Description
Technical Field
[0001] The utility model relates to the technical field of loudspeaker product processing, and in particular to a mounting fixture for detecting a sounder. Background Art
[0002] At present, the common loudspeaker / sound device products on the market often need to be tested for various performance standards after the production and processing are completed. The testing mainly involves acoustic performance testing, circuit conductivity performance testing and product appearance and size testing. The testing process generally adopts manpower or semi-automatic testing processes with more manpower participation. However, the common testing processes on the market have low testing efficiency and are prone to operational errors such as misplacing qualified products with unqualified finished products due to a large amount of repetitive work by operators. In order to solve this situation, in order to improve the production efficiency of speakers and reduce the detection error rate, the finished product testing is optimized by automated design.
[0003] In this regard, the inventors have proposed some practical designs of highly automated inspection lines. However, in actual experiments and simulation applications, it was found that: since product inspection generally includes multiple different inspection processes and involves several different inspection devices / inspection stations, in order to ensure the degree of automation of the inspection process, conveyor belts, manipulators and other structures are set up to transfer the sounder products to be inspected between different stations, and place the sounders in the correct position and posture to ensure the smooth implementation of product inspection.
[0004] However, in fact, the commonly used transfer devices between working processes have the following problems: first, the clamping action of the robot may damage the external structure of the product, causing scratches and deformation, and second, it may accidentally touch the contact structure on the product, causing the position of the contact structure to shift and resulting in poor conduction performance of the product; in addition, the finished product transfer using a mechanical structure is often difficult to ensure that the position and posture of the product to be inspected are accurate when it arrives at the designated position, and often requires the use of a positioning structure or manual assistance to ensure the continuity of the inspection process, which requires the addition of a large number of auxiliary devices to the automated inspection equipment, resulting in high implementation costs.
[0005] In summary, the existing sounder finished product inspection process has technical problems such as easy damage to the product and difficulty in maintaining the correct position during automation optimization. Utility Model Content
[0006] The technical problem to be solved by the utility model is that the existing sounder finished product detection process has the technical problems of being easy to damage the product and difficult to keep it in the correct position during the automation optimization.
[0007] To solve the above problems, the utility model provides a mounting fixture for sounder detection, including a placement seat, the placement seat is a flat pier in the shape of a polygonal prism, a receiving groove for placing the sounder product to be detected is arranged in the middle of the placement seat, the inner edge shape of the receiving groove is matched with the outer edge shape of the sounder product to be detected, and is used to position the sounder product to be detected and the placement seat at a preset relative angle; the outer edge of the placement seat is used to clamp and cooperate with the clamping and transferring device of the automatic detection equipment, and the posture angle of the clamping placement seat is calibrated by the polygonal prism structure of its outer edge.
[0008] The utility model provides a carrying fixture for carrying a sounder product to be tested during the entire quality inspection process. The overall shape is a prismatic flat pier to ensure that the center of gravity is biased downward. When used in conjunction with a conveyor belt or other structure for transportation, the posture can be kept stable. The prismatic peripheral structure itself is convenient for accurately positioning the clamping posture angle of the carrying fixture with a clamping manipulator structure, so that the posture angle can be adapted to the execution device of the detection during the inspection. The placement seat has a receiving groove whose shape matches the outer contour of the sounder to be tested. Through such a design, the relative angle between the carried sounder and the carrying fixture is kept fixed, so that the angle posture of the product to be tested can be kept accurate during the transfer process between various detection processes. In addition, due to the setting of the carrying fixture, during the transfer process of the product to be tested, the auxiliary transfer fixing structures such as the fixture manipulator do not directly act on the product shell, but operate the carrying fixture, which effectively protects the sounder product structure. In summary, the carrying fixture for sounder detection provided by the utility model effectively solves the technical problems that the product is easily damaged and difficult to maintain the correct position during the automation optimization of the existing sounder finished product detection process.
[0009] As a preferred solution, the placement seat is a square column structure, and the two adjacent side surfaces of its outer edge are provided with concave conical clamping openings to assist the clamping action of the clamping transfer device. This design optimizes the overall external shape of the placement seat. The outer shape of the square column placement seat further facilitates the determination of the angle of the carrier. In addition, concave conical clamping openings are provided on both sides of the placement seat, mainly to facilitate the stable clamping of the carrying fixture with the commonly used three-claw manipulator, where two claws correspond to clamping the two conical clamping openings respectively, and the other claw corresponds to one side of the outer side of the placement seat.
[0010] As a preferred solution, the receiving groove runs through the height direction of the placement seat, and the receiving groove is provided with a step surface structure at one end opening position for placing the sounder product, which is used to support the sounder product to be detected placed in the receiving groove at a preset height. This design sets a step surface structure at the edge of the upper opening position of the receiving groove. Through such a structure, the opening of the receiving groove is larger relative to the internal diameter, which first facilitates the placement of the sounder into the receiving groove, and such a step surface structure can be accurately stuck on the outer edge of the sounder after the sounder is placed, so that the placement height of the sounder to be detected in the placement seat is accurate, which is convenient for the detection process with relatively precise movements.
[0011] As a preferred solution, two opposite sides of the outer edge of the receiving groove are provided with clamping grooves, and the two ends of the clamping grooves are respectively connected to the receiving groove and the outer edge of the placement seat, and the groove depth of the clamping grooves is less than the groove depth of the receiving groove. This design optimizes the matching structure design of the receiving groove, and a pair of clamping grooves with opposite positions are provided on its periphery. After the sounder product is placed in the receiving groove, the outer side of the sounder is exposed to the opening position of the clamping groove, which is convenient for inserting or removing the sounder product into the receiving groove through this structure.
[0012] As a preferred solution, the receiving groove is provided with an additional groove parallel to its depth direction, and the additional groove protrudes from the outer edge contour of the receiving groove, and is used to reserve a protective space corresponding to the label position on the sounder product to be detected. This design further optimizes the structural design in the receiving groove. Since the outer side of the sounder is generally provided with a label containing product number information, in order to avoid scratching the product label during the process of taking the sounder from the carrier, an additional groove is provided in the receiving groove parallel to the depth direction of the receiving groove, that is, the direction of taking and placing the sounder product. The position of the additional groove corresponds to the label on the outside of the product, so that the label does not touch the wall of the receiving groove, providing effective protection.
[0013] As a preferred solution, the top surface of the placement seat is provided with positioning holes perpendicular to its end surface around the receiving groove, which are used to cooperate with the positioning shaft on the detection device to position the angle of the placement seat, and the positioning holes are cylindrical or conical with a preset taper. This design optimizes the posture positioning design of the placement seat, and more than two positioning holes are provided on it. The positioning structure only needs to cooperate with the positioning shaft structure in the detection device to accurately position, which greatly simplifies the corresponding structure.
[0014] As a preferred solution, the top surface of the placement seat is provided with a recessed label groove at a preset distance from the receiving groove, and the label groove is used to set a number label marking the corresponding placement seat. The design principle refers to the above-mentioned additional groove structure, and a label groove is also provided on the top surface of the placement seat, and the label corresponding to the placement seat can be placed in the label groove. Similarly, it is convenient to protect the label to avoid scratches and unrecognizable, and to easily and accurately match the placement seat with the sounder product one by one. This is mainly because after the sounder product is placed in the receiving groove, the product label on it is hidden and difficult to read and identify during the detection process. Therefore, a label is also provided on the placement seat to make it correspond one by one with the product label, and the corresponding sounder product can be identified by the label on the placement seat.

[0027] The utility model provides a carrying fixture for carrying a sounder product to be tested during the entire quality inspection process. The overall shape is a prismatic flat pier to ensure that the center of gravity is biased downward. When used in conjunction with a conveyor belt or other structure for transportation, the posture can be kept stable. The prismatic peripheral structure itself is convenient for accurately positioning the clamping posture angle of the carrying fixture with a clamping manipulator structure, so that the posture angle can be adapted to the execution device of the detection during the inspection.

Through such a design, the relative angle between the carried sounder and the carrying fixture is kept fixed, so that the angle posture of the product to be tested can be kept accurate during the transfer process between various detection processes. In addition, due to the setting of the carrying fixture, during the transfer process of the product to be tested, the auxiliary transfer fixing structures such as the fixture manipulator do not directly act on the product shell, but operate the carrying fixture, which effectively protects the sounder product structure. In summary, the carrying fixture for sounder detection provided by the utility model effectively solves the technical problems that the product is easily damaged and difficult to maintain the correct position during the automation optimization of the existing sounder finished product detection process.
[0028] In the technical solution provided in this embodiment, the placement seat 1 is a square column structure, and the two adjacent side surfaces of its outer edge are provided with concave conical clamping openings 4 to assist the clamping action of the clamping transfer device. This design optimizes the overall external shape of the placement seat 1. The outer shape of the square column placement seat 1 further facilitates the determination of the angle of the carrier. In addition, the concave conical clamping openings 4 are provided on both sides of the placement seat 1, mainly to facilitate the stable clamping of the carrying fixture with the commonly used three-claw manipulator, in which two claws correspond to the two conical clamping openings 4 respectively, and the other claw corresponds to the outer side surface of one side of the placement seat 1.
[0029] In the technical solution provided by this embodiment, the receiving groove 2 runs through the height direction of the placement seat 1, and the receiving groove 2 is provided with a step surface structure 6 at one end opening position for placing the sounder product 9, which is used to support the sounder product 9 to be detected placed in the receiving groove 2 at a preset height. This design sets a step surface structure 6 at the edge of the upper opening position of the receiving groove 2. Through such a structure, the opening of the receiving groove 2 is larger relative to the internal diameter, which first facilitates the placement of the sounder into the receiving groove 2, and such a step surface structure 6 can be accurately stuck on the outer edge of the sounder after the sounder is placed, so that the placement height of the sounder to be detected in the placement seat 1 is accurate, which is convenient for the detection process with relatively precise movements.
[0030] In the technical solution provided in this embodiment, clamping grooves 3 are arranged on opposite sides of the outer edge of the receiving groove 2, and the two ends of the clamping grooves 3 are respectively connected to the receiving groove 2 and the outer edge of the placement seat 1, and the groove depth of the clamping grooves 3 is less than the groove depth of the receiving groove 2. This design optimizes the matching structure design of the receiving groove 2, and a pair of clamping grooves 3 with opposite positions are arranged on its periphery. After the sounder product 9 is placed in the receiving groove 2, the outer side of the sounder is exposed to the opening position of the clamping grooves 3, which is convenient for inserting or removing the sounder product 9 into the receiving groove 2 through this structure.

This design further optimizes the structural design in the receiving groove 2. Since the outer side of the sounder is generally provided with a label containing product number information, in order to avoid scratching the product label during the process of taking the sounder from the carrier, an additional groove 8 is provided in the receiving groove 2 parallel to the depth direction of the receiving groove 2, that is, the direction of taking and placing the sounder product 9. The position of the additional groove 8 corresponds to the label on the outside of the product, so that the label does not touch the wall of the receiving groove 2, providing effective protection.
