Description

Technical Field

[0001] This utility model belongs to the technical field of diaphragm assembly equipment, and in particular relates to a diaphragm stacking device. Background Technology

[0002] Placing the diaphragm inside the basket is one of the steps in diaphragm assembly. The current assembly method is to place the basket on the assembly line, and then the worker sits on one side of the assembly line. The diaphragm is placed in front of the worker. During assembly, the worker picks up the basket with one hand and the diaphragm with the other hand, aligns the position of the copper wire on the diaphragm with the position corresponding to the notch on the basket, and presses it with the index finger to complete the stacking of the diaphragm. After stacking, it is put back on the assembly line so that it can be transported to the next station.

[0003] When operating manually, the copper wires on the diaphragm are not easy to align with the notch in the basin holder, requiring secondary adjustments, which is inefficient. Utility Model Content

[0004] To address the shortcomings of the existing technology, this utility model provides a membrane stacking device that can replace manual assembly, improve the degree of automation, and eliminate the need for secondary adjustment of the membrane placement, thus achieving high efficiency.

[0005] In order to achieve the purpose of this utility model, the following solution is proposed:

[0006] A diaphragm stacking device, comprising:

[0007] The basin rack feeding assembly includes a conveyor belt, a receiving groove corresponding to the end of the conveyor belt in the conveying direction, a turntable concentrically arranged in the receiving groove, a suction cup on the top of the turntable, and a retractable positioning pin on one side of the turntable for limiting the notch of the basin rack.

[0008] The diaphragm feeding assembly is located on one side of the conveyor belt and includes a diaphragm storage cylinder. A vertical strip groove is provided on one side of the diaphragm storage cylinder, and a support platform is provided at the bottom of the diaphragm storage cylinder. A lifting column is provided inside the support platform for pushing the diaphragm upward. A crossbeam is provided directly above the center of the receiving groove and the center of the diaphragm storage cylinder. A vertically telescopic gripper is provided along the length of the crossbeam for clamping the pushed-out diaphragm.

[0009] Furthermore, the bottom of the receiving groove is provided with a vertical through hole, and the positioning pin includes a pin body that passes through the through hole. The lower end of the pin body is provided with a limiting plate, and the limiting plate is located at the bottom of the outer wall of the receiving groove. The middle part of the pin body is provided with a limiting ring, and a spring passes through the pin body. One end of the spring abuts against the limiting ring, and the other end abuts against the inner bottom of the receiving groove.

[0010] Furthermore, the top of the pin is equipped with a ball bearing.

[0011] Furthermore, the line connecting the center of the receiving tank and the center of the diaphragm storage cylinder is perpendicular to the length direction of the conveyor belt.

[0012] Furthermore, the arms of the gripper are made of rubber.

[0013] The beneficial effects of this utility model are as follows:

[0014] It can automatically determine the position of the notch on the basin rack and place the diaphragm in the diaphragm storage cylinder. The copper wire extends outward along the strip groove into the diaphragm storage cylinder, so that the lifting column pushes the diaphragm vertically upward. The orientation of the copper wire is consistent with the orientation of the notch, so that when the gripper clamps the diaphragm into the basin rack, it ensures that the copper wire is placed in the notch accordingly. No secondary adjustment is required, which is highly efficient. Attached Figure Description

Detailed Implementation

[0021] To make the objectives, technical solutions and advantages of the present utility model clearer, the implementation methods of the present utility model will be described in detail below with reference to the accompanying drawings. However, the embodiments described in the present utility model are only some embodiments of the present utility model, and not all embodiments.

[0022] like Figures 1-4 As shown, this embodiment provides a membrane stacking device, including a basin rack feeding assembly 10 and a membrane feeding assembly 20.

[0023] Specifically, such as Figures 1-2 As shown, the basin rack loading assembly 10 includes a conveyor belt 11, a turntable 13, and positioning pins 14. The conveyor belt 11 is used to transport the basin rack 1. Two baffles are provided on both sides of the conveyor belt 11, and the distance between the baffles is tangent to the outer wall of the basin rack 1, so that the basin rack 1 remains in the middle of the conveyor belt 11 during transport. A receiving platform is provided at the end of the conveyor belt 11 in the transport direction. A receiving groove 12 is vertically recessed downwards from the top of the receiving platform facing the end of the conveyor belt 11 in the transport direction. The turntable 13 is concentrically located within the receiving groove 12. A rotating shaft is provided at the bottom of the turntable 13, and a drive motor is provided through the bottom of the receiving groove 12 to drive the turntable 13 to rotate. A suction cup 131 is provided at the top of the turntable 13 to adhere to the planar position of the bottom of the basin rack 1, so that the basin rack 1 rotates synchronously with the turntable 13.

[0024] The positioning pin 14 is located in the diameter direction of the receiving groove 12 and is opposite to the conveyor belt 11. The positioning pin 14 is extended and retracted in the vertical direction to limit the notch 3 of the basin frame 1 when the basin frame 1 rotates. When the positioning pin 14 passes through the notch 3, the turntable 13 stops rotating, thereby realizing the positioning of the basin frame 1.

[0025] The diaphragm feeding assembly 20 includes a diaphragm storage cylinder 21, a support platform 22, a lifting column 23, a crossbeam 24, and grippers 25. The diaphragm storage cylinder 21 is vertically positioned on one side of the end of the conveyor belt 11 in the conveying direction, and is used to temporarily store the diaphragms 2. The support platform 22 is located at the lower end of the diaphragm storage cylinder 21. A vertically oriented strip groove 211 is provided on one side of the diaphragm storage cylinder 21 to accommodate the copper wires on the diaphragms 2, and the direction of the strip groove 211 should be on the same side as the direction of the positioning pin 14 in the receiving groove 12. The lifting column 23 is located on the top of the support platform 22 and inside the diaphragm storage cylinder 21, and is used to push the diaphragms 2 one by one vertically upward. The crossbeam 24 is positioned directly above the line connecting the center of the receiving groove 12 and the center of the diaphragm storage cylinder 21. A lifting rod is provided on the lower side of the crossbeam 24 and is movable along the length of the crossbeam 24. Grippers 25 are located at the lower end of the lifting rod and are used to hold the pushed-out diaphragms 25.

[0026] The specific implementation process is as follows:

[0027] One by one, basin racks 1 with their large ends facing upwards are placed on the conveyor belt 11 for transport. When the foremost basin rack 1 enters the receiving groove 12 under the action of the conveyor belt 11, the bottom of the basin rack 1 is held in place by the suction cup 131. At this time, the positioning pin 14 is compressed under the action of the basin rack 1. The drive motor is started to make the turntable 13 rotate slowly. At the same time, the gripper 25 is activated to pick up the uppermost membrane 2 placed in the membrane storage cylinder 21 and move it directly above the receiving groove 12. When the notch 3 on the basin rack 1 corresponds to the upper end of the positioning pin 14, the basin rack 1 loses the compression of the positioning pin 14, so that the positioning pin 14 enters the notch 3. At this time, the drive motor is stopped to stop the rotation of the turntable 13, and the lifting rod is vertically downward to place the membrane 2 on the basin rack 1, thereby realizing the stacking of the membrane 2. During stacking, it is ensured that the copper wires on the membrane 2 are placed in the notch 3. After stacking and assembly, the membrane 2 can be removed by a mechanical gripper or manually and put into the production line for the next process.

[0028] Specifically, such as Figures 3-4 As shown, the bottom of the receiving groove 12 is provided with a through hole 121. The positioning pin 14 includes a pin body 141, a limiting plate 142, a limiting ring 143, and a spring 144. The pin body 141 is vertically inserted into the through hole 121. The limiting plate 142 is located at the lower end of the pin body 141 and is located on the bottom surface of the receiving platform. The limiting ring 143 is located in the middle of the pin body 141 and is located in the receiving groove 12. The spring 144 is inserted into the pin body 141, and the upper end of the spring 144 abuts against the bottom surface of the limiting ring 143, and the lower end of the spring 144 abuts against the inner bottom surface of the receiving groove 12.

[0029] When the suction cup 131 adsorbs the basin holder 1, the upper end of the positioning pin 14 is subjected to the downward pressure of the basin holder 1, which causes the pin body 141 to move vertically downward, thereby compressing the spring 144. When the upper end of the positioning pin 14 corresponds to the notch 3, the downward pressure on the upper end of the positioning pin 14 disappears, the spring 144 returns to its original position, and the upper end of the pin body 141 enters the notch 3 to achieve positioning of the basin holder 1.

[0030] Preferably, to prevent the basin frame 1 from being deformed by the reaction force of the positioning pin 14 when the positioning pin 14 is pressed down, the elastic force of the spring 144 is made less than the deformation force of the basin frame 1.

[0031] Preferably, in order to reduce the friction between the basin frame 1 and the pin 141, a ball bearing is provided on the top of the pin 141 for rotation.

[0032] Preferably, the line connecting the center of the receiving trough 12 and the center of the diaphragm storage cylinder 21 is perpendicular to the length direction of the conveyor belt 11, so as to shorten the travel of the lifting rod.

[0033] Preferably, each arm of the gripper 25 is made of rubber to avoid damaging the outer periphery of the diaphragm 2.

[0034] The above description is merely a preferred embodiment of this utility model and does not imply its uniqueness or limitation. Those skilled in the art should understand that various changes or equivalent substitutions made to this utility model without departing from its scope are all within the protection scope of this utility model.
