Based on the embodiments provided in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0043] In the present application, referring to "embodiment" means that the specific features, structures or characteristics described in conjunction with the embodiment may be included in at least one embodiment of the present application. The phrase appears at various positions in the specification does not necessarily refer to the same embodiment, nor is it an exclusive, independent or alternative embodiment that is mutually exclusive with other embodiments. Those skilled in the art can explicitly and implicitly understand that the embodiments described in the present application can be combined with other embodiments.

[0044] The terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish different objects, rather than to describe a specific order. In addition, the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion. For example: a component or device including one or more components is not limited to the one or more components listed, but optionally further includes one or more components not listed but inherent in the product shown, or one or more components that should be had based on the described function.

[0045] Please refer to Figure 1 and Figure 2The present application provides a conveyor belt fixture that is compatible with open-loop and closed-loop conveyor belts, namely, a conveyor belt fixture 100. The conveyor belt fixture 100 is fixed on the conveyor belt, and a processing head can be fixed on the conveyor belt fixture 100, which can drive the processing head to move when the conveyor belt moves, so as to achieve processing along a preset motion trajectory.

[0046] The conveyor belt fixing member 100 is roughly block-shaped. The conveyor belt can be a belt, a steel wire rope, etc.

[0047] See also Figure 1 and Figure 2 The conveyor belt fixing element 100 includes a first surface 101 and a second surface 102 that are disposed opposite to each other, and a peripheral side surface 103 connected between the first surface 101 and the second surface 102 .

[0048] The first surface 101 may be the front side of the conveyor belt fixing element 100 , and the second surface 102 may be the back side of the conveyor belt fixing element 100 .

[0049] See also Figure 1 and Figure 2 The peripheral side surface 103 may be a surface between the first surface 101 and the second surface 102 and disposed around the conveyor belt fixing member 100 (e.g., left, right, top, and bottom sides). For ease of description, the direction in which the first surface 101 and the second surface 102 are opposite to each other is defined as the X direction, the direction in which the left side surface and the right side surface are opposite to each other is defined as the Y direction, and the direction in which the top surface and the bottom surface are opposite to each other is defined as the Z direction.

[0050] See also Figure 1 and Figure 2 The conveyor belt fixing member 100 has a receiving passage 110 therein. The receiving passage 110 is used to receive the conveyor belt 200 .

[0051] The receiving channel 110 passes through the first surface 101, and the receiving channel 110 can be regarded as a receiving groove opened from the first surface 101 to the second surface 102. The opening of the receiving channel 110 is set on the first surface 101, and the receiving channel 110 does not pass through the second surface 102, so that the conveyor belt fixing member 100 has a certain structural strength. By setting the receiving channel 110 to pass through the first surface 101, it is convenient to insert the conveyor belt 200 into the receiving channel 110 from the first surface 101. At this time, the depth (dimension along the X direction) of the receiving channel 110 can be greater than or equal to the width (dimension along the X direction) of the conveyor belt 200, so that the conveyor belt 200 can be completely accommodated in the receiving channel 110.

[0052] See also Figures 1 to 3 At least one side wall of the receiving channel 110 is provided with a first tooth pattern 120. The first tooth pattern 120 is used to mesh with the tooth pattern on the conveyor belt 200.

[0053] Optional, seeFigure 4 , the receiving channel 110 includes a bottom wall 111 and opposite first and second side walls 112 and 113. The bottom wall 111 faces the opening of the receiving channel 110.

[0054] In the first alternative embodiment, refer to Figure 5 and Figure 6 , a first tooth pattern 120 is provided on the first side wall 112. The first side wall 112 is the upper side wall, and the conveyor belt fixing member 100 can be fixed to the lower conveyor belt 200 of the conveyor belt 200. Correspondingly, a second tooth pattern 130 is provided on the side of the conveyor belt 200 facing the upper side wall, and the second tooth pattern 130 meshes with the first tooth pattern 120. At the same time, the second side wall 113 is a plane, and the surface of the conveyor belt 200 facing the second side wall 113 is also a plane. The second side wall 113 fits against the surface of the conveyor belt 200 facing the second side wall 113 to achieve the engagement between the conveyor belt 200 and the conveyor belt fixing member 100.

[0055] In the second alternative embodiment, a first tooth pattern 120 is provided on the second side wall 113. The second side wall 113 is the lower side wall, and the conveyor belt fixing member 100 can be fixed to the upper conveyor belt 200 of the conveyor belt 200. Correspondingly, a second tooth pattern 130 is provided on the side of the conveyor belt 200 facing the lower side wall, and the second tooth pattern 130 meshes with the first tooth pattern 120. At the same time, the second side wall 113 is a plane, and the surface of the conveyor belt 200 facing the second side wall 113 is also a plane. The second side wall 113 fits against the surface of the conveyor belt 200 facing the second side wall 113 to achieve the engagement between the conveyor belt 200 and the conveyor belt fixing member 100.

[0056] In the third alternative embodiment, first tooth patterns 120 are provided on both the first side wall 112 and the second side wall 113. The first side wall 112 is the upper side wall, and the second side wall 113 is the lower side wall. The conveyor belt fixing member 100 can be fixed to the upper conveyor belt 200 or the lower conveyor belt 200 of the conveyor belt 200. Correspondingly, second tooth patterns 130 are provided on both the upper and lower sides of the conveyor belt 200, and the second tooth patterns 130 mesh with the first tooth patterns 120. The upper and lower sides of the conveyor belt 200 are respectively engaged with the first side wall 112 and the second side wall 113 to achieve the fixation between the conveyor belt 200 and the conveyor belt fixing member 100.

[0057] In this embodiment, the conveyor belt 200 uses the mutual engagement between the toothed belt material and the pulley to keep the rotational speeds of the two synchronized. The tooth pattern of the conveyor belt 200 and the groove on the conveyor belt fixing member 100 are engaged with each other to prevent the conveyor belt 200 from sliding, thereby ensuring the transmission efficiency and accuracy.

[0058] Please refer to Figures 1 to 6, the receiving channel 110 forms at least three channel openings 140 on the circumferential side surface 103. The channel openings 140 are used to guide the conveyor belt 200 into or out of the receiving channel 110. Optionally, the receiving channel 110 extends in different directions within the conveyor belt fixing member 100.

[0059] This application does not specifically limit the number of channel openings 140 formed by the receiving channel 110 on the circumferential side surface 103. Optionally, the number of channel openings 140 formed by the receiving channel 110 on the circumferential side surface 103 includes, but is not limited to, three, four, five, six, etc. This embodiment does not specifically limit the specific side surface of the channel opening 140.

[0060] Currently, the commonly used conveyor belt fixing members include two forms: open-loop and closed-loop. The fixing members between these two forms of conveyor belts are not compatible. The size selectivity of the closed-loop conveyor belt is relatively small, and there are also differences in materials and performance, resulting in the conveyor belt on some equipment not being replaced in time after being damaged, which affects the processing efficiency.

[0061] Generally, the closed-loop conveyor belt enters and exits through two channel openings respectively.

[0062] Please refer to Figure 5 , for the closed-loop conveyor belt 200, since the closed-loop conveyor belt 200 has no free end, the closed-loop conveyor belt 200 can enter the receiving channel 110 through one channel opening 140 and exit the receiving channel 110 through another channel opening 140. Please refer to Figure 6 , for the open-loop conveyor belt 200, the open-loop conveyor belt 200 includes two free ends. The two free ends of the open-loop conveyor belt 200 penetrate into the receiving channel 110 through two different channel openings 140 respectively, and exit the receiving channel 110 through one or two channel openings 140, so as to enable the conveyor belt fixing member 100 to be compatible with both open-loop and closed-loop conveyor belts 200.

[0063] The conveyor belt fixing member 100 provided by the present application is designed such that the conveyor belt fixing member 100 includes a first surface 101 and a second surface 102 disposed opposite to each other, and a circumferential side surface 103 connected between the first surface 101 and the second surface 102. The conveyor belt fixing member 100 has a receiving channel 110 for receiving the conveyor belt 200. The receiving channel 110 penetrates the first surface 101 so that the conveyor belt 200 can be inserted into the receiving channel 110 through the opening on the first surface 101. At least one side wall of the receiving channel 110 is provided with a first tooth pattern 120 for meshing with the tooth pattern on the conveyor belt 200, so that the conveyor belt engages with the conveyor belt fixing member 100 to improve the transmission efficiency between the conveyor belt 200 and the conveyor belt fixing member 100. The receiving channel 110 forms at least three channel openings 140 on the circumferential side surface 103. The channel openings 140 are used to guide the conveyor belt 200 to enter or exit. There are at least three channel openings 140 on the fixing member, so that the closed-loop conveyor belt 200 can enter the receiving channel 110 through one channel opening 140 and exit the receiving channel 110 through another channel opening 140, and the two free ends of the open-loop conveyor belt 200 can respectively penetrate into the receiving channel 110 through two different channel openings 140 and exit the receiving channel 110 through one or two channel openings 140, so as to be compatible with both open-loop and closed-loop conveyor belts 200.

[0064] In the case where even the closed-loop conveyor belt 200 is damaged, it can be replaced with an open-loop conveyor belt 200 without replacing the conveyor belt fixing member 100. In addition, the conveyor belt fixing member 100 provided in this embodiment can not only be used for the compatibility of open-loop conveyor belts 200 and closed-loop conveyor belt fixing members 100, but also be applicable to the scenario of non-closed-loop rotary motion.

[0065] In an alternative embodiment, please refer to Figure 5 and Figure 6 , the circumferential side surface 103 includes a first side surface 1031 and a second side surface 1032 disposed opposite to each other. The first side surface 1031 and the second side surface 1032 are surfaces disposed opposite to each other along the Y direction. Further, when the conveyor belt fixing member 100 is disposed on the conveyor belt 200, the conveyor belt 200 extends along the Y direction.

[0066] Please refer to Figure 5 and Figure 6 , at least three channel openings 140 include a first channel opening 141 and a second channel opening 142.

[0067] The first channel opening 141 is disposed on the first side surface 1031. The second channel opening 142 is disposed on the second side surface 1032. The first channel opening 141 and the second channel opening 142 are opposite to each other.

[0068] Please refer to Figure 5For the closed-loop conveyor belt 200, the closed-loop conveyor belt 200 can enter the receiving channel 110 from the first channel opening 141 and exit the receiving channel 110 through the second channel opening 142.

[0069] Since the first channel opening 141 is provided on the first side surface 1031 and the second channel opening 142 is provided on the second side surface 1032, the first channel opening 141 and the second channel opening 142 are directly opposite to each other. After the conveyor belt 200 enters the first channel opening 141 along the Y direction, it still extends along the Y direction after passing through the first channel opening 141. In other words, the arrangement of the first channel opening 141 and the second channel opening 142 in this embodiment is adapted to the extending direction of the conveyor belt 200, so that the conveyor belt 200 entering from the first channel opening 141 and exiting from the second channel opening 142 remains horizontal.

[0070] This embodiment does not specifically limit the extending direction of the path of the receiving channel 110 between the first channel opening 141 and the second channel opening 142. Optionally, the receiving channel 110 between the first channel opening 141 and the second channel opening 142 extends in a straight line, or a bent line, or a curved line.

[0071] Optionally, please refer to Figure 5 , the circumferential side surface 103 further includes a third side surface 1033 connected between the first side surface 1031 and the second side surface 1032. The third side surface 1033 can be the aforementioned bottom surface or top surface. Taking the bottom surface as an example.

[0072] Please refer to Figure 5 , at least three channel openings 140 further include a third channel opening 143. The third channel opening 143 is provided on the third side surface 1033. For the open-loop conveyor belt 200, the two free ends of the open-loop conveyor belt 200 respectively enter the receiving channel 110 from the first channel opening 141 and the second channel opening 142, and exit the receiving channel 110 through the third channel opening 143.

[0073] Please refer to Figure 7 , the receiving channel 110 includes a first sub-channel 1101 and a second sub-channel 1102 that are connected.

[0074] Please refer to Figure 7 , the two channel openings 140 at both ends of the first sub-channel 1101 are respectively the first channel opening 141 and the second channel opening 142. In other words, the channel between the first channel opening 141 and the second channel opening 142 is the first sub-channel 1101. The first sub-channel 1101 further includes a first internal channel opening 145 located between the first channel opening 141 and the second channel opening 142.

[0075] One end of the second sub-channel 1102 is connected to the portion between the two end channel openings 140 of the first sub-channel 1101, that is, the aforementioned first internal channel opening 145. The other end channel opening 140 of the second sub-channel 1102 is the third channel opening 143.

[0076] Please refer to Figure 1 and Figure 5 , thus, for the closed-loop conveyor belt 200, a part of the conveyor belt 200 can be disposed within the first sub-channel 1101, and the second tooth patterns 130 on the conveyor belt 200 engage with the first tooth patterns 120 on the two side walls of the first sub-channel 1101, realizing a firm connection between the conveyor belt 200 and the conveyor belt fixing member 100.

[0077] Please refer to Figure 3 and Figure 6 , for the open-loop conveyor belt 200, the first free end 210 of the conveyor belt 200 enters a part of the first sub-channel 1101 through the first channel opening 141, enters the second sub-channel 1102 through the first internal channel opening 145, and then exits through the third channel opening 143. The second free end 220 of the conveyor belt 200 enters another part of the first sub-channel 1101 through the second channel opening 142, enters the second sub-channel 1102 through the first internal channel opening 145, and then exits through the third channel opening 143. At the same time, the first tooth patterns 120 on the upper side wall of the first sub-channel 1101 engage with the second tooth patterns 130 on the conveyor belt 200, and the first free end 210 of the conveyor belt 200 engages with the second free end 220. Further, the first tooth patterns 120 on the lower side wall of the first sub-channel 1101 can engage with the second tooth patterns 130 on the lower surface of the conveyor belt 200, and the first free end 210 of the conveyor belt 200 can also engage with the first tooth patterns 120 on one side of the second sub-channel 1102, and the second free end 220 of the conveyor belt 200 can also engage with the first tooth patterns 120 on the other side of the second sub-channel 1102 to further increase the firmness of the connection between the conveyor belt 200 and the conveyor belt fixing member 100.

[0078] Optionally, the first sub-channel 1101 is linear, and the first internal channel opening 145 is located near the middle position of the first sub-channel 1101. Thus, the receiving channel 110 is generally in a T shape.

[0079] In another alternative embodiment, please refer to Figure 8 , the first sub-channel 1101 is generally in a V shape, and the receiving channel 110 is generally in a Y shape.

[0080] By setting the first sub-channel 1101 to be V-shaped, the bending degree of the path of the conveyor belt 200 is increased to further increase the firmness of the connection between the conveyor belt 200 and the conveyor belt fixing member 100.

[0081] Optionally, refer to Figure 7 , the channel spacing of the second sub-channel 1102 is greater than that of the first sub-channel 1101 to facilitate accommodating the double-layer conveyor belt 200 in the second sub-channel 1102.
