Description

Technical Field

[0001] The utility model relates to the technical field of feeding devices, in particular to a stacked material lifting module. Background Art

[0002] Capacitors are provided in electronic products such as electronic watches. There are several capacitors on one carrier board, and then several carrier boards are stacked together for convenient transportation. Then the carrier boards are cut and the capacitors are taken off. After the capacitors are produced, they need to go through a quality inspection process to detect whether the performance of each capacitor on each carrier board meets the standard. Since the carrier boards are stacked together, they need to be taken out one by one from the stack during inspection. When unloading, the carrier boards also need to be stacked together for subsequent transportation.

[0003] Since the stacked carrier boards are prone to tilting to one side or collapsing after reaching a certain height, the automatic material taking mechanism will not be able to accurately grasp the carrier boards during material taking, affecting the feeding. If the manual feeding method is used, the efficiency is relatively low and cannot meet the requirements of automated production. Therefore, it is necessary to design a lifting mechanism to cooperate with automated equipment for automatic loading and unloading. Summary of the Utility Model

Specific embodiments

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0025] As Figure 1 - Figure 2 shown, a preferred embodiment of the present utility model proposes a stacked material lifting module, which is mainly composed of a lifting plate 2, a bottom plate 1, a double-output rod screw motor 5, a retaining bar 3 and a stop mechanism 4. The lifting plate 2 is located above the bottom plate 1 and is connected to the bottom plate 1 through a guiding rod 6. The guiding rod 6 is vertically fixed at the bottom of the lifting plate 2 and is inserted through the bottom plate 1 up and down to play a guiding role. The double-output rod screw motor 5 is used to control the up and down movement of the lifting plate 2. There are four retaining bars 3, with every two as a group, distributed oppositely. Fixed blocks 16 are installed at the bottoms of the four retaining bars 3. The fixed blocks 16 are slidably connected to the slide rails fixed on the bottom plate 1 through sliders. A limiting space is formed between the four retaining bars 3 for accommodating the stacked circuit boards. The stop mechanism 4 is used to prevent the retaining bars 3 from sliding.

[0026] Four guiding rods 6 are provided, which are respectively vertically fixed at the four corners of the bottom of the lifting plate 2. The guiding rods 6 are inserted through the bottom plate 1 up and down through linear bushings. The lower ends of the four guiding rods are connected through a connecting plate 11 to improve the stability of the up and down sliding of the guiding rod 6.

[0027] As shown Figure 2 in FIG. 1, a motor fixing base 8 is installed at the middle part of the bottom of the bottom plate 1, and the double-output shaft screw motor 5 is fixedly installed on the motor fixing base 8. There is an avoidance hole in the middle of the bottom plate 1. Since the screw rods of the double-output shaft screw motor 5 extend from both ends of the motor, the motor can control the rotation of the screw rods, thereby controlling the up and down movement of the screw rods. The upper end of the screw rod passes through the avoidance hole and is rotatably connected to the bottom of the lifting plate 2. When the screw rod rotates, it can drive the lifting plate 2 to move up and down.

[0028] A sheet metal 12 is arranged below the bottom plate 1. An upper limit switch 13 and a lower limit switch 14 are respectively arranged on the upper and lower sides of the sheet metal 12. At the same time, a light blocking plate 15 is installed at the lower end of the screw rod. Both the upper limit switch 13 and the lower limit switch 14 are located on the moving path of the light blocking plate 15. When the screw rod rotates, it will move up and down, thereby driving the light blocking plate 15 to move up and down. The light blocking plate 15 cooperates with the upper limit switch 13 and the lower limit switch 14 to control the lifting height of the lifting plate 2.

[0029] Four limit columns 7 are vertically fixed to the bottom of the lifting plate 2. When the lifting plate 2 descends to a specified height, the lower ends of the limit columns 7 will abut against the bottom plate 1, playing a role in limiting, and at the same time, it can also support the lifting plate 2.

[0030] As shown Figure 1 in FIG. 2, the four slide rails on the bottom plate 1 are distributed in a "cross" shape, and the four stop bars 3 are arranged vertically and slide along the slide rails. According to the different sizes of the carrier plates, the four stop bars 3 can slide along the slide rails to adjust the size of the limiting space, so as to limit the stacked carrier plates and prevent them from skewing.

[0031] There are also four through holes distributed in a "cross" shape on the lifting plate 2, corresponding to the four stop bars 3 respectively. The upper ends of the stop bars 3 pass through the through holes, and the lifting plate 2 is used to carry the stacked carrier plates.

[0032] Refer to Figure 2 FIG. 3. Four synchronous pulleys 9 are arranged below the bottom plate 1, corresponding to the four stop bars 3 respectively. The synchronous pulleys 9 are rotatably connected to the fixing plate 19 fixedly installed at the bottom of the bottom plate 1 and are distributed oppositely. Two synchronous pulleys 9 distributed oppositely are connected by a synchronous belt 10, and two stop bars 3 distributed oppositely are fixedly connected to the side of the synchronous belt 10 opposite to the moving direction through a connecting piece 17. When the synchronous pulley 9 rotates, it will drive the synchronous belt 10 to move, and the synchronous belt 10 will drive the two stop bars 3 to move towards or away from each other, thereby adjusting the size of the limiting space.

[0033] In this embodiment, it is manually adjusted. In other technical solutions, a motor can also be added to drive one of the synchronous pulleys 9 to rotate, thereby driving the synchronous belt 10 to move and realizing automatic adjustment.

[0034] like Figure 3 , Figure 4 As shown, in the two groups of symmetrically distributed baffles 3, a stop mechanism 4 is provided on one of the baffles 3. When the positions of the four baffles 3 are adjusted, the stop mechanism 4 can lock the baffle 3 to prevent it from moving.

[0035] The stop mechanism 4 is composed of a guide block 41, a pressure rod 42, a pressure sheet 43, a connecting rod 45 and a locking bolt 46, wherein the guide block 41 is fixed to the side of the stop bar 3, and a guide hole is provided on the guide block 41, and the pressure rod 42 is slidably connected with the guide hole. A strip hole is provided on the connecting rod 45, and the lower end of the pressure rod 42 is rotatably connected with the strip hole through a pin shaft, and the locking bolt 46 is inserted and connected with the fixing block 16 up and down, and the upper end of the locking bolt 46 is hinged with the lower end of the connecting rod 45.

[0036] The pressing plate 43 is fixed to the upper end of the pressing rod 42, and the return spring 44 is sleeved on the pressing rod 42, and the two ends of the return spring 44 are respectively in contact with the pressing plate 43 and the guide block 41. When the pressing rod 42 is pressed down, the return spring 44 will be compressed, the pressing rod 42 will press the connecting rod 45 down, the pin shaft will move relative to the strip hole, and at the same time the connecting rod 45 will press the locking bolt 46 down.

[0037] A limit plate 20 is also provided on the bottom plate 1. The limit plate 20 has a limit hole. The limit hole is strip-shaped and extends along the sliding direction of the blocking bar 3. The lower end of the locking bolt 46 passes through the limit hole and is threadedly connected to the nut 21. The locking bolt 46 and the limit hole are clearance-matched. When the connecting rod 45 presses the locking bolt 46 downward, the nut 21 at the lower end of the locking bolt 46 will not contact the limit plate 20, so that the blocking bar 3 can slide relative to the slide rail.

[0038] On the contrary, when the pressure rod 42 is not subjected to external force, under the action of the return spring 44, the pressure rod 42 will move up and pull up the connecting rod 45, and the connecting rod 45 will pull up the locking bolt 46. At this time, the nut 21 at the lower end of the locking bolt 46 will be tightly pressed against the limit plate 20. At this time, the baffle bar 3 cannot slide freely and plays a stopping role.

[0039] In other technical solutions, the lower end of the locking bolt 46 may also be designed to be thicker to ensure that the locking bolt 46 does not separate from the limiting hole on the limiting plate 20 when it is lifted.

[0040] After the positions of the four baffles 3 are adjusted and locked, the double-outlet screw motor 5 will drive the lifting plate 2 to move up and down. When loading, each time a plurality of stacked carrier plates placed on the lifting plate 2 are taken away, the lifting plate 2 will be lifted up to a certain height, and reciprocate.

[0041] When blanking, every time a carrier board is placed on the lifting plate 2, the lifting plate 2 can descend a certain height, thus completing the stacking of the carrier boards.

[0042] Sensors 18 are also provided at the tops of two of the retaining bars 3 for detecting whether the topmost carrier board has reached the specified height, so as to facilitate the subsequent material taking mechanism to take materials.

[0043] The above technical solutions only reflect the preferred technical solutions of the technical solutions of the present utility model. Some changes that those skilled in the art of this technology may make to some parts thereof all reflect the principles of the present utility model and fall within the protection scope of the present utility model.
