends of its surface. The output end of the second drive rod is connected to the mating plate. The inner wall of the moving bar is provided with multiple guide posts, which are slidably embedded in the outer frame. The inner plate is slidably embedded in the rectangular groove, and the end of the inner plate is fixedly connected to the moving bar.

[0025] In the third state, the second drive rod drives the moving bar to reciprocate longitudinally, and the inner plate moves back and forth and collides with the outer wall of the annular shell to vibrate the resin liquid inside the annular shell.

[0026] Furthermore, the output end of the glue pump is connected in parallel with vertically downward-distributed glue tubes; in the second state, the glue tubes are positioned above the movable gap; in the sixth state, the glue tubes drip resin liquid, which passes through the movable gap below and adheres to the data line in the winding state, so that the data line in the winding state is pre-bonded to the annular shell as a whole.

[0027] Furthermore, the central tube includes a lower tube body and an upper tube body. The lower tube body is vertically connected to the surface of the substrate. The top of the lower tube body is provided with an upper tube body with a horn structure. The outer wall of the upper tube body is provided with a convex ring, and the outer wall of the convex ring is attached to the inner wall of the assembly hole. An exhaust fan is provided at one end of the surface of the transfer template, and the exhaust fan is connected to each lower tube body. The outer wall of the upper tube body has an air inlet holes distributed in a ring array. In the third state, the exhaust fan works to generate negative pressure at the upper tube body to absorb the odor generated by the resin adhesive in a ring.

[0028] This invention provides an automatic glue-applying device for automotive air conditioning clutches. Compared with the prior art, it has the following advantages:

[0029] Beneficial effects:

[0030] 1. The card slot can pre-position the data cable, making it convenient for staff to quickly install the electromagnetic clutch and lay the data cable without having to manage the cable, thus preventing the data cable and connector from shifting or becoming loose.

[0052] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are described clearly and completely. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0053] Example 1

[0054] To address the technical problems in the background art, the following embodiments are provided:

[0055] Combination Figures 1-17As shown, the automatic glue-filling device for automotive air conditioning clutches provided by the present invention includes a conveying track 1, a plurality of transfer templates 2 placed on the top of the conveying track 1, and a rectangular array of central tubes 22 distributed on the surface of the transfer templates 2. The central tubes 22 are used to mount and position the electromagnetic clutch body 3. The electromagnetic clutch body 3 includes an annular housing 31, an annular receiving cavity 311 is opened inside the annular housing 31, and a central hole is installed at the center of the annular housing 31. The central tubes 22 are inserted into the central hole. The outer wall of the annular housing 31 is electrically connected to a data cable 32, and the end of the data cable 32 is provided with a connector 33. A plurality of card seats 21 are provided on the surface of the transfer templates 2, and a card seat 21 is provided on the side of each central tube 22. A glue-filling mechanism 5 is installed on the top surface of the conveying track 1, and a liftable electromagnetic clutch constraint assembly 6 is installed at the bottom of the glue-filling mechanism 5.

[0056] The electromagnetic clutch constraint assembly 6 includes an outer frame 61, an inner plate 66, a rotation drive assembly 72, an outer ring assembly 63, and a rolling assembly 7. The outer frame 61 is lifted and installed at the bottom of the glue injection mechanism 5. The outer frame 61 has multiple rectangular slots 611 inside, and each rectangular slot 611 is provided with a set of inner plates 66. The inner plates 66 have linearly arrayed operating holes 661 inside, and each operating hole 661 has a set of outer ring assemblies 63 around its outer ring. Each operating hole 661 has a set of rolling assemblies 7 above its upper edge, and the rolling assemblies 7 are fixed to the inner wall of the outer ring assembly 63.

[0057] The automatic glue dispensing equipment includes the following states: In the first state, the electromagnetic clutch body 3 is inserted into the outside of the corresponding central tube 22, and the end of the data line 32 of the electromagnetic clutch body 3 is clamped in the card holder 21; In the second state, the conveying track 1 conveys the transfer template 2 to the underside of the outer frame 61, and each electromagnetic clutch body 3 is correspondingly arranged under the operating hole 661; In the third state, the outer frame 61 descends once, the annular shell 31 passes through the operating hole 661, and the glue dispensing mechanism 5 injects resin glue into the receiving cavity 311; In the fourth state, the outer frame 61 descends a second time, the rolling assembly 7 is inserted into the outer wall of the annular shell 31, the rolling assembly 7 drives the annular shell 31 to rotate, so that the redundant data line 32 is wound to the outer wall of the annular shell 31, and the inner plate 66 stops the data line 32 from the top; In the fifth state, the outer ring assembly 63 drives the rolling assembly 7 to make a circular motion to fully roll the resin glue in the receiving cavity 311 and discharge the gas in the resin glue.

[0058] In the above scheme,

[0059] 1. The card holder 21 can pre-position the data cable 32, which makes it convenient for staff to quickly install the electromagnetic clutch and lay the data cable 32 without having to sort the cable, thus preventing the data cable 32 and connector 33 from shifting or becoming loose.

[0060] 2. The design of the rolling assembly 7 can achieve the following effects: 2.1. The rolling assembly 7 can roll and inject resin liquid, thereby squeezing out the gas in the resin liquid to ensure the compactness of the resin liquid; 2.2. The rolling assembly 7 can drive the internal electromagnetic clutch to rotate. When the electromagnetic clutch rotates, it can drive the redundant data line 32 to rotate, thus realizing the automatic winding and positioning of the data line 32, eliminating the need for subsequent winding and positioning.

[0061] 3. The rolling assembly 7 can switch its operation. When winding, it contacts the annular housing 31. When rolling, the rolling assembly 7 does not contact the annular housing 31. The outer ring assembly 63 can drive the rolling assembly 7 to rotate so that the rolling assembly 7 squeezes the resin.

[0062] In this embodiment, the rolling assembly 7 includes a fixing plate 71, a fixing post 732, a rolling plate 73, a third drive rod 74, and a positioning rod 75. The fixing post 732 is vertically provided on the inner side of the bottom surface of the fixing plate 71, and the rolling plate 73 is vertically provided at the bottom end of the fixing post 732. The rotation drive assembly 72 is vertically slidably installed on the outer side of the bottom surface of the fixing plate 71, and the third drive rod 74 is provided at the top of the fixing plate 71. The third drive rod 74 is fixed to the outer ring assembly 63 by the positioning rod 75.

[0063] In the second state, the third drive rod 74 drives the fixed plate 71 to lift and retract, and the rolling plate 73 is positioned directly above the receiving cavity 311. In the fourth state, the third drive rod 74 drives the fixed plate 71 to move downward, so that the rotation drive assembly 72 contacts the outer wall of the annular housing 31, and the rolling plate 73 enters the receiving cavity 311 and contacts the resin. In the fifth state, the rotation drive assembly 72 translates and does not contact the outer wall of the annular housing 31.

[0064] In the above scheme, the third drive rod 74 can drive the rolling plate 73 and the rotation drive assembly 72 to retract upwards, so that the receiving cavity 311 is exposed and the adhesive can be output into the receiving cavity 311; the third drive rod 74 can drive the rolling plate 73 and the rotation drive assembly 72 to descend, so that the rotation drive assembly 72 fits against the outer wall of the annular shell 31 and the rolling plate 73 is embedded in the receiving cavity 311.

[0065] In this embodiment, the bottom surface of the rolling plate 73 is embedded with a ring array of balls 731.

[0066] In the above scheme, the distributed ball bearings 731 can achieve dot matrix extrusion, so that the gas is discharged from the gaps between the ball bearings 731, resulting in a better extrusion effect.

[0067] In this embodiment, the rotation drive assembly 72 includes a drive column 721, a transmission shaft 7211 at the top of the drive column 721, a constraint ring 723 rotatably fitted on the outer wall of the transmission shaft 7211, the constraint ring 723 being translated into a mounting hole in the fixing plate 71, multiple sets of spring rods 725 on the inner side of the constraint ring 723, a second motor 722 mounted at the top of the transmission shaft 7211, and an electromagnet 724 on the outer side of the constraint ring 723. When the electromagnet 724 is energized, it attracts the constraint ring 723, causing the constraint ring 723 to translate and stretch the spring rods 725, preventing the drive column 721 from contacting the outer wall of the annular housing 31. When the electromagnet 724 is de-energized, the spring rods 725 pull the drive column 721 to retract and contact the outer wall of the annular housing 31.

[0068] In the above scheme,

[0069] During the winding stage, since the length of the redundant data line 32 is not fixed, the annular housing 31 cannot rotate a full circle, but only needs to rotate a certain angle. Therefore, the drive column 721 is driven to work.

[0070] By engaging the electromagnet 724 with the constraint ring 723, the driving column 721 can be translated to meet the processing requirements of rolling and winding.

[0071] In this embodiment, the outer ring assembly 63 includes a toothed ring 631, constraint posts 632, a central gear 633, a drive gear 634, and a first motor 6341. The toothed ring 631 is concentrically disposed on the outside of the operating hole 661. The toothed ring 631 is rotatably mounted on the surface of the inner plate 66. The outer wall of the toothed ring 631 is meshed with the central gear 633. The side of the central gear 633 is meshed with the drive gear 634. The first motor 6341 is mounted on the bottom of the drive gear 634. The outer wall of the toothed ring 631 is rolled and fitted against multiple constraint posts 632. The constraint posts 632 are vertically disposed on the surface of the inner plate 66. The positioning rod 75 is vertically fixed to the top surface of the toothed ring 631.

[0072] In the above scheme, the first motor 6341 drives the drive gear 634 to rotate, which can drive the gear ring 631 to rotate through the intermediate gear 633. When the gear ring 631 rotates, it can drive the rolling assembly 7 to rotate, so that the rolling assembly 7 can rotate a full circle.

[0073] In this embodiment, the glue injection mechanism 5 includes a horizontal guide plate 51 and a vertical guide plate 54. The vertical guide plate 54 is respectively disposed on both sides of the outer frame 61. The bottom ends of the vertical guide plate 54 are fixed to the side wall of the conveying track 1 by support columns 541. The horizontal guide plate 51 is slidably fitted between the two sets of vertical guide plates 54. A glue box 52 is installed on the surface of the horizontal guide plate 51. A movable seat 53 is slidably installed on the bottom surface of the horizontal guide plate 51. A glue pump 55 is installed on the bottom surface of the movable seat 53. The input end of the glue pump 55 is connected to the glue box 52. The output end of the glue pump 55 is connected to a vertically downward extending glue injection pipe 56. The glue injection pipe 56 is located above the receiving cavity 311. The first drive rod 62 is vertically disposed in the middle of the bottom surface of the vertical plate.

[0074] In the above scheme, the horizontal guide plate 51 can be moved along the vertical guide plate 54, and the moving seat 53 can be moved laterally along the horizontal guide plate 51, so that the glue injection tube 56 can automatically inject glue into the electromagnetic clutch one by one.

[0075] In this embodiment, the operation hole 661 is a quadrilateral structure, with the two longitudinal ends of the operation hole 661 being semi-circular edges and the two transverse sides of the operation hole 661 being straight edges; in the third state, the two sets of straight edges are respectively attached to the side wall of the annular shell 31, and the straight edges of the inner plate 66 are wrapped with data lines 32 in a pressed state; the semi-circular edges at both ends are left with a movable gap with the annular shell 31.

[0076] In the above scheme, the operating hole 661 adopts the above structure, with semi-circular edges at both ends, which can leave a movable gap between it and the annular shell 31. The movable gap can ensure that the resin can be shaken flat when vibrating. At the same time, during subsequent glue dispensing, the movable gap can serve as a through area for the resin to ensure that the glue can adhere to the data cable 32 in the winding state.

[0077] In this embodiment, the electromagnetic clutch constraint assembly 6 further includes a movable strip 64, which is spaced apart on the longitudinal side of the outer frame 61. The second drive rod 65 is symmetrically arranged at both ends of the surface of the outer frame 61. The two ends of the surface of the movable strip 64 are symmetrically provided with mating plates 642. The output end of the second drive rod 65 is connected to the mating plate 642. The inner wall of the movable strip 64 is provided with a plurality of guide posts 641. The guide posts 641 are slidably embedded in the outer frame 61. The inner plate 66 is slidably embedded in the rectangular groove 611. The end of the inner plate 66 is fixedly connected to the movable strip 64.

[0078] In the third state, the second drive rod 65 drives the moving bar 64 to reciprocate longitudinally, and the inner plate 66 reciprocates and collides with the outer wall of the annular shell 31 to vibrate the resin liquid inside the annular shell 31.

[0079] In the above scheme, the second drive rod 65 can drive the moving bar 64 to reciprocate. The moving bar 64 can drive the inner plate 66 to reciprocate along the side support plate 612 of the inner wall of the rectangular groove 611. The semi-circular edge of the operation hole 661 can collide with the annular shell 31 to vibrate the annular shell 31, so that the newly injected adhesive is leveled.

[0080] In this embodiment, the output end of the glue pump 55 is connected in parallel with vertically downward distributed glue dispensing tubes 57; in the second state, the glue dispensing tubes 57 are positioned opposite each other above the movable gap; in the sixth state, the glue dispensing tubes 57 drip resin glue, the dripped resin glue passes through the movable gap below and adheres to the data cable 32 in the winding state, so that the data cable 32 in the winding state is pre-bonded to the annular housing 31 as a whole.

[0081] In the above solution, if the electromagnetic clutch is removed directly during winding, the pre-wound data cable 32 may still become loose. Therefore, by dripping resin liquid into the drip tube 57, the data cable 32 in the winding state can be pre-positioned. In this way, when it is removed, the data cable 32 will not become loose and can be directly packaged into a box. When in use, the data cable 32 can be loosened by simply pulling it down slightly.

[0082] In this embodiment, the central tube 22 includes a lower tube 221 and an upper tube 222. The lower tube 221 is vertically connected to the surface of the substrate. The top of the lower tube 221 is provided with an upper tube 222 of a horn structure. The outer wall of the upper tube 222 is provided with a protruding ring 223, and the outer wall of the protruding ring 223 is attached to the inner wall of the assembly hole 312. One end of the surface of the transfer template 2 is provided with an exhaust fan 4, which is connected to each lower tube 221. The outer wall of the upper tube 222 has an air inlet holes 2221 arranged in a ring array. In the third state, the exhaust fan 4 works to generate a negative pressure at the upper tube 222 to absorb the odor generated by the resin adhesive in a ring.

[0083] In the above scheme, the central tube 22 can not only support the electromagnetic clutch from the inside, but also absorb adhesive gas in a ring during the glue injection stage, reducing odor in the processing area.
