Description

Technical Field

[0001] This utility model belongs to the field of intelligent manufacturing equipment technology, specifically relating to a workpiece cleaning device for an intelligent fully automatic assembly machine for motor starter protectors. Background Technology

[0002] The aforementioned motor starter protector is a general term for a product that integrates a motor starter and a motor protector into a single housing, i.e., a two-in-one product. The aforementioned workpiece essentially refers to the motor starter protector housing (hereinafter referred to as the "housing"), the function of which can be found, but is not limited to, the Chinese patent CN204442206U (Energy-saving Single-phase AC Motor Starter Protector). Furthermore, regarding the specific structure and function of the motor starter protector, in addition to the aforementioned CN204442206U, see also CN100581043A (Energy-saving Integrated Single-phase AC Motor Starter Protector), and so on.

[0003] Because motor starter protectors have a relatively large number of components and the installation quality requirements are extremely stringent, especially due to the previous lack of dedicated automated assembly machinery, a large number of assembly workers had to assemble them manually. This production mode is defined as labor-intensive production. Producing motor starter protectors in a labor-intensive manner is unacceptable to manufacturers from both quality and cost perspectives. This is particularly true in recent years, as labor resources have become increasingly scarce and labor costs have continued to rise, forcing manufacturers of motor starter protectors to focus on exploring intelligent, fully automated assembly equipment. The utility model patent applications CN106670803A (Automatic Assembly Device for Protector with Protector Base Extraction and Release Function) and CN113714455A (Rivet Fastening Structure of Automated Assembly Device for Current Starter) filed by the applicant are examples of this.

[0004] Because the internal components of electronic and electrical products are highly demanding in terms of cleanliness, in the case of the housing described above, all components, such as the base, fixed seat, moving contact, stationary contact, insert, bimetallic strip, bimetallic strip support ring, push rod, and heating wire of the motor protector's structural system, and the positive temperature coefficient thermistor, a pair of pin springs, and a pair of pins of the motor starter's structural system, are all assembled in their respective positions within the housing. Therefore, if the housing cavity is not sufficiently cleaned during the manufacturing process, it will inevitably affect some relatively "delicate" components. For example, the aforementioned bimetallic strip is a heat-sensitive element with extremely high operational precision requirements. Any residual dust, debris left in the housing cavity during the molding process, or external dust that enters the housing cavity during logistics and warehousing, etc., may become stuck in the bimetallic strip's movement gap or adhere to its surface after assembly, causing changes in its thermal deformation properties, increased operating resistance, or even complete jamming, resulting in product malfunction.

[0005] As mentioned above, from the perspective of ensuring electrical safety and long-term reliability, if the housing is not cleaned during assembly, in addition to the disadvantages mentioned above regarding the bimetallic strip, it may also lead to potential short-circuit risks in other components. Therefore, cleaning the housing can improve the service life and long-term reliability of the motor starter protector. Furthermore, it can ensure that the aforementioned components are installed smoothly and accurately, avoiding "false positioning," jamming, or abnormal assembly force caused by foreign object interference.

[0011] In another specific embodiment of this utility model, the housing cavity of the housing faces upward; the air outlet of the blowing pipe and the dust suction port of the suction pipe are positioned in an inverted V-shape above the housing cavity of the housing.

[0012] The technical effect of the solution provided by this utility model is that the air blowing pipe blows the shell cavity of the housing, and at the same time the dust suction pipe removes the dust blown up by the air blowing pipe, thereby helping to effectively clean the housing, avoiding the dust and debris remaining in the shell cavity from affecting the assembly quality, and avoiding the impact on the electrical performance characteristics of the assembled electrical components, thus ensuring the expected service life of the motor starter protector product within a reasonable period.

[0018] See you later Figure 1 On the upward-facing edge of the aforementioned rotary table 11, and at equal intervals around the circumference of the rotary table 11, a housing support mold 111 is provided. The housing 3 is input via a housing input track (not shown in the figure) and extracted and released onto the support mold 111 by a housing extraction and release mechanism (also not shown in the figure) mounted on the worktable 1. The aforementioned dust removal frame 21 includes a suction pipe seat fixing plate 211 and an air blowing pipe seat fixing plate 212. The suction pipe seat fixing plate 211 is... The vacuum tube holder fixing plate 211 is set in a longitudinal position and its lower end is fixed to the vacuum tube holder fixing plate support 2111.
