Description

Technical Field

[0001] This invention relates to the field of production equipment technology, and in particular to a material transfer device. Background Technology

[0002] With the development of new technologies, factories have made great progress in intelligent manufacturing. The automation and intelligence of production lines are constantly improving, especially in jobs involving material assembly, where automated production lines are widely used.

[0003] On an automated production line, after materials are fed into the line through the inlet, they flow through different workstations via the conveyor mechanism, undergo processing at each workstation, and finally exit from the outlet. During this material transfer process, due to the different processes at each workstation, the position of the materials needs to be adjusted. For example, the materials may be in the same position at the first and second workstations, but in a different position at the third and fourth workstations.

[0004] To accommodate the needs of different workstations, production lines are typically divided into multiple sections. Multiple workstations on each section use the same carrier to carry materials. After processing, the processed materials are transferred to another section for further processing by manual transfer. This seriously affects the production efficiency of the production line and also increases the labor intensity of workers. Summary of the Invention

[0005] The main objective of this invention is to provide a material handling device that addresses the technical problem of material switching between different carriers affecting production efficiency in existing automated production lines.

[0019] A slide rail assembly is disposed on the upper frame and extends to the lower frame. The first conveying mechanism and the second conveying mechanism are respectively slidably connected to the slide rail assembly to slide between the upper frame and the lower frame.

[0020] The telescopic component includes a fixed end and a telescopic end. The fixed end is located on the lower frame, and the telescopic end is located at the end of the fixed end near the upper frame and extends and retracts in the vertical direction. The telescopic end is respectively connected to the first conveying mechanism and the second conveying mechanism to drive them to slide along the slide rail assembly.

[0021] Optionally, the slide rail assembly includes a plurality of parallel slide rails, and the first conveying mechanism and the second conveying mechanism are slidably connected to at least two slide rails in the slide rail assembly.

[0022] Optionally, the lifting mechanism further includes a damping element disposed at both ends of the slide rail; wherein, when the first conveying mechanism and the second conveying mechanism slide to the end of the slide rail, the damping element abuts against the first conveying mechanism and the second conveying mechanism to buffer them.

[0023] Optionally, multiple damping elements are provided at both ends of the slide rail.

[0024] Optionally, the material transfer equipment includes a positioning component, which includes a fixed end and a telescopic end; the telescopic end is connected to one side of the fixed end and can extend and retract in a direction away from the fixed end.

[0025] On the material transfer equipment, the positioning component is disposed on the upper end face of the first conveying mechanism and the second conveying mechanism. The telescopic end extends and retracts in the vertical direction to extend and abut against the two opposite end faces of the first fixture and the second fixture for positioning, or retracts to release the first fixture and the second fixture.

[0026] Optionally, the positioning component further includes a positioning block, which is disposed on the telescopic end away from the fixed end, and a guide slope is provided between the end face of the positioning block facing the first fixture and the second fixture and the top surface.

[0027] Optionally, the material transfer equipment includes a third conveying mechanism, which is located below the second conveying mechanism and the third conveying mechanism, and is used to connect the upstream and downstream of the material transfer equipment.

[0028] Optionally, the third conveying mechanism comprises:

[0029] The lifting assembly includes a fixed end and a telescopic end. The fixed end is connected to the lower frame, and the telescopic end is located on the end face of the fixed end near the upper frame and extends and retracts in the vertical direction.

Similarly, the second conveying mechanism is positioned as a second input position on the lower frame, receiving a second fixture from downstream equipment. When positioned on the upper frame as a second output position, it can return the second fixture downstream. The material transfer equipment also includes a shifting mechanism movably connected to the upper support and movable between the first input and second output positions. This shifting mechanism features a material handling structure for picking up and discharging materials, as well as a position adjustment structure for adjusting the material's position. In practical applications, this material transfer equipment can connect two work sections. The first fixture is a carrier suitable for the upstream work section, and the second fixture is a carrier suitable for the downstream work section. After processing, the material from the upstream work section is received by the first fixture and flows into the material transfer equipment. At this time, the first conveying mechanism receives the first fixture at the first input position, and the second conveying mechanism receives the empty second fixture from the downstream work section and adjusts it to the second output position. Then, the material in the first fixture is picked up by the shifting mechanism, and after position adjustment such as pitch change and rotation, it is placed into the second fixture for further processing in the downstream work section. In this technical solution, through the cooperation of the first conveying mechanism, the second conveying mechanism, and the shifting mechanism, the material can be quickly switched between the first and second fixtures, improving the connection speed between the upstream and downstream work sections, thereby improving production efficiency.

[0042] The realization of the objective, functional features and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0043] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0044] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0045] In this invention, unless otherwise explicitly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly. For example, "fixed" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0046] Furthermore, if the embodiments of this invention involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the meaning of "and / or" throughout the text includes three parallel solutions; for example, "A and / or B" includes solution A, solution B, or a solution where both A and B are satisfied simultaneously. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.

[0047] With the continuous development of electronic equipment, the application of automated equipment is becoming increasingly widespread, and the processing of workpieces is gradually shifting from manual to automated methods.

[0048] However, due to the different positional requirements of materials at each workstation during processing, the material's position needs to be adjusted before processing at each workstation. Frequent positional adjustments inevitably lead to a decrease in production efficiency. Existing solutions typically divide the production line into several sections, with each workstation having roughly the same material processing positional requirements. A standardized carrier can be used for material transfer, followed by manual transfer between sections. However, this method significantly increases the labor intensity for workers, and the manual transfer of materials between sections also greatly impacts production efficiency.

[0049] To solve the above-mentioned technical problems, the present invention proposes a material transfer device, which includes: a frame 100, including an upper frame and a lower frame;

[0050] The first conveying mechanism 200 is movably mounted on the frame 100. The first conveying mechanism 200 has a first input position located on the upper frame and a first output position located on the lower frame. The first conveying mechanism 200 receives a first fixture carrying material from upstream of the material transfer equipment at the first input position.

[0051] The second conveying mechanism 300 is movably mounted on the frame 100. The second conveying mechanism 300 has a second input position located on the lower frame and a second output position located on the upper frame. The second conveying mechanism 300 receives an empty second fixture downstream of the material transfer equipment at the second input position.

[0052] A lifting mechanism 400 is mounted on the frame 100. The lifting mechanism 400 is connected to the first conveying mechanism 200 and the second conveying mechanism 300 respectively to drive the first conveying mechanism 200 and the second conveying mechanism 300 to switch positions; and

[0053] The shifting mechanism 500 is movably connected to the upper frame and is used to adjust the position of the material on the first fixture and transfer it to the second fixture;

[0054] The shifting mechanism 500 picks up the material at the first input position, adjusts the position of the material and transfers it to the second output position. The second conveying mechanism 300 adjusts the second fixture to the second output position to receive the material and returns it downstream. The first conveying mechanism 200 adjusts the fixture at the first input position to the first output position and returns it upstream.

[0055] Compared with the prior art, in the technical solution of the present invention, the material transfer equipment includes a frame 100, which has an upper frame and a lower frame. A first conveying mechanism 200 and a second conveying mechanism 300 are movably mounted on the frame 100. The frame 100 is also provided with a lifting mechanism 400, which is connected to the first conveying mechanism 200 and the second conveying mechanism 300 in a transmission manner, driving the first conveying mechanism 200 and the second conveying mechanism 300 to switch between the lower frame and the upper frame. The first conveying mechanism 200 is positioned at a first input position on the upper frame. In the first input position, the first conveying mechanism 200 connects with the upstream equipment of the material transfer equipment to receive the first fixture from the upstream. The first conveying mechanism 200 is positioned at a first output position on the lower frame. In the first output position, the first conveying mechanism 200 can return the first fixture to the upstream of the material transfer equipment. Correspondingly, the second conveying mechanism 300 is positioned at a second input position on the lower frame. The second conveying mechanism 300 can receive the second fixture input from the downstream equipment of the material transfer equipment at the second input position. When the second conveying mechanism 300 is positioned at a second output position on the upper frame, the second conveying mechanism 300 can return the second fixture downstream at this position. In addition, the material transfer equipment is also equipped with a shifting mechanism 500, which is movably connected to the upper support and can move between the first input position and the second output position. The shifting mechanism 500 is equipped with a material picking structure for picking up and discharging materials. Furthermore, the shifting mechanism 500 is also equipped with a position adjustment structure for adjusting the position of the materials. In practical applications, the material transfer equipment can be connected between two work sections. The first fixture is a carrier suitable for the upstream work section, and the second fixture is a carrier suitable for the downstream work section. After the materials are processed in the upstream work section, they are received by the first fixture and flow into the material transfer equipment. At this time, the first conveying mechanism 200 receives the first fixture at the first input position, and the second conveying mechanism 300 receives the empty second fixture from the downstream work section and adjusts it to the second output position. Then, the shifting mechanism 500 picks up the materials in the first fixture, adjusts their position by pitch and rotation, and puts them into the second fixture for further processing in the downstream work section. In this technical solution, the cooperation of the first conveying mechanism 200, the second conveying mechanism 300 and the shifting mechanism 500 can quickly realize the switching of materials between the first fixture and the second fixture, improve the connection speed of materials between the upstream section and the downstream section, and thus improve production efficiency.

[0056] Specifically, such as Figures 1 to 7In this embodiment, the material transfer equipment can be used in the production line of electronic components such as PCB and FPC. The upstream and downstream of the material transfer equipment can be connected through the equipment. The material transfer equipment includes a frame 100, which includes an upper frame and a lower frame. The upper frame and the lower frame can correspond to the upper conveyor belt and the lower conveyor belt of the upstream and downstream workstations. The material transfer equipment also includes a first conveying mechanism 200 and a second conveying mechanism 300, which are movably connected to the frame 100. The first conveying mechanism 200 can be connected to the frame 100 via a sliding connection such as a slide rail, and slides between the upper and lower frames. In this embodiment, the first conveying mechanism 200 can be a conveyor belt structure matching the upstream station of the material transfer equipment. When the first conveying mechanism 200 moves to the upper frame, it connects with the upstream upper conveyor belt, and the first fixture carrying material can be conveyed to the first conveying mechanism 200 via the upper conveyor belt. This position is the first input position. When the first conveying mechanism 200 moves to the lower frame, it connects with the upstream lower conveyor belt, and the first fixture can be... The first conveying mechanism 200 returns to the upstream process from this position, which is the first output position. That is, by switching the position of the first conveying mechanism 200 between the upper and lower frames, the first fixture can be circulated in the upstream process. Similar to the first conveying mechanism 200, the second conveying mechanism 300 is matched with the downstream station of the material transfer equipment. When it moves to the lower frame, it connects with the lower conveyor belt downstream. The lower conveyor belt transports the second fixture to the material transfer equipment and onto the second conveying mechanism 300, which is the second input position. When the second conveying mechanism 300 moves to the upper frame, it connects with the upper conveyor belt downstream, and the received second fixture can be returned from the upper conveyor belt downstream to the downstream process. The second conveying structure can realize the circulation of the second fixture in the downstream process. To enable the switching of the positions of the first conveying mechanism 200 and the second conveying mechanism 300 between the upper and lower frames, a lifting mechanism 400 is also provided on the frame 100. The lifting mechanism 400 can be connected to the two conveying mechanisms. The lifting mechanism 400 can be a standardized device such as a hydraulic cylinder or an electric actuator. Its body can be fixed on the frame 100, and its telescopic rod can extend and retract in the vertical direction. The first conveying mechanism 200 and the second conveying mechanism 300 are connected to the telescopic rod. The extension and retraction of the telescopic rod drives the first conveying mechanism 200 and the second conveying mechanism 300 to move up and down. In order to adapt to the different circulation speeds of the upstream and downstream first fixtures and second fixtures, two lifting mechanisms 400 can be provided, and each can be connected to the first conveying mechanism 200 and the second conveying mechanism 300 individually. The different circulation speeds of the upstream and downstream materials of the material transfer equipment can be met by the individual lifting and lowering of the first conveying mechanism 200 and the second conveying mechanism 300.To facilitate the connection between upstream and downstream materials, the material transfer equipment is also equipped with a shifting mechanism 500. This shifting mechanism 500 can be installed on the upper frame. In addition, to adapt the material positions in the first and second fixtures, the shifting mechanism 500 can be equipped with a position adjustment function. Specifically, when the first fixture flows into the first conveying position, the shifting mechanism 500 can move to the first conveying position and adapt the material position on the first fixture through the position adjustment function. Then, the shifting mechanism 500 takes the material from the first fixture. The empty first fixture is adjusted to the first output position by the first conveying mechanism 200 and flows back upstream for the next cycle. At this time, the empty second fixture downstream can flow into the second input position and be adjusted to the second output position on the upper frame by the second conveying mechanism 300. At this time, the shifting mechanism 500 can adjust the position of the taken material through the position adjustment function, and then put it into the empty second fixture, and flow back downstream with the second fixture to continue the downstream process. In other words, the transfer mechanism 500 enables the transfer of materials between the first fixture and the second fixture. Since the first fixture and the second fixture correspond to different processes in actual production, and the material positions on them also differ, this material transfer equipment facilitates the connection between upstream and downstream processes, eliminating the need for manual material transfer between upstream and downstream, thereby accelerating material processing and improving production efficiency.

[0057] Furthermore, the shifting mechanism 500 includes:

[0058] A crossbeam 510 is provided on the upper frame, and the crossbeam 510 is provided with a slide extending from the first input position to the second output position;

[0059] The telescopic assembly 520 includes a fixed end and a telescopic end. The fixed end is slidably connected to the slide rail, and the telescopic end is located on the side of the fixed end away from the crossbeam 510 and extends and retracts in the vertical direction.

[0060] Material handling bracket 530, located at the telescopic end, has multiple material handling heads slidably connected to it; and

[0061] A pitch-changing assembly 540 is provided on the material pick-up bracket 530. The pitch-changing device is connected to the material pick-up head drive to adjust the distance between the material pick-up heads.

[0062] Specifically, such as Figure 2The shifting mechanism 500 can adjust the spacing of materials to adapt to the different spacing requirements of the first and second fixtures. In this embodiment, the shifting mechanism 500 includes a crossbeam 510 connected to the upper frame. The crossbeam 510 extends from the first input position to the second output position. Support columns can be provided at both ends of the crossbeam 510, which are connected to the frame 100 through the two support columns. The crossbeam 510 is located above the first input position and the second output position. The shifting mechanism 500 is also provided with a slide rail extending along the direction of the crossbeam 510. A telescopic component 520 is slidably connected in the slide rail. On the one hand, it can slide along the slide rail, and on the other hand, it can extend and retract vertically to move closer to or further away from the first input position or the second output position. In addition, in order to facilitate the adjustment of the position of the telescopic component 520 on the slide rail, a driving device can be provided on the crossbeam 510. In this embodiment, the driving device is a motor and a lead screw. The motor housing is fixed on the crossbeam 510, the lead screw extends along the length direction of the crossbeam 510 and is rotatably connected to the crossbeam 510, and the motor shaft of the motor is connected to the lead screw for transmission. The motor can drive the lead screw to rotate. By cooperating with the telescopic component 520, the telescopic component 520 can move on the slide rail. The telescopic component 520 is also equipped with a material picking bracket 530, on which multiple material picking heads are slidably connected. In addition, the material picking bracket 530 is also equipped with a pitch-changing component 540, which is connected to the material picking head drive. The pitch-changing component 540 is driven to adjust the spacing of the material picking heads. In this way, when the shifting mechanism 500 picks up material, the pitch-changing component 540 adjusts the spacing of the material picking heads to adapt to the requirements of the first fixture. After picking up material, the pitch-changing component 540 makes a secondary adjustment to the material picking heads to adapt them to the second fixture. This realizes the switching of material between the first fixture and the second fixture and improves the efficiency of material transfer in the upstream and downstream.

[0063] Furthermore, the lifting mechanism 400 is characterized by comprising:

[0064] The slide rail assembly 410 is located on the upper frame and extends to the lower frame. The first conveying mechanism 200 and the second conveying mechanism 300 are slidably connected to the slide rail assembly 410 so as to slide between the upper frame and the lower frame.

[0065] The telescopic component 420 includes a fixed end and a telescopic end. The fixed end is located on the lower frame, and the telescopic end is located at the end of the fixed end near the upper frame and extends and retracts in the vertical direction. The telescopic end is connected to the first conveying mechanism 200 and the second conveying mechanism 300 respectively to drive them to slide along the slide rail assembly 410.

[0066] Specifically, such as Figure 3To facilitate the switching of the positions of the first conveying mechanism 200 and the second conveying mechanism 300 between the upper and lower frames, in this embodiment, the lifting mechanism 400 includes a slide rail assembly 410 and a telescopic member 420. The slide rail assembly 410 includes a slide rail and a slider that slides along the slide rail. The slide rail is connected to the upper frame and extends vertically. The first conveying mechanism 200 and the second conveying mechanism 300 can be connected to the slider. The sliding of the slider can drive the first conveying mechanism 200 and the second conveying mechanism 300 to slide on the slide rail. To improve the connection strength between the slider and the slide rail, connecting grooves can be formed on both sides of the slide rail. A connecting body is provided on the corresponding slider. By inserting the connecting body into the connecting groove, the slider is prevented from detaching from the slide rail in a direction away from the slide rail, thereby ensuring the stability of the connection. Additionally, the telescopic component 420 can be mounted on the lower frame. The telescopic component 420 can be a telescopic device such as an electric cylinder or pneumatic cylinder. It has a fixed end and a telescopic end. The fixed end can be connected to the lower frame, and the telescopic end can extend and retract vertically. The telescopic end can be connected to the slider, and the extension and retraction of the telescopic end can push the slider to slide, thereby realizing the up-and-down movement of the first conveying mechanism 200 and the second conveying mechanism 300. Furthermore, to achieve independent movement of the first conveying mechanism 200 and the second conveying mechanism 300, two sets of the slide rail assembly 410 and the telescopic component 420 can be separately installed, each set connected to one of the first conveying mechanism 200 or the second conveying mechanism 300, thus realizing the independent movement of the two conveying mechanisms.

[0067] Furthermore, the slide rail assembly 410 includes a plurality of parallel slide rails, and the first conveying mechanism 200 and the second conveying mechanism 300 are respectively slidably connected to at least two slide rails in the slide rail assembly 410.

[0068] Specifically, in order to ensure the stable movement of the first conveying mechanism 200 and the second conveying mechanism 300, the slide rail assembly 410 can be provided with multiple slide rails, which are parallel to each other. In this embodiment, the first conveying mechanism 200 and the second conveying mechanism 300 are slidably connected to two slide rails respectively. By increasing the number of slide rails, on the one hand, the connection strength between the first conveying mechanism 200 and the second conveying mechanism 300 and the slide rail assembly 410 is increased, thereby ensuring the stability of their movement. On the other hand, it is beneficial to reduce the stress on a single slide rail, thereby reducing wear and extending the service life of the slide rail assembly 410.

[0069] Furthermore, the lifting mechanism 400 also includes damping elements 430, which are disposed at both ends of the slide rail; wherein, when the first conveying mechanism 200 and the second conveying mechanism 300 slide to the ends of the slide rail, the damping elements 430 abut against the first conveying mechanism 200 and the second conveying mechanism 300 to buffer them. Multiple damping elements 430 are disposed at both ends of the slide rail.

[0070] Specifically, such as Figure 4 To ensure the stability of the first and second fixtures during position switching, the lifting mechanism 400 is also equipped with damping components 430. These damping components 430 can be linear dampers or shock-absorbing springs, etc. They are located at both ends of the slide rail and extend towards each other. Thus, when the first conveying mechanism 200 and the second conveying mechanism 300 move to the ends of the slide rail, the damping components 430 can abut against the end faces of the first and second conveying mechanisms 200 and 300. By applying damping forces in opposite directions to the first and second conveying mechanisms 200 and 300, they can be slowly decelerated, reducing vibrations caused by sudden stops at the final positions, thereby ensuring the stability of the material on the first and second fixtures. Furthermore, to improve the damping and deceleration effect, multiple damping components 430 can be provided at both ends of the slide rail. The simultaneous action of multiple damping components 430 increases the damping force, thereby enhancing the damping and deceleration effect.

[0071] Furthermore, the material transfer equipment includes a positioning component 700, which includes a fixed end and a telescopic end; the telescopic end is connected to one side of the fixed end and can extend and retract in a direction away from the fixed end.

[0072] In the material transfer equipment, the positioning component 700 is disposed on the upper end face of the first conveying mechanism 200 and the second conveying mechanism 300. The telescopic end extends and retracts in the vertical direction to extend and abut against the two opposite end faces of the first fixture and the second fixture for positioning, or retracts to release the first fixture and the second fixture.

[0073] Specifically, such as Figure 5 and Figure 6To improve the accuracy of material handling by the shifting mechanism 500, the material transfer equipment can be equipped with a positioning component 700. The positioning component 700 has a fixed end and a telescopic end. In this embodiment, the positioning component 700 can be a telescopic cylinder. On the first conveying mechanism 200, the fixed end is fixed to the first conveying mechanism 200, and the telescopic end is disposed on the fixed end and slides in the vertical direction. The telescopic end can extend out of the upper end face of the first conveying mechanism 200 or retract to a position lower than the upper end face. Two positioning components 700 can be arranged at intervals on the first conveying mechanism 200 along the extension direction of the first conveying mechanism 200. The distance between the two can be adapted to the width of the first fixture. When the first fixture flows into the first conveying mechanism 200 from the upstream, the positioning component 700 near the downstream of the first conveying mechanism 200 extends out and abuts against the end face of the first fixture near the downstream. Then, the other positioning component 700 extends out and abuts against the end face of the first fixture near the upstream. The positioning component 700 can limit the first fixture to be located between the two positioning components 700, thereby ensuring the fixed position of the first fixture on the first conveying mechanism 200 and improving the accuracy of the shifting mechanism 500 when picking up materials. Similarly, the same positioning component 700 can be provided on the second conveying mechanism 300. The positioning component 700 abuts against the two opposite end faces of the second fixture in the upstream and downstream directions, thereby fixing the second fixture in position on the second conveying mechanism 300 and improving the stability of the shifting component when feeding material onto the second fixture.

[0074] Furthermore, the positioning component 700 also includes a positioning block, which is located on the telescopic end away from the fixed end, and a guide slope is provided between the end face of the positioning block facing the first fixture and the second fixture and the top surface.

[0075] To further improve positioning accuracy, a positioning block can be provided at the telescopic end of the positioning component 700. The positioning block has a guide slope on the side near the end face of the fixture. That is, the distance between the opposite end faces of the positioning blocks on the two positioning components 700 gradually decreases from top to bottom. In this way, when the telescopic end of the positioning component 700 rises, if the first fixture and the second fixture are angularly deviated in the horizontal direction, the guide slope of the positioning block abuts against the end face of the first fixture or the second fixture to correct its angle, thereby further improving the accuracy of the material picking and placing position.

[0076] Furthermore, the material transfer equipment includes a third conveying mechanism 600, which is located below the second conveying mechanism 300 and the third conveying mechanism 600, and is used to connect the upstream and downstream of the material transfer equipment.

[0077] The third conveying mechanism 600 includes:

[0078] The lifting assembly 610 includes a fixed end and a telescopic end. The fixed end is connected to the lower frame, and the telescopic end is located on the end face of the fixed end near the upper frame and extends and retracts in the vertical direction.

[0079] The belt conveyor assembly 620 is located at the telescopic end and moves up and down with the telescopic end. The belt conveyor assembly 620 extends in the direction upstream and downstream of the material transfer equipment.

[0080] Specifically, such as Figure 1 and Figure 7 To broaden the applicability of this material transfer equipment, a third conveying mechanism 600 can be provided. This third conveying mechanism 600 can be located below the first conveying mechanism 200 and the second conveying mechanism 300. In this embodiment, the third conveying mechanism 600 includes a lifting assembly 610 and a belt conveyor assembly 620. The lifting assembly 610 can be a telescopic device with a fixed end and a telescopic end, such as a cylinder or hydraulic cylinder. The fixed end of the lifting assembly 610 is connected to the lower frame, and its telescopic end extends in the vertical direction. The belt conveyor assembly 620 is connected to the telescopic end, and the belt conveyor assembly 620 extends in the upstream and downstream direction of the material transfer equipment. The telescopic end can drive the belt conveyor assembly 620 to move up and down vertically. In practical applications, the belt conveyor assembly 620 can rise to connect with the lower conveyor belt upstream and downstream of the material transfer equipment or descend to detach from the lower conveyor belt. When the first fixture and the second fixture are two different fixtures, the belt conveyor assembly 620 is located below the lower conveyor belt. In this case, the first conveying mechanism 200, the second conveying mechanism 300, and the shifting mechanism 500 realize the transfer of materials between the first fixture and the second fixture. When the first fixture and the second fixture are the same type of fixture, there is no need to transfer materials between the first fixture and the second fixture. The material transfer device will rise to connect with the lower conveyor belts of the upstream and downstream sides. The first conveyor mechanism 200 and the second conveyor mechanism 300 will connect with the upper conveyor belts of the upstream and downstream sides, respectively, and the first conveyor mechanism 200 and the second conveyor mechanism 300 will connect with each other on the upper level. When the fixture flows into the material transfer device, it can be directly conveyed downstream via the first conveyor mechanism 200 and the second conveyor mechanism 300. When an empty fixture flows into the material transfer device from the lower conveyor belt downstream, it can be directly returned to the upstream via the belt conveyor assembly 620, thereby realizing the circulation of the fixture on the production line. In this technical solution, by setting the third conveyor mechanism 600, the material transfer in both cases of different fixtures and the same fixture can be met, thereby expanding the application range of the material transfer device.
