The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0021] In the description of this utility model, unless otherwise explicitly defined, the terms "setting", "installing", "connecting", "linking", etc. should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in combination with the specific content of the technical solution.

[0022] The following is as follows Figures 1 to 8 This invention describes a transmission device according to an embodiment of the present invention.

[0023] like Figure 1 and Figure 8 As shown, a transmission device according to an embodiment of the present utility model includes... The system comprises a base frame 100, a lead screw lifting module 200, a first moving component 300, a second moving component 400, and a first guide positioning component 500. Several placement cavities 110 are arranged longitudinally side-by-side within the base frame 100, each with a feed inlet. The lead screw lifting module 200 is located within the base frame 100, positioned in front of the feed inlet of each placement cavity 110. A support seat 210 is provided at the movable end of the lead screw lifting module 200. The first moving component 300 is mounted on the support seat 210 and is adapted to receive workpieces from the outside. The second moving component 400 is mounted on the support seat 210 and is adapted to receive workpieces conveyed by the first moving component 300 and convey them to a workstation within the placement cavity 110. The first guide positioning component 500 is mounted on the support seat 210 and located on both sides of the first moving component 300. The first guide positioning component 500 is adapted to adjust the position of the workpiece on the second moving component 400.

[0024] During operation, the first moving component 300 first receives the external workpiece and transfers it to the movable end of the second moving component 400. The movable end of the first guiding and positioning component 500 is located on one side of the first moving component 300, and the fixed end of the first guiding and positioning component 500 is located on the other side. When the workpiece enters the first moving component 300, the movable end of the first guiding and positioning component 500 pushes the workpiece towards the fixed end of the first guiding and positioning component 500, so that one side of the workpiece is in contact with the fixed end of the first guiding and positioning component 500, thereby ensuring accurate horizontal positioning of the workpiece. Next, the movable end of the first guiding and positioning component 500 moves in the opposite direction, away from the fixed end of the first guiding and positioning component 500, to avoid interfering with subsequent workpiece transfer operations. Then, the workpiece is moved to the feed inlet of the placement cavity 110 by the lead screw lifting module 200, and finally, the movable end of the second moving component 400 sends the workpiece into the working position inside the placement cavity 110. After the workpiece stably arrives at the working position...

[0025] It is understandable that the lead screw lifting module 200 can be located on the left front side, right front side or directly front side of the feed inlet of the placement cavity 110.

[0026] It is understandable that the lead screw lifting module 200 and the first guide positioning component 500 can operate synchronously.

[0027] Understandably, the lead screw lifting module 200 uses a motor-driven lead screw to move the second moving component 400 carrying the workpiece to the feed inlet of the placement cavity 110 with high precision. This design effectively solves the problem of insufficient positioning accuracy in existing belt drive structures due to belt wear, slack, and aging caused by elongation, thus meeting the high-precision requirements for lifting and positioning during the loading and unloading of the test fixture.

[0028] Understandably, the fact that the screw lifting module 200 is located inside the base frame 100 and in front of the placement cavity 110 allows for access to and maintenance of the screw lifting module 200 without disassembling the entire machine, simplifying maintenance procedures and reducing downtime.

[0029] Understandably, the support frame 210 may also have a vision sensor (not shown in the figure) to determine whether the workpiece has completely reached the second moving component 400. Alternatively, the displacement stroke of the first moving component 300 can be controlled by performing stroke calculations in advance to ensure that the workpiece is completely on the second moving component 400.

[0030] In some specific embodiments of this utility model, the first moving component 300 includes a first belt drive mechanism 310, a second belt drive mechanism 320, and a third belt drive mechanism 330 arranged side by side from left to right. The first belt drive mechanism 310, the second belt drive mechanism 320, and the third belt drive mechanism 330 are connected by a drive rod 340. One end of the second belt drive mechanism 320 is connected to a drive motor 350, and the other end of the second belt drive mechanism 320 is fixedly connected to the drive rod 340. The first belt drive mechanism 310, the second belt drive mechanism 320, the third belt drive mechanism 330, and the drive motor 350 are mounted on the support frame 210.

[0031] like Figure 3 As shown, in this embodiment, the rotating movable end of the drive motor 350 is connected to one end of the second belt drive mechanism 320, and the other end of the second belt drive mechanism 320 is fixedly connected to the transmission rod 340, so that the drive motor 350 can drive the transmission rod 340 to rotate through the second belt drive mechanism 320. The transmission rod 340 further drives the first belt drive mechanism 310 and the third belt drive mechanism 330 to perform transmission, so that the first belt drive mechanism 310 and the third belt drive mechanism 330 can carry the workpiece stably for transmission and transport the workpiece to the top of the second moving component 400.

[0032] Understandably, during the transmission process, the bottom of the workpiece first partially contacts the first belt drive mechanism 310 and the third belt drive mechanism 330, and then, driven by the friction of the belts, the entire bottom of the workpiece completely contacts the first belt drive mechanism 310 and the third belt drive mechanism 330, and finally moves above the second moving component 400.

[0033] It is understood that the second belt drive mechanism 320 includes a first drive pulley 321, a second drive pulley 322, and a first transmission belt 323 tensioned between them. The first drive pulley 321 is fixedly connected to the movable end of the drive motor 350, and the second drive pulley 322 is fixedly connected to the transmission rod 340. Thus, the torque of the drive motor 350 can be transmitted to the transmission rod 340 through the second belt drive mechanism 320. It is understood that the first belt drive mechanism 310 includes a rotating component 311, a third rotating wheel 312, a fourth transmission wheel 313, and a second transmission belt 314 tensioned between them. One end of the rotating component 311 is rotatably connected to the third rotating wheel 312 via a first bearing 315, and the other end of the rotating component 311 is connected to the support seat 210. One end of the transmission rod 340 is fixedly connected to the fourth transmission wheel 313 and extends to be rotatably connected to the support seat 210 via a second bearing (not shown in the figure). When the transmission rod 340 rotates, it drives the fourth transmission wheel 313 to rotate, which in turn drives the second transmission belt 314 and the third rotating wheel 312 to rotate, causing the second transmission belt 314 to operate in order to realize the conveying of the workpiece.

[0034] It is understandable that the third belt drive mechanism 330 has the same structure as the first belt drive mechanism 310, and the two are arranged symmetrically on the left and right.

[0035] In some specific embodiments of this utility model, the support frame 210 includes a cover plate 211 and a base 212 connected vertically. The cover plate 211 and the base 212 form a cavity. The cover plate 211 has a first through groove 2111 and a second through groove 2112, which communicate with the cavity. A first belt drive mechanism 310, a third belt drive mechanism 330, a second moving component 400, and a first guide positioning component 500 are disposed on the upper end surface of the cover plate 211. A drive motor 350 is disposed on the lower end surface of the cover plate 211. A second belt drive mechanism 320 passes through the first through groove 2111 and is connected to the drive motor 350 and the transmission rod 340 respectively. The base 212 is connected to the movable end of the lead screw lifting module 200.

[0036] like Figure 3 As shown in this embodiment, the cavity formed by the cover plate 211 and the base 212 can accommodate the drive motor, making the overall equipment structure more compact and effectively saving space. In addition, the air passage pipes (not shown in the figure) and circuit control lines (not shown in the figure) of other structures can be introduced into the cavity through the third through slot 2112 for orderly arrangement, which makes the overall structure layout clear and orderly, and facilitates subsequent maintenance and installation.

[0037] It is understandable that multiple second passages 2112 can be provided, and they can be arranged at the corresponding positions on the cover plate 211 according to the actual routing paths of the gas pipeline and the electrical control line.

[0038] It is understandable that, such as Figure 3As shown, the cover plate 211 may also be provided with a first fixing plate 2113 and a second fixing plate 2114. The rotating part 311 is set on the first fixing plate 2113. One end of the transmission rod 340 is rotatably connected to the first fixing plate 2113 through a second bearing. The third belt drive mechanism 330 is set on the second fixing plate 2114.

[0039] In some specific embodiments of this utility model, the second moving component 400 includes a rodless cylinder 410, a protrusion 420, and a drive shaft 430. The rodless cylinder 410 is mounted on the support frame 210. The slider of the rodless cylinder 410 is connected to a conveyor frame 440. A first driving cylinder 450 and a clamping block 460 are fixed on the conveyor frame 440. The output shaft of the first driving cylinder 450 is drivenly connected to a transverse plate 470. Both ends of the transverse plate 470 are connected to longitudinal plates 480. The two longitudinal plates 480 are symmetrically provided with inclined grooves 481. The clamping block 460 is located between the two longitudinal plates 480. The clamping block 460 has a first through hole 461 in the vertical direction and a second through hole 462 in the horizontal direction. The protrusion 420 is located in the first through hole 461. The drive shaft 430 passes through the protrusion 420, and both ends of the drive shaft 430 are respectively engaged with the two inclined grooves 481 and the two second through holes 462.

[0040] like Figure 1 , Figure 4 and Figure 5 As shown, in this embodiment, when the first belt drive mechanism 310 and the third belt drive mechanism 330 transport the workpiece above the second moving assembly 400, the first drive cylinder 450 drives the transverse plate 470 to move backward, causing the two longitudinal plates 480 to move backward synchronously. Since both ends of the drive shaft 430 are confined within the inclined groove 481, the backward movement of the longitudinal plates 480 causes the inclined groove 481 to move relative to the drive shaft 430, and the slope of the inclined groove 481 forces the drive shaft 430 to produce a vertical displacement. The drive shaft 430, through the protrusion 420 fixed thereto, drives the protrusion 420 to slide upward within the first through hole 461 of the clamping block 460 until the upper end of the protrusion 420 engages with the limiting hole at the bottom of the workpiece, thereby completing the positioning of the workpiece and ensuring that the workpiece will not shift relative to the conveyor frame 440. After the protrusion 420 fixes the workpiece and is located at the feed inlet of the placement cavity 110, the rodless cylinder 410 drives the conveyor frame 440 to move into the placement cavity 110, sending the positioned workpiece into the placement cavity 110.

[0041] After the workpiece is placed in the placement cavity 110, the first drive cylinder 450 drives the transverse plate 470 to move forward, thereby driving the longitudinal plate 480 to move forward, so that the transmission shaft 430 moves along a certain slope in the inclined groove 481 and drives the protrusion 420 to descend, releasing the engagement with the limiting hole at the bottom of the workpiece. Then, the lead screw lifting module 200 drives the conveyor frame 440 to descend, so that the conveyor frame 440 is completely separated from the workpiece. The rodless cylinder 410 drives the conveyor frame 440 to leave the placement cavity 110.

[0042] Understandably, the conveyor frame 440 may also be equipped with a fixed block 441 and a transmission guide rail 442. The transmission guide rail 442 is connected to the movable end of the rodless cylinder 410, the lower end of the fixed block 441 is connected to the bearing seat 210, and the upper end of the fixed block 441 is movably connected to the transmission guide rail 442, thereby improving the overall stability of the conveyor frame 440 and enabling better placement of workpieces.

[0043] In some specific embodiments of this utility model, the first guide positioning component 500 includes a first guide member 510 and a second guide plate 520 disposed on the left and right sides of the first moving component 300. The second guide plate 520 is disposed on the drive support frame 210. A guide cylinder 530 is disposed on one side of the first guide member 510. The guide cylinder 530 is disposed at the fixed end of the first moving component 300. The movable end of the guide cylinder 530 is adapted to drive the first guide member 510 to move in the left and right direction.

[0044] like Figure 6 As shown, in this embodiment, the first guide member 510 includes a horizontal plate 511 and a vertical plate 512 connected vertically. The vertical plate 512 is disposed on the left side of the third belt drive mechanism 320. The guide cylinder 530 is disposed on the first fixed plate 2113. The movable end of the guide cylinder 530 passes through the first fixed plate 2113 and is connected to the vertical plate 512. The movable end of the guide cylinder 530 can drive the horizontal plate 511 and the vertical plate 512 to move towards the second guide plate 520. The horizontal plate 511 can contact one side of the workpiece during the movement, thereby pushing the other side of the workpiece to fit against the second guide plate 520, thus ensuring that the workpiece is in the correct position facing the placement cavity 110 in the horizontal direction. It can be understood that multiple guide cylinders 530 can be provided, such as two, three, or four.

[0045] In some specific embodiments of this utility model, a limiting cylinder 600 is also included. The limiting cylinder 600 is disposed on the support frame 210 and is located on the front side of the second moving component 400. The movable end of the limiting cylinder 600 is adapted to drive in the up and down direction.

[0046] like Figure 2 and Figure 7As shown, in this embodiment, when the movable end of the limiting cylinder 600 rises to the extended position, it can block the workpiece. This prevents the first belt drive mechanism 310 and the third belt drive mechanism 330 from excessively moving the workpiece, thereby ensuring that the workpiece can accurately cooperate with subsequent processes. When the conveyor frame 440 transports the workpiece into the workstation in the placement cavity 110, the movable end of the limiting cylinder 600 descends to avoid affecting the transport of the workpiece.

[0047] In some specific embodiments of this utility model, a positioning detection component 700 is also included. The positioning detection component 700 includes a second driving cylinder 710, which is disposed inside the first moving component 300. The movable end of the second driving cylinder 710 is provided with a positioning protrusion 720.

[0048] like Figure 7 As shown, in this embodiment, when the workpiece is conveyed to a predetermined position by the first belt drive mechanism 310 and the third belt drive mechanism 330, the movable end of the second drive cylinder 710 drives the positioning protrusion 720 to move towards the workpiece. If the workpiece is accurately positioned, the positioning protrusion 720 will smoothly engage with the corresponding positioning hole slot on the workpiece; this successful physical engagement itself indicates that the workpiece has been accurately positioned. It is understood that two positioning protrusions 720 are preferably provided to work together to ensure the balance and stability of the workpiece positioning. It is also understood that the movable end of the second drive cylinder 710 may be equipped with several electronic probes (not shown in the figure) to further ensure the accuracy of the workpiece position.

[0049] In some specific embodiments of this utility model, a second guide positioning component 800 is also included. The second guide positioning component 800 includes a plurality of guide wheels 810, which are located on the left and right sides of the placement cavity 110.

[0050] like Figure 1 and Figure 2 As shown, in this embodiment, the second guide positioning component 800 is provided with two sets. One set of the second guide positioning components 800 located at the lower position is located on the lower side of the workstation and is adapted to contact the bottom surface of the workpiece to provide support and transmission. The other set of the second guide positioning components 800 located at the higher position is located on the left and right sides of the workstation and is adapted to contact the sides of the workpiece. It can effectively guide and center the workpiece when it is placed, ensuring that the workpiece enters the placement cavity 110 smoothly and accurately.

[0051] In some specific embodiments of this utility model, the base frame 100 also includes a housing 120, which has a window 121 facing the feed inlet of the placement cavity 110.

[0052] like Figure 8As shown, in this embodiment, the housing 120 is made of sheet metal to form a closed protective structure, which can effectively block the transmission of mechanical noise during operation, thereby improving the working environment and enhancing operational comfort.

[0053] Understandably, the front of the housing 120 can be configured as a door structure, and the remaining parts can be designed as individually detachable modules. This design facilitates maintenance of the internal lead screw lifting module 200, first moving component 300, second moving component 400, first guide positioning component 500, limit cylinder 600, and positioning detection component 700. The window 121 facilitates the passage and placement of workpieces onto the first moving component 300, and also allows for observation of the device's operating status, thus avoiding the safety risks associated with opening the housing for observation while the equipment is running.

[0054] Understandably, the window 121 is positioned directly opposite the feed inlet of one of the placement chambers 110. This layout allows the workpiece to be directly fed in after the initial positioning, reducing the need for repeated positioning adjustments by the lead screw lifting module 200 and improving the efficiency of a single operation.

[0055] This utility model embodiment also discloses a testing device, including the aforementioned transmission device.

[0056] When the equipment is in use, the screw lifting module 200 drives the first connecting piece 240, the connecting plate 250 and the bearing seat 210 to move to the window 121 to receive the workpiece. The workpiece is suitable to enter the first belt drive mechanism 310 and the third belt drive mechanism 330 set on the bearing seat 210 through the external transmission mechanism. The drive motor 350 enables the first belt drive mechanism 310 and the third belt drive mechanism 330 to rotate through the second belt drive mechanism 320 and the transmission rod 340. The first belt drive mechanism 310 and the third belt drive mechanism 330 transmit the workpiece to the conveyor frame 440. The guide cylinder 530 simultaneously pushes the workpiece to the second guide plate 520 located on the other side of the workpiece through the first guide piece 510 located on one side of the workpiece, so that the workpiece can be correctly oriented towards the feed port of the placement cavity 110.

[0057] Furthermore, the movable end of the limiting cylinder 600 rises to prevent the workpiece from moving excessively on the first belt drive mechanism 310 and the third belt drive mechanism 330. When the first belt drive mechanism 310 and the third belt drive mechanism 330 stop moving, the second drive cylinder 710 drives the positioning protrusion 720 to rise, detecting whether the workpiece is in position. After detection, the second drive cylinder 710 drives the positioning protrusion 720 to descend and reset. Then, the movable end of the first drive cylinder 450 pushes the transmission shaft 430 upward in the inclined groove 481, thereby pushing the protrusion 420 upward within the first through hole 461, achieving the limiting and positioning of the workpiece. While the workpiece is positioned by the second moving component 400, the first drive motor 230 can drive the carrier 210 to move to the feed port of the placement cavity 110. When the workpiece is at the feed port of the placement cavity 110, the rodless cylinder 410 drives the workpiece into the workstation in the placement cavity 110 through the conveyor frame 440 and the protrusion 420. Several guide wheels 710 of the second guide positioning component 700 can assist in the positioning and guidance of the workpiece when it enters the workstation.

[0058] Once the workpiece has fully entered the workstation, the first drive cylinder 450 drives the transverse plate 470 to move forward, thereby driving the longitudinal plate 480 to move forward. This causes the transmission shaft 430 to move along a certain slope in the inclined groove 481 and drive the protrusion 420 to descend, releasing the engagement with the limiting hole at the bottom of the workpiece. Then, the lead screw lifting module 200 drives the conveyor frame 440 to descend, so that the conveyor frame 440 is completely separated from the workpiece. The rodless cylinder 410 drives the conveyor frame 440 to leave the placement cavity 110 and return to its original position, waiting for the next round of workpiece transportation.

[0059] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
