Description

TECHNICAL FIELD

[0001] The utility model relates to the field of resistance sheet production technology, specifically to a multi-station weighing conveying mechanism. BACKGROUND

[0002] In the current resistance sheet production process, the performance and quality of the resistance sheet are the key elements for its application in various electronic devices. Among them, the surface paint spraying treatment of the resistance sheet as an important link in the production process not only concerns the appearance beauty of the resistance sheet, but also directly affects its key characteristics such as moisture-proof, corrosion-resistant and insulating performance. The paint spraying treatment aims to enhance the environmental adaptability and service life of the resistance sheet by uniformly covering a layer of protective paint.

[0003] However, in the actual production process, although advanced paint spraying equipment and control technology are used, due to various factors such as the accuracy of the paint spraying equipment, the setting of the paint spraying parameters, the slight differences on the surface of the resistance sheet and the experience level of the operators, etc., the paint amount on the surface of the resistance sheet after paint spraying often cannot be completely consistent. This unevenness of the paint amount may affect the electrical performance of the resistance sheet, such as increasing unnecessary resistance value changes, and even in some extreme cases, it may cause the resistance sheet to fail to function. Based on this, we propose a multi-station weighing conveying mechanism, which can weigh the resistance sheet before and after paint spraying to determine whether the paint amount on the surface of the resistance sheet meets the requirements. SUMMARY

[0010] Furthermore, the servo conveying device includes a bracket mounted on the upper part of the base plate, a servo drive module mounted on the top of the bracket, and a movable seat mounted on the drive end of the movable seat.

[0013] Furthermore, the positioning device includes linear guide rails symmetrically mounted on the upper part of the base plate and a double-headed telescopic cylinder mounted on the bottom of the inner part of the base plate.

The top ends of the first linkage frame and the second linkage frame are respectively equipped with a first positioning plate and a second positioning plate. The adjacent end faces of the first positioning plate and the second positioning plate are provided with a plurality of positioning grooves.

[0016] Beneficial effects:

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0024] Please refer to Figures 1-4 The utility model provides a kind of technical solutions: a multi-station weighing conveying mechanism is composed of bottom plate 1, first weighing area 2, second weighing area 3, twelve weighing stations 4, twelve weighing sensors 5, servo conveying device 6 and two sets of positioning devices 7, wherein, first weighing area 2, second weighing area 3 are all set in the upper portion of bottom plate 1, twelve weighing stations 4 and twelve weighing sensors 5 are divided into two groups, and weighing sensor 5 is all installed on weighing station 4, wherein six weighing stations 4 and six weighing sensors 5 are located in first weighing area 2, another six weighing stations 4 and six weighing sensors 5 are located in second weighing area 3, six weighing sensors 5 in first weighing area 2 can weigh six resistance sheets without painting, similarly, another six weighing sensors 5 in second weighing area 3 can weigh six resistance sheets after painting, so that the weight of each resistance sheet before and after painting can be known, and then whether the paint on the surface of resistance sheet is overweight or not, whether it meets quality standard or not can be known, servo conveying device 6 can simultaneously suction six resistance sheets to be painted from first weighing area 2 and convey to painting station (not shown in the figure), similarly, six resistance sheets after painting can also be conveyed from painting station and placed on six weighing sensors 5 in second weighing area 3, two sets of positioning devices 7 are located in the upper portion of first weighing area 2, position resistance sheet when placed manually, prevent the problem of position deviation of resistance sheet when placed manually, so as to lay a foundation for subsequent pickup of servo conveying device 6;

[0025] In addition, the servo conveying device 6 includes a bracket 61 installed on the upper part of the base plate 1. A servo drive module 62 is installed on the top of the bracket 61 (the servo drive module 62 adopts existing technology, and its specific structure and working principle are existing known technologies, which will not be described in detail here). The drive end of the movable seat 63 is equipped with a movable seat 63. The bottom end of the movable seat 63 is equipped with a lifting drive cylinder 64. The telescopic end of the lifting drive cylinder 64 is equipped with a nozzle mounting seat 65. The nozzle mounting seat 65 has an "I" shaped structure, and six suction nozzles 66 are installed inside the nozzle mounting seat 65. All six suction nozzles 66 are connected to an external negative pressure device (not shown in the figure) through air pipes.

[0026] When the servo conveying device 6 is working, the servo drive module 62 drives the six suction nozzles 66 to move back and forth between the first weighing zone 2, the second weighing zone 3 and the painting station. When the six suction nozzles 66 are directly above the first weighing zone 2, the lifting drive cylinder 64 pushes the nozzle mounting base 65 down, so that the six suction nozzles 66 simultaneously pick up the six resistor sheets and then convey them to the painting station. Similarly, the resistor sheets after painting are also transported from the painting station to the second weighing zone 3 in the same way.

[0027] The positioning device 7 includes a linear guide rail 71 symmetrically installed on the upper part of the base plate 1 and a double-headed telescopic cylinder 72 installed at the bottom inside the base plate 1. The two telescopic ends of the double-headed telescopic cylinder 72 are respectively connected to a first linkage frame 73 and a second linkage frame 74. The top ends of the first linkage frame 73 and the second linkage frame 74 are respectively equipped with a first positioning plate 75 and a second positioning plate 76. The adjacent end faces of the first positioning plate 75 and the second positioning plate 76 are provided with a plurality of positioning grooves 77. The first positioning plate 75 and the second positioning plate 76 are slidably arranged on the upper part of the linear guide rail 71.

[0028] When the positioning device 7 is working, before the operator places the resistive sheet, the two telescopic ends of the double-headed telescopic cylinder 72 retract simultaneously, thereby driving the first linkage frame 73 and the second linkage frame 74 to move closer, so that the first positioning plate 75 and the second positioning plate 76 move closer and make contact simultaneously. After contact, the diamond-shaped positioning groove 77 is located directly above the center of the load cell 5. At this time, the operator can directly place the resistive sheet inside the positioning groove 77 and let it fall on the load cell 5, and wait for the servo conveying device 6 to pick up the resistive sheet to be painted.

[0029] Finally, the base plate 1 has eight reserved holes 101 inside, which correspond to the first linkage frame 73 and the second linkage frame 74 respectively. In other words, the first linkage frame 73 and the second linkage frame 74 can move inside the reserved holes 101, leaving enough space for the first linkage frame 73 and the second linkage frame 74 to move closer and further away.
