[0047] In the field of chip soldering technology, soldering furnaces are a key piece of equipment. They provide a heating environment to melt solder paste, thereby achieving a reliable bond between surface mount components and PCB pads. However, the current solder paste transportation structure mostly uses long poles for transport. During transportation, due to the influence of its own weight, the middle part of the long pole is prone to sagging, which affects the stability of solder paste delivery.

[0048] This utility model proposes a handling mechanism.

[0049] Please refer to Figures 1 and 4. In one embodiment of this utility model, the conveying mechanism includes:

[0050] The load-bearing component 100 includes a support base 110 and multiple load-bearing ropes 120. The multiple load-bearing ropes 120 are arranged in parallel and spaced apart, and each load-bearing rope 120 is connected to a support base 110 at both ends. The load-bearing ropes 120 are used to carry materials.

[0051] Tensioning assembly 200, disposed on the support base 110, is connected to the load-bearing rope 120 for tensioning the load-bearing rope 120; and

[0052] The first drive component 300 is driven to the load-bearing component 100 to drive the load-bearing component 100 to move along the length direction of the load-bearing rope 120.

[0053] In this utility model, a load-bearing rope 120 is used to carry materials, and both ends of the load-bearing rope 120 are respectively installed on a support base 110. A tensioning component 200 is provided on the support base 110, which keeps the load-bearing rope 120 taut. This makes the materials carried by the load-bearing rope 120 more stable during transportation. The first drive component 300 drives the load-bearing component 100 to move horizontally, which is equivalent to moving the materials horizontally, thus completing the material handling process. Compared with the traditional long pole material transportation, the structure in this embodiment solves the problem of the long pole sagging in the middle due to gravity when transporting materials through the cooperation of the load-bearing rope 120 and the tensioning component 200. Since the tensioning component 200 can adjust the tension of the load-bearing rope 120 in real time, the load-bearing rope 120 can maintain a suitable tension at any time, so that the materials remain stable during transportation, avoiding swaying and instability caused by sagging, and improving the safety and reliability of the handling process.

[0054] The load-bearing component 100 includes a support base 110 and load-bearing ropes 120. Two support bases 110 are provided and positioned opposite each other. Multiple load-bearing ropes 120 are connected between the two support bases 110, spaced apart. The load-bearing ropes 120 are used to support the frame and other carriers. Solder paste is placed inside the frame. Both ends of the load-bearing ropes 120 are mounted on the support bases 110 and tensioned by a tensioning component 200. This ensures uniform force on the material during transportation and allows for real-time adjustment of the tension of the load-bearing ropes 120 according to the weight of the material. The load-bearing rope 120 is kept at an appropriate tension at all times. In one embodiment, the load-bearing rope 120 is made of steel wire rope. Steel wire rope has high tensile strength and can withstand high loads. With the cooperation of the tensioning component 200, it can adapt to materials of different weights and shapes and is also suitable for long-distance transportation. Moreover, steel wire has low cost, which can reduce maintenance costs. The first drive component 300 drives the load-bearing component 100 to move. The first drive component 300 can adopt a linear movement structure such as a linear module. There are no restrictions on the structure of the first drive component 300.

[0055] In an embodiment of this utility model, the tensioning assembly 200 includes:

[0056] Two mounting bases 210 are provided, with one mounting base 210 corresponding to each of the support bases 110;

[0057] Tensioner pulley assembly 220 is provided on each of the mounting bases 210, and the two ends of the load-bearing rope 120 are respectively wound around the tensioner pulley assembly 220;

[0058] A tension spring 230 is mounted on any support 110. One end of the tension spring 230 is fixedly connected to the mounting base 210, and the other end is connected to the tension wheel assembly 220.

[0059] Referring to Figures 5 and 6, the tensioning assembly 200 includes a mounting base 210, which is correspondingly mounted on the support base 110. Tensioning wheel sets 220 are correspondingly mounted on the mounting base 210. Each tensioning wheel set 220 has multiple tensioning wheels, and the tensioning wheels of two sets 220 correspond one-to-one. Both ends of each load-bearing rope 120 are connected to the tensioning wheels of two sets 220 respectively. One end of the load-bearing rope 120 is fixedly connected to the tensioning wheel of one set of tensioning wheel sets 220, and the other end is wound around the tensioning wheel of the other set of tensioning wheel sets 220. A tension spring 230 is also connected to the end of the load-bearing rope 120 wound around the tensioning wheel. The other end of the tension spring 230 is fixedly connected to the mounting base 210, and the tension spring 230 is connected to the mounting base 210 and the load-bearing wheel through hooks or other structures. The connection of rope 120 and the setting of the tensioning wheel allow the load-bearing rope 120 to move more smoothly, reducing friction from stretching and shortening. Through the elastic action of the tension spring 230, the tensioning assembly 200 can automatically adjust the tension according to the change in the weight of the material on the load-bearing rope 120, ensuring that the load-bearing rope 120 always maintains a suitable tension. When the weight of the material carried on the load-bearing rope 120 increases, the tension on the load-bearing rope 120 increases, and the tension spring 230 is stretched. Due to the reverse tension of the tension spring 230, the load-bearing rope 120 can be tightened, preventing the load-bearing rope 120 from slack. The mounting base 210 provides stable support for the tensioning wheel assembly 220 and the tension spring 230, avoiding displacement due to external vibration or other external forces during transportation, and ensuring the overall stability of the transportation mechanism.

[0060] In an embodiment of this utility model, the conveying mechanism further includes a mounting plate 400, which is disposed below the load-bearing rope 120. The mounting plate 400 is provided with a heating element, which is used to heat the material on the load-bearing rope 120.

[0061] Please refer to Figure 1. The mounting plate 400 is set below the load-bearing rope 120 and fixed on the frame of the whole machine (not shown). The length direction of the mounting plate 400 is the same as the length direction of the load-bearing rope 120. A heating element is provided on the mounting plate 400. The heating element can heat the solder paste on the frame of the load-bearing rope 120 during the handling process, ensuring that the solder paste maintains good fluidity during transportation, which is convenient for subsequent soldering processes.

[0062] It should be noted that when the load-bearing rope is heated on the load-bearing frame, it is sent to the plate furnace for heating. During the heating process, nitrogen is continuously introduced into the plate furnace to ensure that it is fully heated under an inert gas environment, thus preventing oxygen and other substances from reacting during the heating process. The mounting plate 400 is essentially the bottom cover of the entire plate furnace. That is, the heating element waits on the bottom cover for the frame to be heated and the solder paste is melted to complete the soldering.

[0063] In an embodiment of this utility model, multiple heating elements are provided, and the multiple heating elements are spaced apart along the length direction of the load-bearing rope 120, with each heating element having a different temperature.

[0064] Specifically, by setting multiple heating elements along the length of the 120-meter load-bearing rope, with each element having a different temperature, the heating requirements of the solder paste at different stages of transportation can be met. For example, at the beginning of the solder paste handling process, a higher temperature can be set to quickly raise the material temperature. In the latter half, the temperature can be appropriately reduced to maintain the stability and fluidity of the solder paste. Different temperatures can also be adjusted according to actual production needs, such as setting a temperature gradient according to the transportation direction or cooling the material. The heating elements can be ceramic heating elements, graphene heating films, etc., which can provide heating efficiency and thermal stability.

[0065] In one embodiment, the heating element can also be configured as an independent intelligent temperature control device to adjust the temperature of each heating element in real time according to the production process.

[0066] In an embodiment of this utility model, the conveying mechanism further includes:

[0067] Two connecting seats 500 are provided, with each of the support seats 110 corresponding to one connecting seat 500;

[0068] Connector 510 connects the two support bases 110.

[0069] Referring to Figure 1, two connecting seats 500 are arranged opposite each other, and each support seat 110 is installed on one connecting seat 500. A connector 510 is provided between the two support seats 110, so that the two connecting seats 500 and the two support seats 110 are integrated and can move synchronously in the horizontal direction. That is, the load-bearing component 100 is driven to move in the horizontal direction by the first drive component 300, which improves the stability of the material handling process. The connector 510 can be made of high-strength materials such as aluminum alloy or steel to withstand various external forces during the handling process.

[0070] In an embodiment of the present invention, the conveying mechanism further includes a second drive component 600, which is disposed on at least one of the connecting seats 500 and is drivenly connected to the support seat 110 to drive the support seat 110 to rise and fall.

[0071] Referring to Figure 1, the second drive assembly 600 is mounted on a connecting seat 500 and drives the support seat 110 and the load-bearing rope 120 to rise and fall. This allows the material on the load-bearing rope 120 to move closer to the heating element when it moves to the heating element, in cooperation with the first drive assembly 300 and the second drive assembly 600. When it moves away from the heating element, that is, between the two heating elements, it drives the load-bearing rope 120 and the frame to rise. This not only effectively heats the material but also prevents the load-bearing rope 120 from constantly contacting the mounting plate 400 when it carries the frame, thus avoiding damage caused by friction between the load-bearing rope 120 and the mounting plate 400 during the translation process.

[0072] In one embodiment, the mounting plate 400 is provided with a plurality of through slots, each extending along the length of the load-bearing rope 120. When the second drive assembly drives the support base 110 to lower the load-bearing rope 120 closer to the heating element, the load-bearing rope 120 falls into the through slot of the mounting plate, so that the frame can just contact the heating element on the mounting plate 400, avoiding the load-bearing rope 120 blocking the contact in the middle. When the heating time is sufficient, the load-bearing rope 120 rises and drives the frame away from the heating element. Under the drive of the first drive assembly 300, the frame contacts the next heating element and performs heating and welding at different temperatures.

[0073] In an embodiment of this utility model, the second driving component 600 includes:

[0074] The rotating shaft 610 is rotatably connected to two connecting seats 500 at both ends;

[0075] Two eccentric wheels 620 are provided, and the two eccentric wheels 620 are respectively located at both ends of the rotating shaft 610. The centers of the two eccentric wheels 620 are offset from the rotation center of the rotating shaft 610. The support base 110 abuts against the outer peripheral wall of the eccentric wheel 620.

[0076] The first motor 630 is mounted on any of the connecting seats 500 and is drivenly connected to the rotating shaft 610.

[0077] Referring to Figures 2 and 3, the second drive assembly 600 includes a rotating shaft 610 extending along the length of the load-bearing rope 120, and eccentric wheels 620 disposed at both ends of the rotating shaft 610. A first motor 630 is disposed on one of the connecting seats 500. The output shaft of the first motor 630 is connected to a roller 650 via a belt drive. The roller 650 is coaxially connected to one end of the rotating shaft 610. That is, the first motor 630 drives the roller 650 and the rotating shaft 610 to rotate via the belt. The rotating shaft 610 drives the eccentric wheel 620 to rotate. Since the outer circumference of the eccentric wheel 620 abuts against the bottom of the support seat 110, as the eccentric wheel 620 rotates, the support seat 110 completes vertical displacement, that is, a repetitive action of rising-falling-rising. This facilitates the material on the load-bearing rope 120 to fall for heating when it reaches the heating element, and rise after passing the heating element, reducing friction caused by contact with the mounting plate 400.

[0078] In an embodiment of this utility model, the second drive assembly 600 further includes an elastic element 640, and the support seat 110 and the connecting seat 500 are elastically connected through the elastic element 640 so that the support seat 110 abuts against the outer peripheral wall of the eccentric wheel 620.

[0079] Referring to Figures 2 and 3, a vertically extending connecting shaft is provided between the upper and lower inner walls of the connecting seat 500. The support seat 110 passes through the connecting shaft and moves up and down along the connecting shaft. An elastic element 640 is provided between the top of the support seat 110 and the top inner wall of the connecting seat 500. The elastic element 640 is in a compressed state, which makes the support seat 110 tend to move downward, thus driving the support seat 110 to always abut against the eccentric wheel 620 below, ensuring that the support seat 110 can smoothly follow the movement of the eccentric wheel 620 to achieve precise lifting and lowering during the rotation of the eccentric wheel 620.

[0080] In an embodiment of this utility model, the first driving component 300 includes:

[0081] A bearing housing on which the rotating shaft is rotatably mounted;

[0082] A translation module is driven to the bearing housing, and the translation module drives the bearing housing to move axially along the rotation axis.

[0083] Referring to Figure 1, the first drive assembly 300 includes a translation module and a bearing housing 310. The translation module can be a linear module or a ball screw, etc. Linear modules and ball screws are conventional structures and will not be described in detail here. The structure of the translation module is not limited. The output end of the translation module drives the bearing housing 310. The rotating shaft 610 rotatably passes through the bearing housing 310. When the translation module drives the bearing housing 310 to move, it also drives the rotating shaft 610 to move. The rotating shaft 610 connects two connecting seats 500, thus realizing the translation of the material on the load-bearing rope 120 driven by the first drive assembly 300.

[0084] In one embodiment, the rotating shaft 610 includes a first output shaft, a second output shaft, and a third output shaft arranged sequentially. The end of the first output shaft away from the second output shaft is connected to one of the eccentric wheels 620, and the end of the third output shaft away from the first output shaft is connected to another eccentric wheel 620. Both ends of the second output shaft are connected to the first output shaft and the third output shaft via couplings.

[0085] Referring to Figure 1, the rotating shaft 610 is divided into multiple segments and connected by couplings, which makes the force on the rotating shaft 610 more uniform at different positions, improving the overall stability and reliability of the rotating shaft 610. The couplings can be rigid couplings or flexible couplings. The bearing housing 310 connects to the second output shaft, driving the first output shaft, the third output shaft and the two connecting seats 500 to translate. The coupling not only ensures the rotational synchronization of the two eccentric wheels 620, but also reduces the overall weight of the entire structure and reduces energy consumption.

[0086] In an embodiment of this utility model, the conveying mechanism further includes a base 700. Two bases 700 are provided and arranged opposite to each other. Each connecting seat 500 is slidably disposed on one of the bases 700. Each base 700 is provided with a guide shaft 710 along the length direction of the load-bearing rope 120. The connecting seat 500 is slidably connected to the guide shaft 710.

[0087] Please refer to Figures 1 and 2. The two bases 700 are arranged opposite each other. A guide shaft 710 extending horizontally along the moving direction is provided on the base 700. The connecting seat 500 is slidably connected to the guide shaft 710. That is, when the first drive assembly 300 drives the connecting seat 500 to move, the connecting seat 500 moves along the guide shaft 710, making the moving process more stable and avoiding the load-bearing rope 120 from shifting or shaking due to lateral force, which would affect the handling of materials.

[0088] It should be noted that the two ends of the guide shaft 710 are restricted by the base 700. Due to the limited length of the guide shaft 710, the sliding distance of the connecting seat 500, the load-bearing rope 120, and the frame along the guide shaft 710 is limited. In one embodiment, the distance between adjacent heating elements on the mounting plate 400 is set to be consistent with the translational distance of the connecting seat 500, that is, consistent with the length of the guide shaft 710. In this embodiment, the two ends of the guide shaft 710 are defined as the first end and the second end, respectively. When long-distance transportation is required, the first drive assembly 300 drives the connecting seat 500 and the load-bearing rope 120 to move along the length of the load-bearing rope 120 through the rotating shaft 600. That is, the connecting seat 500 moves from the first end to the second end on the guide shaft 710. The second drive assembly 600 drives the rotating shaft 610 and causes the support seat 110 to descend, so that the load-bearing rope 120... The frame, supported by a load, rests on the heating element on the mounting plate 400 to heat the solder paste on the frame. At this time, the load-bearing rope 120 falls into the through slot. The first drive assembly 300 drives the connecting seat 500 and the load-bearing rope 120 to move in opposite directions, that is, the connecting seat 500 moves from the second end to the first end. At this time, the load-bearing rope 120 moves in the through slot and does not contact the frame, so it will not affect the heating of the frame on the mounting plate. When the connecting seat 500 reaches the first end, the second drive assembly 600 drives the rotating shaft 610 and drives the support seat 110 to rise. The load-bearing rope 120 rises and drives the frame to rise away from the heating element. Then, the first drive assembly 300 drives the connecting seat 500 to move towards the second end until it reaches the top of the next heating element. Then it descends to contact the heating element and heats it. The above actions are repeated until all heating elements along the entire length of the load-bearing rope 120 are heated.

[0089] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
