Description

Technical Field

[0001] This utility model relates to the field of lifting device technology, and in particular to a lifting device for a manual assembly table. Background Technology

[0002] In modern industrial production, especially in manufacturing scenarios involving multiple stages and collaborative operations of multiple equipment, manual assembly plays a crucial role. Taking the assembly of electronic products, the assembly of small mechanical parts, and the debugging of precision instruments as examples, these stages often require manual handling of various parts and semi-finished products to ensure that the quality and performance of the products meet standards.

[0003] Existing manual assembly tables are basically simple structures consisting of a tabletop and a support frame. However, currently, there is often a lack of unified height standards in the design of assembly line conveyor platforms, various assembly equipment, and manual assembly tables. This leads to significant height differences between different equipment in actual production. As a result, when goods are transferred from the assembly line to the assembly table, additional manual handling or the use of other auxiliary tools is required, increasing the complexity and labor intensity of the operation. At the same time, during manual assembly, goods are often placed in an orientation that does not meet the assembly requirements. Workers need to move the goods again or use other tools to rotate them to adjust them to the correct orientation. This operation is very cumbersome and increases the risk of damage to the goods. Utility Model Content

[0004] To overcome the problems of traditional assembly tables not being able to adjust their height and requiring a lot of time to adjust when the goods are not placed in the correct orientation, a manual assembly table lifting device is proposed.

[0005] The technical solution is as follows: A manual assembly table lifting device includes an equipment box, with a carrying tray for placing goods at the top of the equipment box. A cylinder group for controlling the height of the carrying tray is installed inside the equipment box. A connecting plate for connecting with other platforms is engaged at the front end of the carrying tray. A circular groove is opened at the top of the carrying tray. A turntable for adjusting the direction of the goods is connected to the bearing inside the groove. A goods positioning mechanism for clamping the goods on the turntable is installed on the rear side of the top of the carrying tray. Anti-fall edges are welded to the rear side and both sides of the top of the carrying tray to prevent the goods from falling.

[0006] Furthermore, the connecting plate has a guide structure that is lower in the front and higher in the back. Rubber positioning blocks are fixedly connected to the upper and lower ends of the connecting plate near the bearing plate. The front end of the bearing plate has a slot, and the upper and lower ends of the slot have positioning holes that match the positions of the rubber positioning blocks. The rubber positioning blocks are fitted and connected to the positioning holes.

[0007] Furthermore, the upper part of the turntable is equipped with rollers to facilitate the movement of goods on the carrier plate. There are three sets of rollers, and the rollers are evenly distributed in a ring around the turntable.

[0008] Furthermore, the product positioning mechanism includes a mounting box, a servo motor, a threaded rod, a threaded sleeve, and a clamping plate. The mounting box is fixed to the upper end of the carrier plate, and the servo motor is installed on the right end of the mounting box.

[0009] Furthermore, a threaded rod is installed on the left end of the servo motor output shaft. The two ends of the threaded rod are respectively provided with reverse threads, and the outer drive is connected with symmetrical threaded sleeves. A clamping plate is welded to the front end of the threaded sleeve, and the clamping plate has an "L" shaped structure.

[0010] Furthermore, casters are installed at the bottom of the equipment box, and all casters are equipped with brakes.

[0011] Furthermore, the rear end and both sides of the equipment box are fixedly connected to limit slides, and the outer side of the bearing plate is welded with limit sliders that match the position of the limit slides. The limit sliders are located inside the limit slides and the two are slidably connected.

[0012] The beneficial effects are as follows: This utility model can precisely control the height of the carrier plate through the cylinder group installed inside the equipment box. The height of the carrier plate can be flexibly adjusted according to actual needs to ensure perfect docking with the assembly line conveyor platform and other assembly equipment. Through the guide structure design of the connecting plate with a lower front and higher rear, the goods can be smoothly transferred from other platforms to the carrier plate or from the carrier plate to other platforms with the help of the guiding action of the connecting plate, which greatly shortens the goods transfer time and improves the continuity and efficiency of the production process. The turntable at the top of the carrier plate is connected to the inner side of the circular groove through the bearing and can be rotated freely. After the goods are placed on the turntable, if it is found that the placement direction of the goods does not meet the assembly requirements, the staff can easily rotate the turntable manually to quickly adjust the goods to the appropriate direction.

[0019] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0020] like Figures 1-5 As shown, this utility model provides an embodiment: a manual assembly table lifting device, including an equipment box 1, a carrying tray 3 for placing goods is provided at the upper end of the equipment box 1, a cylinder group 2 for controlling the height of the carrying tray 3 is installed inside the equipment box 1, a connecting plate 4 for connecting with other platforms is engaged at the front end of the carrying tray 3, a circular groove 5 is provided at the upper end of the carrying tray 3, a turntable 6 for adjusting the direction of the goods carried is connected to the bearing inside the groove 5, a goods positioning mechanism for clamping the goods on the turntable 6 is installed on the rear side of the upper end of the carrying tray 3, anti-drop edges 12 are welded to the rear side and left and right sides of the upper end of the carrying tray 3 to prevent the goods from falling, universal wheels 15 are installed at the lower end of the equipment box 1, all universal wheels 15 are equipped with brakes, a limiting slide 13 is fixedly connected to the rear end and left and right ends of the equipment box 1, a limiting slider 14 matching the position of the limiting slide 13 is welded to the outside of the carrying tray 3, the limiting slider 14 is located inside the limiting slide 13 and the two are slidably connected.

[0021] Please see Figure 3-4 In this embodiment, the connecting plate 4 is a guide structure with a lower front and a higher rear. Rubber positioning blocks 8 are fixedly connected to the upper and lower ends of the connecting plate 4 near the support plate 3. The front end of the support plate 3 has a slot 9. The upper and lower ends of the slot 9 have positioning holes 10 that match the positions of the rubber positioning blocks 8. The rubber positioning blocks 8 are fitted and connected to the positioning holes 10. The connecting plate 4 and the support plate 3 adopt a detachable structure. When it is necessary to remove the connecting plate 4, gently pull the connecting plate 4 outward by hand to make the rubber positioning blocks 8 come out of the positioning holes 10 of the slot 9, and then the connecting plate 4 can be removed from the support plate 3.

[0022] Please see Figure 2 In this embodiment, the upper end of the turntable 6 is equipped with rollers 11 to facilitate the movement of goods on the carrier plate 3. There are three sets of rollers 11, and the rollers 11 are distributed in a ring at equal intervals with the turntable 6 as the center.

[0023] Please see Figure 5In this embodiment, the goods positioning mechanism includes a mounting box 701, a servo motor 702, a threaded rod 703, a threaded sleeve 704, and a clamping plate 705. The mounting box 701 is fixed to the upper end of the bearing plate 3. The servo motor 702 is mounted on the right end of the mounting box 701, and the threaded rod 703 is mounted on the left end of the output shaft of the servo motor 702. The two ends of the threaded rod 703 are respectively provided with reverse threads, and the outer side is connected to a symmetrical threaded sleeve 704. The front end of the threaded sleeve 704 is welded to a clamping plate 705, which has an "L" shape structure. The goods positioning mechanism is mounted on the rear side of the upper end of the bearing plate 3. When operating the goods, the output shaft of the servo motor 702 rotates, driving the threaded rod 703 to rotate. The outer side of the threaded rod 703 is connected to a symmetrical threaded sleeve 704. Since the thread directions at both ends of the threaded rod 703 are opposite, when the threaded rod 703 rotates, the two threaded sleeves 704 will move towards the middle along the threaded rod 703. The threaded sleeve 704 has an "L"-shaped clamping plate 705 welded to its front end. As the threaded sleeve 704 moves, the clamping plate 705 will gradually approach and clamp the goods on the turntable 6, firmly positioning the goods on the carrier plate 3 to prevent the goods from moving during the assembly process.

[0024] When using this lifting device, the bottom of the device is equipped with a universal wheel 15 with a brake. After pushing the device to the designated location, step on the brake of the universal wheel 15 to prevent displacement during the operation.

[0025] According to actual work requirements, the cylinder group 2 installed inside the equipment box 1 is activated. The cylinder group 2 is used to control the height adjustment of the bearing plate 3. During the movement of the bearing plate 3, the limiting slider 14 welded on its outer side will slide along the inner side of the limiting slide frame 13 at the rear end and left and right ends of the equipment box 1 to ensure that the bearing plate 3 remains stable during the lifting process.

[0026] The height is adjusted so that the connecting plate 4 overlaps with other platforms such as assembly line conveyor platforms, so that goods can be smoothly transferred from other platforms to the carrying plate 3, or from the carrying plate 3 to other platforms;

[0027] With the help of the connecting plate 4 and the rollers 11, the goods are transferred to the turntable 6 on the upper end of the carrying plate 3. The upper end of the carrying plate 3 has a circular groove 5. The turntable 6 is connected to the inside of the groove 5 by a bearing, which can be rotated freely. If the placement of the goods does not meet the assembly requirements, the turntable 6 can be manually rotated to adjust the goods to the appropriate direction to meet the assembly requirements.

[0028] A product positioning mechanism is installed on the rear side of the upper end of the bearing plate 3. When operating the product, the output shaft of the servo motor 702 rotates, driving the threaded rod 703 to rotate. Symmetrical threaded sleeves 704 are connected to the outer side of the threaded rod 703. Because the threads at both ends of the threaded rod 703 are in opposite directions, when the threaded rod 703 rotates, the two threaded sleeves 704 move towards the center along the threaded rod 703. An "L"-shaped clamping plate 705 is welded to the front end of the threaded sleeve 704. As the threaded sleeve 704 moves, the clamping plate 705 gradually approaches and clamps the product on the turntable 6, firmly positioning the product on the bearing plate 3 and preventing the product from moving during assembly.

[0029] The connecting plate 4 and the carrier plate 3 adopt a detachable structure. When it is necessary to remove the connecting plate 4, gently pull the connecting plate 4 outward by hand so that the rubber positioning block 8 can be dislodged from the positioning hole 10 of the slot 9, and the connecting plate 4 can be removed from the carrier plate 3.
