Technical Field
[0001] The utility model relates to the field of thermal protector assembly equipment, in particular to a base pushing structure of thermal protector assembly equipment. Background Art
[0002] At present, thermal protectors usually adopt bimetallic structure. There is a kind of thermal protector assembled by assembly equipment, such as Figures 8 to 10 As shown, the thermal protector includes a base assembly 99, which includes a copper base and an insulating block 991. A rivet column 993 is formed at one end of the copper base, and the other end of the copper base is buckled with the insulating block 991. A conductive block is provided in the insulating block 991, so that the conductive block is insulated from the copper base. The conductive block and the copper base are respectively connected to corresponding pins 992, as shown in FIG. Figure 10 As shown, the riveted column 993 is riveted with a copper sheet 961 and a bimetallic sheet 931. The copper sheet 961 is arranged on the upper side of the bimetallic sheet 931, and a contact is provided on the lower side of one end of the copper sheet 961 ( Figure 10 Not shown), the above-mentioned contacts are in conductive contact with the above-mentioned conductive block; during operation, when the bimetallic strip 931 is thermally deformed and lifts up the middle of the copper strip 961, the above-mentioned contacts are separated from the above-mentioned conductive block; Figure 9 As shown, an upward convex structure for supporting the shell of the thermal protector is formed on the insulating block 991 (the above-mentioned "shell" is not drawn in any of the drawings).
[0003] like Figure 7 As shown, the existing thermal protector assembly equipment is provided with a copper strip 96 unwinding wheel and a bimetallic strip unwinding wheel. The copper strip 96 has been pre-punched to form the shape of a copper sheet 961, but the rear ends of adjacent copper sheets 961 are still connected together, and the bimetallic strip is stacked on the lower side of the copper strip 96. Similarly, the bimetallic strip has been pre-punched to form the shape of a bimetallic sheet 931. The copper strip 96 and the bimetallic strip are transported to the right through the servo system, and the base assembly 99 (the above-mentioned copper seat and insulating block 991 are pre-fastened and installed together) is sorted by the vibration disk and transported to the straight vibration conveying rail 941 on the straight vibrator 94. The straight vibration conveying rail 941 transports the base assembly 99 queue to the rear end of the push block 95. At the rear side, the push block 95 moves backward and pushes the four base assemblies 99 backward onto the riveting support plate 98 at one time. The riveting support plate 98 is specifically installed on the bottom mold. The riveting die 97 moves downward, pushing the copper strip 96 and the bimetallic strip partially downward, so that the circular holes on the copper strip 96 and the bimetallic strip are sleeved on the corresponding riveting columns 993. As the riveting die 97 moves downward, the riveting die 97 flattens the riveting columns 993, so that the copper sheet 961 and the bimetallic sheet 931 are firmly riveted to the above-mentioned copper seat. The riveting die 97 rises, and the copper strip 96 and the bimetallic strip elastically recover and lift the base assembly 99. In the subsequent process, the copper strip 96 and the bimetallic strip are cut, so that Figure 8 Thermal protector shown (semi-finished product).
[0004] In actual application, the base assembly 99 at the front of the queue is pushed to the rear side of the rear end of the push block 95 by the base assembly 99 queue, but since the base assembly 99 loses the guided effect after leaving the straight vibration conveyor rail 941, the base assembly 99 may be horizontally tilted at the rear side of the push block 95, making it impossible for the designed number (for example, four) of base assemblies 99 to dock at the corresponding rear side of the push block 95. Moreover, when the push block 95 moves backward, the base assembly 99 is stuck in the feeding channel, requiring shutdown processing, affecting production efficiency, so it is necessary to improve the pushing structure for the base assembly 99 in the prior art.

DETAILED DESCRIPTION
[0025] The present invention will be further described below in conjunction with the accompanying drawings.
[0026] The base pushing structure of the thermal protector assembly equipment of the utility model is as follows Figure 1 and Figure 2 As shown, it includes a support 1, such as Figure 2 and Figure 6 As shown, the support 1 is provided with a material distribution position 111 for temporarily storing the base assembly 99. For example, the material distribution position 111 can temporarily store four base assemblies 99. Specifically, the left side of the support 1 is formed with a material inlet 101, as shown in FIG. Figure 7 As shown, the end of the straight vibration conveyor rail 941 is connected to the feed inlet 101, wherein the material distribution position 111 is flush with the feed inlet 101 in the vertical direction, and the feed inlet 101 is connected to the material distribution position 111. Figure 1 As shown, a push plate 2 is slidably provided on the support 1, and a push cylinder 3 is provided on the support 1. The push cylinder 3 drives the front end of the push plate 2. Specifically, the push cylinder 3 includes a push cylinder body 31 and a push piston rod 32. The push cylinder body 31 is fixed to the front end of the support 1 by corresponding screws. The push piston rod 32 is screwed with a T-block. The T-block is inserted into the T-slot at the front end of the push plate 2 in the vertical direction, so that the push piston rod 32 can drive the push plate 2 to move forward and backward. Figure 2 and Figure 3 As shown, the rear end of the push plate 2 is provided with a pushing end 201 for pushing the base assembly 99 backward from the material distribution position 111 to the riveting support plate 98. In other words, the material distribution position 111 and the riveting support plate 98 are set at the same height, so that the base assembly 99 can be translated to the riveting support plate 98. Figure 2 and Figure 3As shown, the support 1 is hinged with a swing arm 4, and a guide plate 401 is formed at the lower end of the swing arm 4. The support 1 is provided with a swing arm cylinder 5, which drives the swing arm 4 to swing. The swing axis of the swing arm 4 extends in the left and right directions. The guide plate 401 has a first position and a second position relative to the pusher end 201; Figure 3 and Figure 4 As shown, in the first position, the guide plate 401 is located at the rear side of the pushing end 201, and a groove 200 is formed between the guide plate 401 and the pushing end 201 for the insulating block 991 of the base assembly 99 to slide horizontally (i.e., in the left and right directions). Specifically, the upper convex structure of the insulating block 991 can slide in the groove 200; in the second position, the guide plate 401 is located higher than the push plate 2, that is, the swing arm cylinder 5 drives the swing arm 4 to swing clockwise (in the left and right directions). Figure 3 In the visual direction), the guide plate 401 can be swung backward and upward to separate from the push plate 2. Then, when the push cylinder 3 drives the push plate 2 to move backward, the push plate 2 will not hit the swing arm 4.
[0027] The following briefly describes the working principle of the present invention: the straight vibration conveyor rail 941 conveys the base assembly 99 queue (from left to right) to the feed port 101, and then the base assembly 99 enters the dispensing position 111. During this period, the upper convex structure of the insulating block 991 of the first base assembly 99 in the base assembly 99 queue slides into the groove 200. Through the guiding effect of the groove 200, the base assembly 99 that has left the straight vibration conveyor rail 941 can still maintain a straight line movement to the right and avoid skewing. That is to say, in the process of the base assembly 99 transitioning from the feed port 101 to the dispensing position 111, the groove 200 has already played a guiding role for the base assembly 99. Afterwards, the base assembly 99 completely slides into the dispensing position 111. The base assembly 99 moves in a straight line to the right along the groove 200, and then the first four base assemblies 99 in the queue enter the material distribution position 111, and then the swing arm piston rod 52 of the swing arm cylinder 5 contracts and moves, driving the swing arm 4 to swing clockwise, so that the guide plate 401 reaches the above-mentioned second position, and the pushing cylinder 3 pushes the push plate 2 backward, and the push plate 2 closes the feed port 101, and the pushing end 201 pushes the above-mentioned four base assemblies 99 backward to the riveting support plate 98. During this period, since the four base assemblies 99 can be neatly arranged at the material distribution position 111 under the guiding action of the groove 200, the pushing end 201 pushes the above-mentioned four base assemblies 99 without getting stuck, which is beneficial to the stable operation of the thermal protector assembly equipment and the improvement of production efficiency. After the pusher end 201 pushes the base assembly 99 onto the riveting support plate 98, the pusher cylinder 3 pulls the push plate 2 forward to reset it, allowing the feed port 101 to resume communication with the dispensing position 111. The swing arm cylinder 5 then drives the swing arm 4 to swing counterclockwise to reset it to the first position described above. As can be seen from the above, by configuring the swing arm cylinder 5 in conjunction with the swing arm 4, the channel 200 structure can be disassembled after several (for example, four) base assemblies 99 are neatly aligned and abutted against each other at the dispensing position 111, thereby avoiding obstruction to the backward movement of the base assembly 99.
[0028] Furthermore, if Figure 6 As shown, the support 1 is provided with a guide side plate 12, as shown in FIG. Figure 1 As shown, the push plate 2 is adapted to be disposed between the left and right guide side plates 12. Specifically, as shown in FIG. Figure 6 As shown, the support 1 is further provided with a sliding support platform 11, and a material distribution position 111 is formed on the sliding support platform 11. The material distribution position 111 is located between the left and right guide side plates 12, as shown in FIG. Figure 2 and Figure 3 As shown, the push plate 2 is abutted against the upper side of the sliding support platform 11, and the guide side plate 12 prevents the push plate 2 from swinging left and right, which is conducive to accurately pushing the base assembly 99 to the riveting support plate 98. Figure 6 As shown, the feed port 101 can be formed on the corresponding guide side plate 12. Figure 1 and Figure 6 As shown, the front portion of the aforementioned feeding channel is located between the left and right guide side plates 12 .
[0029] Furthermore, if Figure 1 As shown, the swing arm 4 is adapted to be arranged between the left and right guide side plates 12 to prevent the swing arm 4 from loosening left and right. The swing arm 4 is connected to the guide side plates 12 through a hinge shaft 41. The above arrangement utilizes the structural support of the guide side plates 12 to connect the swing arm 4, which is conducive to simplifying the base pushing structure of the utility model.
[0030] Furthermore, if Figures 1 to 3 As shown, the upper end of the swing arm 4 is formed with a fork 402, and the swing arm cylinder 5 is provided with a swing arm piston rod 52. The swing arm piston rod 52 is screwed with a hinge 521. The hinge 521 (in the left-right direction) is adapted to be arranged in the fork 402. The rear end of the hinge 521 is hinged to the upper end of the swing arm 4. The hinge shaft 41 is provided between the guide plate 401 and the fork 402. The above arrangement facilitates the arrangement of the hinge 521 in the center relative to the swing arm 4 in the left-right direction, which helps to balance the force on the swing arm 4. Figure 1 As shown, the swing arm cylinder 5 is provided with a swing arm cylinder body 51 , and the front end of the swing arm cylinder body 51 is hinged to the support 1 .
[0031] Furthermore, if Figure 3 、 Figure 4 and Figure 6 As shown, a groove 1101 extending in the left-right direction is formed on the material distribution position 111, and the groove 1101 can be a V-shaped groove, such as Figure 6 As shown, the grooves 1101 can be arranged at intervals in the front-to-back direction. The bottom of the base assembly 99 inevitably has burrs. By providing the grooves 1101 structure, when the base assembly 99 is transported to the dispensing position 111 by the straight vibrator 94, the grooves 1101 can avoid some of the above-mentioned burrs. In other words, some of the burrs on the bottom of the base assembly 99 can avoid scratching the top of the dispensing position 111, thereby reducing the resistance encountered by the base assembly 99 when it slides horizontally on the dispensing position 111.
[0032] Furthermore, if Figure 5 As shown, the pushing end 201 is formed with an inverted step 2011 (in other words, the inverted step 2011 is an inverted step structure), as shown in FIG. Figure 3 and Figure 4As shown, in the first position, the guide plate 401 is in contact with the pusher end 201, and the channel 200 is formed in the upper inverted step 2011. Thus, the rear end face of the pusher end 201 blocks the positioning guide plate 401, so that the front face of the guide plate 401 and the wall of the upper inverted step 2011 can form a channel 200 with a stable shape. In addition, the upper inverted step 2011 can guide the lateral sliding of the base assembly 99 on the upper side of the insulating block 991 of the base assembly 99, thereby preventing the base assembly 99 from arching over the material distribution position 111. Figure 3 and Figure 5 As shown, the pushing end 201 is formed with a lower step 2012 for avoiding the pin 992 of the base assembly 99, that is, the lower step 2012 is located on the lower side of the upper step 2011, so that when the push plate 2 moves backward, it is actually the upper step 2011 that contacts and pushes the insulating block 991 to move backward, thereby avoiding damage to the pin 992.
