Description

Technical Field

[0001] The utility model relates to the technical field of assembly machines, in particular to an assembly machine for a thermal protector. Background Art

[0002] A thermal protector is a thermostat made of two different alloys. When the temperature drops to the set temperature, the contacts automatically close / open and resume normal working state. It is widely used in household electrical motors and electrical equipment, such as washing machine motors, air conditioner fan motors, transformers, ballasts, electric heating appliances, etc. Since the thermal protector has a relatively simple structure, it is usually assembled automatically using a special assembly machine.

[0003] Today's assembly machines usually use a vibration plate to load the various components of the thermal protector separately, use an insulating sheet feeding mechanism to achieve automatic forming and loading of the insulating sheet, automatically close and press through a closing mechanism and a pressing mechanism, and finally automatically unload the finished product through a collecting mechanism. The equipment has a high degree of automation and high processing efficiency.

[0004] However, the mechanisms responsible for feeding, such as the automatic feeding vibration plate, the insulating sheet feeding mechanism, etc., may fail to feed successfully or the feeding may be offset due to some unexpected reasons or their own problems during a certain feeding process, making it difficult to complete the subsequent assembly work normally. At this time, if the mechanisms continue to operate, energy will be wasted, and due to the lack of corresponding material obstruction, the assembly equipment may directly contact the carrier or other structures, causing damage to the equipment working head. Therefore, a thermal protector assembly machine is proposed to address the above problems. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a thermal protector assembly machine, which is provided with material sensing frames in the gaps between the various parts of the feeding part and the gaps between the feeding part and the pressing part. The material sensing frame plays a material detection role through the combined work of the transmitting head and the receiving head thereon, and can detect the placement of the material in the fixture before proceeding to the next step. If the material is in the correct position in the fixture, it can play a blocking role, blocking the signal light transmission between the transmitting head and the receiving head. If the material is not loaded successfully or the position is offset, it cannot block the signal light. At this time, the receiving head can receive the signal light of the transmitting head, indicating that there is a problem with the current feeding process, and workers are required to solve and check possible hidden dangers. The technical problem that the prior art lacks detection measures for whether the feeding is successful and whether the material position is correct after completing the feeding process, resulting in inconvenience and hidden dangers in subsequent use is solved.

[0006] The technical solution adopted by the embodiment of the present application to solve the technical problem is:

[0007] A thermal protector assembly machine includes a base, on which a rotating feed table is installed, the base is provided with a loading part, a pressing part and a unloading part, a plurality of assembly carriers are provided on the rotating feed table and arranged in a circular array, and a plurality of material sensing racks are respectively arranged in the gaps between various parts of the loading part and in the gap between the loading part and the pressing part; wherein, the material sensing rack includes a mounting rod, on which a group of transmission type photoelectric sensors are installed, the transmission type photoelectric sensors include a transmitting head and a receiving head, the transmitting head is arranged above the assembly carrier, and the receiving head is arranged below the assembly carrier.

[0008] Through the above-mentioned structural form, automatic feeding is achieved by rotating the feeding table, and the loading of raw materials is completed by the loading part, the pressing part and the unloading part respectively, and the automatic closing and pressing of each component structure are completed. Finally, the unloading is completed by the unloading part. In this process, the transmitter head and the receiving head on the material sensing rack work together to detect the material. The placement of the material in the assembly carrier can be detected before proceeding to the next step. If the material is in the correct position, the signal light transmission between the transmitter head and the receiving head can be blocked. If the material is not loaded successfully or the position is offset, the signal light cannot be blocked. At this time, the receiving head can receive the signal light of the transmitter head, indicating that there is a problem with the current loading process, and workers are required to solve and check possible hidden dangers to avoid wasting energy or damaging the working head of the equipment due to air transportation.

[0009] In one possible implementation, the rotating feeding table includes a driving base, a rotating table plate is mounted on the driving base, a plurality of mounting holes distributed in a circular array are opened on the rotating table plate, and a mounting shaft is fixedly connected to the bottom of the assembly carrier, and the mounting shaft is inserted into the mounting hole.

[0011] In a possible implementation, a communicating detection through hole is formed in the middle of the assembly carrier and the installation shaft.

[0012] Through the above-mentioned structural form, the setting of the detection through hole provides a necessary path for the signal light transmission between the transmitting head and the receiving head, so that both can play a detection role, otherwise the signal light will be permanently blocked.

[0013] In a possible implementation, the signal light beam generated between the transmitting head and the receiving head during operation can pass through the middle of the detection through hole.

[0014] Through the above-mentioned structural form, it can be ensured that the signal light beam of the transmitter head has the possibility to pass through the detection through hole when working, and then be received by the receiving head. The signal light will not be permanently blocked due to obstruction by other structures, making the transmitter head and the receiving head unable to perform the detection function.

[0015] In a possible implementation, the rear ends of the transmitting head and the receiving head are both provided with vertically arranged sliding slots, and the rear ends of the transmitting head and the receiving head are threadedly connected with locking bolts.

[0016] Through the above-mentioned structural form, the transmitting head and the receiving head can slide up and down along the mounting rod, thereby adjusting the installation positions of the two to meet different needs. When the position is determined, tighten the locking bolt to fix the transmitting head and the receiving head in the current position.

[0017] In a possible implementation, a mounting foot is fixedly provided at the bottom of the mounting rod, and through strip-shaped slots are formed on both sides of the mounting foot.

[0018] Through the above-mentioned structural form, since the threaded mounting holes opened on the base are usually fixed in position, if the opening of the mounting foot is circular, its mounting position is fixed, and the strip-shaped slot hole allows the mounting foot to move slightly within a certain range, thereby facilitating the adjustment of the position of the transmitting head and the receiving head so that they are aligned with the detection through hole.

[0019] In a possible implementation, the feeding portion includes a first vibration plate feeding device, a tape feeding device, and a second vibration plate feeding device which are sequentially arranged in a counterclockwise order.

[0021] In a possible implementation, the unloading portion includes a first automatic unloading device and a second automatic unloading device, and both are equipped with a collection box.

[0022] Through the above-mentioned structural form, the finished products after assembly can be automatically unloaded and collected into a collection box, which is convenient for workers to handle them in a centralized manner on a regular basis.

[0023] In summary, the utility model includes the following beneficial technical effects:

[0024] Automatic feeding is achieved by rotating the feeding table. The loading of raw materials is completed by the feeding part, the pressing part and the unloading part respectively. Each component structure is automatically closed and pressed. Finally, the unloading is completed by the unloading part. The whole process has a high degree of automation.

[0025] During this process, the transmitter and receiver heads on the material sensing rack work together to detect the material placement in the assembly carrier before proceeding to the next step. If the material is in the correct position, it can block the signal light transmission between the transmitter and receiver heads. If the material is not loaded successfully or the position is offset, it cannot block the signal light. At this time, the receiver head can receive the signal light from the transmitter head, indicating that there is a problem with the current loading process. Workers are required to resolve and check for possible hidden dangers to avoid wasting energy by air transportation of equipment or damage to the equipment working head.

DETAILED DESCRIPTION

[0033] The technical solution in the embodiment of the present application is to solve the problems of the above-mentioned background technology, and the overall idea is as follows:

[0034] like Figure 1-3As shown, a thermal protector assembly machine provided in this embodiment includes a base 1, on which a rotating feeding table 2 is installed, and the base 1 is provided with a loading part 3, a pressing part 5 and a discharging part 6, and a plurality of assembly carriers 21 are provided on the rotating feeding table 2 and arranged in a circular array, and a plurality of material sensing racks 4 are respectively arranged in the gaps between the various parts of the loading part 3 and in the gaps between the loading part 3 and the pressing part 5. Through the above-mentioned structural form, automatic feeding is realized by the rotation of the rotating feeding table 2, and the loading of raw materials is respectively completed by the loading part 3, the pressing part 5 and the discharging part 6, and the automatic closing and pressing of each component structure are completed, and finally the discharging part 6 completes the unloading.

[0035] Among them, the material sensing frame 4 includes a mounting rod 41, on which a group of transmissive photoelectric sensors are installed. The transmissive photoelectric sensors include a transmitter head 42 and a receiver head 43. The transmitter head 42 is arranged above the assembly carrier 21, and the receiver head 43 is arranged below the assembly carrier 21. Through the above-mentioned structural form, the transmitter head 42 and the receiver head 43 on the material sensing frame 4 work together to play a material detection role, and can detect the placement of materials in the assembly carrier 21 before proceeding to the next step. If the material is in the correct position, it can block the signal light transmission between the transmitter head 42 and the receiver head 43. If the material is not loaded successfully or the position is offset, it cannot block the signal light. At this time, the receiver head 43 can receive the signal light of the transmitter head 42, indicating that there is a problem with the current loading process, and workers are required to solve and check possible hidden dangers to avoid wasting energy or damaging the equipment working head during air transportation.

[0036] like Figure 2 , 4 As shown, the rotating feeding table 2 includes a driving base 201, on which a rotating table 202 is installed. The rotating table 202 is provided with a plurality of mounting holes 203 distributed in a circular array. The bottom of the assembly carrier 21 is fixedly connected with a mounting shaft 212, and the mounting shaft 212 is inserted into the mounting hole 203. Through the above-mentioned structural form, the driving base 201 can drive the rotating table 202 to rotate, thereby driving the movement of the material in the assembly carrier 21 installed thereon, thereby completing different processes through various working mechanisms, and having the function of automatic feeding.

[0037] like Figure 2 , 4As shown, a connected detection through hole 211 is provided in the middle of the assembly carrier 21 and the installation shaft 212. Through the above-mentioned structural form, the detection through hole 211 is set to provide a necessary path for the signal light transmission between the transmitting head 42 and the receiving head 43, so that both can play a detection role, otherwise the signal light will be permanently blocked. In addition, the signal light beam generated between the transmitting head 42 and the receiving head 43 during operation can pass through the middle of the detection through hole 211. This technical solution can ensure that the signal light beam of the transmitting head 42 during operation has the possibility of passing through the detection through hole 211 and then being received by the receiving head 43. The signal light will not be permanently blocked due to the obstruction of other structures, which will make the transmitting head 42 and the receiving head 43 unable to play a detection role.

[0038] like Figure 3 As shown, the rear ends of the transmitting head 42 and the receiving head 43 are provided with vertically arranged sliding grooves 401, and the rear ends of the transmitting head 42 and the receiving head 43 are threadedly connected with locking bolts 402. Through the above-mentioned structural form, the transmitting head 42 and the receiving head 43 can slide up and down along the mounting rod 41, and then the installation positions of the two can be adjusted to meet different needs. When the position is determined, tighten the locking bolts 402 to fix the transmitting head 42 and the receiving head 43 at the current position.

[0039] In addition, a mounting foot 44 is fixedly provided at the bottom of the mounting rod 41, and through strip-shaped slots 441 are provided on both sides of the mounting foot 44. Since the threaded mounting holes provided on the pedestal 1 are usually fixed in position, if the opening of the mounting foot 44 is circular, its mounting position is fixed, and the strip-shaped slots 441 allow the mounting foot 44 to move slightly within a certain range, thereby facilitating the adjustment of the positions of the transmitting head 42 and the receiving head 43 so that they are aligned with the detection through hole 211.

[0040] like Figure 5 As shown, the loading part 3 includes a first vibration disk loading device 31, a tape loading device 32 and a second vibration disk loading device 33 which are arranged in a counterclockwise order. Through the above-mentioned structural form, the automatic loading of each component structure of the thermal protector can be completed. In addition, the unloading part 6 includes a first automatic unloading device 61 and a second automatic unloading device 62, and both of them are equipped with a collection box 601. Through the above-mentioned structural form, the finished products after assembly can be automatically unloaded and collected into the collection box 601, which is convenient for workers to handle them regularly and centrally.

[0041] The use principle and use process of this utility model:

[0042] The rotating feeding table 2 realizes automatic feeding by driving the assembly carrier 21 thereon to rotate. As the assembly carrier 21 continuously rotates, it can pass under each working mechanism, and the upper feeding part 3, the pressing part 5 and the unloading part 6 respectively complete the loading of raw materials, the automatic closing and pressing of each component structure, and the unloading of finished products. The whole process has a high degree of automation.

[0043] During this process, the transmitter head 42 and the receiving head 43 on the material sensing rack 4 work together to detect the material placement in the assembly carrier 21 before proceeding to the next step. If the material is in the correct position, it can block the signal light transmission between the transmitter head 42 and the receiving head 43. If the material is not loaded successfully or the position is offset, it cannot block the signal light. At this time, the receiving head 43 can receive the signal light from the transmitter head 42, indicating that there is a problem with the current loading process, and workers are required to solve and check possible hidden dangers to avoid wasting energy by air transportation of equipment or damage to the equipment working head.

[0044] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
