Description

Technical Field

[0001] This application relates to the field of battery cover processing equipment, and in particular to an installation nesting anti-pressurization device. Background Technology

[0002] The battery cover is fitted into a nest within the hole on the flange face to connect with the lower housing. The battery cover is often installed using a punch press, but the time interval between triggering and completing the punch press operation is extremely short, making it impossible to provide protection during the process. Therefore, a pre-installed safety feature is needed, meaning the device cannot start when the safety mechanism is triggered, thereby improving safety performance. Summary of the Invention

[0003] In view of this, this application provides an installation of a nested anti-crushing hand device, which can improve safety performance.

[0004] To achieve the above objectives, this application employs the following technical solution:

[0005] A device for installing a nested anti-pinch hand is characterized by comprising a worktable, an insertion mechanism fixedly installed on the worktable for inserting a nest into a hole in the battery cover, and a pressing device fixedly installed on the worktable for pressing the nest into the hole in the battery cover. The pressing device includes a support frame fixedly installed on the worktable and a pressing cylinder installed on the support frame and located above the insertion mechanism. An observation hole for viewing the insertion mechanism is provided in the middle of the front side of the support frame. Optical gratings are fixedly installed on both the left and right sides of the support frame. The optical gratings are used to detect whether there is any obstruction in the areas on the left and right sides of the support frame. The optical gratings are connected to a control unit, which is also connected to a solenoid valve. The solenoid valve is connected to the air path of the pressing cylinder. The control unit controls the solenoid valve to cut off the air path and stop the pressing cylinder from working based on the obstruction signal fed back by the optical gratings.

[0006] The aforementioned application describes a nested anti-hand-pressing device that, by installing two light gratings on a support frame, can simultaneously detect whether a hand has reached into the area on both sides of the support frame. If so, the device will cut off the air circuit via a solenoid valve to stop the downward-pressing cylinder from working, thereby improving safety performance.

[0007] In some embodiments, the pressing cylinder includes a main cylinder and a pressing head fixedly mounted on the piston rod of the main cylinder.

[0008] In some embodiments, a connecting plate is fixedly mounted on the piston rod of the main cylinder, and a vertically extending guide rod is fixedly mounted on the connecting plate. A guide sleeve is fixedly mounted on the support frame, and the guide rod moves telescopically within the guide sleeve. A sensing plate is fixedly mounted on the upper end of the guide rod. A sensing bracket is fixedly mounted on the support frame, and a position sensor is mounted on the sensing bracket. A first elongated slot extending vertically is provided on the sensing bracket, and the position sensor is fixedly mounted in the first elongated slot by bolts. An adjusting rod is also threadedly connected to the sensing bracket, and the lower end of the adjusting rod rests against the position sensor to finely adjust the height position of the position sensor.

[0009] The guide rod and guide sleeve guide the cylinder, while the sensor plate and position sensor determine the cylinder position. During installation, the position sensor can be partially tightened by first tightening the bolts, and then the position sensor can be adjusted by using the adjusting rod to finely adjust its height. Finally, it is tightened with bolts.

[0010] In some embodiments, the insertion mechanism includes a body fixedly mounted on a workbench, a movable rod vertically connected to a cavity within the body, and a spring pressing against the movable rod and the cavity. The bottom of the movable rod is provided with a limiting part to prevent it from detaching from the body. The upper end of the body has a support platform supporting the bottom of the outer edge of the battery cover. The upper end of the movable rod is provided with a step for placing the nest.

[0011] The movable rod is inserted into the hole in the battery cover for positioning. The nest is manually placed into the step of the movable rod. When the pressure cylinder descends, the movable rod descends and pushes the nest into the hole. When the pressure cylinder resets, the spring drives the movable rod to reset upwards and is locked by the limiting part.

[0012] In some embodiments, the outer wall of the movable rod is provided with one or more vertically penetrating slots, and the main body is provided with chip removal holes that connect to the cavity, the chip removal holes being inclined. Since a large amount of material debris is generated during operation, this debris can be discharged through the slots and chip removal holes, preventing blockage of the movable rod.

[0013] In some embodiments, the left grating is arranged in the front-to-back direction, and the right grating extends in the left-to-right direction. A placement tray for storing nested items and a manual switch for starting the pressing cylinder are also provided on the worktable on the right side of the support frame.

[0014] As can be seen from the above technical solution, this application has at least the following advantages and positive effects:

[0015] This application discloses a nested anti-hand-pressing device. By installing two light gratings on the support frame, it can simultaneously detect whether a hand has reached into the area on both sides of the support frame. If so, the air circuit is cut off by a solenoid valve to stop the working of the pressing cylinder, thereby improving safety performance. Attached Figure Description

[0022] To make the objectives, technical solutions, and advantages of this application clearer, the application will be described in further detail below with reference to the accompanying drawings. The terminology used in the embodiments section of this application is only for explaining specific embodiments and is not intended to limit the application.

[0023] See Figures 1 to 5This application provides an installation nesting anti-pinch device, characterized by: a workbench 1, an insertion mechanism 2 fixedly installed on the workbench 1 for inserting the nest 6 into the hole 41 of the battery cover 4, and a pressing device 3 fixedly installed on the workbench 1 for pressing the nest 6 into the hole 41 of the battery cover 4; the pressing device 3 includes a support frame 31 fixedly installed on the workbench 1 and a pressing cylinder 32 installed on the support frame 31 and located above the insertion mechanism 2; the support frame 31 has an observation hole 311 in the middle of its front side, through which the insertion mechanism 2 can be seen; gratings 5 ​​are fixedly installed on both the left and right sides of the support frame 31, the gratings 5 ​​are used to detect whether there is any obstruction in the area on the left and right sides of the support frame 31; the gratings 5 ​​are connected to a control unit, the control unit is also connected to a solenoid valve, the solenoid valve is connected to the air circuit of the pressing cylinder 32; the control unit controls the solenoid valve to cut off the air circuit and stop the pressing cylinder 32 from working according to the obstruction signal fed back by the gratings 5.

[0024] The installation of the nested anti-hand-pressing device can simultaneously detect whether a hand is inserted into the area on both sides of the support frame 31 by installing two light gratings 5 ​​on the support frame 31. If so, the air circuit is cut off by the solenoid valve to stop the operation of the pressing cylinder 32, thereby improving safety performance.

[0025] The pressing cylinder 32 includes a main cylinder 321 and a pressing head 322 fixedly mounted on the piston rod of the main cylinder 321.

[0026] A connecting plate 33 is fixedly installed on the piston rod of the main cylinder 321. A vertically extending guide rod 34 is fixedly installed on the connecting plate 33. A guide sleeve 35 is fixedly installed on the support frame 31. The guide rod 34 moves telescopically within the guide sleeve 35. A sensing plate 36 is fixedly installed on the upper end of the guide rod 34. A sensing bracket 37 is fixedly installed on the support frame 31. A position sensor 38 is also provided on the sensing bracket 37. A vertically extending first long groove 371 is provided on the sensing bracket 37. The position sensor 38 is fixedly installed in the first long groove 371 by bolts. An adjusting rod 39 is also threadedly connected to the sensing bracket 37. The lower end of the adjusting rod 39 rests on the position sensor 38 to finely adjust the height position of the position sensor 38.

[0027] The guide rod 34 and guide sleeve 35 serve to guide the cylinder, while the sensing plate 36 and position sensor 38 determine the position of the cylinder. During installation, the position sensor 38 can be partially tightened by first tightening the bolts, and the position sensor 38 can be adjusted by adjusting the rod 39 to push it up, thus finely adjusting its height. Finally, it is tightened with bolts.

[0028] The insertion mechanism 2 includes a body 21 fixedly mounted on the workbench 1, a movable rod 22 vertically movably connected to the cavity 211 of the body 21, and a spring 23 pressing against the movable rod 22 and the cavity 211. The bottom of the movable rod 22 is provided with a limiting part 221 to prevent it from falling out of the body 21. The upper end of the body 21 has a support platform that supports the bottom of the outer edge of the battery cover 4. The upper end of the movable rod 22 is provided with a step 222 for placing the nest 6.

[0029] The movable rod 22 is inserted into the hole 41 of the battery cover 4 for positioning. The nest 6 is manually placed into the step 222 of the movable rod 22. When the pressure cylinder 32 descends, the movable rod 22 descends and can push the nest 6 into the hole 41. When the pressure cylinder 32 returns to its original position, the spring 23 drives the movable rod 22 to return to its original position and is locked by the limiting part 221.

[0030] The outer wall of the movable rod 22 is provided with one or more vertically penetrating slots 223, and the body 21 is provided with a chip discharge hole 212 communicating with the cavity 211. The chip discharge hole 212 is inclined. Since a large amount of material chips are generated during operation, these chips can be discharged through the slots 223 and the chip discharge hole 212 to avoid clogging the movable rod 22.

[0031] The left-side grating 5 is arranged along the front-to-back direction, and the right-side grating 5 extends along the left-to-right direction. On the workbench 1 to the right of the support frame 31, there is also a placement tray 7 for storing the nested parts 6 and a manual switch 8 for activating the pressing cylinder 32. The operator uses their left hand to move the battery cover from left to right, aligning the holes with the insertion mechanism 2. The left-side grating 5 is arranged along the front-to-back direction, making it easier for the operator to pull the battery cover without having to extend their arm excessively. The right hand is used to insert the nested parts into the insertion mechanism 2. The right-side grating 5 is arranged along the left-to-right direction, allowing for wider coverage on the right side. The manual switch 8 is also located on the right side, so that only after the right hand is withdrawn is there a spare hand to press the manual switch, improving safety and processing efficiency.

[0032] The following is a brief description of the working process and usage method of installing a nested anti-crushing hand device according to the above embodiment:

[0033] The worker holds the battery box cover in their left hand and aligns the corresponding hole 41 on the battery box cover with the movable rod 22 of the insertion mechanism 2 through the observation hole 311. With their right hand, they place the nest on the placement plate 7 onto the movable rod 22, then withdraw their right hand and press the manual switch to start the pressing cylinder 32, which drives the nest 6 into the hole 41, completing one installation. The above work is repeated for subsequent installations.

[0034] When an employee's left or right hand enters the area covered by the grating 5, it indicates that they are too close to the pressure cylinder 32. At this time, the solenoid valve closes the air circuit, and pressing the manual switch will prevent the pressure cylinder 32 from moving, effectively preventing the pressure cylinder 32 from injuring the employee.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the embodiments of this application, and are not intended to limit them; although the embodiments of this application have been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
