Description

Technical Field

[0001] The utility model relates to automatic screw locking equipment. Background Art

[0002] An automatic screw locking machine is an automated device used to lock screws. It can realize automatic screw conveying, tightening, and detection through various electric and pneumatic components. Existing automatic screw locking machines are usually designed as air-blowing structures or adsorption structures. Among them, the air-blowing locking method uses compressed air to blow the screws to the position where the electric screwdriver takes the screws, and then uses the electric screwdriver to automatically lock the screws into the product. This locking method can achieve continuous operation.

[0003] During the assembly process of some products (such as remote controls), the upper shell and the lower shell of the product need to be fixed together. During this process, it is necessary to tighten the screws to assemble the upper shell and the lower shell of the product together. The existing automatic screw locking equipment for locking the upper shell and the lower shell together needs to use some snap-fit ​​structures to fix the upper shell and the lower shell together to prevent the two from shifting relative to each other during the screw locking process and affecting the screw locking operation. Usually, some snap-fit ​​structures are installed along the periphery of the shell on a processing platform where the upper shell and the lower shell are placed. Each time the operation is performed, the operator is required to turn the snap-fit ​​structures one by one to fix the upper shell and the lower shell together, which is very time-consuming and affects the operation efficiency.

[0006] The processing platform is provided with a cavity for accommodating the screw products to be locked.

[0007] The clamping component includes a rotating telescopic cylinder and a clamping plate. The rotating telescopic cylinder drives the clamping plate to rotate and move up and down. The rotating telescopic cylinder is arranged below the processing platform. The driving shaft of the rotating telescopic cylinder passes through the processing platform and is connected to the clamping plate. The clamping plate is located above the processing platform. The clamping plate can press the screw product to be locked into the concave cavity on the processing platform.

[0008] The X-axis driving mechanism is arranged on the gantry, and the screw locking mechanism is slidably arranged on the crossbeam of the gantry. The X-axis driving mechanism drives the screw locking mechanism to move along the X direction.

[0009] The Y-axis drive mechanism drives the processing platform and the clamping components to move along the Y direction.

[0010] The Z-axis drive mechanism drives the screw locking mechanism to move along the Z direction.

[0011] The X-axis driving mechanism, the Y-axis driving mechanism, the Z-axis driving mechanism, the screw locking mechanism, and the rotating and telescopic cylinder are all electrically connected to the controller.

[0012] The automatic screw locking device of the utility model can provide support for the X-axis driving mechanism and the screw locking mechanism. The upper shell and the lower shell of the screw locking product (such as a remote control) are aligned and placed in the concave cavity on the processing platform. Under the driving action of the rotating telescopic cylinder, the pressing plate above the processing platform rotates a certain angle (such as 90 degrees) and then moves downward to press the upper shell laterally, thereby pressing the upper shell and the lower shell in the concave cavity on the processing platform, so that the upper shell and the lower shell of the screw locking product are pressed and fixed together to prevent the two from shifting relative to each other during the screw locking process. Under the coordinated action of the axis drive mechanism, the Y-axis drive mechanism, and the Z-axis drive mechanism, the screw locking mechanism can use screws to lock the upper shell and the lower shell together. After the screw locking is completed, under the driving action of the rotating telescopic cylinder, the clamping plate above the processing platform moves upward and then rotates a certain angle (such as 90 degrees) to reset. The clamping component of the utility model can automatically and quickly complete the clamping positioning and loosening and resetting of the upper shell and the lower shell of the product to be screwed. There is no need for the operator to turn the buckle structure one by one to fix the upper shell and the lower shell together. The structure is simple and the operating efficiency is high.

At this time, the operator can remove the product on the processing platform where the screw locking operation has been completed, and then place the upper shell and the lower shell of the new product to be screwed in the concave cavity on the processing platform. In the process of removing the products where the screw locking operation has been completed and placing the upper shell and the lower shell of the new product to be screwed, the operator does not need to force the screw locking mechanism to stop working, so that the screw locking mechanism can continuously perform screw locking operations on the upper shell and the lower shell, thereby greatly improving work efficiency.

[0044] See also Figure 1 and Figure 6 Four pillars 22 are installed at the bottom of the processing platform 2, and the bottoms of the four pillars 22 are respectively fixed at the four corners of the connecting plate 48. In this way, a space for installing the clamping component 3 can be formed between the processing platform 2 and the connecting plate 48. A cavity 21 is formed on the processing platform 2. The cavity 21 is used to accommodate the shell (upper shell and lower shell) of the screw product to be locked. The style of the cavity 21 is adapted to the model of the shell.

The two ends of the pressing plate 32 can simultaneously press the shells (upper shell and lower shell) of the two products to be screwed into the two concave cavities 21 on the processing platform 2. The rotating telescopic cylinder 31 can drive the pressing plate 32 to rotate and move up and down along the Z direction through the driving shaft 311. When the automatic screw locking device of the utility model is not working, the pressing plate 32 moves along the Y direction. The upper shell and the lower shell of the shell of the product to be screwed are aligned and placed in the concave cavity 21 on the processing platform 2 under the driving action of the rotating telescopic cylinder 31. The clamping plate 32 above the processing platform 2 rotates a certain angle (such as 90 degrees) and then moves downward to press laterally on the shell, thereby pressing the shell in the concave cavity 21 on the processing platform 2, so that the upper shell and the lower shell of the shell of the product to be screwed are fixed together to prevent the two from shifting relative to each other during the screw locking process. Under the action of the X-axis driving mechanism, the Y-axis driving mechanism, and the Z-axis driving mechanism 6, the screw locking mechanism 1 can use screws to lock the upper shell and the lower shell of the product to be screwed together. After the screw locking is completed, under the driving action of the rotating telescopic cylinder 31, the clamping plate 32 above the processing platform 2 moves upward for a distance and then rotates a certain angle (such as 90 degrees) to reset.

[0047] See also Figure 1 and Figure 3 When the conveyor belt 44 is conveying, the conveyor belt 44 drives the clamping block 45 to move linearly along the Y direction, the clamping block 45 drives the sliding part 46 to move linearly along the Y direction, and the sliding part 46 drives the processing platform 2 and the clamping component 3 to move linearly along the Y direction through the connecting plate 48.

In this way, two clamping components 3 are installed on each processing platform 2, and the two ends of the clamping plate 32 in one clamping component 3 can press the shells (upper shell and lower shell) of two products to be screwed into the two concave cavities 21 on the processing platform 2 respectively, and the two ends of the clamping plate 32 in the other clamping component 3 can press the shells (upper shell and lower shell) of the other two products to be screwed into the other two concave cavities 21 on the processing platform 2 respectively.

[0049] See also Figure 1 In this embodiment, the number of the accommodating cavities 51 on the processing platform 2, the clamping component 3, the Y-axis driving mechanism, and the base 5 are all two. One accommodating cavity 51 is used to accommodate the relevant components of one Y-axis driving mechanism, and the other accommodating cavity 51 is used to accommodate the relevant components of another Y-axis driving mechanism. One Y-axis driving mechanism drives one processing platform 2 and a clamping component 3 to make linear reciprocating movements along the Y direction, and the other Y-axis driving mechanism drives another processing platform 2 and another clamping component 3 to make linear reciprocating movements along the Y direction. The two processing platforms 2 are arranged in parallel. The clamping plate 32 of the clamping component 3 on one processing platform 2 can press the shells (upper shell and lower shell) of the two screw products to be locked into the two concave cavities 21 on the processing platform 2, and the clamping plate 32 of the clamping component 3 on the other processing platform 2 can press the shells (upper shell and lower shell) of the two screw products to be locked In the two concave cavities 21 on the processing platform 2; in this way, the two processing platforms 2 form two screw locking areas that do not interfere with each other, and the screw locking mechanism 1 can take turns to perform screw locking operations on the upper shells and the lower shells on the two processing platforms 2. When the screw locking operations on the upper shells and the lower shells on one processing platform 2 are completed, the screw locking mechanism 1 can immediately perform screw locking operations on the upper shells and the lower shells on the other processing platform 2. At this time, the operator can remove the product on the processing platform 2 that has completed the screw locking operation, and then place the new product to be screwed in the concave cavity 21 on the processing platform 2. In the process of removing the product that has completed the screw locking operation and placing the upper shell and the lower shell of the new product to be screwed, the operator does not need to force the screw locking mechanism 1 to stop working, so that the screw locking mechanism 1 can continuously perform screw locking operations on the upper shell and the lower shell, greatly improving work efficiency. In other embodiments, the number of accommodating cavities 51 on the processing platform 2, the clamping component 3, the Y-axis drive mechanism, and the base 5 can be adjusted according to the size of the base 5 and the processing requirements to ensure that a Y-axis drive mechanism drives a processing platform 2 and a clamping component 3 to move back and forth in a straight line along the Y direction.

[0050] See also Figures 1 to 3Two enclosures 52 are installed on the base 5, one enclosure 52 is surrounded by a wall around the opening at the top of one accommodating cavity 51, and the other enclosure 52 is surrounded by a wall around the opening at the top of another accommodating cavity 51. The enclosure 52 can prevent screws or other foreign objects from falling into the accommodating cavity 51.

[0051] See also Figure 3 , each accommodating cavity 51 is respectively installed with a sensing switch 511 at both ends along the length direction of the Y-direction slide rail 47. The sensing switch 511 can be a proximity switch or a micro switch. When the sliding portion 46 reciprocates along the Y-direction slide rail 47, when the sliding portion 46 moves to press against the sensing switch 511 at one end of the accommodating cavity 51, the motor 41 stops working to prevent the motor 41 from idling. When the sliding portion 46 moves to press against the sensing switch 511 at the other end of the accommodating cavity 51, the motor 41 stops working to prevent the motor 41 from idling. The setting of the sensing switch 511 can ensure that the sliding portion 46 moves back and forth in the accommodating cavity 51 accurately.

[0052] The X-axis driving mechanism, the motor 41, the Z-axis driving mechanism 6, the screw locking mechanism 1, the rotating and telescopic cylinder 31, and the induction switch 511 are all connected to the controller 8 through a harness. The controller 8 is installed on the base 5. The controller 8 can be a microcontroller or a single-chip microcomputer. The controller 8 can control the screw locking mechanism 1, the rotating and telescopic cylinder 31, the X-axis driving mechanism, the motor 41, and the Z-axis driving mechanism 6 to work together; when the sliding portion 46 moves to the induction switch 511 pressed against one end of the accommodating chamber 51, the induction switch 511 is triggered, and the induction switch 511 sends a trigger signal to the controller 8. The controller 8 controls the motor 41 to stop working to prevent the motor 41 from idling. When the sliding portion 46 moves to the induction switch 511 pressed against the other end of the accommodating chamber 51, the induction switch 511 is triggered, and the induction switch 511 sends a trigger signal to the controller 8. The controller 8 controls the motor 41 to stop working to prevent the motor 41 from idling.

[0053] See also Figure 1The automatic screw locking device of the utility model can align the upper shells and lower shells of four products to be screwed (such as remote controls) and place them in the four concave cavities 21 on the two processing platforms 2 respectively. Under the driving action of the rotating telescopic cylinder 31 of the pressing component 3, the pressing plate 32 above the processing platform 2 rotates 90 degrees and then moves downward for a distance to press laterally on the shells of the two products to be screwed, thereby pressing the shells into the concave cavities 21 on the processing platform 2, so that the upper shell and the lower shell of the shell are fixed together to prevent the two from shifting relative to each other during the screw locking process. Under the action of the X-axis driving mechanism, the Y-axis driving mechanism, and the Z-axis driving mechanism 6, the screw locking mechanism 1 can use screws to lock the upper shell and the lower shell of the product to be screwed together. After the screw locking is completed, under the driving action of the rotating telescopic cylinder 31, the pressing plate 32 above the processing platform 2 moves upward for a distance and then rotates 90 degrees to reset ( Figure 1 The state shown in the figure), the clamping component 3 of the utility model can automatically and quickly complete the clamping positioning and loosening and resetting of the shell of the product to be screwed, has a simple structure and high working efficiency. In addition, the two processing platforms 2 can form two screw locking areas that do not interfere with each other. The screw locking mechanism 1 can take turns to lock the upper shell and the lower shell on the two processing platforms 2. When the screw locking operation of the upper shell and the lower shell on one processing platform 2 is completed, the screw locking mechanism 1 can immediately lock the upper shell and the lower shell on the other processing platform 2. At this time, the operator can remove the product on the processing platform 2 that has completed the screw locking operation, and then place the upper shell and the lower shell of the new product to be screwed in the concave cavity 21 on the processing platform 2. In the process of removing the product that has completed the screw locking operation and placing the upper shell and the lower shell of the new product to be screwed, the operator does not need to force the screw locking mechanism 1 to stop working, so that the screw locking mechanism 1 can continuously lock the upper shell and the lower shell, thereby greatly improving the working efficiency.
