Description
Technical Field
[0001] This utility model belongs to the technical field of grippers for cap removal machines, specifically relating to a novel adaptive gripper mechanism for SMT cap removal machines. Background Technology
[0002] The cap removal machine gripper mechanism is a specialized device on the SMT (Surface Mount Technology) production line that automates the removal of temporary mounting caps from electronic components. These caps are used to assist the nozzle in picking up components during the component placement process, but they need to be removed afterward to avoid affecting product assembly and performance.
[0003] Problems with existing technology: The existing cap removal machine's gripper mechanism has different sizes of component caps or shielding caps during use. The size of the part that needs to be removed is usually between 5mm and 80mm. The usual practice is to change different grippers for different shielding cap sizes to ensure the stability and accuracy of gripping. However, this method wastes time changing grippers and reduces production efficiency. Utility Model Content
[0004] The purpose of this invention is to provide a novel adaptive gripper mechanism for SMT cap removal machines. This mechanism can solve the problem that existing cap removal machine gripper mechanisms have different sizes of component caps or shielding caps, and the size of the part that needs to be removed is usually between 5mm and 80mm. The usual practice is to change different grippers for different shielding cap sizes to ensure the stability and accuracy of clamping. However, this method wastes time changing grippers and reduces production efficiency.
[0005] The specific technical solution adopted by this utility model is as follows: A novel adaptive gripper mechanism for an SMT cap remover includes a mounting plate. A connecting bracket is fixedly connected to the front end of the mounting plate. An electric telescopic rod body is fixedly mounted on the upper side of the connecting bracket. The lower end of the electric telescopic rod body is fixedly connected to a drive adjustment component. The left and right sides of the drive adjustment component are slidably connected to two limiting rods, respectively. The upper and lower ends of the two limiting rods are fixedly connected to the upper and lower sides inside the connecting bracket, respectively. Two mounting sensing components are provided at the front end of the drive adjustment component. The two mounting sensing components are respectively inserted into two mounting blocks, each with an internal insertion hole. A gripper body is fixedly connected to the relatively close ends of the two mounting blocks.
[0006] The drive adjustment assembly includes a housing, the upper end of which is fixedly connected to the lower end of the electric telescopic rod body, and limiting sliders are fixedly connected to both the left and right rear sides of the housing.
[0007] The two limiting sliders are slidably connected to the two limiting rods respectively. A drive motor is fixedly installed at the rear end of the housing. The output shaft of the drive motor passes through the rear end of the housing and is fixedly connected to the second bevel gear.
[0008] The second bevel gear meshes with the first bevel gear, the first bevel gear is fixedly connected to the bidirectional screw, and the left and right ends of the bidirectional screw are respectively movably connected to the left and right ends of the housing.
[0009] The bidirectional screw is threadedly connected to two mounting sensor components. The left and right sides inside the housing are fixedly connected to the left and right ends of two guide rods, respectively. Both guide rods are slidably connected to the two mounting sensor components.
[0010] Both of the aforementioned mounting sensing components include mounting brackets, and both mounting brackets are threadedly connected to a bidirectional screw through threaded holes formed inside them.
[0011] Both mounting brackets are slidably connected to two guide rods through two guide holes inside them, and an L-shaped connecting bracket is fixedly connected to the front end of both mounting brackets.
[0012] Both L-shaped connecting brackets are slidably connected to four T-shaped guide rods through two guide holes opened inside their relatively far ends, and the relatively near ends of the four T-shaped guide rods are fixedly connected to two mounting sleeves.
[0013] Both mounting sleeves are connected to two mounting blocks, each with an internal insertion hole, via T-shaped pins. Each of the two T-shaped pins is fitted with a spring.
[0014] Each of the four T-shaped guide rods is fitted with a spring, and each of the two L-shaped connecting frames has a pressure detection sensor body on its relatively close side.
[0015] The technical effects achieved by this utility model are as follows: This invention utilizes a drive motor, bevel gear one, bevel gear two, a bidirectional screw, and a guide rod to drive two mounting sensing components closer together. Then, with the assistance of a mounting block, two gripper bodies move closer together, achieving a clamping and fixing effect on component caps. During the clamping and fixing process, the pressure detection sensor on the mounting sensing components automatically detects the pressure during cap clamping. When the detected pressure reaches a set value, the drive motor automatically shuts off. This allows the device to automatically adapt to the clamping and fixing effect on different caps, ensuring stability and accuracy when clamping caps of different sizes. Frequent replacement of the gripper bodies is unnecessary. The mounting sleeve, T-shaped pin, and mounting block allow for easy disassembly and replacement of damaged gripper bodies.

[0018] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.
[0019] like Figure 1-7 As shown, a novel adaptive gripper mechanism for an SMT cap remover includes a mounting plate 1. A connecting bracket 3 is fixedly connected to the front end of the mounting plate 1. An electric telescopic rod body 4 is fixedly mounted on the upper side of the connecting bracket 3. The lower end of the electric telescopic rod body 4 is fixedly connected to a drive adjustment assembly 8. The left and right sides of the drive adjustment assembly 8 are slidably connected to two limiting rods 2, respectively. The upper and lower ends of the two limiting rods 2 are fixedly connected to the upper and lower sides inside the connecting bracket 3, respectively. Two mounting sensing components 5 are provided at the front end of the drive adjustment assembly 8. The two mounting sensing components 5 are respectively inserted into two mounting blocks 6, each with an internal insertion hole. Each of the relatively close ends of block 6 is fixedly connected to a gripper body 7. The drive adjustment component 8 can drive the two mounting sensing components 5 to move closer to each other. Then, with the cooperation of the two mounting blocks 6, the two gripper bodies 7 can be driven closer to each other, thereby achieving the gripping effect of the component cap. During the gripping process, the gripping pressure can be detected to adapt to caps of different sizes, thus achieving an adaptive gripping effect. With the cooperation of the mounting sensing components 5 and the mounting blocks 6, the gripper bodies 7 can be easily removed from the device after a certain period of use for easy maintenance.
[0020] Furthermore, the drive adjustment assembly includes a housing 81, the upper end of which is fixedly connected to the lower end of the electric telescopic rod body 4. Limiting sliders 86 are fixedly connected to both the left and right sides of the rear end of the housing 81, and the two limiting sliders 86 are slidably connected to the two limiting rods 2 respectively. A drive motor 87 is fixedly installed at the rear end of the housing 81. The output shaft of the drive motor 87 passes through the rear end of the housing 81 and is fixedly connected to a second bevel gear 85. The second bevel gear 85 meshes with a first bevel gear 84, and the first bevel gear 84 is fixedly connected to a bidirectional screw 83. The left and right ends of the bidirectional screw 83 are movably connected to the left and right ends of the housing 81 respectively. The bidirectional screw 83 is threadedly connected to two mounting induction components 5. The left and right sides of the housing 81 are fixedly connected to the left and right ends of the two guide rods 82 respectively. The two guide rods 82 are slidably connected to the two mounting sensor components 5. The stability of the housing 81 during movement can be increased by the cooperation of the limiting slider 86 and the limiting rod 2. The rotation of the output shaft of the drive motor 87 drives the second bevel gear 85 to rotate, and then the first bevel gear 84 can drive the bidirectional screw 83 to rotate. The rotation of the bidirectional screw 83 can adjust the distance between the two mounting sensor components 5, and then the distance between the two gripper bodies 7 can be adjusted by the cooperation of the mounting block 6.
[0021] Furthermore, both mounting induction components 5 include mounting brackets 58. Both mounting brackets 58 are threadedly connected to bidirectional screws 83 through internal threaded holes. Both mounting brackets 58 are slidably connected to two guide rods 82 through two internal guide holes. An L-shaped connecting bracket 51 is fixedly connected to the front end of each mounting bracket 58. Each L-shaped connecting bracket 51 is slidably connected to four T-shaped guide rods 52 through two guide holes at its relatively far ends. The relatively near ends of the four T-shaped guide rods 52 are fixedly connected to two mounting housings 54. Each mounting housing 54 is inserted into two mounting blocks 6, each with an internal insertion hole, through T-shaped pins 55. A second spring 57 is fitted onto each of the two T-shaped pins 55, and a first spring 53 is fitted onto each of the four T-shaped guide rods 52. The relatively near sides of the two L-shaped connecting brackets 51 are each provided with... The pressure sensor body 56, through the rotation of the bidirectional screw 83 and the action of the guide rod 82, can drive the two mounting brackets 58 to move closer together, thereby driving the two L-shaped connecting brackets 51 to move closer together. During the process of driving the two L-shaped connecting brackets 51 to move closer together, the T-shaped guide rod 52, spring 53, mounting sleeve 54 and mounting block 6 can work together to drive the two gripper bodies 7 to move closer together, thereby achieving the effect of clamping and fixing the component cap. During the clamping and fixing process, the two pressure sensor bodies 56 can detect the pressure during the clamping process. When the pressure during the clamping process reaches the set value, the drive motor 87 can be turned off, thereby achieving the effect of automatically adapting to component caps of different sizes.
[0022] The working principle of this utility model is as follows: When clamping and removing the cap from the component, the drive motor 87 is started to drive the bevel gear 85 to rotate, which in turn drives the bidirectional screw 83 to rotate under the action of the bevel gear 84. The rotation of the bidirectional screw 83, with the cooperation of the guide rod 82, drives the two mounting brackets 58 to move closer together. Then, with the cooperation of the L-shaped connecting bracket 51, T-shaped guide rod 52, spring 53, mounting sleeve 54 and mounting block 6, the two gripper bodies 7 can be moved closer together. During the process of moving the two gripper bodies 7 closer together, the two pressure detection sensors 56 can detect the pressure of the two gripper bodies 7 during the clamping process of the component cap. When the pressure reaches the set value, it means that the component cap is stably clamped and fixed. At this time, the drive motor 87 is automatically turned off. Then, the electric telescopic rod body 4 is started to drive the drive adjustment component 8 to move upward. With the cooperation of the mounting sensing component 5, mounting block 6 and gripper body 7, the cap can be moved upward, thereby realizing the process of removing the cap from the component.
[0023] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
