Description

Technical Field

[0001] This disclosure relates to the field of tray unlocking technology, and more specifically, to a tray unlocking mechanism. Background Technology

[0002] Before new energy batteries come off the production line, technicians need to use a pin mechanism to ensure the reliability of the position of multiple rows of battery modules on the tray (i.e., the battery modules need to be pressurized). During the unloading process, workers need to pull out the pins on the tray, which results in a high labor intensity for the technicians. Utility Model Content

[0003] To overcome the problem of high labor intensity for workers caused by manually pulling out the latches of existing trays, this utility model provides a tray unlocking mechanism.

[0004] To achieve the above objectives, this disclosure provides a tray unlocking mechanism, comprising:

[0005] frame;

[0006] Linear modules and slide rails are arranged opposite each other at both ends of the frame and both extend along the direction of the conveyor belt of the transport pallet;

[0007] Two brackets, one of which is slidably connected to the slide rail, and the other is connected to the linear module;

[0008] Two lifting cylinders are respectively mounted on the two brackets;

[0009] The plug-in mechanism has two ends respectively installed at the output ends of the two cylinders. The plug-in mechanism has multiple U-shaped grooves for connecting with the insertion rod of the tray pin mechanism.

[0010] Two clamping cylinders are respectively mounted on the bracket to abut the two ends of the plug-in.

[0011] Optionally, a plurality of rollers are installed on the opposite two walls of the U-shaped groove, the rollers being used to make rolling contact with the insertion rod.

[0012] Optionally, an abutment plate is mounted on the output shaft of the clamping cylinder, and a bolt is mounted on the end of the abutment plate away from the clamping cylinder. The bolt and the abutment plate are used to abut against the insertion / removal mechanism.

[0013] Optionally, a guide rail is mounted on the bracket, and the abutment plate is slidably connected to the guide rail.

[0014] Optionally, the number of U-shaped grooves is two.

[0015] The technical solutions provided by the embodiments of this disclosure may include the following beneficial effects:

[0016] The conveyor belt moves the tray to the tray unlocking mechanism. The linear module drive bracket moves towards the pin mechanism near the tray, so that the wall of the U-shaped groove for the plug-in is located on the outer periphery of the plug-in rod of the plug-in mechanism. The output end of the lifting cylinder extends, allowing the plug-in to move upward, which in turn pushes the circular plate on the plug-in rod upward. After the plug-in rod leaves the socket, the horizontal pushing mechanism of the tray pushes the plug-in rod away from the socket. At this point, the tray pin mechanism can release the restriction on the battery module. While the lifting cylinder is working, the output shafts of the two clamping cylinders extend to abut against the two ends of the plug-in, preventing the plug-in lifting mechanism from raising the tray too high. The tray unlocking mechanism reduces the labor intensity of the workers. Attached Figure Description

[0023] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0024] In this disclosure, unless otherwise stated, directional terms such as "upper," "lower," "front," "rear," "left," and "right" are used for ease of description based on the drawing orientations of the corresponding figures, while "inner" and "outer" are defined based on the contours of the corresponding components themselves. Terms such as "first" and "second" used in this disclosure are used to distinguish one element from another and do not have sequential or importance implications. Furthermore, when the following description refers to the figures, unless otherwise indicated, the same numbers in different figures represent the same or similar elements.

[0025] Please see Figure 1 and Figure 2 This disclosure provides a tray 100 unlocking mechanism. The tray 100 is loaded with multiple rows of battery modules, each row corresponding to a pin 110 of a latching mechanism. The tray 100 unlocking mechanism includes a frame 1, a linear module 21, a slide rail 22, a plug-in 5, two supports 3, two lifting cylinders 41, and two clamping cylinders 6. The linear module 21 and the slide rail 22 are arranged opposite each other at both ends of the frame 1, and both extend along the direction of the conveyor belt (not shown in the figure) of the transport tray 100. The linear module 21 is prior art and will not be described in detail here. One of the two supports 3 is slidably connected to the slide rail 22, and the other is connected to the linear module 21. In other embodiments, two linear modules 21 can be used, each connected to one of the two supports 3. The lifting cylinders 41 are respectively mounted on the two supports 3. The two ends of the plug-in 5 are respectively mounted on the output ends of the two cylinders. The plug-in 5 has multiple U-shaped grooves 51 for plugging into the pin 110 of the tray 100 latching mechanism. Two clamping cylinders 6 are respectively mounted on the bracket 3 to abut the two ends of the plug 5.

[0026] Understandably, the conveyor belt moves the tray 100 to the tray 100 unlocking mechanism. The linear module 21 drives the bracket 3 to move towards the pin mechanism of the tray 100, so that the groove wall of the U-shaped groove 51 of the plug-in 5 is located on the outer periphery of the plug rod 110 of the plug-in 5 mechanism. The output end of the lifting cylinder 41 extends, allowing the plug-in 5 to move upward, thereby pushing the circular plate on the plug rod 110 upward. After the plug rod 110 leaves the socket, the horizontal pushing mechanism of the tray 100 will push the plug rod 110 to move away from the socket. At this point, the pin mechanism of the tray 100 can release the restriction on the battery module. While the lifting cylinder 41 is working, the output shafts of the two clamping cylinders 6 extend to abut against the two ends of the plug-in, preventing the tray 100 from being lifted too high by the plug-in 5. The installation of the tray 100 unlocking mechanism reduces the labor intensity of the workers.

[0027] In one implementation, please refer to Figure 1 and Figure 3Multiple rollers 52 are installed on the opposite walls of the U-shaped groove 51. The rollers 52 are used to roll in contact with the insertion rod 110. When the insertion rod 110 leaves the insertion hole, the horizontal pushing mechanism of the tray 100 will push the insertion rod 110 to move away from the insertion hole. At this time, the insertion rod 110 will roll in contact with the rollers 52. The rollers 52 can reduce the friction between the two and facilitate the movement of the insertion rod 110.

[0028] In one implementation, please refer to Figure 2 and Figure 4 An abutment plate 61 is mounted on the output shaft of the clamping cylinder 6. Two bolts 62 are mounted on the end of the abutment plate 61 furthest from the clamping cylinder 6. The abutment plate 61 and the two bolts 62 are used to abut against the insert 5. When the machining error of the thickness of the abutment plate 61 is large, the abutment plate 61 cannot make complete contact with the end of the insert 5, resulting in poor abutment effect of the abutment plate 61 against the insert 5. In this case, installing the bolts 62 on the end of the abutment plate 61 can increase the contact area between the abutment plate 61 and the insert 5 in the thickness direction, ensuring that the abutment plate 61 can stably abut against the insert 5.

[0029] In one implementation, please refer to Figure 4 A guide rail 63 is installed on the bracket 3, and the abutment plate 61 is slidably connected to the guide rail 63 via a slider.

[0030] In one implementation, please refer to Figure 2 and Figure 3 The number of U-shaped slots 51 is two. Because there are two rows of battery modules on the tray 100 in this application, and the two rows of battery modules correspond to two plugs 110, two U-shaped slots 51 are provided on the plug 5. Of course, in other embodiments, the number of U-shaped slots 51 can be three, four, or five or more, etc.
