Description

Technical Field

[0001] The utility model relates to the technical field of thermostat part welding, in particular to a moving contact welding device for a moving contact piece of a thermostat. Background Art

[0002] At present, the moving contact piece and the moving contact of the thermostat are mostly fixed and welded manually, which not only has low efficiency, but also makes it difficult to unify the product quality. In response to this, there appears a welding device for the moving contact piece and the moving contact that can realize automation. For example, a Chinese patent document discloses a technical solution with a patent application number of 202123270466.8 and a name of "an automatic welding device for a contact and a contact point". This solution mainly consists of a welding bottom plate, a contact feeding device, a contact sorting device, a contact loading device, a welding positioning device, a welding lifting device, and a welding head device. During welding, first, the contact is placed between the welding positioning device and the welding head device through a turntable, then the contact is conveyed to the top surface of the contact through the contact feeding device, the contact sorting device, and the contact loading device, and finally, the contact and the contact point are clamped and welded by the welding positioning device and the welding head device to achieve the purpose of automatic welding. However, in the actual production and application process, there are still the following deficiencies:

[0003] First, the contact loading device mainly consists of a pneumatic gripper, a loading cylinder, and a material grasping positioning cylinder. The pneumatic gripper is driven by the loading cylinder and the material grasping positioning cylinder to move. After the pneumatic gripper grasps the contact, the contact moves in a suspended state. When the pneumatic gripper shakes due to the drive of the cylinder, the contact is very likely to loosen and fall off, resulting in some moving contact pieces not being welded together with the contact, and the probability of missed welding is relatively high, and the use reliability is poor.

[0004] Second, in this solution, the contacts are arranged with the contacts on top and the contacts on the bottom. When the pneumatic gripper is released and the contact is placed on the contact, the contact has a falling action, which is likely to cause the contact to shift. To solve the problem of contact displacement, this solution also sets positioning structures such as fixed positioning rods, movable positioning rods, and welding positioning cylinders on the welding positioning device. This not only has a complex structure, but also easily causes the contact to deform when the movable positioning rod presses against the contact, affecting the product quality.

[0005] Therefore, in view of the foregoing deficiencies in the existing moving contact welding device, the applicant believes that it is very necessary to further improve the existing solution so that it can better meet the production and application requirements. Summary of the Utility Model

[0006] The purpose of the present utility model is to solve the above problems and deficiencies, and to provide a moving contact welding device for a thermostat moving contact piece. During the process of transferring the moving contact, the moving contact is supported by the limiting guide groove and the movable end of the lower electrode driving mechanism, preventing the moving contact from falling, greatly reducing the probability of missed welding, and having very high use reliability. Moreover, during welding, the moving contact piece is arranged above and the moving contact is arranged below. The moving contact will not have a falling action, avoiding the situation of moving contact displacement, ensuring product quality, and the structure of the moving contact welding device is very simple, practical and reliable.

[0007] The technical solution of the present utility model is realized as follows: A moving contact welding device for a thermostat moving contact piece includes a moving contact conveying mechanism, a moving contact transferring mechanism, a moving contact piece conveying mechanism, an upper electrode driving mechanism and a lower electrode driving mechanism arranged oppositely up and down. The output end of the moving contact conveying mechanism is linked and cooperated with the movable end of the lower electrode driving mechanism through the moving contact transferring mechanism. Its characteristics are: The moving contact transferring mechanism includes a guide rail and a transferring component. The guide rail is provided with a limiting guide groove penetrating through both ends horizontally. One end of the limiting guide groove is communicated with the output end of the moving contact conveying mechanism, and the other end of the limiting guide groove faces the movable end of the lower electrode driving mechanism. The transferring component is slidably arranged in the limiting guide groove so that when the movable end of the lower electrode driving mechanism moves downward and its top surface is connected with the limiting guide groove to form a passage, the moving contact can be transferred to the top surface of the movable end of the lower electrode driving mechanism through the transferring component. The moving contact piece conveying mechanism is arranged between the upper electrode driving mechanism and the lower electrode driving mechanism, and the moving contact piece conveying mechanism is located above the moving contact transferring mechanism. The moving contact piece conveying mechanism is provided with a through hole for the movable ends of the upper electrode driving mechanism and the lower electrode driving mechanism to move in and out of its interior. When the movable end of the lower electrode driving mechanism moves upward, the moving contact is transferred into the through hole together, so that the moving contact and the moving contact piece are clamped and welded together.

[0008] Preferably, a moving contact positioning groove is further provided on the top surface of the movable end of the lower electrode driving mechanism.

[0009] Preferably, a moving contact magnetic attracting member is further provided on the groove wall of the limiting guide groove.

[0010] Preferably, the transferring component includes a transferring arm and a first driving cylinder. The transferring arm is fixed on the driving end of the first driving cylinder, so that the transferring arm slides on the limiting guide groove under the driving of the first driving cylinder.

[0011] Preferably, a moving contact frame taking groove is provided on the transferring arm.

[0012] The beneficial effects of the present utility model:

[0013] (1) Since the moving contact transfer mechanism of the present utility model includes a guide rail with a limit guiding groove and a transfer assembly, and the top surface of the movable end of the lower electrode driving mechanism can be connected with the limit guiding groove to form a passage. In this way, during the process of transferring the moving contact, the limit guiding groove and the movable end of the lower electrode driving mechanism support the moving contact, preventing the moving contact from falling, greatly reducing the probability of missed welding, and the reliability of use is very high.

[0014] (2) Since the moving contact piece transfer mechanism is located above the moving contact transfer mechanism, the moving contact piece can be arranged above and the moving contact can be arranged below. In this way, when the moving contact is transferred to the through hole, there will be no action of the moving contact falling, greatly avoiding the situation of the moving contact shifting, ensuring the product quality, and moreover, a moving contact positioning device can be not set, making the structure of the moving contact welding device simpler, more practical and reliable.

[0018] As Figure 1 shown, a moving contact welding device for a thermostat moving contact piece of the present utility model includes a moving contact transfer mechanism 1, a moving contact transfer mechanism 2, a moving contact piece transfer mechanism 3, an upper electrode driving mechanism 4 and a lower electrode driving mechanism 5 which are arranged up and down relatively. The output end of the moving contact transfer mechanism 1 is linked and cooperated with the movable end of the lower electrode driving mechanism 5 through the moving contact transfer mechanism 2; In order to achieve the purpose proposed by the present utility model, as Figure 2 and Figure 3As shown in the figure, the moving contact transfer mechanism 2 includes a guide rail 21 and a transfer assembly 22. The guide rail 21 is provided with a limit guide groove 211 that runs horizontally through both ends thereof. One end of the limit guide groove 211 is connected to the output end of the moving contact transmission mechanism 1, and the other end of the limit guide groove 211 faces the movable end of the lower electrode driving mechanism 5. The transfer assembly 22 is slidably disposed in the limit guide groove 211 so that when the movable end of the lower electrode driving mechanism 5 moves downward and its top surface is connected to the limit guide groove 211 to form a passage, the moving contact can be transferred to the top surface of the movable end of the lower electrode driving mechanism 5 through the transfer assembly 22. The moving contact piece transmission mechanism 3 is disposed between the upper electrode driving mechanism 4 and the lower electrode driving mechanism 5, and the moving contact piece transmission mechanism 3 is located above the moving contact transfer mechanism 2. The moving contact piece transmission mechanism 3 is provided with a through hole 33 for the movable ends of the upper electrode driving mechanism 4 and the lower electrode driving mechanism 5 to move in and out of its interior. When the movable end of the lower electrode driving mechanism 5 moves upward, the moving contact is transferred into the through hole 33 together, so that the moving contact and the moving contact piece are clamped and welded together. During the process of transferring the moving contact in the present utility model, the limit guide groove 211 and the movable end of the lower electrode driving mechanism 5 support the moving contact to prevent the moving contact from falling, greatly reducing the probability of missed welding, and the use reliability is very high. Moreover, during welding, the moving contact piece is arranged above and the moving contact is arranged below, and there is no action of the moving contact falling, avoiding the situation of moving contact displacement, ensuring product quality, and the structure of the moving contact welding device is very simple, practical and reliable.

[0019] As Figure 2 shown, a moving contact positioning groove 511 is further provided on the top surface of the movable end of the lower electrode driving mechanism 5. This can play a role in restricting and positioning the moving contact, preventing the moving contact from swaying randomly, and thus can further prevent the moving contact from falling from the movable end of the lower electrode driving mechanism 5, which is very practical and reliable.

[0020] In order to enable the moving contact to accurately move into the limit guide groove 211, as Figure 3 shown, a moving contact magnetic attracting member 212 is further provided on the groove wall of the limit guide groove 211. Specifically, the moving contact magnetic attracting member 212 is a magnet. This can enable the moving contact to quickly and accurately move into the limit guide groove 211, ensuring that the transfer assembly 22 can transfer the moving contact very smoothly without jamming.

[0021] In order to make the structure of the transfer assembly 22 simple and easy to implement, as Figure 2As shown, the transfer assembly 22 includes a transfer arm 221 and a first driving cylinder 222. The transfer arm 221 is fixed to the driving end of the first driving cylinder 222, so that under the drive of the first driving cylinder 222, the transfer arm 221 slides on the limit guiding groove 211. Through the setting of the first driving cylinder 222, the transfer arm 221 can slide back and forth on the limit guiding groove 211, so as to transfer each moving contact to the movable end of the lower electrode driving mechanism 5 one by one.

[0022] To prevent the moving contact from falling out of the limit guiding groove 211 during the transfer process, as Figure 3 shown, a moving contact frame-taking groove 223 is provided on the transfer arm 221. Through the setting of the moving contact frame-taking groove 223, the moving contact in the limit guiding groove 211 can be framed, so that during the transfer process, the moving contact can be prevented from falling out of the limit guiding groove 211, and the transfer is more reliable. In the actual application process, the moving contact transfer mechanism 1 transfers the moving contact to the limit guiding groove 211 in the longitudinal direction, and the moving contact frame-taking groove 223 is longitudinally penetrated through the transfer arm 221. To enable the transfer arm 221 to frame moving contacts of different sizes and types, as Figure 3 shown, a detachable T-shaped frame-taking part is provided on the transfer arm 221, and the moving contact frame-taking groove 223 is opened on the T-shaped frame-taking part. In this way, according to moving contacts of different sizes and types, the T-shaped frame-taking part with the corresponding size and type of moving contact frame-taking groove 223 can be replaced.

[0023] To make the structure of the upper electrode driving mechanism 4 simple and easy to implement, as Figure 2 shown, the upper electrode driving mechanism 4 includes an upper electrode 41 and a second driving cylinder 42, and the upper electrode 41 is arranged on the driving end of the second driving cylinder 42. To make the structure of the lower electrode driving mechanism 5 simple and easy to implement, as Figure 2 shown, the lower electrode driving mechanism 5 includes a lower electrode 51 and a third driving cylinder 52, and the lower electrode 51 is arranged on the driving end of the third driving cylinder 52. During welding, by clamping the moving contact and the moving contact piece between the upper electrode 41 and the lower electrode 51, the moving contact and the moving contact piece can be welded.

[0024] To make the structure of the moving contact transfer mechanism 1 simple and easy to implement, as Figure 1As shown in the figure, the moving contact transmission mechanism 1 includes a vibrating bowl 11 with a discharge end and a moving contact feeding rod 12 with a moving contact feeding groove. The moving contact feeding rod 12 is respectively connected to the vibrating bowl 11 and the guide rail 21. The input end of the moving contact feeding groove is communicated with the discharge end of the vibrating bowl 11, and the output end of the moving contact feeding groove is communicated with one end of the limit guiding groove 211. When transmitting the moving contacts, each moving contact enters the discharge end in sequence through the vibration of the vibrating bowl 11, and then enters the moving contact feeding groove of the moving contact feeding rod 12 from its discharge end, so as to realize the transmission of each moving contact.

[0025] In order to make the structure of the moving contact piece transmission mechanism 3 simple and easy to implement, as Figure 1 shown in the figure, the moving contact piece transmission mechanism 3 includes a moving contact piece feeding guide rod 31 and a transmission roller. The moving contact piece feeding guide rod 31 is provided with a moving contact piece feeding groove 311. The transmission roller is rotatably arranged in the moving contact piece feeding groove 311. The through hole 33 is arranged on the moving contact piece feeding guide rod 31 and is communicated with the moving contact piece feeding groove 311. In the actual application process, when each moving contact piece is not cut out separately, it is in a strip-shaped structure of a strip of material. When transmitting, by the transmission roller rollingly contacting with the strip of material, the strip of material can be driven to move in the moving contact piece feeding groove 311, so as to realize the transmission of each moving contact piece. In actual application, in order to prevent the strip of material from running out of the moving contact piece feeding groove 311, as Figure 1 shown in the figure, a limit baffle 32 is further arranged on the moving contact piece feeding guide rod 31, and the limit baffle 32 covers the upper notch of the moving contact piece feeding groove 311. In this way, it can play a role in limiting the strip of material, avoiding the strip of material from running out of the moving contact piece feeding groove 311 and preventing the transmission from getting stuck. In the actual application process, the transmission roller is driven by a motor to rotate.
