Description

Technical Field

[0001] This invention relates to the field of testing technology, and more specifically to a device for testing the peel function of electronic product packaging. Background Technology

[0002] Electronic product packaging involves a variety of materials, with cardboard packaging being the most common. Figure 1 The diagram shows a multi-layer cardboard structure for electronic product packaging in the prior art. This structure includes a top cardboard 2, a bottom cardboard 3, and a connecting cardboard 4. The two ends of the connecting cardboard 4 are bonded to the top cardboard 2 and the bottom cardboard 3. During the production of this multi-layer cardboard structure, a tensile test is required to determine the adhesion strength, i.e., a peel strength test. Currently, tensile testing of multi-layer cardboard is mostly performed manually by pulling the cardboard, which is time-consuming and labor-intensive, and cannot be automated mechanically. Summary of the Invention

[0003] The main objective of this invention is to provide a peel function testing device for electronic product packaging, in order to solve the problem in the prior art that it is impossible to achieve mechanical automation in testing the peel function of electronic product packaging cardboard.

[0004] To achieve the above objectives, the present invention provides a peel-off function testing device for electronic product packaging, comprising a multi-section robotic arm, a conveyor belt, a mobile testing mechanism, and a fixed testing mechanism.

[0005] A mobile detection mechanism is fixedly mounted on a multi-segment robotic arm;

[0006] The conveyor belt is used to transport multi-layer cardboard, and a fixed detection mechanism is fixedly installed on one side of the conveyor belt;

[0007] Both the mobile testing mechanism and the fixed testing mechanism include a frame and a ventilation pipe. The frame of the mobile testing mechanism is fixedly mounted on a multi-section robotic arm, while the frame of the fixed testing mechanism is fixedly mounted on one side of the conveyor belt.

[0008] There are multiple air ducts, all of which are fixedly mounted on the frame and arranged in a matrix on the frame. All of the multiple air ducts are connected to an adsorption plate, and the ends of the multiple adsorption plates furthest from the air ducts are located on the same plane.

[0009] A preferred embodiment is that the frame includes a main board, square tubes and a support plate, with two square tubes, both of which are fixedly mounted on the main board in parallel. The main board is fixedly mounted on one side of the multi-section robotic arm or conveyor belt.

[0010] The number of ventilation pipes in the mobile detection mechanism is the same as the number of support plates. One end of each support plate is fixedly connected to a square tube, and the other end of each support plate is equipped with a ventilation pipe.

[0011] A preferred embodiment is that the outer ring wall of the vent pipe is threaded, the support plate is grooved along its length, the vent pipe passes through the groove, the threaded section is screwed with a nut, the vent pipe is fitted with a compression spring and a ring, one end of the compression spring abuts against the adsorption plate, the other end of the compression spring abuts against the ring, and the ring and nut are located on both sides of the support plate.

[0012] A preferred embodiment is that the adsorption plate includes an annular shell and a flexible cylinder, one end of the annular shell is connected to a vent pipe, the other end of the annular shell is connected to the flexible cylinder, and the end of the compression spring away from the annular body abuts against the annular shell.

[0013] A preferred option is that the flexible cylinder is made of rubber.

[0014] A preferred embodiment also includes a pressure detection mechanism, which is mounted on the mobile detection mechanism;

[0015] The pressure testing mechanism includes a pressure testing body and a vertical drive mechanism. The vertical drive mechanism is fixedly mounted on the frame of the mobile testing mechanism. The vertical drive mechanism is used to drive the pressure testing body to move along the axis of the air pipe of the pressure testing mechanism. The pressure testing body is used to test the compressive strength of multi-layer cardboard.

[0016] A preferred embodiment is that the vertical driving mechanism is a cylinder, the cylinder seat is fixedly mounted on the frame of the moving detection mechanism, and the piston rod of the cylinder is fixedly connected to the pressure detection body.

[0017] The pressure detection unit includes a guide rail, a threaded rod, and a drive component for rotating the threaded rod. The guide rail is fixedly mounted on the piston rod of the cylinder, and the threaded rod is rotatably mounted inside the guide rail. One end of the threaded rod has a left helical section, and the other end has a right helical section. Both the left and right helical sections are screwed with moving blocks, and both moving blocks are slidably mounted on the guide rail and abut against the multi-layer cardboard.

[0018] A preferred solution is to equip both moving blocks with pressure sensors.

[0019] A preferred embodiment is that the driving component is a motor, the motor's base is fixedly connected to the guide rail, and the motor's output shaft is coaxially connected to the threaded rod.

[0020] The beneficial effects of the above scheme are as follows: First, a conveyor belt holds multiple multi-layer cardboard sheets, which are then transported to one side of a multi-section robotic arm. The robotic arm moves a mobile detection mechanism, which in turn moves multiple suction cups directly above a single multi-layer cardboard sheet, driving the suction cups on the mobile detection mechanism to work. Further, the robotic arm moves the single multi-layer cardboard sheet until it is directly above the suction cups of a fixed detection mechanism, driving the suction cups of the fixed detection mechanism to work. The mobile and fixed detection mechanisms, along with their suction cups, perform suction on the single multi-layer cardboard sheet. The robotic arm then moves the mobile detection mechanism away from the fixed detection mechanism, subjecting the single multi-layer cardboard sheet to vertical tension for peeling detection. This determines whether the multi-layer cardboard sheet is qualified. This structure achieves automated mechanical testing of the vertical tension of multi-layer cardboard sheets.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0030] First embodiment:

[0031] like Figures 1 to 5 As shown, this embodiment provides a peel function testing device for electronic product packaging, including a multi-segment robotic arm 10, a conveyor belt 30, a moving testing mechanism 20, and a fixed testing mechanism 40. The moving testing mechanism 20 is fixedly mounted on the multi-segment robotic arm 10. The conveyor belt 30 is used to transport multi-layer cardboard 1, and the fixed testing mechanism 40 is fixedly mounted on one side of the conveyor belt 30. Both the moving testing mechanism 20 and the fixed testing mechanism 40 include a frame 50 and ventilation pipes 51. The frame 50 of the moving testing mechanism 20 is fixedly mounted on the multi-segment robotic arm 10, and the frame 50 of the fixed testing mechanism 40 is fixedly mounted on one side of the conveyor belt 30. Multiple ventilation pipes 51 are fixedly mounted on the frame 50 and arranged in a matrix on the frame 50. Each ventilation pipe 51 is connected to an adsorption plate 52, and the ends of the adsorption plates 52 furthest from the ventilation pipes 51 are located on the same plane.

[0032] First, the conveyor belt 30 places multiple multi-layer cardboard 1s. The conveyor belt 30 transports the multi-layer cardboard 1s to one side of the multi-section robotic arm 10. The multi-section robotic arm 10 drives the moving detection mechanism 20 to move its position. The moving detection mechanism 20 moves multiple suction cups 52 to a position directly above a single multi-layer cardboard 1, driving the multiple suction cups 52 on the moving detection mechanism 20 to work. Further, the multi-section robotic arm 10 drives the single multi-layer cardboard 1 to move its position until the single multi-layer cardboard 1 moves to a position directly above the suction cups 52 of the fixed detection mechanism 40, driving the suction cups 52 of the fixed detection mechanism 40 to work. The moving fixed detection mechanism 40 and the suction cups 52 of the fixed detection mechanism 40 perform a suction action on the single multi-layer cardboard 1. The multi-section robotic arm 10 drives the moving detection mechanism 20 to move away from the position of the fixed detection mechanism 40, and the single multi-layer cardboard 1 is subjected to vertical tension detection. Then, it is determined whether the multi-layer cardboard 1 is qualified. Through this structure, mechanical automation is achieved for the vertical tension detection of the multi-layer cardboard 1.

[0033] Second embodiment:

[0034] The frame 50 includes a main board 53, square tubes 54, and support plates 55. There are two square tubes 54, both fixedly mounted parallel to each other on the main board 53. The main board 53 is fixedly mounted on one side of the multi-section robotic arm 10 or conveyor belt 30. The number of air ducts 51 in the moving detection mechanism 20 is the same as the number of support plates 55. One end of each support plate 55 is fixedly connected to a square tube 54, and the other end of each support plate 55 is equipped with an air duct 51. This defines the structure of the frame 50.

[0035] A threaded section 510 is formed on the outer circumference of the vent pipe 51. A groove 550 is formed along the length of the support plate 55. The vent pipe 51 passes through the groove 550. A nut 56 is screwed onto the threaded section 510. A compression spring 57 and a ring 58 are fitted onto the vent pipe 51. One end of the compression spring 57 abuts against the adsorption plate 52, and the other end of the compression spring 57 abuts against the ring 58. The ring 58 and the nut 56 are located on both sides of the support plate 55.

[0036] The arrangement of one end of the compression spring 57 abutting against the adsorption disk 52 and the other end of the compression spring 57 abutting against the ring body 58 provides a buffering effect on the adsorption disk 52 when gripping or pulling the multi-layer cardboard 1.

[0037] The adsorption plate 52 includes an annular shell 520 and a flexible cylinder 521. One end of the annular shell 520 is connected to the vent pipe 51, and the other end of the annular shell 520 is connected to the flexible cylinder 521. The end of the compression spring 57 away from the ring body 58 abuts against the annular shell 520.

[0038] The flexible cylinder 521 is made of rubber.

[0039] Third embodiment:

[0040] The peel function testing equipment for electronic product packaging also includes a pressure testing mechanism 60, which is mounted on the movable testing mechanism 20.

[0041] like Figure 5 As shown, the pressure testing mechanism 60 includes a pressure testing body 61 and a vertical driving mechanism 62. The vertical driving mechanism 62 is fixedly mounted on the frame 50 of the movable testing mechanism 20. The vertical driving mechanism 62 is used to drive the pressure testing body 61 to move along the axis of the vent pipe 51 of the pressure testing mechanism 60. The pressure testing body 61 is used to test the compressive strength of the multilayer cardboard 1.

[0042] The vertical drive mechanism 62 is a cylinder. The cylinder seat is fixedly mounted on the frame 50 of the moving detection mechanism 20, and the piston rod of the cylinder is fixedly connected to the pressure detection body 61.

[0043] The pressure detection body 61 includes a guide rail 610, a threaded rod 611, and a drive component 612 for rotating the threaded rod 611. The guide rail 610 is fixedly mounted on the piston rod of the cylinder, and the threaded rod 611 is rotatably mounted inside the guide rail 610. One end of the threaded rod 611 has a left helical segment 613, and the other end of the threaded rod 611 has a right helical segment 614. Both the left helical segment 613 and the right helical segment 614 are screwed with moving blocks 615. Both moving blocks 615 are slidably mounted on the guide rail 610 and abut against the multilayer cardboard 1.

[0044] Both moving blocks 615 are equipped with pressure sensors.

[0045] The driving component 612 is a motor, the motor base is fixedly connected to the guide rail 610, and the output shaft of the motor is coaxially connected to the threaded rod 611.

[0046] The movable fixed detection mechanism 40 and the suction plate 52 of the fixed detection mechanism 40 adsorb a single multi-layer cardboard 1. The multi-section robotic arm 10 drives the movable detection mechanism 20 to move away from the fixed detection mechanism 40. The single multi-layer cardboard 1 is subjected to vertical tension detection. In this way, the multi-layer cardboard 1 is subjected to longitudinal tension detection. After the longitudinal tension detection is completed, the suction plate 52 of the fixed detection mechanism 40 stops working, and the drive motor works. The motor drives the threaded rod 611 to rotate. Through the left helical section 613, the other end of the threaded rod 611 has a right helical section 614, which makes the two moving blocks 615 move to the center position in the length direction of the threaded rod 611 until the two moving blocks 615 complete the clamping of the single multi-layer cardboard 1. Further, the multi-section robotic arm 10 is driven to move. Through the clamping effect of the suction plate 52 on the movable detection mechanism 20 and the two moving blocks 615 on the multi-layer cardboard 1, the multi-layer cardboard 1 is separated from the suction plate 52 of the fixed detection mechanism 40. Through the structural design of the pressure detection mechanism 60, the single multi-layer cardboard 1 is prevented from being stuck on the fixed detection mechanism 40. The suction cup can easily adhere to the cardboard due to the adsorption force. The clamping effect can achieve clamping and fixing instead of the adsorption function of the suction cup. Thus, the clamping structure has two effects: clamping and fixing on one hand, and it can also be used for later pressure testing of the side of the cardboard on the other hand.

[0047] In addition, the pressure detection mechanism 60 is designed with two moving blocks 615 moving towards the cardboard until they clamp the multi-layer cardboard 1. Pressure sensors are then used to detect the bending pressure on a single multi-layer cardboard 1. Alternatively, the moving position of the moving blocks 615 can be determined by controlling the screw rod 611, and the pressure exerted by the contact between the moving blocks and the cardboard 1 can be determined by the driving force of the motor. This controlled sensing method obtains the pressure on the cardboard, and then tests its compressive strength to determine compliance.

[0048] This invention enables automated mechanical testing of longitudinal tensile strength and transverse bending resistance of multi-layer cardboard 1, greatly improving the efficiency of cardboard testing.

[0049] Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
