Description

Technical Field

[0001] This utility model relates to a device for trimming and cutting the leads of cement resistors, and more particularly to a transmission device for a high-efficiency fully automatic cement resistor lead trimming, testing and cutting integrated machine, belonging to the technical field of electrical component processing equipment. Background Technology

[0002] Cement resistors are resistors encapsulated in refractory clay. During manufacturing, resistance wire is wound around an alkali-free, heat-resistant ceramic core, which is then protected and secured with heat-resistant, moisture-resistant, and corrosion-resistant materials. The wire-wound resistor is placed within a square ceramic frame and sealed with special non-flammable, heat-resistant cement. After sealing, some cement resistors require lead trimming, testing, and cutting of excess leads before packaging and shipping. Currently, lead trimming and cutting of cement resistors are mostly done manually, which is labor-intensive, inefficient, and the consistency of lead cutting is greatly affected by human factors, thus impacting the final quality of the cement resistor.

[0018] The transfer mechanism 5 is located on the top left side of the rack electrical box 1, corresponding to the position of the integrated foot-shearing mechanism 4 for the full-foot test. The transfer mechanism 5 includes a support frame 51, a pair of slide rails 52, a transfer cylinder 53, a moving frame 54, a top plate 55, a lifting cylinder 56, ten gripper assemblies 57, and a top plate cover 58. The support frame 51 is fixedly supported on the top of the rack electrical box 1. The pair of slide rails 52 are horizontally parallel on both sides of the top of the support frame 51. The bottom sides of the moving frame 54 are slidably supported on the pair of slide rails 52. The transfer cylinder 53 is fixed to the bottom of the support frame 51, and the bottom of the moving frame 54 is fixedly connected to the support plate on the piston rod of the transfer cylinder 53. The top plate 55 is located on the upper side of the moving frame 54, and the sliders at both ends of the bottom of the top plate 55 are slidably supported on the vertical guide rails at both ends of the moving frame 54. The lifting cylinder 56 is vertically fixed to the center of the base plate of the moving frame 54 by fasteners, and the piston rod of the lifting cylinder 56 is fixedly connected to the bottom of the top plate 55. Ten gripper assemblies 57 are fixed at intervals on the top plate 55.

The top plate 55 is also equipped with a defective product sorting gripper assembly, for a total of eleven gripper assemblies. The top plate cover 58 covers the eleven gripper assemblies 57.

[0019] The material pushing assembly 7 is located on the front left side of the material rack 2, corresponding to the left end of the recycling tray 8. The recycling tray 8 is longitudinally fixed to the front side of the material rack 2. The material pushing assembly 7 includes a material pushing cylinder 71 and an inverted L-shaped material pushing plate 72. The material pushing cylinder 71 is fixed to the front left side of the material rack 2 by fasteners. The lower end of the vertical edge of the inverted L-shaped material pushing plate 72 is fixed to the piston rod of the material pushing cylinder 71, and the horizontal edge of the inverted L-shaped material pushing plate 72 corresponds to the left end of the recycling tray 8. A retaining edge 81 is provided on the outer side of the recycling tray 8 to prevent the cement resistor 10 from scattering.

[0020] The working process of this utility model is as follows:

[0021] The cement resistor 10 is manually placed on the feeding platform 31. Under the vibration of the direct vibrator 33, the cement resistor 10 moves to the feeding station 321 of the feeding tray 32. After the feeding sensor detects the cement resistor 10, the top plate 55 of the transfer mechanism 5 is lifted by the lifting cylinder 56. At the same time, the moving frame 54 moves the top plate 55 to the right to the feeding station 321 under the action of the transfer cylinder 53. The top plate 55 descends, and the first gripper assembly 57 at its right end grabs the cement resistor 10. The top plate 55 is lifted again and moved to the left to the first alignment station. The top plate 55 descends, placing the cement resistor 10 in the first alignment station. The first alignment assembly 43 can then perform left and right alignment on the cement resistor 10. Similarly, the second gripper assembly 57 at the right end of the top plate 55 can grab the cement resistor 10 from the first alignment station and place it in the second alignment station. The second alignment assembly 44 can then perform up and down alignment on the cement resistor 10.

[0022] Similarly, the moving frame 54 moves back and forth left and right, while the top plate 55 moves up and down back and forth. The corresponding gripper assembly 57 can quickly transport the cement resistor 10 to the next processing station. The cement resistor 10 can be subjected to withstand voltage test, two resistance value test, cut off the lead, and then be adjusted up and down and left and right again by the withstand voltage test assembly 45, the first resistance value test assembly 46, the second resistance value test assembly 47, the lead shearing assembly 48, the third lead straightening assembly 49 and the fourth lead straightening assembly 40 in sequence, thereby completing all processing steps.

[0023] After all processing steps are completed, the gripper assembly 57 at the leftmost end of the top plate 55 grabs the cement resistor 10 and places it on the rear end of the feeding conveyor belt 6. The cement resistor 10 moves to the front end through the feeding conveyor belt 6 and is blocked by the side rail 81 of the recycling tray 8. At this time, the piston rod of the pushing cylinder 71 retracts, and the horizontal edge of the inverted L-shaped pushing plate 72 pushes the cement resistor 10 into the recycling tray 8 in sequence for neat arrangement, which is convenient for packing.

[0024] In addition to the above embodiments, the present invention may have other implementation methods. All technical solutions formed by equivalent substitution or equivalent transformation fall within the protection scope claimed by the present invention.
